How to prevent deformation of silicone sealing rings? Silicone sealing rings are widely used in food, medical, industrial equipment and other fields due to their excellent high and low temperature resistance, aging resistance and environmental protection characteristics. However, during use, the sealing ring often experiences deformation problems such as twisting and crushing due to material defects, unreasonable design, or improper operation, leading to sealing failure, equipment leakage, and even shutdown risks. According to statistics, about 60% of early failures of silicone seals are caused by deformation damage. Deformation not only shortens product lifespan, but may also pose safety hazards.   Optimize product structure design Reasonably design the cross-sectional shape of the sealing ring, for example, for some high-pressure environments, a combination sealing structure can be used, combining the silicone rubber sealing ring with other sealing components to disperse pressure and reduce the deformation of the sealing ring. In hydraulic systems, a combination of O-ring and retaining ring can be used. The retaining ring can provide support for the O-ring and prevent it from being squeezed into the gap and deformed under high pressure.   Determine the appropriate sealing ring size based on different working conditions and sealing requirements. For example, for motion seals, it is necessary to ensure that the sealing ring has sufficient elasticity to compensate for the gap changes between moving parts, while also avoiding excessive compression deformation caused by oversized dimensions.   Increase product strength design By adding an appropriate amount of reinforcing agent to silicone rubber, the strength and rigidity of the sealing ring can be improved. Common reinforcing agents include white carbon black, calcium carbonate, etc. White carbon black is a commonly used reinforcing agent for silicone rubber, which can form a good bond with silicone rubber molecules and improve the mechanical properties such as tensile strength and tear strength of silicone rubber. Generally, during the mixing process of silicone rubber, white carbon black is added in a certain proportion (such as 10-30 parts white carbon black/100 parts silicone rubber), and after thorough mixing, the reinforcing agent is uniformly dispersed in the silicone rubber matrix.   In terms of production and manufacturing Optimize processing technology Strictly control the vulcanization process parameters, including vulcanization temperature, time, pressure, etc. The vulcanization process is a key step in the formation of silicone rubber seals, and appropriate vulcanization conditions can form stable cross-linked structures between the molecular chains of silicone rubber, thereby improving the performance of the seals. For example, for general silicone rubber materials, the vulcanization temperature is usually between 150-200 ℃, the vulcanization time depends on factors such as product thickness, and is generally between 5-20 minutes. The vulcanization pressure is generally between 5-15MPa. If the vulcanization is insufficient, the strength and elasticity of the sealing ring will be insufficient, and it is easy to deform; Excessive vulcanization can cause the sealing ring to become hard and brittle, and also reduce its service life. To ensure the accuracy and quality of the mold, it is necessary to ensure that the dimensional accuracy and surface roughness of the mold cavity meet the requirements during the mold design and manufacturing process. High precision molds can ensure that the silicone rubber sealing ring can accurately fill the cavity during the molding process, reducing the size deviation and internal stress concentration of the sealing ring caused by mold problems, thereby reducing the possibility of deformation.   In terms of usage and maintenance Proper use and installation When installing the sealing ring, ensure that it is correctly installed in the predetermined position to avoid twisting, excessive stretching, and other situations. For example, when installing an O-ring, specialized installation tools such as mounting rods or rings should be used to evenly push the O-ring into the sealing groove. Excessive force or sharp tools should not be used to directly insert it to avoid damaging the sealing ring. Reasonably select the working pressure and temperature range of the sealing ring to operate within the allowable range of the design. If the work pressure or temperature exceeds the bearing range of the sealing ring, the sealing ring is prone to deformation, aging and other problems. If working in a high-temperature environment, silicone rubber materials with better high-temperature resistance should be selected, and the cross-sectional area of the sealing ring should be appropriately increased to improve its pressure resistance.   Regular maintenance and inspection Regularly inspect the sealing ring to see if there is any deformation, wear, aging, or other phenomena. For some long-term equipment, a regular maintenance plan can be developed, such as checking the condition of the sealing ring once a month or every quarter. If slight deformation is found in the sealing ring, the development of deformation can be slowed down by adjusting the working parameters of the equipment (such as reducing pressure, temperature, etc.), while closely observing the changes in the sealing ring. Timely clean the impurities and oil stains on the surface of the sealing ring. Impurities may cause scratches or increase the friction between the sealing ring and the sealing surface, leading to deformation of the sealing ring. Use appropriate cleaning agents (such as alcohol) and cleaning tools (such as a soft bristled brush) to clean the sealing ring, but be careful to avoid corrosion of the sealing ring material by the cleaning agent.   