A, food silica is introduced

Food-grade silicone belong to silicone molding, high transparency, linear shrinkage is less than 0.1%, high temperature resistant up to 250 ℃, in a sealed environment heating reduction, complex mode is mainly used in food, candy mold, cake moulds and dimensional requirements equipment is stable, and carbon fiber composite material, the silica gel by FDA food certification.

Second, the food silica gel properties

(1) food grade silicone environmental protection silicone, non-toxic, no smell, high transparency, no yellowing, through the FDA food certification.

(2) soft, good elasticity, resistance to kink deformation.

(3) no crack, long service life, hardy resistance to high temperature.

(4) have a higher resistance to tear strength and superior electrical properties.

5. It has high transparency, tasteless, and the advantages of yellowing, don't spray frost, especially solve the black hose bloom, blue products fade, soft, high resistance to tear, high insulation, wear resistance, high temperature resistant, flame retardant, aging resistance, environmental protection, tensile type, stable performance, etc.

Three, use the food silica gel

Food silicone is widely used in coffee pot, water heaters, bread machine, disinfection cabinet, water dispensers, KaiShuiHu, iron, electric rice cooker, deep fryer, fruit pulp machine, burner, such as mechanical products, machinery, electrical appliances, electrical and other industries. Such as: water dispensers, coffee pot, beauty salon equipment and protective set of lighting products; Fireproof silicone tube: type fire resistant, resistant to high pressure, high temperature resistant and environmental protection, etc. Complex mode is mainly used in food, chocolate mould, candy mold, precision casting, and carbon fiber composite materials, food cake mould, craft ceramics, printing, cloning human organs, household appliances, lighting products, silica gel ice, silicone pacifiers.

Five, food operation method of silica gel

1, stir well to A and B in proportion to the standard, and then into the vacuum machine, vacuum exhaust bubble, general operation time about 10 to 15 minutes.

2, after pouring mold, heat up to 60 ℃ 2-3 hours, cooling and curing can be removed. Such as temperature of 120 ° in just over ten minutes.

3, before use, please take a few experiments, to master the skills, to avoid waste.

Note:

A, this product is a non-dangerous goods, should be sealed storage, and in a cool place, prevent the rain, sunlight exposure.

B, in the process of operation should avoid contact with condensation type silicone rubber vulcanizing agent, also may not cause rubber vulcanization amine compounds, sulfur, phosphorus and some metal salts.

C, and used while operating separate containers, condensation type silicone with unused room temperature silicone tool operation the silica gel.

Six, food silicone common problems

Food-grade silicone is forming silica gel, high temperature resistant up to 250 ℃, which has high transparency, tasteless, and the advantages of yellowing, don't spray frost, especially solve the black hose bloom, blue products fade, soft, high resistance to tear, high insulation, wear resistance, high temperature resistant, flame retardant, aging resistance, environmental protection, tensile type, stable performance, etc. Because food is silica gel after refining and sterilization, through the FDA food certification, can directly when mixed with the food and drug according to the requirement and guarantees the drying of food and food to eat together, and on the human body without any side effects.

Food-grade silicone resin is composed of silicate polycondensation of inorganic polymer gel material, ingredient is SiO2 · nH2O, its content is above 98%, avirulent insipidity, stable chemical performance; Non-toxic, no smell, high transparency, yellowing, this is the characteristics of it, will only be used on food or eat; If the silicone products have peculiar smell is not recommended for use, it is possible that resin as well as the product itself is not caused by pure PP material.

The flavor of the transparent silicone products, general mainly comes from the vulcanizing agent, but not pungent. More than food-grade silicone, there should be no peculiar smell. (color silica gel, a lot of taste may come from the pigment - especially use non-standard paint, sometimes has a pungent taste).
