Lisebelisoa ke li-additives tsa bohlokoa ts'ebetsong ea PVC.Bakeng sa mafura, mesebetsi e atisang ho boleloa indastering e ka akaretsoa ka lintlha tse peli.Ke: e ka fokotsa khohlano pakeng tsa likaroloana le li-macromolecules ho PVC e qhibiliha pele e qhibiliha;Fokotsa likhohlano lipakeng tsa PVC e qhibilihang le bokaholimo ba mochini oa polasetiki.Sehloohong sa kajeno, moetsi oa Sainuoboka ba polyethylenee tla u isa ho hlahlobisisa lubrication ea kahare le kantle ea mafura a PVC ho latela pono ea tekheniki!

1. Ho tlotsa ka hare
Mafura a ka hare a mafura, ho ea ka PVC, a ka nkoa e le mofuta o tšoanang oa lintho tse kang li-plasticizers, ho bapala karolo ea polasetiki kapa ea ho nolofatsa.Phapang ke hore mafura a na le polarity e tlaase le liketane tse telele tsa carbon, tse fokotsang haholo ho lumellana pakeng tsa lubricant le polyvinyl chloride ha li bapisoa le li-plasticizers.Ka lebaka la tšebelisano e tlase (le ho lumellana ho itseng) pakeng tsa lubricant le polyvinyl chloride, ke limolek'hule tse nyane feela tsa lubricant tse ka kenang lipakeng tsa liketane tsa limolek'hule tsa polymer joalo ka li-plasticizers, tsa fokolisa ho hohelana pakeng tsa liketane tsa limolek'hule, le ho etsa hore polymer e holofale. le tšekamelo e eketsehileng ea ho thella le ho potoloha le e mong le tse ling tse, ha a ntse a sa ka tsela e feteletseng ho fokotsa mocheso phetoho khalase ea polymer.
2. Ho tlotsa ka ntle
Ho tlotsa ka ntle ho bolela mokhoa oa ho lubrication oa interface.Lisebelisoakhomarela bokaholimo ba resin e entsoeng ka ho qhibilihisoa kapa ka holim'a mochini oa ho lokisa le liforomo ho etsa lera la lubricant molecular.Ka lebaka la boteng ba likarolo tsa limolek'hule tsa lubricant, ho thehoa sebopeho sa lubrication, se fokotsang likhohlano lipakeng tsa resin le mochini o sebetsang.Viscosity ea filimi ea lubrication interface le ts'ebetso ea eona ea lubrication e itšetlehile ka ntlha ea ho qhibiliha le mocheso oa ho sebetsa oa lubricant.Ka kakaretso, litlolo tse nang le liketane tse telele tsa khabone ea molek'hule li na le litlamorao tse betere tsa ho lubrication ka lebaka la bokhoni ba tsona ba ho boloka libaka tse peli tsa likhohlano li le hole.

3. Ho etsahala'ng haeba setlolo sa PVC se sa sebelisoe hantle?
Poleloana 'tekanyo e nyane, phello e ntle' e hlalosa mafura a PVC.Karolo ea lubricant ea PVC ts'ebetsong ea PVC ha e ka tlase ho ea li-stabilizers.Tšebeliso ea eona ka kakaretso e latela melao-motheo e thata, e kang ho leka-lekana ka hare le ka ntle ho thella, tekanyo e itekanetseng, joalo-joalo Haeba ho se na khatello e lekaneng ea lisebelisoa tsa PVC 'me li kheloha melao-motheo e lokelang ho lateloa ha e sebelisoa, phello e tla ba efe haeba lisebelisoa tsa PVC ha li sebelisoe hantle?
(1) Ho se leka-lekane ho tlotsa ka hare le ka ntle
Ho thella ho feteletseng ka ntle, le hoja lebelo la extrusion le potlakile, thepa e atisa ho hōla le polasetiki ha e ntle;Ho thella ho feteletseng ka hare, molumo o moholo oa extrusion, le polasetiki e fokolang ea thepa.Tšebeliso e mpe ea pele e ka baka torque e feteletseng ea extrusion.Lubrication e sa lekaneng sethaleng sa morao-rao e ka lebisa ho lubrication e sa lekaneng karolong ea homogenization, karolo ea compression, le karolo ea lefu la screw, e bakang ho kuta ho matla ha thepa le ho ama boleng ba bokaholimo le ts'ebetso ea ka hare ea sehlahisoa se extruded.Maemong a matla, e ka boela ea baka ho bola.

(2) Tekanyo e feteletseng ea mafura a sebelisitsoeng
Litlolo ha li hlile ha li be betere ha li sebelisoa ka bongata.Ka lebaka la ho se lumellane pakeng tsa lubricant le PVC resin, tlatsetso e feteletseng ea mafura e ka ba le litlamorao tse mpe tsamaisong ea motsoako oa PVC.Tekanyo ea ka hare le ea ka ntle ea lubrication e boletsoeng e ka har'a moeli o itseng, kaha tsamaiso ea motsoako oa lubricant le polyvinyl chloride e na le liphello tse mpe.Tlhahisong ea 'nete, mathata a mangata a ts'ebetso le litaba tse amanang le botsitso ba mocheso, hammoho le liphoso tse ngata lihlahisoa, li ka bakoa ke tšebeliso e feteletseng ea mafura.
