Qhuav mortar yog ib qho kev sib xyaw ntawm cov ntaub ntawv cementitious (cement, ya tshauv, slag hmoov, thiab lwm yam), tshwj xeeb graded zoo aggregates (quartz xuab zeb, corundum, thiab lwm yam., thiab tej zaum yuav tsum tau lub teeb granules, nthuav perlite, nthuav vermiculite, thiab lwm yam. ) thiab admixtures yog uniformly tov nyob rau hauv ib tug tej yam kev faib ua feem, thiab ces packed nyob rau hauv lub hnab, chim los yog muab nyob rau hauv bulk nyob rau hauv qhuav hmoov lub xeev raws li ib tug lub tsev khoom.
Muaj ntau ntau hom kev lag luam mortar, xws li qhuav hmoov mortar rau masonry, qhuav hmoov mortar rau plastering, qhuav hmoov mortar rau hauv av, tshwj xeeb qhuav hmoov mortar rau waterproofing, tshav kub preservation thiab lwm yam hom phiaj. Txhawm rau ua kom tiav, cov tshuaj khib nyiab qhuav tuaj yeem muab faib ua cov khoom sib xyaw qhuav (masonry, plastering thiab av qhuav-sib xyaw mortar) thiab tshwj xeeb qhuav-sib xyaw mortar. Tshwj xeeb qhuav-siv mortar muaj xws li: tus kheej-leveling pem teb mortar, hnav-resistant pem teb cov ntaub ntawv, inorganic caulking neeg sawv cev, waterproof mortar, resin plastering mortar, pob zeb nto tiv thaiv cov ntaub ntawv, xim plastering mortar, thiab lwm yam.
Yog li ntau cov mortars qhuav qhuav yuav tsum muaj cov khoom sib txawv ntawm ntau hom thiab cov txheej txheem sib txawv ntawm kev txiav txim kom raug tsim los ntawm ntau qhov kev sim. Piv nrog rau cov pob zeb sib xyaw ua ke, cov khoom siv khib nyiab qhuav tuaj yeem siv rau hauv cov hmoov nplej, thiab qhov thib ob, lawv tau soluble hauv dej txias, los yog maj mam yaj nyob rau hauv qhov kev txiav txim ntawm alkalinity kom siv lawv cov txiaj ntsig.
Redispersible latex hmoov feem ntau yog cov hmoov dawb nrog qhuav fluidity, nrog cov hmoov tshauv ntawm li 12%, thiab cov hmoov tshauv feem ntau yog los ntawm tus neeg sawv cev tso tawm. Qhov loj me me ntawm cov hmoov polymer yog li ntawm 0.08mm. Tau kawg, qhov no yog qhov loj ntawm emulsion particle aggregate. Tom qab redispersing hauv dej, qhov luaj li cas ntawm cov emulsion particle yog 1 ~ 5um. Qhov loj me me ntawm cov emulsion hais siv ncaj qha rau hauv daim ntawv ntawm emulsion feem ntau yog hais txog 0.2um, yog li qhov loj me me ntawm emulsion tsim los ntawm cov hmoov polymer yog loj heev. Lub luag haujlwm tseem ceeb yog kom ua kom cov kev sib khi ua kom muaj zog ntawm cug, ua kom zoo dua qub, tawg, thiab txhim kho cov dej ua kom huv thiab ruaj khov ntawm cug.
Lub polymer redispersible polymer hmoov tam sim no siv nyob rau hauv qhuav hmoov mortar mas muaj xws li cov nram qab no hom:
(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, thiab lwm yam, feem ntau yog vinyl acetate-ethylene copolymer hmoov.
