Beijing kindergarten plastic track

It is located on the edge of Roman Lake in Houshayu, Shunyi with beautiful scenery and convenient transportation. At the same time, it has a group of outstanding management talents and an experienced and high-quality construction team, which provides a strong guarantee for the laying of various sports venues and lays a solid foundation for the creation of first-class classic works.
Construction technology of breathable plastic track
1. Preparation for entering the construction site
Tools: paver and random tools: black rubber mixer, dump truck, push truck, Glue spray machine, glue mixer, scale, power cord, trowel blade, hammer, cement nails, pan ruler,
Pump, polisher, pouring metering bucket, plastic sheet, tape, quartz clock, ruler , slate pen, paint, line box.
, Raw materials: Raw materials and synthetic materials entering the site must pass inspection, including: black rubber particles, red rubber particles, green rubber particles, component A, component B, catalysts, diluents, and barrels
The type and number must be indicated.
Mixing site: In order to facilitate construction and short-distance transportation of raw materials, the mixing site must be chosen at a reasonable location without affecting the construction. The ground should be paved with iron plates or plastic sheets to prevent contamination of the ground.
2. Basic leveling
First, use a three-meter long ruler to measure segmentally. Measure the football field and straight track longitudinally. Measure the arc areas and curves based on the same radius, and use a stone pen to measure. Indicate the recessed area, and the width of each measurement cannot be greater than one meter.
Use the prepared black glue particles, use a straight ruler and a heated trowel to level the depressed area.
3. Paving of the bottom layer
Clean the entire site, first use cut gauze and adhesive to seal the holes on the drainage ditch cover.
First, debug the paver normally, and adjust the height of the trowel plate to the basic ground as required. The entire site should be paved longitudinally from the inside of the football field, and then run.
Use the adhesive added with black rubber particles, and add an appropriate amount of catalyst according to the temperature (add it to the adhesive and stir evenly) and pass it through a mixer and stir for 3 minutes.
Use professionals to operate the keyboard in one hand and hold the trowel in the other to handle the edges. Make sure the operation is correct and there is no leakage, no excess, no overhang, and no shortage of material. It takes two people to spread it. The material is controlled in front of the paving machine to ensure that there is no shortage of material and is uniform and does not affect the normal operation of the machine. A dedicated person is used to use the heating roller to heat and level the machine.
After stopping work, cut off the power supply and carefully clean and clean the paver.
4. Smoothing of the bottom layer
First use a paper knife to cut the gutter eyes. After the black rubber particles are strengthened, use a polisher to carefully and carefully polish the joints and uneven parts of the site. , to ensure that the next process proceeds normally.
5. Spraying of surface glue
First spray the football field according to the laid construction line, and use steel nails to fix the plastic sheet at the red and green overlap to prevent pollution and strictly implement the raw material ratio. Adjust the mixing speed, stir evenly, and ensure that it is transported to the hopper of the glue spraying machine at the fastest speed.
. The glue spraying machine should be monitored by a dedicated person to control the viscosity of the material and the amount of material used in a timely manner. Note that when the sun is direct and the temperature is high in summer, the hopper of the glue spraying machine must be covered with a cover to prevent the thin material from evaporating too quickly.
The person holding the spray gun must have a strong sense of responsibility, control the thickness of the glue as required, and make sure it is uniform and consistent. The ingredients are mixed on the same day and used up on the same day. No downtime is allowed in between to ensure the quality of glue spraying.
. After stopping work, cut off the power supply, carefully clean the glue spraying machine, pipelines, and spray guns with thinner, and place the machine tools at the designated location to prepare for the next day's work.
6. Marking
When laying out the line, carefully check the positioning size. The person holding the line box must check the width every day. It must be guaranteed to be 1 cm wide, align with the empty space, handle it gently, keep it accurate, compact it, and keep it at any time. Clean the wiring box, and no residual paint is allowed
Paint dripping and spray painting personnel must be responsible and responsible to ensure that the sprayed paint is not piled up and is even and uniform. The power supply to the air compressor must be cut off during the lunch break and the end of work in the evening. , Clean the spray gun before finishing the work.

, Tensile strength The national standard B/ (the same below) for tensile strength is. Nano-polyurethane can reach a maximum of 3.
, Elongation at break () The national standard for elongation at break is, nano-polyurethane plastic can reach the highest. In the case of polyurethane adhesive and black rubber particles, nano-polyurethane plastic can reach and still exceed the national standard.
The national standard for compression recovery rate () is compression recovery rate, which can be achieved by nano-polyurethane plastic.
, Service life Nano-polyurethane plastic has a service life of more than one year without adding anti-ultraviolet agents and anti-aging agents.
Weather-resistant nano-polyurethane plastic has strong adaptability to climate change, and its performance is very stable in extremely high temperatures (℃) and ultra-low cold climates (-℃).
Hydrolysis resistance Nano-polyurethane plastic has excellent hydrolysis resistance without adding water-resistant agents.
Moisture-resistant and anti-bacterial properties Nano-polyurethane plastic has very good moisture-proof and anti-bacterial properties and can resist the growth of mold in humid environments.
Flame retardant (grade) nano-polyurethane plastic can reach the national first-class standard without adding flame retardants.
, Stable quality Nano-polyurethane plastic products have stable quality and good performance. The nanomaterials in the glue have a tight physical structure and there is no bubbling during paving, thus ensuring the quality of the construction.
. Anti-skid performance has been tested through practice. Compared with all other similar products, our company's nano-polyurethane smooth adhesive has the best anti-skid performance when exposed to water.
Self-cleaning function Because the nanoparticles are extremely small, the physical structure of nano-polyurethane plastic is extremely tight, making it difficult for dust and other debris to penetrate. It has a strong self-cleaning function and is easy to clean.
. Strong adhesion Nano-polyurethane plastic has the highest strength adhesion to the base material layer, as well as excellent water resistance, chemical resistance, and oil resistance, and can obtain any strength of the combination.
