  • There is an experimental study of monolithic foam concrete "SOVBI" samples with a density of 205 kg /m3 (grade D200) for combustibility. The evaluation criteria are the following values of combustion characteristics: temperature increment in the furnace, duration of the stable flame burning, and sample mass loss. The experimental results show the following values for foam concrete: temperature increment in the furnace of 2 °C, duration of the stable flame burning of 0 s, and sample mass of 24.4% The foaming principle of protein foaming agent is the degradation of the protein. The cleavage of peptide bonds in protein macromolecules will produce soluble protein-small molecules. With the increase of protein-small molecules in the solution, hydrophobic groups gradually increase, which reduces the surface tension and forms an interface.In addition, due to the formation of hydrogen bonds between special groups in the molecule, strong hydrogen bonds can ensure the formation of high-strength fo The performance of animal protein foaming agents is similar to that of plant protein foaming agents, and its foaming capacity and stability are identical to that of plant protein. However, its raw material resources are not as extensive as plant protein, so the full production scale and application amount are not as comprehensive as plant protein. No matter what animal protein foaming agent, the general shortcomings are high price (1.6 ~ 18,000 yuan/ton), the foaming ratio is lower than syntheti The protein-type foaming agent is a high-grade foaming agent with good performance and good development prospects. From the general development trend, it will occupy an increasing proportion of applications in recent years. Although its price is very high (mostly above 15,000 yuan/ton), the market will still accept it due to its good performance. The protein foaming agent is a surface-active substance. Their common outstanding advantage is that the foam is remarkably stable, can last a long time There are mainly three indicators: foamability, foam toughness, and bleeding, to measure the quality of foaming agents.
