Uburyo butandukanye busanzwe bwo kumenya irabu

1. Ikizamini cyo kudakora ku rugero rwo hagati mu kongera ibiro

Igicuruzwa cyarangiye gishobora gupimwa, kikanigwa mu kintu kimwe cyangwa byinshi byatoranijwe, kigapimwa nyuma y'ubushyuhe n'igihe runaka, kandi ubwoko bw'ibikoresho bushobora gufatwa hakurikijwe igipimo cy'impinduka z'uburemere n'igipimo cy'impinduka z'ubukomere.

Urugero, mu mavuta ya dogere 100 mu gihe cy'amasaha 24, NBR, fluorine rubber, ECO, CR bifite impinduka nto mu bwiza no mu bukomere, mu gihe NR, EPDM, SBR yikuba kabiri ibiro kandi ihinduka cyane mu bukomere, kandi ingano yo kwaguka iragaragara.

2. Ikizamini cyo gusaza umwuka ushyushye

Fata ingero z'ibicuruzwa byarangiye, ubishyire mu gasanduku k'izabukuru umunsi umwe, hanyuma urebe uko ibintu bimeze nyuma yo gusaza. Gusaza buhoro buhoro bishobora kwiyongera buhoro buhoro. Urugero, CR, NR, na SBR bizacika intege kuri dogere 150, mu gihe NBR EPDM ikiri irashya. Iyo ubushyuhe buzamutse bukagera kuri dogere 180, NBR isanzwe izaba irashya cyane; naho HNBR nayo izaba irashya cyane kuri dogere 230, kandi rubber ya fluorine na silicone biracyafite ubushyuhe bwiza.

3. Uburyo bwo gutwika

Fata urugero ruto urutwike mu kirere. Reba uko ibintu bimeze.

Muri rusange, fluorine rubber, CR, CSM nta muriro urimo, kandi nubwo umuriro waba urimo kwaka, ni muto cyane ugereranyije na NR rusange na EPDM. Birumvikana ko iyo turebye neza, imiterere y'umuriro, ibara, n'impumuro nabyo biduha amakuru menshi. Urugero, iyo NBR/PVC ihujwe na kole, iyo hari isoko y'umuriro, umuriro urasandara kandi usa n'aho ari amazi. Tugomba kumenya ko rimwe na rimwe kole igabanya umuriro ariko idafite halogen nayo izimya umuriro, ibyo bikaba bigomba gusobanurwa n'ubundi buryo.

4. Gupima uburemere bwihariye

Koresha igipimo cy'ikoranabuhanga cyangwa uburyo bwo gusesengura, bungana na garama 0.01, wongereho ikirahure cy'amazi n'umusatsi.

Muri rusange, fluorine rubber ifite uburemere bunini cyane, buri hejuru ya 1.8, kandi ibyinshi mu bicuruzwa bya CR ECO bifite igipimo kinini kiri hejuru ya 1.3. Izi kole zishobora kwitabwaho.

5. Uburyo bw'ubushyuhe buri hasi

Fata urugero rw'ibicuruzwa byarangiye ukoreshe urubura rwumye na alcool kugira ngo ubone ahantu hakwiriye ho gushyuha. Shyira urugero mu bushyuhe buke mu gihe cy'iminota 2-5, wumve uburyo bworoshye n'ubukomere ku bushyuhe bwatoranijwe. Urugero, kuri dogere -40, ubushyuhe bwinshi n'ubudahangarwa bw'amavuta ya silica gel na fluorine rubber biragereranywa, maze silica gel iba yoroshye.
