2, performance characteristics
(1) The system has no solvent construction, is environmentally friendly and tasteless, and the TVOC content is low, which can pass the new national standard.
(2) The micropores can be adjusted and elastic, effectively increase the motion buffer, reduce the ankle, joint and ligament injury, and easily pass the new national standard shock absorption vertical deformation index.
(3) wear-resistant anti-slip, acid and alkali resistance, mildew proof, waterproof, strong stain resistance, bright and beautiful appearance, simple construction and maintenance.
3. Scope of application
(1) various sports venues such as stadiums, tennis courts, basketball courts, volleyball courts, etc.; (2) children's paradise, kindergarten activity venues;
(2) Pedestrian walks, communities, playgrounds and other entertainment venues.
4, recommended operating temperature
The construction temperature of
Polyurethane Paving Materials is controlled at 5-35 °C.
5, storage and packaging
Specifications: 250kg / barrel.
Store in a cool, dry place away from direct sunlight and store at temperatures below 30 °C. The warranty is 6 months. After the warranty period, it can still be used normally after passing the test. Please pay attention to the seal to save.
Construction process:
1. Pure PU course: On the basis of the treated cement foundation or asphalt, the AB material and the catalyst are uniformly mixed according to the ratio and then paved.
2. Mixed stadium and mixed runway: On the basis of the treated cement foundation or asphalt, the AB material, black particles and catalyst are uniformly mixed according to the ratio and then paved.
3. The theoretical dosage of this product is 1.25kg/m2/mm (the amount varies depending on the basic material), and the construction is evenly omitted.
4, after the surface can be on the person (about 24 hours, the surface does not stick to the hand, depending on temperature, humidity, etc.), and then proceed to the next construction.
Precautions:
1. Construction should be avoided in rainy or wet weather to avoid affecting interlayer adhesion.
2. After the material is properly prepared, it should be used as soon as possible. The remaining material can not be returned to the original packaging. The material after opening should be sealed and stored.
3. All the utensils should be cleaned with the matching thinner in time and dried for use.
safety warning:
This product should be stored, transported and constructed in accordance with the regulations. Pay attention to eliminate fire and keep away from heat. The ventilation is perfect, cool and dry, and strengthen labor protection.
