thobvu ntchito

Thovu konkire, amatchedwanso aircrete, foamed konkire, foamcrete, ma opepuka simenti kapena yafupika kachulukidwe konkire, limanenedwa ngati simenti zochokera slurry, ndi osachepera 20% (pa buku) thovu entrained mu mtondo pulasitiki. [1] Monga makamaka palibe akaphatikiza coarse ntchito yopanga thovu konkire olondola akuti adzatchedwa matope m'malo konkire; kuti angatchedwe "foamed simenti" komanso. osalimba a thovu konkire zambiri zimasiyanasiyana makilogalamu 400 / m³ kwa 1600 makilogalamu / m³. kachulukidwe amakhala olamulidwa ndi m'malo mokwanira kapena mbali ya akaphatikiza chabwino ndi thovu.

opanga

Foamed konkire ambiri imakhala slurry simenti ndi kuuluka phulusa kapena mchenga ndi madzi, ngakhale ena ogulitsa amalangiza simenti woyera ndi madzi ndi wothandizila thobvu kwa kasakaniza opepuka kwambiri. slurry Ichi ndi zina wosanganiza ndi kupanga lokhala ndi mpweya wokwanira thovu mu konkire kusanganikirana mbewu. chithovu analengedwa ntchito wothandizila thobvu, wothira madzi ndi mpweya jenereta ndi. Nthumwi thobvu ntchito ayenera kupereka mpweya thovu ndi mkulu mlingo wa bata, kugonjetsedwa ndi njira thupi ndi mankhwala Kusakaniza, kuwayika ndi kuumitsa.

 

Foamed osakaniza konkire akhoza adzakhetsedwa kapena kupopa zisamere pachakudya kapena mwachindunji mu zinthu structural. Chithovu umathandiza slurry kuyenda momasuka chifukwa khalidwe thixotropic thovu chithovu, kuwalola kukhala mosavuta anazitsanulira mwa mawonekedwe osankhidwa kapena mould.The viscous chuma kumafuna maola 24 kuti alimbitse (kapena zochepa monga maola awiri ngati nthunzi adachiritsidwa ndi kutentha 70 ° C kwa imathandizira ndondomekoyi.), malingana zosintha kuphatikizapo yozungulira kutentha ndi chinyezi. Kamodzi Unalimbitsa, zipatso anapanga akhoza kumasulidwa ku nkhungu ake.

Mapulogalamu

Foamed konkire akhoza kupangidwa ndi machulukidwe wouma 400 1600 makilogalamu / m³, ndi masiku 7 mphamvu pafupifupi 1 10 N / mm² motero. Thovu mwala ndi moto amalimbana ndi matenthedwe ndi acoustical katundu kutchinjiriza kupanga izo abwino osiyanasiyana zolinga ku chimateteza Pansi ndi madenga, kuti achabe kudzazidwa. Komanso makamaka lipindulitsa pa ngalande abwezeretsedwe.
A angapo a ntchito thovu simenti ndi:
midadada precast
precast zinthu wall / mapanelo
kuponyedwa mu situ / osewera mu malo makoma
chimateteza malipilo atagona
kutchinjiriza pansi screeds
kutchinjiriza denga screeds
olowa gawo kudzaza
ngalande abwezeretsedwe
boma m'munsi mwa misewu
kudzaza wa midadada dzenje
zoduliratu kutchinjiriza matabwa

katundu

Thovu mwala ndi zosunthika zomangila ndi njira yopanga osavuta kuti zimakhalanso zotsika mtengo poyerekeza autoclave lokhala ndi mpweya wokwanira konkire. Thovu mankhwala konkire kugwiritsa ntchito ntchentche phulusa mu slurry Kusakaniza ndi yotsika, ndipo ali zochepa zingakhudzire chilengedwe. Thovu konkire amapangidwa zosiyanasiyana machulukidwe 200 makilogalamu / m³ kuti makilogalamu 1,600 / m³ malingana ntchito. Mbandakucha kachulukidwe mankhwala akhoza kusema zamitundu yosiyanasiyana. Ngakhale mankhwala imatengedwa mawonekedwe konkire (ndi mpweya thovu m'malo akaphatikiza), mkulu makhalidwe ake matenthedwe ndi acoustical chimateteza likhale ntchito zotsiyana ochiritsira konkire.

mumaganiza Recent ndi chitukuko

Mpaka zaka khumi zapitazo, thovu konkire wakhala ankamuona ngati ofooka ndipo sanali cholimba ndi makhalidwe mkulu shrinkage. Ichi ndi chifukwa kusokonekera thovu thovu zinachititsa thovu simenti ndi katundu zosafunika yopangira otsika kachulukidwe (makilogalamu Pasanathe 300 / m³ youma kachulukidwe) komanso katundu kubala ntchito structural. Choncho n'kofunika kuonetsetsa kuti mpweya entrained mu konkire foamed ali khola nthawi yomweyo ting'onoting'ono kwambiri yunifolomu thovu kuti sizisintha ndi akutali, ndipo musati Choncho kuwonjezera permeability wa phala simenti pakati voids lapansi.

Kukula kwa kupanga-enzyme nthumwi zochokera thobvu, thovu bata utithandize admixtures ndi apadera thovu ikuyambitsa, kuyanjana ndi ikukoka zida bwino mtendere wa thovu ndi choncho thovu konkire, kotheka popanga monga kuwala monga 75 makilogalamu / m³ density.The enzyme tichipeza mapuloteni kwambiri yogwira chiyambi biotechnological ndi sayendera mapuloteni wosakongola hydrolysis.In m'zaka zaposachedwapa foamed konkire lakhala likugwiritsidwa ntchito kwambiri mu misewu, nyumba malonda, nyumba tsoka konzanso, masukulu, nyumba ndi zochitika nyumba m'mayiko monga Germany, USA, Brazil, Singapore, India, Malaysia, Kuwait, Nigeria, Botswana, Mexico, Indonesia, Libya, Saudi Arabia, Algeria, Iraq ndi Egypt.