In terms of environmental control temperature control Try to avoid exposing equipment and sealing rings to extreme temperature environments. If the equipment needs to work in a high-temperature environment, insulation measures can be considered, such as adding a heat shield outside the equipment to reduce heat transfer to the sealing ring. For low-temperature environments, appropriate insulation measures can be taken, such as using heating belts to insulate the sealing ring during equipment shutdown, to prevent the sealing ring from becoming brittle or deformed due to low temperature. Humidity control High humidity environments may cause silicone rubber seals to absorb water and expand, especially in situations where sealing requirements are high. The sealing ring after absorbing water and expanding may cause sealing failure. Dehumidification equipment can be used to reduce environmental humidity, or desiccants can be installed inside the equipment to absorb moisture and keep the environment around the sealing ring dry. Avoid chemical corrosion environment Understand the chemical properties of the medium that silicone rubber seals come into contact with, and avoid long-term contact between the seals and highly corrosive chemicals. If it must be used in an environment with corrosive media, silicone rubber materials with corresponding chemical corrosion resistance should be selected. For example, for some acidic or alkaline media, acid alkali resistant silicone rubber seals designed with special formulas can be used. At the same time, it is necessary to regularly check the corrosion of the sealing ring and the contact area with the medium, and replace damaged sealing rings in a timely manner.

In order to improve the cold resistance of rubber materials, researchers have adopted various methods. These methods mainly include rubber copolymerization and chemical modification, rubber blending, addition of plasticizers, rational selection of vulcanization and filling systems, etc.   1. Rubber copolymerization and chemical modification Rubber copolymerization and chemical modification are effective methods to improve the cold resistance of rubber materials. By introducing monomers with large side groups for copolymerization, the regularity of rubber molecular chains can be disrupted, and their Tg and Tb can be reduced. For example, introducing monomers with flexible structures into fluororubber molecules can increase the flexibility of the molecular chain, reduce intermolecular forces, and thus improve the cold resistance of fluororubber. In addition, chemical modification methods such as epoxidation and isomerization can be used to alter the structure of rubber molecular chains and improve their cold resistance.   2.Rubber blending is a common method to adjust cold resistance in rubber formula design. By combining different types of rubber, their respective advantages can be comprehensively utilized to improve the cold resistance of rubber materials. For example, combining styrene butadiene rubber (SBR) with butadiene rubber (BR) can improve the cold resistance of the rubber. This is because SBR and BR have lower Tg and good molecular chain flexibility, and can still maintain a certain degree of elasticity at low temperatures.   3.Adding plasticizers is one of the effective measures to improve the cold resistance of rubber materials. Plasticizers can increase the flexibility of rubber molecular chains, reduce intermolecular forces, and make molecular segments easier to move. At low temperatures, plasticizers can act as lubricants, reducing friction and resistance between rubber molecular chains, thereby improving the cold resistance of rubber. Common plasticizers include petroleum based hydrocarbon solvent plasticizers and non solvent plasticizers.

Rebound rate, also known as rebound elasticity or impact elasticity, is an important performance indicator for measuring rubber elasticity. The ratio of the height of the rebound to the original height when using a pendulum to impact rubber at a certain height is called the rebound rate, expressed as a percentage (%). The larger the value, the higher the elasticity of the rubber.   Tear off permanent deformation, also known as permanent deformation, is an important indicator for measuring the elasticity of rubber. It is the ratio of the length increased by the deformed part of the rubber after it is stretched and pulled apart and parked for a certain period of time (usually 3 minutes) to the original length, expressed as a percentage (%). The smaller its diameter, the better the elasticity of the rubber. In addition, the elasticity of rubber can also be measured by compressive permanent deformation.   Tensile strength: also known as tensile strength. It refers to the force required per unit area for rubber to elongate to a certain length, that is, to elongate to 100%, 200%, 300%, 500%. Expressed in N/cm2. This is an important mechanical indicator for measuring the strength and toughness of rubber. The larger its value, the better the rubber's resilience, indicating that this type of rubber is less prone to elastic deformation.

