1. Inzululwazi yezinto eziphathekayo kunye neeNdlela zokuSebenza
1.1 Intsingiselo kunye noHlelo lweeMixube eziKhala
(I-Lightweight Concrete Admixtures)
Imixube yekhonkrithi ekhaphukhaphu ziikhemikhali ezikhethekileyo okanye izongezo zomzimba ezenzelwe ukunciphisa ingxinano yeenkqubo zesamente ngelixa ugcina okanye uphucula ubume kunye nokusebenza kakuhle..
Ngokungafaniyo neeaggregates zemveli, le mixube inika i-porosity elawulwayo okanye ibandakanya izigaba zoxinaniso olusezantsi kwimatrix yekhonkrithi., okukhokelela kubunzima besixhobo esisuka kwi 800 ukuya 1800 kg/m ZIMBINI, xa kuthelekiswa nama-2300– 2500 kg/m ³ ukwenzela ikhonkrithi eqhelekileyo.
Zahlulwe ngokubanzi ngokweendidi ezimbini: ii-agent ezikhupha amagwebu ekhemikhali kunye ne-preformed light-weight incorporation.
Abameli bekhemikhali bekhemikhali benza kakuhle, izithuba zomoya ezizinzileyo ngokusungulwa kwerhasi ekwi-situ– ngokuqhelekileyo ngokusebenzisa umgubo we-aluminiyam kwi-autoclaved aerated concrete (I-AAC) okanye i-hydrogen peroxide ene-catalysts– ngelixa ukufakwa kwangaphambili kubandakanya i-polystyrene eyandisiweyo (EPS) iinkozo, iperlite, i-vermiculite, kunye ne-ceramic engenanto okanye i-polymer microspheres.
Izahluko ezikwinqanaba eliphezulu zikwabandakanya i-silica enanostructured permeable, ii-aerogels, kunye nokuqokelelwa kwakhona kobunzima bokukhanya obuvela kwimveliso yemveliso efana neglasi eyandisiweyo okanye i-slag.
Ukukhethwa kwe-admixture kuxhomekeke kwi-thermal insulation efunekayo, amandla, ukumelana nomlilo, kunye nokusebenza, izenza zisebenziseke kwiimfuno ezahlukeneyo zokwakha.
1.2 Ulwakhiwo lwePore kunye noBudlelwane boXinano lwePropathi
Ukusebenza kwekhonkrithi enobunzima obulula kulawulwa yi-morphology, ukuhanjiswa kobungakanani, kunye ne-interconnectivity ye-pores evezwe yi-admixture.
Iinkqubo ezifanelekileyo ziquka ukusasazeka ngokulinganayo, imingxuma yeseli evaliweyo kunye nobukhulu phakathi 50 kwaye 500 iimicrometers, okunciphisa ukufunxwa kwamanzi kunye ne-thermal conductivity ngelixa uthatha inzuzo epheleleyo yokusebenza kwe-insulation.
Vula okanye iipores ezidibeneyo, ngelixa kuncipha ukuxinana, inokubeka esichengeni amandla kunye nokuqina ngokunceda ngokufikelela kubumanzi kunye nomonakalo owenziwe ngumkhenkce.
Imixube ezinzisa kakuhle, amaqamza ahlukeneyo– njengeprotheyini-esekelwe okanye i-artificial surfactants kwikhonkrithi yogwebu– nyusa uzinzo lomatshini kunye nokusebenza kakuhle kwe-thermal.
Ubudlelwane obuguqukileyo phakathi koxinaniso kunye nokuqina koxinzelelo lusekwe kakuhle; nangona kunjalo, Imixube yale mihla inciphisa urhwebo ngoxinaniso lwematrix, ukuqinisa ifayibha, kunye neerejimeni zokunyanga eziphuculweyo.

Umzekelo, Ukudibanisa umsi wesilica okanye uthuthu lwempukane kunye nabameli abaqhuma igwebu, lungisa isakhelo sepore kwaye yandisa intlama yekhonkrithi., ukwenza ikhonkrithi enobunzima obuphezulu obuphezulu (ixhomekeke ku 40 MPa) kwizicelo zoyilo.
2. Uhlobo oluPhambili lwe-Admixture kunye neendima zabo zobuNjineli
2.1 Ii-Brokers eziFoaming kunye nezisombululo zokungenisa umoya
Iiprotheyini ezisekelwe kwiprotheyini kunye nabameli be-synthetic frothing zisisiseko sokuveliswa kwekhonkrithi ye-foam, ukudala amaqamza omoya akhuselekileyo adityaniswe ngoomatshini kwi-concrete slurry.
Amagwebu eprotheyini esempilweni, evela kwizilwanyana okanye kwimithombo yemifuno, zibonelela ngokhuseleko lwamagwebu aphezulu kwaye zilungele izicelo ezinoxinano oluphantsi (
I-Cabr-Concrete ngumthengisi we-Concrete Admixture ene-over 12 iminyaka yamava kwi-nano-building energy yogcino kunye nophuhliso lwe-nanotechnology. Iyayamkela intlawulo ngekhadi letyala, T/T, I-West Union kunye ne-Paypal. I-TRUNNO iya kuthumela iimpahla kubathengi phesheya ngokusebenzisa i-FedEx, DHL, ngomoya, okanye ngolwandle.
