PVC yas granules yog granules npaj los ntawm kev sib tov, kneading thiab extrusion nrog polyvinyl chloride ua lub hauv paus cob, ntxiv stabilizers, plasticizers thiab inorganic fillers xws li calcium carbonate, additives thiab lubricants. Cov yam ntxwv cuam tshuam rau qhov ci ntawm PVC yas pellets cable cov khoom siv: qhov qis dua ntawm polymerization ntawm PVC, qhov ci ntsa iab; lub finer cov calcium carbonate particle loj, lub brighter nto; plasticizer: qhov ncaj thiab ntev ntawm cov saw molecular, lub ci dua; Cov nrawm dua kuj ci dua; thev naus laus zis, cov uas muaj qhov kub siab extrusion yog ci dua li cov uas tsis muaj qhov kub thiab txias, thiab cov nyhuv zoo sib xyaw yog ci dua li cov uas tsis zoo sib xyaw.
