Kev Taw Qhia Txog Qib Muaj HPMC

1. Dab tsi yog Qib Industrial HPMC

Qib Kev Lag LuamHPMC (Hydroxypropyl Methylcellulose)yog ib qho non-ionic cellulose ether derivative, feem ntau yog nyob rau hauv daim ntawv ntawm cov hmoov dawb los yog me ntsis daj. Nws yog ua los ntawm cov paj rwb ntuj linter fibers los ntawm kev kho alkali thiab ib tug series ntawm cov tshuaj tshuag (xws li etherification), thiab muaj biocompatibility zoo thiab tshuaj stability. Vim nws cov khoom tshwj xeeb lub cev thiab tshuaj, HPMC yog dav siv nyob rau hauv ntau yam kev lag luam xws li kev tsim kho, coatings, ceramics, thiab cov tshuaj ua liaj ua teb.

2. Kev Ua Tau Zoo ntawm Qib Industrial HPMC

Ua kom tuab

HPMC muaj peev xwm ua kom tuab zoo heev thiab tuaj yeem ua rau kom cov viscosity ntawm cov kua dej nce ntxiv, yog li txhim kho kev tsim kho, slurry thiab txhuam cov khoom ntawm cov khoom.

Kev Khaws Dej

Hauv cov ntawv thov xws li mortar thiab putty, HPMC tuaj yeem txhim kho qhov khaws cia dej ntawm cov khoom, tiv thaiv kev poob dej sai, txuas ntxiv lub sijhawm ua haujlwm, thiab txhim kho qhov ceev thiab kev nplaum ntawm cov khoom tiav.

Kev Tsim Yeeb Yam

HPMC tuaj yeem tsim ib zaj duab xis tawv thiab pob tshab rau ntawm qhov chaw, muab cov khoom zoo tiv thaiv thiab ci ntsa iab.

Kev sib kis thiab emulsification

HPMC muaj kev sib kis zoo hauv dej thiab siv tau ua emulsifier los tswj lub kaw lus thiab txhim kho qhov sib xws thiab ruaj khov ntawm cov mis.

Kev ua kom sov

Cov kua dej HPMC yuav tsim cov gel thaum cua sov mus rau qee qhov kub. Cov khoom siv gel no muaj txiaj ntsig zoo rau qee qhov kev siv tshwj xeeb.

3. Cov chaw thov tseem ceeb ntawm qib kev lag luam HPMC

Kev lag luam tsim kho

Cov tshuaj khib qhuav sib xyaw (xws li cov nplaum pobzeb, cov tshuaj khib plaster, cov tshuaj khib tus kheej): HPMC tuaj yeem txhim kho qhov tuav dej, kev nplaum thiab kev ua haujlwm ntawm cov tshuaj khib.

Hmoov Putty: Txhim kho qhov kev xav ntawm kev tsim kho, tiv thaiv kev tawg thiab npuas, thiab txhim kho qhov zoo ntawm cov khoom tiav.

Lub kaw lus rwb thaiv tsev sab nraud (EIFS): Txhim kho qhov lo thiab kev ywj pheej ntawm cov mortar thiab txuas ntxiv kev ruaj khov.

Kev lag luam pleev xim

HPMC yog siv los ua cov khoom siv thickener, stabilizer thiab zaj duab xis ua ntej los txhim kho kev ua haujlwm tiv thaiv kev sagging, tuaj yeem qhib kev ruaj khov thiab zaj duab xis sib xws ntawm cov txheej.

Kev lag luam ceramic

Hauv kev tsim cov khoom siv ceramic, HPMC ua lub luag haujlwm hauv kev khaws cia dej, lubrication, molding, thiab lwm yam, pab txhim kho qhov ceev thiab tawg tsis kam ntawm cov khoom.

Cov khoom siv tshuaj lom neeg txhua hnub

Ntxiv HPMC rau hauv cov tshuaj ntxuav thiab cov tshuaj ntxuav tes tuaj yeem ua rau cov khoom sib xws, ua rau cov ua npuas ncauj zoo dua thiab ruaj khov dua, thiab txhim kho kev ruaj khov ntawm cov mis.

