Some products can be directly used after the molding process, and some products also need to undergo secondary vulcanization (also called secondary sulfur). In fact, we look like a good product from the naked eye after molding, can also be used normally, why also secondary vulcanization? First of all, to be sure, not all need silica gel secondary vulcanization silicone rubber products, only depending on the formulation of raw materials, some of them are a molding can directly, but some special materials such as fluorine rubber products, some of the EPDM is the need for secondary vulcanization silicone rubber products, that's because the first of these materials in a sulfide, The peroxides in the polymer reaction will decompose, produce some low molecular compounds (such as benzene, benzoic acid, etc.), these low molecular compounds mixed in rubber will reduce the mechanical properties of silicone rubber, reduced life, but also toxic. This is very unfavorable for silicone kitchen utensils, so silicon rubber products J manufacturers commonly use secondary vulcanization to decompose and volatilize the low molecular compounds. Second, at the end of a vulcanization, silica gel molecules may not be fully cross-linked (vulcanization is not sufficient), silicone rubber secondary vulcanization can make its vulcanization more fully, more uniform, so as to improve the mechanical properties and durability of rubber. Third, the secondary vulcanization of silica gel, such as a large number of EPD silicone rubber products used in cars after secondary vulcanization can remove odor, improve the comfort of car occupants. Fourth, silica gel products manufacturers wholesale in order to reduce costs, improve productivity, often shorten the first silica gel vulcanization time, and then in the extension of the second vulcanization time, to ensure that the product is fully vulcanized at the same time, but also to improve their competitiveness.

Causes the deformation of silica gel products? Found these three easy to cause the deformation of silica gel products. 1,Long-term immobility leads to permanent deformation. It is easy to deform products with hard material under high pressure when used for a long time. 2,the influence of tensile rate, the product of hard softness to decide, general silicone rubber of the highest winning percentage can reach 300% to 600% (more soft material), but in the use process of overstretch will directly lead to deformation and loss of permanent deformation of tensile strength, so you should don't overdo it stretched in the using process, regardless of industrial products, supplies or silicone accessories are the same. 3,the influence of temperature occasions, a humid place, when silicone rubber products work, in the humid high temperature situation in the process of use, tensile gradually deformation, but with the temperature adaptation and decline will also lead to silicone products appear slight deformation. So whether it is in the industrial application of accessories or sealing products, in addition to people think that try not to let silica gel products for a long time.

In the silica gel product factory, color mixing is a basic work that cannot be separated from, and it is also a very technical work. We have met many people who would confuse color mixing with color matching. Color mixing means to adjust the source color to the color that the customer wants or is close to. And color matching needs to be combined or matched according to the actual situation of the product into a very good-looking product, through the use of different color master or multiple color master collocation, matching into the required color we will usually record for next use. In silicone products factory, the color is relatively simple, just need to adjust the effect of customer needs, but also need to know about color knowledge, technical barriers to samsung around, and the color need to start from scratch to formulate formula and adjust the color, the color is on the basis of the original formula to add and subtract masterbatch and component, make its closest to the target color and summed up the record good formula. Silicone products more and more with the use of color, collocation of color is also more and more, this requires the colorist and colourist undertakes collocation, but in general factory inside the colorist and colourist is a person to operate, in the big factories are generally of division of labor cooperation, so small factories including color and color matching are all have a lot of experienced technical personnel, And every factory must be a skilled hand. Speed along with the development of the silicone industry, the original primary colors already cannot satisfy the needs of customers at the same time, also need a massive increase in the market product novelty, usually the colorist and color need to constantly deal with masterbatch, r&d and product types of different color is tie-in, can make more products by silicone material show in front of the user, Such as the previous printing done to silicone can not be done, can also be realized.

