1. The size of each roll of lawn is the same, so why does it vary in length on site? Is it a problem of production?
A: Regarding the problem of different lengths of grass rolls mentioned, there are several situations as follows:
1. In general, there are different lengths of the grass rolls, and the length of the grass rolls will be longer than the actual size. This is because our company can design drawings for you for free before production, according to the actual size of your site. The company's standard is 50CM for 72 meters, which prevents the artificial grass from shrinking due to temperature and other reasons.
2. Factors for shortage of grass roll length on site include:
A. There is A discrepancy between the size on site and that on the drawing, and the size on site is larger than that on the design drawing;
B. Slope error of the foundation. Generally, the length and size of the football field will be longer than that specified in the drawing due to the use of tortoise back or slope drainage;
C. Thermal expansion and cold contraction, the large temperature difference causes serious shrinkage and shortening of the lawn;
D. Wrinkle and pavement cannot effectively pull equality;
E. Steel ruler must be selected as the measuring tool. If a tape ruler is used, there will be a large deviation.
2. Why are there certain differences in buying grass yarns every time? What are the reasons for this?
Answer: there are batch differences, this is also a normal phenomenon. Because the batches are different, there will be some slight differences in color, etc., but the products of the same batch will not appear this kind of phenomenon, which has nothing to do with the quality of grass silk.
3. Why the wastage is 50 square meters more than the wastage I ordered from other enterprises?
A: When we designed the drawings, we made lap joints between coils (the standard for lap joints is 10M, while other manufacturers may not design lap joints, so the loss calculated by them will be relatively small. The advantage of lap joint is that it can minimize the problem of excessive joint between the roll and the roll when the site construction is brought about, and the disadvantage is that the loss will be slightly larger. If you do not need to do lap, our loss is the same as other enterprises.
4. Why is there a lot of grass at the bottom exposed? Is it because your company wants to save material, will it affect the quality?
A: The main reasons for the grass on the outside of the base cloth are as follows:
1. When glue is smeared on the grass fiber, part of the fiber is exposed green, which does not affect the binding force of glue on the grass fiber, nor will it affect the product quality of artificial grass. Artificial caocao wire itself is smooth surface, and in order to improve the ability of tufted and oily coating layer in grass fiber surface, so the surface of the glue and yarn bonding strength is very weak, so even at the bottom of some adhesive glue no dew on the grass surface outside, you gently scrape can be scraped off with the hand, is only a matter of sense, does not affect the actual quality of the product.
2. There is no requirement for the bottom appearance of artificial grass in the relevant national standards and FIFA standards. The binding force is required to be greater than or equal to 30 Newtons:
5. Why does the bottom crack appear once the sample is folded? Is it a quality problem?
A: Regarding the cracking problem at the bottom, the reasons are as follows:
1. If you fold the artificial grass products in half, there will be cracks at the joints between the grass silk and the base cloth, which is a normal phenomenon.
2. The reason for the bottom cracking is that the glue is too thick when backing, so it is easy to crack after folding in half. The role of glue binding grass, in order to increase the binding force of grass, so some products gum will be thick. Artificial grass paving is tile, will not occur in half the phenomenon of folding
6. Why is there a big difference in color between the sample and the lawn on site?
Answer: we strictly in accordance with the IS09000 quality standards and artificial grass purchase and sale contract in both sides of the product technical parameters production, there is no jerry-built behavior.
As for the occurrence of grass fiber goods wrong version of the phenomenon of possible reasons are as follows:
1. Since the production batches of grass fiber are different, it is normal to have slight differences in the color of grass fiber, so it is possible to have slight differences in the color of samples and goods. Our company can guarantee that the same batch of artificial grass products will not have color difference and other phenomena.
2. The sample has been placed for a long time, but the finished product has not been produced until then, resulting in a long time difference.
3, grass fiber lodging order is different, will also cause differences; Through carding will be effectively improved;
7, how to store artificial grass for a long time without affecting the quality?
Answer: 1, if the artificial grass products have been delivered to the site, it is recommended that you find an indoor storage. At the same time, it is best not to stack more than 3 layers, because over time, it is easy to cause the deformation of artificial grass.
2. If there is no indoor storage condition and it needs to be stored in the open air, it is recommended that you put the bottom pad high to avoid being soaked by rain when it rains. If conditions permit, you can cover it with a rain cloth.
8. Why is the glue purchased by the drawing design not enough when it is laid on the site?
A: The reasons for insufficient glue are as follows:
1. When designing the drawings, we calculate according to the estimation of the construction experience of the engineering department, because there will be some differences between the design change or other objective reasons on site and the actual amount on site.
2, the site construction, because each construction master construction habits are not the same, the loss is large or small, or the basic inequality itself, will also cause glue is not enough.
3, the weather temperature is low, such as less than 15 degrees, affect the fluidity of glue, will also increase the amount;
