Strong weather resistance: the special surface of colloidal particles can resist the pollution of ultraviolet ozone, sulphurous acid and gas, and prolong the service life
.

.
At the same time, it also reduces the investment of foundation funds
.
Temperature also directly affects the viscosity of materials, directly related to the construction quality, so the amount of diluent should be adjusted according to the temperature
.
The spray gun is tilted to 60 degrees to spray in the same direction
.
Some glues are water-based, but when the water vapor is large, the reaction humidity will be accelerated, so it needs to be controlled
.
Nail resistance: it will not be damaged by spikes or starting gear at the 100 meter starting point with the most frequent use of force
.
Temperature affects the speed of chemical reaction
.
Safety: it can prevent sports injury caused by falling
.
After curing for 48 hours, the site can be marked
.
It is suitable for the construction of informal track and field fields in primary and secondary schools
.
Compression resistance: it will not be unable to recover elasticity due to the heavy pressure of track and field equipment
.
The evaporation rate of diluent is determined by temperature, which directly affects the surface effect
.
After the temperature rises, the amount of catalyst should be adjusted properly until the reaction speed is synchronized with the construction speed

The construction of plastic runway under abnormal weather conditions will have a certain impact on the quality of plastic runway
.
Curing and maintenance for 24 hours
.
Weatherability: it will not fade, pulverize or soften due to the pollution of ultraviolet, ozone and acid rain, and can keep its bright color for a long time
.
Then, mix the same amount of EPDM particles with the same size of 1-2 mm into the breathable surface material, and pour them into the spraying machine evenly
.
In winter, the sunshine time is short and the temperature difference is large
.
High elastic rubber particles with particle size of 3-4mm mixed with high-strength single component glue are used
.
In some places, the humidity is high, and the primer directly floats out
.
Because the materials of the plastic track and stadium belong to the mixture of various chemicals, which are formed by a series of chemical reactions, in addition to the materials themselves, the construction environment and the experience of the construction masters also play a decisive role in the construction of the site quality
.
Wear resistance: the wear resistance is less than 2.5%, which can meet the needs of time and high frequency of use of principals at all levels
.
All of these require construction personnel to accumulate experience and deploy diluents according to the weather conditions of the day
.
In order to meet the process requirements, only a small amount of construction can be carried out every day, or the number of construction personnel and equipment can be increased to ensure that the material forming conditions are in the most reasonable period of time
.
All parts should be coated with glue to enhance the ability of scraping the ground and keep the plastic layer away from the ground
.
The intensity of sunlight, the solidification and curing temperature of materials are extremely important, and the intensity of sunlight directly affects the molding temperature of products
.
Adhesiveness: special construction treatment, strong adhesive force, can suppress the rise of moisture, no foaming, peeling and other phenomena
.
For the construction of plastic runway under different weather factors, the construction master should be flexible and strictly control the construction quality
.
This requires good control of construction progress, such as when to start in the morning, what process to do at noon, and when to start curing in the afternoon
.
To control the rhythm, not too much
.

.
Impact resistance: with strong elastic layer and buffer layer, it can absorb strong impact without surface damage
.
Wind speed has a great influence on the evaporation of diluent
.
The reference ratio is 1:6.5, which is evenly mixed and poured into the paver
.
For example, the reaction speed of the middle layer of the plastic mixed runway is too fast to spread out, while the reaction speed is too slow, and the slurry flows down to the bottom layer, resulting in material waste
.
The layer of finished product falls off on site, which may be caused by humidity
.
Construction technology of permeable plastic runway 1
.
After the waterproof material is cured, the bottom layer of runway can be paved
.
Besides the advantages of other forms, the permeable plastic runway also has the advantages of water seepage and air permeability, and can be used all day
.
Impact resistance: moderately absorb foot impact, reduce sports injury, long-term practice and competition are suitable
.
The construction process is simple, in line with international competition standards, and the standard thickness is 13mm
.
When the temperature is high, the material expands
.
When the humidity is high, there will be a certain amount of water vapor on the ground
.

.
Fast construction: due to the use of special materials, the construction of the weather requirements are not high, practical professional construction machinery, shorten the construction time
.
It’s the same in summer
.
Proper elasticity: porous molding material, with moderate elasticity and rebound, can reduce sports injury
.
Sunshine time sunshine time is also very important, affecting the daily workload
.
The reference dosage of waterproof material per square meter is 0.2kg2
.
Economy: convenient maintenance, saving management costs.
.

.
At the same time, the bottom layer will lose its elasticity due to too much filler
.
It is economical, low in price, and will not have bubbles
.
Elasticity: with moderate elasticity and resilience, it can reduce the consumption of physical strength and improve competition results
.
The hybrid plastic runway material adopts the new national standard hybrid structure, the surface layer is Pu particles or EPDM weather resistant environmental protection color particles, and the matrix is full Pu mixed with some rubber particles
.
Humidity is a fatal factor affecting the quality

More details can be found on Wu Xinlong’s website: http://www.cnpaodao.com/ All weather: any season and temperature difference, maintain a high level of quality, can be used after rain, improve utilization
.
But the glue is basically oily, oil-water incompatibility, so that the glue can not penetrate into the ground, inhibit the penetration of the glue, greatly weakening the ability to scratch the ground
.
High cost performance: the surface does not drop particles, the maintenance is simple, and the management cost is saved
.
After spraying and maintenance for 24 hours, spray again in the opposite direction
.
The service life of the breathable plastic runner can reach more than 6 years
.
In the construction process, intermediate materials should always maintain a certain amount of diluent to control viscosity and fluidity
.
Flatness: self leveling materials are used during construction, with flat surface, which can meet the requirements of especially flat competition field
.
Generally speaking, the main runway is 13mm in color, and the auxiliary area is 9mm in thickness, and the color is green

Let’s introduce the main environmental factors affecting the construction of plastic runway: 1
.
Hybrid plastic runway features: all-weather use, any season and temperature difference, can maintain a high level of quality, can be used immediately after rain, increase the utilization time, improve the site utilization
.
After construction, the floor rises and falls directly

The characteristics of the air permeable runway: the bottom layer is made of waste rubber particles bonded by glue, and the surface layer is sprayed with several polyurethane particles mixed with Wang glue
.
The paving thickness is 10mm, curing and maintenance for 24 hours
.
Yunnan plastic runway, Yunnan plastic runway construction five factors affecting the construction of plastic runway analysis, weather and climate is an important factor affecting outdoor construction, plastic runway construction is no exception
.
The reaction is fast at high temperature and slow at low temperature
.

First of all, waterproof treatment should be carried out on the cement foundation, and a layer of waterproof material should be rolled
