Kupaka pulasitala wopepuka wopaka omanga

Sinthani chinyezi cha mpweya

Chinyezi chakunja chikakhala chambiri kuposa chinyezi cha pulasitala gypsum, chifukwa kuthamanga kwa nthunzi yakunja kumakhala kwakukulu kuposa kukhathamira kwake kwa nthunzi, machitidwe amkati amayambitsidwa ndi chinyezi, potero amachepetsa kuwonjezeka kwa chinyezi; chinyezi chakunja chikakhala chotsika kuposa chinyezi chofananira ndi gypsum, Kutulutsa kwa nthunzi yakunja kumakhala kotsika poyerekeza ndi kukhathamira kwake kwamatope, komwe kumalimbikitsa kutuluka kwamamolekyulu amadzi amkati, chifukwa chake kumatha kutengapo gawo pakuwongolera ndi kuwongolera chinyezi.

Katundu womanga amachepetsedwa bwino

Kuchuluka kwake kwa pulasitala ndi 750-950kg / m³; theka lokha la matope opaka simenti 1800-2000kg / m³. Mwachitsanzo, ngati nyumba (mayunitsi awiri okhala ndi pansi 20) imalowedwa m'malo ndi kuyika pulasitala m'malo mwa matope achikhalidwe a simenti, nyumba yonse Ichepetsa katunduyo ndi matani 550.

Lawi wamtundu uliwonse

Kulemera kwake kwa pulasitala wopepuka ndi 172, ndipo kulemera kwake kwamadzi ndi zaka 18. Nyumba yanyumba zazikulu 100 ikakumana ndi moto, kutentha kufika 110°C kapena kupitilira apo, dihydrate gypsum imamasula mwachangu madzi a kristalo ndikusandulika hemihydrate gypsum kenako ndikusandulika gypsum yosazizira. Hydrogypsum imatha kumasula 560kg yamadzi. Madzi amatha kutentha kwambiri panthawi yamvula, yomwe imatha kuletsa kutentha kwanyumba ndikuthandizira kuthawa.

Kuyamwa kwamphamvu ndi kukana kwamphamvu

Pakukhazikitsa pulasitala, pamakhala ma void ochepa mkati, chifukwa imatha kuchepetsa kuthamanga kwa mawu, kulepheretsa kuyerekezera kwamphamvu, imatha kusintha mphamvu yamphamvu kukhala mphamvu yotentha, motero imakhala ndi magwiridwe antchito abwino. Chifukwa chakapangidwe kake kopindika, imatha kuyamwa mphamvu, motero siyingagwedezeke ikangowonongeka.

Kutchinjiriza

Kutentha kwamatenthedwe kupaka pulasitala ndi 0.17W / MK, ndipo matenthedwe otenthetsa matope amtundu wa simenti ndi 0.93W / MK, chifukwa chake kutentha kwa pulasitala ndi 20% ya matope a simenti, omwe amakhala ndi matenthedwe ena kutchinjiriza zotsatira. , Ikhoza kuchepetsa kugwiritsidwa ntchito mphamvu kwa nyumbayi.

Kugwira ntchito molimbika kwa ogwira ntchito

Popeza kuchulukitsa kwa pulasitala kumangokhala pafupifupi theka la kuchuluka kwa matope a simenti, ogwira ntchito amangofunika kulipira theka la mphamvu zathupi lomwelo ​​zomangamanga, kotero kuti mphamvu ya ogwira ntchito idzachepetsedwa, ndipo ntchito yomanga idzathandizanso. Kuphatikiza apo, palibe kuchiritsa kofunikira pambuyo popaka pulasitala ndi kupaka pulasitala, ndipo nthawi yolowera hydration ndiyochepa, ndipo njira yotsatira ikhoza kumangidwa pambuyo pa maola 24.

Eco Wokonda

Gypsum itachitika mosavomerezeka, ilibe zosungunulira zosungunuka. Zida zopangira simenti ndi zowonjezera zomwe zimagwiritsidwa ntchito ndizogulitsa zachilengedwe. Kupaka pulasitala gypsum kopepuka sikumatulutsa zinthu zovulaza monga formaldehyde, yomwe ndi yosamalira zachilengedwe komanso yotetezeka.
