Magnesium oxide uas tau nqus dej noo tuaj yeem kho tau los ntawm lub cev dispersing, ziab kom ua kom muaj zog, lossis txo qis, nyob ntawm qib ntawm agglomeration. Kev ya raws me ntsis-absorbing hais tuaj yeem siv ncaj qha tom qab dispersing. Nruab nrab agglomerated hais yuav tsum tau qhuav kom rov ua haujlwm. Hnyav agglomerated hais yog pom zoo rau downgrading.
1. Moisturized me ntsis: Lub cev Dispersing + Sun- ziab
Yam ntxwv: Cov khoom yog me ntsis nplaum, yooj yim tawg ntawm tes, thiab xim tseem dawb los yog me ntsis dawb.
Txoj Kev Kho Mob: Muab cov khoom tso rau hauv lub tais huv si thiab maj mam txhuam nws los ntawm ib lub sieve uas siv lub pas ntoo los yog sieve.
Tshaj tawm hauv qhov dej- qhov cua thiab qhov chaw qhuav rau huab cua- qhuav rau 2-4 teev, tsis txhob tshav ntuj ncaj qha thiab los nag.
Tom qab nws regains nws looseness, nws yuav siv tau ib txwm.
Haum rau cov xwm txheej dav dav uas tsis tas yuav muaj kev ua haujlwm siab.
2. Nruab Nrab Agglomerated: Tsawg-Tsub Qhuav + Sieving
Cov yam ntxwv: Cov clumps kuj nyuaj tab sis tuaj yeem tawg, xim tsaus me ntsis, thiab cov hmoov xav tias ntub.
Txoj Kev Kho Mob: Ua ntej, tsoo cov khoom loj thiab muab tso rau hauv lub tshuab ziab khaub ncaws;
Qhuav ntawm kwv yees li 150℃rau 1 teev, los yog, yog tias ua tau, ntawm 500℃rau 4 teev kom decompose nto magnesium hydroxide thiab rov ua nws cov haujlwm;
Tom qab ziab, sieve tshem tawm impurities, txias, thiab kaw rau cia.
Txoj kev no ua haujlwm zoo rov qab ua kom muaj dej thiab tshuaj lom neeg ntawm magnesium oxide, ua rau nws tsim nyog rau rov siv dua hauv cov khoom siv hauv tsev lossis tshuaj lom neeg.
3. Cementation hnyav: txo qis kom tsis txhob khib nyiab
Cov yam ntxwv: Nyuaj li pob zeb, nrog rau thaj chaw loj ntawm cementation, greyish - xim dub, thiab ua haujlwm tsis zoo.
Cov lus pom zoo kho mob:
Tsis pom zoo rau siab - qauv tsim (xws li precision ceramics, khoom siv hluav taws xob);
tuaj yeem muab sib xyaw me me rau hauv qis - cov khoom xyaw txheem;
Los yog hu rau tus neeg muag khoom raw khoom rau kev rov ua dua los txo cov peev txheej pov tseg.
Kev siv yuam kev hauv siab - cov txheej txheem precision tuaj yeem ua rau cov khoom tawg, lub zog tsis txaus, thiab lwm yam teeb meem.
Cov dej noo-cov ntaub ntawv pov thawj cia (kev tiv thaiv yog qhov tseem ceeb):
Khaws qhov chaw cia kom qhuav thiab zoo - qhov cua, tsuj hauv pem teb, thiab tswj cov av qis dua 50%;
Kaw lub ntim, thiab khi lub hnab kom nrawm yog tias tsis siv.
Ntxiv ib zaj duab xis yas sab hauv thiab kaw cov txheej txheej nrog cov dej noo- pov thawj hnab; Lub desiccant tuaj yeem muab tso rau hauv lub ntim, thiab ua raws li "thawj-hauv, ua ntej- tawm" txoj cai kom luv lub sijhawm cia.
