Cov nyhuv thickening ntawm HEMC tuaj yeem ua kom cov viscosity ntawm cov nplaum, yog li txhim kho nws cov kev tsim kho. Los ntawm kev kho tus nqi ntawm HEMC ntxiv, cov nplaum tuaj yeem muaj cov thixotropy zoo thaum lub sij hawm tsim kho, uas yog, fluidity nce nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, thiab sai sai rov qab mus rau lub siab viscosity tom qab lub sab nraud quab yuam raug nres. Cov yam ntxwv no tsis tsuas yog pab txhim kho kev ruaj ntseg ntawm cov vuas ceramic thaum tso, tab sis kuj txo qhov tshwm sim ntawm slippage thiab ua kom lub smoothness thiab raug ntawm ceramic pobzeb tso.

c. Txhim kho kev sib raug zoo

HEMC tuaj yeem txhim kho cov txheej txheem sab hauv lub zog ntawm cov nplaum, yog li txhim kho nws cov txiaj ntsig kev sib raug zoo rau lub substrate thiab ceramic pobzeb nto. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho ib puag ncig nrog kub los yog high humidity, HEMC tuaj yeem pab cov nplaum tuav ruaj khov ua haujlwm. Qhov no yog vim HEMC tuaj yeem ua kom lub zog ruaj khov thaum lub sijhawm tsim kho, kom ntseeg tau tias cov tshuaj tiv thaiv hydration ntawm cov cement thiab lwm cov ntaub ntawv hauv paus ua haujlwm zoo, yog li txhim kho lub zog sib txuas thiab ua haujlwm ntev ntawm cov nplais nplaum.

3. HEMC ntau npaum li cas thiab kev ua haujlwm sib npaug

Tus nqi ntawm HEMC plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov nplais nplaum. Feem ntau hais lus, qhov sib ntxiv ntawm HEMC yog nyob nruab nrab ntawm 0.1% thiab 1.0%, uas tuaj yeem hloov kho raws li qhov sib txawv ntawm kev tsim kho thiab cov kev xav tau. Kev noj tsawg dhau yuav ua rau cov dej tuav tsis txaus, thaum noj ntau dhau yuav ua rau cov kua nplaum tsis zoo, cuam tshuam rau kev tsim kho. Yog li ntawd, hauv kev siv tswv yim, nws yog qhov yuav tsum tau ua tib zoo xav txog qhov chaw tsim kho, cov khoom siv hauv qab, thiab cov kev tsim kho zaum kawg, thiab kho tus nqi ntawm HEMC kom paub meej tias qhov viscosity, qhib lub sij hawm, thiab lub zog ntawm cov nplaum mus txog qhov zoo tagnrho.

4. Daim ntawv thov zoo ntawm HEMC

Kev yooj yim ntawm kev tsim kho: Kev siv HEMC tuaj yeem txhim kho kev tsim kho ntawm cov nplais pobzeb adhesives, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam loj paving thiab complex ib puag ncig, ua rau txoj kev tsim kho smoother.

Durability: Txij li HEMC tuaj yeem txhim kho cov dej tuav thiab kev sib txuas lub zog ntawm cov nplaum, cov nplais pobzeb txheej tom qab kev tsim kho yog ruaj khov thiab ruaj khov.

Environmental adaptability: Nyob rau hauv qhov sib txawv ntawm qhov kub thiab av noo, HEMC tuaj yeem tswj tau qhov kev tsim kho ntawm cov nplaum thiab hloov mus rau kev hloov pauv huab cua hauv cheeb tsam sib txawv.

Nqi-Effectiveness: Txawm hais tias tus nqi ntawm HEMC yog siab dua, nws cov kev txhim kho tseem ceeb tuaj yeem txo qhov kev xav tau ntawm kev tsim kho thiab kev saib xyuas, yog li txo tus nqi tag nrho.

5. Txoj kev loj hlob zeem muag ntawm HEMC nyob rau hauv ceramic pobzeb nplaum daim ntaub ntawv

Nrog kev nce qib txuas ntxiv ntawm cov cuab yeej siv hauv tsev, HEMC yuav siv dav dua hauv cov nplais pobzeb nplaum. Nyob rau hauv lub neej yav tom ntej, raws li cov kev cai rau kev tiv thaiv ib puag ncig kev ua tau zoo thiab kev tsim kho efficiency nce, HEMC cov cuab yeej technology thiab cov txheej txheem ntau lawm yuav tsum tau txhim kho kom tau raws li cov kev xav tau ntawm kev ua tau zoo, kev siv hluav taws xob tsawg thiab kev tiv thaiv ib puag ncig ntsuab. Piv txwv li, cov qauv molecular ntawm HEMC tuaj yeem ua kom zoo dua ntxiv kom ua tiav cov dej tuav thiab kev sib raug zoo, thiab txawm tias cov ntaub ntawv HEMC tshwj xeeb tuaj yeem tsim kho uas tuaj yeem hloov kho rau cov substrates tshwj xeeb lossis cov av noo thiab qhov kub thiab txias.

Raws li cov khoom tseem ceeb hauv cov nplais nplaum, HEMC txhim kho kev ua tau zoo ntawm cov nplais nplaum los ntawm kev txhim kho cov dej tuav, kev sib khi lub zog thiab kev tsim kho. Kev kho kom tsim nyog ntawm qhov ntau npaum li cas ntawm HEMC tuaj yeem txhim kho kev ua haujlwm ntev thiab kev sib koom ua ke ntawm cov nplais pobzeb nplaum, kom ntseeg tau qhov zoo thiab ua haujlwm ntawm kev tsim kho vaj tsev. Nyob rau hauv lub neej yav tom ntej, nrog rau txoj kev loj hlob ntawm technology thiab kev hloov nyob rau hauv kev ua lag luam kev xav tau, HEMC yuav siv ntau lug siv nyob rau hauv ceramic pobzeb adhesives, muab ntau npaum thiab ib puag ncig tus phooj ywg kev daws teeb meem rau kev tsim kho kev lag luam.
