Ururimi Muri Ibikorwa byumusaruro byinganda za reberi ya reberi na Vietnam Reberi , kugirango umenye imikorere ihamye mugihe cyo gutwara no gukora umurimo, kwitabwaho bidasanzwe byishyurwa kubungabunge no kubika ibidukikije.
1. Gukurura reberi iki? Ibimenyetso byo hejuru ni ibihe?
Mugihe cyo gutunganya, kubika, no gukoresha reberi nibicuruzwa byayo, imitungo yumubiri, imiti, hamwe nububiko bwa rebeni buragenda bwiyongera ku ngaruka zahujwe ningaruka zimbere zingaruka zimbere. Ihinduka ryitwa rubber ashaje. Ibimenyetso byayo byo hejuru birimo gucika, gukomera, gukomera, byoroshye, gukurura, guhinduranya, no kwagura.
2. Ni ibihe bintu bireba reberi ashaje?
Ibitera reberi gusa ni nkibi bikurikira:
(a) Ogisijeni: Iyo Rubber ihuye na ogisijeni, ibisubizo bya molekile bibaho, biganisha ku rubavu cyangwa guhunika gukabije kwambutse, bityo bihindura imikorere yacyo. Okidation nimpamvu nyamukuru itera reberi.
(b) Ozone: Ozone, ifite ibikorwa byinshi byimiti, birashobora kandi kwangiza iminyururu ya molekile. Cyane cyane iyo reberi iri muri leta yahinduwe, imiti ihagaritse izashingira, izwi nka "ozone yo gutontoma".
(c) Ubushyuhe: Kongera ubushyuhe bwihutisha igipimo cya okiside. Ibice byinshi bya rubber abakora (harimo inganda mu Bushinwa na Vietnam) bakora ibizamini byo gusaza ubushyuhe kugira ngo ibicuruzwa bikomeze gukora neza n'imbaraga no mu bushyuhe bwinshi.
(d) Urumuri: Imirasire ya ultraviolet irashobora guca iminyururu ya molekile cyangwa ibijyanye no guterana amagambo, bibera ahanini kumurongo wo hejuru.
(e) Guhangayikishwa: Guhangayikishwa kenshi bitera kwangirika iminyururu ya molekile no gutera amatekuma.
(f) Ubuhehere: Ubushuhe bushobora gusesa amatsinda ya hydrophilic muri reberi, yihutishije gusaza.
Byongeye kandi, izindi mpamvu zirimo ibitangazamakuru bya shimi, ion ivel, imirasire y'ingufu nyinshi, ingufu z'amashanyarazi, n'ibintu bya biologiya.
Ikirangantego cya Vietnam Mubisanzwe ukore kwigereranya niyi ngingo ukurikije ibisabwa byabigenewe byabakiriya batandukanye kugenzura umubare w'isoko.
3. Ni ibihe byiciro bya rubber ap agst ongera ugera?
(a) Uburyo bwo gusaza: Harimo gusaza ikirere, ubukana busanzwe bwo kubika, gusaza mu nyoni, gusaza ibinyabuzima, nibindi.
(b) Uburinzi bwihuse bwo kugerageza: Harimo gusaza, ozone gusaza, gusaza, ageze mu bihe bibi, gusaza ibinyabuzima, imirasire y'imisozi miremire, n'ibindi.
Mu nganda, Ibikoresho bya Rubber Ibyo bifite laboratoire ya CNAS bifite ubushobozi bwuzuye bwo gupima ubugari bwujuje ibigeragezo byabakiriya basanzwe basanzwe muri Automotive, ibikoresho bya elegitoroniki, ikimenyetso cyinganda, nindi mirima.
4. Guhitamo ubushyuhe bwa rubber ashyushye yo mu kirere
Kuri reberi karemano, ubushyuhe bwikizamini mubisanzwe 50-100 ℃; kuri reberi ya synthetic, ni 50-150 ℃ .Biza:
Nitrile Rubber: 70-150℃
Rubber: 200-300℃
VietIzina:se Ibice bya Rubber Mubisanzwe ukoreshe ibizamini byuburebure-hejuru yubushyuhe mugihe cyohereza ibicuruzwa byo mu Burayi na Amerika, mugihe Ibikoresho bya Rubber Gushyira mubikorwa ubushyuhe buke bwo kugenzura ukurikije ibintu bitandukanye bya Porogaramu (nko kuzenguruka ibishyimbo bya Automotive, akuramo amashusho ya elegitoroniki) kugirango yemeze ibipimo ngenderwaho mpuzamahanga.
Muri Ibikorwa byumusaruro byinganda za reberi ya reberi na Vietnam Reberi , kugirango umenye imikorere ihamye mugihe cyo gutwara no gukora umurimo, kwitabwaho bidasanzwe byishyurwa kubungabunge no kubika ibidukikije.
