Dhuumaha birta ee dahaaran ee polyurethane
Tuubooyin bir ah oo dahaaran oo polyurethane ah ayaa ah alaab tayo sare leh oo u adkeysata dhuumaha, taas oo si weyn loogu isticmaalo dhuumaha farsamaynta macdanta iyo dhuumaha gudbinta dabada.Saldhigga tamarta fosil-shidaalka waxay u isticmaashaa dhuumaha dhuxusha iyo hababka dambaska looga saaro, iyo sidoo kale saliidda, kiimikada, sibidhka iyo warshadaha badarka.
Astaamaha
1. Xiro u adkaysta
2.Ka Hortagga Cabitaannada
3. Iska caabinta daxalka
4. U adkaysiga gabowga hydrolysis
5. Balaasti sare
6. Iska caabinta Shock Makaanikada
7. Is-saliid
Arex waxay doorataa dufcada sare ee premium oo leh hab nano-la beddelay si loo xoojiyo shaqada maaddada poliurethane.Waxay ka dhigtaa alaabada xayndaabka leh ee polyurethane qaab-dhismeedka kiimikaad ee joogtada ah waxayna muujisaa la qabsigeeda xaalada shaqada.
Dhuumaha birta ee poliurethane, sida mid ka mid ah patent-ka gudaha ee alaabta macdanta ee Arex, waa caan oo ay isticmaalaan macaamiisheena macdanta.
