Mixed runway construction plan
First, the ratio
The bottom layer is mainly composed of QD-02 or QD-A: QD-B=4:1
Middle layer: 3071A/3071B black particles
Finish: Two-component topsheet 303A/3031B
Second, the process
1. Basic ground treatment, including removal of debris, ground grinding, treatment of expansion joints, and equality.
2. According to the dosage of 0.15kg/m2, evenly spray or spray the primer evenly on the ground in the case of drying the cement floor to achieve the state of no film formation on the ground.
3. After the primer is cured, the bottom layer is constructed with two-component material 3071: accurately metered according to the ratio, poured into component B (transparent material), then poured into component A (with pigment component), mixed and stirred evenly. After that, the black particles and the catalyst are added in a certain ratio (depending on the temperature, etc.), and the mixture is uniformly stirred and then applied. 3071 plus a certain proportion of black particles. Usage: 1.3 kg/m2.
4. The bottom layer can be used to spray the first layer of the surface. Spray the second layer of the top layer in the opposite direction.
Third, matters needing attention
1. Minimize the construction time between each floor, depending on the construction weather and construction conditions on site. If the interval process needs to be increased in cleaning and grinding, the adhesion of the material can be ensured.
2. The surface must be cleaned before each process in the construction process.
3. After the construction of the site is completed, it must be maintained for 5 days before being put into use.
