isicelo yesivini

Foam ukhonkolo, eyaziwa nangokuthi aircrete, ukhonkolo foamed, foamcrete, yeselula ukhonkolo engasindi noma encishisiwe ukuminyana ukhonkolo, uchazwa ngokuthi slurry usimende based, okungenani u-20% (ngayinye umthamo) Foam entrained ku nosimende plastic. [1] Njengoba ikakhulukazi akukho aggregate indawo isetshenziselwa ukukhiqiza Foam ukhonkolo igama ekungilo yayiyobizwa ngokuthi nosimende esikhundleni aphathekako; ke kusengathiwa "usimende foamed" kanye. I kwabantu of Foam ukhonkolo ngokuvamile kuhluka 400 kg / m³ ukuba 1600 kg / m³. I kwabantu ngokuvamile ilawulwa abambele ngokugcwele noma ingxenye aggregate esihle amagwebu.

Ukukhiqiza

ukhonkolo Foamed ngokuvamile siqukethe slurry kasimende futhi fly umlotha noma isihlabathi namanzi, nakuba abanye abahlinzeki ukuncoma usimende namanzi okuhlanzekile ne-ejenti yesivini for amamiksi engasindi kakhulu. Lokhu slurry kuyinto okwengeziwe ixutshwe zokwenziwa Foam evundile e ukhonkolo kuhlangana isitshalo. I kephunkephu idalwe kusetshenziswa i-ejenti yesivini, luhlanganiswa namanzi bese emoyeni kusukela generator. I-ejenti yesivini esetshenziswa kumele akwazi ukukhiqiza air Bubbles nge ezingeni lelisetulu ukuzinza, amelana izinqubo zemvelo namakhemikhali yokuhlanganisa, ukubeka lukhuni.

 

Foamed ingxube ukhonkolo kungenzeka wathela noma akhishwa phakathi isikhunta, noma ngqo timphawu tesakhiwo. I Foam kwenza slurry umongozima ngokukhululekile ngenxa yokuziphatha thixotropic we Bubbles Foam, silivumele libe kalula batheleka ifomu ekhethiwe noma mould.The impahla viscous kudinga amahora angu-24 yokuzigxilisa (kancane noma amahora amabili uma umusi belashwa nge okushisa afinyelela ku-70 ° C * kunonophisa luhlelo.), kuncike eziguquguqukayo kubandakanya kuma lokushisa kanye nomswakama. Uma eqina, umkhiqizo kwakhiwa kungenzeka adedelwe ngenkani efolomeni lalo.

izicelo

Ukhonkolo Foamed zingaba nge nokuminyanisa ezomile 400 kuya 1600 kg / m³, ne ezingu-7 uyabaqinisa cishe 1 kuya ku-10 N / mm² ngokulandelana. Foam ukhonkolo umlilo nemithi, futhi ezishisayo kanye acoustical ukwahlukanisa impahla yayo ukwenza kube ekahle tinhlobo letibanti letehlukene tetinhloso, kusukela nangokuvikela izibuya nophahla, ukuze kupheze ukugcwaliswa. Libuye esiwusizo ngokukhethekile emseleni Ukubuyiselwa.
Amalungu ambalwa kwamaningi izicelo Foam ukhonkolo yilezi:
amabhlogo Precast
Precast izakhi odongeni / panel
waphonsa-e-situ / ezinikwe ku-indawo izindonga
nangokuvikela isinxephezelo laying
ukwahlukanisa phansi screeds
ukwahlukanisa uphahla screeds
ingxenye lushone ngokugcwalisa
emseleni Ukubuyiselwa
sub-ayehlala kuwo lapho ekuleso othelawayeka
ngokugcwalisa ka amabhlogo ozwakala
prefabricated ukwahlukanisa amabhodi

Izakhiwo

Foam ukhonkolo enemisebenzi zokwakha nge indlela elula ukukhiqiza ukuthi ayibizi kuqhathaniswa autoclave ukhonkolo evundile. Foam compounds ukhonkolo sisebenzisa impukane umlotha e ukuxubana slurry ushibhile namanje, futhi kancane nomthelela wendawo ezungezile kubantu. Foam ukhonkolo ikhiqizwa ezihlukahlukene nokuminyanisa kusuka 200 kg / m³ ukuba 1600 kg / m³ kuye isicelo. imikhiqizo Lighter kwabantu kungase uthathe letingemasayizi lahlukene. Nakuba umkhiqizo kubhekwa ifomu ngokhonkolo (nge air Bubbles esikhundleni aggregate), izimfanelo zawo okusezingeni eliphezulu ezishisayo kanye acoustical nangokuvikela ukwenza kube isicelo ezahlukene kakhulu ukwedlula ukhonkolo ezivamile.

Amathrendi wakamuva nokuthuthukiswa

Kuze eyishumi edlule, igwebu ukhonkolo iye uthathwa njengoba ababuthakathaka futhi okungezona eliqinile le nge high ukuncipha izici. Lokhu kungenxa engazinzile Foam Bubbles kuholele Foam ukhonkolo kokuba izakhiwo engafanele esikhiqiza kwabantu aphansi kakhulu (Ngaphansi kuka 300 kg / m³ ukuminyana ezomile) kanye umthwalo ebizwa izicelo kwesakhiwo. Ngakho-ke kubalulekile ukuqinisekisa ukuthi umoya entrained ku ukhonkolo foamed kuqukethwe esitebeleni ngesikhathi esifanayo Amagwebu kakhulu iyunifomu ukuthi bunjalo futhi elahliwe futhi musa kanjalo zandise permeability we unamathisele usimende phakathi imigodi.

Ukuthuthukiswa zokwenziwa-enzyme based yesivini ejenti, igwebu ukuzinza ekuthuthukiseni admixtures futhi ezikhethekile Foam ugcogce, ukuxuba futhi uzotshala imishini iye yathuthuka ukuzinza Foam futhi ngalesosizathu foam ukhonkolo, okwenza kube lula okwenza njengoba ukukhanya njengoba 75 kg / m³ density.The enzyme siqukethe amaprotheni kakhulu asebenzayo Lokudabuka biotechnological futhi awusekelwe amaprotheni alithandeki hydrolysis.In eminyakeni yamuva ukhonkolo foamed iye yasetshenziswa kakhulu emikhulu, izakhiwo kwezohwebo, inhlekelele nokuvuselelwa izakhiwo, izikole, amafulethi zokwakhiwa kwezindlu emazweni anjenge Germany, USA, Brazil, eSingapore, eNdiya, Malaysia, Kuwait, Nigeria, Botswana, eMexico, e-Indonesia, Libya, Saudi Arabia, Algeria, e-Iraq neGibhithe.
