Iimpawu ze-microstructure ze-diatomite

Ukwakhiwa kweekhemikhali zomhlaba we-diatomaceous ikakhulu yi-SiO2, kodwa isakhiwo sayo si-amorphous, oko kukuthi, i-amorphous. Le SiO2 i-amorphous ikwabizwa ngokuba yi-opal. Enyanisweni, yi-amorphous colloidal i-SiO2 equlethe amanzi, enokuthi ibonakaliswe njenge-SiO2⋅nH2O. Ngenxa yeendawo ezahlukeneyo zemveliso, umthamo wamanzi uhlukile; i-microstructure yeesampulu ze-diatomite inxulumene ikakhulu neentlobo ze-diatoms ezigciniweyo. Ngenxa yeentlobo ezahlukeneyo ze-diatoms, isakhiwo se-microscopic ye-diatomite ore eyenziweyo Kukho ukungafani okucacileyo kwisakhiwo, ngoko kukho ukungafani ekusebenzeni. Oku kulandelayo yidiphozithi ye-diatomite eyenziwe ngokuyintloko ngamadiphozithi asemhlabeni kwindawo ethile kwilizwe lethu esiye safunda, kwaye i-diatoms ihambelana kakhulu.

Ukusetyenziswa kwe-diatomite

Ngenxa ye-microstructure ekhethekileyo ye-diatomite, inoluhlu olubanzi lwezicelo kwiinkalo ezininzi ezifana nezixhobo zokwakha, iikhemikhali, ezolimo, ukukhuselwa kwendalo, ukutya, kunye nobuchwepheshe obuphezulu. EJapan, i-21% yomhlaba we-diatomaceous isetyenziswe kwishishini lezinto zokwakha, i-11% isetyenziselwa izinto eziphikisayo, kwaye i-33% isetyenziselwa abathwali kunye nabagcwalisi. Okwangoku, iJapan iphumelele iziphumo ezilungileyo ekuphuhliseni nasekusetyenzisweni kwezinto ezintsha zokwakha.

Isishwankathelo, izicelo eziphambili ze-diatomite zezi:

(1) Sebenzisa ubume bayo be-microporous ukulungiselela izixhobo ezahlukeneyo zoncedo lokucoca kunye nenkxaso ye-catalyst. Le yenye yezona zinto zisetyenziswayo kwi-diatomaceous earth. Isebenzisa ngokupheleleyo iimpawu ze-microstructure yomhlaba we-diatomaceous. Nangona kunjalo, i-ore ye-diatomaceous yomhlaba esetyenziswa njengoncedo lokucoca ithandwa kakhulu kwi-corinosites, kwaye i-ore yomhlaba ye-diatomaceous enesakhiwo somgca we-algae njenge-catalyst carrier ingcono kuba i-algae ehambelanayo inomphezulu omkhulu wangaphakathi.

(2) Ukulungiswa kokugcinwa kobushushu kunye nezixhobo eziphikisayo. Phakathi kwezinto zokufakelwa kwe-thermal ezingaphantsi kwe-900 ° C, i-diatomite i-thermal insulation refractory izitena zezona zikhethwa kakhulu, eziyenye yezona ndawo ziphambili zokusetyenziswa kwemigodi ye-diatomite kwilizwe lam.

(3) Umhlaba weDiatomaceous ungasetyenziswa njengomthombo oyintloko weSiO2 esebenzayo. Ekubeni i-SiO2 emhlabeni we-diatomaceous i-amorphous, inokusebenza okuphezulu. Umzekelo, kulungele kakhulu ukuyisebenzisa ukusabela ngezinto eziluhlaza ze-calcareous ukulungiselela ibhodi ye-calcium silicate izinto ezingatshi umlilo. Ngokuqinisekileyo, ukungcola okuthile kufuneka kususwe kwi-ore ye-diatomite ephantsi.

(4) Sebenzisa iimpawu zayo ze-microporous adsorption ukulungiselela i-antibacterial and antifungal agents. Oku kukwangomnye wezicelo ezitsha ezibalulekileyo ze-diatomite, into esebenzayo kunye nemiphumo yendalo. Ubude bacillus ngokubanzi 1-5um, ububanzi cocci yi 0.5-2um, kwaye ubungakanani pore emhlabeni diatomaceous yi 0.5um, ngoko ke ifiltha element eyenziwe ngomhlaba diatomaceous inokususa iintsholongwane, ukuba incamathele kwi-diatomaceous umhlaba filter element Ii-Antibacterial kunye ne-photosensitizers zineempembelelo ezingcono ze-antibacterial kunye ne-bactericidal enokuthi ibe nemiphumo engcono yokulwa ne-antibacterial kunye ne-bactericidal. injongo yokukhutshwa kancinci kunye neziphumo zexesha elide. Ngoku, abantu banokusebenzisa iindlela zobuchwepheshe obuphezulu ukulungiselela i-diatomaceous earth-type anti-mildew kunye nezixhobo ezisebenzayo ze-antibacterial kunye nomhlaba we-diatomaceous njengomthwali.
