Cov pobzeb nplaum ua lub luag haujlwm tseem ceeb hauv kev tsim kho niaj hnub no, muab cov adhesion muaj zog thiab yooj yim rau ntau daim ntawv thov pobzeb. Ib qho tseem ceeb additives siv nyob rau hauv pobzeb nplaum formulations yogHydroxyethyl Methyl Cellulose (HEMC), cellulose ether paub txog nws lub peev xwm los txhim kho kev ua tau zoo los ntawm kev hloov kho cov nplaum nplaum rheological thiab mechanical zog.
Cov khoom ntawm Hydroxyethyl Methyl Cellulose (HEMC)
HEMC yog non-ionic, dej-soluble polymer muab los ntawm cellulose. Nws yog dav siv nyob rau hauv kev tsim kho cov ntaub ntawv vim nwsthickening, dej tuav, thiab zaj duab xis-forming zog. Hauv cov nplais nplaum, KimaCell® HEMC ua haujlwm raws li arheology hloov kho, txhim kho tag nrho daim ntawv thov kev ua tau zoo.
Cov khoom tseem ceeb ntawm HEMC:
- Kev tuav dej:Tiv thaiv kom qhuav ntxov ntxov, ua kom muaj dej kom zoo ntawm cov cement.
- Thickening tus neeg sawv cev:Txhim khu kev sib xws thiab kev ua haujlwm.
- Txhim kho adhesion:Ua kom muaj zog sib txuas ntawm cov vuas thiab substrates.
- Lub sijhawm qhib:Tso cai rau kev ua haujlwm ntev dua rau kev tso cov pobzeb.

Qhov cuam tshuam ntawm HEMC ntawm Pobzeb Adhesive Performance
1. Kev txhim kho dej tuav
Kev tuav dej yog ib qho tseem ceeb ntawm cov nplais nplaum ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov cement-based adhesives. HEMC txhim kho cov dej tuav tau zoo, txo tus nqi evaporation thiab ua kom cov cement hydration txaus. Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv kub thiab qhuav tej yam kev mob, tiv thaiv cov nplaum tsis ua hauj lwm vim qhuav ntxov ntxov.
2. Txhim kho kev ua haujlwm thiab kev sib raug zoo
Qhov sib ntxiv ntawm HEMC txhim kho cov khoom rheological ntawm cov nplais nplaum, ua rau lawv yooj yim sib xyaw, sib kis, thiab ua haujlwm. Los ntawm kev tswj cov viscosity, HEMC tiv thaiv sagging nyob rau hauv ntsug daim ntaub ntawv, cia cov vuas nyob twj ywm nyob rau hauv qhov chaw yam tsis muaj slipping. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov phiaj xwm phab ntsa.
3. Nce Adhesion Strength
HEMC txhim kho lub zog sib txuas ntawm cov vuas thiab substrates los ntawm kev txhawb nqa dej zoo dua ntawm cov ntaub ntawv cementitious. Cov dej kom zoo ua kom muaj kev loj hlob ntawm cov matrix muaj zog, ua rau kev txhim kho adhesion kev ua tau zoo. Qhov no ua rau txo cov pobzeb detachment thiab zoo dua durability ntawm tiling system.
4. Qhib Sijhawm Ntxiv
Lub sijhawm qhib yog hais txog lub sijhawm uas cov vuas tuaj yeem hloov kho tom qab siv cov nplaum. KimaCell® HEMC ncua sij hawm qhib los ntawm kev ua kom cov dej ntws qeeb qeeb. Qhov no muab kev yooj yim thaum lub sij hawm installation, txo qhov kev pheej hmoo ntawm cov vuas detaching vim qhov chaw tsis raug.
5. Slump Resistance
Rau kev siv cov pobzeb ntsug, qhov kev tiv thaiv slump yog qhov tseem ceeb los tiv thaiv cov vuas los ntawm kev swb ua ntej teeb tsa. HEMC nce viscosity ntawm cov nplaum, kom ntseeg tau tias cov vuas nyob hauv qhov chaw tom qab thov. Cov cuab yeej no muaj txiaj ntsig tshwj xeeb hauv cov vuas loj thiab cov ntawv siv pob zeb hnyav.
6. Txhim kho Freeze-Thaw Stability
Pobzeb nplaum uas muaj HEMC nthuav tawm kev tiv thaiv kom khov-thaw mus. Lub polymer pab tswj cov nplaum ruaj khov hauv qhov kub thiab txias, tiv thaiv kev tawg thiab ua tsis tiav vim thermal expansion thiab contraction.
HEMCyog ib qho tseem ceeb additive nyob rau hauv cov pobzeb nplaum formulations, txhim khu kev ua tau zoo nyob rau hauv ntau txoj kev. Nws muaj peev xwmkhaws dej, txhim kho kev ua haujlwm, ntxiv dag zog rau adhesion, thiab ncua sijhawm qhibua rau nws indispensable nyob rau hauv niaj hnub tiling daim ntaub ntawv. Los ntawm kev ua kom zoo dua qhov concentration ntawm KimaCell® HEMC hauv cov nplais nplaum, cov tuam ntxhab tuaj yeem ua tiav cov khoom lag luam zoo tshaj plaws uas ua kom muaj kev ruaj khov, yooj yim ntawm daim ntawv thov, thiab txhim kho kev sib raug zoo. Kev nce qib yav tom ntej hauv cellulose ether thev naus laus zis tuaj yeem txhim kho nws lub luag haujlwm hauv kev tsim cov nplaum nplaum, ua kom cov nplais ua kom zoo dua thiab txhim khu kev qha.
