一、What is an artificial lawn?
Artificial lawn refers to artificial turf, which is made of a special simulation material. It looks as much as real grass, but has many advantages. Artificial lawn is divided into injection molding artificial lawn and woven artificial lawn.
The injection molding artificial lawn adopts the injection molding process, the plastic particles are squeezed in the mold, and the bending technology is bent, so that the grass leaves are equiometric and arranged regularly, and the height of the grass leaves is completely unified. Suitable for kindergarten, sports field, balcony, greening, sand gold and so on.
The woven lawn is a like synthetic fiber, implanted in the woven base cloth, and the back is coated with a fixed coating for artificial lawn on the sports field, leisure field, golf field, garden floor and green ground.
二、What are artificial lawns according to their use?
With the development of artificial lawn products, artificial lawn began to be divided by category, artificial lawn can be used according to the use
Divided into the following categories:
Sports lawn: specially designed for a variety of sports fields, such as football fields. This kind of lawn has good wear resistance, impact resistance and elasticity, can withstand the high intensity of sports activity, and provide good court performance.
Landscape leisure lawn: mainly used for landscape and leisure areas, such as parks, gardens, courtyards, etc. This kind of lawn is characterized by realistic appearance, soft and comfortable, with good ornamental and comfort, but also easier to maintain.
Enclosure green lawn: mainly used for enclosure and greening decoration, such as wall, guardrail, etc. Such lawns usually have a higher density and longer fiber length to form a continuous and uniform green cover, which beautify the environment, isolate noise and isolate the line of sight.
Golf course lawn: an artificial lawn specially designed for golf courses. This type of lawn usually has high smoothness, controllable ball speed and rolling characteristics to provide a high quality golf experience.
These classifications are based on the specific uses and characteristics of artificial lawns, and different classifications are suitable for different occasions and needs. With the continuous progress of technology, there may be more types of artificial lawn suitable for specific occasions and uses. When buying artificial lawn, you should buy according to these types.
三、How to lay artificial lawns?
1.Artificial lawn laying is relatively simple, and the laying process mainly includes the following steps:
- Basic preparation: clean the site to ensure that the ground is flat and free of debris and weeds. Conduct the site survey according to the design drawings, and specify the laying scope and direction.
- Foundation treatment: excavate the foundation of 5-10 cm deep, lay a layer of coarse gravel or gravel, the thickness of about 3-5 cm, to ensure good drainage.
- Laying horizontal layer: lay fine stones or sand on the gravel layer, the thickness of about 2-3 cm, is used to adjust the ground smoothness. Use a roller to press the foundation to ensure that the ground is solid and smooth.
- Laying artificial lawn: cut artificial lawn coil material, lay according to the predetermined direction and location, and pay attention to the consistency of grass wire direction. Precision the joint and use special adhesive to ensure that the joint is smooth and firm.
- Filling material: Fill the lawn surface with appropriate quartz sand or rubber particles to improve stability and cushioning.
- Check and clean up: check whether the lawn surface is flat and whether the joints are tight. Clean up all the debris generated during the construction process and complete the construction.
2.During the construction process, the following matters should also be noted:
- Ensure the cleanliness of the foundation site. If there is any garbage and debris on the foundation ground, it must be cleaned up first.
- Use the measurement tool to accurately measure the field size and control the error within the allowable range.
- In the construction process of artificial lawn bonding technology, to ensure that the glue daub evenly, bonding alignment, there can not be dislocation phenomenon.
- The construction temperature of artificial lawn should be controlled at 0-40℃, and construction is prohibited in rain and snow weather.
- When the lawn is laid, the arrangement direction of the lawn should be consistent with the direction of the light to ensure the beauty and reality.
- The artificial lawn site has high drainage requirements, which should be tilted 6-8 ‰ from the center to the parties of the southeast and northwest, so that the water can be drained quickly.
The above steps and precautions can help ensure the quality and effect of artificial turf laying.
四、 What parameters determine the quality of an artificial lawn?
The quality of the artificial lawn can be measured by many aspects of the parameters. The more expensive the artificial lawn, the better the parameters, the more expensive the lawn is.
I will list the common and mainly easy to understand parameters of artificial grass for your reference:
- Grass height: the height of the grass line from the bottom back to the terminal, measured in mm.
- Grass fiber material: polyethylene (PE), polypropylene (PP), nylon (Nylon), etc., in which the PE material feels soft, the appearance and sports performance is close to the natural grass.
- Grass fiber fiber: grass fiber is special (dtex), the conventional specifications are 6300,7400,8000,8800,9500,10000,11000, etc., the greater the coefficient, the heavier the weight, the better the quality.
- Density: refers to the number of tufted needles per square meter, such as 9,450 needles / m².
- Line spacing: the distance between the line and the line, in inches, common 3 / 4 inch, 3 / 8 inch, 5 / 8 inch, etc.
- Number of needles: the number of tufted needles per meter, such as 10 needles / 10cm, then it is 100 needles per meter, the more the number of needles indicates that the greater the density of the lawn, the better the quality.
- Bottom back: artificial lawn bottom material, generally have PP, wool, PU, knitting and so on.
- Back glue: the glue on the back of the lawn, usually using styrene-butadiene latex, etc.
- Service life: the longer the life, the better the quality, usually 8-10 years.
- Prices for artificial lawns
I have collected data on the price of artificial lawn in the six countries with the lowest and highest prices in the world, which can provide a reference for us to purchase artificial lawn.
The data are as follows:
- India: $10 – $20 / sqm
- China: $15 -$25 / sqm
- Eastern European countries: $20 -$30 / sqm
- USA: $40 -$100 / sqm
- UK: $35 -$80 / sqm
- Australia: $45 -$90 / sqm
The above data show the global distribution of artificial turf prices, which are mainly affected by local market conditions, material costs and labor costs.
