1 、Gutanga impande zombi zituma ubushakashatsi bwiyongera

Hagati kugeza mu mpera za Werurwe, hamwe no gusohora amakuru yo kubungabunga ibikoresho byinshi bya PC nka Hainan Huasheng, Shengtong Juyuan, na Dafeng Jiangning, hari ibimenyetso byiza ku isoko ry’isoko. Iyi myiyerekano yatumye isoko ryiyongera ryiyongera, aho abakora PC bongera ibicuruzwa byabo ku ruganda 200-300 Yuan / toni. Ariko, nkuko twinjiye muri Mata, ingaruka nziza zigihe cyashize zagiye zigabanuka buhoro buhoro, kandi ibiciro byaho ntibyakomeje kuzamuka, bituma isoko ryiyongera kumasoko. Byongeye kandi, hamwe nigiciro gito cyibikoresho fatizo, ibiciro bimwe na bimwe byaragabanutse, kandi abitabiriye isoko bafata imyifatire yo gutegereza no kubona isoko ryigihe kizaza.

2 、Igiciro gito cyibikoresho fatizo bisphenol A ifite inkunga ntarengwa kubiciro bya PC

Igiciro cyibikoresho fatizo bisphenol A byakomeje kuba hasi vuba, nubwo inkunga ikomeye ituruka hejuru ya benzene yuzuye, imikorere yibitangwa nibisabwa ntabwo ishimishije. Ku bijyanye no gutanga, ibice bimwe bya bispenol A bizakomeza kubungabungwa cyangwa kugabanuka muri Mata, kandi hari gahunda yo kongera ubushobozi bw’umusaruro, ushobora kongera umusaruro. Kubijyanye nibisabwa, kubera gufata nabi ibikoresho bya PC kugiti cye hamwe no gukenera epoxy resin terminal, icyifuzo cyo hasi cyibice bibiri byingenzi bigize bispenol A cyaragabanutse. Munsi yumukino wo gutanga no gusaba nigiciro, biteganijwe ko igiciro cya bisphenol A kizakomeza kwerekana ihindagurika ryintera mugihe cyanyuma, hamwe nigiciro gito kuri PC.

3 、Imikorere yibikoresho bya PC irahagaze neza, kandi inyungu zo kubungabunga zigenda zigabanuka buhoro buhoro

Duhereye ku mikorere iheruka y'ibikoresho bya PC mu Bushinwa, abayikora benshi bagaragaje imikorere ihamye y'ibikoresho byabo. Mugihe Hainan Huasheng yinjiye mugihe cyo kubungabunga, igipimo cyo gukoresha ubushobozi bwa PC cyaragabanutse, ukwezi kwagabanutseho 3.83%, ariko umwaka ushize kwiyongera 10.85%. Byongeye kandi, igikoresho cya PC cya Shengtong Juyuan nacyo giteganijwe kubungabungwa mu mpera za Mata. Nyamara, ingaruka nziza zazanywe nubu bugenzuzi zashyizwe ahagaragara mbere, kandi ingaruka zazo ku isoko zigenda zigabanuka buhoro buhoro. Hagati aho, ku isoko hari ibihuha bivuga ko uruganda rwa PC rwa Hengli Petrochemical ruzatangira gukoreshwa mu mpera z'ukwezi. Niba amakuru ari ayukuri, irashobora kuzana imbaraga kumasoko ya PC.

Iterambere rya vuba mubikoresho bya PC murugo

4 、Gutinda buhoro mugukoresha PC kugaragara no gushyigikirwa bikenewe

Dukurikije imibare y'ibarurishamibare kuva muri Mutarama kugeza Werurwe, igipimo cyo gukoresha ubushobozi mu nganda za PC zo mu gihugu cyarushijeho gutera imbere, ku buryo umusaruro wiyongereye ku mwaka ku mwaka. Nyamara, habaye igabanuka rikabije ry’ibicuruzwa byatumijwe mu mahanga, bituma habaho iterambere rito mu bicuruzwa bigaragara. Imiterere yinyungu yinganda za PC zo murugo zateye imbere cyane mugihembwe cya mbere, hamwe nababikora bongera umusaruro nibikoresho bikora neza. Nubwo, nubwo ibicuruzwa byo hasi bifite ibyifuzo byiza, ibyifuzo bikenerwa kuri PC biragoye kuba inkunga ikomeye yo gutwara isoko.

5 、Isoko rya PC ryigihe gito rishobora kwibanda cyane cyane ku guhuriza hamwe ifaranga nyuma yimikorere

Ukurikije isesengura ryavuzwe haruguru, haracyari inkunga yo gutanga isoko ku isoko rya PC iriho, ariko igitutu cyibiciro nibisabwa ntigishobora kwirengagizwa. Igiciro gito cyibikoresho fatizo bisphenol A ifite inkunga ntarengwa kubiciro bya PC; Nyamara, kwiyongera kumikoreshereze yiterambere biratinda, bigatuma bigora gutanga inkunga ikomeye. Kubwibyo, biteganijwe ko mugihe gito, isoko rya PC rishobora kwibanda cyane cyane ku guhuriza hamwe isoko ryimikorere
