Foam cement has the following technical advantages: a product density reduce the minimum up to 280kg / m3, dry wood density than conventional even lower 50%; 2 effectively improve the heat insulation performance cement products; 3, especially combined with our development and production of the GX-7 # foam modifier can be cured after the product voids and pores in the wall to form a layer of water-repellent film, effectively prevent water vapor permeability. Foam concrete: There are two general, one is generally added to the foam cement, and water by mechanical agitation forming a porous conservation made, lightweight insulation material called foam concrete; another with powder ash (or other industrial waste) adding the right amount of lime and plaster and foam, by mechanical mixing, forming, curing made of a porous, lightweight insulation material called fly ash foam concrete. Asphalt perlite: based asphalt cements, with perlite aggregate, with a certain mix, mixing, screening, molding, curing together. It has a small capacity, low thermal conductivity, high bearing capacity, construction convenient, economical and durable. Vermiculite cement stones: is vermiculite aggregate, cement for cementitious materials, according to a certain percentage of the preparation. Vermiculite: is a mineral, monoclinic crystal form similar to mica, flaky, with a greenish-brown or golden yellow fat luster. Hardness of 1 to 15, the proportion of 2.4 to 2.7, produced in the veins containing gold mica or biotite alteration of, is biotite and phlogopite changing product, after roasting is called "vermiculite", volume can be expanded from 18 to 25 times, significantly reduced the proportion used as insulation material (direct use of granular vermiculite or made of cement and asphalt vermiculite vermiculite) and lightweight aggregate concrete and mortar. Cement Perlite: Perlite is to aggregate, cement for cementitious materials, according to a certain percentage of the preparation can be used for wall plastering, roofing or folder can be used for wall insulation layer, etc. cast. The main features of foam concrete foam plus large, the amount of foam is generally 1 to 6 times the Pastes for. In most cases, the foam volume greater than the volume of cementitious material, i.e., how much foam slurry. When producing a density of 200 to 300 kg / m3 foam concrete, foam volume of 70% to 80% by volume of the total, the proportion of cementitious slurry of only 10% to 20%. . On the other hand Pastes density, heavy, and foam density is very small, very light, a huge difference in density between the two mixed difficulty is exacerbated. A further aspect, the foam is very easy to burst, the higher the longer the stirring time burst rate, a stirrer structure if no specificity, the loss rate of the foam can reach 30% to 70%. These three characteristics, so the difficulty of foam concrete mix is ??very large, the use of ordinary concrete mixer mortar mixer or foam into the mix and it is difficult to mix, mixing time is short do not go in the bubble mix, stir and long time foam loss rate is very high . Therefore, foam concrete mix must be using a dedicated mixer. This machine is designed for the characteristics of foam concrete, it can quickly foam mixing, mixing time only tens of seconds, the foam loss rate of less than 5%, with the function of the protective bubble, and when the bubble content of the slurry reaches 3 ~ 6 times also make gel slurry and foam mixed thoroughly to form a sponge-like foam slurry. Mix at low speed due to the foam does not enter, but at a high speed and easy to burst, so the foam concrete mixer speed is generally 60 rev / min.
