The standard of anti-slip bricks in schools and their technological processes.
First, the standard of anti-slip bricks in schools
School anti-slip brick refers to the anti-slip and wear-resistant tile specially used for laying on the ground of the school, and its standards mainly include the following aspects:
1.Anti-slip performance: The first criterion for anti-slip bricks in schools is anti-slip performance. The surface of the non-slip brick should have a certain roughness to increase the friction between the sole and the ground, so as to effectively prevent students from slipping while walking or running. The anti-slip grade of anti-slip bricks should meet the standards set by the state or industry to ensure the safety of students on campus.
2.Abrasion resistance: School anti-skid bricks also need to have good wear resistance. School floors are often rubbed by students walking, running, exercising, etc., so non-slip bricks should have a certain degree of wear resistance, which can withstand long-term use without being easy to wear. The quality of wear resistance is directly related to the service life of anti-slip bricks.
3.Anti-pollution performance: School anti-slip bricks should also have good anti-pollution performance. School floors are susceptible to the erosion of pollutants such as dust and stains, so non-slip bricks should have the characteristics of not easy to absorb pollutants and easy to clean to keep the ground clean and beautiful.
4.Environmental performance: The environmental performance of school anti-slip bricks is also a factor to consider. The use of toxic and harmful substances should be avoided in the production process of anti-slip bricks, and the environmental protection standards of the country or industry should be met. At the same time, the radioactivity indicators of non-slip bricks should also comply with relevant regulations to ensure the health and safety of students.
Second, the process flow of school anti-slip bricks
The production process of school anti-slip bricks mainly includes the following steps:
1.Raw material preparation: According to the formula requirements of non-slip bricks, prepare the required raw materials, such as clay, quartz sand, feldspar powder, etc. Ensure that the quality of raw materials meets the production requirements to ensure the quality of anti-slip bricks.
2.Batching and mixing: The prepared raw materials are batched according to a certain proportion, and fully stirred through the mixing equipment. The accuracy of the ingredients directly affects the performance and quality of the non-slip bricks.
3.Moulding: The stirred mud is pressed into the shape of non-slip bricks through the molding equipment. During the molding process, it is necessary to control the parameters such as water content, pressure and molding time of the mud to ensure the dimensional accuracy and appearance quality of the anti-slip bricks.
4.Firing: Put the formed non-slip bricks into the kiln for firing. During the firing process, it is necessary to control the temperature, time and atmosphere and other factors to ensure the sintering degree and performance of the anti-slip bricks.
5.Cooling & Grading: After firing, the non-slip bricks are naturally cooled or forced cooled, and then graded and screened according to the specified size and performance standards.
6.Inspection and packaging: quality inspection of anti-slip bricks after grading and screening, including tests of anti-slip performance, wear resistance, anti-pollution performance, etc. Qualified products are packaged and marked with corresponding identification and specification information.
Through the strict control and management of the above technological processes, high-quality products that meet the standards of anti-skid bricks of the school can be produced, providing a safe, comfortable and beautiful campus environment for the school.
