isicelo

Eyaziwa kakhulu nge-POLYVINYL CHLORIDE FILM, yenziwa ngeI-PVC resinnezinye izilungisi ngenqubo ye-calender noma inqubo yokubumba igalelo.Ubukhulu obujwayelekile bungu-0.08~ 0.2mm, bukhulu kuno-0.25mm obubizwa ngeshidi le-PVC.I-PVC resin yengeza i-plasticizer, i-stabilizer, i-lubricant kanye nokunye okusebenzayo okucutshungulwa kwe-AIDS, ifilimu ye-calendering.

Lolu hlobo lokulondolozwa kokushisa kwefilimu, ukudluliswa kokukhanya kuhle, kuthambile futhi kulula ukubumba, kufanelekile ku-greenhouse, i-greenhouse kanye nempahla encane yokumboza yangaphandle.

Ukungalungi yilezi: ingxenye yefilimu ephansi, izindleko eziphezulu;Ukumelana nesimo sezulu esibi, kunzima futhi ku-brittle ekushiseni okuphansi, kulula ukuthambisa nokukhululeka ekushiseni okuphezulu;Ngemva kwezulu izithasiselo, ifilimu surface vacuuming, ezithinta ukudluliswa ukukhanya;Ifilimu eyinsalela ayiwohloki futhi yokwelashwa kokusha.

Ifilimu ye-PVC ingahlukaniswa izigaba ezimbili, enye i-PVC Film, eyaziwa nangokuthi ifilimu ye-PVC ethambile (ifilimu ye-PVC eyenziwe ngepulasitiki), enye ayiyona ifilimu ye-PVC eyenziwe ngepulasitiki, eyaziwa nangokuthi ifilimu ye-PVC eqinile (Ifilimu ye-PVC Engafakwanga) Phakathi kwayo, I-akhawunti ye-PVC eqinile cishe i-2/3 yemakethe, nama-akhawunti e-PVC aguqukayo angu-1/3.

I-PVC ethambile ngokuvamile isetshenziswa phansi, ophahleni nangaphezulu kwesikhumba, kodwa ngenxa yokuthi i-PVC ethambile iqukethe isithambile (lokhu futhi umehluko phakathi kwe-PVC ethambile ne-PVC eqinile), kulula ukuba yi-brittle, akulula ukuyigcina, ngakho ukusetshenziswa kwayo kulinganiselwe I-PVC ayiqukethe i-ejenti ethambisayo, ngakho-ke ukuguquguquka, ukubumba okulula, okunganqamuki, okungangcoliswanga okungeyona ubuthi, isikhathi sokulondoloza side, ngakho-ke ukuthuthukiswa kanye nokusetshenziswa kwenani elikhulu lefilimu ye-PVC kuwumgogodla wefilimu ye-vacuum blister, esetshenziselwa zonke izinhlobo zephaneli yongqimba lwamaphaneli wokupakisha, owaziwa nangokuthi ifilimu yokuhlobisa Namathisela ifilimu, esetshenziswa ekwakheni umuthi wokupakisha wezinto zokwakha, nezinye izimboni eziningi Imboni yezinto zokwakha ibalwa ngengxenye enkulu, i-60%, ilandelwa yimboni yokupakisha, kukhona inani lezinye izinhlelo zokusebenza ezincane zemboni ngokusho kwefilimu eyenza ukuhlukaniswa kwezinto zokusetshenziswa: ifilimu ye-polyethylene, ifilimu ye-polypropylene, ifilimu ye-PVC nefilimu ye-polyester Ngokusho kwesigaba sokusetshenziswa kwefilimu: ifilimu yezolimo (lapha ngokusho kokusetshenziswa okuqondile kwefilimu yezolimo, ingakwazi ihlukaniswe ifilimu ye-mulching nefilimu ye-greenhouse);Ifilimu yokupakisha (ifilimu yokupakisha ngokwezinjongo zayo ezithile, futhi ingahlukaniswa ifilimu yokupakisha ukudla nazo zonke izinhlobo zemikhiqizo yezimboni enefilimu yokupakisha, njll.) futhi isetshenziswa endaweni ekhethekile ifilimu ephefumulayo ene-USES ekhethekile, ifilimu encibilikayo emanzini futhi ine ukusebenza kwefilimu elincanyana le-piezoelectric nokunye Ngokusho kwezindlela zokwenza ukuhlukaniswa kwefilimu: i-extrusion plasticizing Bese uqhumisa ukubunjwa kwefilimu encane, ebizwa ngokuthi ifilimu eshaywayo;Ngemva plasticizing extrusion, bese impahla encibilikisiwe kusukela isikhunta umlomo flow isandiso ukubumba ifilimu, ngokuthi flow extension ifilimu;Ifilimu eyenziwe ngezinto ezenziwe ngepulasitiki egoqwe ama-roller amaningana ku-calender ibizwa ngokuthi ifilimu ye-calendered.
