Mafuta ndi zowonjezera zofunika pakukonza PVC.Kwa mafuta opangira mafuta, ntchito zomwe zimatchulidwa kawirikawiri mumakampani zitha kufotokozedwa mwachidule m'magawo awiri.Iwo ndi: akhoza kuchepetsa kukangana pakati pa particles ndi macromolecules mu PVC Sungunulani pamaso kusungunuka;Chepetsani kukangana pakati pa PVC kusungunuka ndi pulasitiki makina kukhudzana pamwamba.M'nkhani ya lero, wopanga Sainuophula la polyethylenezidzakutengerani kuti mufufuze zodzola zamkati ndi zakunja zamafuta a PVC kuchokera paukadaulo!

1. Kupaka mafuta mkati
Mafuta amkati amafuta, malinga ndi PVC, amatha kuonedwa ngati chinthu chofanana ndi mapulasitiki, kusewera pulasitiki kapena kufewetsa.Kusiyana kwake ndikuti mafuta ali ndi polarity yotsika komanso unyolo wautali wa kaboni, womwe umachepetsa kwambiri kuyanjana pakati pamafuta ndi polyvinyl chloride poyerekeza ndi mapulasitiki.Chifukwa cha kuyanjana kochepa (ndi kuyanjana kwina) pakati pa mafuta ndi polyvinyl chloride, mamolekyu ochepa okha amafuta amatha kulowa pakati pa maunyolo a polima monga mapulasitiki, kufooketsa kukopana pakati pa unyolo wa maselo, ndikupangitsa kuti polima apunduke, unyolo wa mamolekyulu ndi sachedwa kutsetsereka ndi kasinthasintha wina ndi mzake, osati mopitirira muyeso kuchepetsa galasi kusintha kutentha kwa polima.
2. Mafuta akunja
Kondomu kunja amatanthauza mawonekedwe kondomu limagwirira.Mafutakumamatira pamwamba pa utomoni wosungunuka kapena pamwamba pa makina opangira makina ndi nkhungu kupanga mafuta osanjikiza maselo.Chifukwa cha kukhalapo kwa zigawo zopangira mafuta, mawonekedwe opaka mafuta amapangidwa, omwe amachepetsa kukangana pakati pa utomoni ndi makina opangira.Kukhuthala kwa filimu yowonetsera kondomu ndi kutsekemera kwake kumadalira malo osungunuka ndi kutentha kwa kutentha kwa mafuta.Nthawi zambiri, mafuta okhala ndi unyolo wautali wa ma molekyulu a kaboni amakhala ndi zokometsera bwino chifukwa amatha kusungitsa mikangano iwiri.

3. Chimachitika ndi chiyani ngati mafuta a PVC sagwiritsidwa ntchito bwino?
Mawu akuti 'kalingo kakang'ono, zotsatira zabwino' amafotokoza mafuta a PVC.Udindo wamafuta a PVC pakukonza PVC siwocheperako kuposa okhazikika.Kugwiritsiridwa ntchito kwake kumatsatira mfundo zokhwima, monga mkati ndi kunja kutsetsereka bwino, mlingo wapakatikati, ndi zina zotero. osagwiritsidwa ntchito bwino?
(1) Kupaka mafuta mkati ndi kunja kosakwanira
Kutsetsereka kwakunja kwakunja, ngakhale kuthamanga kwa extrusion kumakhala kofulumira, zinthuzo zimakonda kukula ndipo pulasitiki si yabwino;Kutsetsereka kwambiri mkati, voliyumu yayikulu yotulutsa, komanso pulasitiki yoyipa.Mafuta oyambira osakwanira amatha kuyambitsa torque yochulukirapo.Osakwanira kondomu mu siteji kenako kungachititse kuti kokwanira kondomu mu gawo homogenization, psinjika chigawo, ndi kufa gawo la wononga, chifukwa kwambiri akumeta ubweya wa zinthu ndi zimakhudza pamwamba khalidwe ndi ntchito mkati mwa mankhwala extruded.Pazovuta kwambiri, zimathanso kuyambitsa kuwonongeka.

(2) Kuchuluka kwa mafuta odzola omwe amagwiritsidwa ntchito
Mafuta odzola sakhala bwino ndi kuchuluka kwakukulu.Chifukwa cha kusagwirizana pakati pa mafuta ndi utomoni wa PVC, kuwonjezera kwambiri kwa mafuta kungakhale ndi zotsatira zoipa pa dongosolo lophatikizana la PVC.Kuchuluka kwa mkati ndi kunja kwa mafuta omwe akutchulidwa kuli mkati mwa malire ena, monga mafuta osakaniza ndi polyvinyl chloride blend system ali ndi zotsatirapo zoipa.Pakupanga kwenikweni, zovuta zambiri zamakasitomala ndi zovuta zokhudzana ndi kukhazikika kwamafuta, komanso zolakwika zambiri pazogulitsa, zitha kuchitika chifukwa chogwiritsa ntchito kwambiri mafuta.
