xov xwm

Cov diatoms hauvdiatomaceous ntiaj tebmuaj ntau yam sib txawv, xws li discs, koob, lub tog raj kheej, plaub thiab lwm yam. Qhov ntom ntom yog 0.3 ~ 0.5g / cm3, Mohs hardness yog 1 ~ 1.5 (diatom pob txha hais yog 4.5 ~ 5 hli), qhov porosity yog 80 ~ 90%, thiab nws tuaj yeem nqus dej 1.5 ~ 4 npaug ntawm nws qhov hnyav. Nws yog cua sov, tsis zoo conductor ntawm hluav taws xob thiab suab, melting point 1650 ~ 1750 ° C, siab chemical stability, insoluble nyob rau hauv tej yam muaj zog acid tsuas yog hydrofluoric acid, tab sis soluble nyob rau hauv muaj zog alkali tov.

Feem ntau ntawm silica ntawm diatomaceous ntiaj teb yog amorphous, thiab cov ntsiab lus ntawm soluble silicic acid nyob rau hauv alkali yog 50-80%. Amorphous SiO2 ua crystalline thaum rhuab mus rau 800-1000 ° C, thiab soluble silicic acid nyob rau hauv alkali yuav txo tau rau 20-30%. 1.5 Cov khoom ntxhia Diatomite yog ib hom pob zeb nrog cov qauv lom neeg. Nws yog tsim los ntawm 80-90%, thiab qee qhov mus txog ntau tshaj 90% ntawm diatom frustules. Cov neeg siv khoom tseem ceeb ntawm silicon oxide hauv dej hiav txwv thiab dej hauv pas dej yog diatoms, uas yog diatom sludge. Thaum lub sij hawm diagenesis, diatomite yog tsim los ntawm petrochemical theem. Diatom plhaub yog tsim los ntawm opal. Thaum lub sij hawm kev loj hlob thiab kev loj hlob ntawm diatoms, nws absorbs colloidal silica los ntawm dej thiab maj hloov mus rau hauv opal.

Qhov ntau diatom ntsiab lus nyob rau hauvdiatomaceous ntiaj teb, qhov tsawg impurities, cov xim dawb thiab qhov sib dua qhov zoo. Lub ntiajteb txawj nqus yog feem ntau 0.4-0.9. Vim tias diatomite muaj ntau lub plhaub qhov, lub diatomite muaj cov qauv ntxeem tau. Qhov porosity ntawm diatomite yog 90-92%. Nws muaj zog nqus dej thiab nplaum tus nplaig. Vim cov diatom hais me me, ua rau lub ntiaj teb diatomaceous zoo thiab du. Diatomaceous ntiaj teb yog insoluble nyob rau hauv acid (HCl, H2S04, HN03), tab sis soluble nyob rau hauv HF thiab K0H.

Diatomyog ib hom ntawm ib leeg-celled algae uas thawj zaug tshwm sim hauv ntiaj teb. Nws nyob hauv dej hiav txwv lossis dej hauv pas dej, thiab nws cov duab yog me me, feem ntau tsuas yog ob peb microns mus rau kaum microns. Diatoms tuaj yeem nqa tawm photosynthesis thiab nws tus kheej tsim cov organic teeb meem. Feem ntau loj hlob thiab rov tsim dua ntawm qhov txaus ntshai. Nws cov seem tau muab tso rau hauv lub ntiaj teb diatomaceous. Nws yog lub diatom no uas muab cov pa oxygen rau lub ntiaj teb los ntawm photosynthesis thiab txhawb kev yug me nyuam ntawm tib neeg, tsiaj txhu thiab nroj tsuag. Lub ntsiab ntawm lub ntiaj teb diatomaceous yog silicic acid. Muaj ntau qhov pores nyob rau saum npoo, uas tuaj yeem nqus tau thiab decompose cov ntxhiab tsw tshwj xeeb hauv huab cua, thiab muaj cov haujlwm ntawm cov av noo tswj thiab deodorization. Cov khoom siv hauv tsev tsim los siv lub ntiaj teb diatomaceous li raw cov ntaub ntawv tsis yog tsuas yog muaj cov yam ntxwv ntawm cov tsis-combustibility, dehumidification, deodorization thiab zoo permeability, tab sis kuj muaj peev xwm purify huab cua, suab rwb thaiv tsev, waterproof thiab tshav kub rwb thaiv tsev.

Jilin Yuantong Mining Co., Ltd. yog ib lub tuam txhab kev koom ua ke diatomite mining, kev tshawb fawb thiab kev tsim kho, ua, thiab tsim cov khoom lag luam diatomite series. Nws yog qib zoo tshaj plaws thiab cov khoom loj tshaj plaws ntawm cov zaub mov zoo sib xws hauv kuv lub tebchaws, thiab nws tseem yog lub ntiaj teb txoj kev loj hlob tam sim no kev cia siab Diatomite deposits. Peb lub tuam txhab tsuas yog tsim cov khoom lag luam diatomite xws li diatomite lim pab, diatomite fillers, thiab diatomite catalysts. Cov khoom lag luam txhim khu kev qha zoo thiab tsim nyog ntawm tus nqi, thiab tau txais txiaj ntsig zoo los ntawm cov neeg siv khoom.
