Rubber roller material changes mucosal solution: the use of recycled rubber recycled rubber with plastic rate of powder originally expected to use their own side of the powder mill, the size of a sesame seed size. Now switch to powder plant out of 40 mesh powder. The cheapest use of recycled rubber original, with its own mill about 10 mesh size of sesame seeds powder, non-viscous modulus phenomenon. Current exchange rate of high elastic with plastic recycled plastic, with 40 mesh powder, serious stick-pack gas. We can not produce. IV. Recipe with: 4 kg NR.4 kg SBR.19 kg of recycled rubber. 6 kg powder. Then the rubber sticky heavy, how to solve it? Normal practice is to increase stearic acid and paraffin. But the formula has reached 2.5 parts and 1.5 parts of. 1. good quality recycled rubber. With plastic high rate. Meanwhile sticky roller and die-sticking properties are increased. 2. The change from coarse to fine powder powder. Plastic materials adaptation cohesion increases, rubber toughness better. Causing the exhaust gas is deteriorated. Improvement: 1. Increase the amount of powder, from the original 50, to 100 copies. Test results: the bubble rate of 100%, improving to 30%. 2. Spray a release agent, (formerly the factory without release agents, halo) cell ratio and 30% to 15%. 3. Recommends mold surface treatment, Teflon or plating. (No surface treatment die before actually faint.) Results: spraying a mold release agent, the bubble rate change mold, trench deeper. Exhaust worse. Method: Spray a mold release agent, the bubble rate of 10% -15%. It can not be effectively improved. Add 80 parts coarse powder again. Effect: with a release agent, a radical improvement. Review: stick mode several elements: 1 stick mode of 2. mold surface treatment of materials. 3. The use of the release agent. 4. The compound of osteoporotic. The stick mold, focused on more than 4:00, the whole problem exists. Only makes the problem especially serious. Recommendation: 1 mold surface must be prepared to deal with, such as plating, Teflon. 2. The release agent, it is normal to be used. At the same time, the mold is cleaned regularly, save the mold surface smooth. 3. sticky rubber compound not too, can be used with the point of stearic acid and waxes regulation. If the viscosity is too heavy, then the mold must be treated better. 4. The compound of loose material, the better, the better exhaust.