With the continuous development of silica gel industry, silica gel process is constantly improving, silica gel mold processing factory sometimes in order to meet the requirements of customers, to ensure the quality of silica gel products, but also to achieve high gloss of the surface of silica gel products, so how to achieve the surface gloss of silica gel products? The high gloss of the surface of silica gel products is the form of high-quality silica gel products, and the high gloss is made of the mold of highly polished silica gel products. So how should we ensure the quality of the mold? First, to ensure that in the manufacture of molds according to the size of the product to choose the right hardness silica gel. In this way, silica gel products can have better gloss and more beautiful. Two, silicone oil can not be added to the gel, because the greater the amount of silicone oil added, the softer the mold, the lower the tensile force and tearing strength, the silicone will not last, the service life will be reduced. Gloss on the surface of silica gel products all want to better, sometimes the silicone mold processing factory before the processing technology of silica gel, should first consider the customer's requirements, choose accurate processing technology, while the method above is more expensive but can ensure the process of silica gel products is smooth, no nonporous surface strengthened pillar. Silicone itself does not use any treatment as a non-stick thing, but it is recommended to adhere to the butter and fuel spread on the baking sheet is good.

In the manufacturing steps of silica gel products, sometimes the manufactured goods will occur viscera tone is never that and water ripple effect, this effect is collectively known as "dark mark", which is a bad phenomenon. Why do silicone rubber products appear dark marks? 1. The temperature resistance of color paste is very little, resulting in water ripple effect on the surface of silicone rubber products. Textile forming cause of the dark mark rubber, its are tonal are replaced by two more than color paste distribution and thus, if a few kinds of color paste and heat-resistant effectiveness lies far away, will cause to the forming of low temperature and some color paste didn't fade, thus some little color paste due to thermal efficiency and fade, the goods after forming the surface water ripple effect. 2, forming concentration less than color paste temperature area fade, resulting in silicone rubber commodity surface tone is not the same. 3, the discharge method is not appropriate and the different types of rubber mixed together to form the surface color of silicone rubber products is not the same.  

1, safety performance silica is the main component of silica, chemical stability, non-toxic. 2, silica gel has a strong adsorption capacity, can produce drying effect on human skin. If silicone gets into the eye, rinse with plenty of water and seek medical attention as soon as possible. 3, blue silica gel contains a small amount of cobalt chloride, toxic, should avoid food contact and inhalation mouth, such as poisoning should immediately seek medical treatment. Silica gel is a kind of highly active adsorption material, belongs to the amorphous substance, its chemical molecular formula is mSiO2·nH2O. Insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any substance. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.

In the processing of silica gel products, the most troublesome process is to remove the edge, especially the products produced by the molding process, remove the edge to make people crazy. So what are the causes of rough edges?   1. The curing temperature is too high or the curing time is too long Silica gel products in the molding process, once the temperature is too high or vulcanization time is too long, it will cause the product molding after numbness or brittle, whether numb or brittle, will have a great impact on the side. 2. The curing temperature is too low and the curing time is too short Silica gel products are not completely vulcanized when the elasticity is strong, so it is not easy to separate the raw edge and the product when removing the edge, so it is generally necessary to use scissors to repair the edge. 3. Mould self-disassembly design is unreasonable, processing quality is not up to standard or mould wear time is too long In the design of the mold, the mold design is not reasonable, manufacturing the mold since the opening is not sharp, resulting in the product is difficult to remove the edge after forming. In addition, silicone products mold wear or sandblasting times too much will also affect its self-disassembly performance. 4. The forming thickness is too large In the molding process as long as the size meets the requirements, try to do thin, ruler, accurate material. 5. Silica gel raw material problem There is a problem with the rubber link, the quality of the rubber material is poor, there is a lack of tearing strength, poor toughness, and easy to fracture when forming.

