Bhabha uthuthu Iceramsite yenziwe ngothuthu lwempukane njengeyona nto ingundoqo ekrwada (malunga ne-85%), ixutywe nesixa esifanelekileyo sekalika (okanye i-calcium carbide slag), igypsum, imixube, njl. njl. I-Ceramsite ineepropathi ezigqwesileyo, ezinje ngoxinaniso oluphantsi, amandla acinezelayo e-cylinder ephezulu, i-porosity ephezulu, i-coefficient yokuthambisa okuphezulu, ukumelana neqabaka, kunye nokusebenza okugqwesileyo kokumelana ne-alkali. Ngokukodwa ngenxa yoxinano oluphantsi lweceramsite, i-porousness yangaphakathi, ukumila okufanayo kunye nokwakheka, kunye namandla athile kunye nokuqina, ineenzuzo zobunzima bokukhanya, ukuxhathisa umhlwa, ukumelana neqabaka, ukuxhathisa inyikima kunye nokugquma kakuhle (ukugcina ubushushu, ubushushu. ukugquma, ukugquma isandi, ukugquma, njl.). tide) kunye nezinye iimpawu ezisebenzayo. Ukusebenzisa ezi zakhiwo zibalaseleyo ze-ceramsite, zinokusetyenziswa ngokubanzi kwizinto zokwakha, i-horticulture, ukutya kunye nesiselo, izinto zokufakelwa kwe-refractory, imboni yeekhemikhali, i-petroleum kunye namanye amacandelo. Ekuqaleni kokuveliswa kunye nokuveliswa kwe-ceramsite, yayisetyenziswa kakhulu kwintsimi yezinto zokwakha. Ngenxa yophuhliso oluqhubekayo lwetekhnoloji kunye nokuqonda okunzulu kwabantu kwiipropati ze-ceramsite, ukusetyenziswa kwe-ceramsite sele kudlule umda wezinto zokwakha, kwaye ukusetyenziswa kwayo kuye kwandiswa ngokuqhubekayo. intsimi. Ngoku ukusetyenziswa kwe-ceramsite kwizinto zokwakha kuye kwehla ukusuka kwi-100% ukuya kwi-80%, kwaye isicelo kwezinye iinkalo siye sabalelwa kwi-20%. Ngophuhliso oluqhubekayo lokusetyenziswa okutsha kweceramsite, umlinganiselo wayo kwezinye iinkalo uya kunyuka ngokuthe ngcembe.
Iipropati ze-fly ash ceramsite
Isizathu sokuba i-fly ash ceramsite iphuhliswe ngokukhawuleza kwihlabathi jikelele kukuba ineempawu ezininzi ezintle ezingenazo ezinye izinto. Le propathi igqwesileyo iyenza ingenakuthathelwa indawo zezinye izinto. Ezi zakhiwo zibalaseleyo zinemiba ilandelayo.
1. Ubuninzi obuphantsi kunye nobunzima obulula. Ubuninzi bobuninzi be-fly ash ceramsite ngokwayo bungaphantsi kwe-1100kg/m3, ngokubanzi 300-900kg/m3. Ubuninzi bekhonkrithi eyenziwe nge-fly ash ceramsite njenge-aggregate yi-1100-1800kg/m3, kunye namandla ahambelanayo oxinzelelo lwekhonkrithi yi-30.5-40.0Mpa. Isici esikhulu se-ceramsite kukuba lukhuni ngaphandle, kwaye kukho ezininzi i-micropores ngaphakathi. Ezi micropores zinika i-ceramsite iimpawu zayo zobunzima bokukhanya. Ubuninzi beNo.
2. I-Insulation kunye nokushisa ukushisa. Ngenxa yobungaphakathi bayo obunemingxuma, ifly ash ceramsite ineempawu ezilungileyo zokugquma ubushushu. I-conductivity ye-thermal yekhonkrithi elungiselelwe kunye nayo ngokuqhelekileyo i-0.3 ukuya kwi-0.8 W / (m·k), eyi-1 ukuya ku-2 ngamaxesha angaphantsi kwekhonkrithi eqhelekileyo. Ngoko ke, izakhiwo ze-ceramsite zinendawo efanelekileyo yokushisa.
3. Ukumelana nomlilo okulungileyo, i-ceramsite inokumelana nomlilo obalaseleyo. Impukane eqhelekileyo ash ceramsite ikhonkrithi okanye impukane ash ceramsite block idibanisa ukugqunyelelwa thermal, ukuxhathisa inyikima, ukumelana neqabaka, ukumelana nomlilo kunye nezinye iipropati, ingakumbi ukumelana nomlilo ngaphezu kwamaxesha ama-4 ukuba ikhonkrithi eqhelekileyo. Ngexesha elifanayo le-refractory, ubukhulu bekhonkrithi ye-ceramsite buncinci ngama-20% kunobumba obuqhelekileyo. Ukongeza, i-fly ash ceramsite ingalungisa ikhonkrithi ephikisayo kunye ne-refractoriness engaphantsi kwe-1200 ℃. Kwiqondo lokushisa eliphezulu le-650 ° C, ikhonkrithi ye-ceramsite inokugcina i-85% yamandla kwindawo yokushisa. Ikhonkrithi eqhelekileyo inokugcina kuphela i-35% ukuya kwi-75% yamandla ayo kwiqondo lokushisa.
4. Ukusebenza kakuhle kwenyikima. Ikhonkrithi yeCeramsite inokusebenza kakuhle kwe-seismic ngenxa yobunzima bayo obukhanyayo, imodyuli ephantsi ye-elastic kunye nokumelana nokuguquguquka okuhle.
5. Ukufunxwa kwamanzi aphantsi, ukuxhathisa okulungileyo kweqabaka kunye nokuqina. Iasidi, i-alkali corrosion kunye nokusebenza kokumelana neqabaka kwekhonkrithi yeceramsite ingcono kunekonkrithi eqhelekileyo. KwiNombolo ye-250 ye-fly ash ceramsite ikhonkrithi, ilahleko yamandla ye-15 ye-freeze-thaw cycles ayikho ngaphezu kwe-2%. Ikhonkrithi yeCeramsite sisixhobo sokwakha esigqwesileyo kwaye kufuneka sikhuthazwe ngamandla kwaye sisetyenziswe.
