ntchito

The zikuchokera waukulu PVC chingwe chuma makamaka zikuphatikizapo:polyvinyl chloride utomoni, dioctyl phthalate, stabilizer, plasticizer, inorganic filler, filler, lubricant, antioxidant, colorant, etc., zokonzedwa ndi kusakaniza ndi kukanda ndi extrusion.

Zomwe zili ndi pulasitiki nthawi zambiri zimakhala pakati pa 50PHR ndi 60PHR.Nthawi zambiri sankhani kukana kutentha ndi ntchito yamagetsi yamagetsi yapulasitiki yabwino kwambiri kuti muwonjezeke kukana kutentha kumatha kuwonjezeredwa ku trioctyl metapentriacid.Mitundu yosiyanasiyana ya mapulasitiki omwe amagwiritsidwa ntchito palimodzi amakhala ndi zotsatira zabwino kwambiri.M'malo mwake, mapulasitiki opangira zida za PVC amagwiritsidwanso ntchito limodzi.PVC chingwe chuma ndi kutchinjiriza amphamvu akhoza kusankha mankwala ester monga wothandizila chachikulu, ndi benzoate ester monga wothandizila waukulu ndi oyenera kalasi wamba.Kukaniza kutentha ndi kukana kosasunthika kwa plasticizer ndizofunikira kwambiri pakutentha kwamphamvu kwazinthu zamagetsi.
