NBR muaj cov roj ua haujlwm zoo, EPDM tsis zoo hauv cov roj ua haujlwm thiab tsis ruaj khov, tab sis nws tuaj yeem tiv taus kev laus thiab kub.Feem ntau, EPDM feem ntau yog siv rau cov kav dej thiab tshaj chav dej;EPDM yog zoo dua nyob rau hauv kev sib txhuam tsis kam.
1. Nitrile roj hmab NBR yog polar unsaturated carbon saw roj hmab, uas yog copolymerized los ntawm acrylonitrile thiab butadiene.Nyob ntawm cov ntsiab lus ntawm acrylonitrile los ntawm qis mus rau siab, cov roj kuj tau txhim kho, tab sis qhov txias tsis kam yog txo.
Roj tsis kam yog qhov loj tshaj plaws ntawm NBR nitrile roj hmab, uas muaj kev tiv thaiv zoo rau cov roj av-raws li cov roj thiab cov kuab tshuaj uas tsis yog-polar, tab sis tsis zoo tiv thaiv cov roj polar thiab polar solvents.
1. Zoo antistatic khoom;
2. Tsis zoo ozone tsis kam;
3. Nws muaj kev sib raug zoo nrog cov khoom siv polar, xws li polyvinyl chloride (PVC), polyoxymethylene (POM), nylon, thiab tuaj yeem ua rau cov khoom siv roj hmab thiab yas.
4. Kev khiav hauj lwm kub ntawm cov roj hmab nitrile zoo tib yam: -20 ° C ~ 120 ° C, thiab qhov kub tsis kam tiv taus ntau yam tuaj yeem qis dua -50 ° C;
2. Ethylene-propylene roj hmab siv ethylene thiab propylene ua cov khoom siv hluavtaws, thiab tuaj yeem muab faib ua binary ethylene-propylene roj hmab (EPM) thiab tertiary ethylene-propylene roj hmab (EPDM).
Cov khoom ntawm ethylene propylene roj hmab:
1. Ozone aging kuj
2. Huab cua tsis kam
3. Thaum tshav kub kub tsis kam
Cov khoom saum toj no peb yog qhov zoo tshaj plaws hauv cov roj hmab dav dav.Kuj tseem muaj cov khoom nram qab no
4. Dej tsis kam, superheat kuj thiab dej vapor kuj;
5. Cov tshuaj tiv thaiv zoo heev;
(Vim tias cov tshuaj lom neeg ruaj khov thiab tsis muaj polarity ntawm ethylene-propylene roj hmab nws tus kheej, nws tsis chemically react nrog cov tshuaj feem ntau, nws yog incompatibility los yog me ntsis compatibility nrog polar tshuaj, thiab nws yog resistant rau cawv, acid, muaj zog alkali, oxidizing. Cov tshuaj ntxuav tes, tsiaj txhu thiab zaub roj, ketones, thiab lwm yam)
NBR yog softer, EPDM yog me ntsis nyuaj thiab muaj ib tug txawv saj
1. Roj hmab cov ntsiab lus dav dav
(1) General roj hmab: xws li NR/BR/SBR/EPDM
(2) Cov roj hmab tshwj xeeb: xws li SR / FPM / CIIR / HNBR / CSM 2.
Nitrile roj hmab NBR muaj roj zoo, feem ntau hu ua roj-pov thawj roj hmab, thiab feem ntau yog siv los ua roj foob.
Ntuj roj hmab NR muaj elasticity zoo thiab zoo tag nrho kev ua tau zoo, tab sis tsis zoo txias tsis kam thiab alkali tsis kam.Feem ntau siv los ua cov log tsheb
Styrene Butadiene Roj Hmab SBR Cov roj hmab pheej yig tshaj plaws hauv ntiaj teb, siv los ua lub ncoo
EPDM muaj kev tiv thaiv corrosion zoo thiab rwb thaiv tsev zoo, thiab tuaj yeem siv los ua cov ntaub ntawv hnav-tiv taus lossis cov khoom siv hluav taws xob siab.
Neoprene CR muaj kev hnav zoo thiab tuaj yeem siv los ua lub cushion Chlorosulfonated polyethylene CSM muaj qhov ua tau zoo txias.
Tom ntej: Polytetrafluoroethylene PTFE
Yas huab tais, zoo heev acid thiab alkali tsis kam, tuaj yeem tiv taus hydrofluoric acid.Nws muaj ntau yam kev siv thiab tuaj yeem siv los ua cov kav dej rau cov kua corrosive.
Hebei CONQI VEHICLE FITTINGS Co., Ltd. yog ib lub tuam txhab mob siab rau tsim thiab faib cov roj hmab hose, EPDM hose, zaub mov qib hose thiab pvc hose thiab lwm yam nrog kev nplua nuj ntau lawm, kev tsim khoom siab heev thiab ua tiav thiab kev tswj xyuas zoo.Hauv xyoo 2009, lub tuam txhab ua tiav tag nrho cov khoom tsim tawm tus nqi ntawm 10.01 lab yuan thiab ua tiav cov se warehouse ntawm 250,000 yuan.Tag nrho cov ntawm lawv yog txuam nrog ntau tshaj 30 domestic OEMs xws li Jinlong, Yutong, Ankai, thiab Zhongtong, thiab nrog thoob ntiaj teb ceg ntawm Volvo thiab Is Nrias teb, New Zealand, Thaib, Taiwan, Poland, Ixayees, Britain, Egypt, Spain, Qaib ntxhw, Brazil, Singapore, Lub teb chaws Yelemees thiab ntau dua 20 lub teb chaws thiab cheeb tsam tau txais cov chaw txhawb nqa.Ua raws li lub ntsiab lus ntawm "kev txhim kho txuas ntxiv, kev ua tau zoo, zoo heev, thiab kev txaus siab rau cov neeg siv khoom", peb tau mob siab ntes cov cuab yeej technology thoob ntiaj teb tshiab thiab cov ntaub ntawv khoom, tas li tsim thiab tsim cov khoom tshiab, thiab muab cov neeg siv khoom.
