How to choose high quality artificial turf
The quality of artificial turf is mainly divided into external quality and internal quality. The external quality determines the degree of turf aesthetics. It can be seen by simple methods such as observation and hand touch. The inner quality determines the life and performance of the turf. It is difficult to judge by simple method. It needs to be detected by professional instruments and methods. Before identifying the quality of artificial turf, we need to understand the structure, function and material of artificial turf.
The artificial turf is mainly composed of grass, base fabric and backing rubber. The external quality is mainly grass silk, and the inner quality is largely determined by the neglected base fabric and backing. The grass raw materials are mainly polyethylene and polypropylene plastic granules, which are the same as the mineral water bottles and the raw materials of the supermarket fresh-keeping bags. They are very environmentally friendly. The brand lawn uses the primary particles of large enterprises such as Sinopec. In order to reduce the cost, some cheap lawns will add secondary reclaimed materials during production, but this will greatly reduce the strength, toughness and anti-aging properties of the grass, leading to turf life. Shortened.
In addition, in order to improve the various properties of the grass, a large amount of anti-ultraviolet, anti-aging agent, coloring agent and other additives are added to the grass, and these additives are preferably imported products, the price is very expensive, and the domestic one is much cheaper, but Performance is also very different. Plus not added? What kind of addition? How much? The cost varies greatly, and the quality varies greatly. It is not easy to see from the sample and appearance. We often see that some lawns begin to fade in a short period of time, breaking grass, and even serious when the grass turns directly into fly ash, which is caused by the above two reasons.
After the plastic particles are drawn into the grass, the grass is fixed on the base cloth by a textile method to form a lawn carpet. The base fabric is generally made of high-strength non-woven fabric, which is also very environmentally friendly. The thickness and strength of the base fabric also have a great influence on the internal quality of the lawn. Since the non-woven fabric is relatively soft and cannot guarantee to grasp the grass and maintain the flatness of the lawn, it is necessary to apply a high-strength colloidal material. After the adhesive is solidified, the base fabric becomes a high-strength solid whole--the bottom back. Become the "grass root" carrying grass. Common quality problems such as wire drop, detachment, wrinkling, bulging, and breakage of the lawn are caused by poor quality of the bottom material, resulting in poor "grass root" strength.
At present, the most commonly used adhesive material in China is styrene-butadiene rubber (SBR), which is environmentally friendly and basically meets the requirements of turf quality. At the same time, the cost is relatively low, the technology is simple, and the application is common. The styrene-butadiene rubber of the brand lawn is generally imported using the world-famous "BASF", and the cheap lawns are mostly replaced by cheap domestic lawns. In recent years, polyurethane (PU), a high-performance adhesive material that has appeared in foreign countries, has excellent performance and is technically difficult and costly, and has few applications in China.
