Ibiranga reberi ya nitrile na EPDM reberi hamwe nubwiza bwa reberi

1. Nitrile rubber
Rubber ya Nitrile ikoreshwa cyane mugukora ibicuruzwa byangiza amavuta.NBR muri make, reberi yubukorikori ikozwe na copolymerizing butadiene na acrylonitrile.Ni reberi ya sintetike ifite amavuta meza (cyane cyane amavuta ya alkane) hamwe no gusaza.
Rubber ya Nitrile ikorwa na emulsion polymerisation ya butadiene na acrylonitrile.Rubber ya Nitrile ikorwa ahanini nubushyuhe bwo hasi bwa emulion polymerisation.Ifite amavuta meza cyane, irwanya kwambara cyane, irwanya ubushyuhe bwiza hamwe no gukomera..
Ingaruka zayo ni ubukonje buke buke, kwihanganira ozone, imikorere idahwitse, hamwe na elastique nkeya.Irashobora gukoreshwa igihe kirekire mu kirere kuri 120 ° C cyangwa mu mavuta kuri 150 ° C.
Byongeye kandi, ifite kandi imbaraga zo kurwanya amazi, gukomera kwumwuka no gukora neza, kandi ikoreshwa cyane mugukora ibicuruzwa bitandukanye byangiza amavuta.

Rubber
Rubber ya EPDM nuburyo butari inkingi, bwuzuye.Ibyo bita "non-polar" bivuze ko molekile zigize polymer zitarimo amatsinda ya polar.Ibyo bita "kwiyuzuzamo" bivuze ko molekile zigize polymer zidafite imvano ebyiri.
EPDM (Ethylene propylene diene monomer), nk'ubwoko bwa reberi ifite ubuhanga bworoshye, kwambara, kurwanya ubushyuhe, kurwanya ikirere, kurwanya ozone, amazi meza n'amazi yo mu nyanja, byakoreshejwe cyane mu bikoresho bya reberi ku modoka.

3. Nigute ushobora kumenya niba hose ya reberi ari nziza cyangwa mbi?
Reba hejuru ya reberi ya reberi: Mubusanzwe hariho ubwoko bubiri bwa reberi, ubuso bunoze hamwe nigitambara.Ubuso bunoze busaba ubuso butagira ibibyimba nibisohoka;ubuso bwanditse busaba umwenda uzengurutse kuba uringaniye kandi intera imwe.
Reba urwego rwo gushimangira: urwego rwo gushimangira ruzengurutswe na fibre hamwe ninsinga z'ibyuma.Ibice byinshi, niko igitutu cyakiriwe, nintego yingenzi yo kuvangura.
Reba niba hose ya reberi idasanzwe: mugihe gisanzwe, reberi ya rubber iri mumuzingi wuzuye.Niba ari elliptique cyangwa idatunganijwe neza, irashobora kugira ingaruka kumikoreshereze ya rubber.
Reba imikorere yunamye ya reberi ya reberi: kugoreka hose hagati, witegereze ibara ryubuso hamwe nubwihuta bwisubiramo, ihinduka ryibara ni rito, kandi umuvuduko wo kwihuta urihuta, byerekana ko ubwiza bwa hose ari bwiza.
