Ingubo engangeni manzi yepolyurethane kunye nengubo engangeni manzi ye-acrylic zizinto ezimbini eziqhelekileyo ezingangeni manzi. Zinomahluko omkhulu kwindlela ezibunjwe ngayo izinto, iimpawu zokwakha kunye neendawo ezifanelekileyo.
Okokuqala, ngokwendlela izinto ezisetyenziswa ngayo, izinto ezigqunywe nge-polyurethane ezingangeni manzi zihlala zenziwe nge-polyurethane resin, izinyibilikisi kunye nezinye izinto, kwaye zinokuthamba okuphezulu kunye nokumelana nemozulu. Izinto ezigqunywe nge-acrylic ezingangeni manzi zenziwe nge-acrylic resin, izizalisi kunye nezinye izinto. Ziphawulwa kukomisa ngokukhawuleza kunye nokusebenza kakuhle kokwenza ifilimu.
Okwesibini, ngokweempawu zokwakha, ii-polyurethane manzi ezigqunywe nge-polyurethane zihlala zifuna umgangatho ophezulu wobugcisa ngexesha lokwakha, kufuneka zakhiwe kwindawo efanelekileyo, kwaye zibe neemfuno eziphezulu zokulungiswa komphezulu osisiseko. I-acrylic manzi egqunywe nge-acrylic kulula ukuyakha kwaye inokwakhiwa phantsi kweemeko eziqhelekileyo, kwaye ineemfuno eziphantsi kumphezulu osisiseko.
Ngaphezu koko, ngokweenkalo ezifanelekileyo, kuba i-polyurethane engangeni manzi ithambile kakhulu kwaye inokumelana nemozulu, ifanelekile kwiindawo ezifuna ukhuseleko lwexesha elide kwaye ziphantsi koxinzelelo olukhulu, njengophahla, amagumbi angaphantsi komhlaba, njl. I-acrylic engangeni manzi ifanelekile ekuthinteleni amanzi kwizakhiwo ngokubanzi kwaye inokwakhiwa ngokukhawuleza. Ifanelekile kwezinye iimeko apho ixesha lokwakha lifutshane kwaye kufuneka ukugubungela ngokukhawuleza.
Kukho umahluko ocacileyo phakathi kweengubo ezingangeni manzi ze-polyurethane kunye neengubo ezingangeni manzi ze-acrylic ngokwendlela ezibunjwe ngayo izinto, iimpawu zokwakha kunye neendawo ezifanelekileyo. Ngaphambi kokwakha, iingubo ezingangeni manzi ezifanelekileyo kufuneka zikhethwe ngokweemfuno ezithile zeprojekthi.
