Yuav ua li cas kom qhuav cov nplais nplaum nplaum nrog HPMC?

Cov pobzeb nplaum yog siv dav hauv kev tsim kho kom ruaj ntseg cov vuas rau thaj chaw xws li phab ntsa thiab hauv pem teb. Nws muab lub zog adhesion ntawm pobzeb thiab saum npoo, txo qhov kev pheej hmoo ntawm pobzeb hloov. Feem ntau hais lus, pobzeb nplaum muaj cov cement, xuab zeb, additives thiab polymers.

HPMC (Hydroxypropyl Methyl Cellulose) yog ib qho tseem ceeb ntxiv uas tuaj yeem nqa tau ntau yam txiaj ntsig rau cov nplais nplaum. Nws tuaj yeem txhim kho cov dej tuav, kev ua haujlwm, kev ua haujlwm tsis zoo thiab lwm yam khoom ntawm cov nplaum, thiab txhim kho nws lub zog sib txuas. HPMC tau siv dav hauv cov pobzeb nplaum vim nws cov dej tuav tau zoo, uas ua kom cov nplaum siv tshiab tseem ntub los txhawb kev tsim cov ntawv cog lus zoo.

Hauv tsab xov xwm no, peb yuav tham txog cov kauj ruam los ua kom qhuav cov nplais nplaum nplaum nrog HPMC. Nws yog ib qho tseem ceeb uas yuav tau ua raws li cov txheej txheem kom tau raws li qhov xav tau thiab cov khoom ntawm cov nplaum.

Kauj Ruam 1: Sau cov khoom tsim nyog

Ua ntej pib txheej txheem, xyuas kom tseeb tias koj muaj tag nrho cov ntaub ntawv koj xav tau los ua cov nplaum nplaum. Lawv suav nrog:

- HPMC hmoov

- Portland cement

- xuab zeb

- dej

- ib lub thawv sib tov

- blend tool

Kauj Ruam 2: Npaj lub nkoj sib tov

Xaiv lub thawv sib tov loj txaus los tuav lub ntim ntawm cov ntaub ntawv siv los ua cov nplaum. Xyuas kom lub thawv huv huv, qhuav thiab tsis muaj kab mob sib kis.

Kauj Ruam 3: Ntsuas cov khoom siv

Ntsuas qhov ntau ntawm cov khoom sib txawv raws li qhov xav tau proportions. Feem ntau, qhov sib xyaw ntawm cov cement thiab xuab zeb feem ntau yog 1: 3. Cov tshuaj ntxiv xws li HPMC yuav tsum suav txog 1-5% los ntawm qhov hnyav ntawm cov hmoov cement.

Piv txwv li, yog tias koj siv:

- 150 grams ntawm cement thiab 450 grams xuab zeb.

- Piv txwv tias koj yuav siv 2% los ntawm qhov hnyav ntawm HPMC cement hmoov, koj yuav ntxiv 3 grams ntawm HPMC hmoov

Kauj Ruam 4: Sib tov cov cement thiab xuab zeb

Ntxiv cov ntsuas cement thiab xuab zeb rau hauv lub thawv sib tov thiab do zoo kom txog thaum sib tov.

Kauj ruam 5: Ntxiv HPMC

Tom qab cov cement thiab xuab zeb sib tov, HPMC ntxiv rau hauv lub nkoj sib tov. Nco ntsoov ntsuas nws kom raug kom tau qhov feem pua ​​​​yuav xav tau. Sib tov HPMC rau hauv qhov sib tov qhuav kom txog thaum tag nrho dispersed.

Kauj Ruam 6: Ntxiv dej

Tom qab sib tov cov khoom qhuav, ntxiv dej ntxiv rau hauv lub thawv sib tov. Siv cov dej-cement piv uas sib haum rau hom pobzeb nplaum uas koj npaj yuav ua. Ua maj mam thaum ntxiv dej rau qhov sib tov.

Kauj Ruam 7: Sib tov

Sib tov cov dej nrog cov khoom qhuav thiab xyuas kom nws muaj qhov sib xws. Siv qhov chaw qis qis kom tau txais qhov xav tau kev ntxhib los mos. Sib tov siv cov cuab yeej sib tov kom txog thaum tsis muaj pob lossis cov hnab ntim qhuav.

Kauj Ruam 8: Cia lub nplaum zaum

Thaum cov nplais nplaum sib xyaw kom zoo, cia nws zaum li 10 feeb ua ntej siv. Lub sijhawm no, nws yog qhov zoo tshaj los npog thiab kaw lub thawv sib xyaw kom cov nplaum tsis qhuav tawm.

Yog li ntawd! Tam sim no koj muaj cov nplais kom qhuav cov nplaum ua los ntawm HPMC.

Hauv kev xaus, HPMC yog ib qho tseem ceeb ntxiv uas tuaj yeem nqa ntau yam txiaj ntsig rau cov nplais nplaum. Los ntawm kev ua raws li cov kauj ruam saum toj no, koj tuaj yeem ua tiav tsim cov khoom zoo, ceev-qhuav cov nplais nplaum nplaum. Nco ntsoov siv qhov sib piv ntawm cov ntaub ntawv kom raug thiab ntsuas qhov ntsuas HPMC hmoov kom tau qhov feem pua ​​​​qhov hnyav. Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem sib xyaw kom zoo kom tau txais kev ntxhib los mos zoo ib yam thiab ua kom qhov ua tau zoo ntawm cov nplaum.
