PVA
Katundu: Polyvinyl alcohol (PVA)
CAS#:9002-89-5
Fomula ya maselo: C2H4O
Fomula Yopangira Kapangidwe:
Ntchito: Monga mtundu wa utomoni wosungunuka, umagwira ntchito makamaka popanga ndi kugwirizanitsa filimu. Umagwiritsidwa ntchito kwambiri mu kukula kwa nsalu, zomatira, zomangamanga, zopangira kukula kwa mapepala, zokutira utoto, mafilimu ndi mafakitale ena.
Mawonekedwe
1. Kukhazikika kwa kutentha komanso kukana nyengo. OB-1 ingagwiritsidwebe ntchito kutentha kwambiri. Kukana kutentha kwambiri ndi chimodzi mwa zinthu zabwino kwambiri zoyeretsera.
2. Kapangidwe kake koyera: OB-1 ili ndi mphamvu yabwino kwambiri yoyera. Imatha kubwezera mtundu wachikasu wosafunikira womwe uli mu substrate ndikuwunikira kuwala kowoneka bwino, zomwe zimapangitsa kuti zinthuzo ziwoneke zoyera, zowala komanso zowala kwambiri.
3. Kuthamanga kwabwino kwa utoto. OB-1 imachita bwino kwambiri poyeretsa utoto, ndipo zinthu zoyera sizivuta kutaya mtundu.
4. OB-1 imagwirizana bwino ndi ma polima ambiri. Ndi chinthu choyeretsera pulasitiki chomwe chimagwiritsidwa ntchito kwambiri komanso chimapereka ndalama zambiri zogulira.
5. Kuwala kwakukulu kwa kuwala. OB-1 ndi yoyenera kusakanikirana ndi mitundu ina kuti ipange mphamvu yogwirizana.
6. Kuchuluka kwa OB-1 komwe kwawonjezeredwa sikuyenera kupitirira chiŵerengero cha pamwamba. Kugwiritsidwa ntchito, kuchuluka kwa OB-1 komwe kwawonjezeredwa kumakhala kochepa, ndipo mvula imatuluka mosavuta ikagwiritsidwa ntchito mopitirira muyeso.
Ntchito:
OB-1 imagwiritsidwa ntchito poyeretsa madzi a polyester, makamaka poyeretsa ulusi wa polyester ndi kuyeretsa polyester ndi thonje ndi nsalu zina zosakanikirana, komanso poyeretsa zinthu zapulasitiki.
1. Chogulitsachi ndi choyenera kuyeretsa ulusi wa polyester, ulusi wa nayiloni, ulusi wa polypropylene ndi ulusi wina wa mankhwala.
2. Chogulitsachi ndi choyenera kuyeretsa ndi kuunikira pulasitiki ya polypropylene, ABS, EVA, polystyrene, polycarbonate, ndi zina zotero.
3. Chogulitsachi ndi choyenera kuwonjezera polimeri yachizolowezi ya polyester ndi nayiloni.
4. Ndi yoyenera makamaka kuyeretsa zinthu zapulasitiki zomwe zimapangidwa kutentha kwambiri.
