Kuwunika kwa chitukuko chamakampani aku China a PVC (polyvinyl chloride) mu 2021, mphamvu zopanga zidzakhazikika.

Kuwunika kwa chitukuko chamakampani aku China a PVC (polyvinyl chloride) mu 2021, mphamvu zopanga zidzakhazikika.

1. Chidule cha chitukuko cha makampani a PVC

Polyvinyl kolorayidi (PVC) ndi polima opangidwa ndi polymerization wa vinilu kolorayidi monoma (VCM) mu intiators monga peroxides ndi azo mankhwala kapena pansi pa zochita za kuwala ndi kutentha malinga ndi limagwirira ufulu kwakukulu ma polymerization.gulu lofunika.

Ma resins a polyvinyl chloride amagawidwa makamaka kukhala ma resins opangidwa ndi cholinga chambiri ndikuyika utomoni molingana ndi momwe amagwiritsidwira ntchito: ma resins acholinga chonse (G resins) ndi ma resins omwe amasakanizidwa ndi kuchuluka kwabwino kwa mapulasitiki kapena zowonjezera kuti apange ufa wouma kapena wonyowa kuti upangidwe;phala resin (P Resin) nthawi zambiri amapangidwa ndi plasticizer kupanga phala utomoni ntchito;palinso utomoni wosakanikirana wa PVC, womwe ndi utomoni wa PVC womwe umalowa m'malo mwa utomoni wa phala posakaniza popanga PVC plastisol.

Gulu lalikulu la utomoni wa PVC

Waukulu kupanga njira PVC utomoni monga kuyimitsidwa njira, njira chochuluka, njira emulsion, njira yothetsera ndi yaying'ono kuyimitsidwa polymerization njira.Padziko lonse, kuyimitsidwa njira ndi waukulu kupanga njira PVC ambiri cholinga utomoni, pamene njira kupanga PVC phala utomoni ndi emulsion njira ndi yaying'ono kuyimitsidwa polymerization njira.Chifukwa cha njira zosiyanasiyana zopangira, mphamvu yopangira ma resin awiriwo sangasinthidwe wina ndi mnzake.

2. Unyolo wamakampani amakampani a PVC

Njira yopangira PVC makamaka ndi "njira ya calcium carbide" ndi "njira ya ethylene", ndipo zida zake ndi malasha ndi mafuta opanda mafuta motsatana.Mayiko ambiri padziko lapansi amagwiritsa ntchito njira yamafuta ndi gasi.Chifukwa dziko la China ndi losauka ndi mafuta komanso malasha ochuluka, njira yopangira PVC ya dziko langa imachokera ku njira ya calcium carbide.

PVC makampani unyolo

Zopangira zopangira PVC ndi njira ya calcium carbide ndi malasha.Kuyambira 2012, kutulutsa kwa malasha akuda mdziko langa kwawonetsa kutsika koyamba ndikuwonjezeka.Malinga ndi National Bureau of Statistics, kutulutsa kwa malasha kudziko lonse kudzafika matani 4.13 biliyoni mu 2021, kuwonjezeka kwa matani 228 miliyoni poyerekeza ndi 2020.

Zopangira zopangira PVC ndi njira ya ethylene ndi mafuta opanda mafuta.Malinga ndi National Bureau of Statistics, dziko langa lidzatulutsa matani 198.98 miliyoni amafuta osakanizidwa mu 2021, kuchuluka kwa matani 4.06 miliyoni poyerekeza ndi 2020. Mwa iwo, matani 16.47 miliyoni amafuta osakanizidwa adapangidwa mu Disembala, chaka-ku- kuwonjezeka kwa chaka ndi 1.7%.
