NBR ili ndi kukana bwino kwa mafuta, EPDM ndi yosauka mu kukana mafuta komanso osakhazikika, koma imatha kukana ukalamba ndi kutentha.Nthawi zambiri, EPDM imagwiritsidwa ntchito kwambiri pamapaipi amadzi komanso pamwamba pa nthunzi;EPDM ndiyabwino pakukana kukangana.
1. Nitrile rabara NBR ndi polar unsaturated carbon chain rabara, amene copolymerized kuchokera acrylonitrile ndi butadiene.Malingana ndi zomwe zili mu acrylonitrile kuchokera kumunsi kupita kumtunda, kukana kwa mafuta kumawonjezeka, koma kuzizira kumachepetsedwa.
Kukana kwamafuta ndi gawo lalikulu kwambiri la rabara ya NBR nitrile, yomwe imalimbana bwino ndi mafuta opangidwa ndi petroleum ndi zosungunulira zopanda polar, koma kukana kwamafuta aku polar ndi zosungunulira za polar.
1. Katundu wabwino wa antistatic;
2. Kusamvana kwa ozoni;
3. Zimagwirizana bwino ndi zipangizo za polar, monga polyvinyl chloride (PVC), polyoxymethylene (POM), nayiloni, ndipo zimatha kupangidwa kukhala mphira ndi pulasitiki.
4. Kutentha kwa ntchito kwa mphira wamba wa nitrile: -20 ° C ~ 120 ° C, ndipo mitundu yotsika yolimbana ndi kutentha ikhoza kukhala yotsika kuposa -50 ° C;
2. Ethylene-propylene rabara amagwiritsa ntchito ethylene ndi propylene monga zopangira zopangira, ndipo akhoza kugawidwa mu mphira wa binary ethylene-propylene (EPM) ndi mphira wapamwamba wa ethylene-propylene (EPDM).
Makhalidwe a mphira wa ethylene propylene:
1. Kukana kukalamba kwa ozoni
2. Kukana kwanyengo
3. Kukana kutentha
Zomwe zili pamwambazi ndi zabwino kwambiri mu rabara.Palinso zinthu zotsatirazi
4. Kukana kwamadzi kwabwino, kukana kutentha kwambiri komanso kukana kwa nthunzi wamadzi;
5. Wabwino kukana mankhwala;
(Chifukwa cha kukhazikika kwa mankhwala komanso kusagwirizana ndi mphira wa ethylene-propylene palokha, sichimakhudzidwa ndi mankhwala ambiri, sichigwirizana kapena sichigwirizana kwambiri ndi zinthu za polar, ndipo sichigonjetsedwa ndi mowa, asidi, alkali wamphamvu, oxidizing. mankhwala, ochapira, nyama ndi masamba mafuta, ketoni, etc.)
NBR ndi yofewa, EPDM ndi yolimba pang'ono ndipo ili ndi kukoma kosiyana
1. Mfundo zazikuluzikulu za mphira
(1) Rubber General: monga NR/BR/SBR/EPDM
(2) Raba wapadera: monga SR/FPM/CIIR/HNBR/CSM 2.
Nitrile rabara NBR ili ndi kukana bwino kwamafuta, komwe kumadziwika kuti mphira wotsimikizira mafuta, ndipo nthawi zambiri imagwiritsidwa ntchito ngati chisindikizo chamafuta.
NR ya rabara yachilengedwe imakhala ndi kukhazikika bwino komanso magwiridwe antchito abwino, koma kuzizira kozizira komanso kukana kwa alkali.Nthawi zambiri amagwiritsidwa ntchito ngati matayala agalimoto
Mpira wa Styrene Butadiene SBR Wotsika mtengo kwambiri padziko lonse lapansi, womwe umagwiritsidwa ntchito ngati padi
EPDM ili ndi kukana bwino kwa dzimbiri komanso kutchinjiriza kwabwino, ndipo itha kugwiritsidwa ntchito ngati zida zosamva kuvala kapena zida zamagetsi zamagetsi
Neoprene CR ili ndi kukana kwabwino kovala ndipo imatha kugwiritsidwa ntchito ngati khushoni Chlorosulfonated polyethylene CSM imakhala ndi kukana kuzizira bwino.
Polytetrafluoroethylene PTFE
Mfumu ya pulasitiki, asidi wabwino kwambiri komanso kukana kwa alkali, imatha kupirira hydrofluoric acid.Ili ndi ntchito zambiri ndipo imatha kugwiritsidwa ntchito ngati payipi yamadzimadzi owononga.
Hebei CONQI VEHICLE FITTINGS Co., Ltd. ndi kampani yodzipereka kupanga ndi kugawa payipi ya rabara yamagalimoto, payipi ya EPDM, payipi ya chakudya ndi payipi ya pvc ndi zina zambiri zokhala ndi zopanga zambiri, ukadaulo wapamwamba wopanga komanso dongosolo lathunthu komanso lasayansi loyang'anira.Mu 2009, kampaniyo inamaliza mtengo wamtengo wapatali wa yuan 10.01 miliyoni ndikumaliza msonkho wanyumba yosungiramo katundu wa 250, 000 yuan.Onsewa amafanana ndi ma OEM opitilira 30 apakhomo monga Jinlong, Yutong, Ankai, ndi Zhongtong, komanso nthambi zamayiko a Volvo ndi India, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Egypt, Spain, Turkey, Brazil, Singapore, Germany ndi mayiko ndi madera oposa 20 apeza zothandizira.Potsatira mfundo za "kusintha kosalekeza, kuchita bwino kwambiri, khalidwe labwino kwambiri, ndi kukhutitsidwa ndi makasitomala", timagwira bwino ntchito zamakono zamakono ndi zamakono zapadziko lonse, timapanga nthawi zonse ndikupanga zatsopano, ndikupereka makasitomala.
