In recent years, environmental protection and healthy sports facilities have been increasingly valued and demanded. However, most people often cannot fully identify the difference between environmental protection and non-environmental protection. Below, we will take the artificial turf system as an example to explain how Identify eco-friendly and non-green artificial turf systems.
How to identify environmental protection and non-environmental protection artificial turf
The artificial turf industry, which belongs to ground materials, is really popular because of President Xi Jinping’s emphasis on football. However, the artificial turf market is also mixed with fish and dragons. Let me explain the differences between environmentally friendly and non-environmentally friendly artificial turf systems.
First of all, the current mainstream artificial turf system includes six modules: grass silk, rubber particle filling layer, quartz sand filling layer, base cloth, adhesive, and foundation. Among them, the artificial turf composed of grass silk, base cloth, and adhesive comes from artificial Lawn manufacturer; rubber granules and quartz sand are purchased by the user or the engineering contractor; the foundation is constructed by the user or the engineering contractor, usually cement or sand, and there are almost no environmental problems.
About Grass
The main environmental protection requirements of grass silk are that the heavy metals antimony, arsenic, barium, cadmium, chromium, lead, mercury, and selenium should not exceed the amount specified in the relevant standards. High-temperature masterbatches and processing aids are extruded at one time. Since several raw materials are single, the quality can be well controlled. During use, it will not cause irritation to the skin and will not cause harm to the environment.
Most of the unenvironmental factors of grass silk come from the use of recycled materials with unknown sources or unqualified tests, because the sources of recycled materials are generally complicated and contain many different additives. These additives are easily processed and used many times. React or decompose, causing harm to human body and environment. In addition, due to the different uses of recycled materials, it is inevitable that heavy metals will be introduced during recycling, and they will remain in the grass after being processed into grass silk, causing potential poisoning damage to long-term contacts, and damage to water bodies and soil environments. irreversible harm.
Regarding the different materials of the base fabric
At present, there are only a handful of large-scale artificial turf base fabric manufacturers, all of which have relevant qualification certificates. The quality and environmental protection are relatively reliable, and basically there will be no environmental problems.
The adhesive backing material is different
At present, there are two main types of adhesives used to build lawns: styrene-butadiene latex and polyurethane, of which polyurethane as long as it is a specification for use, will not affect environmental protection in the later stage. The styrene-butadiene latex is made of butadiene and styrene polymerization reaction, and the environmentally friendly styrene-butadiene latex is not only of qualified quality, but also the reaction process is carried out in a precisely controlled reactor to make it meet the national standard. However, this set of processes and equipment is very expensive, not all manufacturers can achieve, only a few large manufacturers, can meet this requirement, so the price of latex of each manufacturer is also different, the quality is also uneven.
Rubber granules use different materials
The significance of rubber granule filling man-made turf is to make man-made turf have natural turf-like elasticity, rolling performance and good interaction performance of man-made grass and ball grass, which is an important component of man-made turf system and the part of the system that directly contacts people. The environmentally friendly rubber granules are made of styrene-butadiene rubber mixed with masterbatch and additives and extruded granulation, and the production process is strictly controlled to ensure the elasticity of the rubber particles, while not containing heavy metals and no peculiar smell. However, rubber granules made by this method are more expensive and are only used in a few venues. Most sites use waste tires, soles, wires and cables and other waste rubber products crushed rubber particles made of rubber particles, due to the complex composition of such rubber, in the process of processing or use between different additives may form a reaction or decomposition to produce toxic and harmful substances, causing harm to users and the environment.
With the popularity of man-made lawns, the impact of non-environmentally friendly man-made lawn systems on human beings and the environment will become increasingly prominent, in addition to government departments need to improve the regulatory mechanism and regulate the market, on the other hand, consumers must also participate in the supervision and make their own contributions to public health and environmental protection.
