Filimka kulul ee dhalaalka ah miyuu ka kooban yahay walxaha waxyeellada leh sida formaldehyde?
Qaybaha ugu muhiimsan ee filimka kulul ee dhalaalka kulul ayaa ah polymers molecular sare, taas oo ah, polyamide, polyurethane iyo qalab kale.
Waxay leeyihiin heerar sare oo polymerization ah, sidaas darteed maaha kuwo waxyeello u leh jidhka bini'aadamka. Isla mar ahaantaana, filimka koollada kuleylka leh ayaa qoyan
dusha sare ee walxaha ku dheggan kuleylinta iyo dhalaalidda, oo uma baahna dareere si ay u caawiyaan qoyan walxaha.
Sidaa darteed, filimka kulul ee koollada kulul waa koollo deegaanka u wanaagsan oo aan ku jirin formaldehyde ama dareerayaasha.
