Secondary vulcanization silicone products for the product
Secondary vulcanization silicone products, with the silica gel products factory specialized terms, also called second shaped silicone products, popular, secondary sulfide also called after cure, the effect of secondary sulfide: silicone rubber using peroxide vulcanizing, peroxide decomposition result in a polymer reaction, generates low molecular compounds, exists in the rubber will affect the mechanical properties of rubber.
Besides silicon after molding, products in the first phase of heating, the crosslink density is not enough, to make its vulcanization reaction to further increase the density of the silicone rubber products.
Pull up strength, resilience, hardness, swelling degree, density, thermal stability is better than a sulfide has great improvement.
Without secondary sulfide, perhaps on the production of silicone products performance affected by certain, can not get better performance of the product.
A sulfide parameters and the parameters of the secondary sulfide may be different, that related to the actual operation!
There are many types of silicone sulfide, with high temperature and room temperature.
According to the high temperature silicone for example, no sulfide is we usually say of raw rubber, before mixing rubber is many additives such as vulcanizing agent, release agent, such as refining and together with gum.
A look can be seen from the appearance.
A torn by hand is broken, it has no elasticity.
If mixing good adhesive in a certain temperature in a certain temperature vulcanization molding can get the silicone products, like we usually see the silicone mobile phone sets, etc.
And a lot of silica gel products factory for secondary sulfide this concept is not very clear, for some special requirements of silicone products, can achieve a certain degree, and can't really reach the product itself is required to stretch or tensile force.
About silicone products factory 'to provide customers reliable high-quality green products.
'Is the production of silicone rubber products factory has always been adhering to the idea.
Company adopts advanced ERP management system, and in accordance with the relevant institutions, laboratories, professional testing company and well-known listed companies have good relations of cooperation, set up its own quality inspection system.
Intermediate inspection is the key to find and solve the major quality problems.
Therefore, maintain the normal operation of the machine, mold good working state, strengthen the operation of the operator and qc personnel skills and quality consciousness training is the key to reduce production bad, is also the enterprise benefit.
