SWD9594 mwando kurapa polyurethane makemikari ekuchengetedza matangi emukati madziro anorema basa anticorrosion coating
Tangi yekuchengetera kemikari chinhu chakakosha mufekitori yemakemikari, kana matangi adonha kana kukuvara, hazvizokonzerese kurasikirwa nemidziyo asiwo zvinokuvadza vashandi.SWD9594 ibasa repamusoro chimwe chikamu chehunyoro chinorapa polyurethane coating material, iyo yekuputira inotora yakawanda urea bond, maviri urea bond, urethane bond uye hydrogen bond panguva ye pre polymerization process, inorapwa mushure mekunyura nehunyoro hwemhepo, iyo dense cross- yakabatana interpenetrating network inoita kuti firimu rekuputira rive rakasimba makemikari kuramba uye pfuma yemuviri.Iyo ine yakanakisa kupinda mukati uye permeability maitiro, uye ichaita neiyo hydroxyl bond ye substrate kuitira kuti simba rekunamatira rivandudzwe zvakanyanya nemakemikari uye kunamatira kwemuviri.Mune matangi ekuchengetera emukati madziro application, SWD9594 coating inogona kuiswa inoenderana neyakakosha primer, inogona zvakare kushandiswa seyepasi yekubatanidza zvinhu.

SWD959 mwando kurapa polyurethane indasitiri anticorrosion inodzivirira coating
SWD959 mwando kurapa polyurethane indasitiri anticorrosion inodzivirira 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.
