Txawm tias muaj kev loj hlob sai ntawm kev tshawb fawb hauv thaj chaw ntawm cov khoom siv hauv tsev, gypsum plaster, uas tib neeg tau siv sijhawm ntev, tsis tso nws txoj haujlwm. Lub Scope ntawm nws daim ntawv thov tseem dav heev. Nws yog ua los ntawm gypsum binders. Nws yog siv rau kev ua tiav kev ua haujlwm hauv tsev hauv tsev (tsis muaj cov av noo siab) rau qib kab rov tav, ntsug thiab lwm qhov chaw. Nws yog siv los ua lub hauv paus rau kev siv cov tshuaj pleev xim los yog cov hniav zoo nkauj.
Gypsum plaster yog siv los ua tiav cov chaw ua haujlwm, khw muag khoom thiab thaj chaw nyob. Kev siv cov khoom siv no ua rau nws muaj peev xwm kom tau txais qhov zoo tshaj plaws ntawm qhov chaw, uas, yog tias nws tsis suav nrog kev ua haujlwm putty, ces txo lawv mus rau qhov kawg. Tom qab ua tiav nrog cov plaster no, cov phab ntsa thiab qab nthab tau npaj txhij rau kev siv cov txheej txheem zoo nkauj, xws li cov xim pleev xim rau cov qauv lossis cov xim zoo nkauj, cov duab phab ntsa, cov plaster zoo nkauj. Cov khoom no muab siab adhesion nrog ntau yam khoom siv kho kom zoo nkauj. Hauv qhov no, qhov tshwm sim ntawm cov kab nrib pleb yog qhov tsawg heev.hauv txheej plaster.
Piv rau lwm yam ntawm cov khoom tiav uas npaj rau kev kho saum npoo, gypsum plaster muaj qhov zoo hauv qab no: nws muab cov kev ua haujlwm ntawm plastering (surface leveling) thiab kev npaj rau kev ua tiav cov txheej zoo nkauj (putty) hauv ib kauj ruam; tso cai rau ib daim ntawv thov rau theem saum npoo ntawm cov txheej tuab tuab (txog 10 cm) yam tsis muaj kev pheej hmoo ntawm kev tawg lossis tev; nws lub ntiajteb txawj nqus yog 2.5 p. tsawg dua cement plaster.
Gypsum plaster tsis yog shrinking, yog li cov kab nrib pleb tsis tshwm hauv nws. Cov kev daws teeb meem los ntawm nws muaj siab plasticity thiab kev txav mus los, muab kev ua haujlwm ntau ntxiv. Nyob rau hauv ib qho kev ua haujlwm, ib tus neeg ua haujlwm nrog cov txheej txheem ntawm daim ntawv thov tuaj yeem ua tau txog li 25 sq.m., thiab nrog ib tus neeg kho tshuab - txog li 50 sq.m. plaster.
Gypsum plaster yog qhov zoo tagnrho rau qib qab nthab thiab lwm qhov chaw kab rov tav. Txij li cov khoom no yog ntxeem tau, nws tso cai rau cov dej vapors nyob rau hauv nws los yog hauv chav tsev kom tau txais kev ywj pheej, uas tsim kom muaj qhov cua ntawm cov txheej txheem tiav thiab lub tsev. Yog li, qhov sib npaug microclimate yog tsim nyob rau hauv cov chav nrog xws li tiav.
Tsis zoo li cov cement coatings, gypsum plaster muaj qis coefficient ntawm suab thiab thermal conductivity. Cov khoom tiav no yog qhov zoo tshaj plaws rau kev siv tshuab.daim ntawv thov. Ua ke nrog ntau yam primers, nws muaj peev xwm daws tau qhov teeb meem ntawm plastering pob zeb nto thiab cov neeg uas muaj du nto yam tsis muaj kev siv cov reinforcing mesh. Gypsum plasters kuj tuaj yeem siv rau ntawm qee qhov muag muag. Tsis muaj kev pheej hmoo ntawm kev tshem tawm thaum siv lawv.
Gypsum plaster ntawm phau ntawv thov yog npaj rau daim ntawv thov nrog cov cuab yeej tes. Feem ntau txoj kev ua tiav no yog siv hauv cov chav me me. Muaj lwm yam khoom siv tiav - gypsum universal plaster. Nws kuj tseem siv tau rau kev siv tshuab siv tshuab siv tshwj xeeb rau ntawm thaj chaw loj.
Muaj ntau ntau yam ntawm gypsum plaster los ntawm cov tuam ntxhab sib txawv. Yuav luag txhua tus ntawm lawv yog ib puag ncig tus phooj ywg. Ua ntej thov rau saum npoo, qhuav mix yog diluted nrog dej. Cov tshuaj yog siv nyob rau hauv ib teev. Nws qhov nruab nrab noj yog 1 kg / sq.m. (nrog ib txheej ntawm 1 mm). Qhuav gypsum sib tov yog muag, raws li txoj cai, nyob rau hauv daim ntawv lub hnab ntawm txawv hnyav.
