Cov txiaj ntsig ntawm kev siv HPMC hauv cov nplais nplaum

1. Txhim kho kev tsim kho

1.1. Txhim kho kev ua haujlwm

HPMC muaj lubrication zoo thiab adhesion. Ntxiv rau cov pobzeb nplaum tuaj yeem txhim kho kev ua haujlwm ntawm mortar, ua kom yooj yim rau khawb thiab du, thiab txhim khu kev ua haujlwm zoo thiab kev tsim kho ntawm cov neeg ua haujlwm tsim kho.

 

1.2. Tiv thaiv sagging

Thaum cov nplais nplaum siv rau ntawm qhov chaw ntsug, nws yooj yim rau sag vim nws qhov hnyav. HPMC zoo txhim kho cov cuab yeej tiv thaiv sagging ntawm cov nplaum los ntawm nws cov thickening thiab thixotropic zog, kom cov vuas tuaj yeem tswj tau qhov chaw ruaj khov tom qab paving thiab tiv thaiv slippage.

 

2. Txhim khu kev tuav dej

2.1. Txo cov dej poob

HPMC muaj kev tuav dej zoo heev. Nws tuaj yeem txo cov evaporation sai ntawm cov dej los yog nqus los ntawm lub hauv paus txheej hauv cov nplais nplaum, ua kom lub sijhawm qhib thiab hloov lub sijhawm ntawm cov nplaum, thiab muab cov neeg ua haujlwm tsim kho nrog kev ua haujlwm yooj yim dua.

 

2.2. Txhawb cov cement hydration cov tshuaj tiv thaiv

Kev tuav dej zoo pab cov cement kom muaj dej txaus thiab tsim cov khoom siv dej ntau dua, yog li txhim kho lub zog sib txuas thiab ua haujlwm ntev ntawm cov nplais nplaum.

 

3. Txhim kho kev sib raug zoo thiab lub zog

3.1. Txhim kho kev sib raug zoo interface qauv

HPMC tsim cov qauv zoo polymer network hauv cov nplaum, uas txhim kho kev sib raug zoo ntawm cov pobzeb nplaum thiab cov vuas thiab cov txheej txheej. Txawm hais tias nws yog cov vuas nqus los yog cov vuas uas tsis muaj dej nqus (xws li cov vuas vitrified thiab polished vuas), HPMC tuaj yeem muab kev sib txuas ruaj khov.

 

3.2. Txhim khu kev tawg kuj thiab yooj

Cov qauv polymer ntawm HPMC ua rau cov nplais nplaum muaj qee qhov yooj yim, uas tuaj yeem hloov kho me ntsis deformation lossis thermal expansion thiab contraction ntawm lub hauv paus txheej, thiab txo cov teeb meem zoo xws li hollowing thiab cracking los ntawm kev ntxhov siab concentration.

 

4. Txhim kho kev tsim kho kom haum

4.1. Haum rau ntau qhov chaw tsim kho

Nyob rau hauv cov huab cua tsis zoo xws li kub, qhuav lossis cua muaj zog, cov nplais nplaum zoo tib yam yuav qhuav sai heev, ua rau kev sib txuas tsis ua haujlwm. HPMC tuaj yeem ncua dej tsis zoo vim nws cov dej tuav tau zoo thiab ua cov yeeb yaj kiab, ua rau cov nplais nplaum yoog raws li kev tsim kho hauv ntau qhov chaw.

 

4.2. Muaj feem xyuam rau ntau yam substrates

Txawm hais tias nws yog cement mortar leveling txheej, pob zeb pob zeb, pobzeb qub nto lossis gypsum substrate, pobzeb adhesives nrog HPMC ntxiv tuaj yeem muab kev sib koom ua ke txhim khu kev qha, nthuav dav nws daim ntawv thov ntau yam.

 

5. Kev tiv thaiv ib puag ncig thiab kev nyab xeeb

HPMC yog cov khoom siv ntsuab thiab ib puag ncig zoo uas tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj nplaim taws, thiab yuav tsis ua rau muaj kev puas tsuaj rau ib puag ncig lossis tib neeg kev noj qab haus huv. Nws tsis tso cov khoom tsis zoo thaum lub sij hawm tsim kho, uas yog nyob rau hauv txoj kab nrog kev txhim kho lub tswv yim ntawm niaj hnub ntsuab vaj tse.

 

6. Kev lag luam thiab kev ua haujlwm ntev

Txawm hais tias tus nqi ntawm HPMC yog me ntsis siab dua li cov khoom siv ib txwm siv, nws txhim kho kev ua haujlwm ntawm cov nplais nplaum, txo cov nqi rov ua haujlwm thiab cov khoom siv pov tseg, thiab muaj txiaj ntsig zoo hauv kev lag luam ntev. Cov nplais nplaum nplaum zoo txhais tau tias kev saib xyuas tsawg dua, kev pab lub neej ntev dua thiab muaj txiaj ntsig zoo hauv tsev.
