Secret method of making a shoe mold silicone

Condensation-type two-component RTV silicone rubber vulcanization mechanism is mainly de-alcohol condensation crosslinking, crosslinking amine condensation decarboxylation, dehydrogenation condensation crosslinking, dehydration condensation crosslinking four processes. 　　Condensation-type silicone characteristics Xiemo 　　Condensation is a prototype shoe mold silicone mold with condensation-type two-component RTV silicone rubber, RTV silicone rubber process is the use of off-type, low shrinkage, easy vulcanization molding, heat aging characteristics of the development of a class of products. Not only can be used in the shoe industry, in electronics, electrical appliances, machinery, instruments, toy industry and other industries.   　　So the use of these products can be roughly divided into general grade for simple shapes, complex shapes for split Gaussian intensity grade, synthetic leather surface patterns grades three kinds of Indian film produced variety series. There are requirements for basic performance, good liquidity, low linear shrinkage, anti-pollution, long life. 　　So what is the plastic shoe mold making methods? 　　In general, the condensation-type shoe mold silicone mold with a two-component RTV silicone rubber condensation can start by making the following steps: 　　1 cardboard frame, made ??of plywood or aluminum bottom stripping machine coated with glass or plastic plate; 　　Prototype 2 will be placed on the bottom of the glass or plastic plate; 　　3 prepared base and curing agent according to the proportion of good weighing, mixing and vacuum discharge bulbs processing; 　　4 colloids backward prototype hybrid surface, the surface can not have bubbles, but also to all buried, and the thickness of one centimeter more than the prototype; 　　5 at room temperature curing, after curing is successful, the frame upside down, remove the prototype from the lower frame, this time the condensation will be made of plastic shoe mold. 　　Note: The time Xiemo glue to cure at room temperature to grasp depending on the species, usually within 8-24 hours; precision in order to improve their life and to heat curing reaction at 60 °C to 80 °C in the vicinity of the colloidal Care 4-6 hours. 　　Shenzhen Hongye Jie Silicone Factory professional development, production and condensation-type silicone shoe mold, shoe mold silicone condensation, condensation-type shoe mold silicone and other silicone products, welcome customers and dealers to negotiate, expert advice hotline :400 -779- 4008, you can also send us an email info@szrl.net.
