NBR waxay leedahay iska caabin saliid oo wanaagsan, EPDM waxay ku liidataa iska caabbinta saliidda mana aha mid waara, laakiin waxay iska caabin kartaa gabowga iyo kulaylka.Guud ahaan, EPDM waxaa inta badan loo isticmaalaa tuubooyinka biyaha iyo uumiga;EPDM waxay ku fiican tahay iska caabinta khilaaf.
1. Nitrile rubber NBR waa caag kaarboon ah oo aan saturated lahayn, kaas oo ka samaysan acrylonitrile iyo butadiene.Iyada oo ku xidhan waxa ku jira acrylonitrile laga bilaabo hooseeyo ilaa sare, caabbinta saliidda waa la xoojiyaa, laakiin caabbinta qabow waa la dhimay.
Iska caabbinta saliidda waa qaabka ugu weyn ee NBR nitrile caag ah, kaas oo leh iska caabin wanaagsan saliidaha ku salaysan batroolka iyo dareerayaasha aan dabaylaha ahayn, laakiin caabbinta liidata ee saliidaha polar iyo dareerayaasha polar.
1. Hanti antistatic wanaagsan;
2. Iska caabin liidata ozone;
3. Waxa ay si fiican ula jaanqaadi kartaa alaabta dabaysha, sida polyvinyl chloride (PVC), polyoxymethylene (POM), naylon, waxaana laga samayn karaa caag iyo caag.
4. Kala duwanaanshaha heerkulka hawlgalka ee caagga nitrile caadiga ah: -20°C ~ 120°C, iyo noocyada u adkaysta heerkulka hooseeya waxay ka hoosayn karaan -50°C;
2. Rabadhka Ethylene-propylene waxay u isticmaashaa ethylene iyo propylene sida alaabta ceeriinka ah, waxaana loo qaybin karaa binary ethylene-propylene rubber (EPM) iyo rubber ethylene-propylene (EPDM).
Astaamaha caagga ethylene propylene:
1. Ozone caabbinta gabowga
2. Cimilada iska caabinta
3. Iska caabinta kulaylka
Saddexda guri ee kore ayaa ah kuwa ugu wanaagsan caag guud.Waxa kale oo jira guryahan soo socda
4. Biyo caabbinta heer sare ah, iska caabbinta kulaylka sare iyo caabbinta uumiga biyaha;
5. Iska caabin kiimiko oo heer sare ah;
(Sababtoo ah xasiloonida kiimikada iyo caag la'aanta ethylene-propylene lafteeda, kiimik ahaan kama falceliso kiimikooyinka intooda badan, waa mid aan ku habboonayn ama wax yar ayay la jaanqaadi kartaa walxaha polar, waxayna u adkaysataa khamriga, acid, alkali xooggan, oxidizing. wakiilada, wakiilada dhaqida, saliidaha xoolaha iyo khudradda, ketones, iwm.)
NBR way jilicsan tahay, EPDM xoogaa way adag tahay waxayna leedahay dhadhamin ka duwan
1. Qodobbada guud ee caagga ah
(1) Caag guud: sida NR/BR/SBR/EPDM
(2) caag gaar ah: sida SR/FPM/CIIR/HNBR/CSM 2.
Rabadhka Nitrile NBR wuxuu leeyahay iska caabin saliideed oo wanaagsan, oo badanaa loo yaqaan caag aan saliid lahayn, waxaana badanaa loo isticmaalaa shaabad saliid ah.
NR caag dabiici ah ayaa leh dabacsanaan wanaagsan iyo waxqabadka guud ee wanaagsan, laakiin iska caabin qabow oo liita iyo iska caabin alkali ah.Inta badan loo isticmaalo sida taayirada baabuurta
Styrene Butadiene Rubber SBR Kaanka ugu jaban aduunka, loo isticmaalo suuf ahaan
EPDM waxay leedahay iska caabin daxalka oo wanaagsan iyo dahaar wanaagsan, waxaana loo isticmaali karaa sidii qalab u adkaysta ama qalabka korantada sare
Neoprene CR waxay leedahay caabbinta xirashada wanaagsan waxaana loo isticmaali karaa sidii barkin Chlorosulfonated polyetylen CSM waxay leedahay iska caabin qabow oo wanaagsan
Polytetrafluoroethylene PTFE
Boqorka caaga ah, acid aad u fiican iyo caabbinta alkali, waxay u adkeysan kartaa hydrofluoric acid.Waxa ay leedahay adeegsiyo kala duwan waxaana loo isticmaali karaa sidii dhuumaha dareeraha wasakhaysan.
Hebei CONQI VEHICLE FITTINGS Co., Ltd waa shirkad u heellan inay soo saarto oo qaybiso tuubada caagga ah ee baabuurta, tuubada EPDM, tuubada heerka cuntada iyo tuubada pvc iwm oo leh khibrad wax soo saar qani ah, tignoolajiyada wax soo saarka sare leh iyo nidaamka maaraynta tayada dhamaystiran iyo sayniska.Sannadkii 2009, shirkaddu waxay dhamaystirtay wadarta qiimaha wax soo saarka warshadaha oo dhan 10.01 milyan yuan waxayna dhamaystirtay cashuur bakhaar oo dhan 250,000 yuan.Dhammaantood waxay ku habboon yihiin in ka badan 30 OEM-yada gudaha ah sida Jinlong, Yutong, Ankai, iyo Zhongtong, iyo laamo caalami ah oo Volvo iyo India, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Masar, Spain, Turkey, Brazil, Singapore, Germany iyo in ka badan 20 waddan iyo gobollo ayaa helay tas-hiilaad taageero ah.U hoggaansanaanta mabda'a "horumar joogto ah, heer sare, tayo aad u wanaagsan, iyo qanacsanaanta macaamiisha", waxaan si taxadar leh u qabsanaa tignoolajiyada caalamiga ah ee ugu dambeeyay iyo macluumaadka badeecada, si joogto ah u naqshadeyna oo u horumarinayna alaabooyin cusub, waxaana siinaa macaamiisha.
