Tuubbo Bir ah oo Polyurethane ah oo la dahaadhay

Tuubada birta ah ee Polyurethane-ka lagu dahaadhay waa badeeco tuubooyin ah oo u adkaysta xirashada badan, taas 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 hadhuudhka. Astaamaha 1. U adkaysta xirashada 2. Ka hortagga Cabbirka 3. U adkaysta daxalka 4. U adkaysta gabowga hydrolysis 5. Dabacsanaan Sare 6. U adkaysta Shoogga Farsamada 7. Is-saliidaynta Arex waxay doorataa prem...
