Tuubbo Bir ah oo Polyurethane ah oo la dahaadhay
Tuubooyinka birta ah ee Polyurethane-ka lagu dahaadhay waa badeeco dhuumaha ah oo aad u adkaysi badan, kaas oo si weyn loogu isticmaalo dhuumaha wax soo saarka macdanta iyo dhuumaha gudbinta dabada. Saldhigga korontada ee shidaalka fossil-ka wuxuu isticmaalaa dhuumaha nidaamyada ka saarista dhuxusha iyo dambaska, iyo sidoo kale warshadaha saliidda, kiimikada, sibidhka iyo badarka.
Astaamaha
1. Xiro u adkaysta
2. Ka hortag miisaanka
3. Iska caabinta Daxalka
4. Iska caabbinta gabowga hydrolysis-ka
5. Dabacsanaan Sare
6. Iska caabbinta Shoogga Farsamada
7. Is-saliidaynta
Arex waxay doorataa dufcadda ugu sarreysa iyadoo la adeegsanayo hab nano-modified ah si loo xoojiyo shaqada walxaha polyurethane. Waxay ka dhigtaa alaabada polyurethane ee la safeeyey qaab-dhismeed kiimiko oo deggan waxayna muujineysaa la qabsigeeda xaaladda shaqada.
Tuubada birta ah ee polyurethane-ka lagu dahaadhay, oo ah mid ka mid ah shatiyada gudaha ee wax soo saarka macdanta ee Arex, waa mid caan ah waxaana isticmaala macaamiisheenna macdan qodista.
