PC加工要注意哪些事项?
PC塑胶原料的水率较大,加工前一定要预热干燥,纯PC干燥120℃,改性PC一般用110℃温度干燥4小时以上。干燥时间不能超过10小时。一般可用对空挤出法判断干燥是否足够。再生料的使用比例可达20%。在某些情况下,可的使用再生料,实际份量要视制品的品质要求而定。再生料不能同时混合不同的色粒,否则会严重损坏成品的性质。
Because of the cost and other reasons, the PC plastic products of Huayun Plastics Company have to be made of modified materials, especially electrical products, and the fire-proof property must be increased, injection Molding Machine plasticizing system requirements are mixed well, corrosion-resistant, conventional plasticizing screw difficult to do, in the purchase, must be explained in advance. Mold and gate design, common mold temperature is 80-100 °C, add glass fiber is 100-130 °C, small products can use needle gate, gate depth should be 70% of the thick part, other gates have ring and rectangular. The bigger the gate, the better, to reduce the plastic was excessive shear and cause defects. The depth of the vent hole should be less than 0.03-0.06 mm, the runner should be as short as possible and round, and the declination of demoulding should be about 30′-1. Melt temperature can be used to determine the air injection processing temperature. The processing temperature of General PC plastics is 270-320 °C, some modified or low molecular weight PC plastics raw materials are 230-270 °C.
