Polyethylene sera (Pe sera), yomwe imadziwikanso kuti sera ya polima, imatchedwa pe sera mwachidule.Chifukwa cha kukana kwambiri kuzizira, kukana kutentha, kukana kwa mankhwala ndi kukana kuvala, wakhala akugwiritsidwa ntchito kwambiri.Pakupanga kwabwinobwino, gawo ili la sera litha kuwonjezedwa mwachindunji ku polyolefin pokonza ngati chowonjezera, chomwe chimatha kuwonjezera kuwala ndi kusinthika kwazinthu.Monga mafuta, imakhala ndi mankhwala okhazikika komanso magetsi abwino.
Sera ya polyethylene imagwirizana bwino ndi polyethylene, polypropylene, polyvinyl acetate, mphira wa ethylene propylene ndi mphira wa butyl.Ikhoza kusintha fluidity wa polyethylene, polypropylene ndi ABS ndi depoulding katundu wa polymethylmethacrylate ndi polycarbonate.
Kwa PVC, pa wax ali ndi mafuta amphamvu mkati kuposa mafuta ena akunja.

Kodi phula la polyethylene ndi chiyani?
1. Sera ya PE ya PVC stabilizer
(1) Sera yoyera ya polyethylene imatsimikizira kukhazikika kwa stabilizer.
(2) Mafuta abwino kwambiri, kuchedwetsa pulasitiki ndikuchepetsa torque.
(3) Pambuyo pake, imakhala ndi kukhazikika kwabwino kwa kutentha ndipo ilibe oligomer, parafini, ndi zina zotero.
(4) Ikhoza kupititsa patsogolo kuwala kwa zinthu.
2. Sera ya PE ya filler masterbatch
(1) Chogulitsacho chimakhala ndi mafuta abwino pokonza kudzaza kwa masterbatch, komwe kumatha kuthetsa vuto la mvula pakudzaza zinthu za masterbatch.
(2) Ikhoza kuchepetsa utsi wopangidwa m'malo opangira zinthu, kuchepetsa kugwiritsira ntchito zinthu, makamaka kuonjezera zotulukapo, kuchepetsa mphamvu ya makokedwe ndi mutu wa mapasa-screw extruder granulator, ndi kuchepetsa injini yaikulu yamakono.
(3) Ikagwiritsidwa ntchito muzinthu zapulasitiki, kufalikira kwa zinthuzo kumakhala kofanana, ndipo mawonekedwe azinthuwo amawongoleredwa bwino, zomwe zimatha kusintha kwambiri kutha kwa zinthuzo komanso kulimba kwazinthuzo.

3. Sera ya PE ya mtundu wa masterbatch
(1) Kuwonjezera polyethylene sera kwa mtundu masterbatch timapitiriza wetting ndi malowedwe mpweya wakuda aggregates, amachepetsa awo tinthu kukula mwa kukameta ubweya mphamvu, ndi bwino ngakhale pakati pa dongosolo ndi mpweya wakuda, amene amathandiza kubalalitsidwa;
(2) Ikhoza kupititsa patsogolo ntchito ndi kutulutsa.The mamasukidwe akayendedwe wa sera polyethylene ndi otsika kwambiri kuposa chonyamulira utomoni chifukwa otsika maselo kulemera, amene akhoza kwambiri kuchepetsa mamasukidwe akayendedwe a mbuye mtanda kusungunuka.
4. Sera ya PE yomatira yosungunuka yotentha
Sera ya polyethylene imakhala yokhazikika komanso yokhazikika yotentha ikagwiritsidwa ntchito pazomatira zotentha zosungunuka.Chotsatira chake, sichidzawomba kutentha kwakukulu ndipo sichidzakhudza maonekedwe ndi katundu wa zomatira zotentha zosungunuka.Zomatira zotentha zosungunuka zomwe zimapangidwa powonjezera sera ya polyethylene zimakhala ndi kuzizira kwabwino, kukana kutentha, kukana kwa asidi alkali komanso kukhazikika kwamafuta, anti sliding, kukhazikika bwino, mphamvu yomangirira kwambiri komanso kukana kutentha kwambiri.

(1) Kugwirizana kwakukulu (kusintha kwa polarity).
(2) Maonekedwe a pamwamba (kunyezimira, kusalala, kusagwa mvula).
(3) Kukhazikika kwabwino kwamafuta (palibe chikoka pamtundu wa utomoni, wopanda chikasu).
(4) Polima wolemera kwambiri wa mamolekyulu (otsika osasunthika, osasuntha).
(5) Kuwongolera konyowetsa komanso kumamatira.
(6) Wonjezerani mphamvu.
(7) Kupititsa patsogolo katundu pambuyo pochiritsa.
(8) Sinthani maola otsegulira ndi nthawi yochiritsa.
