Politiki ijyanye n'inganda za PVC

Muri Werurwe 2021, Akarere k’imbere mu gihugu cya Mongoliya kasohoye ku mugaragaro “Ingamba nyinshi z’ingwate zo kwemeza ko irangizwa rya“ Gahunda y’imyaka 14 y’imyaka itanu ”ikoreshwa ry’ingufu zikoreshwa mu kugenzura no kugenzura."Ibipimo" bisaba ko urukurikirane rw'inganda zikoresha ingufu nyinshi nka PVC, soda caustic, na ivu rya soda bitazongera kwemerwa mugihe cy "gahunda yimyaka 14 yimyaka 5".Niba ari ngombwa kongera ubushobozi bushya bwo kubyaza umusaruro, kugabanya no gusimbuza ubushobozi bw’umusaruro no gukoresha ingufu bigomba gukorwa.Ibi bivuze ko ubushobozi bwa PVC buzaza mu karere ka Mongoliya Yigenga, Intara nini y’ingufu, bizagabanuka gusa ariko ntibiyongera.Imbere muri Mongoliya nintara nini y’umusaruro wa PVC mu gihugu cyanjye.Intara yose y’amajyaruguru y’iburengerazuba ifite 49.2% by’umusaruro w’igihugu, mu gihe Mongoliya yo mu gihugu igera kuri 37% by’umusaruro w’akarere k’amajyaruguru y’iburengerazuba, cyangwa hafi 18.2% y’ubushobozi bw’igihugu.

5, iterambere ryinganda za PVC

Mu myaka 10 iri imbere, inganda za PVC zo mu gihugu zizakomeza kuva ku isoko maze zinjire muri parike, zimenyekanishe hamwe mu nganda, guhindura imiterere y’imiterere y’inganda, no korohereza imikoreshereze y’ibikoresho n’ibikoresho bizaba ari byiza guhuza imishinga kugira ngo ibone inyungu kandi yunguke. inyungu zo guhatanira.Mu nzira nyabagendwa, kubana kwa kariside ya calcium hamwe nuburyo bwa Ethylene bizakomeza, ariko igipimo cyuburyo bwa Ethylene kizagenda cyaguka, buhoro buhoro gikureho guterwa nuburyo bwa acetylene, kandi gitange umusanzu mwiza mukugabanya kwanduza ibidukikije. no kugera ku majyambere arambye.Jiang Zhongfa y'ubu izaba uruhande rwiza, ariko igomba kugenzurwa numusaruro nyirizina.

Muri make, inganda za PVC zizagenda zituza buhoro buhoro kandi zishyire mu gaciro mu gihe cy’umutekano muke no kurengera ibidukikije, mu isoko rikaze ndetse n’ipiganwa ry’ibiciro, ndetse no guhindura buhoro buhoro ubushobozi bw’umusaruro urenze.Iterambere ryiza kandi ryujuje ubuziranenge, ubushobozi bwo kubyaza umusaruro buzibanda mu turere two ku nkombe n’iburengerazuba, kandi ibikorwa binini kandi byambukiranya akarere bizahinduka inzira nyamukuru.Ibi birashobora kugaragara uhereye kumyumvire yubushobozi bwumusaruro wimbere mu gihugu mumyaka yashize.Impinduka zihamye mubushobozi bwumusaruro akenshi zigaragaza gushyira mu gaciro iterambere ryinganda.Muri icyo gihe, ibintu bitateganijwe ku isoko byazanye ingaruka z'igihe gito ku iterambere ry’inganda, cyane cyane ingaruka z’icyorezo cy’icyorezo, kigira ingaruka ku buryo butaziguye, kigira ingaruka ku isano riri hagati y’ibitangwa n’ibisabwa, bigerageza iterambere ry’iterambere inganda, kandi izana amahirwe mu nganda, ndetse no mu gihe cy’icyorezo nyuma y’icyorezo, itandukaniro mu turere dutandukanye ryazanye inyungu z’agateganyo mu turere tumwe na tumwe.Nyuma yisesengura ryumvikana, ibuka kwagura buhumyi no kwangiriza igipimo cyubushobozi bwumusaruro n’ibisohoka, kandi witondere cyane kuzamura ireme no kugabanya ibicuruzwa.Kunoza imyanda yihariye, yihariye kandi yihariye irashobora kuba icyerekezo cyingenzi cyiterambere ryinganda zimwe na zimwe za PVC mugihe kizaza.

Iterambere rya PVC mu Bushinwa ririmo guhinduka kuva mu binini kugera ku bikomeye, biva ku bicuruzwa byo mu rwego rwo hasi bikagera ku bicuruzwa byo mu rwego rwo hejuru, kuva mu koroshya ibintu bitandukanye, ariko haracyari inzira ndende yo kuva mu gihugu kinini cya PVC kikagera ku mbaraga zitanga umusaruro. .Ibigo bya PVC nabyo bigomba kongera ubushobozi bwigenga bwo guhanga udushya no kongera kubaka amakipe yimpano.Kuva ku bikoresho fatizo bifasha gutunganya ibikoresho, kugenzura ibikorwa, kugeza kubipfunyika no gutwara ibintu, hanyuma kugeza kubicuruzwa bitunganijwe neza, iterambere no kuzamura ubuzima bwose.Kugera kumugenzuzi wo hasi no hejuru, guteza imbere ubwuzuzanye niterambere rusange hamwe niterambere, kugirango tugere ku iterambere ryiza ryiza ryiterambere ryinganda, no gutanga umusanzu wimbaraga zinganda za chlor-alkali kugirango ubumenyi bwinganda n’ikoranabuhanga mu iterambere ry’igihugu ndetse n’ingufu z’inganda.
