Production of fluorine gypsum blocks

The characteristics of the process is, in the gas in the production of gypsum aerated block, and a half to gypsum and lime slurry introduced in aluminium as gas agent, the gypsum aerated block of gas and condensate gas and hardening process is completed at room temperature. The results show that the gas gypsum aerated block production process is simple, low cost, excellent product performance, economic benefit is remarkable.The xin-ya Yang to gas gypsum as raw material to produce gypsum block. From CaO, slag, cement, sulfate, alum stone, extract the two kinds of inorganic substances such as chlorine salt compound excitation agent and JF2 in order to improve the hydration rate. Production of gypsum block material proportioning is: gas gypsum 45% ~ 50%, beta half water gypsum 25% ~ 40%, 0 ~ 20% of fly ash, lime 3% ~ 5%, 0.2% ~ 0.5%, spreads JF2 0.2% ~ 0.5%.Chlorine production process is: anhydrous gypsum and fly ash in 40 mesh, add lime, beta half water gypsum, admixtures, such as mixing, the thick determination method for determining the construction plaster, standard consistency water pouring shape, after natural curing to release its strength were tested. Produced by the method of the gypsum block 28 d compressive strength of 13.8 MPa, far more than that stipulated in the international standards ISO/DP7549 density is 800 ~ 1200 kg/m3 block the standard of the compressive strength is greater than 5 MPa.Gas gypsum aerated block has a small volume density, low thermal conductivity, heat preservation, heat insulation, sound insulation, fire prevention, enough mechanical strength, etc. After application in building, can reduce the investment structure, speed up the construction progress, greatly improve the effect of building energy saving, effectively adjust the indoor temperature. Gypsum aerated block at the same time, the use of gas, still can save wall materials transportation costs by more than 30%, has the benefit of construction unit and the use of units. Therefore, the development and utilization of the product is not only beneficial to environmental protection and make full use of resources, and for manufacturers and users and the construction unit has good economic benefit
