Makristaro machena kana upfu hwekristaro machena, hunonyungudika mumvura, doro uye zvimwe zvinonyungudutsa zvakasikwa. Mvura yacho ine acidic
1,2,3,4-Butanetetracarboxylic acid (BTCA) imushonga wekupedzisa usina formaldehyde (DP). Ine simba guru rekuita uye haina hwema hunotsamwisa. Machira akadai sedonje nesirika anogona kushandiswa neBTCA, kusanganisira kudzivirira kupera, kudzvanya zvachose uye kuchengetedza chimiro chayo uye anogara kwenguva refu.
BTCA inogona kushandiswa kugadzira zvinhu zvepolyimide. Rudzi urwu rwezvinhu rune simba guru rekudzivirira kupisa, rekudzivirira acid, rekudzivirira hydrocarbon uye hunhu hwakanaka hwekudzivirira magetsi, uye inogona kushandiswa kugadzira zvinhu zvakasiyana-siyana zvepolymer zvinoshanda, zvakaita sezvinhu zvinonzwa chiedza, zvinhu zvepolymer zvekurapa uye zvinhu zvinoshanda zvepolymer membrane. Inogona kushandiswa kugadzira mhete dzekudzivirira magetsi, waya dzekuputira uye zvinhu zvinodzivirira magetsi.
Bhegi repepa rine macomposite re25kg rePolish - rineni kana sezvinodiwa nemutengi.
Kuchengetera:
Chengeta munzvimbo ine mumvuri uye ine mhepo inofefetera. Nguva yayo yekushanda kwemwedzi gumi nemiviri. Inogona kushandiswa kana yapera.
Kutakura:
Dzivisa kupisa kwakanyanya uye kupiswa nezuva panguva yekufambisa.
