Kuwonekera kwapamwamba kumathandizira kuzindikiritsa katundu;kutalika kwautali wautali kumathandizira kutambasula kusanachitike ndikupulumutsa kugwiritsa ntchito zinthu;ntchito yabwino ya puncture ndi mphamvu yodutsa misozi imalola filimuyo kukumana ndi ngodya zakuthwa kapena Mphepete mwake siimathyoka;zokolola zambiri zimapangitsa kuti katundu wopakidwa azikhala wothina.
Kanema wopangidwa ndi njira yoponyera ali ndi kuwonekera kwakukulu.Ndi kuchuluka kwa maatomu a C a comonomer ya zinthuzo, kutalika kwa unyolo wanthambi kumawonjezeka, crystallinity imachepa, ndipo "kupiringa kapena kinking" zotsatira za copolymer zomwe zimachokera kumawonjezeka, kotero kuti elongation ikuwonjezeka, ndi mphamvu ya puncture. mphamvu ya misozi imawonjezekanso.Ndipo MPE ndi polima kwambiri stereoregular ndi yopapatiza maselo kulemera kugawa, amene angathe kulamulira molondola katundu thupi la polima, kotero ntchito yake ndi bwino;ndipo chifukwa MPE ali yopapatiza maselo kulemera kugawa ndi yopapatiza processing osiyanasiyana, n'zovuta kulamulira zinthu processing.Onjezani 5% LDPE kuti muchepetse kukhuthala kosungunuka ndikuwonjezera kusalala kwa filimuyo.
Mtengo wa MPE ndiwokweranso.Pofuna kuchepetsa ndalama, MPE nthawi zambiri imagwiritsidwa ntchito limodzi ndi C4-LLDPE, koma si C4-LLDPE yonse yomwe ingagwirizane nayo, kotero payenera kukhala kusankha.Makanema otambasulira ogwiritsa ntchito makina nthawi zambiri amagwiritsa ntchito zida za C6 ndi C8, zomwe ndi zosavuta kuzikonza ndipo zimatha kukwaniritsa zofunikira zosiyanasiyana zamapaketi.Pakuyika pamanja, zida za C4 zimagwiritsidwa ntchito kwambiri chifukwa chakuchepa kotambasula.
Kuchuluka kwa zinthu kumakhudzanso momwe filimuyi ikuyendera.Pamene kachulukidwe kachulukidwe kake, kuchuluka kwa kupendekera kumawonjezeka, kutsetsereka kumakhala bwino, kutalika kwautali kumawonjezeka, ndipo mphamvu zokolola zimawonjezeka, koma mphamvu yong'ambika yodutsa, mphamvu ya puncture ndi transmittance kuwala zonse zimachepa.Chifukwa chake, magwiridwe antchito azinthu zonse nthawi zambiri amakhala osamata Onjezani kuchuluka koyenera kwa polyethylene yapakatikati (LMDPE) mpaka wosanjikiza.Kuonjezera LMDPE kungathenso kuchepetsa kugundana kwa wosanjikiza wosamata ndikupewa kumamatira kwa phale lopakidwa pallet.
Mphamvu ya kuzirala mpukutu kutentha.Pamene kutentha kwa mpukutu wozizira kumawonjezeka, mphamvu zokolola zimawonjezeka, koma katundu wina amachepetsa.Choncho, kutentha kwa mpukutu wozizira I nthawi zambiri kumayendetsedwa pa 20 ° C mpaka 30 ° C.Kuthamanga kwa mzere woponyera kumakhudza flatness ndi mapindikidwe zolimba za filimuyo.Ngati PIB kapena masterbatch ake amagwiritsidwa ntchito ngati wosanjikiza womata, zimakhudzanso kusamuka kwa PIB ndikuchepetsa kukhuthala komaliza kwa filimuyo.Kuchulukana nthawi zambiri sikudutsa 10kg.Kupsyinjika kwakukulu kudzakhalabe mu mpukutu wa filimuyo, zomwe zidzachepetse elongation ndi katundu wina ndikupangitsa kuti filimu iwonongeke mosavuta.Fomu yogwiritsira ntchito filimu yotambasula
Filimu yotambasula imakhala ndi ntchito zambiri, zomwe zimagwiritsidwa ntchito molumikizana ndi mapaleti, kuyika katundu wamwazikana mochulukira, m'malo mwa zotengera zazing'ono.Chifukwa amatha kuchepetsa mtengo wonyamula katundu wochuluka ndi kulongedza kwambiri kuposa 30%, amagwiritsidwa ntchito kwambiri pakupakira zinthu zosiyanasiyana monga zida, mchere, mankhwala, mankhwala, chakudya, makina, ndi zina;m'munda wa zosungiramo zosungiramo katundu, zimagwiritsidwanso ntchito kwambiri kunja.Mapallet amakanema amayikidwa kuti asungidwe ndi magawo atatu kuti asunge malo ndi ntchito.
