Kev Tsim Kho Qib HPMC Self-leveling Compound

HPMC, los yog Hydroxypropyl Methylcellulose, yog ib qho cellulose ether uas tau siv dav hauv kev tsim kho kev lag luam.Nws yog feem ntau siv los ua ib qho additive nyob rau hauv nws tus kheej-leveling tebchaw, uas yog cov ntaub ntawv siv rau theem tsis sib xws hauv pem teb los yog tsim ib tug du nto rau lwm yam ntaub ntawv flooring.

Self-leveling tebchaw feem ntau yog siv rau hauv kev tsim kho tej yaam num mus rau theem pem teb uas tsis sib xws los yog muaj tsawg me ntsis.Cov tebchaw no feem ntau yog tsim los ntawm kev sib xyaw ntawm cov cement, xuab zeb, thiab lwm yam ntaub ntawv, thiab sib tov nrog dej los tsim cov kua dej.Thaum poured rau hauv pem teb, tus kheej-leveling compound ntws los tsim ib tug du, theem nto.

HPMC feem ntau tau ntxiv rau qhov sib xyaw ua ke ntawm tus kheej los txhim kho lawv cov kev ua tau zoo.Tshwj xeeb, nws pab txhim kho kev ua haujlwm ntawm qhov sib xyaw ua ke, ua kom yooj yim rau cov ncuav thiab kis tusyees.Nws kuj tseem tuaj yeem pab txo qis qis thiab tawg thaum lub sij hawm ziab, thiab tuaj yeem txhim kho lub zog ntawm kev sib txuas ntawm cov khoom sib xyaw thiab cov hauv qab substrate.

Kev tsim kho qib HPMC yog hom HPMC tshwj xeeb uas tsim los siv rau hauv kev tsim kho.Nws yog feem ntau siv nyob rau hauv tus kheej-leveling tebchaw, nrog rau lwm yam khoom siv hauv tsev xws li mortars, grouts, thiab stuccos.

Cov khoom tshwj xeeb ntawm kev tsim kho qib HPMC tuaj yeem sib txawv nyob ntawm cov khoom siv thiab cov chaw tsim khoom, tab sis feem ntau, nws muaj cov yam ntxwv hauv qab no:

Kev tuav dej siab: HPMC yog cov khoom siv hydrophilic, uas txhais tau hais tias nws muaj kev sib raug zoo rau dej.Cov cuab yeej no pab txhim kho kev ua haujlwm ntawm tus kheej-leveling compounds, raws li nws yuav pab kom cov sib tov ntub thiab yooj yim rau kis.

Kev muaj peev xwm ua yeeb yaj kiab zoo: HPMC tuaj yeem tsim cov yeeb yaj kiab nyias ntawm qhov chaw ntawm tus kheej-leveling compound thaum nws qhuav, uas yuav pab txhim kho nws lub zog thiab ua haujlwm ntev.

Txhim kho adhesion: HPMC tuaj yeem txhim kho qhov adhesion ntawm tus kheej-leveling compound rau hauv qab substrate, pab tsim kom muaj zog, ruaj khov dua.

Txo cov shrinkage thiab cracking: HPMC tuaj yeem pab txo qis qis thiab tawg uas tshwm sim thaum lub sij hawm ziab, uas tuaj yeem ua rau lub ntsej muag ntau dua thiab du.

Tsis muaj tshuaj lom thiab ib puag ncig tus phooj ywg: HPMC yog cov khoom tsis muaj tshuaj lom, ib puag ncig tus phooj ywg uas muaj kev nyab xeeb rau kev siv hauv kev tsim kho.

Thaum siv cov tshuaj tiv thaiv tus kheej uas muaj qib HPMC, nws yog ib qho tseem ceeb kom ua raws li cov neeg tsim khoom cov lus qhia ua tib zoo.Cov sib tov yuav tsum tau npaj raws li qhov pom zoo ntawm cov dej-rau-hmoov piv, thiab yuav tsum tau muab sib xyaw kom huv si kom paub meej tias HPMC tau sib npaug sib npaug thoob plaws qhov sib xyaw.

Thaum tus kheej-leveling compound tau muab tso rau hauv pem teb, nws yuav tsum tau kis nrog ib tug trowel los yog lwm yam cuab yeej los tsim ib tug txawm nto.Nws yog ib qho tseem ceeb kom ua hauj lwm sai sai, vim hais tias lub compound yuav pib teem nyob rau hauv ib tug luv luv lub sij hawm.

Tom qab qhov sib xyaw ua ke tau sib kis, nws yuav tsum tau tso kom qhuav rau lub sijhawm pom zoo ua ntej cov khoom siv hauv pem teb ntxiv.Qhov no yuav pab xyuas kom meej tias qhov chaw tau kho tau zoo thiab npaj rau kev siv.

Zuag qhia tag nrho, kev tsim kho qib HPMC yog cov khoom siv tseem ceeb hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev txhim kho ntawm tus kheej-leveling compounds.Nws cov khoom tshwj xeeb pab txhim kho kev ua haujlwm ntawm cov ntaub ntawv no, ua rau lawv yooj yim rau kev ua haujlwm nrog thiab ruaj khov dua lub sijhawm.Los ntawm kev siv tus kheej-leveling compounds uas muaj HPMC, cov kws tshaj lij kev tsim kho tuaj yeem tsim du, theem saum npoo uas haum rau ntau yam khoom siv hauv pem teb.
