1. Cufnaanta hoose iyo buuxinta sare
Cufnaanta caagga ethylene propylene waa nooc ka mid ah caag hoose, cufnaantiisuna waa 0.87.Intaa waxaa dheer, saliid aad u badan ayaa lagu buuxin karaa oo lagu dari karaa, sidaas darteed qiimaha alaabooyinka caagga ah waa la dhimi karaa, iyo khasaaraha qiimaha sare ee ethylene-propylene caag cayriin ah ayaa la samayn karaa.Wixii caag ethylene-propylene leh oo leh qiime sare oo Mooney ah, tamarta jireed iyo farsamada waa la dhimi karaa ka dib marka la buuxiyo sare.aan weynayn.
2. Iska caabinta gabowga
Rabadhka Ethylene-propylene wuxuu leeyahay iska caabin cimilo oo heer sare ah, caabbinta ozone, caabbinta kulaylka, caabbinta aashitada iyo alkali, caabbinta uumiga biyaha, xasilloonida midabka, guryaha korantada, buuxinta saliidda iyo dareeraha heerkulka qolka.Alaabooyinka caagga ah ee Ethylene-propylene waxaa la isticmaali karaa waqti dheer 120 ° C, waxaana loo isticmaali karaa si ku meel gaar ah ama si joogto ah 150-200 ° C.Ku darida wakiilka ku haboon ee gabowga ayaa kordhin kara heerkulka adeegiisa.EPDM caag iskutallaab ah oo leh peroxide waxaa loo isticmaali karaa xaalado adag.Marka la eego shuruudaha fiirsashada ozone ee 50pphm iyo fidinta 30%, caag EPDM wuxuu gaari karaa in ka badan 150h iyada oo aan dillaacin.
3. Iska caabinta daxalka
Sababtoo ah la'aanta polarity iyo heerka hoose ee unsaturation ee caagga ethylene-propylene, waxay leedahay iska caabin wanaagsan oo ka mid ah kiimikooyinka kala duwan ee polar sida khamriga, acids, alkalis, oxidants, qaboojiyaha, saabuunta, saliidaha xayawaanka iyo khudradda, ketones iyo dufanka, iwm. ;Laakiin dareerayaasha aliphatic iyo caraf udgoon (sida shidaalka, benzene, iwm) iyo xasilloonida liidata ee saliidda macdanta.Waxqabadku wuxuu sidoo kale hoos u dhigi doonaa waxqabadka muddada-dheer ee aashitada xoogga leh.
4. U adkaysiga uumiga biyaha
Rabadhka Ethylene-propylene wuxuu leeyahay iska caabbinta uumiga biyaha oo aad u wanaagsan waxaana lagu qiyaasaa inuu ka sarreeyo iska caabbinta kulaylka.Uumiga kulul ee 230°C, ma jiro wax isbedel ah oo muuqaal ah kadib ku dhawaad 100 saacadood.Isla shuruudo isku mid ah, caag silikoon ah, caag fluorosilicone, caag butyl ah, caag nitrile ah, iyo caag dabiici ah ayaa la kulmi doona muuqaal ahaan sii xumaanaya muddo gaaban ka dib.
5. Iska caabbinta biyaha kulul
Rabadhka Ethylene-propylene waxa kale oo uu leeyahay iska caabin ka wanaagsan biyaha kulul, laakiin waxa ay si dhow ula xidhiidhaa dhammaan hababka vulcanization.Rabadhka ethylene-propylene oo leh dimorpholine disulfide iyo TMTD sida nidaamka vulcanization ayaa wax yar ka beddelaya sifooyinka farsamada ka dib markii lagu qooyay biyo kulul 125 ° C muddo 15 bilood ah, iyo heerka fidinta mugga waa 0.3% oo keliya.
6. Guryaha korantada
Rabadhka Ethylene-propylene wuxuu leeyahay sifooyin koronto oo heer sare ah iyo iska caabin koronto ah, sifooyinkiisa korantada ayaa ka sarreeya ama ku dhow kuwa caagga styrene-butadiene, polyetylen chlorosulfonated, polyetylen iyo polyetylen iskutallaabta.
7. Elasticity
Maaddaama aysan jirin wax beddelaad ah oo ku jira qaab-dhismeedka molecular ee caagga ethylene-propylene, tamarta isku-dhafka ah ee molecule waa mid hooseeya, silsiladda molecular waxay ilaalin kartaa dabacsanaanta ballaaran, oo keliya marka loo eego caagga dabiiciga ah iyo caagga butadiene, oo wali sii wadi kara. heerkulka hooseeya.
8. Dheefsiga
Sababtoo ah la'aanta kooxaha firfircoon ee qaab dhismeedka molecular ee caagga ethylene-propylene, tamarta isku xiran ayaa hooseysa, caagguna waa sahlan tahay in uu ubaxo, is-ku-dhejinta iyo isku-duubnida wadajirka ah ayaa aad u liita.
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.
