Polyurethane (jaakad, sealants, adheses)
2% ~ 5% ee godka molikalive (budada) ee nidaamka ayaa ku filan in meesha laga saaro qoyaanka haraaga ah ee nidaamka PUT, laakiin ugu dambeyntii waxay kuxirantahay qoyaanka nidaamka.
Daaha ka hortagga
In the epoxy zinc-rich primer, a trace amount of water will produce a great reaction with the zinc powder, produce hydrogen, increase the pressure in the barrel, shorten the service life of the primer, resulting in the tightness, wear resistance and hardness of the coating film. Molecular sieve (powder) as a water absorption desiccant, which is totally physical adsorption, will eliminating water and without any react with the substrate. Marka xinjirowga molialical waa amaan oo ku habboon nidaamka ka hortagga daboolka.
Daboolida budada birta
Fal-celinta la midka ah waxay ku dhici kartaa jaakadaha birta ah ee birta ah, sida jaakadaha budada ah ee aluminium.
