Mitundu ya mankhwala a PVC polyvinyl chloride imagawidwa mu PVC-SG3, PVC-SG5, PVC-SG8. Mitundu yosiyanasiyana ya mankhwala imakhala ndi ntchito zosiyanasiyana. Chigawo chapadera chogwiritsidwa ntchito ndi:
SG-3 ndi yamafilimu, mapaipi, zikopa, zingwe zamawaya ndi zinthu zina zofewa.
SG-5 ndi mapaipi, zopangira, mapanelo, kalendala, jakisoni, akamaumba, mbiri ndi nsapato.
SG-8 ndi mabotolo, mapepala, kalendala, jekeseni okhwima ndi mapaipi akamaumba.
Polyvinyl chloride ndi pulasitiki yofunikira yopanga yomwe ntchito zake zazikulu zimaphatikizapo:
1. Zipangizo zomangira: Mapulasitiki opangidwa ndi polyoxyethylene amagwiritsidwa ntchito kwambiri pomanga, monga kupanga mafelemu a mawindo, mapaipi, pansi ndi makoma, ndi zina zotero.
2. Mawaya ndi zingwe: Polyoxyethylene ndi zinthu zokhala ndi zinthu zabwino zotsekereza ndipo zimagwiritsidwa ntchito ngati chotchinga choteteza mawaya ndi zingwe.
3. Zida zoyikamo: Kuwonekera komanso kufewa kwa polyoxyethylene kumapangitsa kuti ikhale chisankho chabwino chopangira zinthu zosiyanasiyana, monga matumba apulasitiki, mabotolo, mitsuko, ndi zina zambiri.
4. Makampani agalimoto: Polyethylene imagwiritsidwa ntchito kwambiri popanga zida zamkati zamagalimoto, mapanelo oyenda, zophimba mipando ndi zida zina.
5. Zamankhwala: Zida za polyoxyethylene zimakhala ndi ntchito zofunika kwambiri pazida zamankhwala, monga machubu olowetsedwa, magolovesi opangira opaleshoni, matumba a magazi, ndi zina zotero.
6. Zinthu zapakhomo: Zinthu za polyoxyethylene monga zidebe zapulasitiki, mipando yapulasitiki, ndi zina zotero zimagwiritsidwa ntchito m’nyumba. Kukhalitsa kwawo ndi kuyeretsa kosavuta kumawapangitsa kukhala otchuka pakati pa ogula.
7. Zoseweretsa: Chifukwa cha chitetezo ndi kulimba kwa zinthu za polyoxyethylene, zimagwiritsidwa ntchito kwambiri popanga zoseweretsa za ana.
8. Dongosolo la mapaipi: Mapaipi a polyoxyethylene amagwiritsidwa ntchito kunyamula madzi, gasi kapena nthunzi m'minda monga ma projekiti osungira madzi, mafakitale a petrochemical, ndi kuteteza chilengedwe.
9. Zovala ndi nsapato: PVC ingagwiritsidwe ntchito kupanga malaya amvula opanda madzi ndi olimba, nsapato zamasewera, ndi zina zotero.
SG-3 ndi yamafilimu, mapaipi, zikopa, zingwe zamawaya ndi zinthu zina zofewa.
SG-5 ndi mapaipi, zopangira, mapanelo, kalendala, jakisoni, akamaumba, mbiri ndi nsapato.
SG-8 ndi mabotolo, mapepala, kalendala, jekeseni okhwima ndi mapaipi akamaumba.
