Yuav ua li cas txiav txim siab yog Magnesium Oxide tau nqus dej noo

Kev hloov xim, duab, thiab qib ntawm clumping tuaj yeem siv los ntsuas seb magnesium oxide puas tau nqus dej noo. Magnesium oxide tuaj yeem clump lossis solidify tom qab nqus dej noo, hloov los ntawm cov hmoov dawb xoob mus rau xim grey tsaus.

1. Kev ntsuas qhov tshwm sim thiab cov khoom

Xim Hloov: Magnesium oxide feem ntau yog cov hmoov dawb lossis me ntsis dawb. Cov xim ua npub lossis greyish -dawb tom qab nqus dej.

Kev hloov pauv morphological: Cov khoom sib txuas rau ib leeg thiab tsim cov pob me me thaum lub sijhawm pib ntawm kev nqus dej. Cov pob tawv tawv lossis cov ntaub npog npog uas nyuaj rau kev tsoo ntawm tes yog qhov cuam tshuam ntawm kev txhim kho ntxiv.

Txo Flowability: Nws nqus tau yooj yim thiab ntws zoo thaum nws tsis nqus dej noo. Cov hmoov clumps ua ke thiab dhau los ua dej tsawg dua tom qab nqus dej noo.

Kev nqus dej sib sib zog nqus ua rau lub pob zeb nyuaj, zoo li cov khoom siv uas qhia tau tias muaj kev poob haujlwm tseem ceeb, qhov kev nqus dej me ntsis zoo li cov pob zeb xoob uas tuaj yeem rub tawm ntawm tes.

2. Cov qauv siv rau cov dej noo

Cov ntsiab lus ntawm Moisture

Kev ntsuas lub xeev

Kev siv cuam tshuam

Tsawg dua lossis sib npaug li 1.5%

Li qub (nrog rau cov dej crystallisation)

Tsis muaj kev cuam tshuam

1.5%

Overabundance ntawm Sab Nraud Moisture thiab Absorbed Moisture

Qhov cuam tshuam zoo thiab xav tau kev kho mob

Thaum muaj huab cua ntau dhau lawm, magnesium oxide reacts nrog CO2 thiab dej los tsim cov magnesium carbonate, uas txo qis MgO qib.

3. Rapid On -Tsev Kev Ntsuas Qhov Chaw

Test ntawm Tes Squeezing

Nyem ib qho qauv me me maj mam:

Nws disperses yooj yim thiab absorbs noo noo tsuas yog me ntsis.

Hard thiab unbreakable nrog rau nruab nrab mus rau hnyav nqus noo noo.

Txoj kev nthuav dav thiab ziab

Tom qab kis tus qauv clumped tawm ntawm lub tais kom qhuav, cia nws cua qhuav rau ob mus rau plaub teev nyob rau hauv ib qho chaw ventilated:

recovers its looseness =>Nws tseem siv tau;

Kev downgrading yog qhia vim hais tias kev ua si tseem nyuaj.

Kev tshuaj xyuas qhov chaw cia khoom

puas los yog qhib packing → tsis tshua muaj kev cuam tshuam rau noo noo nqus; warehouse av noo> 50%

Thaum cov dej noo-cov txheej txheem pov thawj, suav nrog kev siv cov khoom siv desiccants lossis ib lub hnab yas sab hauv, tau ua haujlwm.

4. Cov lus qhia txog kev xeem

Nws raug nquahu kom xa cov qauv mus rau CNAS-cov ntaub ntawv pov thawj rau kev ntsuas cov ntsiab lus magnesium oxide yog tias lawv yuav tsum tau siv rau kev ua haujlwm siab -precision ntau lawm (xws li magnesium-raws li cov khoom siv los yog cov khoom siv hluav taws xob) txhawm rau lav kev ua haujlwm siab dua lossis sib npaug li 60%. Kev poob haujlwm tsis tuaj yeem ntsuas los ntawm kev soj ntsuam pom ib leeg.

Rau kev ntsuam xyuas kom raug, kev ntsuas dej (HG/T 3928-2012) yuav tsum tau ua ke nrog kev khaws cia ntev lossis kev siv tseem ceeb.
