Kalisiyumu karbide igiciro cyibikurura hasi mukuboza, hari itandukaniro ryakarere.Igiciro cyuruganda muri Wuhai na Ningxia cyaragabanutseho 100 yuan / toni.Bitewe n'ubwiyongere bwa karbide ya calcium no kugabanuka kw'ibisabwa kugira ngo yemere igiciro kinini, igiciro cyaragabanutse kugira ngo ibicuruzwa bigerweho.Igiciro cyubuguzi bwubushinwa bwamajyaruguru nu majyaruguru yuburasirazuba bwubushinwa bwagabanutseho 200 yuan / toni, cyane cyane ko igiciro cyambere cyaguzwe cyari kinini kandi igitutu cyacyo cyari kinini.Kugeza kuri 12.9, igiciro cyuruganda rwa calcium karbide muri Wuhai ni 3600 yuan / toni (ugereranije na -100 mu ntangiriro zukwezi).Hamwe no kugabanya ibiciro bya calcium karbide, ibiciro bimwe na bimwe bya calcium karbide byongeye gutakaza;Igiciro cyibikorwa bya PVC bifite calcium ya karbide yo hanze yagabanutse kandi igiciro cyaho cyazamutse, kandi igihombo cyibigo cyaragabanutse.Shandong ihuriweho na chlor-alkali yagabanije inyungu zayo kubera igabanuka rya chlorine y’amazi, kandi inyungu z’ibikoresho bya chlor-alkali bikomatanyije mu majyaruguru y’Ubushinwa biracyahari.Kugeza ubu, vinyl PVC inganda ziracyafite umwanya winyungu.Mugihe gito, hari impinduka nke mubiciro bya soda ya caustic mugihe cya vuba.Nubwo hari inzira igabanuka mu nyungu yo guhuza chlor-alkali, haracyari umwanya runaka winyungu.Kugeza ubu, uruganda ntirushaka kugabanya cyane umusaruro.

Icya gatatu, gusesengura kuruhande

kumanuka utangiye kugabanuka cyane ukwezi-ukwezi, komeza ukeneye kugura

Bitewe numubare muto wibyateganijwe, ishyaka ryo kumanuka ryo gutangira akazi rihora ari rito, kandi hamwe nubukonje bukabije, epfo izinjira mugihe cyigihe gito.Kugeza ku ya 9 Ukuboza, ubwubatsi bwatangiye kuri 43% (-12%) mu majyaruguru y’Ubushinwa, 50% (-18%) mu majyepfo y’Ubushinwa na 55% (-8%) mu majyepfo y’Ubushinwa.Muri rusange, nta kimenyetso cyiterambere mugukenera ibicuruzwa bya PVC kumanuka mugihe cya vuba.Kugura ibibanza birashobora gukomeza kwiganza byuzuzanya mubyumvikanyweho, kandi hashobora kubaho ububiko buke mbere yumunsi mukuru mubice bimwe.Muri rusange ibyifuzo bisabwa bizakomeza kuba intege nke.

Mu Kwakira, amakuru-yimbere yimitungo itimukanwa yakomeje gucika intege, kandi imikorere yo kurangiza yarangiye.Nubwo ikirere cya macro giheruka cyateye imbere kandi urwego rwimitungo itimukanwa rwongeye kugaragara, biracyatwara igihe cyo kugeza ku iherezo ryukuri rya PVC, kandi isoko riracyacuruza ibyateganijwe gusanwa amazu.Mu bice nyamukuru byamanuka, urwego rw'imiyoboro: rwungukiwe no guhindura politiki yo gukumira no kurwanya icyorezo mu gihe gito, ibigo bimwe na bimwe binini byagaruwe, kandi kubaka umuyoboro wa PVC byatejwe imbere gato.Nyamara, nkuko ibicuruzwa byinshi byamanutse byateganyaga kugira umunsi mukuru nyuma yumwaka mushya, amasoko mbisi ntiyakoraga.Isahani yerekana umwirondoro: imishinga mike mumajyaruguru irakira buhoro buhoro;Ubwubatsi bwamajyepfo nibyiza, komeza imikorere isanzwe mbere yiminsi mikuru ibiri, yose hamwe igera kuri 4-6%, ariko uruganda rukora umwirondoro ruracyafata ibikoresho fatizo hasi, igiciro kinini kiracyarwanya.Igorofa: Bitewe n’ubukungu bwifashe nabi mu mahanga hamwe n’ibarura ryinshi ry’ibicuruzwa byakozwe n’abacuruzi bo mu mahanga, ibyoherezwa mu mahanga bigabanuka.Inganda rusange, imitungo itimukanwa "imyambi itatu" kugirango izamure imitungo itimukanwa ntishobora gutera imbaraga mugihe gito, ibigo byibicuruzwa ntibyabonye ibisubizo byateganijwe.
