Polyethylene serandi mtundu wa zinthu mankhwala, amene mtundu wa polyethylene sera ndi woyera yaing'ono mikanda / flakes, amene apangidwa ndi ethylene polima mphira processing wothandizila.Zili ndi makhalidwe osungunuka kwambiri, kuuma kwakukulu, gloss yapamwamba ndi mtundu wa chipale chofewa.Ikhoza kusungunuka pa 104-130 ℃ kapena kusungunula mu zosungunulira ndi utomoni pa kutentha kwakukulu, koma idzapitirirabe ikazizira.Kutentha kwake kwa mpweya kumakhudzana ndi kuzizira: tinthu tating'onoting'ono (5-10um) timapeza ndikuzizira pang'onopang'ono, ndipo tinthu tating'onoting'ono (1.5-3um) timatenthedwa ndi kuzizira kofulumira, popanga filimu yopaka ufa, pomwe filimuyo imapanga. ozizira,pa wax precipitates kuchokera ❖ kuyanika njira kupanga particles zabwino, amene tiyandama pamwamba pa filimuyo ndipo akhoza kuchita mbali ya kapangidwe, kutha, kusalala ndi zikande kukana.Mitundu yosiyanasiyana imatha kupezeka posankha bwino sera yaying'ono ya ufa ndi makina okutira.

1. Mphamvu ya sera ya polyethylene:
(1) Kusakaniza ndi kutha: pamene filimu yophimba itakhazikika, sera ya polyethylene imachokera ku zokutira ndikupita pamwamba pa filimu yophimba kuti ipange chitsanzo ndi kutha;Mu zokutira ufa, sera zosiyanasiyana zimachepetsa gloss mosiyana.Sera imatha kusankhidwa malinga ndi zofunikira za gloss.Kuphatikiza kwa sera ya polyethylene ndi 1%, 60, ndipo gloss imachepetsedwa ndi 5-15.
(2) kukaniza kukanika, kuvala kukana, kupukuta kukana ndi chosema kukana: polyethylene sera ndi mabatani yaying'ono alipo ❖ kuyanika pamwamba mu mawonekedwe a particles omwazikana.Chepetsani kugunda kwa coefficient of coefficient, kotero kuti chinthucho chikagundana ndi pamwamba, kutsetsereka kumakhala kokulirapo kuposa kukanda, kuchepetsa chizolowezi chopukuta chifukwa cha kugundana, ndikusunga kulimba kwa gloss.Kuphatikizika kwa 0.5-1% kumatha kuchepetsa kugunda kwamphamvu kwa kanema kuchokera pa 0,35 mpaka 0,25.Zinthu zina zikakumana ndi zinthu zokutidwazo, nthawi zina zimasiya zikwangwani zakuda pafilimuyo.Kuonjezera sera ya polyethylene mufilimuyi kungachepetse chizolowezi ichi kapena kupanga zizindikiro zosavuta kuzipukuta.
3Kuphatikiza kwa 0.5-3% kumatha kukulitsa mphamvu ya utoto wa pigment ndi 10-30%,
(4) Zotsatira za zokolola za extrusion: sera ya polyethylene imachepetsa wononga torque, ndipo kuwonjezera 1% kungapangitse zokolola za extruder ndi 5-25%.
(5) Kusalala ndi kapangidwe: sera ya polyethylene imapatsa filimuyo mawonekedwe abwino kwambiri.
(6) Madzi: filimu ya waxy ili ndi hydrophobicity yabwino.
(7) Kunyowetsa gawo lapansi: sera ya polyethylene imapangidwa kuchokera mufilimuyo, yomwe imathandiza kutulutsa mpweya womwe umayikidwa pagawo la porous.

2. Mlingo ndi njira yowonjezera: mlingo waukulu wa sera ya polyethylene ndi 1-3%, yomwe nthawi zambiri imawonjezedwa pamaso pa extrusion;Itha kuwonjezeredwa isanayambe komanso itatha kutulutsa, ndipo zotsatira zabwino kwambiri zitha kutheka ngati kuchuluka kwa positi sikuchepera 1%.
3. Zosiyanasiyana
(1) Low maselo kulemera polyethylene homopolymer sera ali ndi kutha bwino zotsatira ndi mabuku katundu;
(2) Sera yosinthidwa ya acyl imawonjezera kusagwirizana ndi chisokonezo m'zigawo zokutira.Kutentha-kusungunuka, kukhuthala kwa mamasukidwe ndi kugwedezeka kwapamwamba kwa dongosolo kumachepa kwambiri ndipo tsinde la sera limasamukira kumtunda.Chotsatira chake, filimu yophimba wandiweyani imapangidwa pamwamba pa zokutira pambuyo pochiritsa, zomwe zimapangitsa kuti gloss iwonongeke.Itha kugwiritsidwa ntchito kupatula zokutira ufa wa epoxy resin.
(3) Polyoxyethylene yosinthidwa sera ya polyethylene imakhala yabwino kukana kukangana, kukana kukanda kwambiri, kusalala komanso kapangidwe kake.Sera ya ufa imakhala ndi sera ya Teflon.Chifukwa sichingasungunuke, chimawunikira pamwamba ndi tinthu tating'onoting'ono, kukhala mzere woyamba wodzitchinjiriza motsutsana ndi kuvala ndikuwonjezera nthawi yosavala kuchokera pamwamba.Pamene filimuyo akazizira, polyethylene sera precipitates ku ❖ kuyanika madzi kupanga particles zabwino, amene tiyandama pa filimu pamwamba, kusewera ndi kusalala ndi zikande kukana, kukhala mzere wachiwiri wa chitetezo kuvala.Kuphatikiza kwabwino kwa Teflon ndi polyethylene, Onsewa ali ndi ubwino wa mitundu iwiri ya ufa wa sera, ndipo kuumitsa kwake ndikwabwino kwambiri.
