Silicate xim tsev adorn lub facade ntawm lub tsev me

Lub coatings ua rau lub hauv paus ntawm silicate xim tsev muaj ob peb txawv thaj chaw: lawv muaj lub siab vapor permeability, qhuav sai sai. Ya uas accumulates nyob rau hauv lub caij ntuj no nyob rau hauv lub phab ntsa, tsis txhob ua puas lub cib thiab plaster. Zoo pass carbon dioxide thiab tsis txhob ncua lub curing txheej txheem plaster. Cov txheej tsis hlawv, sib nrug los ntawm hais tias nws tsis emit ib tug ntau yam ntawm teeb meem tshuaj. Tej zoo-silicate xim thov mus rau qhov chaw nrog ib tug xav alkaline Cheebtsam (txiv qaub plaster). Cov qualities kom ib tug ntev kev pab cuam lub neej ntawm qhov chaw.

Qhov tsis zoo ntawm cov dyes muaj xws li lub cev tsis mus thov lawv nyob rau hauv lub qub txheej rau ib tug organic hauv paus ntawm lub teb tsis muaj adhesion.

Silicate xim - ib ncua kev kawm ntawm fillers thiab pigments nyob rau hauv aqueous lub ntsiab ntawm sodium silicates thiab poov tshuaj. Lub silicates yog cov ntsev ntawm silicic acids yog muaj zog heev. Lawv yog cov tsawg npaum li cas thee yog li ntawd yooj yim moog los ntawm cov tshuaj tiv thaiv nrog cov pa roj carbon dioxide, uas yog muaj nyob rau hauv cov huab cua. Cov uas ua silica huab yog sai loses dej thiab ntaub ntawv ib tug ntxeem tau txheej uas muaj pob zeb ntais oxide. Nyob rau hauv lub tsim ntawm silicic acid thiab nws lub cev qhuav dej tshuaj tiv thaiv yog cai nrog tus hais txoj kev ua rau txheej pigments, fillers thiab ib tug inorganic substrate. Tshwj xeeb yog active silicic acid thiab silicates nrog lub zinc thiab calcium tebchaw. Yog hais tias peb xav txog hais tias calcium hydroxide - yog qhov tseem ceeb feem ntawm plasters thiab concretes, cov kev ntawm tej chaw silicate xim tsev ua rau yus lub creation ntawm ib tug monolithic txheej txheej sib bound.

Silicate xim, los yog es lawv lub zog, yog kev lom zem ntau nyob rau ntawm thaj chaw ntawm lub thov kua iav. Feem ntau cov dej-resistant high-quality xim koj yuav tau txais los ntawm kev siv poov tshuaj iav. Nws tseem muaj lwm silicates, tab sis lawv yog kim heev rau zus tau tej cov xim thiab cov kua roj vanish cov ntaub ntawv. Yuav kom silicate xim tsev khaws lawv cov hauj lwm zoo thiab hais tias lawv yuav tau mus thov mus rau lub txheej on ib tug organic hauv paus, ntxiv nyob rau hauv lawv cov muaj pes tsawg leeg yog tswvcuab acrylic dispersion, whereby lub tau cov xim tsev uas muaj lub siab vapor permeability, zoo heev adhesion rau coatings rau qub organic-raws thiab mineral chaw .

Ib tug tshiab hom ntawm cov xim muaj hlau coatings - silicate xim - siv nyob rau hauv peb lub sij hawm tau txais txaus dav. Thaum muab rau lawv, txhuas los yog zinc, lawv tau anticorrosive zog. Qhov no hom ntawm txheej yog siv nyob rau hauv plaster phab ntsa. Tsis tas li ntawd, lawv sib tham zoo nrog lub pob zeb, ua vaj tse, tej hub, slate thiab lwm qhov chaw yog zoo txeem rau hauv tus qauv ntawm tus nto raug kho, tiam sis yuav tau cov neeg pluag qho hwj chim, yog li ntawd yuav tsum tau nce number case noj.

Yuav tsum tau ceev faj thaum ua hauj lwm nrog silicate xim. Lawv muaj txog li kaum feem pua ntawm cov alkali. Yog hais tias number case tau txais nyob rau hauv koj daim tawv nqaij los yog nyob rau hauv koj lub qhov muag, tej zaum koj yuav muaj kev o. Yog li ntawd, thaum ua hauj lwm nrog cov xim tsev yuav tau tiv thaiv ob lub qhov muag. Nws yog ib advisable mus siv resperatora. Yog hais tias number case tau txais mus rau hauv lub qhov muag, ib qho mob ceev yuav tsum tau yaug nrog dej txias, thiab tom qab siv los ntxuav nrog xab npum.
