Dhulka diatomaceous waa nooc ka mid ah dhagaxa siliceous oo inta badan ku baahsan wadamada sida Shiinaha, Mareykanka, Japan, Denmark, Faransiiska, Romania, iwm. Waa dhagax siliceous ah oo bayooloji ah, oo inta badan ka kooban haraaga diatoms-ka qadiimiga ah.

Waxaa ku jira xaddi yar oo Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, iyo walxo dabiici ah. SiO2 badanaa wuxuu ka badan yahay 80%, ugu badnaan 94%. Tirada oksaydhka birta ah ee dhulka diatomaceous tayo sare leh guud ahaan waa 1-1.5%, halka ka kooban oksaydhka aluminiumku uu yahay 3-6%. Halabuurka macdanta ee diatomite inta badan waa Opal iyo noocyadeeda, waxaana ku xiga macdanta dhoobada ah ee hydromica, Kaolinite iyo qashinka macdanta. Qashinka macdanta waxaa ka mid ah quartz, feldspar, Biotite iyo walxaha dabiiciga ah.

Dhulka diatomaceous wuxuu ka kooban yahay SiO2 aan qaab lahayn wuxuuna ka kooban yahay xaddi yar oo Fe2O3, CaO, MgO, Al2O3, iyo wasakhda dabiiciga ah. Dhulka diatomaceous badanaa waa huruud khafiif ah ama cawl khafiif ah, jilicsan, dalool leh, oo fudud. Waxaa badanaa loo isticmaalaa warshadaha sida walxaha dahaarka, walxaha shaandhaynta, buuxinta, walxaha shiididda, walxaha ceeriin ee galaaska biyaha, wakiilada decoration, qalabka shaandhaynta dhulka diatomaceous, sidayaasha kicinta, iwm.

Faa'iidooyinka isticmaalka dhulka diatomaceous: pH dhexdhexaad ah, aan sun ahayn, waxqabad wanaagsan oo laalaaban, waxqabad nuugid xooggan, cufnaanta khafiifka ah, heerka nuugista saliidda oo ah 115%, jilicsanaan u dhaxaysa 325 mesh ilaa 500 mesh, isku-darka isku-dhafka wanaagsan, xannibaad la'aan tuubooyinka mashiinnada beeraha inta lagu jiro isticmaalka, waxay ka ciyaari kartaa door qoyaan ciidda, waxay dabcisaa tayada ciidda, waxay dheereysaa waqtiga bacriminta ee waxtarka leh, waxayna kor u qaadi kartaa koritaanka dalagga. Warshadaha bacriminta isku-dhafan: Bacriminta isku-dhafan ee dalagyada kala duwan sida miraha, khudaarta, ubaxyada iyo dhirta. Faa'iidooyinka isticmaalka dhulka diatomaceous: dhulka diatomaceous waa in loo isticmaalaa sidii lagu daro sibidhka. Badeecadaha lagu daro dahaarka dhulka diatomaceous waxay leeyihiin astaamaha dalool sare, nuugid xooggan, sifooyin kiimiko oo deggan, iska caabin xirasho, iska caabin kulaylka, iwm. Waxay bixin karaan waxqabad dusha sare oo aad u fiican, iswaafajin, dhumuc, iyo isku-dhejin wanaagsan oo loogu talagalay dahaarka. Sababtoo ah mugga daloolka weyn, waxay gaabin kartaa wakhtiga qalajinta ee dahaarka. Waxay sidoo kale yareyn kartaa xaddiga resin la isticmaalo waxayna yareyn kartaa kharashyada. Badeecadan waxaa loo arkaa inay tahay badeecad dahaadh oo hufan oo leh kharash-oolnimo wanaagsan, waxaana loo aqoonsaday inay tahay badeecad ay sameeyeen soo-saarayaal badan oo caalami ah oo waaweyn oo dahaar ah, kuwaas oo si weyn loogu isticmaalo dhoobada diatomaceous ee biyaha ku salaysan.
