Amakuru yimitungo itimukanwa arahagarikwa nabi, kandi PVC iroroha.

Ku wa mbere, amakuru y’imitungo itimukanwa yakomeje kuba umunebwe, ibyo bikaba byaragize ingaruka mbi ku biteganijwe.Mugihe cyo gusoza, amasezerano nyamukuru ya PVC yagabanutse hejuru ya 2%.Mu cyumweru gishize, amakuru yo muri Amerika CPI muri Nyakanga yari make ugereranije n’uko byari byitezwe, ibyo bikaba byongera ubushake bw’abashoramari.Muri icyo gihe, byari biteganijwe ko icyifuzo cya zahabu, icyenda cya feza n’ibihe icumi by’impinga byariyongereye, bitanga inkunga ku biciro.Nyamara, isoko ifite gushidikanya kubyerekeye kugarura umutekano kuruhande rwibisabwa.Ubwiyongere bwazanywe no kugarura ibyifuzo byimbere mu gihugu mugihe giciriritse nigihe kirekire ntibishobora guhagarika ubwiyongere bwazanywe no kugarura ibicuruzwa no kugabanuka kubisabwa bizanwa nibisabwa hanze bitewe nigitutu cyubukungu.Nyuma, irashobora gutuma izamuka ryibiciro byibicuruzwa, kandi hamwe n’ibiteganijwe ko ifaranga ryongera kwiyongera, ntibishoboka ko igipimo cy’inyungu cya Federasiyo cya Federasiyo kizagabanuka cyane, ibyo bikaba binashyiraho igitutu ku biciro bya disiki.

Icyibanze, ibyateganijwe ku isoko rya PVC byahindutse ubusa, ariko ntahantu henshi hagaragara twavuga mugihe gito.Muri iki cyumweru, ubwubatsi bwa PVC bwatangiye kugabanuka gato, kandi impinga yo kubungabunga yararangiye.Mubyiciro byambere, kubera impamvu zo kubungabunga ibihe, ibikoresho bya parikingi byasubukuye umusaruro umwe umwe, kandi biteganijwe ko uruhande rutanga ruzakira.Nyamara, uburyo bwa calcium karbide yumushinga uburyo bumwe bwo gutakaza inyungu, gutangira kubaka birahagarikwa, kandi uruhande rusabwa ni rwinshi.Bigaragarira mubyifuzo byisoko, kubera ingaruka ziheruka ziterwa nigihembwe cyimbere mugihugu no guhashya icyorezo no kugabanuka kwicyifuzo cyo hanze bitewe nigitutu cyubukungu, ibikorwa byo hasi birashishoza, bikomeza injyana yo kuzuza ibikenewe gusa, bikavamo kwiyongera mubarura rusange ryimbere mu gihugu, aribyo gukurura ibiciro., Nubwo igiciro cya disiki cyagabanutse munsi yikiguzi cyamabuye yo hanze ya calcium karbide ya karbide V, ibyingenzi byo guhanagura buhoro buhoro margin biragoye guteza imbere guhora kwa disiki, ariko bitewe nigiciro gito gishyigikira igiciro kiri munsi, kugabanuka kwigihe gito nabyo bigarukira.

Muri rusange, ibintu bitesha umutwe byatumye ibiciro bikomeza kwiyongera mubyiciro byambere byagabanutse kumwanya uriho.Nyuma yicyiciro giheruka kuzamuka, igabanuka ryamakuru yimitungo itimukanwa ryashyizeho igitutu kinini kubiciro.Mugihe zahabu mugihe gito, icyenda, ifeza, hamwe nigihe cyigihe cyo gukoresha cyegereje, hari ibyifuzo byiterambere mubisabwa.Guhindura ibisabwa mugihe gito bizaba intandaro yinzibacyuho iheruka.Witondere kunoza ibisabwa.Biteganijwe ko igiciro cyigihe gito kizakomeza guhindagurika.
