Nibihe bintu biranga EPDM reberi?

1. Ubucucike buke kandi bwuzuye
Ethylene-propylene reberi ni reberi ifite ubucucike bwo hasi, hamwe nubucucike bwa 0.87. Byongeye kandi, birashobora kuzuzwa namavuta menshi na EPDM.
Ongeraho kuzungura birashobora kugabanya ikiguzi cyibicuruzwa bya rubber no guhimba igiciro kinini cya proceylene reberi ya reberi. Kuri Ethylene Procoylene reberi hamwe nagaciro keza gahore, imbaraga z'umubiri nubuka ryuzuye zo kuzungurira hejuru ntabwo zaragabanutse cyane.

2. Kurwanya
Ethylene-propayne Rubber ifite uburyo bwiza bwo kurwanya ikirere, ozone, kurwanya ubushyuhe, itandukaniro rya aside, imitungo yuzuye, imitungo y'amazi n'amashanyarazi mu cyumba cy'ubushyuhe. Ethylene-Proceyle Ibicuruzwa bya Rubber birashobora gukoreshwa igihe kirekire saa 120 ° C, kandi birashobora gukoreshwa muri make cyangwa rimwe na rimwe kuri 150-200 ° C. Ongeraho antioxiday irashobora kongera ubushyuhe. EPDM REBER CROSS-ihujwe na peroxide irashobora gukoreshwa mubihe bibi. EPDM RUBBER irashobora kugera ku birenga 150h idacika mu bihe bya Ozone Kwibandaho 50pphm na 30% birambuye.

3. Kurwanya Ruswa
Kubera ko Ethylene Propaylene Rubber ibuze polarite nurwego rwo hasi yubusa, bufite imbaraga nziza mumiti itandukanye nka alcool, amavuta, amavuta, ketones, ketones. Ariko ifite ituze ribi cyane mubinure na aromatic (nka lisansi, bezene, benzene, nibindi) namavuta ya minisiteri. Imikorere nayo izagabanuka mu gikorwa kirekire cyo kwibanda kuri Acide. Muri ISO / kugeza 7620, ubwoko bugera kuri 400 bwimiti ya gaze ya ruseke hamwe namazi yakusanyije amakuru atandukanye, hanyuma yerekanwe urwego rwa rubber zitandukanye, kandi rwerekanwe murwego rwa 1-4 kugirango yerekane urwego rwibikorwa, kandi ingaruka z'imiti ya rubrosive kuri reberi.

Icyiciro cyo kunanirwa kubyimba /% kugabanya agaciro ingaruka kumikorere
1 <10 <10 gake cyangwa oya
2 10-20 <20 nto
3 30-60 <30 Hagati
4> 60> 30 bikabije

4. Kurwanya Vaport
Ethylene-propylene reberi ifite umwuka mwiza wamazi yo kurwanya kandi bikaba byiza kuruta kurwanya ubushyuhe. Muri 230 ℃ Steam Steam yishimye, isura ya EPDM yakomeje guhinduka nyuma ya 100h. Ariko, mubihe bimwe, Fluorine Rubber, Silicone Rubber, Fluosilikone Rubber, Butyl Rubber, Buber Rubber, nitrile reberi, na reberi karemano yibasiye ibintu bigufi nyuma yigihe gito.

5. Kurwanya amazi arenze
Ethylene-propylene reberi nayo irwanya neza amazi akomeye, ariko bifitanye isano rya bugufi na sisitemu zose zivuguruzanya. Ethylene-propylene reberi hamwe na dimorhone deteulfide na TMTD nka sisitemu yo gutuza, nyuma yo kwibizwa mumazi akomeye kuri 125 ° C amezi 15, igipimo cya mashini gihinduka gito cyane, kandi igipimo cya mashini ni 0.3% gusa.

6. Imikorere y'amashanyarazi
Ethylene-propayne Rubber ifite umuhanga mwiza w'amashanyarazi hamwe no kurwanya corona, kandi imitungo yayo iruta cyangwa hafi ya polyethlene, CHLORUSNES COLYeNONE, CHLOROSHYLENE, CHLOSHYLENES NA COLYethne na COLYethylene.

7. Guhinduka
Kuberako nta bisobanuro bya polar biri mumiterere ya molefulane ya rolefulani ya reberi, imbaraga zubumwe za molekile ni hasi, kandi urunigi rwa molekile rushobora gukomeza guhinduka hamwe na butadiene reberi isanzwe.

8. Adhesion
Ethy-propayne Rubber ibura amatsinda akomeye kubera imiterere yacyo kandi afite imbaraga zoroheje. Byongeye kandi, rubber biroroshye kubyina, kandi kwiyagira no kwiyambaza no guhimba kwawufite ubukene cyane.
