ntchito

POLYVINYL CHLORIDE FILM, yopangidwa ndiPVC utomonindi ma modifiers ena kudzera mu kalendala kapena kuumba njira.Makulidwe ambiri ndi 0.08 ~ 0.2mm, wamkulu kuposa 0.25mm wotchedwa PVC pepala.Pulasitiki, stabilizer, lubricant ndi zina zinchito processing AIDS ndi anawonjezera PVC utomoni, ndi filimu amapangidwa ndi calendering.

Kanema wa PVC atha kugawidwa m'magulu awiri, imodzi ndi Filimu ya PVC Yopangidwa ndi Plasticized, yomwe imadziwikanso kuti Filimu yofewa ya PVC, inayo ndi Filimu ya PVC Yopanda pulasitiki, yomwe imadziwikanso kuti hard PVC Film.

Pakati pawo, PVC yolimba imakhala pafupifupi 2/3 yamsika, ndi akaunti yofewa ya PVC ya 1/3.PVC yofewa nthawi zambiri imagwiritsidwa ntchito pansi, padenga ndi pachikopa, koma chifukwa PVC yofewa imakhala ndi zofewa (ichinso ndi kusiyana pakati pa PVC yofewa ndi PVC yolimba), yosavuta kukhala yowonongeka, yosavuta kusunga, kotero kuti ntchito yake ndi yochepa. .PVC yolimba ilibe zofewa, motero imakhala ndi kusinthasintha kwabwino, kuumba kosavuta, kosavuta kukwapula, kopanda poizoni komanso kopanda kuipitsidwa, kusungitsa nthawi yayitali, kotero imakhala ndi chitukuko chachikulu komanso mtengo wogwiritsa ntchito.Chofunika kwambiri cha filimu ya PVC ndi filimu ya vacuum blister, yomwe imagwiritsidwa ntchito popanga mapepala amtundu uliwonse, choncho imadziwikanso kuti filimu yokongoletsera, filimu yomatira, yomwe imagwiritsidwa ntchito pomanga, kulongedza, mankhwala ndi mafakitale ena ambiri.Pakati pawo, makampani opanga zida zomangira amakhala gawo lalikulu kwambiri la 60%, ndikutsatiridwa ndi makampani onyamula katundu, palinso ntchito zina zazing'ono zamakampaniwo.

⑴ Malinga ndi zopangira zomwe zimagwiritsidwa ntchito popanga filimu: filimu ya polyethylene, filimu ya polypropylene, filimu ya polyvinyl chloride ndi filimu ya polyester.

(2) Gulu pogwiritsa ntchito filimu: filimu yaulimi (pano molingana ndi ntchito yeniyeni ya filimu yaulimi, ikhoza kugawidwa mu filimu ya pulasitiki ndi filimu yowonjezera kutentha);Packaging film (PACKAGING filimu molingana ndi momwe amagwiritsidwira ntchito, ndipo imatha kugawidwa kukhala filimu yopangira chakudya ndi filimu yopangira zinthu zosiyanasiyana zamafakitale, etc.) komanso malo apadera, pogwiritsa ntchito filimu yopumira, filimu yosungunuka m'madzi ndi filimu ya piezoelectric. .

(3) Malinga ndi filimu akamaumba njira gulu: extrusion plasticization, ndiyeno kuwomba akamaumba filimu, wotchedwa kuwomba akamaumba filimu;Pambuyo extrusion plasticization, ndiyeno osungunula zakuthupi otaya ku nkhungu pakamwa kupanga filimu, wotchedwa otaya filimu;Mu calendering makina ndi masikono angapo adagulung'undisa plasticizing zipangizo zopangidwa filimu, wotchedwa calendering filimu.

Kugwiritsa ntchito filimu ya PVC
