Dota rinobhururuka Ceramsite yakagadzirwa neash inobhururuka sezvinhu zvikuru (inenge 85%), yakasanganiswa nehuwandu hwakakodzera hwe lime (kana calcium carbide slag), gypsum, admixtures, nezvimwewo. Aggregate yakaitwa kubva mu natural hydraulic reaction. Ceramsite ine hunhu hwakanaka, hwakadai se low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, uye alkali-resistant aggregate reactivity yakanaka. Kunyanya nekuda kwe low density yeceramsite, internal porousness, uniform form uye composition, uye some strength and simplicity, ine mabhenefiti elight huremu, corrosion resistance, frost resistance, heat preservation and good insulation (heat preservation, heat insulation, sound insulation, etc.) uye mamwe mabasa akawanda. Ichishandisa hunhu hwakanaka hweceramsite, inogona kushandiswa zvakanyanya muzvivakwa, horticulture, food and drink, refractory insulation materials, chemical industry, petroleum and other sectors. Pakutanga kwekugadzirwa nekugadzirwa kweceramsite, yainyanya kushandiswa mumunda wezvivakwa. Nekuda kwekuvandudzwa kuri kuitwa tekinoroji uye kunzwisisa kwakadzama kwevanhu nezvehunhu hwe ceramsite, kushandiswa kwe ceramsite kwakatopfuura huwandu hwezvinhu zvekuvaka, uye kushandiswa kwayo kwave kuchiramba kuchiwedzerwa. Iye zvino kushandiswa kwe ceramsite muzvinhu zvekuvaka kwaderera kubva pa100% kusvika pa80%, uye kushandiswa mune zvimwe zvinhu kwave ne20%. Nekuvandudzwa kuri kuitwa kushandiswa kutsva kwe ceramsite, huwandu hwayo mune zvimwe zvinhu huchawedzera zvishoma nezvishoma.
Hunhu hwe fly ash ceramsite
Chikonzero nei fly ash ceramsite yakura nekukurumidza pasi rese ndechekuti ine hunhu hwakanaka kwazvo husina zvimwe zvinhu. Hunhu hwakanaka uhwu hunoita kuti isatsiviwe nezvimwe zvinhu. Hunhu hwakanaka uhwu hune zvinhu zvinotevera.
1. Huremu hushoma uye huremu hwakareruka. Huremu hwakawanda hwe fly ash ceramsite pachayo huri pasi pe 1100kg/m3, kazhinji 300-900kg/m3. Huremu hwekongiri yakagadzirwa ne fly ash ceramsite se aggregate i1100-1800kg/m3, uye simba rekumanikidza kongiri rinoenderana i30.5-40.0Mpa. Chinhu chikuru che ceramsite ndechekuti yakasimba kunze, uye kune ma micropores akawanda mukati. Ma micropores aya anopa ceramsite hunhu hwayo hwekureruka. Huremu hwe fly ash ceramsite concrete Nhamba 200 hunenge 1600kg/m3, nepo huremu hwekongiri yakajairika ine label imwechete huri pamusoro pe 2600kg/m3, uye musiyano uripo pakati pezviviri izvi i1000kg/m3.
2. Kudzivirira kupisa uye kudzivirira kupisa. Nekuda kwemukati mayo mune maburi, ceramsite ye fly ash ine hunhu hwakanaka hwekudzivirira kupisa. Kupisa kwekongiri yakagadzirwa nayo kunowanzova 0.3 kusvika 0.8 W/(m·k), iyo yakaderera ka1 kusvika kaviri pane kongiri yakajairika. Nokudaro, zvivakwa zve ceramsite zvine nharaunda yakanaka yekupisa.
3. Kudzivirira moto zvakanaka, ceramsite ine simba rakanaka rekudzivirira moto. Konkriti ye ceramsite ye fly ash kana fly ash ceramsite block inobatanidza insulation yekupisa, kudzivirira kudengenyeka kwenyika, kudzivirira chando, kudzivirira moto nezvimwe zvinhu, kunyanya kudzivirira moto kwakapfuura ka4 pane konkriti yakajairika. Munguva imwecheteyo yekuramba, ukobvu hwe ceramsite hwakatetepa ne20% kupfuura hwekonkriti yakajairika. Pamusoro pezvo, ceramsite ye fly ash inogonawo kugadzira konkriti inoramba ichidzivirira pasi pe1200℃. Pakupisa kwakanyanya kwe650 ° C, konkriti ye ceramsite inogona kuchengetedza 85% yesimba pakupisa kwemumba. Konkriti yakajairika inogona kuchengetedza 35% kusvika 75% chete yesimba rayo pakupisa kwemumba.
4. Kushanda zvakanaka kwepasi pevhu. Konkriti yeCeramsite ine kushanda zvakanaka kwepasi pevhu nekuda kwehuremu hwayo hushoma, modulus yakaderera uye kuramba kwayo kuchinjika.
5. Kunyudzwa kwemvura kushoma, kuramba chando zvakanaka uye kugara kwenguva refu. Kushanda kwekongiri yeceramsite ngura, acid, alkali uye kuramba chando kuri nani pane kwekongiri yakajairika. Kune kongiri ye 250 fly ash ceramsite, kurasikirwa nesimba kwe15 freeze-thaw cycles hakupfuuri 2%. Kongiri yeceramsite chinhu chakanaka chekuvaka uye chinofanira kukurudzirwa uye kushandiswa nesimba.
