Kevyet betonin lisäaineet | Tehokkaat vaahdotusaineet solubetonille
Cement foaming agent is the core material in foamed concrete. Only a good cement foaming agent can make high-performance foamed concrete products. Five kinds of cement foaming agents are introduced. They are magnesium oxychloride cement foaming agent and pine foam. Soap type cement foaming agent, munankeltuainen betonisementtivaahdotusaine, concrete compound foaming agent, cement foaming agent for engineering.
1. Hartsi saippua sementti vaahdotusaine: start mixing rosin and caustic soda, mixing and heating; liuotetaan sitten SM superpehmitin, sitruunahappoa ja piijauhetta vedessä, and put the above two mixtures into the water by heating and maintaining Mix in the heating container, lisää vesi ja sekoita tasaiseksi, add the required amount of rubber powder to the above-mentioned secondary mixture and mix. Verrattuna olemassa oleviin taitoihin, the choice of composite foaming method has greatly improved the quality of the commercial foam. The inner wall of the foam formed by the foam can also form a very thin polymer crystalline film with waterproof function. Participate in the cement foaming agent The mortar also has better insulation function.
2. Concrete composite foaming agent: including the following processes
(1) Valmista sopiva vedeneristysaine; (2) Make quantitative foaming agent; (3) Make some syntactic foaming agent; (4) Write the foamed foam into the foamed concrete mixture, mix it, and then cast it into shape. After the foamed concrete is added with the waterproof concrete composite foam agent prepared by the above method, it can overcome the shortcomings of its large water absorption rate, so that the waterproof thermal insulation and thermal insulation functions are significantly improved.
3. Egg yolk concrete cement foaming agent: Choose the following method to make: first mix cement, keraaminen jauhe, vettä, jne. tietyn massasuhteen mukaan, sekoita tasaiseksi ja valmista sementtibetoniliete. Then mix the egg yolk, stabilointiaine, dispergoiva aine, säilöntäaine, and water in a certain mass ratio to form a uniform and fine closed-cell foam. Take a certain volume of the foam to the side of the cement concrete slurry, sekoita tasaiseksi, and pour it into a mold for maintenance. The cement foaming agent has easily available materials and simple foaming technology, which overcomes the shortcomings of poor stability of traditional surfactants, lack of materials and high cost of animal and plant protein cement foaming agents.
4. Magnesiumoksikloridisementtivaahdotusaine: first mix and mix appropriate bone glue and urea-formaldehyde resin with 10 times the amount of water, heat and smelt for about half an hour after the temperature reaches 75 degrees to form a glue solution, and then add dodecyl benzene sulfonate Sodium, trietanoliamiini, jne. ovat sekoittuneet, heated for about 5-10 minutes after the temperature reaches 75 astetta, and finally diluted with water to make a commercial product. Ominaisuudet: Good quality of goods, alhaiset kustannukset, ja menetelmä on hyvin yksinkertainen.
5. Sementtivaahdotusaine suunnitteluun: the common ones are linear alkyl sulfate, foam stabilizer alkyl alcohol amide and fatty alcohol polyoxyethylene ether sodium sulfate, ylimääräinen kalsiumkloridi, jne. Valmistustekniikka on seuraava: the ingredients are mixed and mixed uniformly under normal temperature.
