Polyethylene serandi ufa woyera wokhala ndi malo ochepetsetsa pafupifupi 100-117 ℃.Chifukwa cha kulemera kwake kwakukulu kwa maselo, malo osungunuka kwambiri komanso kusasunthika kochepa, kumawonetsanso zowoneka bwino zamafuta pa kutentha kwakukulu ndi kumeta ubweya.Ndi yoyenera kwa PVC yolimba ya single and twin-screw extrusion, yokhala ndi kuchuluka kwa 0.1-0.5phr.

Pakupanga mbiri ya chitoliro cha PVC, padzakhala zochitika zosawoneka bwino komanso zowala bwino.Parafini, monga mafuta a PVC, imakhala ndi malo ochepetsetsa komanso kubalalitsidwa kosakwanira.Chifukwa cha kutentha kwambiri popanga, parafini imasungunuka ndikusinthidwa kukhala mpweya.Ndizovuta kuti parafini igwire ntchito pakugwiritsa ntchito mapaipi a PVC.Kubalalika sikuli bwino, ndipo mbiri ya chitoliro cha PVC idzadetsedwa kuchokera pamwamba.
Mbiri ya PVC chitoliro opangidwa ndi polyethylene sera (PE sera) sadzakhala ndi mavuto amenewa, chifukwa kufewetsa mfundo ya polyethylene sera nkhuni thupi ndi mkulu, ndipo pansi pa kutentha kwambiri, polyethylene sera (PE sera) adzakhala madzi, ndi kukhuthala mkulu ndi Kusabalalika koyipa kwa sera ya polyethylene (phula la PE), koma kuwala kwake ndikwabwino kwambiri.Ngati kukhuthala kwa phula la polyethylene (phula la PE) kuli kochepa, kubalalitsidwa ndikwabwino kwambiri ndipo kuwala kuli bwino.
Qingdao Sainuophula la polyethyleneyakhazikika kwambiri kugawa kwa kaboni, kugawa kwamphamvu kwa maselo, kuchepa kwamafuta ochepa komanso kuchita bwino koyambirira, pakati komanso mochedwa.Low mamasukidwe akayendedwe, mkulu kufewetsa mfundo, lalikulu molekyulu kulemera, wabwino matenthedwe bata, bwino kwambiri mafuta kunja ndi kolimba mkati mafuta.Zosavuta kumwazikana, zomwe zimatha kusintha kwambiri gloss ya zinthu;Kugwirizana kwabwino, kogwirizana ndi zinthu zambiri komanso anti-precipitation;Kuchita bwino kwa depoulding, nthawi yayitali yopitilira kupanga ndi zabwino zina, zokhala ndi mawonekedwe abwino kwambiri.Tidzasankha sera yoyenera ya polyethylene malinga ndi zosowa zosiyanasiyana za makasitomala.

Sera ya polyethylene imakhala ndi malo amphamvu kwambiri a polar komanso unyolo wautali wa carbon wosakhala wa polar.Mu kapangidwe ka sera ya polyethylene, gawo logwirizana ndi pulasitiki mu polarity limagwira ntchito yopaka mafuta mkati, ndipo gawo losagwirizana ndi pulasitiki mu polarity limagwira ntchito yopaka kunja ndikuchotsa.
Ntchito yofunika kwambiri ya sera ya polyethylene ili pakukonza PVC.Poyerekeza ndi mafuta opangira mafuta a asidi, sera ya polyethylene ilibe vuto lililonse pakusungunuka kwamphamvu ndi Vicat kufewetsa malo, ndipo imapatsa anti adhesion ndi kuwongolera koyenda.Mu njira zapadera zopangira, sera ya PE ingagwiritsidwe ntchito poletsa kusungunuka.Ngakhale kuchuluka kwake kuli kwakukulu, kumatha kukhala kogwirizana ndi zigawo zina.
Sera ya polyethylene ndiye mafuta okhawo odziwika bwino a pulasitiki omwe amatha kudzoza mkati ndi kunja (kuchepetsa mphamvu), kukhalabe kuwonekera kwambiri komanso kukhala ndi zotsatira zochepa pa gelation.Kuphatikiza apo, kusakhazikika kochepa kwa sera ya PE ndikofunikira kwambiri pakupanga ma calendering ndi vacuum degassing,.
Monga mafuta amkati, sera ya polyethylene imagwirizana bwino ndi ma polima.Imathandizira kuchepetsa mgwirizano pakati pa mamolekyu a polima mu polima, kuti apititse patsogolo kutentha kwamkati kwamkati ndikusungunula kusungunuka kwa pulasitiki.
Ntchito ya Pe phula ngati lubricant kunja makamaka kusintha mikangano pakati polima Sungunulani ndi otentha zitsulo pamwamba pa processing zida.Zili ndi kusagwirizana bwino ndi polima ndipo ndizosavuta kusuntha kuchoka kusungunuka kupita kunja, kotero zimatha kupanga mafuta ochepetsetsa omwe ali pakati pa pulasitiki yosungunuka ndi zitsulo.
Malingaliro a kampani Qingdao Sainuo Chemical Co.,Ltd.Ndife opanga sera PE, PP sera, OPE sera, EVA sera, PEMA, EBS, Zinc / Calcium Stearate….Zogulitsa zathu zadutsa REACH, ROHS, PAHS, FDA kuyesa.
