Cov txiaj ntsig ntawm kev siv cov additives hauv cov nplais nplaum

Siv cov khoom siv ntxiv hauv cov nplais nplaum nplaum muaj ntau yam txiaj ntsig, txhim kho kev ua haujlwm, ua haujlwm tau zoo, thiab ua haujlwm ntev ntawm cov nplaum. Nov yog qee qhov txiaj ntsig tseem ceeb:

1. Txhim kho Adhesion: Cov khoom siv ntxiv tuaj yeem txhim kho kev sib raug zoo ntawm cov pobzeb nplaum thiab ntau yam substrates, suav nrog pob zeb, masonry, ceramics, thiab gypsum boards. Qhov no txhim kho tag nrho adhesion ntawm cov vuas, txo qhov kev pheej hmoo ntawm pobzeb detachment los yog debonding lub sij hawm.
2. Txhim Kho Kev Ua Haujlwm Zoo: Cov khoom siv ntxiv txhim kho kev ua haujlwm thiab tuav cov yam ntxwv ntawm cov nplais nplaum los ntawm kev hloov kho nws qhov sib xws, sib kis tau, thiab lub sijhawm qhib. Qhov no ua kom yooj yim sib tov, daim ntawv thov, thiab troweling, uas ua rau smoother thiab ntau yam pobzeb installation.
3. Txo Shrinkage thiab Cracking: Qee cov khoom ntxiv tuaj yeem pab txo qis qis thiab tawg hauv cov nplais nplaum los ntawm kev txhim kho nws cov cohesion thiab tensile zog. Qhov no ua rau kev txhim kho cov pobzeb ruaj khov thiab ruaj khov, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj kev cuam tshuam rau thermal lossis ya raws.
4. Kev tuav dej: Cov khoom siv ntxiv xws li cellulose ethers lossis hloov cov hmoov txhuv nplej siab ua cov dej tuav cov dej, ua kom lub sijhawm qhib ntawm cov nplaum thiab txhim kho nws txoj haujlwm. Qhov no tso cai rau cov neeg tsim khoom siv sijhawm ntau los kho cov pobzeb qhov chaw thiab ua kom muaj dej kom zoo ntawm cov cementitious binders, txhim kho adhesion thiab daim ntawv cog lus.
5. Txhim kho Flexibility: Qee cov additives impart yooj rau cov pobzeb nplaum formulations, tso cai rau lawv kom haum raws li substrate txav thiab thermal expansion yam tsis muaj cracking los yog debonding. Cov cuab yeej no yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm cov pobzeb kev teeb tsa hauv qhov chaw muaj kev ntxhov siab lossis dhau qhov tsis sib xws.
6. Kev tiv thaiv ib puag ncig: Cov khoom siv ntxiv tuaj yeem txhim kho cov dej tsis kam, khov-thaw tsis kam, thiab tshuaj tiv thaiv ntawm cov nplais nplaum, ua rau nws tsim nyog siv rau hauv qhov chaw ntub dej, ib puag ncig sab nrauv, thiab thaj chaw muaj kev cuam tshuam rau cov tshuaj hnyav lossis huab cua.
7. Enhanced Durability: Los ntawm kev txhim kho adhesion, yoog raws, thiab tsis kam mus rau ib puag ncig yam, additives pab txhawb rau tag nrho cov kav ntev thiab ntev ntawm cov pobzeb installation. Qhov no yuav pab txo cov kev xav tau ntawm kev saib xyuas thiab ua kom lub neej ntev ntawm cov nplais pobzeb.
8. Tswj Rheology: Additives ua raws li rheology modifiers, cuam tshuam qhov ntws thiab viscosity ntawm pobzeb nplaum. Lawv pab ua kom tiav daim ntawv thov sib xws thiab tiv thaiv sagging los yog slumping thaum lub sij hawm installation, xyuas kom meej cov kev pab them nqi thiab cov khoom siv.

Kev siv cov khoom siv ntxiv hauv cov nplais nplaum nplaum muaj ntau yam txiaj ntsig, suav nrog kev txhim kho adhesion, ua haujlwm tau zoo, ua haujlwm ntev, dej tuav, yoog raws, thiab ua haujlwm rau ib puag ncig yam. Cov txiaj ntsig zoo no ua rau muaj kev vam meej ntawm cov pobzeb kev teeb tsa thiab ua kom lub sijhawm ntev thiab ua kom zoo nkauj zoo nkauj.
