    （1）准备工作：着色剂、填充剂分别用80目筛网过筛，并分别加入增塑剂浸透后用三辊研磨机或胶体磨进行研磨，备用。稳定剂、抗氧剂及少量填充剂加入增塑剂中，搅拌成糊状浆料，然后用三辊研磨机或胶体磨研磨，使浆料粒度小于0.050mm，升温到90℃并一直搅拌，备用。PVC树脂用60目筛网过筛。jOy众邦电缆集团公司

Preparations: Colourant and filler are screened with 80 mesh screen respectively, and then soaked with plasticizer and grinded with three-roll grinder or colloid mill for reserve. Stabilizers, antioxidants and a small amount of fillers are added to the plasticizer and stirred into paste slurry. Then the slurry is ground by a three-roll grinder or colloid mill, so that the size of the slurry is less than 0.050 mm, heated to 90 (?) C and stirred all the time for reserve. PVC resin is screened with 60 mesh screen.jOy众邦电缆集团公司

    （2）捏合：高速混合机中通入0.2MPa的蒸汽进行加热，投入PVC树脂，然后缓慢加入研磨好的混合浆，待树脂将增塑剂基本吸收后再加入填充剂、着色剂，物料呈膨胀疏松粉末时卸料，此时料温在110℃左右。全过程约需要5～10分钟。jOy众邦电缆集团公司

Kneading: High-speed mixer with 0.2 MPa steam for heating, put into the PVC resin, and then slowly add the grinded mixture slurry, after the resin will be absorbed by the plasticizer, then add filler, colorant, when the material is expanded loose powder unloading, at this time the material temperature is about 110 degrees Celsius. The whole process takes about 5 to 10 minutes.jOy众邦电缆集团公司

    （3）密炼：蒸汽压力0.3～0.4MPa，压缩空气压力0.5MPa，密炼时间3～5分钟，上顶拴抬起次数2～3次，物料密炼成团状小块，无粉料时卸料。jOy众邦电缆集团公司
Internal mixing: steam pressure 0.3-0.4 MPa, compressed air pressure 0.5 MPa, mixing time 3-5 minutes, lifting times 2-3 times, the material is compacted into small pieces, unloading without powder.jOy众邦电缆集团公司

    （4） 双辊开炼：蒸汽压力0.4～0.5MPa，辊温160～170℃（绝缘料温度宜高些）至料完全塑化均匀后，以3mm厚度出片，所出料片应塑化均匀，韧而光洁、无生料。jOy众邦电缆集团公司
Twin-roll smelting: steam pressure 0.4-0.5 MPa, roll temperature 160-170 C (insulating material temperature should be higher) until the material is completely plasticized uniformly, and the sheet is 3 mm thick. The discharged sheet should be plasticized uniformly, tough and smooth, without raw material.jOy众邦电缆集团公司

    （5）冷却：采用逆流浸没式水冷却槽，鼓风机除去料片上粘着的水分。jOy众邦电缆集团公司
Cooling: Use countercurrent immersion water cooling tank, blower to remove the moisture adhering to the material sheet.jOy众邦电缆集团公司
