Nyocha banyere mmepe mmepe nke ụlọ ọrụ PVC (polyvinyl chloride) nke China na 2021, ikike mmepụta ga-eme ka ọ kwụsie ike.

1. Nchịkọta nke mmepe nke ụlọ ọrụ PVC

Polyvinyl chloride (PVC) bụ polymer kpụrụ site na polymerization nke vinyl chloride monomer (VCM) initiators dị ka peroxides na azo ogige ma ọ bụ n'okpuru omume nke ìhè na okpomọkụ dị ka usoro nke free radical polymerization.ngalaba dị mkpa.

A na-ekewa resins polyvinyl chloride n'ime resins izugbe na mado resins dị ka ojiji ha si dị: resins izugbe (G resins) bụ resins nke a na-agwakọta ya na ihe ndị na-emepụta plastik ma ọ bụ ihe mgbakwunye kwesịrị ekwesị iji mepụta ntụ ntụ ma ọ bụ mmiri mmiri maka nhazi;A na-ejikarị ihe eji eme ihe na-emepụta resins mado (P Resin) iji mepụta resin mado maka ojiji;e nwekwara resin ngwakọta nke PVC, nke bụ resin PVC nke na-anọchi akụkụ nke resin tapawa site na ịgwakọta mgbe ị na-emepụta plastisol PVC.

Isi nhazi nke resin PVC

Ụzọ isi mmepụta nke resin PVC gụnyere usoro nkwusioru, usoro nnukwu, usoro emulsion, usoro ngwọta na usoro micro-nkwusioru polymerization.Site n'echiche zuru ụwa ọnụ, usoro nkwusioru bụ isi mmepụta nke PVC n'ozuzu resin, ebe mmepụta nke PVC mado resin bụ emulsion usoro na micro-nkwusioru polymerization usoro.N'ihi usoro mmepụta dị iche iche, ikike mmepụta nke resin abụọ enweghị ike ịtụgharị n'ime ibe ha.

2. Ụlọ ọrụ mmepụta ihe nke ụlọ ọrụ PVC

Usoro mmepụta PVC bụ tumadi "usoro calcium carbide" na "usoro ethylene", na akụrụngwa ya bụ coal na mmanụ crude n'otu n'otu.Ọtụtụ mba n'ụwa na-eji ụzọ mmanụ na gas.N'ihi na China dara ogbenye na mmanụ yana ọgaranya coal, usoro mmepụta PVC nke obodo m na-adabere na usoro calcium carbide.

PVC ụlọ ọrụ yinye

Ngwa maka mmepụta PVC site na usoro calcium carbide bụ coal.Kemgbe afọ 2012, mmepụta coal sitere na mba m egosila usoro nke ọdịda mbụ wee na-abawanye.Dabere na National Bureau of Statistics, nrụpụta coal raw nke mba ga-eru ijeri tọn 4.13 na 2021, mmụba nke nde tọn 228 ma e jiri ya tụnyere 2020.

Ngwa maka mmepụta nke PVC site na usoro ethylene bụ mmanụ crude.Dị ka National Bureau of Statistics si kwuo, obodo m ga-emepụta 198.98 nde tọn mmanụ crude na 2021, mmụba nke 4.06 nde tọn ma e jiri ya tụnyere 2020. N'ime ha, 16.47 nde tọn mmanụ ka e mepụtara na December, otu afọ na- gbanwere +1.7%.
