BG-2655-100

Wakiilka Daaweynta Biyaha-BG-2655-100

Sharaxaad Gaaban:

BG-2655-100 waa wakiilka daaweynta isocyanate biyo ah oo ku salaysan hexamethylene diisocyanate, loo isticmaalo in lagu daro polyurethane biyaha, polyacrylate, oo leh caabbinta hydrolysis heer sare ah iyo iska caabin kulaylka.

Dahaarka laba-qaybood ee biyo-ku-salaysan ee diyaarsan wuxuu leeyahay sifooyin dhalaalaya sare, buuxnaan sare, qallafsanaan sarreeya, caabbinta jaalaha ah ee aad u fiican, iyo caabbinta kiimikaad heer sare ah.

Tilmaamaha

Muuqashada	Dareere hufan oo cad ilaa waxoogaa huruud ah
Waxyaabo aan isbedelayn (%)	98-100
Viscosity (mPa • s/25 ℃)	1500-4500
HDI monomer bilaash ah (%)	≤0.5
Nuxurka NCO (sahayda%)	19.0-21.0

Tilmaamaha

Marka BG-2655-100 la kala firdhiyo, viscosity-kiisu wuu kordhi doonaa. Marka lagu daro kala firdhiyo polyol hydrophilic, waxaa lagu qasi karaa biyo ka hor ama qadar yar oo dareere ah ayaa lagu dari karaa si loo xakameeyo kororka viscosity, sida propylene glycol methyl ether acetate (PMA), propylene glycol diacetate (PGDA), iyo waxa waxaa lagu talinayaa in la isticmaalo dareerayaasha darajada polyurethane (waxyaabaha biyaha <0.05%) si loogu qaso, oo leh maaddo adag oo aan ka yarayn 40%. Samee tijaabooyin gaar ah iyo tijaabooyin xasilloonida kahor isticmaalka. Haddii isku darka ka dib marka lagu daro BG-2655-100, waa in lagu dhex isticmaalonolosha dheriga.

kaydinta

Alaabta waa in lagu kaydiyaa weel xiran si looga fogaado baraf iyo heerkul sare. Waxaa lagu talinayaa in lagu hayo baakadaha la xidhay oo ilaalinaya heerkulka kaydinta ee 5-35 ℃. Nolosha shelf ee alaabtu waa laba iyo toban bilood laga bilaabo taariikhda wax soo saarka. Ka dib markii nolosha shelf la dhaafo, waxaa lagu talinayaa in la sameeyo qiimeynta waxqabadka ka hor isticmaalka.

Alaabtu aad bay ugu nugul tahay qoyaanka waxayna la falgashaa biyaha si ay u soo saarto gaas sida kaarboon laba ogsaydh iyo urea, taas oo keeni karta cadaadiska weelka oo kor u kaca khatarna keena. Ka dib marka la furo xirmooyinka, waxaa lagu talinayaa in la isticmaalo sida ugu dhakhsaha badan.
