Filimu ya polyvinyl chloride imapangidwa ndi utomoni wa polyvinyl chloride ndi zosintha zina kudzera munjira yopangira kalendala kapena kuumba nkhonya. Makulidwe ambiri ndi 0.08 ~ 0.2mm, ndipo chilichonse choposa 0.25mm chimatchedwa pepala la PVC. Zida zogwirira ntchito monga mapulasitiki, zolimbitsa thupi, ndi zothira mafuta zimawonjezeredwa ku utomoni wa PVC ndikukulungidwa mufilimu.
Gulu la Mafilimu a PVC
Mafilimu a polyvinyl chloride (PVC Film) akhoza kugawidwa m'magulu awiri, imodzi ndi filimu ya PVC yapulasitiki, ndipo ina ndi filimu ya PVC yopanda pulasitiki.
Pakati pawo, PVC yolimba imakhala pafupifupi 2/3 yamsika, ndi akaunti yofewa ya PVC ya 1/3. PVC yofewa nthawi zambiri imagwiritsidwa ntchito popanga pansi, kudenga komanso pamwamba pa zikopa. Komabe, chifukwa PVC yofewa imakhala ndi zofewa (izi ndizosiyananso pakati pa PVC yofewa ndi PVC yolimba), zimakhala zosavuta komanso zovuta kuzisunga, kotero kuti ntchito yake ndi yochepa. PVC yolimba ilibe zofewa, choncho imakhala ndi kusinthasintha kwabwino, ndi yosavuta kuumba, osati yowonongeka, yopanda poizoni komanso yosaipitsa, ndipo imakhala ndi nthawi yayitali yosungira, choncho imakhala ndi chitukuko chachikulu ndi ntchito. Chofunika kwambiri cha filimu ya PVC ndi filimu yowonongeka ndi pulasitiki, yomwe imagwiritsidwa ntchito poyikapo mitundu yosiyanasiyana ya mapanelo. Choncho, imatchedwanso kukongoletsa filimu ndi zomatira filimu. Amagwiritsidwa ntchito m'mafakitale ambiri monga zomangira, kulongedza katundu, mankhwala, ndi zina zambiri. Pakati pawo, makampani opanga zida zomangira amawerengera gawo lalikulu, ndikutsatiridwa ndi makampani onyamula katundu, ndi mafakitale ena angapo ang'onoang'ono.
⑴ Gulu molingana ndi zida zomwe zimagwiritsidwa ntchito popanga filimu: filimu ya polyethylene, filimu ya polypropylene, filimu ya polyvinyl chloride ndi filimu ya polyester, ndi zina.
⑵ Gulu pogwiritsa ntchito mafilimu: Pali mafilimu aulimi (makanema aulimi amatha kugawidwa m'mafilimu a mulch ndi mafilimu owonjezera kutentha malinga ndi ntchito zawo); mafilimu onyamula (makanema onyamula amatha kugawidwa m'mafilimu opangira chakudya ndi zinthu zosiyanasiyana zamafakitale malinga ndi momwe amagwiritsidwira ntchito). filimu yonyamula katundu, ndi zina zotero) ndi mafilimu opumira kwa malo apadera ndi zolinga zapadera, mafilimu osungunuka m'madzi ndi mafilimu okhala ndi piezoelectric properties, etc.
⑶ Osankhidwa molingana ndi njira yopangira mafilimu: pali mafilimu omwe amapangidwa ndi pulasitiki ndi extrusion kenako amawumbidwa, omwe amatchedwa mafilimu owombera; Mafilimu omwe amapangidwa ndi pulasitiki ndi extrusion ndiyeno amapangidwa ndi zinthu zosungunuka kuchokera kukamwa kwa nkhungu amatchedwa mafilimu oponyedwa. ; Kanema wopangidwa ndi zinthu zopangidwa ndi pulasitiki zopindidwa ndi ma roller angapo pa kalendala amatchedwa filimu ya calendered.
Kugwiritsa Ntchito Mafilimu a PVC
Kawirikawiri, tepi yaikulu kwambiri imagwiritsidwa ntchito pamagetsi. Malingana ndi makhalidwe ake, angagwiritsidwe ntchito pa tepi yotetezera, tepi ya katundu, tepi yozindikiritsa, zomata zotsatsa, tepi ya payipi, etc. Amagwiritsidwanso ntchito kwambiri pamoyo watsiku ndi tsiku, monga nsapato, zidole, malaya amvula, nsalu za tebulo, maambulera, ulimi. mafilimu, etc.
Kanema wamba wamba wa PVC wowonjezera kutentha: Palibe zowonjezera zoletsa kukalamba zomwe zimawonjezeredwa panthawi yopanga filimuyo. Moyo wothandizira ndi miyezi 4 mpaka 6. Ikhoza kutulutsa nyengo imodzi ya mbewu. Pakali pano ikutha.
Filimu ya PVC yoletsa kukalamba: Zowonjezera zoletsa kukalamba zimawonjezeredwa kuzinthu zopangira ndikukulungidwa mufilimu. Ili ndi nthawi yogwiritsira ntchito bwino ya miyezi 8 mpaka 10 ndipo imakhala ndi kuwala kwabwino, kuteteza kutentha komanso kukana nyengo.
Zinthu zokongoletsera za PVC: Zili ndi anti-kukalamba komanso kudontha, kuwala kwabwino komanso kutchinjiriza kwamafuta. Imatha kudontha kwa miyezi 4 mpaka 6 ndipo imakhala ndi moyo wotetezeka wa miyezi 12 mpaka 18. Imagwiritsidwa ntchito kwambiri ndipo pakadali pano ndiyothandiza kwambiri. Nyumba zosungiramo mphamvu zowonjezera dzuwa zimakutidwa ndi zida.
Kanema wa PVC wosagwirizana ndi nyengo komanso wosagwetsa fumbi: Kuphatikiza pa kugonjetsedwa ndi nyengo komanso kusagwa, pamwamba pa filimuyi adathandizidwa kuti achepetse mvula ya plasticizer komanso kuyamwa pang'ono fumbi, zomwe zimathandizira kufalikira kwa kuwala komanso kopindulitsa. kulima kwa dzinja ndi masika m'malo obiriwira a dzuwa.
PVC itha kugwiritsidwanso ntchito ngati mulch filimu, ndipo mtundu wina wa masterbatch ukhoza kuwonjezeredwa kuti apange mafilimu okhetsedwa amitundu yosiyanasiyana.
PVC zojambulazo: pulasitiki, zitsulo, mandala filimu, sanali pepala ma CD, ma CD pulasitiki, ma CD matabwa, ma CD zitsulo, etc.
