  • Influence of upstream and downstream industries on aerated concrete equipment
    To understand the impact of the aerated concrete equipment industry from upstream and downstream, firstly we need to understand what are the upstream industries of the industry, and what are the downstream industries of the industry, from the analysis of the upstream and downstream industries to understand the prospects for the development of the industry.
      The downstream industry of aerated concrete equipment industry mainly refers to projects that can make use of aerated concrete, which accounts for the largest proportion is the real estate project, since the reform and opening up, we will find more high-rise buildings here. In the construction of high-rise buildings, building materials with light weight and thermal insulation are needed, and aerated concrete with a thickness of 4cm can achieve the thermal insulation effect of 240cm clay bricks, with obvious thermal insulation performance, while the bulk weight is generally 400kg/m3-700kg/m3, which is equivalent to 1/3 of hollow clay bricks, 1/5 of solid clay bricks, 1/4 of concrete, and lower than the general light aggregate concrete. It is also lower than the weight of general light-aggregate concrete, and it is easy to construct and can help builders save construction cost, so naturally it is widely used in real estate projects. Nowadays, most of the floors are frame structures, and aerated concrete is also an ideal material for renovation of houses. Its upstream industries are mainly the steel industry, parts suppliers and other basic industries. The upstream industry, especially the steel industry, has a large impact on it. The amount of steel used in a set of equipment is huge, and the price of steel directly affects the manufacturing cost to a certain extent.
      The upstream industry directly affects the manufacturing cost of aerated concrete equipment industry, especially in the past two years, the steel market fluctuations are more violent, which has caused a certain impact on the development of the industry, but the biggest impact is still the downstream real estate industry. The real estate industry directly affects the investment in the construction of aerated concrete plants, if the market demand slows down, the project investment fever will also be reduced, which will naturally affect the development of the manufacturing industry. The understanding of the upstream industry will be beneficial to the development of manufacturing enterprises.
  • The strength of aerated brick produced by aerated concrete block equipment is affected by the raw materials of aerated brick
    1. Cement. The main inspection indexes of cement are as follows: stability, fineness, standard consistency, water consumption, setting time, flexural strength and compressive strength. The strength of aerated brick depends on its components: the comprehensive effect of hardened cement paste, interface transition zone and aggregate strength, and the cement strength is closely related to the strength of aerated brick equipment block, The factors affecting the cement strength also affect the strength of aerated brick blocks.
    2. Fine aggregate. Fine aggregate has a great impact on the strength of aerated brick mainly due to the fineness modulus and mud content. The finer the sand is, the more unfavorable it is to the strength of aerated brick. The increase of mud content not only affects the strength of aerated brick, but also adversely affects the frost resistance and other characteristics of aerated brick.
    3. Coarse aggregate. The main factors affecting the strength of aerated brick equipment block by coarse aggregate include orthopedic strength, mineral composition, large particle size and so on. Because the strength of aggregate is much higher than that of cement slurry matrix and interface transition zone, the strength of aggregate has not been fully utilized. Only when the strength of cement slurry matrix and transition zone is higher than or close to the strength of aggregate, it is necessary to seriously consider the strength of aggregate. Secondly, the different composition of aggregate minerals will also affect the strength of aerated brick blocks. The increase of the needle and flake content of the aggregate will have a great adverse impact on the aerated brick block, because the needle and flake orthopedics has large surface area and large internal friction. When the content increases, it will increase the surface area and porosity of the coarse aggregate, reduce the fluidity of the aerated brick mixture, and aggravate the phenomenon of dew stone and segregation. Needle flake particles will not only affect the workability, cement dosage and strength of aerated brick block, but also affect its durability. How to place the embryo in the mold of aerated concrete production line will deteriorate the performance of aerated brick block, increase the porosity of aggregate and increase the unit water consumption and deformation.
    The price of non fired brick machine is not important. The price of non fired brick machine is not the standard for selecting equipment. As customers who buy brick machine equipment now, they always put the purchase standard on the price when buying hydraulic brick machine. If the price is cheap, they have a strong desire to buy. If the price is high, they will directly dispel their desire, I don't consider the quality and performance of the equipment at all. I'm only interested in the price of the equipment. As a manufacturer, I'm also very confused. It's incorrect to think so. In terms of considering the price of brick machines without considering other aspects, this view should be improved. As customers, they should pay more attention to the overall performance of the equipment, whether they can produce normally and whether they can keep up with the output demand. As every manufacturer, they will encounter the problem of bargaining when customers buy equipment, This problem is very common in the market. There is no standard for the sales of brick machinery equipment in the market, and the equipment price fluctuates. The user can communicate with the seller, try to talk about the price that can be agreed by both sides, and ensure that the manufacturer has income, so that the agreement can be reached between the two sides. Especially with the rapid development of brick machinery and equipment, the scope of use of non fired brick is becoming larger and larger. It can be said that its application has been extended to every corner of people's life from now on, The appearance of colored bricks has changed people's life. The pavement is not only bright in color, but also can quickly absorb the ponding on the pavement. No matter how large or heavy vehicles roll, they will not deform the highway. According to the relevant departments, this kind of polymer permeable pavement that can also reduce noise will become a wide range of bricks to be promoted nationwide in the future. This new type of brick will also break the original black-and-white pattern of traditional black-and-white roads. With new changes, it can also brighten people's eyes, have a refreshing feeling, and instantly make people feel happy.
