PVC S-1300 ntchito
PVC S-1300 ntchito,
PVC 1300 kwa bolodi mandala kusintha, PVC S-1300 ya chingwe, PVC S-1300 ya kanema,
Polyvinyl chloride (PVC) utomoni ndi mkulu polima opangidwa ndi polymerization wa ethylene.Kuyimitsidwa polymerization ntchito monga wamba mafakitale polymerization njira.Nthawi zambiri imakhala yolimba yomwe imatha kufewetsedwa ndi kutentha.Akatenthedwa, nthawi zambiri amakhala ndi kutentha kwa kutentha kapena kufewetsa, ndipo akhoza kukhala mu pulasitiki yotulutsa mpweya pansi pa mphamvu zakunja.Fakitale imatha kuwonjezera pulasitiki kapena othandizira ena kuti akwaniritse zofunikira zopanga malinga ndi zofunikira zamapulasitiki.
Kalasi S-1300 makamaka ntchito kupanga mkulu-mphamvu kusinthasintha mankhwala, mbamuikha zipangizo, okhwima ndi kusintha extrusion akamaumba ndi insulating zipangizo, etc. monga filimu woonda, mbale woonda, chikopa yokumba, waya, chingwe m'chimake ndi zofewa mitundu yonse ya mbiri.

Kugwiritsa ntchito
Kugwiritsa ntchito chingwe zinthu.Kugawa kwa ma molekyulu a utomoni wa PVC kumafunika kukhala koyenera pazosowa za zingwe zapamwamba.The makina katundu wa zinthu chingwe opangidwa ndi S-1300 ndi bwino.Ngakhale mphamvu ya dielectric ya S-1300 ndiyotsika pang'ono, imakhala yokulirapo kuposa zomwe zimafunikira pakuyika zida zotchingira chingwe.Chifukwa chake sizingakhudze kugwiritsidwa ntchito kwake pazinthu zoteteza.
Ntchito mu transparent flexible board.Pali mitundu yosiyanasiyana ya PVC matabwa zofewa pa msika, monga khomo makatani, nsalu tebulo, n'kupanga mvula zitseko galimoto ndi mazenera, etc. The mandala bolodi zofewa opangidwa bu S-1300 ali yosalala pamwamba, transparency zabwino, palibe pitting, ndi mfundo za kristalo zochepa.Ma transmittance, haze ndi yellow index ya S-1300 transparent flexible board ndiabwino kuposa index yamakampani, ndipo ili ndi makina abwinoko.
Ntchito mu mafilimu woonda.Mafilimu a PVC amatha kugawidwa mufilimu yaulimi, filimu ya calendered ndi filimu yotentha yotentha.Pakati pawo, filimu yowotcha kutentha imapangidwa makamaka ndi PVC yamtundu wa S-1300, pomwe filimu yaulimi ndi filimu yamakalendala imapangidwa makamaka ndi utomoni wa S-1300 PVC.Kanema wa kalendala wopangidwa ndi S-1300 ndi DOP plasticizer ali ndi mawonekedwe amphamvu yamakina apamwamba, kulimba kwabwino, kukana kwa alkali ndi kukana kuwonekera, kotero moyo wake wautumiki ndi wopitilira zaka zitatu.
