PVC yomwe imadziwika kuti polyvinyl chloride, kutentha kwake kwa viscosity otaya ndi kutentha kwapang'onopang'ono kuli pafupi kwambiri, kotero ndikosavuta pakuwonongeka kwamitundu yosiyanasiyana, motero kutaya ntchito.Choncho, m'pofunika kuwonjezera kutentha stabilizer ndi lubricant mu chiphunzitso cha PVC osakaniza, wakale bwino kutentha bata, yotsirizira amachepetsa kukangana pakati PVC maselo unyolo, ndi defilming mphamvu pakati PVC Sungunulani ndi zitsulo, kusintha mayiko PVC muzinthu zosiyanasiyana.Sera ya pe ndi oxidized polyethylene sera ndi mafuta omwe amapezeka mu PVC.

Pokonza PVC, palibe kusungunuka koyera, tinthu tating'onoting'ono (pafupifupi 100μm, tokhala ndi tinthu tating'onoting'ono tomwe timayambira) timagawika kukhala mipira yaying'ono (pafupifupi 1μm) ndi timadontho tating'onoting'ono (pafupifupi 100nm) pakuchita kumeta ubweya wamafuta ndi makina. njirayi nthawi zambiri amatchedwa gelation kapena pulasitiki.Kuti mukwaniritse bwino makina, katundu pamwamba ndi processability, mlingo wa gelation pakati 70% ndi 85% ndi yoyenera.Njira ya gelation imatha kuchedwa kapena kufulumizitsidwa ndi kusankha koyenera kwa sera ya polyethylene.Pambuyo kusungunuka, ndi homogeneous polyethylene sera alipo pakati particles woyamba kuti kapena tinatake tozungulira, amene amachepetsa mikangano mphamvu pakati pa tinthu tating'ono ting'ono kapena tinatake tozungulira, motero kuchepetsa frictional kutentha kusungunula, kuchedwa plasticization wa PVC, ndi nthawi yomweyo, kukhazikika kwamafuta a PVC kunasinthidwanso.Sera yokhala ndi okosijeni ya polyethylene imakhala yogwirizana ndi PVC, imatha kumamatira pamwamba pa tinatake tozungulira, kuonjezera kukhuthala kwamphamvu, ndipo imakhala ndi ikukonzekera bwino pakhalidwe la gelation, kuchepetsa mikangano pakati pa kusungunula ndi zida zopangira zida zabwino. The processing wa PVC, makamaka mandala PVC (organotin stabilizer) filimu, kuwonjezera kuchuluka kwa oxidized polyethylene sera osati masewero amasulidwe zabwino kwambiri, komanso sikuchepetsa kuwonekera.

Pakali pano, kuwonjezera kupanga pe sera ndiwothiridwa ndi polyethylene seramu PVC, sera ya parafini, feto phula ndi phula lopangidwa ndi mankhwala amagwiritsidwanso ntchito kwambiri ndipo amafunikanso kufananizidwa mosinthasintha malinga ndi momwe angagwiritsire ntchito ma terminal, Mwachitsanzo, sera ya parafini yotsika imatha kugwira ntchito yopaka mafuta koyambirira, posungunuka. sera ya polyethylene, feto phula amatha kugwira ntchito yapakati pa nthawi yopaka mafuta, phula losungunuka la oxidized polyethylene sera limatha kutenga gawo lopaka mafuta mochedwa.Ena kutentha zosagwira mafuta ochepa monga parafini sera, mafuta acid esters, etc. , zosavuta extrusion mankhwala kufa, anagubuduza kuzirala wodzigudubuza mafunsidwe.Zinthu izi pamtunda wa zinthu zomaliza, komanso malo ogwira ntchito ogwira ntchito pa malo, kupanga kudzakhala ndi zotsatira zoipa.Komanso, lubricant limodzi PVC ngakhale ndi mkulu kwambiri, ngati ntchito gulu lubricant phukusi, zigawo zosiyanasiyana za wina ndi mzake zosemphana, anachita, n'zosavuta kutsogolera psinjika.Choncho, malinga ndi ntchito mankhwala monga ngati kufunika kusindikiza, kupopera mbewu mankhwalawa, kusankha khola khalidwe, kutentha kukana lubricant, kwa kupanga yosalala ndi kusintha khalidwe mankhwala n'kofunika kwambiri.
