Cable material made grain machine double order type made grain unit first order for GLS-type high-speed with to double screw Rod extrusion machine, double screw rod can let poly recorded vinyl resin and calcium carbo
nate powder material; DOP plasticizer; additives better of compatible; plastic of; dispersed second order for GLD-series single screw Rod extrusion machine, single screw Rod speed, low temperature, weak shear characteristics phase combined, weaknesses, is today hot sensitive sex, cut sensitive sex material efficient distribution mixed modified sex of preferred models. Most im
portant indicator temperature resistant PVC material. PVC cable material apart from the heat, and temperature rating of the weight loss is also an im
portant indicator. It may indicate a temperature rating of PVC cable materials suitable for the temperature used in the grade. If it loses too much weight then the material temperature additive precipitation evaporation materials easily become hard and brittle and lose their properties. If 90 ℃ PVC TG can o
nly meet the weight requirements of 70 ℃ PVC material, then 90 ℃ not turning 90 degrees centigrade. 200 ° c thermal stability – heat-resistant, high temperature stability time difference, coke charge materials in high temperature processing is easy, easy to squeeze bubbles, poor performance after extrusion of material aging. Specific grty: standard no indicator specified in the uniform, and the quality of the product and cost is closely related to fill is suitable for PVC cable material standard or performance required by customers. Excessive padding in order to reduce costs and will make material mechanical properties such as drop, easily torn, cable, prone to cracking. 70 ° c, 90 c I and 90 ° c ii--the difference between the most im
portant difference between heat aging, weight loss requirements are different. Cable granulating machine high----------spiral mixing machine automatic feeding machine twin screw pelletizing extruder------------------single screw granulator blowing eager head--------------level cyclone seco

PVC料耐温等级最重要的指标。PVC电缆料除热老化外,热失重也是一项重要的温度等级评定指标。它的好坏可说明某温度等级的PVC电缆料中所用的原材料是否适用于该温度等级。若失重量过大则说明材料在使用温度下助剂易析出挥发,材料易变硬变脆而失去原有性能。如果90℃的PVC料热失重只能满足70℃PVC料的失重量要求,那么90℃料就无从谈及90℃。200℃热稳定时间——耐热、耐高温的能力稳定时间差,材料在高温加工时容易产生焦料,挤出时容易产生气泡,材料经过挤出后老化性能严重变差。比重:标准无统一明确规定的指标,它与产品的质量和成本密切相关适宜的填充是为了使PVC电缆料获得标准或客户所要求的性能。过度的填充则是为了降低成本,同时会使材料机械性能等严重下降、容易撕裂、电缆容易开裂。70℃、90℃Ⅰ及90℃Ⅱ的区别——最重要的性能区别为热老化、热失重要求不同。电缆料造粒机;高混机----螺旋自动上料机------双螺杆造粒机----------单螺杆造粒机--------对吹热切机头-----一级旋风分离器---------二级旋风分离器-------加长风冷振动筛------成品料;仓欢迎咨询
