Polyurethane waterproof coating uye acrylic waterproof coating maviri akajairwa kusapinda mvura.Ivo vane misiyano yakakura mukuumbwa kwezvinhu, maitiro ekuvaka uye minda inoshanda.
Chekutanga, maererano nekuumbwa kwezvinhu, polyurethane machira asingapindi mvura anowanzo kuumbwa nepolyurethane resin, zvinonyungudutsa uye zvinowedzera, uye ane kukwirira kwepamusoro uye kusagadzikana kwemamiriro ekunze.Acrylic waterproof coating inoumbwa ne acrylic resin, fillers uye additives.Iyo inoratidzirwa nekuomeswa nekukurumidza uye yakanaka yekugadzira firimu kuita.
Chechipiri, maererano nemaitiro ekuvaka, polyurethane machira asingapindire mvura anowanzoda yakakwira tekinoroji panguva yekuvaka, inoda kuvakwa munzvimbo yakanyanya kunaka, uye ine zvinodiwa zvepamusoro zvekugadziriswa kwepasi.Acrylic waterproof coating iri nyore kugadzira uye inogona kuvakwa pasi pezvakajairwa mamiriro, uye ine yakaderera zvinodikanwa pachigadziko.
Uyezve, maererano neminda inoshandiswa, nokuti polyurethane inoputira mvura ine elasticity yakakwirira uye kusagadzikana kwemamiriro ekunze, inokodzera nzvimbo dzinoda kuchengetedzwa kwenguva refu uye dziri pasi pekunetseka kukuru, zvakadai sematenga, dzimba dzepasi, nezvimwewo. Acrylic waterproof coating yakakodzera. ye general building kudzivirira mvura uye inogona kuvakwa nekukurumidza.Yakakodzera kune dzimwe nguva apo nguva yekuvaka ipfupi uye kufukidzwa nekukurumidza kunodiwa.
Pane misiyano iri pachena pakati pe polyurethane mvura isingapindi mvura uye acrylic machira asingapindi mvura maererano nekuumbwa kwezvinhu, maitiro ekuvaka uye minda inoshanda.Kusati kwavakwa, machira akakodzera asingapindi mvura anofanira kusarudzwa maererano nezvinodiwa zveprojekiti.
