Mkhalidwe wapakhomo ndi chitukuko chamakampani aku China a PVC

PVC ndi imodzi mwazinthu zisanu zapadziko lonse za utomoni, zomwe zimakhala ndi makhalidwe abwino kwambiri monga asidi ndi alkali kukana, kukana kuvala, kutsekemera kwamoto, ndi kutchinjiriza. Pakadali pano, yakhala yachiwiri yayikulu kwambiri padziko lonse lapansi pambuyo pa polyethylene.
1.Domestic kupanga mphamvu ndi kutulutsa kwa PVC
Kupanga kwa PVC kumaphatikizapo njira ziwiri: njira ya calcium carbide ndi njira ya ethylene, kusiyana kwakukulu kukhala njira yokonzekera vinyl kolorayidi monoma.
Malinga ndi zomwe zapanga m'zaka zaposachedwa, kupanga PVC kwawonetsa kuchulukirachulukira chaka ndi chaka, ndipo mphamvu zopanga zamakampani onse zalowa pachitukuko chanzeru. Pang'onopang'ono kuchuluka kwa msika kukuwonjezeka, ndipo kupanga kwawonjezeka pang'onopang'ono. Malinga ndi data yochokera ku China Chloroalkali Network, kuchuluka kwamakampani a PVC ku China kwakhalabe kupitilira 50% m'zaka zaposachedwa.
2. Njira Yachitukuko cha Makampani a PVC
(1) Limbikitsani ntchito yomanga zida zophatikizira mafakitale
Kuyambira 2007, dzikolo lapanga malamulo angapo omwe amapereka mwatsatanetsatane malamulo oyendetsera makampani a PVC. Nthawi yomweyo, imalimbikitsa kupanga zida zothandizira mabizinesi opangira ma calcium carbide ndi chlor alkali, komanso kulimbikitsa ntchito yomanga zida zophatikiza mafakitale. Motsogozedwa ndi ndondomeko za dziko lino, kukhazikitsidwa kwa zipangizo zophatikizira mafakitale kwakhala njira yosapeŵeka m’madera apakati ndi kumadzulo kwa dziko la China, amene ali ndi chuma cha malasha, migodi yamchere, ndi miyala ya laimu. Pansi pazida zophatikizika, podalira zabwino zazachuma komanso zabwino zofananira, ndalama zopangira zitha kuwongoleredwa bwino ndipo zopangira zingapo zitha kubwezeretsedwanso, Kupititsa patsogolo mpikisano wamsika komanso kupulumuka kwabizinesi.
(2) Njira zopangira zinthu zosiyanasiyana
Pachitukuko chamakono cha mabizinesi apakhomo a PVC, kugogomezera kusiyanasiyana kwa njira zopangira zida kumachulukirachulukira, zomwe zimapangitsa kuti zofunikira zawo pamlingo waukadaulo zichuluke kwambiri. Mchitidwe wa mitundu yosiyanasiyana sungathe kuyimitsa. Ndi kupititsa patsogolo njira zopangira zapakhomo za PVC, mabizinesi amayenera kugwiritsa ntchito pang'onopang'ono njira zatsopano zopangira ndikusunga njira yoyambirira ya calcium carbide. Pa nthawi yomweyo, PVC polymerization luso adzakhala kwambiri bwino, makamaka mawu a mphamvu yopanga polymerization riyakitala. Kuphatikiza apo, m'pofunikanso kuyambitsa ukadaulo wotsogola wakunja ndikuwalimbikitsa pang'onopang'ono kuti apititse patsogolo luso lazachuma lamakampani.
