Kuyini i-Fly ash ceramsite?

Umlotha ondizayo I-ceramsite yenziwe ngomlotha wempukane njengento eluhlaza eyinhloko (cishe u-85%), ixutshwe nenani elifanele le-lime (noma i-calcium carbide slag), i-gypsum, izingxube, njll. I-aggregate elula yokwenziwa eyenziwe ngokusabela kwemvelo kwe-hydraulic. I-Ceramsite inezakhiwo ezinhle kakhulu, njengokuqina okuphansi, amandla aphezulu okucindezela isilinda, ukugoba okuphezulu, i-coefficient ephezulu yokuthambisa, ukumelana okuhle kweqhwa, kanye ne-reactivity enhle kakhulu ye-aggregate engamelana ne-alkali. Ikakhulukazi ngenxa yokuqina okuphansi kwe-ceramsite, ukugoba kwangaphakathi, ukuma okufanayo nokwakheka, kanye namandla athile nokuqina, inezinzuzo zesisindo esilula, ukumelana nokugqwala, ukumelana neqhwa, ukumelana nokuzamazama komhlaba kanye nokuvikela okuhle (ukulondolozwa kokushisa, ukuvikela ukushisa, ukuvikela umsindo, ukuvikela ukushisa, njll.) kanye nezinye izici eziningi. Isebenzisa lezi zakhiwo ezinhle kakhulu ze-ceramsite, ingasetshenziswa kabanzi ezintweni zokwakha, ukulima, ukudla neziphuzo, izinto zokuvikela eziphikisayo, imboni yamakhemikhali, uphethiloli kanye neminye imikhakha. Ekuqaleni kokusungulwa nokukhiqizwa kwe-ceramsite, yayisetshenziswa kakhulu emkhakheni wezinto zokwakha. Ngenxa yentuthuko eqhubekayo yobuchwepheshe kanye nokuqonda okujulile kwabantu ngezakhiwo ze-ceramsite, ukusetshenziswa kwe-ceramsite sekudlule ububanzi bendabuko bezinto zokwakha, futhi ukusetshenziswa kwayo kuye kwanda njalo. Manje ukusetshenziswa kwe-ceramsite ezintweni zokwakha kwehle kusuka ku-100% kuya ku-80%, kanti ukusetshenziswa kwezinye izici kuye kwabalelwa ku-20%. Ngokuthuthuka okuqhubekayo kokusetshenziswa okusha kwe-ceramsite, isilinganiso sayo kwezinye izici sizokhula kancane kancane.

Izakhiwo ze-ceramsite yomlotha ompukane

Isizathu sokuthi i-fly ash ceramsite ikhule ngokushesha emhlabeni wonke ukuthi inezakhiwo eziningi ezinhle kakhulu ezingenazo ezinye izinto. Le mpahla enhle kakhulu yenza ukuthi ingathathelwa indawo ezinye izinto. Lezi zakhiwo ezinhle kakhulu zinezici ezilandelayo.
1. Ubuningi obuphansi kanye nesisindo esincane. Ubuningi be-fly ash ceramsite ngokwayo bungaphansi kuka-1100kg/m3, ngokuvamile 300-900kg/m3. Ubuningi bekhonkrithi eyenziwe nge-fly ash ceramsite njenge-aggregate bungu-1100-1800kg/m3, kanti amandla okucindezela ekhonkrithi ahambisanayo angu-30.5-40.0Mpa. Isici esikhulu se-ceramsite ukuthi iqinile ngaphandle, futhi kunezimbobo eziningi ngaphakathi. Lawa ma-micropores anika i-ceramsite izakhiwo zayo ezilula. Ubuningi bekhonkrithi ye-fly ash ceramsite engu-No. 200 bungu-1600kg/m3, kanti ubuningi bekhonkrithi evamile enelebula elifanayo buphakeme njengo-2600kg/m3, kanti umehluko phakathi kwalokhu okubili ngu-1000kg/m3.
2. Ukuvikela ukushisa kanye nokuvikela ukushisa. Ngenxa yengaphakathi layo elinezimbobo, i-fly ash ceramsite inezakhiwo ezinhle zokuvikela ukushisa. Ukushisa kwekhonkrithi elungiselelwe ngayo ngokuvamile kungama-0.3 kuya ku-0.8 W/(m·k), okuphansi ngokuphindwe kabili kunokhonkrithi ojwayelekile. Ngakho-ke, izakhiwo ze-ceramsite zinendawo enhle yokushisa.
3. Ukumelana okuhle nomlilo, i-ceramsite inokumelana okuhle nomlilo. I-concrete evamile ye-ceramsite yomlotha wempukane noma i-fly ash ceramsite block ihlanganisa ukufudumala, ukumelana nokuzamazama komhlaba, ukumelana nesithwathwa, ukumelana nomlilo nezinye izakhiwo, ikakhulukazi ukumelana nomlilo kungaphezu kokuphindwe kane kunokhonkolo ojwayelekile. Esikhathini esifanayo sokungaguquguquki, ubukhulu bekhonkrithi ye-ceramsite buncane ngo-20% kunokhonkolo ojwayelekile. Ngaphezu kwalokho, i-ceramsite yomlotha wempukane ingalungisa futhi ikhonkrithi yokungaguquguquki engaphansi kuka-1200℃. Ekushiseni okuphezulu okungu-650 ° C, ikhonkrithi ye-ceramsite ingagcina u-85% wamandla ekushiseni kwegumbi. Ikhonkrithi evamile ingagcina u-35% kuya ku-75% wamandla ayo ekushiseni kwegumbi.
4. Ukusebenza kahle kokuzamazama komhlaba. Ikhonkrithi ye-Ceramsite isebenza kahle kokuzamazama komhlaba ngenxa yesisindo sayo esilula, i-modulus ephansi yokunwebeka kanye nokumelana okuhle kokuguquguquka komhlaba.
5. Ukumuncwa kwamanzi okuphansi, ukumelana okuhle nokuqandisa kanye nokuqina. Ukusebenza kwekhonkrithi ye-ceramsite okune-asidi, ukugqwala kwe-alkali kanye nokumelana nokuqandisa kungcono kunokwekhonkrithi evamile. Kukhonkrithi ye-ceramsite enguNombolo 250 ye-fly ash, ukulahlekelwa amandla kwemijikelezo engu-15 yokuqandisa akudluli ku-2%. Ikhonkrithi ye-ceramsite iyinto yokwakha enhle kakhulu futhi kufanele ikhuthazwe futhi isetshenziswe ngamandla.
