A: Katundu Polyvinyl kolorayidi ndi mkulu maselo polymerized ndi vinilu kolorayidi monoma (VCM) ndi structural element monga CH2-CHCLn, digiri ya polymerization zambiri monga 590-1500. polymerization ndondomeko, zinthu anachita, zikuchokera reactant, zina etc.it angatulutse eyiti mitundu yosiyanasiyana ya PVC utomoni ntchito ndi osiyana.Malinga ndi otsalira zili vinilu kolorayidi mu polyvinyl kolorayidi utomoni, akhoza kugawidwa mu: kalasi malonda, ukhondo chakudya kalasi ndi mankhwala ntchito kalasi mu maonekedwe, polyvinyl kolorayidi utomoni ndi ufa woyera kapena pellet.
B: Ntchito Polyvinyl kolorayidi utomoni chimagwiritsidwa ntchito popanga polyvinyl kolorayidi boardy leatheroid, utoto ndi zomatira wothandizira, tec.Utoto ndi zomatira .Division malinga ndi ntchito:
1.Zomangamanga: monga machubu a UPVC, mapaipi a UPVC, gulu ndi mipiringidzo yachigawo.
2.Packing zipangizo.
3.Zida zamagetsi: monga mawaya apakompyuta, zingwe, matepi omatira ndi mabawuti.
4.Furniture ndi zipangizo zokongoletsa, etc.
5.Others: leatheroid, mankhwala disposable mankhwala, antiseptic utoto, etc.
