Cov txiaj ntsig ntawm Kev Siv HPMC rau Tus Kheej Qib mortar

Tus kheej-theem mortar (SLM) yog cov khoom siv qis-viscous cement pem teb uas tuaj yeem siv rau hauv pem teb los tsim cov npoo du thiab seamless. Cov khoom siv no yog siv dav hauv kev tsim kho, xws li kev lag luam thiab kev lag luam hauv tsev, cov tsev nyob thiab chaw ua haujlwm. Nws kuj yog siv los kho thiab rov ua dua cov flooring uas twb muaj lawm. Ib qho tseem ceeb tshaj plaws ntawm SLM yog hydroxypropyl methylcellulose (HPMC). HPMC yog cellulose ether. Nws yog siv los ua thickener, nplaum, emulsifier, stabilizer thiab ncua kev kawm ntawv nyob rau hauv ntau yam kev siv nyob rau hauv kev tsim kho kev lag luam. Nov yog qee qhov txiaj ntsig rau kev siv HPMC rau tus kheej-theem mortar.

Txhim kho kev ua tau zoo

HPMC yog cov khoom siv ntau yam polymer uas tuaj yeem siv dav hauv cov ntaub ntawv cement-based flooring. Nws txhim kho qhov ua tau zoo ntawm cov tshuaj khib nyiab los ntawm kev txhim kho cov peev txheej ntawm cov khoom sib tov. Qhov no txhais tau hais tias SLM tuaj yeem ua tau rau lub sijhawm ntev dua, kom tus neeg cog lus muaj sijhawm ntau los siv nws ua ntej cov khoom siv. HPMC kuj ua raws li cov roj nplua nyeem, uas txhim kho kev khiav hauj lwm ntawm SLM, uas yog ib qho yooj yim mus siv thiab faib tusyees.

Zoo heev processability reservation

Lwm qhov zoo ntawm kev siv HPMC nyob rau hauv lub mortar ntawm tus kheej-theem yog nws superior processability tuav cov yam ntxwv. SLM tus tsim yog tus kheej-theem, uas txhais tau hais tias nws muaj peev xwm sib npaug ntawm qhov chaw kho. Txawm li cas los xij, txoj kev kho yuav raug cuam tshuam los ntawm ntau yam, xws li qhov kub thiab txias ntawm ib puag ncig ib puag ncig, theem ntawm cov av noo, thiab lub thickness ntawm txheej. HPMC pab txo qis qhov cuam tshuam ntawm cov xwm txheej no los ntawm kev tswj xyuas kev ua tiav ntawm cov xwm txheej no thaum sib xyaw. Yog li ntawd, lub hauv pem teb tiav lawm muaj ib tug du nto.

Txhim kho kev txuag dej

Dej plays lub luag haujlwm tseem ceeb hauv kev txhim kho ntawm tus kheej-theem mortar. Cov dej tsawg dhau tuaj yeem ua rau cov khaubncaws sab nraud povtseg thiab tsis yooj yim, thiab cov dej ntau dhau tuaj yeem ua rau cov dej sib tov sib xyaw thiab tawg nrog dryness. HPMC pab txhim kho kev tuav lub peev xwm ntawm SLM, yog li txo qhov kev pheej hmoo ntawm kev cog lus thiab tawg. Qhov no tuaj yeem ua kom ntseeg tau tias hauv pem teb muaj cov yam ntxwv zoo sib xws thiab txhim kho durability.

Zoo adhesion

HPMC kuj tseem txhim kho cov yam ntxwv ntawm kev sib txuas ntawm nws tus kheej mortar, yog li txhim kho nws cov adhesion rau ntau qhov chaw. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev txhim kho hauv pem teb uas twb muaj lawm. Nyob rau hauv pem teb uas twb muaj lawm, SLM yuav tsum tau khaws cia tag nrho nrog cov qub nto los tsim seamless decorations. HPMC ua raws li kev sib khi los pab cov cement particles lo rau lawv ua ke thiab khi rau saum npoo. Qhov no ua rau hauv pem teb muaj kev hnav zoo heev, txhim kho durability, thiab zoo tiv thaiv kev cuam tshuam thiab rupture.

Cov yam ntxwv siab kawg

Qhov ntws ntawm tus kheej-theem mortar yog qhov tseem ceeb kom ua tiav qhov du lossis txawm nto. HPMC txhim kho kev khiav tsheb ntawm SLM, ua kom yooj yim rau kev sib kis sib npaug ntawm qhov chaw. Qhov no txo ​​qhov kev thov rau ntau hneev thiab xub, uas tuaj yeem ua rau tsis zoo ntawm qhov tsis sib xws thiab cov khoom siv tsis zoo. HPMC tseem ua kom ntseeg tau tias SLM muaj cov yam ntxwv zoo kab rov tav, kom hauv pem teb muaj qhov sib luag, zoo ib yam thiab zoo ib yam.

Zoo drooping kuj

Thaum nws siv rau saum npoo, SLM tuaj yeem sag thiab tawm ntawm qhov tsis sib xws. HPMC txhim kho qhov tsis kam ntawm qhov sib tov los ntawm kev ua kom nws tswj tau nws cov duab thiab sib xws thaum siv. Qhov no txhais tau hais tias tus neeg cog lus tuaj yeem thov cov txheej txheem SLM tuab dua yam tsis muaj kev txhawj xeeb txog kev poob. Qhov kawg tshwm sim yog tias qhov saum npoo tau zoo heev adhesion thiab du thiab txawm tias zoo nkauj.

nyob rau hauv xaus

Kev siv hydroxypropyl methyl cellulose (HPMC) muaj ntau yam txiaj ntsig rau kev tsim tus kheej-theem mortar. Nws txhim kho cov txheej txheem ntawm SLM, txhim kho qib dej, txhim kho kev sib koom ua ke, txhim kho cov dej ntws, txhim kho SAG tsis kam, thiab xyuas kom meej tias pem teb tiav yog du, zoo ib yam. Cov txiaj ntsig ntawm kev siv HPMC rau tus kheej-theem mortars ua rau nws yog cov khoom siv zoo tshaj plaws ntawm ntau yam kev lag luam, kev lag luam, thaj chaw, thiab cov haujlwm hauv tsev.
