Introduction
Bona Foam concrete block machine is the ideal machine for producing foam concrete blocks, which can be used for pouring walls and roofs, and can produce many kinds of foam concrete blocks with different molds, and the blocks can reach the national standard of
JC/T1062, 2007.The blocks produced by this machine have light weight, only 300-1000kg per cube, which can reduce the wall load and building weight, lower the steel ratio, reduce the amount of steel, and reduce the overall cost.
Good fireproof performance, foam concrete block is a completely non-combustible material, high refractory coefficient, low thermal conductivity, can meet the high fireproof requirements.Low water absorption, foam concrete block, the internal is dense independent spherical structure, put into water for 72 hours, still can float on the water, its penetration depth is only 6-8cm, water absorption rate <15%, can meet the requirements of lightweight wall materials.
Excellent heat insulation and sound absorption, soundproof performance, thermal conductivity is only 0.21W/M-K, heat insulation effect is 4 times of clay bricks, can greatly reduce the running time of air conditioning, save electricity consumption. And it has good sound absorption and sound insulation performance, the sound insulation volume of 240mm thick wall is 58dB, which can fully meet the sound insulation requirement of common wall and subdivision.The blocks produced by this machine reduce the self-weight of the building and improve the seismic capacity due to its light weight, and the blocks have a flat appearance, which reduces the amount of mortar used for wall building and painting, thus greatly reducing the construction cost and realizing the economic and social benefits of this product. Reduce pollution, protect the environment and create a low-carbon environment, thus will strongly promote the process of wall reform in China.
Working principle
The machine is an ideal machine for producing light weight concrete blocks with cement foam. Its production process is to prepare foam diluent from foam aqueous solution by physical method and inject it into the slurry made of cement, river sand light weight aggregate
and water by high pressure foaming, then mixed and mixed, poured into shape, natural maintenance, formed and cut into light weight porous concrete blocks, also known as foamed concrete blocks, which is a new type of environmental protection wall material, and the specifications of the blocks can be adjusted arbitrarily to meet the needs of various walls.
Equipment commissioning
1、Adjust the operation direction of air compressor, adjust the pressure switch and safety valve according to the safety regulations, adjust the tightness of v-belt, check the oil level of compressor, if lacking, please fill to the red circle range in the middle of the
oil mirror, the lubricant should be selected compressor lubricant L-DAB100, GB12691 (i.e. equivalent to the old international summer HS - 19, winter HS - 13).
2、Adjust the running direction of the host mixing barrel motor, check the oil surface height of the reducer lubricating oil, and add appropriate lubricating oil, and fill the transmission chain with lubricating grease regularly to prolong the service life.
3、Adjust the running direction of the pump, and set the water supply time of the pump according to the machine specifications and production needs, and do not adjust it arbitrarily after setting, so as not to affect the quality of the products.
4、First place the moulds used in accordance with the regulations, the ground should be coated with isolating agent or pavement film, and the moulds should be coated with machine oil around in order to release the moulds.
5、Check whether the main machine's water and gas pipelines are smooth, and whether there is water and gas leakage, and unclog and seal them.
Raw material
The cement and admixtures used in the production of foam concrete blocks should conform to the following regulations.
1、Cement should conform to the provisions of GB175 and TCP33.
2、Sand should comply with the provisions of GB/T14684
3, fly ash should comply with the provisions of GB/T1596.
4, finely ground slag powder in line with the provisions of GB/T18046.
5, the use of other active mineral powders for blending should be in line with the requirements of the relevant national standards and norms.
6, when mixed with industrial slag, the level of radioactivity of the slag should be in line with the provisions of GB6566.
7, admixtures should be in line with the provisions of GB8076.
8, foam agent, the foam prepared by physical methods into an aqueous solution of foam agent should have good stability, and uniform size of the pore aperture.
9, water should be in line with the provisions of JGJ63.
