I-Polyurethane yokwambathisa engangeni manzi kunye ne-acrylic yokugquma engenamanzi zizinto ezimbini eziqhelekileyo zokungangeni manzi.Zinolwahlulo oluphawulekayo ekubunjweni kwezinto eziphathekayo, iimpawu zokwakha kunye nemimandla esebenzayo.
Okokuqala, malunga nokubunjwa kwezinto eziphathekayo, iingubo ze-polyurethane ezingenamanzi zihlala zenziwe nge-polyurethane resin, i-solvents kunye ne-additives, kwaye zine-elasticity ephezulu kunye nokumelana nemozulu.I-Acrylic yokugquma kwamanzi ihlanganiswe ne-acrylic resin, iifayili kunye nezongezo.Ibonakaliswa ngokumisa ngokukhawuleza kunye nokusebenza kakuhle kwefilimu.
Okwesibini, ngokweempawu zokwakha, iingubo ze-polyurethane ezingenamanzi zihlala zifuna inqanaba eliphezulu lobugcisa ngexesha lokwakha, kufuneka lakhiwe kwindawo efanelekileyo ngakumbi, kwaye lineemfuno eziphezulu zokwenza unyango lwesiseko.I-Acrylic waterproof coating ilula ukwakha kwaye inokwakhiwa phantsi kweemeko eziqhelekileyo, kwaye ineemfuno eziphantsi kakhulu kwisiseko sesiseko.
Ngaphezu koko, ngokwemimandla esebenzayo, ngenxa yokuba i-polyurethane i-coating engenamanzi ine-elasticity ephezulu kunye nokumelana nemozulu, ifanelekile kwiindawo ezifuna ukukhuselwa kwexesha elide kwaye ziphantsi koxinzelelo olukhulu, njengophahla, amagumbi angaphantsi, njl. kwisakhiwo jikelele sokuthintela amanzi kwaye inokwakhiwa ngokukhawuleza.Ifanelekile kwezinye izihlandlo apho ixesha lokwakha lilifutshane kwaye kufuneka ugutyungelwe ngokukhawuleza.
Kukho iiyantlukwano ezicacileyo phakathi kweengubo ze-polyurethane ezingenamanzi kunye neengubo ze-acrylic ezingenamanzi ngokumalunga nokubunjwa kwezinto eziphathekayo, iimpawu zokwakha kunye nemimandla esebenzayo.Ngaphambi kokwakhiwa, iingubo ezifanelekileyo zokungena kwamanzi kufuneka zikhethwe ngokweemfuno ezithile zeprojekthi.