How to control the hardness of silicone products? In the production process of silicone products, hardness control is a crucial link, which directly affects the performance and user experience of the product.   1. Hardness control method for silicone products Choose appropriate raw materials The different hardness of silicone raw materials directly affects the hardness of the final product. Normally, suppliers will provide silicone raw materials with different hardness, such as 30 degrees, 50 degrees, 70 degrees, etc. Producers can choose suitable hardness raw materials according to product requirements. Mixing silicone rubber material In actual production, it is often necessary to achieve the desired hardness value by blending different hardness rubber materials. By mixing high hardness and low hardness rubber materials, any hardness between the two can be formulated. Adjust hardness with silicone oil Silicone oil can be used to reduce the hardness of silicone gel. Adding an appropriate amount of silicone oil to silicone can effectively adjust the hardness of silicone products. However, it should be noted that excessive silicone oil may affect the physical properties and service life of silicone.   2. Adjustment formula for hardness of silicone products In practical operation, in order to accurately adjust the hardness of silicone products, the following two formulas can be used for calculation: Adjustment formula for high hardness of silicone rubber material If the measured hardness value is higher than the required hardness value, the weight of low hardness rubber material to be added can be calculated according to the following formula: [Weight of low hardness rubber material to be added in ext}=rac {(measured hardness value) - ext {required hardness value})} {(ext {required hardness value} - ext {low hardness value})} times the weight of ext {rubber material}] Adjustment formula for low hardness of silicone rubber material If the measured hardness value is lower than the required hardness value, the weight of the required high hardness rubber material can be calculated according to the following formula: [Weight of required high hardness adhesive for ext=rac {(ext {required hardness value} - ext {measured hardness value})} {ext {high hardness value} - ext {measured hardness value})} times the weight of ext {adhesive}] Through these two formulas, producers can adjust the hardness of silicone products according to actual needs to ensure that the products meet specific performance requirements.   The hardness control of silicone products is a precise technical process, through the reasonable selection of raw materials, the allocation of rubber materials and the use of adjustment formulas, can effectively control the hardness of silicone products to meet the needs of different application scenarios. Mastering these technologies is of great significance for improving product quality and production efficiency.

Do silicone parts have any requirements for raw materials? In modern industrial manufacturing, silicone parts are widely used in various fields due to their unique physical and chemical properties. However, the performance and quality of silicone parts largely depend on the selection of their raw materials. So, do silicone parts have any requirements for raw materials?   The primary requirement for raw materials in silicone parts is material purity. High purity silicone raw materials can ensure stable chemical properties of parts during the manufacturing process, reducing the impact of impurities on part performance. For example, in the medical field, silicone parts need to have high biocompatibility and chemical stability, which requires that the raw materials must not contain impurities that are harmful to the human body. Therefore, when selecting silicone raw materials, it is necessary to ensure that their purity meets relevant standards to meet the specific application requirements.   In addition to purity requirements, the hardness of silicone parts is also a key factor in the selection of raw materials. The hardness of silicone directly affects the support and flexibility of the parts. If the hardness is too high, the parts may be too rigid to adapt to complex shapes and stress changes; If the hardness is too low, the parts may be too soft and prone to deformation or damage. Therefore, when selecting silicone raw materials, it is necessary to choose silicone materials with appropriate hardness according to the specific purpose and working environment of the parts.   Temperature resistance is another important requirement of silicone parts for raw materials. Silicone parts need to maintain stable performance in different temperature environments, including resistance to brittleness at low temperatures and heat resistance at high temperatures. This requires raw materials to have excellent temperature resistance and be able to maintain stable chemical and physical properties under extreme temperature conditions. For example, in the automotive industry, silicone parts need to be able to withstand the high temperature environment inside the engine compartment, which requires raw materials to have excellent heat resistance.   