Kwiyongera k'ubushyuhe no kugabanuka bigomba kuba ingaruka zubushyuhe kurukuta rusange.Ubushyuhe bugira ingaruka ku kugabanuka, cyane cyane kuri PVC ikaze hamwe no kugabanuka.Kugabanuka kwa PVC yabumbwe ni 0.1-0.5%, naho kwaguka k'ubushyuhe n'ubushyuhe ni 70 ° C.Muyandi magambo, ibihumbi bitatu byavuzwe haruguru bishingiye kuriyi.
Ariko, dushobora kwirengagiza ko urukuta rwinjizwamo ari ubwoko bushya bwibintu byinshi hamwe nibikoresho byinshi bitandukanye, nkifu yimigano, fibre yimbaho nifu ya calcium, wongeyeho ibikoresho bikwiye byo gutunganya no gukanda bishyushye.Niba ibikoresho bibisi bigomba guhurizwa hamwe, bigomba kwihanganira ubushyuhe bwinshi.Nk’uko ubushakashatsi bubyerekana, ubushyuhe mu gihe cyo gukanda bushobora kugera kuri dogere 130.Amakuru afatika: Kwiyongera k'ubushyuhe n'ubushyuhe bwa PVC ni 70 ° C, ariko ubushyuhe bwo murugo mubusanzwe biragoye kurenga dogere 45, kandi biragoye kugera kubushyuhe bwo kwaguka no kugabanuka.Birashobora kuvugwa ko tudakeneye guhangayika.
Mubyongeyeho, ingano yifu ya calcium nifu yinkwi murukuta rwahujwe nabyo ni ikintu kigira ingaruka kumikorere yurukuta rwahujwe.Usibye kunoza imikorere yurukuta rwa monolithic kuva kuri formulaire, imiterere yibyimbye cyangwa ibinini byubu bikoreshwa murukuta rwa monolithic ubwayo nuburyo bwo kurwanya kwaguka.
Imikorere yibicuruzwa igomba gufatwa nkibisanzwe, ntabwo bivuye mubikorwa byibikoresho runaka.Kubwibyo, dukwiye gufata neza ibyo bita ibimenyetso byumva.Kugeza ubu, inganda zikomatanyirijwe hamwe zemewe buhoro buhoro na rubanda.Nibyo, urungano rwinshi ruzarwirwanya mubundi buryo.Igihe cyose ari ukuri, mubisanzwe bizakemuka.
