Dab tsi yog raw khoom ntawm phab ntsa putty?

Phab ntsa putty yog cov khoom siv nrov siv hauv ob qho tib si hauv tsev thiab kev lag luam. Nws yog cov khoom siv ntau yam uas yog siv los ua kom zoo nkauj thiab ua tiav cov phab ntsa sab hauv thiab sab nrauv ua ntej pleev xim lossis wallpapering. Phab ntsa putty yog tsim los ntawm ntau yam khoom siv raw uas sib xyaw ua ke los ua cov khoom sib xyaw zoo li tuab. Hauv tsab xov xwm no, peb yuav tham txog cov ntaub ntawv raw ntawm phab ntsa putty kom ntxaws.

Dawb cement:
Dawb cement yog cov khoom siv tseem ceeb siv hauv phab ntsa putty. Nws yog ib tug hydraulic binder uas yog tsim los ntawm finely av dawb clinker thiab gypsum. Cov cement dawb muaj qib siab ntawm cov xim dawb thiab cov ntsiab lus tsawg ntawm hlau thiab manganese oxide. Nws yog nyiam nyob rau hauv phab ntsa putty vim nws muab ib tug du tiav rau cov phab ntsa, muaj zoo adhesion zog, thiab yog resistant rau dej.

Marble hmoov:
Marble hmoov yog ib yam khoom los ntawm marble txiav thiab polishing. Nws yog finely av thiab siv nyob rau hauv phab ntsa putty txhim khu nws lub zog thiab durability. Marble hmoov yog cov ntxhia hauv ntuj uas muaj calcium ntau thiab muaj cov khoom sib txuas zoo. Nws pab txo qhov shrinkage ntawm putty thiab muab ib tug du tiav rau phab ntsa.

Talcum hmoov:
Talcum hmoov yog cov ntxhia mos uas siv rau hauv phab ntsa putty los txhim kho nws cov haujlwm ua haujlwm thiab txo cov viscosity ntawm cov sib tov. Nws yog finely av thiab muaj ib tug high degree ntawm purity. Talcum hmoov pab tau yooj yim daim ntawv thov ntawm putty thiab txhim kho nws adhesion rau phab ntsa.

Suav av nplaum:
Tuam Tshoj av nplaum, tseem hu ua kaolin, yog cov ntxhia pob zeb ntuj uas siv rau hauv phab ntsa putty ua cov muab tub lim. Nws yog finely av thiab muaj ib tug high degree ntawm whiteness. Tuam Tshoj av nplaum yog ib qho khoom siv pheej yig uas yog siv los txhim kho qhov ntau ntawm putty thiab txo nws cov nqi.

Mica hmoov:
Mica hmoov yog cov ntxhia ntuj uas siv rau hauv phab ntsa putty los muab cov glossy tiav rau phab ntsa. Nws yog zoo nyob rau hauv av thiab muaj ib tug high degree ntawm reflectivity. Mica hmoov pab txo cov porosity ntawm putty thiab muab kev tiv thaiv zoo rau dej.

Silica xuab zeb:
Silica xuab zeb yog cov ntxhia ntuj uas yog siv rau hauv phab ntsa putty ua cov muab tub lim. Nws yog finely av thiab muaj ib tug high degree ntawm purity. Silica xuab zeb pab txhim kho lub zog ntawm putty thiab txo nws cov shrinkage. Nws kuj pab txhim kho qhov adhesion ntawm putty rau phab ntsa.

Dej:
Dej yog ib qho tseem ceeb ntawm cov phab ntsa putty. Nws yog siv los sib tov cov ntaub ntawv raw ua ke thiab tsim cov khoom zoo li paste. Dej pab ua kom cov khoom sib txuas ntawm cov cement thiab muab qhov tsim nyog fluidity rau qhov sib tov.

Tshuaj additives:
Cov tshuaj additives yog siv rau hauv phab ntsa putty los txhim kho nws cov khoom thiab kev ua tau zoo. Cov additives muaj xws li retarders, accelerators, plasticizers, thiab waterproofing agents. Retarders yog siv los ua kom qeeb lub sij hawm ntawm lub putty, thaum accelerators yog siv los ua kom lub sijhawm teem sijhawm. Plasticizers yog siv los txhim kho kev ua haujlwm thiab txo cov viscosity ntawm putty, thaum cov tshuaj tiv thaiv dej yog siv los ua cov dej-resistant.

Methyl celluloseyog ib hom cellulose ether siv nyob rau hauv phab ntsa putty. Nws yog tsim los ntawm kev hloov kho tshuaj ntawm ntuj cellulose siv methanol thiab alkali. Methyl cellulose yog cov hmoov dawb, tsis muaj ntxhiab, thiab tsis qab ntsev uas yog soluble hauv dej thiab tsim cov kua dej ntshiab thiab khov. Nws muaj cov khoom tuav dej zoo thiab txhim kho kev ua haujlwm ntawm putty. Methyl cellulose kuj muab cov adhesion zoo rau ntau yam substrates thiab txhim kho lub zog tensile ntawm putty.

Hydroxyethyl cellulose yog lwm hom cellulose ether siv hauv phab ntsa putty. Nws yog tsim los ntawm kev hloov kho tshuaj ntawm ntuj cellulose siv ethylene oxide thiab alkali. Hydroxyethyl cellulose yog cov hmoov dawb, tsis muaj ntxhiab, thiab tsis qab ntsev uas yog soluble hauv dej thiab tsim cov kua dej ntshiab thiab khov. Nws muaj cov khoom tuav dej zoo thiab txhim kho kev ua haujlwm ntawm putty. Hydroxyethyl cellulose kuj muab cov adhesion zoo rau ntau yam substrates thiab txhim kho lub zog tensile ntawm putty.

Carboxymethyl cellulose kuj tseem siv rau hauv phab ntsa putty ua cov thickener thiab binder. Nws yog tsim los ntawm kev hloov kho tshuaj ntawm ntuj cellulose siv monochloroacetic acid thiab alkali. Carboxymethyl cellulose yog cov hmoov dawb, tsis muaj ntxhiab, thiab tsis qab ntsev uas yog soluble hauv dej thiab tsim cov kua dej ntshiab thiab khov. Nws muaj cov khoom tuav dej zoo thiab txhim kho kev ua haujlwm ntawm putty. Carboxymethyl cellulose kuj muab cov adhesion zoo rau ntau yam substrates thiab txhim kho lub zog tensile ntawm putty.

Hauv kev xaus, phab ntsa putty yog tsim los ntawm ntau yam khoom siv raw uas sib xyaw ua ke los tsim cov khoom zoo li paste. Cov khoom siv tseem ceeb hauv phab ntsa putty yog cov cement dawb, thaum lwm cov ntaub ntawv raw muaj xws li marble hmoov, talcum hmoov, Tuam Tshoj av nplaum, mica hmoov, silica xuab zeb, dej, thiab tshuaj additives. Cov ntaub ntawv nyoos no raug xaiv rau lawv cov khoom tshwj xeeb, xws li cov xim dawb, cov khoom sib txuas, ua haujlwm tau zoo, thiab ua haujlwm ntev, los muab cov xim zoo nkauj thiab zoo nkauj rau phab ntsa.
