Uthuthu olubhabhayo I-ceramsite yenziwe ngothuthu oluyimpukane njengezinto eziphambili (malunga ne-85%), ixutywe nomlinganiselo ofanelekileyo welayimu (okanye i-calcium carbide slag), i-gypsum, izinto ezixutyiweyo, njl. I-aggregate elula eyenziweyo eyenziwe nge-hydraulic reaction yendalo. I-Ceramsite ineempawu ezintle kakhulu, ezifana noxinano oluphantsi, amandla aphezulu oxinzelelo lwe-cylinder, i-porosity ephezulu, i-high softening coefficient, ukumelana okuhle kweqabaka, kunye ne-alkali-resistant aggregate reactivity egqwesileyo. Ingakumbi ngenxa yoxinano oluphantsi lwe-ceramsite, i-porousness yangaphakathi, imo efanayo kunye nokwakheka, kunye namandla athile kunye nokuqina, ineenzuzo zobunzima obulula, ukumelana nokugqwala, ukumelana neqabaka, ukumelana nenyikima kunye nokufakelwa okuhle (ukugcinwa kobushushu, ukufakelwa kobushushu, ukufakelwa kwesandi, ukufakelwa kwe-insulation, njl. njl.) kunye nezinye iimpawu ezininzi. Ukusebenzisa ezi mpawu zibalaseleyo ze-ceramsite, ingasetyenziswa kakhulu kwizixhobo zokwakha, ukulima izityalo, ukutya neziselo, izixhobo zokufakelwa kwe-refractory, ishishini leekhemikhali, i-petroleum kunye namanye amacandelo. Ekuqaleni kokuyilwa nokuveliswa kwe-ceramsite, yayisetyenziswa kakhulu kwicandelo lezixhobo zokwakha. Ngenxa yophuhliso oluqhubekayo lwetekhnoloji kunye nokuqonda okunzulu kwabantu malunga neempawu ze-ceramsite, ukusetyenziswa kwe-ceramsite sele kudlule umda wendabuko wezixhobo zokwakha, kwaye ukusetyenziswa kwayo kuye kwanda ngokuqhubekayo. Ngoku ukusetyenziswa kwe-ceramsite kwizixhobo zokwakha kwehle ukusuka kwi-100% ukuya kwi-80%, kwaye ukusetyenziswa kwezinye iinkalo kuye kwabalelwa kwi-20%. Ngophuhliso oluqhubekayo lokusetyenziswa okutsha kwe-ceramsite, umlinganiselo wayo kwezinye iinkalo uya kwanda kancinci kancinci.
Iimpawu ze-fly ash ceramsite
Isizathu sokuba i-fly ash ceramsite ikhule ngokukhawuleza kwihlabathi liphela kukuba ineempawu ezininzi ezintle ezingenazo ezinye izinto. Le mpawu ibalaseleyo yenza ukuba ingathathelwa indawo zezinye izinto. Ezi mpawu zibalaseleyo zinezi zinto zilandelayo.
1. Ubunzima obuphantsi kunye nobunzima obulula. Ubunzima obukhulu be-fly ash ceramsite ngokwayo bungaphantsi kwe-1100kg/m3, ngokubanzi yi-300-900kg/m3. Ubunzima bekhonkrithi eyenziwe nge-fly ash ceramsite njenge-aggregate yi-1100-1800kg/m3, kwaye amandla oxinzelelo lwekhonkrithi ahambelanayo yi-30.5-40.0Mpa. Uphawu olukhulu lwe-ceramsite kukuba iqinile ngaphandle, kwaye kukho ii-micropores ezininzi ngaphakathi. Ezi micropores zinika i-ceramsite iipropati zayo zobunzima obuphantsi. Ubunzima bekhonkrithi ye-fly ash ceramsite enguNombolo 200 bumalunga ne-1600kg/m3, ngelixa ubuninzi bekhonkrithi eqhelekileyo eneleyibhile efanayo buphezulu njenge-2600kg/m3, kwaye umahluko phakathi kwezi zimbini yi-1000kg/m3.
2. Ukufakwa kwe-insulation kunye nokufakwa kwe-heat insulation. Ngenxa yengaphakathi layo elinomoya ovulekileyo, i-fly ash ceramsite ineempawu ezilungileyo zokufakwa kwe-thermal insulation. Ukuhanjiswa kwe-thermal kwekhonkrithi elungiselelwe ngayo ngokubanzi yi-0.3 ukuya kwi-0.8 W/(m·k), ephantsi ngokuphindwe ka-1 ukuya kwezi-2 kunekhonkrithi eqhelekileyo. Ke ngoko, izakhiwo ze-ceramsite zinendawo efanelekileyo yokusetyenziswa kwe-thermal.
3. Ukumelana kakuhle nomlilo, i-ceramsite inokumelana okuhle nomlilo. I-concrete eqhelekileyo ye-fly ash ceramsite okanye i-fly ash ceramsite block idibanisa ubushushu, ukumelana nenyikima, ukumelana neqabaka, ukumelana nomlilo kunye nezinye iimpawu, ingakumbi ukumelana nomlilo kungaphezulu kwe-4 kunekhonkrithi eqhelekileyo. Kwixesha elifanayo lokuchasana, ubukhulu bekhonkrithi ye-ceramsite buncinci ngama-20% kunobo bekhonkrithi eqhelekileyo. Ukongeza, i-fly ash ceramsite inokwenza ikhonkrithi echasanayo ene-refractoriness engaphantsi kwe-1200℃. Kubushushu obuphezulu be-650 ° C, ikhonkrithi ye-ceramsite inokugcina i-85% yamandla kubushushu begumbi. Ikhonkrithi eqhelekileyo inokugcina kuphela i-35% ukuya kwi-75% yamandla ayo kubushushu begumbi.
4. Ukusebenza kakuhle kwe-seismic. Ikhonkrithi ye-ceramsite inamandla amahle e-seismic ngenxa yobunzima bayo obulula, i-modulus ephantsi ye-elastic kunye nokumelana okuhle kwe-deformation.
5. Ukufunxwa kwamanzi kancinci, ukumelana kakuhle neqabaka kunye nokuqina. Ukusebenza kwekhonkrithi ye-ceramsite nge-asidi, i-alkali corrosion kunye nokumelana neqabaka kungcono kunekhonkrithi eqhelekileyo. Kwikhonkrithi ye-ceramsite ye-fly ash enguNombolo 250, ukulahleka kwamandla kwimijikelo yokuqandisa eyi-15 akudluli kwi-2%. Ikhonkrithi ye-ceramsite sisixhobo sokwakha esibalaseleyo kwaye kufuneka sikhuthazwe kwaye sisetyenziswe ngamandla.
