Ceiling vuas txig du qhov teeb meem ntawm thaj chaw - nws yog ib qho kev zoo thiab zoo nkauj zoo nkauj ntawm txoj kev ntsia lub qab nthab.
Cov yam ntxwv ntawm cov khoom qab nthab
Qab nthab vuas yog ua los ntawm cov ua npuas ncauj. Qhov zoo tshaj plaws xaiv - stamped khoom, lawv yog nias, lub zog ntawm cov khoom yog tsawg, lub thickness yog 6-8 mm. Hauv chav kawm muaj xws li ib rab diav ntim: ib lub thickness ntawm 9-14 hli, daim duab yog heev meej. Muaj lub zog ua tiav vim muaj kev kub ntxhov ntawm cov khoom. Qhov zoo tshaj plaws yog xam cov khoom siv ntau heev. Cov nplaim feem ntau imitates tus qauv ntawm ntoo, pob zeb ci, pob zeb. Muaj zog tshaj plaws, uas cuam tshuam rau cov nqi.
Thaum muas txojkev, koj yuav tsum ntxiv 10-15% rau kev txiav thiab seem. Nws tseem tsuas yog xaiv los ua li cas rau kua nplaum phaj ntawm nthuav polystyrene.
Dab tsi yog qhov zoo dua rau lo nplais pobzeb?
Cov kua nplaum rau ntawm cov dej muaj kev ruaj ntseg rau kev noj qab haus huv, tiam sis nrog lawv ntev dua qub, raws li lawv qhuav qhuav tas. Yog tias qhov kub tsis muaj tseeb, hauv qab tas, cov kab mob thiab cov fungus tuaj yeem tsim.
Kev txhim khu ntxiv ntawm kev txhim kho yog muaj kev zoo siab nrog cov kuab tshuaj (raws li cawv lossis acetone). Lawv yuav ceev thiab ntau txhim khu kev qha glued rau ntawm qhov chaw. Nws yog tsim nyog yuav tau coj mus rau hauv tus account tau deformations ntawm cov hniav thaum interacting nrog sib tov.
Adhesives xws li "melts" ua kom zoo dua thaum ua kom sov. Qhov no yog ib txoj kev zoo rau cov chav uas nws tau nquag ntxuav, vaum nce, piv txwv, rau chav ua noj.
Cov kua nplaum twg yog qhov zoo dua rau cov khoom qab nthab? Compound kua nplaum yog xam tag nrho. Epoxy thiab silicone puag (muaj ib tus ntxhiab ntse) lav daim nplaum kom yuav luag txhua qhov chaw. Nyob rau hauv ib tug txaus sib xws, qhov sib tov yog heev luv luv. Ua hauj lwm nrog qee cov sib xyaw, koj xav tau ib rab phom, uas cuam tshuam tus nqi ntawm kev teeb tsa.
Tsawg shrinkage, adhesion thiab noo noo kuj ua "kua tes" ib txoj kev nrov ntawm kev kho foam daim hlau. Yooj yim nkaum lub tsis meej ntawm lub qab nthab. Txhim kho cov phiajxwm, koj tuaj yeem xaiv qhov kawg ntawm cov ntaub qhwv (acrylic filler). Koj siv nws li lub kua nplaum, nws tseem nqaws tau cov nqaws dej.
