Umhlaba we-Diatomaceous, owaziwa njengomgubo wentaba, umgubo wefosili okanye umgubo we-radiolaria, lilitye le-biogenic siliceous sedimentary rock, eliqulunqwe kakhulu ziintsalela ze-siliceous ze-diatoms kunye nezinye ii-microorganisms. Kukho iinguqulelo ezininzi zesiNgesi, ezivela kumaphephandaba kunye namaxesha: Tripoli, Tripolite, TripoliEarth, Tripoli-Powder, Diatomite.
I-Diatomite lilitye lentlenga elinombala okhanyayo elidityaniswe ikakhulu ngamathambo e-siliceous e-diatom. Lilitye elinemingxuma kakhulu elinobungakanani besuntswana elicolekileyo kunye nomxhuzulane othile ophantsi. Ezi mpawu ziyenza ibe luncedo njengesixhobo sokucoca imidiya, i-absorbent, kwaye njengesizalisi esikhaphukhaphu serabha, ipeyinti, kunye neeplastiki. Xa i-diatomite ityunyuziwe ibe ngumgubo, ibizwa ngokuba "ngumhlaba wediatomaceous," okanye i-DE Diatomite Ethathwe kwiintsalela ze-microscopic yolwandle oluyi-fossilized okanye i-algaes yamanzi ahlaziyekileyo, i-diatomite yiminerali eyenzeka ngokwemvelo, esetyenziswa kwizinto ezininzi ezisetyenziswa kwi-cosmetics ukuya kuhluzo. .
Inxalenye ephambili yeekhemikhali zomhlaba we-diatomaceous yi-silicate. Umxholo we-SiO2 ungomnye wezibonakaliso zomxholo we-diatom kwi-diatomite ore, kunye ne-SiO2 ephezulu inomgangatho omhle. Umhlaba weDiatomaceous une-1% ~5% yamanzi, kwaye ubushushu belahleko yamanzi kumanzi acolloidal yi-110 ~ 250 °C.
Ukusetyenziswa kweDiatomite kunye neDiatomaceous Earth
I-diatomite isoloko isetyenziswa njengesongezo xa kusenziwa isamente ye-portland. I-diatomite ephezulu iqulethe i-silica engaphezu kwe-80%, kwaye yongezwa kwinkqubo yokwenza i-samente ukunyusa umxholo we-silica wemveliso. I-Diatomite ethe ngqo esuka emgodini iyatyunyuzwa kwaye ixutywe nekalika, i-shale, okanye ezinye izinto ezisetyenziselwa ukwenza isamente.
Izinto ezine eziphambili zokusetyenziswa kwe-diatomite e-United States ngexesha le-2017 yayiyi-filtration (50%), i-aggregate yokukhanya (30%), i-fillers (15%), kunye ne-absorbents (5%). Iimpawu ze-diatomite ezenza kube luncedo kwezi zicelo zidweliswe ngezantsi.
- Ubungakanani besuntswana elincinci
- I-porosity ephezulu
- Indawo ephezulu
- Ukwakhiwa kwe-siliceous engasebenziyo
- Umxhuzulane okhethekileyo ophantsi
