Temperature resistance difference Food grade silicone: A wide range of temperature resistance, can be used between -40 ° C and 200 ° C, suitable for a variety of cooking environments. Ordinary silica gel: the temperature resistance is relatively poor, and the maximum temperature resistance is generally about 150℃. 5. Service life difference Food grade silicone: Because of its pure material, it is not easy to age and has a long service life. Ordinary silica gel: because it contains a certain amount of impurities, it is easy to age and has a relatively short service life. 6. Price difference Food grade silicone: Due to the high cost of raw materials and production, the price is relatively high. Ordinary silica gel: raw materials and production costs are low, and the price is relatively low.   There are obvious differences between food-grade silicone products and ordinary silicone in raw materials, production process, safety, temperature resistance, service life and price. When choosing silicone products, the appropriate silicone material should be selected according to the use and use environment to ensure product quality and personal safety.

It is known in the industry that silicone products manufacturers produce more inventory goods when the weather and environment need to be properly preserved to avoid bad phenomena, the raw materials that are mixed out of the mixer also need to be preserved to make qualified products, and the raw materials of the mixer are basically placed too long will have an impact on the molding process. The product made is not ripe or too brittle phenomenon, there are many friends of the product improper maintenance caused by silicone products aging speed up the phenomenon of reduced service life, how to correctly deal with these two problems?   There are many reasons for the aging phenomenon of silicone products, from the modulation of raw materials to the coordination of silicone products manufacturers vulcans in the hands of customers to maintain the phenomenon, improper maintenance also affects the service life of our silicone products, but in terms of self-maintenance may be appropriate, One advantage of silica gel is that it has a good adsorption force, but the adsorption force is strong, but let it adsorb many small objects in the air, after cleaning agent cleaning appropriate dry to avoid moisture, place can choose a dry place to avoid moisture return phenomenon resulting in aging of silica gel products!   The storage of silicone products also requires certain skills, first of all, the raw materials of vulcanization molding are placed in a dry place. Due to the soft relationship of the material and the heat of mixing, fans can be used to wake up and dry the storage. Generally, placed in high temperature, acid ozone, and humid places will lead to the aging phenomenon of the rubber material to accelerate the performance decline. The molecular dispersion of the rubber material leads to the appearance of dark grain phenomenon of uneven forming color, long-term storage leads to toughness, and the expansion strength decreases. The storage method of the finished product can do a good job of packaging sealed bags to prevent dust from entering, put in a dry place to maintain ventilation to prevent the product from antioxidant decline product deterioration, weather reasons do not place in the outdoor high temperature transparent place, so that the product will appear anaerobic phenomenon.

Small decorative silicone gifts in the gift industry and promotional activities among the scene has become a common gift, according to statistics silicone bracelet wristband consumers account for about 20% of the world, in the entire consumer group, its share is relatively small, but many consumers are more pursuit of perfection, especially foreigners especially like to wear sports silicone bracelets, Do you know the difference between good and bad?   In the early days, the wrist strap is only a primary wristband can only be used for pure silicone, so it is more common, and with the development of smart electronic wristbands, the development of silicone wristbands is faster and faster, at present, many first-line brand electronic products are indispensable to use silicone wristbands as accessories, mainly because of environmental protection and safety, soft and comfortable, but it also has the quality and advantages and disadvantages that you do not know.   Silicone material for the layman it is just a material, should be the same physical properties, but the love of people do not think so, a strap material physical properties may be different in quality and cost will be very different, so you should know more about your silicone bracelet is not like this! Silicone material is divided into ordinary glue and gas phase glue and better medical material and special glue, the price of different rubber materials are different, and the use of ordinary rubber and gas phase glue in the silicone wrist band as common raw materials, ordinary collagen material in the stretch rebound and expansion elongation will be lower, while the gas phase glue in the stretch rebound and material feel better comfort. It can highlight the quality and life of the product. Therefore, the difference between good and bad quality can be mastered on the material, but the premise is that you also need to distinguish the vapor phase glue and ordinary glue material of the silicone wrist strap manufacturer and identify the difference between the two. In addition to the material, that is to work on the silica gel manufacturers and mold county to determine, the first choice is the mold selection and parting line requirements, if it is a first-line brand wrist strap, then the mold and parting line must undoubtedly be done in accordance with the highest standards in the industry, the thinner the mold parting line requirements, the better, the product surface requirements without black spot impurities, feel oil smooth texture can meet industry standards, As far as possible to do a good job, followed by the production quality control of silicone products manufacturers, materials and production model county is a more important link!

