Plaster mixes yog cov khoom siv hauv tsev tsim rau cov phab ntsa plastering. Lawv yog siv rau ob qho tib si sab nraum zoov thiab sab hauv tsev. Cov khoom siv no tau siv txawm tias nrog cov neeg tsim cov pyramids. Cement, txiv qaub thiab gypsum mixs paub.
Hauv kev tsim kho niaj hnub no, plaster sib tov yog siv, ua los ntawm tib cov cement, txiv qaub thiab gypsum, tab sis nrog kev sib ntxiv ntawm ntau yam polymer additives, uas ua rau nws muaj peev xwm muab cov khoom siv ntxiv zog, noo noo tiv thaiv thiab tiv thaiv pwm thiab fungus.
Cov kws tshaj lij niaj hnub rau kev ua haujlwm tsis ua cov tshuaj plaster rau lawv tus kheej, tab sis siv cov npaj ua tiav. Cov no yog cov pob zeb qhuav qhuav uas tsim muaj kev lag luam thiab ntim rau hauv lub hnab ntawm 25-50 kilograms. Cov khoom tiav yog diluted nrog dej raws li cov lus qhia.
Plaster sib tov tuaj yeem yog cov hauv qab no:
Cement-lime - siv rau plastering phab ntsa ua los ntawm cib, pob zeb, ua npuas ncauj thiab roj blocks. Siv rau sab hauv (piv txwv li, sib tov ntawm M-25 - rauchav qhuav, M-50 - rau ntub dej) thiab sab nraum zoov ua haujlwm (rau facade - M-100). Cov khoom no yog tsim los ntawm cov cement, qhuav txiv qaub, xuab zeb thiab tshwj xeeb additives rau ya raws thiab plasticity.
Mixes nrog hluavtaws additives. Lawv txawv los ntawm kev nce plasticity thiab zoo adhesion rau lub hauv paus. Nws yog siv los ua thawj (hauv paus) phab ntsa plaster ntawm txhua yam khoom siv.
Sib tov rau kev ua haujlwm sab hauv - tsim rau plastering phab ntsa hauv chav nrog cov av noo siab. Nws tuaj yeem siv cov ntaub ntawv no los ntawm plaster.
Facade plaster mix. Nrog nce noo noo tsis kam. Muaj feem xyuam rau cib, qhob thiab cement-lime plaster.
Gypsum plaster sib tov yog tsim los rau pob zeb thiab cib. Siv sab hauv tsev thiab sab nraum lub tsev. Yuav siv tau los ntawm tes lossis los ntawm cov tshuab tshwj xeeb. Tom qab plastering nrog gypsum mortar, tsis tas yuav putty. Phab ntsa tuaj yeem pleev xim tam sim lossis wallpapered. Gypsum plaster yog siv yog tias nws tsis tsim nyog rau theem saum npoo.
Ntxiv rau cov hom tseem ceeb, kuj tseem muaj cov txheej txheem plaster tshwj xeeb uas muaj te-resistant lossis waterproofing zog. Frost-resistant yog tsim los rau leveling complex nto, withstands qis kub mus rau -15 degrees. Waterproofing tuaj yeem siv hauv tsev nrog cov av noo siab. Qhov sib tov no muaj cov yas siab heev.
Ua haujlwm nrog txhua hom plaster sib xyaw muaj nws tus kheej thev naus laus zis. Tab sis muaj qee yamcov cai yuav tsum tau ua. Phab ntsa npaj rau plastering yuav tsum tau ntxuav ntawm cov khoom qub thiab, yog tias tsim nyog, degreased. Ua ntej ua haujlwm, nws yog ib qho tsim nyog los txiav txim siab qhov nyuaj ntawm qhov chaw thiab cov txheej txheem ntawm plaster yuav siv li cas. Qhov no yog tsim nyog los npaj cov khoom tsim nyog. Tsis yog txhua qhov sib tov yog haum rau kev sib tw. Qhov nruab nrab, cov txheej plaster yog siv los ntawm 5 mus rau 20 hli, tab sis yuav tsum tau siv 30 hli txheej, qhov no yuav tsum muaj plaster tshwj xeeb. Cov khoom qhuav yog diluted nrog dej huv ntawm chav tsev kub thiab nplawm kom txog thaum homogeneous loj. Cov tsos mob ntawm cov pob qij txha yog qhov tsim nyog.
