Lub luag haujlwm ntawm hydroxypropyl methylcellulose hauv mortar

Hydroxypropylmethylcellulose

Ntau tshaj 95% ntawm qib kev tsim khohydroxypropyl methylcellulosesiv rau hauv cov hmoov putty. Nws lub luag haujlwm yog thickening, dej khaws cia thiab kev tsim kho. Kev ua haujlwm khaws cia dej ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim qhuav sai dhau tom qab thov, txhim kho lub zog tom qab hardening, lub luag haujlwm tseem ceeb yog dej khaws cia, thickening, thiab anti-sagging teebmeem. Nws tuaj yeem siv ua cov nplaum hauv plaster, gypsum, putty hmoov lossis lwm yam khoom siv hauv tsev kom txhim kho kev nthuav dav thiab ntev lub sijhawm ua haujlwm; xws li cov vuas ceramic, marble, plastics Kho kom zoo nkauj: Raws li cov nplaum enhancer, nws kuj tuaj yeem txo qhov ntau ntawm cov cement; rau cov tshuaj tiv thaiv kab nrib pleb, ntxiv qee cov polypropylene anti-crack fiber (PP fiber) hauv qhov ntau thiab tsawg, yog li lawv muaj nyob rau hauv daim ntawv ntawm barbs hauv cov tshuaj mortar, yog li ua tiav cov nyhuv tiv thaiv kab nrib pleb. HPMC tsuas yog ua lub luag haujlwm ntawm dej khaws cia, thickening thiab anti-sagging.

1. Kev tsim kho mortar plastering mortar

Kev khaws dej ntau tuaj yeem ua rau cov cement muaj dej txaus, ua rau lub zog sib txuas ntau ntxiv, thiab tib lub sijhawm, nws tuaj yeem ua rau lub zog tensile thiab lub zog shear ntau ntxiv, txhim kho cov txiaj ntsig ntawm kev tsim kho thiab txhim kho kev ua haujlwm zoo.

2. Cov tshuaj pleev dej tsis haum

Hauv putty, hydroxypropyl methylcellulose cellulose ether feem ntau ua lub luag haujlwm ntawm kev khaws dej, kev sib txuas thiab lubrication, zam kev tawg thiab dehydration los ntawm kev poob dej ntau dhau, thiab tib lub sijhawm txhim kho qhov adhesion ntawm putty thiab txo qhov sag thaum lub sijhawm tsim kho, yog li ntawd kev tsim kho yog du.

3. Cov koob plaster plaster

Ntawm cov khoom lag luam gypsum series, hydroxypropyl methylcellulose cellulose ether feem ntau ua lub luag haujlwm ntawm kev khaws dej thiab lubrication, thiab tib lub sijhawm muaj qee qhov cuam tshuam retarding, uas daws cov teeb meem ntawm lub nruas tawg thiab pib lub zog tsis ua haujlwm thaum lub sijhawm tsim kho, thiab tuaj yeem txuas ntxiv lub sijhawm ua haujlwm.

4. Tus neeg sawv cev sib txuas lus

Nws yog siv los ua cov khoom siv tuab, uas tuaj yeem txhim kho lub zog tensile thiab shear zog, txhim kho qhov txheej txheem saum npoo, txhim kho qhov adhesion thiab bonding zog.

5. Cov tshuaj nplaum rwb thaiv tsev phab ntsa sab nraud

Hauv cov khoom siv no, hydroxypropyl methylcellulose cellulose ether feem ntau ua lub luag haujlwm ntawm kev sib txuas thiab ua kom lub zog ntxiv, ua rau nws yooj yim dua rau txheej cov mortar thiab txhim kho kev ua haujlwm zoo. Ua kom lub sijhawm ua haujlwm ntawm mortar nce ntxiv, txhim kho kev ntsws thiab kev tawg tsis kam, txhim kho qhov zoo ntawm qhov chaw, thiab ua kom lub zog sib txuas ntxiv.

6. Cov nplaum rau pobzeb

Qhov dej khaws cia siab tsis tas yuav tsum tau ntub lossis ntub cov vuas thiab lub hauv paus ua ntej, uas tuaj yeem txhim kho lawv lub zog sib txuas. Cov slurry tuaj yeem muaj lub sijhawm tsim kho ntev, zoo thiab sib xws, thiab yooj yim rau kev tsim kho. Nws kuj muaj kev tiv thaiv dej noo zoo.

7, tus neeg sawv cev caulking, tus neeg sawv cev taw qhia

Qhov ntxiv ntawmhydroxypropyl methylcellulose cellulose etherua rau nws muaj kev sib txuas zoo ntawm ntug, qis shrinkage thiab siab hnav tsis kam, uas tiv thaiv cov khoom siv los ntawm kev puas tsuaj kho tshuab thiab zam kev puas tsuaj los ntawm kev nkag mus rau tag nrho lub tsev. Kev cuam tshuam.
