Saliida xoolaha iyo khudradda ee habboon Neoprene (CR) Balanbaalista Valve Kursiga
Neoprene (CR)
Neoprene, Polychloroprene waxay ka kooban tahay chloroprene monomer polymerization. vulcanization ka dib, waxay leedahay barti wanaagsan caag iyo caabbinta naax. Waa anti-goglan waxayna leedahay iska caabin cimilo oo wanaagsan, adkaysi u leh qallooca rabshadaha, qaboojiyaha, acid dilute, saliidda ester silicon, laakiin aan u adkaysan karin taxanaha fosfate ee saliidda biyaha. Way fududahay in la miirto oo la adkeeyo heerkulka hooseeya, xasilloonida kaydinta daciifka ah, iyo ballaarinta weyn ee barta aniline ee hoose ee saliidda macdanta. Isticmaalka kala duwanaanta heerkulka waa - 50 ~ 150 darajo.
Faa'iidooyinka

Loo sameeyay si ay u bixiso wax qabad aan la barbar dhigi karin, weelkayaga balabaalista waxaa loo habeeyay inuu si cillad la'aan ah ugu shaqeeyo heerkul ballaaran oo u dhexeeya -50 ilaa +150 darajo Celsius. Tani waxay ka dhigaysaa doorashada ugu habboon ee noocyo badan oo codsiyo ah, laga bilaabo tas-hiilaadka biyaha lagu daweeyo ilaa warshadaynta cuntada iyo cabitaanka, halkaasoo ilaalinta nadaafadda iyo ka hortagga faddaraynta ay muhiim tahay. Midabka madow ee xargaha ma aha oo kaliya qurxinta; waxa ay tilmaamaysaa wax soo saarka loogu talagalay in ay u adkeyso caqabadaha kala duwan ee jawi adag, hubinta cimri dherer iyo isku halaynta.Waxa dejinaya fayadhowrkayaga EPDM+PTFE isku darka balasalka balastar-kaafiyaha marka laga reebo waa ku habboonaanta warbaahinta kala duwan, oo ay ku jiraan biyaha, biyaha la cabbi karo, biyaha la cabbo, iyo biyaha wasakhda ah. La jaanqaadka dareeraha tirada badan ee noocaas ah waxay marag u tahay injineernimada fikirka leh iyo tayada sare leh ee loo isticmaalo soo saaristiisa. Haddii aad ku jirto ganacsiga maaraynta adeegyada biyaha, hubinta badbaadada biyaha la cabbo, ama la tacaalida hababka xasaasiga ah ee warshadaha cuntada iyo cabitaanka, kursigeena balaalista balaastikada ayaa loo habeeyey si uu u daboolo baahiyahaaga. Balaastigga Sansheng Fluorine, waxaad dooranaysaa lammaane u go'ay heer sare, hal-abuurnimo, iyo heerarka ugu sarreeya ee qanacsanaanta macaamilka.
