He aha ka Fly ash ceramsite?

Lehu leleHana ʻia ka ceramsite i ka lehu lele ma ke ʻano he kumu maka nui (ma kahi o 85%), i hui pū ʻia me ka nui o ka lime (a i ʻole calcium carbide slag), gypsum, admixtures, etc.Loaʻa i ka Ceramsite nā waiwai maikaʻi loa, e like me ka haʻahaʻa haʻahaʻa, kiʻekiʻe cylinder compressive ikaika, kiʻekiʻe porosity, kiʻekiʻe softening coefficient, maikaʻi hau kū'ē, a me ka maikaʻi alkali-kū'ē aggregate reactivity.Ma muli o ka haʻahaʻa haʻahaʻa o ka ceramsite, ka porousness o loko, ke ʻano like ʻole a me ka haku mele ʻana, a me kekahi ikaika a me ka paʻa, loaʻa iā ia nā pōmaikaʻi o ke kaumaha māmā, ka pale ʻana i ka corrosion, ke kūpaʻa hau, ke kū ʻana o ke ōlaʻi a me ka insulation maikaʻi (mālama wela, wela. ka hoʻokuʻu ʻana, ka hoʻopaʻa ʻana i ke kani, ka hoʻopaʻa ʻana, etc.).tide) a me nā hiʻohiʻona multifunctional ʻē aʻe.Ke hoʻohana nei i kēia mau waiwai maikaʻi o ka ceramsite, hiki ke hoʻohana nui ʻia i nā mea kūkulu hale, horticulture, meaʻai a me nā mea inu, refractory insulation material, ʻoihana kemika, 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 i ke kahua o nā mea kūkulu hale.Ma muli o ka hoʻomau mau ʻana o ka ʻenehana a me ka ʻike hohonu o ka poʻe i nā waiwai o ka ceramsite, ua ʻoi aku ka hoʻohana ʻana o ka ceramsite ma mua o ka pae kuʻuna o nā mea kūkulu hale, a ua hoʻonui mau ʻia kāna noi.kahua.I kēia manawa ua hāʻule ka noi ʻana o ka ceramsite i nā mea kūkulu hale mai 100% a i 80%, a ʻo ka noi ʻana i nā mea ʻē aʻe i helu ʻia no 20%.Me ka hoʻomau mau ʻana o ka hoʻohana hou ʻana i ka ceramsite, e piʻi mālie kona ʻāpana i nā ʻano ʻē aʻe.

Nā waiwai o ka lele lehu ceramsite

ʻO ke kumu i ulu wikiwiki ai ka fly ash ceramsite ma ka honua holoʻokoʻa he nui nā waiwai maikaʻi i loaʻa ʻole i nā mea ʻē aʻe.ʻO kēia waiwai maikaʻi e hikiʻole ke hoʻololiʻia e nā mea'ē aʻe.Loaʻa i kēia mau waiwai maikaʻi kēia mau ʻano.
1. Haʻahaʻa haʻahaʻa a me ke kaumaha māmā.ʻO ka nui nui o ka lele lehu ceramsite iho ma lalo o 1100kg / m3, maʻamau 300-900kg / m3.ʻO ka mānoanoa o ke kaʻa i hana ʻia me ka lele lehu ceramsite e like me ka aggregate he 1100-1800kg/m3, a ʻo ka ikaika compressive paʻa like ʻo 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 kāna mau waiwai māmā.He 1600kg/m3 ka mānoanoa o ka No. 200 lele lehu ceramsite, oiai ke kiʻekiʻe o ka pāpaʻi maʻamau me ka lepili like me 2600kg/m3, a ʻo ka ʻokoʻa ma waena o nā mea ʻelua he 1000kg/m3.
2. Hoʻopili a me ka wela wela.Ma muli o kona porous i loko, lele ka lehu ceramsite he maikaʻi nā waiwai insulation thermal.ʻO ka maʻamau o ka conductivity thermal o ke koʻi i hoʻomākaukau ʻia me ia ma ke ʻano maʻamau he 0.3 a i ka 0.8 W/(m·k), ʻo ia ka 1 a 2 mau manawa haʻahaʻa ma mua o ko ka lāʻau maʻamau.No laila, he wahi wela maikaʻi nā hale ceramsite.
3. ʻO ke ahi maikaʻi maikaʻi, ʻoi aku ka maikaʻi o ka ceramsite.ʻO ka lele lehu ceramsite maʻamau a i ʻole ka lele lehu ceramsite poloka e hoʻohui i ka insulation thermal, ke kū ʻana o ke ōlaʻi, ke kūpaʻa hau, ke kūpaʻa ahi a me nā waiwai ʻē aʻe, ʻoi aku ka ʻoi aku o ka pale ʻana i ke ahi ma mua o 4 mau manawa ma mua o ka paʻa maʻamau.No ka manawa refractory like, ʻoi aku ka lahilahi o ka mānoanoa o ka ceramsite concrete he 20% ʻoi aku ka ʻoi aku o ka ʻoi aku o ka ʻoi aku ka maʻamau.Eia kekahi, hiki i ka lele lehu ceramsite ke hoʻomākaukau i ka pahu refractory me ka refractoriness ma lalo o 1200 ℃.Ma kahi mahana kiʻekiʻe o 650 ° C, hiki i ka ceramsite concrete ke mālama i ka 85% o ka ikaika ma ke ana wela.Hiki ke mālama wale i ka 35% a i ka 75% o kona ikaika ma ka mahana wela o ka lumi.
4. Maikaʻi ka hana seismic.He maikaʻi ka hana seismic Ceramsite ma muli o kona kaumaha māmā, modulus elastic haʻahaʻa a me ke kūpaʻa deformation maikaʻi.
5. Haʻahaʻa wai absorption, hau maikaʻi kū'ē a me ka lōʻihi.ʻOi aku ka maikaʻi o ka ʻakika, alkali corrosion a me ka hau kūʻē ʻana o ka ceramsite concrete ma mua o ka hana maʻamau.No ka helu 250 lele lehu ceramsite concrete, ʻaʻole i ʻoi aku ka ikaika o ka pohō o 15 freeze-thaw cycles ma mua o 2%.ʻO Ceramsite concrete kahi mea kūkulu hale maikaʻi loa a pono e hoʻoikaika a hoʻohana ikaika ʻia.
