Tsuas yog ob peb xyoos dhau los, kev kho thiab kho kom zoo nkauj ntawm phab ntsa tau ua tiav yooj yim heev: cov kab nrib pleb thiab cov kab nrib pleb tau muab khi nrog alabaster mortar, thiab cov tshiab tau muab khi los ntawm cov ntawv qub qub. Cov qauv tam sim no thiab thev naus laus zis ntawm kev kho thiab ua tiav cov haujlwm sib txawv, thiab feem ntau yog vim muaj ntau yam kev sib xyaw hauv tsev. Piv txwv li, ib qho ntawm cov khoom siv niaj hnub no yog cov khoom tiav, uas tso cai rau koj nqa cov phab ntsa kom zoo meej.
Cov yam ntxwv tshiab - tau txiaj ntsig zoo
Txhawm rau tshem tawm qhov tsis xws luag loj thiab cov phab ntsa tsis sib xws, plaster yog siv tam sim ntawd, uas yog tom qab ntawd npog nrog ib txheej ntawm pib putty sib tov. Tab sis cov ntaub ntawv no tsis tso cai kom ua tiav qhov xav tau smoothness, yog li "cov lus kawg" tseem nyob nrog cov txheej txheej ntawm phab ntsa. Nrog kev pab los ntawm nws, me me tsis xws luag yog tshem tawm tom qab pib sib tov thiab qhov kawg, yog li hais, zoo leveling ntawm qhov chaw. Kev ua tiav putty muaj qhov tsawg tshaj plaws ntawm cov feem, vim nws ua tiavxav tau smoothness. Qhov zoo ntawm cov phab ntsa yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm kev npaj rau tha xim, vim tsis muaj xim tuaj yeem npog txawm tias me ntsis pob. Qhov loj ntxiv ntawm "tiav" yog qhov tseeb tias nws muaj xim dawb thiab qhov no tso cai rau koj siv nws rau kev ua tiav cov ntaub ntawv ntawm txhua qhov ntxoov ntxoo thiab paub tseeb tias qhov kawg tshwm sim. Ntawm lwm yam, putty coated nrog primer ua kom zoo adhesion ntawm cov khoom tiav rau ntawm phab ntsa, thiab qhov no yog qhov lav tias tom qab qee lub sij hawm qhov ua tiav yuav tsis pib poob.
Tiav putty: tshuaj xyuas thiab cov lus pom zoo ntawm cov kws tshaj lij
Muaj peb txoj hauv kev xaiv cov khoom tiav - qhov no yog qhov loj ntawm cov feem, qhov ceev ntawm solidification thiab hom binder (gypsum, cement, polymer). Lub ntsiab ntawm cov qauv no yog qhov tseeb ntawm kev khi lub hauv paus ntawm qhov sib tov. Piv txwv li, cement tiav putty muaj cov dej tsis zoo, yog li nws tsim nyog siv hauv chav dej, chav dej thiab chav ua noj. Tab sis qhov tsis zoo ntawm cov khoom siv no yog nws txoj kev xav kom ntsws, thiab yog li nws yuav tsum tau siv rau hauv ob peb txheej. Tab sis gypsum putty tsis ntsws tag nrho, txawm li cas los xij, nws tsis zam qhov kub thiab txias heev. Cov txheej txheem thev naus laus zis tshaj plaws yog cov polymer tiav putty. Nws muaj plasticity siab, yog li nws yooj yim siv rau qhov chaw, ua rau lawv txawm. Tab sis qhov tsis zoo ntawm cov khoom siv no tuaj yeem suav tias yog nws tus nqi siab.
Cov cuab yeej ua tiav
Ua ntej siv cov txheej txheem tiav, cov phab ntsa yuav tsum tau primed. Nyob rau hauv tus txheej txheem ntawm kev ua hauj lwm, peb spatulas yuav tsum tau: nqaim (10-15 cm), dav (40-60 cm) thiab angular. Nrog ib tug me me spatula, lub tiav lawm sib tov yog sau los ntawm ib tug thoob thiab xa mus rau ib tug dav spatula, uas yog siv rau theem nws saum npoo. Lub kaum sab xis trowel ua rau nws yooj yim siv cov khoom siv rau cov ces kaum. Lub thickness ntawm ib txheej ntawm txheej yuav tsum tsis txhob ntau tshaj 2 hli, txwv tsis pub nws yuav tawg thaum qhuav. Kev noj cov khoom tiav rau ib square meter yuav, ntawm chav kawm, nyob ntawm qhov tuab ntawm txheej, tab sis qhov nruab nrab nws yog 1 kg ib 1 m2 2.
