The raw materials of artificial lawn include grass silk, bottom and glue. At present, the most common raw material of grass silk on the market is PE, which is also the most cost-effective raw material. Its soft feel, appearance and sports performance are close to that of natural grass. It is also the raw material chosen by most manufacturers now, as well as nylon raw material. This raw material is the best, but its price is relatively high, so it is acceptable to few people. The bottom raw materials are mainly PP bottom, wool bottom, grid bottom and Pu bottom. Now we commonly use PP bottom as the bottom. The binding performance of single-layer PP is poor, which is mainly used for leisure grass, while the double-layer PP is used for sports grass. The durability and corrosion resistance of wool bottom are good, with good adhesion to glue and grass, but the price is twice that of PP bottom. Woven bottom The Department does not use bottom lining, glue directly attached to the fiber root, which is mainly able to meet the sports prohibited by ordinary artificial grass. But at present, there is no production of such a bottom in China. In addition, there is also the bottom of PU, PU has strong anti-aging properties at the bottom, durable, straw line adhesion, and environmental protection without smell, but the cost is too high, it is only the bottom of some high-end products. 。 The raw materials of glue are mainly styrene butadiene latex and PU glue. At present, the domestic glue is mainly styrene butadiene latex with good performance, favorable price and good water melting performance. The binding force of PU glue is better than that of styrene butadiene latex with good durability, but the price is relatively expensive, which is rarely used in China. So the most common raw material of artificial turf is PE + PP bottom + styrene butadiene latex.
The appearance includes (color difference, height, density, row spacing, hand feeling, etc.). The first thing to observe from getting the artificial turf is the appearance, mainly to see whether there is obvious color difference between the lawns, whether the color glossiness is good, whether the height of the grass is consistent with the label, whether the density and spacing of the grass are consistent, etc.
When we purchase, we should first consider the artificial turf that is suitable for our own site, and then consider other parameters. Only in this way can we maximize the utilization. If you are a kindergarten head, then you should give priority to the environmentally safe turf. At the same time, considering the children's own sports situation in the kindergarten, then we can consider buying the artificial turf that is free of filling Laying, no filling lawn can be moved at any time, installation is simple, no filling particles, no maintenance, is very suitable for kindergarten laying. If you are a professional football club manager, what kind of lawn is suitable for your field? High wear resistance, high resilience, and turf with long design service life, then you can choose this kind of artificial turf. Because the operating football field is frequently used, the turf with high wear resistance is the first choice, followed by professional clubs, so the sports performance of the turf is better, so you can choose the most wear-resistant diamond monofilament grass + safety damping layer, such as Match with the requirements of professional club, its sports performance is very close to the natural grass, and wear resistance is good, can be used in high frequency.
