Dhulka Diatomaceous waa nooc ka mid ah dhagaxa siliceous ah oo inta badan loo qaybiyo wadamada sida Shiinaha, Maraykanka, Japan, Denmark, France, Romania, iwm.

Waxa ku jira qadar yar oo ah Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, iyo walxo dabiici ah.SiO2 inta badan waxay ka badan tahay 80%, ugu badnaan 94%.Maaddada oksaydhka birta ee dhulka diatomaceous ee tayada sare leh guud ahaan waa 1-1.5%, iyo waxa ku jira aluminium oksaydhku waa 3-6%.Halabuurka macdanta ee diatomite ayaa ah inta badan Opal iyo noocyadeeda, oo ay ku xigto macdanta dhoobada hydromica, Kaolinite iyo qashinka macdanta.Qashinka macdanta waxaa ka mid ah quartz, feldspar, Biotite iyo walxaha organic.

Dhulka Diatomaceous wuxuu ka kooban yahay SiO2 amorphous wuxuuna ka kooban yahay xaddi yar oo Fe2O3, CaO, MgO, Al2O3, iyo wasakh dabiici ah.Dhulka diatomaceous caadi ahaan waa huruud khafiif ah ama cawl khafiif ah, jilicsan, dalool leh, oo khafiif ah.Waxaa caadi ahaan loo isticmaalaa warshadaha sida walxaha dahaarka, alaabta shaandhaynta, buuxinta, alaabta shiidada, alaabta ceeriin ee galaas biyaha, wakiilada midabaynta, qalabyada filter dhulka diatomaceous, sidayaal kicinta, iwm.

Faa'iidooyinka isticmaalka dhulka diatomaceous: pH dhexdhexaad ah, aan sun ahayn, waxqabadka ganaax wanaagsan, waxqabadka adsorption xooggan, cufnaanta cufnaanta fudud, heerka nuugista saliidda ee 115%, ganaaxyo u dhexeeya 325 mesh ilaa 500 mesh, isku-dhafka isku dhafan ee wanaagsan, xannibaad la'aanta mashiinnada beeraha Tuubooyinka inta lagu jiro isticmaalka, waxay ka ciyaari karaan doorka qoyaanka ee ciidda, debciyaan tayada ciidda, kordhiyaan waqtiga bacriminta waxtarka leh, waxayna kor u qaadaan koritaanka dalagga.Warshadaha bacriminta isku dhafan: Bacriminta isku dhafan ee dalagyada kala duwan sida miraha, khudaarta, ubaxa iyo dhirta.Faa'iidooyinka isticmaalka dhulka diatomaceous: Dhulka diatomaceous waa in loo isticmaalo wax lagu daro sibidhka.Alaabta lagu daro daahan dhulka Diatomaceous waxay leeyihiin sifooyinka porosity sare, nuugista xoog leh, guryaha kiimikada deggan, xidho iska caabin ah, iska caabin kulaylka, iwm. Waxay ku siin karaan waxqabadka dusha sare, waafaqsan, dhumucdiisuna, iyo hagaajinta adhesion ee daahan.Sababtoo ah mugga daloolka weyn, waxay soo gaabin kartaa wakhtiga qalajinta ee daahan.Waxa kale oo ay yarayn kartaa xadiga resin-ka ee la isticmaalo waxayna dhimaysaa kharashyada.Alaabtan waxa loo tixgalinayaa in ay tahay badeecad matte ah oo hufnaan leh oo leh qiimo-ku-oolnimo wanaagsan, waxaana loo qoondeeyey badeecad ay soo saareen shirkado badan oo daahan caalami ah, oo si weyn loogu isticmaalo dhoobada diatomaceous-ka ee biyaha ku salaysan.
