He aha ka Fly ash ceramsite?

Lehu lele Hana ʻia ka ceramsite me ka lehu lele ma ke ʻano he mea maka nui (ma kahi o 85%), i kāwili ʻia me ka nui kūpono o ka lime (a i ʻole ka calcium carbide slag), gypsum, nā mea hoʻohui, a pēlā aku. He ʻāpana māmā hana i hana ʻia mai ka hopena hydraulic kūlohelohe. Loaʻa iā Ceramsite nā waiwai maikaʻi loa, e like me ka haʻahaʻa haʻahaʻa, ka ikaika compressive cylinder kiʻekiʻe, ka porosity kiʻekiʻe, ke koina palupalu kiʻekiʻe, ke kūpaʻa hau maikaʻi, a me ka reactivity aggregate alkali-resistant maikaʻi loa. ʻOi loa ma muli o ka haʻahaʻa haʻahaʻa o ka ceramsite, ka porousness kūloko, ke ʻano like a me ka haku mele ʻana, a me kekahi ikaika a me ka paʻa, loaʻa iā ia nā pono o ke kaumaha māmā, ke kūpaʻa i ka corrosion, ke kūpaʻa i ka hau, ke kūpaʻa i ka ōlaʻi a me ka insulation maikaʻi (mālama wela, insulation wela, insulation leo, insulation, etc.). tide) a me nā hiʻohiʻona multifunctional ʻē aʻe. Me ka hoʻohana ʻana i kēia mau waiwai maikaʻi loa o ka ceramsite, hiki ke hoʻohana nui ʻia i nā mea kūkulu hale, nā māla, nā meaʻai a me nā mea inu, nā mea insulation refractory, ka ʻoihana kemika, ka petroleum a me nā ʻāpana ʻē aʻe. I ka hoʻomaka ʻana o ka hana ʻana a me ka hana ʻana o ka ceramsite, ua hoʻohana nui ʻia ia ma ke kahua o nā mea kūkulu hale. Ma muli o ka hoʻomohala mau ʻana o ka ʻenehana a me ka ʻike hohonu o ka poʻe i nā waiwai o ka ceramsite, ua ʻoi aku ka nui o ka hoʻohana ʻana o ka ceramsite ma mua o ka laulā kuʻuna o nā mea kūkulu hale, a ua hoʻonui mau ʻia kāna noi. kahua. I kēia manawa ua hāʻule ka hoʻohana ʻana o ka ceramsite i nā mea kūkulu hale mai 100% a i 80%, a ua helu ʻia ka hoʻohana ʻana ma nā ʻano ʻē aʻe no 20%. Me ka hoʻomohala mau ʻana o nā hoʻohana hou o ka ceramsite, e piʻi mālie kona hapa ma nā ʻano ʻē aʻe.

Nā waiwai o ka lehu lele ceramsite

ʻO ke kumu i ulu wikiwiki ai ka lehu lele ceramsite ma ka honua holoʻokoʻa, ʻo ia ka nui o nā waiwai maikaʻi loa i loaʻa ʻole i nā mea ʻē aʻe. ʻO kēia waiwai maikaʻi loa e hiki ʻole ai ke pani ʻia e nā mea ʻē aʻe. Loaʻa i kēia mau waiwai maikaʻi nā ʻano aʻe.
1. Haʻahaʻa ka nui a me ke kaumaha māmā. ʻO ka nui o ka nui o ka lehu lele ceramsite ponoʻī he emi ma mua o 1100kg/m3, ma ke ʻano maʻamau he 300-900kg/m3. ʻO ka nui o ka sima i hana ʻia me ka lehu lele ceramsite ma ke ʻano he aggregate he 1100-1800kg/m3, a ʻo ka ikaika compressive sima e pili ana he 30.5-40.0Mpa. ʻO ka hiʻohiʻona nui o ka ceramsite, ʻo ia ka paʻakikī ma waho, a he nui nā micropores i loko. Hāʻawi kēia mau micropores i ka ceramsite i kona mau waiwai māmā. ʻO ka nui o ka sima lehu lele No. 200 ma kahi o 1600kg/m3, ʻoiai ʻo ka nui o ka sima maʻamau me ka lepili like he kiʻekiʻe e like me 2600kg/m3, a ʻo ka ʻokoʻa ma waena o nā mea ʻelua he 1000kg/m3.
2. Ka pale ʻana a me ka pale wela. Ma muli o kona ʻano porous o loko, loaʻa i ka ceramsite lehu lele nā ​​​​​​waiwai pale wela maikaʻi. ʻO ka conductivity wela o ka sima i hoʻomākaukau ʻia me ia he 0.3 a 0.8 W/(m·k), ʻo ia hoʻi he 1 a 2 mau manawa haʻahaʻa ma mua o ka sima maʻamau. No laila, he maikaʻi ke kaiapuni wela o nā hale ceramsite.
3. Kūpaʻa maikaʻi i ke ahi, loaʻa i ka ceramsite ke kūpaʻa ahi maikaʻi loa. Hoʻohui ka sima ceramsite lehu lele maʻamau a i ʻole ka poloka ceramsite lehu lele i ka insulation thermal, ke kūpaʻa ʻōlaʻi, ke kūpaʻa hau, ke kūpaʻa ahi a me nā waiwai ʻē aʻe, ʻoi aku ka pale ʻana i ke ahi ma mua o 4 mau manawa o ka sima maʻamau. No ka manawa refractory like, ʻoi aku ka lahilahi o ka mānoanoa o ka sima ceramsite he 20% ma mua o ka sima maʻamau. Eia kekahi, hiki i ka ceramsite lehu lele ke hoʻomākaukau i ka sima refractory me ka refractoriness ma lalo o 1200 ℃. I ke kiʻekiʻe o ka mahana o 650 ° C, hiki i ka sima ceramsite ke mālama i 85% o ka ikaika ma ka mahana o ka lumi. Hiki i ka sima maʻamau ke mālama i 35% a 75% o kona ikaika ma ka mahana o ka lumi.
4. Hana seismic maikaʻi. He hana seismic maikaʻi ka sima Ceramsite ma muli o kona māmā, modulus elastic haʻahaʻa a me ke kūpaʻa deformation maikaʻi.
5. Haʻahaʻa ka omo ʻana o ka wai, maikaʻi ke kūpaʻa i ka hau a me ke kūpaʻa. ʻOi aku ka maikaʻi o ka hana kūpaʻa waikawa, alkali a me ka hau o ka sima ceramsite ma mua o ka sima maʻamau. No ka sima ceramsite lele lehu No. 250, ʻaʻole ʻoi aku ka pohō ikaika o 15 mau pōʻaiapuni hau-hoʻoheheʻe ma mua o 2%. He mea kūkulu hale maikaʻi loa ka sima ceramsite a pono e hoʻolaha ikaika ʻia a hoʻohana ʻia.
