Lub ntiaj teb diatomaceous yog dab tsi

Lub ntiaj teb diatomaceous yog ib hom pob zeb siliceous feem ntau faib rau hauv cov tebchaws xws li Tuam Tshoj, Tebchaws Meskas, Nyiv Pooj, Denmark, Fabkis, Romania, thiab lwm yam. Nws yog pob zeb sedimentary siliceous biogenic feem ntau yog tsim los ntawm cov seem ntawm cov diatoms thaum ub. Nws cov tshuaj lom neeg muaj pes tsawg leeg yog SiO2, uas tuaj yeem sawv cev los ntawm SiO2 · nH2O. Cov khoom siv hauv av yog opal thiab nws cov variants. Tuam Tshoj muaj cov khoom khaws cia ntawm 320 lab tons ntawm lub ntiaj teb diatomaceous, nrog rau qhov chaw cia khoom yav tom ntej ntawm ntau dua 2 billion tons, feem ntau nyob rau sab hnub tuaj thiab sab qaum teb sab hnub tuaj ntawm Tuam Tshoj. Ntawm lawv, Jilin, Zhejiang, Yunnan, Shandong, Sichuan thiab lwm lub xeev muaj cov khoom khaws cia loj dua thiab loj dua.
Lub luag haujlwm ntawm lub ntiaj teb diatomaceous

1. Kev nqus tau zoo ntawm formaldehyde

Lub ntiaj teb diatomaceous tuaj yeem nqus tau formaldehyde zoo thiab kuj muaj peev xwm nqus tau cov pa phem xws li benzene thiab ammonia. Qhov no yog vim nws qhov tshwj xeeb "molecular sieve" zoo li qhov pore layout, uas muaj cov khoom lim thiab adsorption zoo, thiab tuaj yeem daws tau qhov teeb meem ntawm huab cua ua qias tuaj hauv cov tsev niaj hnub.

2. Tshem tawm cov ntxhiab tsw phem

Cov pa oxygen tsis zoo uas tso tawm los ntawm lub ntiaj teb diatomaceous tuaj yeem tshem tawm ntau yam ntxhiab tsw, xws li cov pa luam yeeb siv lawm, cov ntxhiab pov tseg hauv tsev, cov ntxhiab tsiaj hauv lub cev, thiab lwm yam, tswj tau huab cua hauv tsev tshiab.

3. Kev hloov kho tsis siv neeg ntawm cov av noo huab cua

Lub luag haujlwm ntawm diatomaceous av yog los tswj cov av noo ntawm huab cua hauv tsev. Thaum qhov kub hloov pauv thaum sawv ntxov thiab yav tsaus ntuj lossis thaum lub caij hloov pauv, diatomaceous av tuaj yeem nqus thiab tso dej tawm raws li cov av noo hauv huab cua, yog li ua tiav lub hom phiaj ntawm kev tswj cov av noo ntawm ib puag ncig.

4. Muaj peev xwm nqus tau cov roj molecules

Lub ntiaj teb diatomaceous muaj tus yam ntxwv ntawm kev nqus roj. Thaum nws ua pa, nws tuaj yeem nqus cov roj molecules thiab teb rau cov tshuaj uas tsis muaj teeb meem rau tib neeg lub cev. Nws muaj cov nyhuv nqus roj zoo, tab sis lub luag haujlwm ntawm lub ntiaj teb diatomaceous tsis suav nrog kev nqus plua plav.

5. Muaj peev xwm rwb thaiv tsev thiab khaws cia cua sov

Lub ntiaj teb diatomaceous yog cov khoom siv rwb thaiv tsev zoo vim nws cov khoom tseem ceeb yog silicon dioxide. Nws cov thermal conductivity qis heev, thiab nws muaj cov yam ntxwv xws li porosity siab, qhov loj me me, rwb thaiv tsev, tsis kub hnyiab, suab rwb thaiv tsev, tiv taus corrosion, thiab lwm yam. Nws yog siv dav.
Cov av algae muaj ntau yam kev siv thiab feem ntau ntxiv rau kev ntxuav kom zoo nkauj, txhuam, tshuaj pleev exfoliating, tshuaj txhuam hniav, thiab lwm yam tshuaj tua kab hauv tsev lossis vaj.
