Impahla ekrwada ekrwada

  • Calcium carbide

    Calcium khabhayithi

    Ikhalsiyam khabhayithi sisakhi esingaphiliyo, iikristali ezimhlophe, iimveliso zorhwebo ngamaqhuma amnyama-mnyama, kwaye icandelo lomnqamlezo limfusa okanye ngwevu. Isabela ngogonyamelo xa ihlangana namanzi, ivelisa iasithilini kunye nokukhupha ubushushu. Ikhalsiyam khabhayithi yinto ebalulekileyo ekrwada, esetyenziselwa ukuvelisa irhasi yeasithilini. Ikwasetyenziswa nakwi-organic synthesis, i-oxyacetylene welding, njl.njl. Iipropati zomzimba kunye neekhemikhali: I-ore ngumbala omthubi-mdaka okanye mnyama omnyama, kwaye imveliso esulungekileyo yikristale emhlophe (yona ene-CaC2 ephezulu imfusa). Inobuninzi be-2.22 g / cm3 kunye nendawo yokunyibilika ye-2300 ° C (enxulumene nomxholo weCaC2). Iphendula ngokukhawuleza xa idibana namanzi ukuvelisa iasithilini kwaye ikhuphe ubushushu. Indawo yokunyibilika iyatshintsha kunye nomxholo wecalcium khabhayithi owahlukileyo.

  • Bauxite

    IBauxite

    Elona candelo le-bauxite yi-alumina, ene-alumina ene-hydrated equkethe ukungcola kwaye luhlobo oluthile lwezimbiwa zomhlaba. Mhlophe okanye mhlophe qhwa, mthubi bumthubi okanye bomvu ngokukhanyayo ngenxa yomxholo wentsimbi. Ubunzima be-3.45g / cm3, ubunzima be-1 ~ 3, opaque kunye ne-brittle. Kunzima kakhulu ukunyibilika. Ingenakunyibilika emanzini, inyibilike kwi-asidi ye-sulfuric kunye nesisombululo se-sodium hydroxide. Ubukhulu becala isetyenziselwa ukunyibilikisa i-aluminium kunye nezinto zokwenza ukuba ziphinde zenziwe.
    Ukubumba kwe-bauxite kuyinkimbinkimbi kakhulu, kwaye ligama eliqhelekileyo leentlobo ezahlukeneyo ze-hydrous alumina ore enemithombo eyahlukeneyo yokuma komhlaba. Ezifana ne-boehmite, diaspore kunye ne-gibbsite (Al2O3 · 3H2O); ezinye zenziwe nge-diaspore kunye ne-kaolinite (2SiO2 · Al2O3 · 2H2O); ezinye zenziwe ikakhulu nge-kaolinite kwaye zilandela Ukwanda komxholo we-kaolinite wenza i-bauxite ngokubanzi okanye udongwe lwe-kaolinite. IBauxite yenziwa ngokubanzi yimozulu yemichiza okanye iziphumo zangaphandle. Zimbalwa iicaminerali ezicocekileyo, kwaye zihlala zinezimbiwa ezingcolileyo, ubuncinci okanye ubuncinci beetyuwa, iiminerali zentsimbi, iiminerali zeetitanium kunye neeminerali ezinzima.

  • Chamotte

    Chamotte

    I-Chamotte ngumgangatho ophezulu wodongwe owenziwe ngodongwe onzima oveliswe eZibo, kwiPhondo laseShandong, China. Umxholo oqhelekileyo we-Al2O3 we-chamotte ore yi-38%, emva kokubala umxholo we-Al2O3 umalunga ne-44%, kunye ne-Fe2O3 <2%. Ukwenziwa kuzinzile, ukuthungwa kuyafana, ubume buxinene, kwaye eli candelo limile okweqokobhe kwaye limhlophe. Isetyenziselwa ukuvelisa izinto zodongwe ezikumgangatho ophezulu. Ixesha lobuchwephesha yindawo yokuqala yodongwe oluqinileyo, izinto zeekhemikhali eziphambili zi-AL2O3 kunye ne-SiO2, ezihamba kunye nenani elincinci le-Fe2O3 kunye nokulandelwa kwe-Na2O kunye ne-K2O. Eyona izimbiwa - kaolin.

    I-chamotte esiyibiza ngokubanzi ibhekisa ku-CALCINED CLAY. . Umxholo we-Al2O3 kwi-chamotte ebalwayo imalunga ne-44%, kwaye umxholo we-Fe2O3 awukho ngaphezulu kwe-2%. Ukwenziwa kuzinzile, ukuthungwa kuyafana, ubume buxinene, kwaye eli candelo limile okweqokobhe.

    Imibala eqhelekileyo ye-chamotte emva kokubalwa kobushushu obuphezulu yile: mhlophe emsulwa, grey ukukhanya, mdaka mthubi mthubi, kunye nexabiso elincinci le-brown sheet yetsimbi.

  • Andalusite

    Andalusite

    I-Andalusite yiminerali ye-aluminosilicate, eyinto ekrwada yokwenza izinto ezingafunekiyo kunye ne-porcelain kwiiplagi. Yiminerali eqhelekileyo yenqanaba eliphantsi le-metamorphism ye-thermal, kwaye ihlala ifumaneka kumatye odaka xa unxibelelana nemimandla ye-metamorphic. Yenziwe ikakhulu phantsi kweemeko zokuphakama komhlaba kunye noxinzelelo olusezantsi kumgangatho wobushushu.

    I-Andalusite i-crystalar columnar, kwaye icandelo layo lomnqamlezo liphantse lisisikwere. Amakristal e-Andalusite aqokelelene ndawonye kwiimilo zeradial okanye zegranular. Abantu bahlala bebiza i-radial andalusites "ngamatye e-chrysanthemum", nto leyo ethetha ukuba zifana neembumba ze-chrysanthemum.