The Angle cracking and mold bonding cracking of silicone rubber products seriously trouble the bad phenomenon of products, and the edge cracking phenomenon of products has become the normal in the plate vulcanization process. For this reason, many silicone gifts are prone to edge cracking under the conditions of low hardness, circular arc shape and cylindrical shape. So edge Xiao summarized several causes of edge cracking of silicone rubber products and their solutions! The main reason for the edge explosion is that the silicone rubber gift has a certain arc in the case of low hardness, and there is a certain gap in the middle and inside of the mold when the upper and lower die, which may cause the product to explode. The most common products are circular low-hardness products, so the main reason for this is the error of mold accuracy, CNC correction and tool compensation during mold processing. The fluidity of the raw material is too poor, the nature of the raw material is low hardness, so there will be errors in adding silicone and vinyl silicone oil. Combined with the time temperature and pressure adjustment of the machine itself, the edge of the product bursts and can be adjusted from the machine! The curing speed is not stable, and when the temperature of the machine and the mold is increased or decreased, the product often appears the phenomenon of bursting and bulging. However, when the temperature and time of the machine are adjusted, a cycle is often formed, and the product explosion cannot be permanently solved!   Solution: The gap between the upper and lower molds can be minimized in the mold processing process, and the normal vulcanization production can be maintained by the silicone rubber products manufacturer in the processing process. In the mixing process, the mixing degree of raw materials and vulcanization should be increased, and the raw materials should be mixed evenly as far as possible. In the process of production and processing, to control the weight and placement of the product, the machine temperature should be reduced when the edge is exploded until the product does not crack. However, here, the best way to control the explosive phenomenon in silicone gifts is to maintain the normal operation of the machine, and to keep the product normal and stable in and out of the mold! If the curing time is too long or too short, the product may appear. People who understand the production of silicone know that if the low hardness of silicone rubber products are not controlled well when forming, the edge will crack, which is commonly known as the edge of silicone rubber products. Why low hardness silicone rubber products will have a burst edge? How to deal with the edge of the explosion? Edge Xiao on how to solve the problem of silicone rubber products edge explosion for everyone to sort out and share a few points.   Silicone rubber products The rubber with low hardness (about 30 degrees) is prone to defects such as bubbles during the molding process. If it is the color of the silicone body or the color of the translucent, it is easy to see a lot of white spots on the silicone rubber products. Solution: Increase the temperature of the mold and appropriately increase the temperature of the molding mold. Second, increase the mold temperature, the defects of bubbles and white spots are solved, but the edge of the silicone product begins to crack, that is to say, there is a burst edge. This creates an infinite loop. When the mold temperature increases, the edge will burst, and when the mold temperature decreases, there will be air retention (bubbles) and bad white spots. Solution sheet Reduce the mold temperature of the molding, and extend the curing time if there is bad air retention (bubbles) and white spots. The molding temperature must be greatly reduced until the silicone rubber product does not explode. Don't think that dropping the mold temperature by four or five degrees can solve the problem. Exhaust stroke and frequency must be well controlled, exhaust frequency as small as possible. If possible, exhaust travel should be as short as possible. The amount of vulcanizing agent added can be appropriately reduced. For the low-hardness tridacnID product, there are many factors that cause edge explosion, and some exceptional factors will also cause edge explosion, such as: poor weight control of rubber (too heavy will cause edge explosion, too light will cause lack of material and corners, so control at a reasonable weight will reduce the probability of edge explosion). Secondly, in the long-term production process, it is necessary to properly reduce the mold temperature, so that the mold is kept within a certain temperature range (in the absence of intermittent, the mold temperature should be kept within a certain range). The production process of silicone rubber products is a complex production process, and there are many unused solutions to various problems. For more solutions, please refer to the professional explanation of Dibotridna Rubber Products manufacturer!

Silicone products after deformation how to recover, silicone products because of its excellent elasticity, high and low temperature resistance and good insulation properties, in industrial production and daily life has a wide range of applications. However, in the process of use, silicone products may be deformed due to temperature changes, external force and other reasons. In the face of the deformation of silicone products, how should we solve it?   The following is a solution to the deformation of silicone products: Secondary vulcanization method: For some silicone products, the shape can be restored by secondary vulcanization. This method requires the deformed silicone products to be placed in a vulcanization oven and heated at the appropriate temperature for a period of time to re-vulcanize and restore the original shape. Heating correction method: The deformed silicone products are heated to soften them, and their shape is corrected by manual or mold, and then cooled. Note that the heating temperature should not be too high to avoid damage to silicone products. Force correction method: For slightly deformed silicone products, it can be restored to its original state by applying a certain amount of pressure. This method is suitable for silicone products with certain elasticity. Solvent treatment: Some silicone products can be corrected by soaking in the appropriate solvent to soften them. However, when using this method, it is necessary to ensure that the solvent will not cause adverse reactions to silicone products. Vacuum compound method: The deformed silicone products are put into the vacuum forming machine, and the vacuum suction makes it fit the mold and restore the original shape. Mold re-forming method: For silicone products that are seriously deformed and cannot be recovered by the above methods, you can consider re-using the mold for molding. This method is suitable for deformation during the production process. Material replacement method: If the silicone products are seriously deformed and cannot be recovered by correction, you can consider replacing the new silicone material. Optimize storage and use conditions: In order to prevent the deformation of silicone products during use and storage, exposure to extreme temperatures and humidity should be avoided, while avoiding long-term pressure or stretching. Although the deformation problem of silicone products is common, it can be solved in most cases through reasonable treatment methods. When dealing with the deformation of silicone products, the appropriate solution should be selected according to the specific situation. Understanding and mastering the above solutions can help you better deal with the deformation of silicone products.
