Qiimaha ugu fiican Desmodur RE ee dhejisyada CAS 2422-91-5 Triphenylmethane -4,4`,4“-triisocyanate/ Methylidintri-p-phenylene triisocyanate
RE-geenu waa wakiil isku xidha isku xidhka aadka u firfircoon, Waxaa loo isticmaalaa dhejisyada ay sameeyeen hydroxyl polyurethane, caag dabiici ah ama macmal ah, waxay leedahay awood isku xidhnaan oo aad u fiican oo ku jirta cinjirka waxaana loo isticmaali karaa resin, antioxidant, plasticizing walax, iyo cadaadis xasaasi ah iwm. Waxaa loo isticmaali karaa isku xidhka isku xidhka halkii laga isticmaali lahaa BAYER's Desmodur RE.
Faahfaahinta alaabta:

RE-geena, oo sidoo kale loo yaqaan TTI, waa xal ka kooban 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate iyo 72.5% ethyl acetate. Waa wakiil daaweyn/iskutallaab caalami ah oo loogu talagalay dhejiska ku salaysan hydroxyl polyurethane, caagagga dabiiciga ah iyo kuwa macmal ah, gaar ahaan aad ugu fiican isku xidhka walxaha caagga ah. Waxa kale oo si weyn loogu isticmaalaa isku xidhka biraha leh caagga. Intaa waxaa dheer, RE waxaa lagu dabaqi karaa resin, antioxidant, plasticizer, iwm. Goobta dhejiska, RE waxaa loo isticmaalaa sidii wakiilka isku xidhka dhejiska neoprene iyo/ama p hydroxyl polyurethane ee meelaha kabaha. Guud ahaan, si loo daaweeyo dhejiska 100 qaybood miisaan ahaan (pbw) iyadoo lagu saleynayo qaddarka lagu taliyay ee 4-7 pbw RE. Nolosha dheriga ee dhejiska isku dhafan waa qiyaastii saacado.
Koolada laba-qaybood leh waa in la isticmaalaa muddada ku habboon ka dib marka la geliyo RE. Muddada ku habboon ma aha oo kaliya inay la xiriirto waxa ku jira polymer-ka ee koolada, laakiin sidoo kale qaybaha kale ee khuseeya (sida resin, antioxygen, plasticizer, dareeraha, iwm. Marka ay ku dhowdahay muddada ku habboon, badanaa dhowr saacadood ama hal maalin oo shaqo ah, koolada way adkaanaysaa in la shaqeeyo, dheellitirkana wuu kordhaa dhawaan. Ugu dambeyntii, waxay noqotaa jelly aan la celin karin. 100 koolada tayo leh, Hydroxyl polyurethane (Polyurethane waxay ku xisaabtantaa qiyaastii 20%), qiyaasta RE 4-7. Cinjirka Chloroprene (Caydhka waxay ku xisaabtantaa qiyaastii 20%), RE-gayaga wuxuu sameeyaa 4-7.
Baakad:
750g/dhalo, 20 dhalo oo hal kartoon ku jira, 24 ama 30 kartoon oo hal baakad ku jira;
20kg/durbaan, 18 fuusto ama 27 fuusto oo hal baaldi ku jira;
55kg/durbaan, 8 ama 12 fuusto oo hal baaldi ku jira;
180kg/durbaan, 4 fuusto oo hal baaldi ku jira
Kaydinta:
Fadlan ku kaydi weelka asalka ah ee la shaabadeeyey heerkul ka hooseeya 23℃, badeecadaha waxaa lagu hayn karaa mid deggan 12 bilood. Aad bay u xasaasi u yihiin wasakhda; waxay soo saari doontaa kaarboon laba ogsaydh iyo urea aan milmi karin falcelinta biyaha. Haddii ay soo gaarto hawada ama iftiinka, waxay dedejin doontaa isbeddellada midabka, laakiin shaqada dhabta ah saameyn kuma yeelan doonto.
