Detailed explanation of the application scope and

Plastic track is also known as all-weather track and field track and field track and field track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives and fillers. New materials are widely used. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which is conducive to the athletes' speed and technology, effectively improve sports performance, and reduce the fall injury rate. Plastic track is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain UV resistance and aging resistance. It is internationally recognized as the best all-weather outdoor sports ground floor material

I. characteristics of plastic runway:

all weather use: it can maintain a high level of quality in any season and temperature difference. It can be used immediately after rain, increase the utilization time and improve the utilization rate of the site

elasticity: it has moderate elasticity and rebound, which can reduce physical consumption and improve competition results

impact absorption: moderately absorb the impact of feet, reduce sports injury, and it is suitable for long-term practice and competition

weather resistance: it will not fade, pulverize or soften due to UV, ozone and acid rain pollution, and can maintain its bright colors for a long time

wear resistance: the wear resistance is less than 2.5%, meeting the needs of school principals at all levels for time and high frequency of use

compression resistance: it will not be unable to restore elasticity due to the heavy pressure of track and field equipment

nail resistance: it will not be damaged by spiked shoes or starting gear at the starting point of the 100m with the greatest force and the most frequent use

&emsp vulnerable part 1: sensor; Impact resistance: it has a strong elastic layer and buffer layer, which can absorb strong impact and will not damage the surface

Flatness: self leveling materials are used during construction, and the surface is flat, which can meet the requirements of a particularly flat playing field

adhesion: special construction treatment. Sometimes, the bonding force is also strong in casting structure (cast steel, cast aluminum, etc.), which can suppress the rise of water content, without blistering, peeling and other phenomena

safety: it can prevent sports injury caused by falling

Economy: convenient maintenance and saving management costs

II. Types, material structures and characteristics of plastic runways

plastic runways can be divided into prefabricated plastic runways, mixed plastic runways, breathable plastic runways, composite plastic runways, etc. according to their different materials and construction methods. These types of plastic runways are explained in detail below

prefabricated plastic track

it is prefabricated with composite rubber and natural rubber as raw materials and special processes of calendering, vulcanization and stable treatment. The product fully considers the biomechanical needs of athletes in the design process: the three-dimensional internal structure makes the track have excellent elasticity, strength, toughness and shock absorption effect, and effectively reduces muscle fatigue and micro damage of athletes. It has the remarkable characteristics of constant performance, simple installation and green environmental protection

1. Scope of application: applicable to domestic and international track and field competition venues at all levels, training venues, as well as various school competitions and teaching venues

2. Main materials: Prefabricated environmental friendly rubber runway coiled material (13 mm thick, 1.22 m wide, length can be any length), special adhesive

a. pure natural rubber coiled material, factory prefabricated, high temperature and high pressure manufacturing process

b. The bottom design adopts the best geometric design, and its bending can be changed arbitrarily, so that the maximum impact force can be absorbed and the maximum energy can be returned

c. The surface design adopts concave convex surface to ensure that rain water will not stay on the main contact surface in any weather conditions and will not affect the friction force

mixed plastic runway

adopts the mixed structure approved by the IAAF. The surface layer is Pu particles or EPDM weather resistant environmental protection colored particles, and the parent body is full Pu mixed with some rubber particles. The construction process is simple, in line with international competition standards, and the standard thickness is 13mm. It has the advantages of good elasticity, skid resistance, wear resistance and so on. It is widely used in large and medium-sized track and field fields at home and abroad

features: it can be used all day, maintain a high level of quality in any season and temperature difference, and can be used immediately after the rain, so as to increase the utilization time and improve the utilization rate of the site

breathable plastic runway

is made of recycled rubber particles mixed with one component glue and paved mechanically. Low cost, breathable and permeable

the breathable plastic field is paved by mixing the rubber particles with PU glue (the amount of glue used is small), using the method of mechanical paving. After the glue is cured, spray the mixture of PU glue and fine Pu particles (or EPDM particles) with special glue spraying equipment, and spray it on the surface of the paved plastic field. This site is characterized by good flatness, good elasticity, high safety, low cost, low construction difficulty, easy popularization, and is suitable for non professional training, competitions, and schools

it is applicable to universities, primary and secondary schools all over the country, and the climatic conditions are above -16 degrees, not applicable to alpine ice and snow areas

composite plastic runway

composite runway is divided into two types. One is to use the elastic layer of breathable runway to pave mm, and the surface layer is paved with EPDM particles for mm. The paving method is the same as that of the elastic layer. This process is simple to construct, but the surface layer is relatively flat, which is more suitable for the stadium and is generally not adopted

the other is a combination of breathable runway and hybrid runway, that is, the runway made of the elastic layer of breathable runway and the surface layer of hybrid runway, which is generally applicable to the situation that the foundation is cement concrete foundation, and the surface layer is required to be like hybrid runway

features:

1. It has air permeability function. Under high temperature, the steam generated by the foundation will be quickly emitted, and the steam pressure cannot be accumulated, so it will not produce bubbling phenomenon, and meets the professional requirements a - box surface classification coefficient;, Good elasticity

2. The surface layer adopts EPDM particles to make it highly UV resistant. Practice has proved that it can be used for more than ten years without fading concerns

3. Strong wear resistance. Even if thousands of students use it for 10 hours a day, it can remain in excellent condition after 10 years

the composite plastic track is applicable to all kinds of schools and professional stadiums at all levels, track and field runways, semicircle areas, auxiliary areas, national fitness paths, indoor gymnasium training runways, playground road pavement, etc

summary:

prefabricated plastic runway and fully plastic plastic runway are high-end products with excellent performance. Of course, the price is also the highest. Professional track and field stadiums are generally built, which is quite high for general primary and secondary schools

hybrid plastic runway and composite plastic runway have higher requirements for foundation, medium performance and moderate price, but they are also much higher than breathable ones

the performance of breathable plastic runway can fully reach gb/various indicators, and it is breathable and permeable, with short construction period and easy maintenance and renovation. It has incomparable price advantages and is the first choice for all kinds of primary and secondary schools. EPDM plastic runways are mainly used for non-standard runways such as primary schools or kindergartens
