Qiimaha ugu fiican Desmodur RE / Isocyanate RE ee xabagta CAS 2422-91-5
Our RE waa wakiilka iskutallaabta ah oo aad u firfircoon, Loo isticmaalo xabagta ay sameeyeen hydroxyl polyurethane, caag dabiici ah ama synthetic, waxay leedahay xoog isku xirnaanta heer sare ah oo caag ah iyo kaab loo isticmaalo xabagta, antioxidant, wakiilka balaastikada, cadaadiska-xasaasi ah iwm. waxaa loo isticmaali karaa sidii crosslinker halkii laga isticmaali lahaa BAYER's Desmodur RE.
Faahfaahinta alaabta:
Magaca Kiimikada: Triphenylmethane-4,4',4''-triisocyanate
Qaacidada molecular: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
Dabeecada: saaraha
Qaab dhismeedka: HC[ NCO]3
Cufnaanta: 1.0g/c m3, 20℃

RE, oo sidoo kale loo yaqaan TTI, waa xal ka kooban 27.5% triphenylmethane-4,4ˊ,4,-triisocyanate iyo 72.5% ethyl acetate. Waa wakiilka daawaynta caalamiga ah/crosslinker ee koollada ku salaysan hydroxyl polyurethane, caag dabiici ah iyo synthetic, gaar ahaan u fiican isku xidhka alaabta caag ah. Waxa kale oo aad loo isticmaalaa in lagu xidho biraha caag ah. Intaa waxaa dheer, RE waxaa lagu dabaqi karaa resin, antioxidant, plasticizer, iwm. Goobta koollada, RE waxaa lagu dabaqaa sida wakiilka isku-dhafka ah ee koollada neoprene iyo / ama p hydroxyl polyurethane koollada meelaha kabaha. Guud ahaan, si loo daweeyo xabagta 100 qaybood oo miisaan ahaan ah (pbw) oo ku salaysan qiyaasta lagu taliyey ee 4-7 pbw RE. Nolosha dheriga ee xabagta isku qasan waa ku dhawaad saacado.
Xabagta laba qaybood ka kooban waa in la isticmaalaa gudaha muddada lagu dabaqi karo ka dib marka la geliyo RE. Dhererka muddada lagu dabaqi karo ma aha oo kaliya la xidhiidha maadada polymer ee xabagta, laakiin sidoo kale qaybaha kale ee khuseeya (sida resin, antioxygen, plasticizer, dareeraha, iwm. Marka ay ku dhowdahay muddada lagu dabaqi karo, badanaa dhowr saacadood ama hal maalin shaqo, koolo Waxay noqotaa mid aad u adag in la shaqeeyo, iyo viscosity ayaa kor u kaca ugu dhakhsaha badan, Waxay noqotaa 100 xabagta tayada leh, Hydroxyl polyurethane (akoonka polyurethane ee qiyaastii 20%), RE dose 4-7 chloroprene. , RE wuxuu sameeyaa 4-7.
Baakad:
750g/dhalo, 20 dhalo oo hal kartoon ku jira, 24 ama 30 kartoon oo hal baalad ah;
20kg/durbaan, 18 durbaan ama 27 durbaan oo hal palette ah;
55kg/durbaan, 8 ama 12 durbaan oo hal palette ah;
180kg / durbaan, 4 durbaan oo ku jira hal baaldi
Kaydinta:
Fadlan ku kaydi weelka asalka ah ee la shaabadeeyey ee ka hooseeya 23 ℃, alaabada waxaa lagu ilaalin karaa degganaansho 12 bilood ah. Waxay aad u xasaasi u tahay inta badan; waxay soo saari doontaa kaarboon laba ogsaydh iyo urea aan milmi karin marka ay fal-celinta biyaha. Haddii soo-gaadhista hawada teh ama iftiinka, waxay dedejin doontaa isbeddelada midabka, laakiin shaqada la taaban karo ma saameyn doonto.
