Chidule: Nkhaniyi ikufotokoza makamaka zifukwa zomwe zimapangitsa kuti filimu yophatikizana ikhale yolimba komanso mfundo zowongolera njira pambuyo pa kuchiritsa kwa PE.
Zipangizo za PE (polyethylene) zimagwiritsidwa ntchito kwambiri popanga ma CD osinthika, Pogwiritsa ntchito ukadaulo wopanda zosungunulira, padzakhala mavuto ena osiyana ndi njira zina zophatikizika, makamaka samalani kwambiri pakuwongolera njira.
- 1.Mavuto ofala a njira zophatikizira zopanda solvent za PE
1) Popanga matumba, matumbawo amatuluka pamwamba pake moterera kwambiri komanso movuta kusonkhanitsa.
2) Kuvuta kulemba ma code (Chithunzi 1)
3) Liwiro la zinthu zozungulira silingakhale lachangu kwambiri.
4) kutsegula koyipa (Chithunzi 2)

- 2.Zifukwa zazikulu
Mavuto omwe ali pamwambawa amawonekera m'njira zosiyanasiyana, ndipo zifukwa zake ndi zosiyana. Chifukwa chachikulu ndichakuti kapangidwe ka polyether mu guluu wopanda solvent lamination kamagwirizana ndi chinthu chotsetsereka mufilimuyi, zomwe zimapangitsa kuti kapangidwe ka chinthu chotsetsereka chomwe chalowetsedwa pamwamba pa filimu ya polyethylene chisamukire mkati kapena kunja, zomwe zimapangitsa kuti filimu yosakanikirana ikhale yolimba kwambiri ikakonzedwa. Izi zimachitika nthawi zambiri pamene PE ndi yopyapyala.
Nthawi zambiri, mavuto a PE si chifukwa cha chinthu chimodzi, koma nthawi zambiri amakhala okhudzana ndi zinthu zingapo, kuphatikizapo kutentha kozizira, Kulemera kwa Coating, kupsinjika kwa winding, kapangidwe ka PE ndi mphamvu zomatira zopanda zosungunulira.
- 3.Mfundo ndi njira zowongolera
Mavuto a PE omwe ali pamwambapa amayamba chifukwa cha kuchuluka kwa friction coefficient, komwe kumatha kusinthidwa ndikuwongoleredwa ndi njira zotsatirazi.
| NO | Zinthu zowongolera | Malo olamulira |
| 1 | Kutentha kwa kuphatikiza ndi kuchiritsa | Kutentha kwa compound ndi cleaving kuyenera kukhala koyenera, nthawi zambiri kumakhala pa 35-38℃. Kutentha kwa cleaving ndi cleaving kumakhala kovuta kwambiri pakuwonjezeka kwa friction coefficient, kutentha kukakwera, guluu wopanda solvent lamination umakumana ndi chinthu chotsetsereka mu filimuyi. Kutentha koyenera kungatsimikizire kuti friction coefficient ndi yoyenera ndipo sikukhudza mphamvu ya peel. |
| 2 | Kulimba kwa kugwedezeka | Kukanikiza kwa maginito kuyenera kukhala kochepa momwe zingathere ngati palibe makwinya ndi thovu pamwamba pa zinthu zophatikizika zitakonzedwa. |
| 3 | Kulemera kwa Kuphimba | Pansi pa mfundo yotsimikizira mphamvu ya peel, Kulemera kwa Coating kumawongoleredwa pang'ono kuposa mtengo wotsika. |
| 4 | Filimu ya polyethylene yopangira zinthu zopangira | Onjezani chinthu choterera kwambiri kapena onjezerani kuchuluka koyenera kwa chinthu chotsegulira chosapangidwa ndi organic, monga silika differential |
| 5 | Guluu woyenera | Sankhani mitundu yomatira yopanda zosungunulira makamaka yokhudzana ndi friction coefficient |
Kuphatikiza apo, kupanga kwenikweni kudzakumana ndi vuto laling'ono la kukangana nthawi zina, ndipo kudzachita zinthu zina mosiyana ndi zomwe zili pamwambapa malinga ndi momwe zinthu zilili.
