ntchito

Imadziwika kuti POLYVINYL CHLORIDE FILM, imapangidwa ndiPVC utomonindi zosintha zina pogwiritsa ntchito calendering kapena kuwomba kuumba.Makulidwe ambiri ndi 0.08 ~ 0.2mm, wamkulu kuposa 0.25mm wotchedwa PVC pepala.PVC utomoni anawonjezera plasticizer, stabilizer, lubricant ndi zina zinchito processing AIDS, calendering filimu.

Mtundu uwu wa kukhetsa filimu kutentha kuteteza, kuwala transmittance ndi zabwino, zofewa ndi zosavuta mawonekedwe, oyenera wowonjezera kutentha, wowonjezera kutentha ndi yaing'ono okhetsedwa kunja chophimba zakuthupi.

Zoyipa ndizo: gawo lotsika la filimu, kukwera mtengo;Kusauka kwa nyengo, kulimba komanso kuphulika pa kutentha kochepa, kosavuta kufewetsa ndi kumasuka pa kutentha kwakukulu;Pambuyo mpweya wa zina, filimu padziko vacuuming, zimakhudza kufala kuwala;Zotsalira filimu si degradable ndi kuyaka mankhwala.

Filimu ya PVC ikhoza kugawidwa m'magulu awiri, imodzi ndi Filimu ya Plasticized PVC, yomwe imadziwikanso kuti Filimu yofewa ya PVC (Filimu ya PVC Yopangidwa ndi Plasticized), inayo si Filimu ya PVC ya Plasticized, yomwe imadziwikanso kuti Filimu ya PVC Yolimba (Filimu ya PVC Yopanda pulasitiki) Pakati pawo, Nkhani zolimba za PVC zimakhala pafupifupi 2/3 ya msika, ndi akaunti zosinthika za PVC za 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 kupulumutsa, kotero ntchito yake ndi yochepa Yovuta. PVC alibe wothandizila zofewetsa, kotero kusinthasintha, akamaumba zosavuta, osati Chimaona, sanali poizoni kuipitsa-free, kupulumutsa nthawi yaitali, kotero chitukuko ndi ntchito mtengo wapatali wa PVC filimu akamanena za zingalowe chithuza filimu, ntchito mitundu yonse ya gulu pamwamba wosanjikiza ma CD, omwe amadziwikanso kuti kukongoletsa filimu Gwirizanitsani filimu, ntchito zomangira ma CD mankhwala, ndi mafakitale ena ambiri Makampani zomangira ndi gawo lalikulu, 60%, kutsatiridwa ndi makampani ma CD, pali zina zingapo zing'onozing'ono zomwe zimagwiritsidwa ntchito pamakampani molingana ndi filimuyo kupanga gulu lazopangira: filimu ya polyethylene, filimu ya polypropylene, filimu ya PVC ndi filimu ya poliyesitala Malinga ndi gulu la ntchito filimu: filimu yaulimi (pano malinga ndi ntchito yeniyeni ya filimu yaulimi, akhoza kugawidwa mu mulching filimu ndi wowonjezera kutentha filimu);Ma CD filimu (ma CD filimu malinga ndi zolinga zawo zenizeni, ndipo akhoza kugawidwa mu filimu chakudya ma CD ndi mitundu yonse ya mankhwala mafakitale ndi ma CD filimu, etc.) ntchito ya piezoelectric woonda filimu ndi zina zotero Malinga ndi kupanga njira za gulu filimu: extrusion plasticizing Ndiye kuwomba akamaumba wa woonda filimu, wotchedwa filimu kuwombedwa;Pambuyo extrusion plasticizing, ndiyeno osungunula zinthu kuchokera nkhungu pakamwa otaya kutambasuka akamaumba filimu, wotchedwa otaya kutambasuka filimu;Kanema wopangidwa ndi zinthu zapulasitiki zokulungidwa ndi zodzigudubuza zingapo pa kalendala amatchedwa filimu ya calendered.
