In recent years, numerous artificial “green hairs†have appeared on the artificial turf in stadiums of many university campuses across the country. As long as students engage in sports activities on sports grounds, they will be exposed to these “strange things†and shoes. On the trousers, even on the trousers, on the skin, and carelessly sucking in the entrance, the stadium of this school is almost scrapped. The stadium, which was supposed to be a sport for students, turned out to be a health hazard.
Why is artificial grass sports grounds like this? It is understood that this is due to over-reliance on the quality of artificial grass to measure the quality of artificial grass, or simply that as long as the choice of imported grass can create an excellent artificial grass sports field, ignoring the impact The fundamental problem of site quality. In fact, the quality of an artificial turf pitch is a “system engineeringâ€. In addition to the raw material of straw, the quality of the bottom of artificial grass, the technical process of product production, and the paving of foundations of the course also determine the quality of the pitch.
In order to allow a large number of school users to get acquainted with artificial grass sports grounds, the following are the ten possible problems with artificial grass fields and the causes of the problems:
First, artificial grass fiber fade, discoloration?
1. The quality of grass fiber is unqualified, for example, the amount of anti-ultraviolet (UV) agent and anti-aging (amine) agent is too small;
2. The formulation of grass fiber is not scientific, and some additives with poor quality are more;
3. The production equipment of artificial grass fiber is backward, the technology is poor, and the physical performance is unstable;
4. Environmental influences, such as strong ultraviolet radiation in some areas, acid rain, industrial pollution, etc.
Second, artificial grass fiber fuzzing, pilling and powdering?
1. Because of the high frequency of school use, the poor quality of the reticular fibres in 1-2 years, the better quality of 4-5 years will have different degrees of grass fiber split into 50-60 filaments;
2, PP fiber itself is relatively hard, brittle, easy to fluff, pilling.
Third, artificial grass fiber shedding, hair loss?
1, poor production technology, artificial grass bottom cloth, glue quality is poor, resulting in the overall bond to the grass poor;
2, grass fiber using low-end grass (such as PP material), use the middle line to disconnect from the grass;
3, the use of accessories failed (quartz sand particles are too large, not round), causing damage to the grass.
Fourth, artificial grass bottom corrosion, cracking?
1, artificial grass bottom thin, and the use of general PP material;
2. The glue quality used at the bottom is poor or the gluing process is poor, too thick;
3. The foundation level of the site is unqualified and the damage to the bottom cloth of the artificial grass is large;
4, the overall poor drainage, the base fabric soaked in water for a long time.
Fifth, the artificial grass color uneven, serious color difference?
1, artificial grass fiber quality is poor, uneven thickness, color instability, easy to cause different color;
2. Poor installation design of the site, filling of the site with uneven materials, resulting in visual color difference;
3. The foundation of the site is uneven and the joints have obvious marks;
4. Filled accessories are unqualified and the surface is contaminated;
Six, artificial grass site interface is uneven, gap is too large?
1. The groundwork of the site did not meet the requirements of the standard and was not even, resulting in an uneven interface;
2. Improper connection of joints of artificial grass causes unevenness;
3, artificial grass production process and quality problems caused by deformation, can not be straightened, resulting in gaps;
4, lack of professional construction experience, the lack of dedicated construction tools and qualified skilled technicians.
7. The artificial grass field is black and the surface is messy.
1. Excessive or inferior colloidal particles used in the site cause large areas of black pollution;
2. The artificial grass has fallen off from the local multi-point area, leaving only filler material;
3, lack of professional construction experience, lack of dedicated tools and qualified skilled technicians;
4, lack of necessary maintenance after the completion of the construction;
Eight, artificial grass ground floor consolidation?
1, the foundation is not smooth, easy to collect water, soaked for a long time;
2. The used quartz sand and other accessories are too fine or uneven;
3. The used rubber particles, quartz sand and other auxiliary materials have too much impurities or large mud content;
4, artificial grass quality is poor, there is no flexibility and easy to hair loss, and lack of necessary maintenance;
9. The floor of the field is uneven and the artificial grass is sparsely uneven.
1. The foundation of artificial grass field is not smooth,
2. Uneven filling of auxiliary materials; part of the grass seedlings are covered by filling materials during the construction process;
3, artificial grass production process is not professional, there is a greater error in grass height;
4, lack of professional construction experience, the lack of dedicated construction tools and qualified skilled technicians.
X. Artificial grass yard water accumulation?
1. The basic level is uneven and low places are easy to accumulate water;
2, lack of maintenance caused floor knots, poor drainage;
3, local grass fiber wear bad, open into potholes;
4, filling material is not reasonable.
Organ package, also called transaction package, is a kind of document package that is often used in business and office.Because of its internal partition, pull open the same as the organ, so named for the organ package.The organ bag has various materials and sizes, which can be used to store all kinds of office documents in daily office, which is convenient to carry and easy to save.The PP organ bag produced by our company is made of high quality environmental protection and durable PP raw material. Generally, a transparent name card bag is pressed on the front, and the button switch or hand carry is provided for easy carrying.
