PC加工方法
PC可以是注塑、挤出、成型、吹塑、热成型、印刷、粘合、涂层和机加工。最重要的加工方法是注射成型。成型前必须进行预干燥，含水率应小于0.02%。在高温下处理微量水分会导致产品产生白色混浊、银丝和气泡。PC在室温下具有相当强的强制高弹性变形能力。冲击韧性高，可冷弯成型、冷拔、冷轧等。挤出用PC的分子量应大于30000。应使用逐渐压缩的螺钉，长径比为1:18~24，压缩比为1:2.5。可采用挤出吹塑、注射吹塑、注射拉伸吹塑。高质量，高透明的瓶子。PC合金有很多种。为了改善PC的高熔体粘度（可加工性）和产品的易应力开裂，PC与不同的聚合物形成合金或混合物以改善材料性能

Product Details
PC processing method
PC can be injection molding, extrusion, molding, blow molding, thermoforming, printing, bonding, coating and machining. The most important processing method is injection molding. It must be pre-dried before molding, and the moisture content should be less than 0.02%. The processing of trace moisture at high temperature will cause the product to produce white turbid color, silver wire and bubbles. PC has considerable forced high elastic deformation ability at room temperature. The impact toughness is high, so it can be cold-formed, cold-drawn, cold-rolled, etc. The molecular weight of PC for extrusion should be greater than 30,000. Gradually compressed screws should be used, with a length-to-diameter ratio of 1:18~24 and a compression ratio of 1:2.5. Extrusion blow molding, injection-blow, injection-stretch-blow molding can be used. High quality, highly transparent bottle. There are many types of PC alloys. In order to improve the high melt viscosity of PC (processability) and easy stress cracking of products, PC forms alloys or blends with different polymers to improve material properties.
PC processing method
Specifically, PC/ABS alloy, PC/ASA alloy, PC/PBT alloy, PC/PET alloy, PC/PET/elastomer blend, PC/MBS blend, PC/PTFE alloy, PC/PA alloy, etc., Advantages have two material performance advantages and reduce costs. For example, in PC/ABS alloys, PC mainly contributes high heat resistance, better toughness and impact strength, high strength and flame retardancy, and ABS can improve formability. Apparent quality, reduce density.
