Plaster silicone mold silicone rubber | silicone mold plaster

 Plaster silicone mold silicone rubber | silicone mold plaster: 1, the appearance of a liquid silicone mold flow, A component is silica, component B is the curing agent. 2, liquid silicone is a relatively high temperature vulcanized silicone rubber is solid, which is a liquid adhesive, with good fluidity, curing faster, safer environment, can fully meet food grade requirements. According to the molecular structure contained in the functional group (ie, crosslink) position, often the liquid rubber having a functional group is divided into two categories: one is the functional group at both ends of the molecular structure called telechelic liquid rubber; the other is reactive functional groups in the main chain were randomly distributed within the so-called molecular structure with functional groups, known as non-telechelic liquid rubber. 3, according to the hardness of the cured silicone size after distinction are: 0 degrees silicone molds, silicone mold 5 degrees, 10 degrees silicone molds, silicone molds 15 degrees, 20 degrees silicone molds, silicone molds 25 degrees, 30 degrees, silicone molds, silicone mold 40 degrees 50 degree silicone molds, silicone mold 60 degrees. (According to the size of the product is copied to choose the relative hardness of the silicone mold.) Plaster silicone mold silicone rubber | silicone mold plaster characteristics: liquid silicone mold is excellent in transparency, tear strength, resilience, anti-yellowing, thermal stability, water permeability, heat aging resistance and weather resistance, while moderate viscosity, easy operation, high product transparency, can be seen filling the casting mold material for bubbles and other defects, linear shrinkage ≤0.3% , fine size patterns can replicate sophisticated products. Plaster silicone mold silicone rubber | silicone mold plaster applications: plaster line, shaped plaster, toy and gift industry, craft gift industry, furniture decoration industry, people copy, architectural decoration industry, resin handicraft industry, unsaturated resin crafts industry, candles, plastic toy industry, gift stationery industry, plaster craft industry, mold manufacturing industry, Boli industrial, simulation of animals and plants sculpture, Buddhist carvings and other handicrafts industry products copied and mold making. Plaster silicone mold silicone rubber | silicone mold plaster line method of operation: 1, the ratio of silicone and curing agent stir (add 2-3% curing agent best); Example: Take 1000 g of silica gel, 30 g of a curing agent ( NOTE: silicone and curing agent must stir, if not stir, silicone mold appears incomplete curing phenomenon, dried and cured silicone uneven situation will affect the life of the silicone mold and turning model number, and even the silicone molds retirement, can not use 2, vacuum exhaust bubble process: silica gel and curing agent Stir shall be evacuated rows of bubbles (-0.1MPa under pressure); vacuum discharge bulbs should not be too long time, under normal circumstances, no more than ten minutes, vacuum too long, cured silicone may be ahead, resulting in a crosslinking reaction, into a piece of silicone can not be painted or perfusion. discharge bulbs incomplete will directly affect the life of the silicone mold 3, the process of filling the mold or brush mode operation: The row over the bubbles evacuated silica gel, brushing or perfusion way down in the product above (Note: the product or model to be replicated before the fall of silica gel must be cleaned and fight Good release agent). then put silicone in the product above brushing, brushing must be uniform, 30 minutes after pasting a layer of gauze to increase the silica fiber sheeting, strength and tension. then brushing a layer of silica gel, and then paste a layer of gauze fiber sheeting, so the two will be able to do so later, open up the silicone mold turning model of life and to improve the lot number of a relative, you can save costs and improve efficiency 4, silicone outer mold making: General methods and materials used is mold around with plastic sheet or boarded up, a cabinet filled with plaster to mold it, another way of using the resin brushing, brushing a layer of resin paste layer on glass fiber cloth, then brushing then paste, repeated two or three can be done a distinction between the outer mold mold mold filling and brush modes: operation method A, mold filling or perfusion mode: mold filling or perfusion mode, it is used to compare smooth or simple product, there is no parting line saving time and labor, B, fragmentation mold or sheet molding method of operation: first before brushing your product or model to be copied brushing a layer of release agent, or release agent, rear) wait 30 minutes, will be attached to the surface layer of gauze or fiberglass sheeting to increase the intensity, and then brushing the second layer of silica gel silica gel drying, do the outer mold, the outer mold can use plaster or resin material.
