SWD noo noo kho urethane ntawm txuas hniav

piav qhia luv luv:

SWD ya raws kho polyurethane muaj anticorrosion tiv thaiv txheej siv ib feem ntawm polyurethane resin polymer ua raw khoom.Cov zaj duab xis daim nyias nyias yog ntom, compact thiab elastic, nws muaj peev xwm hloov mus rau me ntsis deformation yam tsis muaj kab nrib pleb los ntawm kev co thiab huab cua hloov nyob rau hauv ntau yam hlau qauv ntawm industrial lag luam.Nws zam kev nkag mus ntawm huab cua, noo noo thiab lwm yam corrosion media los tiv thaiv xeb ntawm cov qauv hlau.Cov zaj duab xis txheej muaj ntau ntawm urea daim ntawv cog lus, biuret daim ntawv cog lus, urethane daim ntawv cog lus thiab hydrogen daim ntawv cog lus kom ua tau zoo heev lub cev thiab kev ua haujlwm tiv thaiv corrosion.
