Dhulka Diatomaceous, oo loo yaqaan bur buur, budada fosil ama budada radiolaria, waa dhagax sedimentary biogenic siliceous, inta badan ka kooban hadhaa siliceous of diatoms iyo microorganisms kale. Waxaa jira tarjumaadyo badan oo Ingiriis ah, kuwaas oo ka soo baxa wargeysyada iyo wargeysyada: Tripoli, Tripolite, TripoliEarth, Tripoli-Powder, Diatomite.
Diatomite waa dhagax sedimentary ah oo midab khafiif ah leh oo inta badan ka kooban haraaga lafaha siliceous ee diatoms. Waa dhagax aad u daloola oo leh xajmi walxeed wanaagsan iyo cufis gaar ah oo hooseeya. Qalabkan ayaa ka dhigaya mid faa'iido leh sida warbaahinta shaandhada, nuugista, iyo buuxinta khafiifka ah ee caagga, rinjiga, iyo balaastikada. Marka diatomite lagu burburiyo budo, waxaa badanaa loo yaqaan "dhulka diatomaceous," ama DE Diatomite Ka soo hadhaaga badda fossilized microscopic ama algaes biyaha saafiga ah, diatomite waa macdan si dabiici ah u dhacda, macdan badan oo loo isticmaalo noocyo kala duwan oo codsiyo ah oo laga soo saaro qurxinta ilaa sifeynta. .
Qaybta ugu muhiimsan ee kiimikada ee dhulka diatomaceous waa silicate. Nuxurka SiO2 waa mid ka mid ah tilmaamayaasha ka kooban diatoms ee macdanta diatomite, SiO2 sarena waa mid tayo wanaagsan leh. Dhulka diatomaceous wuxuu ka kooban yahay 1% ~ 5% biyo, iyo heerkulka biyaha ee luminta biyaha kolloidal waa 110 ~ 250 ° C
Isticmaalka Diatomite iyo Diatomaceous Earth
Diatomite waxaa inta badan loo isticmaalaa wax lagu daro soo saarista sibidhka portland. Diatomite tayo sare leh ayaa ka kooban in ka badan 80% silica, waxaana lagu daraa habka sibidhka si kor loogu qaado maadada silica ee alaabta. Diatomite tooska ah ee miinada waa la jajabiyaa oo lagu daraa dhagaxa nuuradda, shale, ama walxaha kale ee loo isticmaalo samaynta sibidhka.
Afarta adeegsi ee ugu muhiimsan ee diatomite gudaha Maraykanka inta lagu jiro 2017 waxay ahaayeen sifaynta (50%), wadarta iftiinka (30%), buuxinta (15%), iyo nuugista (5%). Tilmaamaha diatomite ee ka dhigaya mid waxtar u leh codsiyadan ayaa hoos ku taxan.
- Cabbirka walxaha yaryar
- Porosity sare
- Aagga sare ee dusha sare
- Halabuurka siliceous ee aan firfircoonayn
- Culays gaar ah oo hooseeya
