Ikizamini cyimikorere ya reberi yibirunga ikubiyemo ibintu bikurikira

Ibikoresho bya reberi

Gupima imiterere ya tensile ya rubber
Ibicuruzwa byose bya reberi bikoreshwa mubihe bimwe byimbaraga zo hanze, birasabwa rero ko reberi igomba kuba ifite ibintu bimwe na bimwe bifatika ndetse nubukanishi, kandi imikorere igaragara ni imikorere idahwitse.Mugihe ukora igenzura ryibicuruzwa byarangiye, gushushanya ibikoresho bya reberi, kugena uko ibintu byifashe, no kugereranya ibisaza byashaje no guhangana hagati, birakenewe muri rusange gusuzuma imikorere idahwitse.Kubwibyo, imikorere idahwitse nimwe mubintu byingenzi bisanzwe bya reberi.

Imikorere ya tensile ikubiyemo ibintu bikurikira:

1. Guhangayikishwa cyane (S)
Imihangayiko iterwa nicyitegererezo mugihe cyo kurambura ni igipimo cyingufu zikoreshwa mukibanza cyambere cyambukiranya igice cyikigereranyo.

2. guhangayikishwa cyane no kuramba (Se)
Guhangayikishwa cyane aho igice cyakazi cyikigereranyo kirambuye kugeza igihe kirekire.Guhangayikishwa cyane harimo 100%, 200%, 300%, na 500%.

3. Imbaraga zingana (TS)
Impagarara ntarengwa ntarengwa aho urugero rurambuye kugirango rucike.Kera byitwa imbaraga zingutu nimbaraga zikaze.

4. Ijanisha ryo kuramba (E)
Guhindura igice cyakazi cyatewe nurugero rwa tensile ni igipimo cyo kwiyongera kuramba ku ijanisha ryambere ryuburebure.

5. Kurambura kumaganya runaka (Eg)
Kurambura ingero munsi yibibazo.

6. Kurambura kuruhuka (Eb)
Kurambura icyitegererezo mugihe cyo kuruhuka.

7. Kumena ihinduka rihoraho
Ongera urugero kugeza ruvunitse, hanyuma uhindurwe no guhindura ibintu bisigaye nyuma yigihe runaka (iminota 3) yo gukira muburyo bwubuntu.Agaciro ni igipimo cyo kwiyongera kurambuye igice cyakazi kuburebure bwambere.

8. Imbaraga zingana kuruhuka (TSb)
Imyitwarire idahwitse yikigereranyo cyacitse.Niba icyitegererezo gikomeje kuramba nyuma yumusaruro kandi kikaba kijyana no kugabanuka kwimyitwarire, indangagaciro za TS na TSb ziratandukanye, kandi agaciro ka TSb ni nto kurenza TS.

9. Guhangayikishwa cyane no gutanga umusaruro (Sy)
Guhangayikishwa bihuye ningingo ya mbere kumurongo uhangayikishije umurongo aho imbaraga ziyongera ariko imihangayiko ntiyongera.

10. Kurambura umusaruro (Ey)

Umunaniro (kurambura) uhuye ningingo ya mbere kumurongo uhangayikishije umurongo aho imbaraga ziyongera ariko guhangayika ntabwo byiyongera.

11. Gukuramo reberi ihindagurika rihoraho

Ibicuruzwa bimwe na bimwe bya reberi (nkibicuruzwa bifunga kashe) bikoreshwa muburyo bugabanijwe, kandi guhangana kwabo ni kimwe mubintu nyamukuru bigira ingaruka ku bwiza bwibicuruzwa.Kurwanya kwangirika kwa reberi mubisanzwe bipimwa no kwikuramo burundu.Iyo reberi iri muburyo bugabanijwe, byanze bikunze ihinduka ryumubiri nubumara.Iyo imbaraga zo guhonyora zabuze, izi mpinduka zibuza reberi gusubira uko yari imeze, bikaviramo guhindagurika guhoraho.Ubunini bwa compression ihoraho iterwa nubushyuhe nigihe cyo guhagarika imiterere, kimwe nubushyuhe nigihe uburebure bwagaruwe.Ku bushyuhe bwinshi, impinduka zimiti nimpamvu nyamukuru yo kwikuramo guhoraho kwa rubber.Ihindagurika rihoraho ripimwa nyuma yo gukuraho imbaraga zo gukanda zikoreshwa mukigereranyo no kugarura uburebure mubushyuhe busanzwe.Ku bushyuhe buke, impinduka ziterwa no gukomera kwikirahure no korohereza ibintu nibyo bintu nyamukuru mugupima.Iyo ubushyuhe buzamutse, izo ngaruka zirashira, birakenewe rero gupima uburebure bwikigereranyo ku bushyuhe bwikizamini.

Muri iki gihe hari amahame abiri y’igihugu yo gupima ihindagurika rihoraho rya reberi mu Bushinwa, aribyo kugena ihindagurika rihoraho ku bushyuhe bw’icyumba, ubushyuhe bwo hejuru, n’ubushyuhe buke kuri reberi y’ibirunga hamwe na reberi ya termoplastique (GB / T7759) nuburyo bwo kugena uburyo guhora guhindagurika kwihinduranya guhoraho kwa rubber (GB / T1683)
