Dab tsi yog mortar qhuav hauv chemistry?
Qhuav mortar yog ib hom kev tsim khoom siv rau kev khi thiab khi cov khoom siv hauv tsev xws li cib, blocks, thiab pob zeb. Nws yog ib qho kev sib xyaw ntawm cov cement, xuab zeb, thiab lwm yam khoom siv ntxiv, thiab siv los ua cov ntaub ntawv los tuav cov khoom ua ke. Cov mortar qhuav yog siv rau ntau yam kev siv, xws li masonry, plastering, thiab tiling.
Qhuav mortar yog sib xyaw ntawm cov cement, xuab zeb, thiab lwm yam khoom ntxiv, xws li txiv qaub, gypsum, thiab dej. Cov cement ua raws li kev khi, thaum cov xuab zeb muab cov khoom siv ntau. Lwm cov khoom siv ntxiv yog siv los hloov cov khoom ntawm cov tshuaj khib, xws li nws lub zog, kev ua haujlwm, thiab dej tsis kam. Tus nqi ntawm txhua yam khoom siv hauv kev sib xyaw yog nyob ntawm daim ntawv thov thiab cov khoom xav tau ntawm cov mortar.
Hom mortar qhuav feem ntau yog Portland cement mortar, uas yog tsim nrog Portland cement, xuab zeb, thiab dej. Hom mortar no yog siv rau ntau yam kev siv, xws li masonry, plastering, thiab tiling. Nws kuj yog siv rau grouting thiab sau cov pob qij txha ntawm cib thiab pob zeb.
Lwm hom mortar qhuav muaj xws li txiv qaub mortar, gypsum mortar, thiab masonry cement. Txiv qaub mortar yog siv rau masonry thiab plastering, thiab yog ua nrog txiv qaub, xuab zeb, thiab dej. Gypsum mortar yog siv rau tiling thiab yog tsim nrog gypsum, xuab zeb, thiab dej. Masonry cement yog siv rau masonry thiab yog ua nrog Portland cement, txiv qaub, thiab xuab zeb.
Cov mortar qhuav yog npaj los ntawm kev sib xyaw cov khoom xyaw qhuav hauv ib qho khoom tov. Cov khoom xyaw yog tov kom txog thaum ib tug uniform sib xws. Qhov sib tov yog npaj txhij los siv.
Thaum siv cov tshuaj khib nyiab qhuav, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov chaw tsim khoom cov lus qhia rau kev sib xyaw thiab kev siv. Lub mortar yuav tsum tau muab sib xyaw thiab siv raws li cov chaw tsim khoom cov lus qhia kom ntseeg tau tias cov txiaj ntsig zoo tshaj plaws.
Qhuav mortar yog ntau yam khoom siv uas siv rau ntau yam kev siv. Nws yog ib qho yooj yim mus use thiab muab ib tug muaj zog, ruaj khov daim ntawv cog lus ntawm lub tsev cov ntaub ntawv. Nws yog ib qho tseem ceeb uas yuav tau ua raws li cov chaw tsim khoom cov lus qhia thaum siv cov tshuaj khib nyiab kom ntseeg tau tias cov txiaj ntsig zoo tshaj plaws.
