Pu kuchengetedzwa shangu chete system
INtbroction
Pu yekuchengetedza shangu-yega system inoshandiswa kugadzira yekuchengetedza shangu kunze uye yemukati soles. Iyo ndiyo polyester-yakavakirwa ph system yezvinyorwa, ine zvikamu zvina, polyol, iso, hardner uye catalyst. Kugadziriswa kwehurongwa kune zviviri zvikamu. Iyo Catalyst, yakaoma, inovhuvhuta uye pigment inofanira kusanganisa zvakakwana neiyo Polyol Component Exd-320a, inosanganiswa neOsoxent Exd-3119B yekugadzira ekupedzisira ekupedzisira.
Zvivakwa zvemuviri
A, emukati masokisi ezvekuchengetedza shangu-yega yekugadzirira nzira:
