Ibicuruzwa bya PVC bikoreshwa cyane mubuzima bwa buri munsi, ariko birashobora no kugira ibibazo mugihe cyo gukoresha.Uyu munsi, uwakozeSainuo ibishashara bya polyethyleneizagutwara kwiga kubyerekeye ikibazo cyera cyibicuruzwa bya PVC.

Iyo ibicuruzwa bya PVC bihuye nubushyuhe bwo hanze, bitewe ningaruka zubushuhe, dioxyde de carbone, dioxyde de sulfure, n’umucyo mu kirere, bazerekana ibintu byera, bitewe ahanini nimpamvu eshatu zikurikira:
1. Kwera nyuma yo kwibizwa mu mazi
Ubwoko bwinshi bwibicuruzwa bya PVC bibonerana byerekana igihu cyera iyo uhuye namazi cyangwa amavuta mugihe kirekire.Ibicuruzwa byoroshye birakomeye kuruta ibikomeye.Bitewe no kwibiza mumazi, plasitike, stabilisateur, nibindi bigwa muri PVC hanyuma bigahinduka hydrata, bigakora imvura ihindagurika hejuru (bigira ingaruka kumucyo).Nubwo amazi yatose yaba yagiye, plasitike na stabilisateur ntibishobora gusubizwa uko byahoze.Gusa nukwongera ubushyuhe burashobora guhuza ubwuzuzanye hagati ya plasitike na stabilisateur mbere yuko bisubirana.
2. Kwera nyuma yo guhura nizuba
Ibicuruzwa bya PVC byerekanwe nizuba hanze birashobora kandi kwerekana umweru bitewe ningaruka zubushuhe, dioxyde de carbone, dioxyde de sulfure, numucyo mwikirere.Ibi bifitanye isano no guhuza stabilisateur.Mu masabune yicyuma, benzoates ihujwe neza na PVC yerekana umweru muke ugereranije na stearates.Amabati kama ntago yoroshye kwera, kandi amabati kama arimo sulfure nibyiza cyane, agakurikirwa nu munyu wa acide lauric hamwe nu munyu wa manate.Ongeramo urumuri rwumucyo, ester ya fosifite, stabilisateur yamazi, nibindi birashobora gukumira cyangwa kugabanya ibintu byera bya PVC biterwa no guhura nizuba.

Ibicuruzwa bikomeye bya PVC bizahinduka umweru nyuma yo kugaragara muri Floride cyangwa ahandi hantu hatose, ariko ntibizakomeza kuba umweru iyo bigaragaye muri Arizona.Ubushuhe rero ni ibintu biteza umweru PVC guhura nizuba.
3. Shimangira umweru
Guhangayikishwa na Stress bivuga ibintu byera mu bice by’ibicuruzwa bya PVC, nko kunama, gukonjesha, no kurambura, bitewe nimbaraga ziva hanze.
Ibi birashobora guterwa no guhindura imiterere ya molekuline iterwa nimbaraga zo hanze, icyerekezo cyumunyururu wa polymer, ihinduka ryubucucike bwa PVC, hamwe no kugaragara kwubusa hagati ya molekile zimwe na zimwe kugirango habeho gukwirakwiza urumuri, bigatuma ibicuruzwa bya PVC bigaragara ko byera.

4. Ibindi byera
Mugihe cyo gutunganya ibicuruzwa bibonerana bya PVC, niba hakoreshejwe amavuta menshi cyane, imvura nyinshi irashobora kandi gutuma ibicuruzwa bibonerana bitanga umusaruro wera, rimwe na rimwe byitwa kwera.
Ibi bintu byera mubisanzwe bivamo ibishashara bigaragara nkibintu hejuru yibicuruzwa.Igisubizo nukugabanya umubare wamavuta yakoreshejwe cyangwa ugahindura amavuta hamwe neza, kugirango ugere kuburinganire hagati yimbere ninyuma yo kwisiga.
Kubindi bisobanuro, nyamuneka twandikire!
