Polyethylene seraali ndi ntchito zambiri ndipo amagwiritsidwa ntchito kwambiri.Sera ya polyethylene imagwira ntchito yoletsa kukhazikika mu utoto wapansi.Mapangidwe a sera a polyethylene amapangidwa ndi polymerization yaulere ya ethylene ndi ma monomers ena opanikizika kwambiri, ndipo amathanso kupangidwa kudzera pakuwonongeka.Itha kukhalanso okosijeni ndikuyambitsidwa ndi magulu osiyanasiyana a polar monga magulu a carboxyl panthawi yopanga.Kulemera kwa mamolekyu nthawi zambiri kumakhala pafupifupi 2500, ndipo mamolekyu ena a sera amakhala ndi magulu a polar okhala ndi zigawo zozungulira.

Pambuyo powonjezera gawo la zosungunulira, sera ya ufa imatenthedwa ndi kusungunuka, kusungidwa pa madigiri 60 Celsius, ndi kumwazikana mu phala.Mukawonjezeredwa ku utoto wapansi, umakhala ngati thixotropic ndi anti settling agent.
Pe phulailinso ndi zinthu zina zomangika za waxy zomwe zimakhala ndi mphamvu yokwerera.Ndalama zina zikawonjezeredwa, zimakhala ndi zotsatira za matting.Ngati ndalamazo zachepetsedwa moyenera, zimakhala ndi anti-setting effect ndi anti rolling effect.Akagwiritsidwa ntchito mu pearlescent kapena utoto wazitsulo, amatha kupeza filimu yokutira mpaka.

Sera ya polyethylene ndi yofanana ndi zinthu zina zingapo zoletsa kukhazikika.Mphamvu yoletsa kukhazikika ya sera ya polyethylene ndi yabwino, koma kapangidwe kake kamakhalanso kokwera kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kwambiri zokutira zapamwamba.Chitukuko chapamwamba cha utoto wapansi chikugwirizana ndi chikhalidwe ichi, ndipo ndi chitukuko chafupipafupi, mitundu yosiyanasiyana ya mankhwala omwe ali ndi ntchito yabwino idzavomerezedwa kwambiri.
TheSainuo pe sera SN9038Aamaphatikiza kunyowetsa, kubalalitsidwa, ndi mafuta.Madziwo ndi owonekera komanso opanda zonyansa, zomwe zingapangitse kuwala kwa mankhwalawo.Chojambuliracho chimakhala ndi kuphimba bwino, kulemera kochepa kwa maselo, anti precipitation, ndipo kumatha kupititsa patsogolo kuyendetsa bwino kwa masterbatch.Amagwiritsidwa ntchito kwambiri pamakampani a PVC, calcium zinc, lead salt stabilizer, kudzaza ma masterbatches, ma masterbatches owoneka bwino, ma masterbatches otsika, ma masterbatches osavuta, ndi mafakitale ena.

Malinga ndi machitidwe osiyanasiyana ogwiritsira ntchito, tikulimbikitsidwa kuwonjezera mankhwala a PVC ndi gawo la 0.5-1%, okhazikika a 5-20%, odzaza 4-6%, ndi masterbatch amtundu wa 3-5%;Nthawi zambiri, imatha kuwonjezeredwa mwachindunji ndikubalalitsidwa kudzera kusanganikirana kothamanga kwambiri komanso kusonkhezera, ndi kutentha koyenera ndi nthawi yoyendetsedwa kuti mukwaniritse zotsatira zabwino kwambiri za kubalalitsidwa.
