Planting grass brick manufacturers take you to understand the entire process of planting grass bricks
How does the grass plant equipment produce grass plant?
1. Raw material processing. First, crush the good raw materials, and then choose equipment according to some factors such as the moisture content of the coal gangue, hardness, product, particle requirements, and dust removal. In addition to the normal stirring process of raw material processing, in the aspect of deep processing, an additional rolling process is needed to increase the strength of the product. Establish sufficient aging library to ensure that the aging time of raw materials improves the plasticity index.
2. Extrusion molding. Select a vacuum extruder, using hard plastic molding, the molding pressure is greater than 2.0MPA, the vacuum degree is greater than -0.09MPA. Considering the product upgrade, there is a certain power space and room for product expansion when purchasing equipment.
3. Dry roast. It adopts domestic advanced fast drying and one-time firing of tunnel kiln, realizes mechanization in operation process, and realizes automation in temperature control, achieving high production efficiency, less labor capacity, and easy management. How to improve the compressive strength of sintered brick manufacturers
Prolong the holding time under appropriate conditions: It has been proved through tests that the same raw materials, brick machines, the same heating and cooling rates, and the sintering temperature are 800 ° C, because if the holding time is different, the compressive strength of the sintered brick is also It's different, so appropriately extending the holding time is beneficial to improving the compressive strength and quality of the sintered brick.
Properly increase the temperature of the sintered bricks: Tests show that the same raw materials and the bricks produced by the brick machine have different firing temperatures and different strengths of the sintered bricks. The test results show that the compressive strength of the brick increases with the increase of the firing temperature of the tunnel kiln. The research on new-type grass planting bricks has far-reaching significance. The technology is constantly developing and the times are constantly improving. If we do not move forward, we will lag behind people. Environmental protection is an enduring topic for human beings. The same is true of the brick industry. It is common for manufacturers to fire qualified planting grass bricks, that is, ordinary manufacturers, to produce excellent planting grass bricks, and even to develop more advanced bricks.
Autoclaved aerated concrete is made of cement, lime, slag, sand, fly ash, aluminum powder, etc. as the main raw materials. It is made by grinding, metering, mixing, pouring, gas expansion, static cutting, and autoclave curing. Lightweight concrete.
China began to conduct research on aerated concrete in 1958. Industrial tests and applications were carried out in 1963. In 1965, a full set of technical equipment was introduced from Sweden's Sipolex Company. The aerated concrete plant in Beijing was completed in 1966 with an annual production capacity of 130,000 m3. Subsequently, several key technologies and equipment were introduced from Poland, Romania, and Germany, and production lines were established in Harbin, Nanjing, Shanghai, and Hangzhou. In the early 1970s, China began to digest and absorb imported technology and equipment, and built a production line with an annual output of 100,000 m3 in Beijing Silicate Products Factory. Since then, through continuous research and development, a number of specialized technologies, equipment, supporting materials and manufacturers have been established, professional research and design and technologies with intellectual property rights have been formed, and an independent industry system has been established.
The development of aerated concrete in Guangdong began in 1993. The first aerated concrete production company in Guangdong Province was jointly invested by Huaye Resources Construction Company and Shajiao Power Plant to build Dongguan Humen Ferris Building Material Industry Company with an annual production capacity of 400,000. m3. The put into operation of Ferris Building Materials Company has filled the gap of aerated concrete production in South China, and promoted the rapid development of the aerated concrete industry in the entire Pearl River Delta. At present, there are nearly 60 aerated concrete manufacturers in the Pearl River Delta region, with an annual production capacity of about 5 million m3.
For the research of new grass planting bricks, Guangzhou Wanxin Cement Products has been working hard. Through this aspect, we can improve our industry awareness and brand awareness.
