Dzina lonse la PVC ndi PVC.Kutentha kwake kothamanga kwa viscosity kuli pafupi kwambiri ndi kutentha kwachiwonongeko, kotero n'zosavuta kuchitika mitundu yosiyanasiyana ya zowonongeka panthawi yokonza, motero kutaya ntchito yogwiritsira ntchito.Choncho, kutentha stabilizer ndi lubricant ayenera kuwonjezeredwa chilinganizo cha PVC kusakaniza zosakaniza.Yoyamba imapangitsa kukhazikika kwake kwamafuta, pomwe yotsirizirayi imachepetsa kukangana pakati pa ma PVC ma cell, komanso kutulutsa mphamvu pakati pa PVC kusungunula ndi chitsulo, kuti ipititse patsogolo kusinthika kwa PVC kukhala zinthu zosiyanasiyana. Polyethylene sera ndi wothiridwa ndi polyethylene sera ndi mafuta omwe amapezeka mu PVC.

Pa processing wa PVC, palibe koyera kusungunula, kokha yachiwiri particles (100 μ M, amene wapangidwa ndi particles chachikulu ndi tinatake tozungulira) anagawa mu mipira yaing'ono (1 μ M kapena kotero), ndiyeno anagawa tinatake tozungulira (100nm).Njirayi imatchedwa gel kapena pulasitiki.Kuti mukwaniritse bwino makina, katundu pamwamba ndi processability, mlingo wa gel osakaniza ndi yoyenera pakati pa 70% ndi 85%.Kusankhidwa koyenera kwa sera ya polyethylene kumatha kuchedwetsa kapena kufulumizitsa gel osakaniza.Sera ya homopoly polyethylene ilipo pakati pa tinthu tating'onoting'ono tomwe timayambira kapena tinthu tating'onoting'ono tikasungunuka, kuchepetsa kukangana pakati pa tinthu tating'onoting'ono kapena tinatake tozungulira, motero kumachepetsa mikangano yotentha yosungunuka, kuchedwetsa kuyika kwa PVC, ndikuwongolera kukhazikika kwamafuta a PVC.Theop waxali ndi kuyanjana kwina kwa PVC, komwe kumatha kumangiriza pamwamba pa tinthu tating'onoting'ono, kukulitsa kusungunuka kwamphamvu, ndikulimbikitsa pang'ono gel osakaniza;

Ntchito yake ina yayikulu ndikupanga a filimu pa PVC Sungunulani ndi zitsulo pamwamba kuchepetsa kukangana pakati pa Sungunulani ndi zida processing.Ndiwotulutsa bwino nkhungu pokonza PVC, makamaka mufilimu yowonekera ya PVC (organic tini stabilizer).Kuonjezera kuchuluka koyenera kwa sera ya oxidized polyethylene sikungangokwaniritsa kumasulidwa kwa nkhungu, komanso sikuchepetsa kuwonekera.

Pakali pano, kuwonjezera kupangapa wax ndi ope sera mu PVC, sera ya parafini, Fischer Tropsch sera ndi-product sera amagwiritsidwanso ntchito kwambiri, zomwe zimafunikanso kusinthasintha molingana ndi kugwiritsa ntchito terminal.Mwachitsanzo, parafini yotsika kwambiri imatha kuthandizira kudzoza koyambirira, sera yapakati yosungunuka ya polyethylene ndi Fischer Tropsch sera imathandizira pakupaka mafuta apakati, ndipo sera yosungunuka kwambiri ya oxidized polyethylene imatha kupangitsa kuti mafuta azikhala mochedwa.Mafuta ena omwe ali ndi kukana kutentha pang'ono, monga sera ya parafini ndi ester yamafuta amafuta, ndi osavuta kuyika pamutu wa zinthu zomwe zatulutsidwa ndi mpukutu woziziritsa wa filimu ya calendering.Zinthu izi zitha kukhala ndi zotsatira zoyipa pamachitidwe apamwamba azinthu zomaliza, komanso malo ogwirira ntchito komanso kupanga kwa ogwira ntchito pamalowo.

Kuphatikiza apo, kuphatikiza kwamafuta amodzi mu PVC ndikokwera kwambiri.Ngati phukusi lamafuta ophatikizika likugwiritsidwa ntchito, zigawo zosiyanasiyana sizigwirizana ndipo zimayenderana, zomwe ndizosavuta kuyambitsa kupatukana.Choncho, ndikofunika kwambiri kusankha mafuta omwe ali ndi khalidwe lokhazikika komanso kutentha kwabwino malinga ndi ntchito ya mankhwala, monga ngati kusindikiza ndi kupopera mankhwala kumafunika, kuti apange bwino komanso kusintha khalidwe la mankhwala.
