Halayen microstructure na diatomite

Abubuwan sinadaran da ke cikin ƙasa diatomaceous galibi SiO2 ne, amma tsarinsa amorphous ne, wato amorphous. Wannan amorphous SiO2 kuma ana kiransa opal. A haƙiƙa, SiO2 colloidal amorphous mai ɗauke da ruwa ne, wanda za'a iya bayyana shi azaman SiO2⋅nH2O. Saboda wurare daban-daban na samar da ruwa, abin da ke cikin ruwa ya bambanta; microstructure na samfuran diatomite yana da alaƙa da jinsin diatoms da aka ajiye. Saboda nau'o'in diatoms daban-daban, tsarin microscopic na diatomite tama da aka kafa Akwai bambance-bambance a bayyane a cikin tsari, don haka akwai bambance-bambance a cikin aikin. Wannan shi ne ajiyar diatomite da aka samar musamman ta hanyar ajiyar ƙasa a wani wuri a cikin ƙasarmu da muka yi nazari, kuma diatoms yawanci layi ne.

Aikace-aikacen diatomite

Saboda ƙananan ƙananan ƙwayoyin diatomite, yana da nau'o'in aikace-aikace a fannoni da yawa kamar kayan gini, sinadarai, noma, kare muhalli, abinci, da fasaha mai zurfi. A Japan, ana amfani da 21% na diatomaceous ƙasa a cikin masana'antar kayan gini, 11% ana amfani da su a cikin kayan haɓaka, kuma 33% ana amfani dashi a cikin masu ɗaukar kaya da masu cikawa. A halin yanzu, Japan ta sami sakamako mai kyau a cikin haɓakawa da kuma amfani da sababbin kayan gini.

A taƙaice, manyan aikace-aikacen diatomite sune:

(1) Yi amfani da tsarin sa na microporous don shirya kayan taimako daban-daban na tacewa da goyan baya. Wannan yana daya daga cikin manyan amfani da duniya diatomaceous. Yana yin cikakken amfani da sifofin microstructure na duniya diatomaceous. Duk da haka, diatomaceous ƙasa tama da ake amfani da matsayin tace taimako zai fi dacewa mai arziki a cikin corinosites, da diatomaceous ƙasa tama tare da mikakke algae tsarin a matsayin mai kara kuzari ya fi kyau saboda linear algae yana da wani babban saman ciki.

(2) Shirye-shiryen adana zafi da kayan haɓakawa. Daga cikin kayan da ake amfani da su na thermal da ke ƙasa da 900 ° C, tubalin diatomite thermal insulation refractory tubalin shine mafi kyawun zaɓi, wanda kuma shine ɗayan manyan wuraren aikace-aikacen ma'adinan diatomite a cikin ƙasata.

(3) Ana iya amfani da ƙasan diatomaceous azaman babban tushen SiO2 mai aiki. Tun da SiO2 a cikin diatomaceous ƙasa yana da amorphous, yana da babban aiki. Alal misali, yana da kyau a yi amfani da shi don amsawa tare da albarkatun ƙasa don shirya kayan hana wuta na calcium silicate board. Tabbas, ya kamata a cire wasu ƙazanta daga ma'aunin diatomite mai ƙarancin daraja.

(4) Yi amfani da sifofin adsorption na microporous don shirya magungunan ƙwayoyin cuta da ƙwayoyin cuta. Wannan kuma shine ɗayan sabbin mahimman aikace-aikacen diatomite, wanda shine kayan aiki mai aiki tare da tasirin muhalli. Tsawon bacillus gabaɗaya shine 1-5um, diamita na cocci shine 0.5-2um, kuma girman pore na ƙasan diatomaceous shine 0.5um, don haka abin tacewa da aka yi da ƙasa diatomaceous zai iya cire ƙwayoyin cuta, idan an haɗa shi da nau'in tacewa ta diatomaceous ƙasa mai tacewa Antibacterial agents da photosensitizers suna da mafi kyawun sterilization da sauran abubuwa masu cutarwa zuwa ƙwayoyin cuta da ƙwayoyin cuta. cimma manufar jinkirin-saki da tasiri na dogon lokaci. Yanzu, mutane na iya amfani da manyan hanyoyin fasaha don shirya nau'in diatomaceous duniya anti-mildew da kayan aikin antibacterial tare da diatomaceous ƙasa a matsayin mai ɗauka.
