Ko te kumete whakamaroke-whakaranu he whakakotahitanga o nga rawa cimentitious (sima, pungarehu rere, paura para, me etahi atu), nga kohinga pai kua tohua (kirikiri kiripaka, corundum, me etahi atu, me etahi wa ka hiahiatia he Granules marama, perlite kua whakawhānuihia, vermiculite kua whakawhānuihia, etc. ) me nga whakaurunga ka konatunatua kia rite ki tetahi ohanga, katahi ka kikii ki roto i nga peeke, peera, ka tukuna ranei i roto i te nuinga i roto i te ahua paura maroke hei taonga hanga whare.
He maha nga momo moata hokohoko, tae atu ki te paura paura maroke mo te masonry, te paura paura maroke mo te raima, te paura paura maroke mo te whenua, te paura paura maroke motuhake mo te parewai, te tiaki i te wera me etahi atu kaupapa. Hei whakarapopototanga, ka taea te wehea te moata whakauru maroke ki te moata whakaranu maroke noa (masonry, raima me te moata whakaranu maroke) me te moata whakaranu maroke motuhake. Ko te kumete whakamaroke-whakaranu motuhake kei roto: te kumete papa-a-whaiaro, he papanga papa-atete, he kaikawe parakore, he kumete parewai, he kumete raima raima, he mea whakamarumaru mata raima, he kumete raima tae, aha atu.
Na te maha o nga moata whakamaroke-whakaranuhia e hiahia ana ki te whakauru i nga momo momo rereke me nga momo mahi hei hanga ma te maha o nga whakamatautau. Ka whakatauritea ki nga whakaurunga raima tuku iho, ka taea anake te whakamahi i nga whakaurunga moata whakamaroke i roto i te ahua o te paura, tuarua, ka whakarewahia i roto i te wai matao, ka memeha haere ranei i raro i te mahi o te alkalinity ki te whakapau kaha.
Ko te paura latex redispersible te nuinga o te paura ma me te wai maroke, me te kiko o te pungarehu o te 12%, a ko te nuinga o te pungarehu ka puta mai i te kaihoko tuku. Ko te rahi o te matūriki o te paura polymer he 0.08mm. Ko te tikanga, koinei te rahi o te whakahiato matūriki whakaehunga. I muri redispersing i roto i te wai, te rahi matūriki angamaheni o te matūriki whakaehunga ko 1~5um. Ko te rahi matūriki angamaheni o te matūriki whakaehunga whakamahia tika i roto i te ahua o te whakaehunga ko te tikanga e pā ana ki 0.2um, na te rahi matūriki o te whakaehunga i hanga e te paura polymer he āhua nui. Ko te mahi matua ko te whakanui ake i te kaha honohono o te kumete, te whakapai ake i tona uaua, te rerekee, te kapiti aukati me te koretake, me te whakapai ake i te pupuri wai me te pumau o te kumete.
Ko te paura polymer redispersible polymer e whakamahia ana i tenei wa ki te moata paura maroke ko nga momo e whai ake nei:
(1) styrene-butadiene copolymer;
(2) Styrene-acrylic acid copolymer;
(3) vinyl acetate homopolymer;
(4) polyacrylate homopolymer;
(5) Styrene acetate copolymer;
(6) Vinyl acetate-ethylene copolymer, me etahi atu, ko te nuinga he paura vinyl acetate-ethylene copolymer.
