Ni irihe tandukaniro riri hagati ya EPDM n'ibikoresho bya NBR / PVC?

Gusobanukirwa itandukaniro riri hagati ya EPDM (Ethylene propylene diene monomer) na NBR / PVC (nitrile butadiene rubber / polyvinyl chloride) ni ngombwa muguhitamo ibikoresho bikoreshwa muburyo butandukanye, cyane cyane mubikorwa nkimodoka, ubwubatsi, ninganda. Ibikoresho byombi bitanga imitungo idasanzwe ituma ikoreshwa neza, kandi gusobanukirwa itandukaniro birashobora kugufasha gufata ibyemezo byuzuye.

Ibigize hamwe nimiterere

Ethylene propylene diene monomer (EPDM) ni reberi yubukorikori izwiho kurwanya cyane ubushyuhe, ozone, nikirere. Ibigize Ethylene, propylene, na diene biha imiterere yihariye. EPDM nziza cyane nubushobozi bwo guhangana nubushyuhe bukabije bituma ihitamo neza kubisabwa hanze. Irwanya kandi UV- kandi idashobora gusaza, bigatuma ihitamo gukundwa no gusakara ibisenge, kashe, na gasketi.

Kurundi ruhande, NBR (nitrile butadiene rubber) ni reberi yubukorikori igizwe ahanini na acrylonitrile na butadiene. Uku guhuriza hamwe guha NBR amavuta meza na peteroli birwanya, bigatuma iba ibikoresho byatoranijwe kumavuta ya peteroli, kashe, na gasketi mu nganda zitwara ibinyabiziga. Nubwo atari reberi, PVC (polyvinyl chloride) ni thermoplastique ikoreshwa cyane kandi irwanya imiti kandi iramba. Bikunze gukoreshwa mumiyoboro, kubika insinga, hamwe nubwubatsi butandukanye.

Kurwanya ubushyuhe

Kimwe mu bintu byingenzi bitandukanya EPDM na NBR / PVC ni ukurwanya ubushyuhe bwabo. EPDM irashobora kwihanganira ubushyuhe buri hagati ya -40 ° F na 250 ° F (-40 ° C kugeza 121 ° C), bigatuma ibera ahantu henshi. Ibinyuranye, NBR ifite ubushyuhe buke, mubisanzwe ikora neza hagati ya -40 ° F na 212 ° F (-40 ° C kugeza 100 ° C). Mugihe PVC ikoreshwa cyane, ifite ubushyuhe buke kandi ikunda gucika kubushyuhe buke.

Kurwanya imiti

Ku bijyanye no kurwanya imiti, NBR igaragara cyane mu kurwanya amavuta, lisansi, n’ibindi bicuruzwa bishingiye kuri peteroli. Ibi bituma ihitamo neza kubisabwa mu nganda zitwara ibinyabiziga n’ikirere. Mugihe EPDM irwanya imiti myinshi, ikora nabi mubijyanye no kurwanya amavuta na lisansi. Ku rundi ruhande, PVC irwanya imiti myinshi y’imiti ariko irashobora guterwa n’imiti imwe n'amavuta.

EPDM na NBR / PVC bifite porogaramu zitandukanye cyane kubera imiterere yihariye. EPDM isanzwe ikoreshwa muri sisitemu yo gusakara, guhindagura ibinyabiziga, no kubika amashanyarazi. Kuramba kwayo no kurwanya ibintu bidukikije bituma ihitamo neza kubisabwa hanze. NBR ikoreshwa cyane cyane mu nganda zitwara ibinyabiziga zikoreshwa na peteroli na peteroli nka gasketi, kashe, hamwe na hose. PVC, kubera imbaraga zayo nuburyo bwinshi, ikoreshwa cyane mukubaka imiyoboro, ibikoresho, hamwe n’amashanyarazi.

Ibiciro

Igiciro nikindi kintu ugomba gusuzuma muguhitamo hagati ya EPDM na NBR / PVC. Mubisanzwe, EPDM ikunda kuba ihenze kuruta NBR kubera imiterere yayo isumba iyindi n'imikorere mubidukikije bikaze. PVC akenshi nuburyo buhendutse cyane, bigatuma ihitamo gukundwa kubikorwa byimishinga.

Ubwanyuma, guhitamo hagati ya EPDM na NBR / PVC biterwa ahanini nibisabwa byihariye bya porogaramu. EPDM nibyiza kubikorwa byo hanze bisaba guhangana nikirere cyiza, mugihe NBR aribintu byatoranijwe kugirango amavuta na peteroli birwanya amamodoka. PVC itanga ibintu byinshi kandi ikora neza, yujuje ibyifuzo byinshi byubwubatsi. Gusobanukirwa itandukaniro birashobora gufasha injeniyeri, ababikora, nabaguzi gufata ibyemezo byuzuye bijyanye nibikorwa byabo.
