Silicone rubber is a kind of highly active adsorption material, is an amorphous substance, 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. Silica gel products have cold resistance of -40 °, high temperature resistance of 240°; Soft and easy to fold; Can be recycled; Non-toxic tasteless environmental health; Easy to clean; Good elasticity, durability and other advantages. Introduction to production process: 1.The preparation
Calculate the weight of materials required for the production of this batch of orders according to the product BOM. Then calculate the weight of raw materials, color paste, vulcanizing agent and other raw materials according to the formula of raw materials. Prepare all kinds of raw materials required according to the calculation result。 2. Rubber mixing
In raw materials, color paste, vulcanizing agent and other raw materials are ready, can not be directly used for vulcanization molding, need to use the machine to stir these raw materials evenly, this process is mixing, also known as mixing. The purpose of the silica gel product is to mix the vulcanizing agent into the raw material, so that it meets the necessary conditions for molding, and according to the color formula to add the corresponding color paste will be the rubber coloring. 3. The cutting material
All kinds of raw materials after mixing, can be used for molding. But at this time mixing uniform rubber shape is a large volume, such as directly used for vulcanization molding, after mixing rubber, but also need to cut according to the product process book machine will be cut into silica gel products molding required size and weight, in the cutting process to pay special attention to weight and size control。 4. Hot pressing molding
Wake up to the time, the cut rubber in the hot press vulcanization machine mold inside, heating, exhaust, pressure, molding. Before this process, it is necessary to heat the mold of the vulcanizing machine for a few hours in advance, and then put the rubber into the mold. After forming, it is necessary to take out the rubber and the mold after cooling. In this process, staff need to watch carefully at any time to ensure that the product does not make mistakes. 5. Inspect and trim edges
After forming the product for product inspection, whether there is dirty, whether there is a lack of edge, lack of material, the product is not ripe, the product is broken and other bad conditions, the defective product will be selected out of the place (the defective product can only be treated as waste, not in the second use) will pass the rough edge of the product clean. 1.Check the packaging and warehousing
Package and store qualified products according to customer's requirements.
