Iterambere ry'Inganda za Polyvinyl Chloride CAS9002-86-2 Rikurura Abantu, Kandi Isoko Ritanga Icyitegererezo Gitandukanye

Vuba aha, polyvinyl chloride (PVC), ibikoresho bifite umwanya ukomeye mu nganda zikora imiti, byongeye kuba intandaro y’inganda. Iterambere ry’iterambere mu musaruro wabyo, ikoreshwa ryabyo, n’imiterere y’isoko byakuruye abantu benshi. Nk’uko raporo zibigaragaza, ku ruhande rw’umusaruro, nk’imwe mu nganda zikora polyvinyl chloride ku isi, Ubushinwa bwabonye ibigo byinshi binini bikora imiti bikomeza kongera ishoramari ryabyo no kuvugurura ikoranabuhanga ryabyo ku mishinga ikora polyvinyl chloride vuba aha. Zhong'an, Jinan, Shandong Chemical Group yatangaje mu ntangiriro z’uku kwezi ko yarangije neza umushinga wo guhindura ibintu mu buryo bw’ubwenge mu ivugururwa ryayo rya polyvinyl chloride. Binyuze mu gutangiza sisitemu zigezweho zo kugenzura ibintu mu buryo bwikora n’ibikoresho bitanga umusaruro mwinshi, ntibyazamuye gusa umusaruro, hamwe n’umusaruro witezweho kwiyongera kwa 30% buri mwaka, ahubwo byanagabanyije neza ikoreshwa ry’ingufu n’imyuka ihumanya, bigeraho iterambere rishya mu musaruro utari uwangiza ibidukikije. Iki cyemezo kandi kigaragaza ubushakashatsi bw’ibigo biri mu nganda ziriho ubu kugira ngo byongere ubushobozi bwo gukora no kunoza inzira z’umusaruro, bigamije gufata umwanya mwiza mu ipiganwa rikomeye ku isoko. Mu rwego rwo gukoresha, polyvinyl chloride, ishingiye ku miterere yayo myiza y’umubiri n’imiti, ikomeje kwagura isoko ryayo. Inganda z’ubwubatsi zikomeje kuba zo zikoresha polyvinyl chloride nyinshi, kandi ikoreshwa cyane mu moko atandukanye y’imiyoboro, imiyoboro, n’ibikoresho byo gushushanya inyubako. Bitewe n’iterambere rirambye ry’ubwubatsi bw’ibikorwa remezo by’igihugu no kuzamuka buhoro buhoro kw’isoko ry’ubutaka, icyifuzo cy’ibicuruzwa bya polyvinyl chloride kigaragaza iterambere rihoraho. Urugero, mu mushinga mugari uherutse kubakwa mu mujyi wa [City Name], imiyoboro myinshi ikomeye kandi irwanya gusaza ya polyvinyl chloride yakoreshejwe mu gutanga amazi n’imiyoboro y’amazi, kandi ikigereranyo cyayo cyiza cyo kuramba no gukoresha ikiguzi cyashimwe cyane n’umushinga. Byongeye kandi, polyvinyl chloride nayo iri kuzamuka mu nzego zikiri kuzamuka nko mu buvuzi no mu by’ikoranabuhanga. Mu rwego rw’ubuvuzi, polyvinyl chloride ivurwa by’umwihariko ikoreshwa cyane mu gukora ibikoresho byo kwa muganga nk’imifuka yo guteramo amaraso, imifuka y’amaraso, na catheter zo kwa muganga. Kubera ko ifite ubwisanzure, ubworoherane, kandi ihuza ubuzima n’ibinyabuzima, itanga uburyo bwo korohereza ibikorwa by’ubuvuzi kandi ikanizeza umutekano w’abarwayi. Mu rwego rw'ikoranabuhanga, polyvinyl chloride, nk'igikoresho gikingira insinga n'insinga, cyishingikiriza ku mikorere yacyo myiza yo gukingira amashanyarazi no kurwanya ingese, bituma ibikoresho by'ikoranabuhanga bikomeza gukora neza, bihaza ibyifuzo by'inganda zigezweho zikora ibikoresho by'ikoranabuhanga bigezweho. Ariko, iterambere ry'inganda za polyvinyl chloride ntirigenda neza. Mu gihe habayeho gukabya gukenera kurengera ibidukikije, ibibazo by'imyanda nka vinyl chloride monomer ishobora gukorwa mu gihe cyo gukora polyvinyl chloride biri munsi y'ubuyobozi bukomeye. Kugira ngo bahangane n'iki kibazo, amashyirahamwe y'inganda ashyiraho ibigo bigamije guhanahana ikoranabuhanga ryo kurengera ibidukikije no guhugura, bashishikariza ibigo gukoresha ikoranabuhanga rigezweho ryo gukora ibintu bisukuye, nk'uburyo bwo gukamura umwuka mu buryo bwa gaze, gutunganya cyane imyuka ihumanya kugira ngo ibyuka bihumanya ikirere byujuje ibisabwa. Muri icyo gihe, uturere tumwe na tumwe twashyizeho politiki zijyanye n'inganda, zitanga inkunga y'imari n'imisoro ku bigo bikora kuvugurura kurengera ibidukikije, bigaha inganda impinduka mu iterambere rirambye kandi rirambye. Ku bijyanye n'isoko, igiciro cya polyvinyl chloride cyarahindutse ku rugero runaka vuba aha. Bitewe n'ibintu bitandukanye nko guhinduka kw'ibiciro bya peteroli mpuzamahanga, imiterere y'itangwa ry'ibikoresho fatizo, n'impinduka mu ikoreshwa ry'ibikomoka ku bimera, igiciro cy'igihe kizaza cya polyvinyl chloride cyabanje kuzamuka, hanyuma kikagabanuka, hanyuma kikaza guhagarara mu kwezi gushize. Abasesenguzi b'inganda bavuga ko nubwo hari ukudasobanutse neza mu izamuka ry'ibiciro muri iki gihe, mu gihe kirekire, hamwe no kuzamuka kw'ubukungu bw'isi no gukomeza kwaguka kw'ibigo bishya bikoresha, amahirwe yo ku isoko rya polyvinyl chloride aracyari manini, kandi byitezwe ko igiciro gishobora kuguma gihamye mu rugero rukwiye kandi kikagaragaza izamuka riri hagati mu mwaka utaha. Muri rusange, mu gihe hari amahirwe n'imbogamizi, inganda za polyvinyl chloride zirimo guharanira kugera ku iterambere ryazo ryiza binyuze mu ngamba zitandukanye nko guhanga udushya mu ikoranabuhanga, kwagura ikoreshwa, no kuvugurura uburyo bwo kurengera ibidukikije. Iterambere ryazo ry'igihe kizaza nta gushidikanya ko rizagira ingaruka zikomeye ku nganda zikora imiti n'izindi nganda zikora imiti.