Dimensional accuracy and shape integrity are also important requirements for silicone parts in terms of raw materials. Silicone parts usually need to be customized according to specific sizes and shapes, which requires raw materials to have high plasticity and processing performance. During the manufacturing process, raw materials need to undergo precise mold forming and processing to ensure the dimensional accuracy and shape integrity of the parts. If the plasticity and processing performance of raw materials are poor, it may lead to inaccurate dimensions or incomplete shapes of parts, thereby affecting their usability.   In addition, silicone parts also have certain requirements for the physical properties of raw materials. For example, elastic recovery ability and wear resistance are important properties that silicone parts need to possess during use. Silicone parts with strong elastic recovery ability can quickly recover to their original state after being subjected to external forces, maintaining stable shape and performance. Silicone parts with good wear resistance can reduce wear and damage during long-term use, extending their service life. These performance requirements need to be considered when selecting raw materials.   Chemical properties are another key requirement for raw materials in silicone parts. Silicone parts need to be able to maintain stable performance in the face of various chemical substances, including corrosive substances such as acids, alkalis, and salts. This requires raw materials to have excellent chemical corrosion resistance and maintain stable chemical properties when in contact with these chemicals. At the same time, raw materials also need to have good chemical stability to avoid performance degradation caused by chemical reactions during use.   Silicone parts have strict requirements for raw materials. These requirements cover multiple aspects such as purity, hardness, temperature resistance, dimensional accuracy, shape integrity, physical properties, and chemical properties.

The hot pressing process of silicone products has become an indispensable material in many fields in modern industrial production due to its excellent temperature resistance, corrosion resistance, and good physical properties. As a key technology in the production of silicone products, the precise process control of hot pressing technology is crucial for product quality.   1. Introduction to Hot Pressing Forming Process Hot pressing is a commonly used process in the production of silicone products, which mainly utilizes high temperature and pressure to transform solid silicone raw materials into the desired shape. The process flow is complex and requires precise control of parameters such as temperature, pressure, and time to ensure the quality and performance of the product.   2. Hot pressing process flow Raw material preparation: Select suitable silicone raw materials, usually in the form of milky white blocks. According to product requirements, add vulcanizing agents (ripening agents) and other additives such as colorants, luminescent powders, fluorescent powders, etc. Rubber mixing: Put the prepared raw materials and additives into the rubber mixing machine for mixing, usually for about 30 minutes. This step ensures the uniform mixing of raw materials and additives. Cutting: Cut the blended silicone raw materials into the required size for subsequent hot pressing molding. Awakening material: Place the cut silicone raw material on the awakening material rack and let it sit for a period of time, usually about 8 hours. This step helps bubbles in the raw materials escape, ensuring the compactness of the finished product. Hot pressing molding: Put the awakened silicone raw material into the mold of the hot press vulcanizing machine. Heat the mold to the set temperature, usually between 130 °C and 160 °C. Apply pressure to fill the mold cavity with silicone material. Maintain a certain holding time to allow the silicone to fully cure and form. Sulfurization: During hot pressing, the silicone raw material undergoes a vulcanization reaction to form a stable rubbery substance. Inspection: The molded silicone products need to undergo strict quality inspection, including inspection of appearance, size, performance, and other aspects. Edge removal: Take qualified products out of the mold and remove excess burrs and materials. Post processing: Based on product requirements, perform subsequent processing such as surface spraying, printing, engraving, etc. Final inspection: Conduct final inspection on all processed products to ensure that each product meets quality standards. Packaging: Packaging qualified products and preparing them for shipment.   In summary, through in-depth analysis of the hot pressing process of silicone products, we not only appreciate the complexity and precision of this technology, but also recognize its important role in promoting industry progress. With the continuous development of technology and changes in market demand, the hot pressing molding process will continue to be optimized and upgraded, bringing broader application prospects to the silicone products industry.
