Iyo microstructure maitiro e diatomite

Kemikari yepasi diatomaceous inonyanya SiO2, asi chimiro chayo ndeye amorphous, kureva, amorphous. Iyi amorphous SiO2 inonziwo opal. Muchokwadi, imvura-ine amorphous colloidal SiO2, inogona kuratidzwa seSiO2⋅nH2O. Nekuda kwenzvimbo dzakasiyana dzekugadzira, huwandu hwemvura hwakasiyana; iyo microstructure ye diatomite samples inonyanya kuenderana nemhando dze diatoms dzakaiswa. Nekuda kwemhando dzakasiyana dzemadiatom, iyo microscopic chimiro cheiyo yakaumbwa diatomite ore Pane misiyano iri pachena muchimiro, saka pane misiyano mukuita. Inotevera dhipoziti yediatomite inoumbwa zvakanyanya nepasi pedhipoziti mune imwe nzvimbo munyika yedu yatakadzidza, uye madiatoms anonyanya mutsara.

Kushandiswa kwe diatomite

Nekuda kweiyo yakasarudzika microstructure ye diatomite, ine huwandu hwakasiyana hwekushandisa muminda yakawanda senge zvekuvakisa, makemikari, zvekurima, kuchengetedza kwezvakatipoteredza, chikafu, uye yakakwirira-tech. MuJapan, 21% yepasi diatomaceous inoshandiswa muindasitiri yezvivakwa, 11% inoshandiswa muzvinhu zvinoramba, uye 33% inoshandiswa mukutakura uye mafirita. Parizvino, Japan yakawana mhedzisiro yakanaka mukuvandudza nekushandiswa kwezvinhu zvitsva zvekuvaka.

Muchidimbu, mashandisirwo makuru ediatomite ndeaya:

(1) Shandisa iyo microporous chimiro kugadzirira akasiyana mafirita ekubatsira zvinhu uye zvinotsigira zvinotsigira. Ichi ndicho chimwe chekushandiswa kukuru kwepasi diatomaceous. Inoshandisa zvizere microstructure maitiro e diatomaceous pasi. Nekudaro, iyo diatomaceous yepasi ore inoshandiswa sesefa yerubatsiro inonyanya kupfuma mumacorinosites, uye iyo diatomaceous pasi ore ine mutsara algae chimiro sechinotakura chinotakura zviri nani nekuti linear algae ine yakakura kwazvo yemukati.

(2) Kugadzirira kwekuchengetedza kupisa uye zvinhu zvinoramba. Pakati pezvinhu zvinopisa zvinopisa zviri pasi pe900 ° C, diatomite thermal insulation refractory zvidhinha ndiyo yakanyanya kunaka sarudzo, inovawo imwe yeminda mikuru yekushandisa yemigodhi yediatomite munyika yangu.

(3) Diatomaceous pasi inogona kushandiswa sechinhu chikuru cheSiO2 inoshanda. Sezvo iyo SiO2 mune diatomaceous pasi iri amorphous, ine yakakwirira reactivity. Semuyenzaniso, yakanyatsokodzera kuishandisa kuita necalcareous raw materials kugadzirira calcium silicate board isingapfure zvinhu. Ehe, kumwe kusvibiswa kunofanirwa kubviswa kubva kune yakaderera-giredhi diatomite ore.

(4) Shandisa microporous adsorption maitiro kugadzirira antibacterial uye antifungal agents. Ichi zvakare chimwe chezvitsva zvakakosha zvekushandisa diatomite, inova chinhu chinoshanda chine ecological mhedzisiro. Kureba kweiyo bacillus kunowanzo 1-5um, dhayamita yecocci i 0.5-2um, uye saizi yepore yediatomaceous pasi i 0.5um, saka iyo sefa chinhu chakagadzirwa nediatomaceous pasi chinogona kubvisa mabhakitiriya, kana chakabatanidzwa kune diatomaceous pasi sefa element Antibacterial agents uye photosensitizers vane sterilization yekuwedzera uye mabhakitiriya anogona kuita zvirinani kuita antibacterial mhedzisiro, uye mabhakitiriya anogona kugadzirwa nezvimwe zvinhu. chinangwa chekunonoka-kusunungurwa uye kwenguva refu migumisiro. Iye zvino, vanhu vanogona kushandisa nzira dzepamusoro-soro kugadzirira diatomaceous pasi-mhando anti-mildew uye antibacterial functional materials ine diatomaceous pasi semutakuri.