Kev khawb roj

Ua ib qho tshuaj ntxiv rau cov kua dej drilling, HPMC tuaj yeem kho qhov rheology ntawm cov kua dej drilling, tiv thaiv kom tsis txhob muaj dej ntws hauv phab ntsa, thiab txhim kho kev ua haujlwm ntawm drilling.

4. Yuav siv HPMC qib kev lag luam li cas

Feem ntau, HPMC yuav tsum tau muab faib rau hauv dej txias kom tsim tau ib qho kev daws teeb meem kom muab kev ua si tag nrho rau nws cov kev ua tau zoo. Cov kauj ruam siv feem ntau yog raws li nram no:

Maj mam tsuag HPMC rau hauv dej txias uas tau do kom tsis txhob sib xyaw ua ke.

Txuas ntxiv do kom txog thaum pib dispersion.

Sawv ntsug rau ib lub sijhawm (feem ntau ntau tshaj 2 teev) kom hydrate tag nrho thiab yaj cov cellulose.

Yog tias tsim nyog, do kom zoo kom txog thaum cov kua pob tshab lossis pob tshab sib xyaw ua ke.

Hauv cov ntawv thov kev lag luam tiag tiag, qhov ntau ntawm HPMC ntxiv qee zaum raug kho raws li qhov xav tau, feem ntau tswj hwm ntawm 0.1% thiab 2.0%, thiab qhov sib piv tshwj xeeb nyob ntawm lub cev mis thiab qhov cuam tshuam xav tau.

5. Kev tswj xyuas zoo thiab kev xaiv siv

Qib kev lag luam HPMC muaj cov lus qhia sib txawv ntawm viscosity (xws li 400 mPa.s, 15000 mPa.s, thiab lwm yam) thiab qib hloov pauv (piv txwv li qib hloov pauv ntawm hydroxypropyl thiab methyl) raws li cov kev xav tau ntawm daim ntawv thov sib txawv. Kev xaiv tus qauv zoo muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ntawm cov khoom. Cov khoom sim ib txwm muaj xws li:

Viscosity (2% kua ntawm chav tsev kub)

Cov dej noo

Cov ntsiab lus ntawm tshauv

Cov ntsiab lus ntawm Methoxy thiab hydroxypropyl

Tus nqi pH (1% kua dej)

Cov qib kev lag luam zoo HPMC yuav tsum muaj cov yam ntxwv ntawm cov tshauv tsawg, kev sib kis zoo, viscosity ruaj khov, thiab kev yaj sai.

6. Kev khaws cia thiab ntim khoom

HPMC yuav tsum khaws cia rau hauv qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo, tsis txhob cia kub thiab txias, av noo thiab tshav ntuj ntau dhau kom tiv thaiv kev nqus dej noo, kev sib sau ua ke lossis kev hloov pauv ntawm kev ua haujlwm. Feem ntau nws ntim rau hauv cov hnab ntawv sib xyaw ua ke ntau txheej uas muaj cov hnab polyethylene zaj duab xis. Cov lus qhia ntim khoom txheem yog 25 kg/hnab, uas kuj tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.

Qib kev lag luam HPMCUa lub luag haujlwm tseem ceeb hauv ntau qhov chaw lag luam nrog nws cov khoom zoo heev thiab tshuaj lom neeg. Nrog rau kev nce ntxiv ntawm cov ntaub ntawv tsim kho ntsuab, cov tshuaj pleev ib puag ncig thiab cov ntaub ntawv sib xyaw ua ke zoo, qhov kev thov rau HPMC zoo kuj tseem loj hlob. Yav tom ntej, nrog rau kev ua kom zoo dua ntawm cov txheej txheem tsim khoom thiab kev nthuav dav ntawm cov teb thov, HPMC qib kev lag luam yuav qhia txog kev cia siab dav dua.
