Ukugqoka okungangenwa manzi kwe-polyurethane kanye nokugqoka okungangenwa manzi kwe-acrylic kuyizinto ezimbili ezivamile zokugqoka ezingangenwa manzi. Zinomehluko omkhulu ekwakhiweni kwezinto, izici zokwakha kanye nezinkambu ezisebenzayo.
Okokuqala, maqondana nokwakheka kwezinto, izembozo ezingangeni manzi ze-polyurethane zivame ukwakhiwa yi-polyurethane resin, izinyibilikisi kanye nezengezo, futhi zinokuthamba okuphezulu kanye nokumelana nesimo sezulu. Izembozo ezingangeni manzi ze-Acrylic zakhiwe yi-acrylic resin, izigcwalisi kanye nezengezo. Zibonakala ngokoma okusheshayo kanye nokusebenza kahle kokwakha ifilimu.
Okwesibili, ngokwezici zokwakha, izembozo ezingangeni manzi ze-polyurethane zivame ukudinga izinga eliphezulu lobuchwepheshe ngesikhathi sokwakha, zidinga ukwakhiwa endaweni ekahle kakhulu, futhi zibe nezidingo eziphakeme zokwelashwa kobuso besisekelo. Izembozo ezingangeni manzi ze-acrylic kulula ukwakhiwa futhi zingakhiwa ngaphansi kwezimo ezijwayelekile, futhi zinezidingo eziphansi kakhulu ebusweni besisekelo.
Ngaphezu kwalokho, maqondana nezinkambu ezisebenzayo, ngoba ukugqoka okungangenwa yi-polyurethane kunokuqina okuphezulu kanye nokumelana nesimo sezulu, kufanelekile ezindaweni ezidinga ukuvikelwa isikhathi eside futhi ezibhekene nokucindezeleka okukhulu, njengophahla, izindlu zangaphansi, njll. Ukugqoka okungangenwa yi-acrylic kufanelekile ekuvikelweni kokuvikela amanzi esakhiweni esijwayelekile futhi kungakhiwa ngokushesha. Kufaneleka kwezinye izikhathi lapho isikhathi sokwakha sifushane futhi kudingeka ukumbozwa okusheshayo.
Kukhona umehluko osobala phakathi kokugqoka okungangenwa manzi kwe-polyurethane kanye nokugqoka okungangenwa manzi kwe-acrylic ngokwesakhiwo sezinto, izici zokwakha kanye nezinkambu ezifanele. Ngaphambi kokwakha, ukugqoka okungangenwa manzi okufanele kudinga ukukhethwa ngokwezidingo ezithile zephrojekthi.
