HPMC rau EIFS Mortar

HPMC sawv cev rau hydroxypropyl methylcellulose thiab yog ib qho khoom siv ntxiv hauv cov khoom siv hauv tsev, suav nrog Sab nrauv Rwb thaiv tsev thiab Finishing System (EIFS) mortars. EIFS yog cov txheej txheem cladding uas muab rwb thaiv tsev thiab kho kom zoo nkauj rau cov phab ntsa sab nrauv ntawm cov tsev.

Ntxiv HPMC rau EIFS mortar formulations txhim kho ntau yam khoom thiab txhim kho lawv cov kev ua tau zoo. Qee qhov txiaj ntsig tseem ceeb ntawm kev siv HPMC hauv EIFS mortars suav nrog:

Kev tuav dej: HPMC ua tus neeg saib xyuas dej, tso cai rau cov mortar khaws cov dej kom zoo rau lub sijhawm ntev. Qhov no pab cov cement kom hydrate zoo dua thiab ua kom muaj kev kho kom zoo, uas yog qhov tseem ceeb rau kev txhim kho cov khoom siv dag zog.

Kev ua haujlwm tau zoo: HPMC ua kom muaj peev xwm ua haujlwm tau zoo thiab sib xws ntawm EIFS mortars, ua kom yooj yim rau kev sib xyaw, thov thiab sib kis. Nws pab kom ua tiav qhov du thiab txawm tias zoo nkauj ntawm qhov chaw.

Adhesion: HPMC txhim kho qhov adhesion ntawm EIFS mortars rau ntau yam substrates, nrog rau cov rwb thaiv tsev thiab cov primers. Nws ua rau kom muaj zog ntawm daim ntawv cog lus thiab txo txoj hauv kev ntawm delamination lossis tawg.

Sag Resistance: Qhov sib ntxiv ntawm HPMC pab tiv thaiv EIFS mortar los ntawm sagging los yog collapsing ntawm ntsug nto. Nws txhim kho tus cwj pwm thixotropic ntawm mortar kom nws tseem nyob rau hauv qhov chaw thaum lub sij hawm tsim kho yam tsis muaj ntau deformation.

Crack resistance: HPMC tuaj yeem txhim kho qhov tawg ntawm cov tshuaj khib nyiab, txhim kho nws cov kav ntev thiab lub neej. Nws pab txo qis shrinkage thiab tswj cov kab nrib pleb uas tsim vim ziab lossis cua sov txav.

Flexibility: Los ntawm kev koom nrog HPMC, EIFS mortars tau yooj yim, uas yog qhov tseem ceeb kom haum rau lub tsev txav thiab thermal expansion / contraction yam tsis muaj kev puas tsuaj loj.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov tseeb ntawm HPMC siv thiab cov qauv ntawm EIFS mortar yuav txawv nyob ntawm seb yam khoom xws li cov khoom xav tau, cov xwm txheej huab cua thiab cov cai hauv zos. Cov neeg tsim khoom ntawm EIFS systems feem ntau muab cov lus qhia thiab cov lus pom zoo rau kev koom ua ke HPMC lossis lwm yam khoom ntxiv rau hauv lawv cov khoom mortar.
