    Alaabooyinka & Tilmaamaha

    RFE polyisocyanate waa iskutallaab aad waxtar u leh oo loogu talagalay dhejisyada ku salaysan polyurethane, caag dabiici ah iyo caag Synthesis ah. RFE polyisocyanate sidoo kale waxay faa'iido u leedahay hagaajinta ku dhejinta walxaha ku salaysan caag. Waxaa loo isticmaali karaa sidii crosslinker halkii laga isticmaali lahaa Bayer's Desmodur RFE.

    Isticmaalka

    Xabagta laba qaybood ka kooban waa in la isticmaalo muddada lagu dabaqi karo ka dib marka la geliyo RFE.
    Dhererka muddada lagu dabaqi karo kaliya maaha mid la xidhiidha maadada polymer ee koollada, laakiin sidoo kale qaybaha kale ee khuseeya (sida resin, Antioxygen, plasticizer, dareeraha, iwm.
    Marka ay ku dhowdahay xilliga lagu dabaqi karo, badiyaa dhowr saacadood ama hal maalin oo shaqo ah, koollada ayaa aad u adkaan doonta in la shaqeeyo, iyo viscosity-ku dhaqso ayuu u kacaa.
    Ugu dambeyntii, waxay noqotaa jelly aan la beddeli karin. 100 xabag tayo leh, Hydroxyl polyurethane (Polyurethane xisaabteeda qiyaastii 20%), RFE waxay samaysaa 4-7. Chloroprene caag ah (Koontada caagga ah qiyaastii 20%), RFE waxay samaysaa 4-7.

    Baakaynta iyo Kaydinta

    Xidhmada: 0.75kg/dhalo, wadar ahaan 20 dhalo oo ku jira hal kartoon, 180kg/fuusto, AMA sida ay macaamiishu codsadaan.
    Fadlan ku kaydi weelka asalka ah ee la shaabadeeyey ee ka hooseeya 23 ℃, alaabada waxaa lagu ilaalin karaa xasilloon muddo lix bilood ah.
    Dhammaan alaabooyinka taxanaha Crosslinker aad bay ugu nugul yihiin qoyaanka; waxay soo saari doontaa kaarboon laba ogsaydh iyo urea aan milmi karin marka ay falcelinta biyaha la timaado.
    Haddii soo-gaadhista hawada ama iftiinka, waxay dedejin doontaa isbeddellada midabka ee alaabta, Laakiin shaqada la taaban karo ma saameyn doonto.
