M'lingaliro laling'ono,phula la polyethylenendi otsika wachibale maselo kulemera homopolymer polyethylene;Mwanjira yotakata, sera ya polyethylene imaphatikizansopo sera yosinthidwa ya polyethylene ndi copolymerized.pa wax.Kawirikawiri, ngati polyethylene polima sangathe kupereka mphamvu inayake ndi kulimba ngati utomoni, ndipo sangathe kukonzedwa ngati chinthu chimodzi mu mankhwala kuti pamapeto pake ali ndi ntchito inayake, tikhoza m'gulu sera polyethylene.

Sera ya polyethylene imagwiritsidwa ntchito kwambiri mu mapulasitiki ngati dispersant kwa inki, monga lubricant kwa PVC blends, monga otaya zosintha ndi compatibilizer mu PE ndi PP modifiers.
Dzina lonse la PVC ndi PVC.Kutentha kwake kothamanga kwa viscous kuli pafupi kwambiri ndi kutentha kwachiwonongeko, choncho n'zosavuta kuti muwononge mitundu yosiyanasiyana ya zowonongeka panthawi yokonza, zomwe zimapangitsa kuti musamagwiritse ntchito.
Choncho, kutentha stabilizers ndi lubricant ziyenera kuwonjezeredwa pakupanga PVC akasakaniza, kale kupititsa patsogolo bata awo matenthedwe, yotsirizira kuchepetsa mikangano pakati PVC unyolo maselo, ndi filimu kumasulidwa mphamvu pakati PVC Sungunulani ndi zitsulo, kuwongolera yabwino processing PVC. kuzinthu zosiyanasiyana.Sera ya polyethylene ndi sera ya polyethylene oxidized ndi mafuta omwe amapezeka mu PVC.
Pakukonza PVC, palibe kusungunuka koyera, tinthu tating'ono ting'onoting'ono (100 μ Pafupifupi m, tokhala ndi tinthu tating'onoting'ono tomwe timayambira ndi tinthu tating'onoting'ono) tomwe timatenthetsa ndikumeta ubweya wamakina, kugawanika kukhala mipira yaying'ono (1 μM kapena kotero), ndondomeko ya globules kugawanika kachiwiri mu tinatake tozungulira (100 nm).

Njirayi imatchedwa gel kapena pulasitiki.Kuti mukwaniritse bwino makina, katundu pamwamba ndi processability, mlingo wa gel osakaniza ndi pakati 70% ndi 85%.
Kusankhidwa koyenera kwa sera ya polyethylene kumatha kuchedwetsa kapena kufulumizitsa gel osakaniza.Pambuyo kusungunuka, homopolymer polyethylene sera alipo pakati particles chachikulu kapena tinatake tozungulira, kuchepetsa mikangano pakati particles chachikulu kapena tinatake tozungulira, potero kuchepetsa frictional kutentha m'badwo wa Sungunulani, kuchedwa ndi plasticization wa PVC, ndi kuwongolera matenthedwe bata la PVC.
Sera yokhala ndi okosijeni ya polyethylene imakhala ndi kuyanjana kwina ndi PVC, yomwe imatha kuphatikizira pamwamba pa tinthu tating'onoting'ono, kuonjezera kukhuthala kwa ma viscosity, ndikulimbikitsa pang'ono gel osakaniza;
Ntchito yake ina yaikulu ndi kupanga filimu pamwamba pa PVC kusungunuka ndi zitsulo, kuchepetsa mikangano pakati pa kusungunula ndi kukonza zipangizo.Ndiwotulutsa wabwino pokonza PVC, makamaka m'mafilimu owonekera a PVC (organic tini stabilizer).Kuonjezera kuchuluka koyenera kwa sera ya polyethylene yokhala ndi okosijeni sikumangotulutsa bwino, komanso sikuchepetsa kuwonekera.
Panopa, kuwonjezera kupanga polyethylene sera ndi oxidized polyethylene sera.Sera ya parafini, sera ya Fischer Tropsch, ndi phula lopangidwa ndi mankhwala amagwiritsidwanso ntchito kwambiri mu PVC, ndipo amayeneranso kufananizidwa mosinthika malinga ndi momwe angagwiritsire ntchito ma terminal.

Mwachitsanzo, sera ya parafini yotsika kwambiri imatha kuthandizira kudzoza koyambirira, sing'anga yosungunuka sera ya polyethylene ndi Fischer Tropsch sera imathandizira pakupaka mafuta apakatikati, ndipo sera yosungunuka kwambiri ya oxidized polyethylene imatha kupangitsa kuti mafuta azikhala mochedwa.
Mafuta ena osakanizidwa ndi kutentha pang'ono, monga parafini ndi mafuta acid esters, amakonda kuyika pamutu wa zinthu zotulutsa ndi zoziziritsa kuziziritsa zamafilimu opangira kalendala.Zinthu izi zimatha kukhala ndi zotsatira zoyipa pazomwe zili pamwamba pa zinthu zomaliza, komanso malo ogwirira ntchito komanso kupanga ogwira ntchito pamalowo.Kuphatikiza apo, kuphatikiza kwamafuta amodzi mu PVC ndikokwera kwambiri.Ngati phukusi lamafuta ophatikizika likugwiritsidwa ntchito, zigawo zosiyanasiyana sizingathe kulekerera ndikuchitana, zomwe zingayambitse kupanikizika.
Choncho, kusankha mafuta odzola okhala ndi khalidwe lokhazikika komanso kukana kutentha kwabwino kutengera ntchito zomwe zimagwiritsidwa ntchito monga kusindikiza ndi kupopera mankhwala ndizofunikira kwambiri pakupanga bwino komanso kukonza khalidwe la mankhwala.
Kuti mudziwe zambiri, chonde tiuzeni!
