Qhov tseem ceeb rau qhov zoo ntawm kev siv tshuaj tsuag polyurea yuav muab faib ua hlau hlau thiab pob zeb substrates. Ntawm no yog yuav ua li cas nrog polyurea tshuaj tsuag substrates.
1. Kev kho cov tshuaj substrate: Tshuaj tua blasting ntawm cov pob zeb precast los yog tshem tawm cov hmoov av tawm ntawm qhov chaw ntawm lub kaum pob kws thiab lub siab phom siab. Tom qab lub substrate yog qhuav qhuav, lub saum npoo nrog theem ntawm caulking, thiab lub caulking ib feem yog yuav tsum tau ua kom tau los ntawm lub kaum pob zeb li lub kaum tom qab cov khoom siv caulking solidified. Tom qab ntawd tshem tawm cov nplaum ntawm cov av txhuam los yog yob ib daim qauv primer rau kev siv. Tus txheej txheem rov pib dua yog txog li 24 teev thiab tsawg kawg 3 teev.
2. Kev kho cov hlau substrate: Ua ntej sandblast lub substrate rau Sa2.5 qib, siv epoxy putty mus rau theem cov tsis xws luag xws li welds, ua tag nrho substrate du kev hloov, thiab lwm yam. Epoxy putty yog solidified thiab ces grinded nrog lub kaum sab nrauv. Caij, ces ntxuav lub substrate yob los yog txhuam ob cov piv primers.
