SWD mwando kurapa urethane pamabhiriji

tsananguro pfupi:

SWD mwando kurapa polyurethane maindasitiri anticorrosion anodzivirira coating inotora chimwe chikamu polyurethane resin polymer seyakagadzirwa zvinhu.Iyo firimu membrane ine dense, compact uye elastic, inogona kuchinjika kune kudiki deformation isina kuputika kubva kuvibration uye mamiriro ekunze kushanduka pane akasiyana simbi chimiro cheindasitiri yemaindasitiri.Iyo inodzivirira kupinda kwemhepo, hunyoro uye imwe corrosion media kuve anti rust yesimbi chimiro.Iyo firimu yekuputira ine yakawanda urea bond, biuret bond, urethane bond uye hydrogen bond kuti iite yakanakisa yemuviri zvivakwa uye anticorrosion kuita.
