Hybrid self-forming plastic track, surface layer standard 13mm thick, plastic adopts three-layer composite structure.<br> Mixed type self-forming plastic runway bottom 11mm, self-forming surface 2mm.<br>

Product Introduction:

• The surface is self-grained without solid EPDM particles (non-printing type), the surface layer thickness is 2mm thick, and the texture is naturally formed after chemical reaction after mixing and spraying with pure polyurethane glue with a: B ratio of 1:2;
• The middle layer of 2mm is pure polyurethane glue closed cell foam to form an elastic stable layer, and A: B is 1:4 pure polyurethane glue; The bottom 9mm is a mixed polyurethane adhesive, the ratio of A: B is 1:4, and the content of colloidal particles is less than 25%.

Specificity

1. Self-forming mixed plastic runway construction application characteristics:
2. The surface layer does not contain solid EPDM particles, using special PU material, naturally formed after spraying, wear-resistant, uniform surface texture, clear and full line, scratch resistance field is much better than the particle surface layer;
3. The three-layer composite structure is adopted, and the middle layer is closed-cell micro-foaming technology. Its elasticity, hardness and friction can not only slow down the impact of the impact force on the joints of the human leg when the foot strikes the ground, but also enable the human body to obtain continuous forward kinetic energy. It can achieve the role of shock absorption and rebound, slow down the impact force on the athlete's ankle, knee and other joints, and effectively improve the athlete's competitive level;
4. Uniform texture, good anti-slip, to avoid slipping in running;
5. Good weather resistance, light resistance, excellent water resistance, not easy to aging damage;
6. Weather resistance, light resistance, excellent water resistance, not easy to aging damage
7. Color lasting, not fading, new with time.
8. No particle, no drop particle, strong stain resistance, easy to clean and maintain.

Construction process:

(A) The construction of self-grained mixed primer 9mm (A B 1:4 + black particles) :
The mixture ratio of A: B is 1:4 and black particles (2-3mm) is transported to the pushing site after the material is removed, and the paving should be paid attention to several points: The first is to adjust the proportion of catalyst and diluent at any time according to the temperature change, to prevent the glue from being too thick, the curing time is slow to flow down the slope and cause the phenomenon of internal thickness and external thin, the second is to arrange the paving time as much as possible after 3 PM or before 11 am, to prevent the temperature from being too high, so that the raw material in the curing process foaming phenomenon and affect the quality.

(2) The construction of self-grained cleaning layer 2mm (A B 1:4) :
The cleaning layer is a two-component polyurethane (1:4) (without colloidal particles and powder particles) with a thickness of about 2mm. After the substrate laying is tested to meet the requirements, a layer of self-grained cleaning slurry is coated on the surface of the substrate (the treatment can produce fine pores on the surface of the substrate, so that the bond with the surface layer is more firm and form a whole). The batching process is carried out in strict accordance with the company's technical process, and when the mixing is completed, it is added to the hopper.

(3) Construction of self-grained paste layer 2mm (A B 1:2)
The surface two-component special paste is prepared according to 1:2 requirements, and the surface layer is paved with special equipment. The anti-slip and wear-resistant texture can be formed before the all-polyester glue is completely cured, and the anti-slip effect can fully meet the standards of the International Association of Athletics Federations.

(4) Site marking:
1. After the completion of the surface construction, the site should be scaled up in strict accordance with the latest IAAF line position rules.
2. Determine the distance between the radius points, accurate to greater than the standard distance of 5 mm, the standard steel ruler should consider the tension of the standard steel ruler, temperature difference and the difference of the steel ruler; The range finder should take into account the temperature difference.
3.Measuring straight line with theodolite, measuring arc with standard steel ruler, size accuracy is within 0.5mm, steel ruler should consider the temperature difference, ruler difference and tension.
4. After measuring each point line, determine that there is no problem and start spraying line.
5. Line spraying:
(1) Preparation work: Prepare the equipment and mold used in the spray line, place them in a good position, and place the personnel who clean the mold and spray the line.
(2) Spray according to the regular color of the line position and the put out line.
(3) The technical person in charge and the quality supervisor check the work quality of each spray line worker, and rectify the problem in time.
