Cov txiaj ntsig ntawm kev siv HPMC cov qhab nia nyob hauv cov ntaub ntawv hauv tsev?

HPMC (HydroxyPropyyl methylulose) yog ib qho kev siv ntau yam ntxiv tau siv nyob rau hauv cov ntaub ntawv hauv tsev, thiab nws cov qib tau sib txawv raws li kev siv sib txawv thiab kev ua tau zoo. Lub ntsiab zoo ntawm kev siv HPMC hauv kev tsim kho HPMC hauv kev tsim kho kev tsim kho suav nrog txhim kho kev ua haujlwm zoo, txhim kho cov khoom siv zoo thiab ua kom zoo dua qub.

1. Txhim kho kev tsim kho kev tsim kho
HPMC muaj cov dej ua kom zoo heev, cov dej tuav thiab lubrication cov khoom, uas ua lub luag haujlwm tseem ceeb hauv kev tsim kho cov ntaub ntawv hauv tsev:

Txhim khu kev ua haujlwm ntawm kev ua haujlwm: HPMC hloov kho xwm yeem thiab viscosity ntawm cug, ua kom nws yooj yim thov thiab cov duab thaum kev tsim kho.

Tiv thaiv kev nruj thiab cais: hauv cov ntawv thov ntub dej, HPMC tuaj yeem txhim kho qhov ruaj khov ntawm cov ntaub ntawv thiab xyuas kom meej.

Lub sijhawm qhib qhib lub sijhawm ntev: thaum kev tsim kho, HPMC tuaj yeem hloov lub sijhawm qhib, cov khoom mortars, cov ntaub ntawv, yooj yim kho thiab tsim kho kom zoo.

2. Txhim Kho Cov Dej Ua Haujlwm
HPMC muaj lub peev xwm retentive heev, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub kub:

Lub sijhawm ntev ntawm cov cement lossis Gypsum: Kev tuav dej yuav pab txo cov kab nrib pleb tshwm sim los ntawm kev ua haujlwm thaum ntxov thiab txhim kho kho cov nyhuv.
Txhim kho substrate bonding: noo noo nyob rau hauv cov khoom tuaj yeem yog fayly faib, txhim kho cov nplaum ntawm lub cug rau ntawm substrate.
Txuag dej: los ntawm kev txo dej poob, qhov xav tau ntawm kev siv dej ntxiv ntawm kev siv khoom yog txo qis.

3. Txhim kho kev tawm tsam kev tawm tsam
HPMC muab cov duab kos duab kos duab thiab cov neeg Mortars ua kom zoo dua:

On ntsug chaw tsim chaw (xws li phab ntsa hlau), nws tuaj yeem txo cov khoom siv uas swb lossis sagging thiab xyuas kom zoo nkauj tuab ntawm txheej.
Rau tuab tuab txheej txheej (xws li cov nplais nplaum), ua kom zoo ntawm HPMC cov qhab nia tuaj yeem tiv thaiv txheej uas tau poob los ntawm kev sib tsoo.

4. Txhim kho cov khoom siv ruaj khov
Kev siv cov qib siab HPMC tuaj yeem txhim kho cov khoom siv hauv tsev:

Fanze-thaw voj voog tsis kam: HPMC txhim kho cov khoom siv lub fria frostance thiab tawg tsis kam, tshwj xeeb tshaj yog rau cov cheeb tsam txias.
Tshuaj lom neeg thiab UV Kuj: hauv sab nrauv phab ntsa tsis muaj phab ntsa thiab cov tsho tiv no, hpmc txhim kho nws cov antioxidant thiab corrosion tsis kam thiab nthuav nws lub neej kev pabcuam.

5. Hloov kho kom tau raws li cov kev xav tau sib txawv
Cov qhab nia HPMC (piv txwv li viscosity, qib hloov chaw) tuaj yeem hloov kho raws li cov ntawv siv sib txawv:

Pobzeb nplaum: tsis muaj viscosity HPMC pab txhawb kev nrawm nrawm, thaum lub siab viscosity pab txhim kho kev ua haujlwm.
Putty hmoov: du txheej thiab cov nplaim qab heev tau tiav los ntawm kev visccosity HPMC.
Kev Ntsuas Tus Kheej Theem: HPMC Tswj Filmity kom ntseeg tau cov kev coj ua thiab kev tsim kho.

6. Ntsuab thiab Zog-Txuag
HPMC yog qhov tsis muaj tshuaj lom thiab tsis muaj zog ntsuab thiab ib puag ncig cov khoom siv uas txo cov tshuaj phem rau kev tsim kho. Ib qho ntxiv, los ntawm kev txhim kho cov khoom siv tau thiab txuag dej, kev tsim kho lub zog ntxiv tuaj yeem ua tiav.

Hauv cov ntaub ntawv hauv tsev, kev siv cov qib tsim nyog ntawm HPMC tsis tuaj yeem txhim kho kev tsim kho cov khoom siv thiab cov khoom siv zoo thiab muaj kev ruaj khov ntawm cov khoom siv tsev. Xaiv cov qib HPMC uas tsim nyog raws li cov kev xav tau tuaj yeem ua tiav kev ua tau zoo thaum txo cov nqi thiab kev nyuaj. Cov yam ntxwv no ua HPMC qhov tsis tseem ceeb thiab cov khoom muaj nyob hauv cov qauv ntawm cov ntaub ntawv tsev tshiab niaj hnub no.
