Iyini i-Fly ash ceramsite?

Fly umlotha I-ceramsite yenziwe ngomlotha wezimpukane njengento eluhlaza eyinhloko (cishe u-85%), exutshwe nenani elifanele lomcako (noma i-calcium carbide slag), i-gypsum, izixube, njll. I-aggregate yokwenziwa engasindi eyenziwe ngokusabela kwehydraulic yemvelo. I-Ceramsite inezinto ezinhle kakhulu, ezifana nokuminyana okuphansi, amandla okucindezela isilinda aphezulu, i-porosity ephezulu, i-coefficient yokuthambisa okuphezulu, ukumelana nesithwathwa okuhle, kanye nokusebenza okuhle kakhulu kwe-alkali-resistant aggregate. Ikakhulukazi ngenxa yokuminyana okuphansi kwe-ceramsite, i-porousness yangaphakathi, ukwakheka okufanayo kanye nokwakheka, namandla athile nokuqina, inezinzuzo zesisindo esilula, ukumelana nokugqwala, ukumelana nesithwathwa, ukumelana nokuzamazama komhlaba kanye nokufakwa kahle (ukugcina ukushisa, ukushisa. i-insulation, i-sound insulation, i-insulation, njll.). tide) nezinye izici ezisebenzayo. Isebenzisa lezi zakhiwo ezinhle kakhulu ze-ceramsite, ingasetshenziswa kabanzi ezintweni zokwakha, ukulima, ukudla nesiphuzo, izinto zokufaka eziphikisayo, imboni yamakhemikhali, i-petroleum neminye imikhakha. Ekuqaleni kokusungulwa nokukhiqizwa kwe-ceramsite, yayisetshenziswa ikakhulukazi emkhakheni wezinto zokwakha. Ngenxa yokuthuthukiswa okuqhubekayo kobuchwepheshe kanye nokuqonda okujulile kwabantu kwezakhiwo ze-ceramsite, ukusetshenziswa kwe-ceramsite sekuvele kudlule ububanzi bendabuko bezinto zokwakha, futhi ukusetshenziswa kwayo kuye kwandiswa ngokuqhubekayo. inkambu. Manje ukusetshenziswa kwe-ceramsite ezintweni zokwakha kwehlile kusuka ku-100% kuya ku-80%, futhi isicelo kwezinye izici sibalwa ngama-20%. Ngokuthuthuka okuqhubekayo kokusetshenziswa okusha kwe-ceramsite, ingxenye yayo kwezinye izici izokhula kancane kancane.

Izakhiwo ze-fly ash ceramsite

Isizathu esenza ukuthi i-fly ash ceramsite ithuthuke ngokushesha emhlabeni wonke ukuthi inezinto eziningi ezinhle kakhulu ezinye izinto ezingenazo. Lesi sakhiwo esihle kakhulu sikwenza kungenakushintshwa ezinye izinto. Lezi zakhiwo ezinhle kakhulu zinezici ezilandelayo.
1. Ukuminyana okuphansi nesisindo esincane. Ukuminyana kwenqwaba ye-fly ash ceramsite ngokwayo kungaphansi kuka-1100kg/m3, ngokuvamile ku-300-900kg/m3. Ukuminyana kukakhonkolo owenziwe nge-fly ash ceramsite njenge-aggregate ngu-1100-1800kg/m3, futhi amandla okucindezela kakhonkolo ahambisanayo angu-30.5-40.0Mpa. Isici esikhulu kunazo zonke se-ceramsite ukuthi sinzima ngaphandle, futhi kukhona ama-micropores amaningi ngaphakathi. Lawa ma-micropores anikeza i-ceramsite izakhiwo zayo ezinesisindo esincane. Ukuminyana kukakhonkolo we-fly ash ceramsite No.
2. Insulation kanye nokushisa ukushisa. Ngenxa yengaphakathi layo elinezimbotshana, i-fly ash ceramsite inezindawo ezinhle zokuvala ukushisa. I-conductivity eshisayo yekhonkrithi elungiselelwe nayo ngokuvamile i-0.3 kuya ku-0.8 W / (m·k), okuyizikhathi ezi-1 kuya kwezi-2 eziphansi kunokhonkolo ovamile. Ngakho-ke, izakhiwo ze-ceramsite zinendawo enhle yokushisa.
3. Ukumelana nomlilo okuhle, i-ceramsite inokumelana nomlilo okuhle kakhulu. Ukhonkolo ojwayelekile we-fly ash ceramsite noma i-fly ash ceramsite block ihlanganisa ukufakwa okushisayo, ukumelana nokuzamazama komhlaba, ukumelana nesithwathwa, ukumelana nomlilo nezinye izakhiwo, ikakhulukazi ukumelana nomlilo kungaphezu kwezikhathi ezi-4 zokhonkolo ojwayelekile. Ngesikhathi esifanayo sokuphikisa, ubukhulu bokhonkolo be-ceramsite buncane ngo-20% kunokhonkolo ovamile. Ngaphezu kwalokho, i-fly ash ceramsite nayo ingalungisa ukhonkolo ophikisayo one-refractoriness engaphansi kuka-1200 ℃. Ekushiseni okuphezulu kuka-650 ° C, ukhonkolo we-ceramsite ungagcina u-85% wamandla ekamelweni lokushisa. Ukhonkolo ovamile ungagcina kuphela u-35% kuya ku-75% wamandla awo endaweni yokushisa.
4. Ukusebenza okuhle kokuzamazama komhlaba. Ukhonkolo we-Ceramsite unokusebenza okuhle kokuzamazama komhlaba ngenxa yesisindo sawo esilula, i-modulus ephansi enwebekayo kanye nokumelana okuhle nokuguquguquka.
5. Ukumuncwa kwamanzi aphansi, ukumelana nesithwathwa okuhle nokuqina. I-asidi, ukugqwala kwe-alkali kanye nokusebenza kokumelana nesithwathwa kukakhonkolo we-ceramsite kungcono kunokhonkolo ojwayelekile. Ku-No. Ukhonkolo we-Ceramsite uyinto enhle kakhulu yokwakha futhi kufanele ikhuthazwe futhi isetshenziswe ngamandla.
