Kodi Fly ash ceramsite ndi chiyani?

Thirani phulusa ceramsite amapangidwa ndi ntchentche phulusa monga waukulu zopangira (pafupifupi 85%), wothira kuchuluka koyenera laimu (kapena kashiamu carbide slag), gypsum, admixtures, etc. An yokumba opepuka aggregate opangidwa kuchokera zachilengedwe hayidiroliki anachita. Ceramsite ili ndi zinthu zabwino kwambiri, monga kachulukidwe kakang'ono, mphamvu yopondereza ya silinda yayikulu, porosity yayikulu, kufewetsa kwakukulu, kukana chisanu, ndikuchitanso bwino kwa alkali-resistant aggregate reactivity. Makamaka chifukwa otsika kachulukidwe ceramsite, porousness mkati, mawonekedwe yunifolomu ndi zikuchokera, ndi mphamvu zina ndi kulimba, ali ndi ubwino wopepuka kulemera, kukana dzimbiri, kukana chisanu, kukana zivomezi ndi kutchinjiriza bwino (kuteteza kutentha, kutentha). kutsekereza, kutsekereza mawu, kutsekereza, etc.). mafunde) ndi zina zambiri. Pogwiritsa ntchito zinthu zabwino kwambiri za ceramsite, zitha kugwiritsidwa ntchito kwambiri muzomangamanga, ulimi wamaluwa, chakudya ndi zakumwa, zida zotchinjiriza, zopangira mankhwala, mafuta amafuta ndi magawo ena. Kumayambiriro kwa kupangidwa ndi kupanga ceramsite, idagwiritsidwa ntchito makamaka popanga zida zomangira. Chifukwa chakukula kosalekeza kwaukadaulo komanso kumvetsetsa kwakuya kwa anthu pazinthu za ceramsite, kugwiritsa ntchito ceramsite kwadutsa kale kuchuluka kwa zida zomangira, ndipo kugwiritsa ntchito kwake kwakulitsidwa mosalekeza. munda. Tsopano kugwiritsa ntchito ceramsite muzomangamanga kwatsika kuchoka pa 100% mpaka 80%, ndipo kugwiritsa ntchito mbali zina kwawerengera 20%. Ndi kukula kosalekeza kwa ntchito zatsopano za ceramsite, gawo lake muzinthu zina lidzawonjezeka pang'onopang'ono.

Katundu wa ntchentche ash ceramsite

Chifukwa chomwe fly ash ceramsite yakula mwachangu padziko lonse lapansi ndikuti ili ndi zinthu zambiri zabwino zomwe zida zina zilibe. Katundu wabwino kwambiriyu amapangitsa kuti zisalowe m'malo ndi zida zina. Makhalidwe abwinowa ali ndi mbali zotsatirazi.
1. Kutsika kochepa komanso kulemera kochepa. Kachulukidwe kachulukidwe ka fly ash ceramsite palokha ndi ochepera 1100kg/m3, nthawi zambiri 300-900kg/m3. Kachulukidwe konkire wopangidwa ndi ntchentche phulusa ceramsite monga akaphatikiza ndi 1100-1800kg/m3, ndi lolingana konkire compressive mphamvu ndi 30.5-40.0Mpa. Mbali yaikulu ya ceramsite ndi yolimba kunja, ndipo pali ma micropores ambiri mkati. Ma micropores awa amapatsa ceramsite mawonekedwe ake opepuka. Kachulukidwe wa No. 200 ntchentche phulusa ceramsite konkire ndi za 1600kg/m3, pamene kachulukidwe wa konkire wamba ndi chizindikiro chomwecho ndi mkulu monga 2600kg/m3, ndi kusiyana awiri ndi 1000kg/m3.
2. Insulation ndi kutentha kutentha. Chifukwa cha mkati mwake muli porous, fly ash ceramsite ili ndi mphamvu zotetezera kutentha. The matenthedwe madutsidwe wa konkire wokonzedwa ndi nthawi zambiri 0,3 kuti 0.8 W/(m·k), amene ndi 1 kwa 2 kutsika kuposa konkire wamba. Choncho, nyumba za ceramsite zimakhala ndi malo abwino otentha.
3. Kukana moto wabwino, ceramsite ili ndi kukana moto kwabwino. Wamba ntchentche phulusa ceramsite konkire kapena ntchentche phulusa ceramsite chipika integrates kutchinjiriza matenthedwe, kukana chivomezi, kukana chisanu, kukana moto ndi katundu zina, makamaka kukana moto ndi kuposa 4 nthawi konkire wamba. Pa nthawi yomweyi yotsutsa, makulidwe a konkire ya ceramsite ndi 20% yowonda kuposa konkire wamba. Komanso, ntchentche phulusa ceramsite angathenso kukonzekera refractory konkire ndi refractoriness pansipa 1200 ℃. Pa kutentha kwakukulu kwa 650 ° C, konkire ya ceramsite imatha kusunga 85% ya mphamvu kutentha. Konkire wamba amatha kusunga 35% mpaka 75% ya mphamvu zake kutentha.
4. Kuchita bwino kwa seismic. Konkire ya Ceramsite imakhala ndi ntchito yabwino ya seismic chifukwa cha kulemera kwake, modulus yotsika komanso kukana kwabwino.
5. Mayamwidwe amadzi otsika, kukana kwachisanu kwabwino komanso kukhazikika. Asidi, dzimbiri za alkali ndi kukana chisanu kwa konkire ya ceramsite ndizabwinoko kuposa konkire wamba. Pakuti No. 250 ntchentche phulusa ceramsite konkire, kutaya mphamvu 15 amaundana-thaw m'zinthu si oposa 2%. Ceramsite konkire ndi nyumba yabwino kwambiri yomangira ndipo iyenera kulimbikitsidwa mwamphamvu ndikugwiritsidwa ntchito.
