Application of hydraulic press for composite material moulded septic tank

The composite material is mixed with unsaturated polyester resin, thickener, initiator, crosslinking agent, low shrinkage additive, filler, internal release agent and coloring agent to form a resin paste impregnated with chopped fiber roving or glass fiber mat, and Sheet-shaped molded material formed by wrapping polyethylene or polypropylene film on both sides. As a new type of molding compound with rapid development, composite materials have many characteristics: ①Good reproducibility, not affected by the operator and external conditions; ②Convenient operation and handling; ③The operating environment is clean and hygienic, and the working conditions are improved; ④ Good fluidity, can form special-shaped products;
