NBR ine mafuta akanaka ekupikisa, EPDM yakashata mukudzivisa mafuta uye haisi yakasimba, asi inogona kudzivisa kukwegura uye kupisa.Kazhinji, EPDM inonyanya kushandiswa kune pombi dzemvura uye pamusoro pemhepo;EPDM iri nani mukupokana.
1. Nitrile rubber NBR is polar unsaturated carbon chain rubber, iyo inogadzirwa kubva kune acrylonitrile uye butadiene.Zvichienderana nezviri mukati me acrylonitrile kubva pasi kusvika kumusoro, kupikisa kwemafuta kunowedzerwa, asi kutonhora kunoderera.
Kuramba kwemafuta ndicho chinhu chikuru cheNBR nitrile rabha, ine kumira zvakanaka kumafuta epetroleum-based uye non-polar solvents, asi kushomeka kupikisa mafuta epolar uye polar solvents.
1. Yakanaka antistatic pfuma;
2. Kusagadzikana kwe ozone;
3. Iine kuwirirana kwakanaka nezvinhu zvepolar, zvakadai se polyvinyl chloride (PVC), polyoxymethylene (POM), nylon, uye inogona kugadzirwa murubha uye plastiki zvinhu.
4. Tembiricha yekushanda yeyakajairika nitrile rabha: -20°C ~ 120°C, uye yakaderera tembiricha siyana marudzi anogona kuderera kupfuura -50°C;
2. Ethylene-propylene rubber inoshandisa ethylene uye propylene seyakagadzirwa zvigadzirwa, uye inogona kugoverwa mubhinari ethylene-propylene rubber (EPM) uye tertiary ethylene-propylene rubber (EPDM).
Zvimiro zve ethylene propylene rubber:
1. Ozone kuchembera kuramba
2. Kuramba kwemamiriro ekunze
3. Kudzivisa kupisa
Zvinhu zvitatu zviri pamusoro apa ndizvo zvakanakisa murabha.Panewo zvinhu zvinotevera
4. Yakanakisa kudzivirira kwemvura, kupisa kwakanyanya uye kusagadzikana kwemhute yemvura;
5. Yakanakisa makemikari kuramba;
(Nekuda kwekugadzikana kwemakemikari uye kwete-polarity ye ethylene-propylene rubber pachayo, haina makemikari inopindirana nemakemikari akawanda, haipindirani kana kuti haina kuwirirana zvishoma nezvinhu zvepolar, uye inopikisa doro, asidi, alkali yakasimba, oxidizing. vamiririri, washing agents, mhuka nemafuta emiriwo, ketoni, nezvimwewo)
NBR yakapfava, EPDM yakaoma zvishoma uye ine kuravira kwakasiyana
1. Rubber general points
(1) General rubber: yakadai seNR/BR/SBR/EPDM
(2) Special rabha: senge SR/FPM/CIIR/HNBR/CSM 2.
Nitrile rabha NBR ine yakanaka mafuta kuramba, inowanzozivikanwa semafuta-proof rabha, uye inowanzoshandiswa sechisimbiso chemafuta.
Natural rabha NR ine elasticity yakanaka uye yakanaka kuita kwese, asi kushomeka kutonhora uye alkali kuramba.Kazhinji inoshandiswa semavhiri emotokari
Styrene Butadiene Rubber SBR Rabha yakachipa pasi rose, inoshandiswa sepadhi
EPDM ine yakanaka corrosion resistance uye yakanaka kuvharira, uye inogona kushandiswa sezvipfeko zvinodzivirira kupfeka kana high-voltage magetsi zvinhu.
Neoprene CR ine yakanaka kupfeka kuramba uye inogona kushandiswa secushion Chlorosulfonated polyethylene CSM ine yakanaka kutonhora kupikisa.
Polytetrafluoroethylene PTFE
Plastic king, yakanakisa asidhi uye alkali kuramba, inogona kumira hydrofluoric acid.Iine huwandu hwakawanda hwekushandisa uye inogona kushandiswa sepombi yezvinwiwa zvinoparadza.
Hebei CONQI VEHICLE FITTINGS Co., Ltd. ikambani yakatsaurirwa kugadzira uye kugovera auto rabha hose, EPDM hose, chikafu chegiredhi hose uye pvc hose nezvimwe zvine ruzivo rwakapfuma rwekugadzira, tekinoroji yekugadzira yepamusoro uye yakakwana uye yesainzi yemhando yekutarisira hurongwa.Muna 2009, kambani yakapedzisa kukosha kwehuwandu hwemaindasitiri e10.01 miriyoni yuan uye yakapedzisa mutero wekuchengetedza 250, 000 yuan.Ese anofananidzwa neanopfuura makumi matatu epamba maOEM akadai seJinlong, Yutong, Ankai, uye Zhongtong, uye nemapazi epasi rose eVolvo neIndia, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Egypt, Spain, Turkey, Brazil, Singapore, Germany uye nyika dzinopfuura makumi maviri nematunhu vakawana zvivakwa zvekutsigira.Tichiomerera kune dzidziso ye "kuenderera mberi kwekuvandudza, kunaka, kunaka kwakanakisa, uye kugutsikana kwevatengi", isu tinotora zvine hunyanzvi tekinoroji yepasirese uye ruzivo rwechigadzirwa, tichigara tichigadzira nekugadzira zvigadzirwa zvitsva, nekupa vatengi.
