Nrog kev pab los ntawm cov tebchaw zoo li no, koj tuaj yeem ua tiav ib qho chaw tiaj tiaj nyob rau theem kawg. Thaum piv nrog cov cement"kwv tij", ces cov gypsum compositions qhuav sai heev thiab tsis ntsws. Hom putty no yuav tsum tau siv sai li sai tau, vim tias nws tuaj yeem pib qhuav txawm tias ua ntej siv rau saum npoo.
Cov khoom sib xyaw zoo li no yog siv rau hauv chav sov thiab qhuav, vim tias gypsum tsis kam ya raws thiab o ntawm dej. Yog li ntawd, nws tsis tuaj yeem siv rau kev kho kom zoo nkauj sab nraum zoov. Tsis muaj teeb meem impurities ntawm cov khoom xyaw, cov khoom muaj kev nyab xeeb rau tib neeg noj qab haus huv. Yog tias qhov saum npoo tau kho nrog qhov muaj pes tsawg leeg, cov pwm yuav tsis tshwm sim ntawm nws, thiab txheej yuav zoo kawg nkaus dhau ntawm huab cua. Cov khoom siv tsis kub hnyiab, tab sis muaj zog tsawg thiab tsis tuaj yeem tiv taus qhov kub thiab txias.
Polymer putties
Yog tias koj yuav siv putty rau kev kho, hom thiab lub hom phiaj ntawm cov khoom no yuav tsum raug txiav txim siab.

Cov tshuaj sib xyaw ua ke cov txiaj ntsig tseem ceeb ntawm cov khoom sib tov yav dhau los thiab yuav luag tsis muaj qhov tsis zoo. Yuav kom meej meej, tsuas muaj ib qho kev rho tawm - tus nqi.
cov tshuaj polymer-based yog kim tab sis muaj ntau yam. Lawv yog cov ruaj khov, tsis ntshai ntawm qhov kub thiab txias thiab noo noo, qhuav sai sai thiab muaj cov qib siab elasticity. Thaum lub sij hawm thov, koj yuav txaus siab xav tsis thoob los ntawm qhov tsawg noj ntawm cov muaj pes tsawg leeg. Siv cov tshuaj no, koj tuaj yeem ua tiav daim iav yuav luag. Hom putty no rauKev siv sab nraum zoov yog qhov zoo, vim tias nws muaj dej tsis kam thiab muaj lub zog siab.
Yuav ua li cas xaiv putty rau nws lub hom phiaj
Cov hom putties teev saum toj no kuj tuaj yeem faib raws li lawv lub hom phiaj. Nyob ntawm thaj tsam ntawm kev siv, cov kev daws teeb meem yuav muaj cov khoom xyaw ntawm cov feem sib txawv thiab qhia txog qhov muaj cov plasticizers, nrog rau cov khoom siv ntxiv. Xav txog cov hom putties rau lub qab nthab thiab phab ntsa, koj tuaj yeem faib lawv mus rau hauv:
- pib;
- universal;
- finishing.
Tus qub yog siv rau theem, thaum kawg yog siv los ua ib txheej zoo nkauj.
pib putty
Nws yog siv rau thawj txheej, raws li nws tso cai rau koj mus rau theem saum npoo tom qab plastering.
