Epoxy self-leveling is a kind of ground construction technology. The coating used is made of epoxy resin and special curing agent as the main material. It is processed by adding various additives, pigments and fillers through strict proportioning. This construction technology can flow according to the irregularity of the ground, leveling the ground automatically and drying quickly. It not only has excellent chemical properties such as water resistance, oil pollution resistance and chemical corrosion resistance, but also has good adhesion, high mechanical strength, low shrinkage rate of cured paint film, and can be coated into thick film at one time. It has excellent practical performance and wide application range.
Scope of application
Epoxy self-leveling floor is suitable for dust-free or sterile rooms in pharmaceutical industry, blood products industry, medical industry, biological research, electronics and microelectronics industry which implement GMP standard.
It is also applicable to other industries requiring beauty, wear resistance, impact resistance and chemical protection, such as schools, offices, chemical plants, food factories, etc.
The construction technology of epoxy self-leveling floor is divided into base treatment, painting closed primer, scraping middle coat, and finally self-leveling epoxy topcoat upsetting.
Grass-roots treatment should ensure the strength of the ground, clean surface, no loose animal material, no empty drum. The ground evenness should be checked with 2 m ruler and wedge plug ruler. The allowable deviation is not more than 4 mm, and the water content should be less than 6%.
Brushing sealing primer requires no leakage, so that the primer penetrates into the cement base. The maintenance time of primer is 12 hours. After confirming the hardening state, the next painting process is carried out.
Scraping mid-coat paint should be uniform and smooth, and should not be missed. The last step is topcoat, because the effective time of material use is about 30 minutes, the application should be as fast as possible, the requirement is not to leak out, the surface is smooth, flat, without obvious defects.
The epoxy self-leveling floor should be maintained for 7-10 days before it can be put into use. Water or other solution should be avoided to infiltrate the surface during the maintenance period. Daily cleaning after that should be done with a soft mop with good water absorption or a dry-wet dual-purpose vacuum cleaner.
Secondly, every employee who enters the workshop must change into rubber-soled shoes, so as not to bring the outside sediment into the workshop and scratch the ground.
Hard objects and machinery should be wrapped up with soft plastic when they are used, and cardboard boxes should be laid on the floor to avoid scratching the ground in the course of transportation equipment.
The acceptance standard of epoxy self-leveling flooring is mainly to observe the surface. When the ambient temperature is 25 C, the hardness of the flooring should reach about 80% of the solidification after 2-3 days of construction.
At this time, the surface can not appear sticky, foaming phenomenon. Surface should be smooth and smooth, no floating color, uniform color, large area of interface allowed to have very little obvious color difference.
1 mm epoxy self-leveling floor: 25-32 yuan/level;
2mm epoxy self-leveling floor: 30-45 yuan/level;
3mm epoxy self-leveling floor: 45-65 yuan/level.
