Lagu daro la taaban karo oo khafiif ah | Wakiilada Xumbaynta Waxqabadka Sare ee Shabka Gacanta
Warbixin ku saabsan wakiilka xumbo aiyo kala duwanaanshaheeda.
Wakiilka xumbo waa shay kor u qaada samaynta xumbo, oo inta badan u kala baxa laba nooc: surfactant-ka iyo wakiilka xumbaynta. Marka Surfactant-ku soo bandhigo qadar yar, waxay yarayn kartaa xiisadda dusha sare ee dareeraha (yaraynta shaqada loo baahan yahay si loo soo saaro xumbo) ama kordhiyaan xasiloonidooda kolloidal iyaga oo joojinaya isku-dhafka goobooyin. Halka wakiilka xumbaynta uu yahay gaas ka samaysan qaybta gaaska ee xumbo.
Xumbo shub ah waa nooc ka mid ah shubka khafiifka ah ee gaarka ah. Si loo helo godad hawo, waxaad u baahan tahay hab aad hawada ugu dabin karto shubka ka hor inta aysan bilaabin in ay dagto. Dabinnada ugu weyni maaha goobooyin, ama waxaan dhihi karnaa halkan xumbo. Si aad u abuurto xumbo degdeg ah oo joogto ah, waxaan u baahanahay walax xumbo ama kiimiko abuura xumbo ka hor inta aanad ku shubin shubka cad.
Walaxda xumbo-samaynta leh waa nooc ka mid ah walaxda ka dhigi karta in xalkeeda aqueous soo saaro tiro badan oo xumbo ah marka xoogga farsamada hawada la geliyo.. Walaxda noocaan ah waa
wakiilka firfircoon ee dusha(surfactant) ama dusha walax firfircoon. Midka hore waxaa ku jira surfactant anionic, surfactant cationic, surfactant aan ionic ahayn; kan dambe waxa ku jira borotiinka xoolaha, borotiinka dhirta, Saxarkani waa dareere. Wakiilka xumbo shubka leh waxaa sidoo kale loo yaqaan wakiilka xumboynta sibidhka. Wakiilka xumbo la taaban karo waxaa loola jeedaa nooc ka mid ah walxo yareyn kara xiisadda dusha dareeraha ah oo soo saarta tiro badan oo lebis ah iyo xumbo deggan, kaas oo loo isticmaalo in lagu daro shubka xumbo leh.
Cilmi-baaris cusub oo ku saabsan wakiilka xumbo la taaban karo.
By comparing the foam properties of different anionic surfactants with convenient materials and low price, sodium alpha-olefin sulfonate (TO THE) with good foam stability is preferred as foaming component. A new foaming agent for foamed concrete is prepared by adding an appropriate amount of silicone foam stabilizer (zt-1) and thickening material carboxymethyl cellulose (CMC).
(1) By comparing four different anionic surfactants with the same solution concentration, scientists find that the foaming capacity of AOS is the strongest, followed by K12, AES and LAS. In terms of foam stability, AOS is also superior to the other three anionic surface activities and the optimal concentration of AOS solution is 0.80%.
(2) When 0.80%AOS foaming agent mother liquor is mixed with 0.20% organic silicon foam-stabilizing agent zt-1, Xumbadu waxay gaadhay xasilloonida ugu fiicnayd iyo fogaanta dejinta 1-saac waa 4.8mm 38.4 ml.
(3) Iyada oo ku saleysan wax ka beddelka AOS oo leh wakiilka xasilinta xumbo-xajinta silikoonka ee zt-1, xumbada waxaa lagu sii bedelay walxo dhumuc weyn oo carboxymethyl cellulose CMC. Waxaa la ogaaday in marka qiyaasta waa 0.020%, waxqabadka xumbo wuxuu gaaraa heerka ugu fiican, xumbo badan ahaansho 37.5 waqtiyo, masaafada 1-saac ee degitaanka ayaa ah 1.8 mm, iyo dheecaanka 1-saac ee biyaha ah 26.1 ml.
(4) Wakiilka cusub ee xumboynta ayaa lagu dabaqaa diyaarinta 300 ~ 500 cufnaanta hoose ee shubka, iyo alaabtu waxay muujiyeen sifooyin farsamo iyo kulayl oo wanaagsan. 28d xoogga cadaadiska ee fasalka 300 shubka xumbo leh ayaa gaadhay 0.82mpa, ka dibna kuleylku waa 0.062w /(m·K). 28d xoogga cadaadiska ee fasalka 400 shubka xumbo leh wuxuu gaaraa 1.3mpa, ka dibna kuleylku waa 0.075w /(m·K). 28d xoogga cadaadiska ee fasalka 500 shubka xumbo leh ayaa gaadhay 1.9mpa, ka dibna kuleylku waa 0.087w /(m·K).
Waxaas oo dhan ayaa la yiri, Natiijadu waxay muujisay in dusha xumbo ee uu diyaariyey wakiilka cusub ee xumbo-xumada leh uu fiican yahay, dhalaalaya oo deggan. Iyada oo tiro badan oo xumbo ah 37.5 waqtiyo, masaafo dajin oo ah 1.8 mm ku 1 h, barakicin 26.1 ml ku 1 h, dhererka xumbada ayaa weli ka sii badan 50% at 48 h. Wakiilka xumbada ayaa lagu dabaqaa si loo diyaariyo cufnaanta hoose ee shubka.