For silicon veins 6 hanging sticky dust actually is the chief drawback of silicone material, no matter in any environment will appear this kind of circumstance, so a lot of friends love silicone products gradually in a little because it no longer love, for the silicone products manufacturer make silicone products particularly big cases to absorb dust will also take corresponding measures, For example, the use of antistatic glue raw materials, negative ions, but for the majority of consumers is very troublesome, so you can first understand its adsorption force can be properly prevented! Silica gel mainly physical adsorption force, where even without moving around the cilia, also gradually as the reaction of the electrostatic dust sticky on the surface of the product, because the silicone raw materials belong to the anode sex, to do all kinds of chemical auxiliary materials have strong adsorption reaction to other polar substance, in order to enhance the silicone adsorption force, should increase active type structure unit of adsorbent. Therefore, if the calcination of silica gel makes it completely dehydrated, the silica hydroxyl group of silica gel is completely destroyed and reduced or even no adsorption capacity; If a large amount of water is added to silica gel, its adsorption force will also be reduced, because the silicon hydroxyl group forms too many hydrogen bonds with water and thus reduces its active type ratio. Secondly for hardness higher product and without the influence of the adsorption of dust and debris, for low hardness products adopt electrostatic rubber production will not have a sticky dust, the phenomenon for silicone products adsorption problem for silicone rubber products manufacturers can be baked to keep products belong to remove certain electrostatic drying, in spraying oil to prevent feel sticky dust, Feel oil is an oily substance whose main function is to increase the smoothness of silica gel surface appearance and maintain dustproof effect. For consumer friends, you can buy white electric oil to wipe properly, and use dust-free cloth to stick alcohol can also remove the dust on the appearance!  

Silica gel keys are easy to absorb dust under normal circumstances, so in the production process, we will spray a thin layer of feel oil on the surface of silica gel keys, which can prevent dust and make the feel better. We think that the main effect of oil injection is to improve the feel and beauty of the product, so that the product can maintain a smoother, more three-dimensional feeling, and how should we choose which kind of oil injection?   There are three different ways to handle silicone key oil injection: First, spray color oil: Spray color oil is sprayed on the surface of the silicone keys with a layer of visible ink, and the color can be adjusted according to the customer's demand for goods. Two, spray extinction: Extinction ink is a kind of fog surface feel ink, its characteristics are similar to PU ink, but the spray extinction ink will make the silica gel button appearance of fog surface, and can spray the effect of scrub, feel is smoother than! Three, spray PU: PU refers to a kind of ink, it has the characteristics of strong adhesion, wear resistance, good transparency, etc., sprayed PU silicone key feel is also very good, very wear-resistant, is also a common silicone key injection oil. The above three are commonly known as the "oil injection silicone key", and some people say spraying, spray painting.

Gaskets are often used in every field, but different materials are used in different environments. Silica gel material has become a common gasket tool, which is often used in many aspects, such as padding thickness, shock absorption and buffering, beautiful decoration, etc. And for silicone material made of gaskets do not understand you will not be difficult to understand it enough to achieve the effect you want and want the effect, in this is the most key!   More extensive and silicone gasket reference with our application by the different environment can adopt different production processes, currently on the market a lot of silicone material can use solid silica gel of silica gel and forms two kinds of different materials, different difference lies in different hardness, transparency, softness, and we often use the silicone gasket hardness requirements have not been very low, Therefore, solid silica gel has become the first material chosen by consumers. Solid transparent silica gel belongs to hot vulcanized silicone rubber. The unsolidified form is essentially an immobile solid substance. It is mainly used to manufacture all kinds of silicone rubber products, silicone accessories, silicone daily necessities and so on. The degree of flexibility is generally between 30-80 degrees. The advantages of high toughness, high transparency and environmental protection are so that it has been selected by many markets.   In this aspect of material performance must be a lot of friends should understand. Colorless, tasteless, non-toxic environmental protection, high density, good tensile, wide temperature range can be keep softness for a long time, due to the good performance can be placed in the disadvantage of environment using for a long time, so for the silicone gasket used are closely related to the speed of the environment and fixed-line, in the process of silica gel products manufacturers processing appropriate adjust the curing time may change a product's dielectric properties, If the fixed-line speed is too long, the softness of the product will be affected. If the product is too brittle, the appearance will be torn, the toughness will be reduced, and the aging will be accelerated. Therefore, the quality of the silicone gasket and the material of the body can be controlled in the processing process.
