HEMC rau Pobzeb Adhesive MHEC C1 C2

Nyob rau hauv cov ntsiab lus ntawm pobzeb nplaum, HEMC hais txog Hydroxyethyl Methylcellulose, ib hom cellulose ether dav siv los ua ib qho tseem ceeb additive hauv cement-based tile adhesives.

Cov pobzeb nplaum ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg cov vuas rau ntau lub substrates, xws li pob zeb, cementitious backer boards, lossis cov pobzeb uas twb muaj lawm. HEMC tau ntxiv rau cov nplaum no los txhim kho lawv cov kev ua tau zoo thiab ua haujlwm tau zoo. Cov kev faib "C1" thiab "C2" muaj feem xyuam nrog European tus qauv EN 12004, uas faib cov nplais nplaum raws li lawv cov khoom thiab npaj siv.

Nov yog li cas HEMC, nrog rau C1 thiab C2 kev faib tawm, muaj feem cuam tshuam rau cov ntawv nplaum nplaum:

1. Hydroxyethyl Methylcellulose (HEMC):
   • HEMC ua raws li cov thickening, dej-retaining, thiab rheology-hloov tus neeg saib xyuas hauv cov ntawv nplaum nplaum. Nws txhim kho qhov adhesion, kev ua haujlwm, thiab lub sijhawm qhib ntawm cov nplaum.
   • Los ntawm kev tswj cov rheology ntawm cov nplaum, HEMC pab tiv thaiv sagging los yog slumping ntawm cov vuas thaum lub sij hawm installation thiab xyuas kom meej kev pab them nqi ntawm ob lub pobzeb thiab substrate nto.
   • HEMC tseem txhim khu kev sib koom ua ke thiab tensile lub zog ntawm cov nplaum, ua rau lub sijhawm ntev thiab kev ua haujlwm ntawm cov pobzeb installation.
2. C1 Classification:
   • C1 yog hais txog kev faib cov nplais nplaum nplaum raws li EN 12004. Adhesives cais raws li C1 yog tsim los kho cov pobzeb ceramic ntawm phab ntsa.
   • Cov nplaum no muaj qhov tsawg kawg nkaus tensile adhesion lub zog ntawm 0.5 N / mm² tom qab 28 hnub thiab tsim nyog rau kev siv sab hauv hauv qhov chaw qhuav lossis ntub dej.
3. C2 Classification:
   • C2 yog lwm qhov kev faib tawm raws li EN 12004 rau cov nplais nplaum. Adhesives cais raws li C2 yog tsim los kho cov vuas luaj ceramic ntawm ob phab ntsa thiab hauv pem teb.
   • C2 adhesives muaj qhov tsawg dua tensile adhesion zog piv rau C1 adhesives, feem ntau nyob ib ncig ntawm 1.0 N / mm² tom qab 28 hnub. Lawv tsim nyog rau kev siv sab hauv thiab sab nrauv, nrog rau cov chaw ntub dej tas li xws li cov pas dej da dej thiab cov ciav dej.

Hauv cov ntsiab lus, HEMC yog ib qho tseem ceeb ntxiv hauv cov ntawv nplaum nplaum, muab kev ua haujlwm zoo dua qub, adhesion, thiab kav ntev. Kev faib tawm C1 thiab C2 qhia qhov tsim nyog ntawm cov nplaum rau cov kev siv tshwj xeeb thiab ib puag ncig, nrog C2 nplaum muab lub zog ntau dua thiab muaj peev xwm siv dav dua piv rau C1 adhesives.
