HPMC siv hauv kev tsim kho

HydroxyPropy cellulose (HPMC) yog ib hom neeg ntxiv rau hauv kev tsim kho hauv kev ua haujlwm rau ntau yam kev siv. Nws yog qhov muaj nuj nqis rau nws cov khoom siv rheological, kev ua kom dej rov qab los, thiab kev txhawb nqa cov yam ntxwv txhawb nqa. Nov yog qee qhov tseem ceeb siv HPMC hauv kev tsim kho:

1. Mortars thiab cov khoom siv xas

1.1 Cov neeg sawv cev tuab

HPMC pab raws li tus neeg sawv cev ua tuab rau hauv cov kab kab. Nws pab tswj lub viscosity ntawm cov sib tov, pub rau kev ua haujlwm zoo thaum lub ntaub ntawv thov.

1.2 Dej Tuav

Ib qho ntawm cov luag haujlwm tseem ceeb ntawm HPMC hauv Mortars yog dej khaws cia. Nws tiv thaiv ceev dej evaporation, kom ntseeg tau tias lub tshuaj khib tseem ua haujlwm rau lub sijhawm ncua thiab txhim kho cov nyiaj sib txuas nrog substrates.

1.3 txhim kho adhesion

HPMC txhim kho cov nplaum ntawm cov khoom noj qabent-based rau ntau qhov chaw, muab kev sib raug zoo ntawm cov tshuaj khib thiab substrates.

2. Pobzeb Ntawv Qhia

2.1 Cov dej ua ke

Nyob rau hauv cov nplais nplaum tsim, HPMC txhawb cov dej ua ke, tiv thaiv cov nplaum los ntawm kev ziab tawm sai thiab tso cai rau kev tso cai ua kom tsim nyog.

2.2 Rheology tswj

HPMC ua raws li kev hloov kho rheology, tswj hwm qhov ntws thiab xwm yeem ntawm cov nplais nplaum kom ntseeg tau yooj yim.

2.3 Adhesion nce qib

Cov nplaum muaj zog ntawm cov pobzeb cov nplaum tau txhim kho nrog kev sib ntxiv ntawm HPMC, ua kom muaj kev sib txuas lus ruaj khov ntawm cov nplaum thiab cov vuas.

3. Cov Plasters thiab Cov Khoom Siv

3.1 Kev Ua Haujlwm Txiaj Ntsig

Hauv plaster thiab render formulation, HPMC txhim kho lub zog ua haujlwm, ua rau nws siv tau yooj yim rau cov khoom kom yooj yim rau hauv cov chaw.

3.2 Dej Tuav Haujlwm

HPMC pab txhawb dej nyob hauv Plasters thiab ua kom tiv thaiv kom nrawm thiab ua rau lub sijhawm kom txaus rau lub sijhawm tsim nyog.

3.3 Sag Kuj

Lub zog rheological ntawm HPMC pab tiv thaiv sagging lossis slumping ntawm plasters thiab renders thaum lub ntawv thov, kev ceev xwm txheej tuab.

4. QHOB

4.1 Rheology tswj

Hauv cov pob zeb ua qauv, HPMC ua raws li kev hloov kho rheology, muaj kev cuam tshuam nrog cov khoom siv ntawm cov pob zeb ua ke rau kev ua haujlwm zoo dua.

4.2 Dej txo

HPMC tuaj yeem pab txhawb rau kev txo qis hauv cov pob zeb sib xyaw, tso cai rau kev txhim kho lub zog thiab lub sijhawm thaum muaj kev tswj hwm.

5. Kev ua tus kheej sib txuas

5.1 ntws tswj

Nyob rau hauv tus kheej-qib sib txuas, HPMC pab tswj cov khoom ntws, tiv thaiv kev sib hais haum thiab ua kom muaj kev ua kom du, theem.

5.2 Dej Tuav

Cov dej rov qab los ntawm HPMC muaj txiaj ntsig zoo nyob rau hauv tus kheej-compounds, kom muaj kev sib xyaw ua haujlwm tseem ua haujlwm ntev.

6. Kev txiav txim siab thiab ceev faj

6.1 noj

Qhov ntau npaum ntawm HPMC yuav tsum tau ua tib zoo tswj kom ua tiav cov khoom uas xav tau yam tsis muaj kev cuam tshuam nrog lwm tus yam ntxwv ntawm cov khoom siv kev tsim kho.

6.2 kev sib raug

HPMC yuav tsum sib haum nrog lwm cov khoom hauv kev tsim kho. Kev ntsuas kev sib raug zoo yog qhov tseem ceeb kom zam cov teeb meem xws li txo cov txiaj ntsig lossis kev hloov pauv hauv cov khoom siv khoom.

6.3 Kev cuam tshuam ib puag ncig

Kev txiav txim siab yuav tsum tau muab rau ib puag ncig kev cuam tshuam ntawm kev tsim cov khoom siv, suav nrog HPMC. Kev ruaj khov thiab cov kev xaiv hauv eco-phooj ywg tau nce tseem ceeb hauv kev tsim kho kev tsim kho.

7. Xaus

HydroxyPropy cellulose yog ib qho tseem ceeb ntxiv rau hauv kev tsim kho, cov nplaum, cov nplaum, ua pob zeb, thiab kev sib txuas ua ke. Nws cov khoom ntau yam ua rau nws yog qhov tseem ceeb hauv kev txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov ntaub ntawv tsim kho. Ua tib zoo xav txog kev siv tshuaj, kev sib raug zoo, thiab ib puag ncig thiab cov kev pab hpmc maximizes nws cov txiaj ntsig maximizes nws cov txiaj ntsig maximizes nws cov txiaj ntsig zoo hauv cov kev siv kev siv.
