césped sintético nació en los años 60 del siglo pasado , el uso de métodos artificiales como las materias primas a base de productos de fibra de plástico , no de vida . Sección Grass parece césped natural imitación plana de la tela del césped natural, para satisfacer las necesidades de ejercicio de alta intensidad , de fácil colocación , aplicabilidad y el color brillante , buen tacto , excelente planitud de la hierba y no consumir para la conservación del césped natural del agua , etc [ 1 ] . Sin embargo , el deporte es un deporte perennes , exigir instalaciones deportivas pueden usar tanto tiempo como sea posible en el año . Así césped sintético puede resistir los rayos ultravioletas , el viento , la lluvia y otras condiciones externas adversas , el daño a largo plazo, para ser de buena calidad , larga vida útil . Por lo tanto para mejorar el nivel de tecnología de césped artificial para mejorar la resistencia al desgaste del césped con el fin de prolongar su vida , para jugar un papel más importante en la promoción de la causa de la protección del medio ambiente , desarrollo económico y deportivo.
Utilizado movimiento césped sintético es un material compuesto de polímero , un componente principal es el polietileno es un material no biodegradable , etc , tales como DOWLEX ™ PE y ELITE ™ PE , así como poliolefina AFINIDAD ™ .
Hay muchas ventajas de césped sintético y los materiales de polímero de césped natural debido a la composición del césped artificial tiene muchas ventajas , pero la capacidad de carga de polímero y la mala conductividad térmica , baja temperatura de distorsión por calor , las deficiencias inestabilidad dimensional , por lo que estudiar materiales poliméricos modificados para ampliar es muy necesario su gama de aplicaciones y condiciones de uso ampliado antifricción materiales resistentes al desgaste que mejoran la resistencia al desgaste del deporte césped césped mejorar la vida de su mantenimiento. El método principal para la modificación de las investigaciones existentes : la estructura del polímero modificado , materiales reforzados con fibra de rellenos , micras compuestos inorgánicos de partículas reforzada materiales y nano- partículas modificados . Los tres aspectos siguientes fueron revelados .
Tribología como muy prácticas disciplinas básicas estrechamente relacionadas con la formación y el desarrollo de las necesidades de producción social y el progreso de la ciencia y la tecnología. Desde el siglo en el césped artificial deportivo , tiene características más relevantes que el césped natural, deportes, etc en diversos campos ha sido ampliamente utilizado en las tendencias se convierten en los principales productos para el césped . Por lo tanto el estudio de la resistencia al desgaste del material de polímero del ingrediente principal . Mejorar las características de desgaste del material de polímero , para extender la vida útil del césped sintético , la ampliación del entorno de la aplicación del césped, ampliar las aplicaciones han jugado un papel vital. También se amplió la investigación tribología en el campo de los deportes y de la rápida aplicación de césped artificial , se espera que el césped estudio resistencia a la abrasión artificial para convertirse en una importante rama de la tribología . Pero nuestro fricción bastante tarde futuros trabajadores, tribología necesita el espíritu de la teoría con el Principio práctico para acelerar el estudio de la resistencia al desgaste del césped sintético en China, una importante contribución al desarrollo de la industria del deporte y de la economía nacional.

it experienced a natural grass and artificial lawn behind the contest
When linked together business and sports , the sports competition becomes more and more complicated. The world's first sports football , the commercial impact of factors on sports events is beyond the ordinary imagination, especially in the world of football feast every four years the World Cup , has always been the brightest football world is not simply a hero honor and achievement the dream stage , but also a variety of forces and interests soccer chase fame circus.
When the World Cup in Germany to Italy and successfully ended the fourth cup , the fight for a whole month of players, fans and football practitioners , may be temporarily forgotten due to exhaustion and World Cup 64 games as intense but not necessarily all the wonderful World Cup behind competition. But what is certain is that those that occur during the World Cup of the little-known story behind , will in the future world of football and football related industries have a profound impact , and even about each football player , football practitioners future career direction. During the World Cup in Germany this summer , green grass soccer stage , it experienced a natural grass and artificial lawn behind the contest.
Perfect solution
There is no doubt that German football talent and organizational skills in this World Cup once again be fully demonstrated and affirmed. Not only the German national team achieved third place , and the organization of the World Cup to get high praise from the world , is considered to be the best ever held a session of the World Cup. Artificial lawn planted on the World Cup , the German World Cup organizing committee also expressed their usual rigorous scientific style.
As far as possible reflect the principle of fair play , so that each team are in the "same" under the conditions of competition venues , the FIFA World Cup in Germany requires all venues lawn not only to maintain a high level as the previous , like the World Cup , and the first time ever requires the tournament to be exactly the same turf quality , ie, all located in different climatic conditions in Germany 12 World Cup Stadium grass have to use the same formula, the same planting maintenance technology , the same mowing height and trim pattern, the same turf color, density , so this link from venue teams are the same for each fair. FIFA this requirement if placed in ordinary green lawn, it is very easy to do, because in the natural state, the different blocks in a certain area of lawn light, ventilation, drainage, external factors such as the growth of the lawn is not just the same, and very able to meet the lawn needs , just find a suitable turfgrass varieties can be completely "clone" of many of the same lawn. But in the World Cup Stadium, the situation becomes more complicated, because the German World Cup Stadium are covered , Yu shield high, not only lack of light , poor ventilation , high humidity stadium common problem , and different stadium construction structure is different , resulting in venues light, ventilation , temperature, humidity and other conditions vary considerably , a set of recipes and planting grass seed technology in the past, is basically impossible to adapt to all site conditions , so before the World Cup Stadium turf establishment often used different grasses respond to different combinations of site conditions . Different grass planting of artificial lawn quality is certainly not the same, the effect of competition naturally different .
In addition , the game boring, defensive play has been troubled by the prevalence of international football development problems , to make the game more exciting, more conducive to attack and easier to score, and successive FIFA World Cup Organizing Committee have brains, from the game rules , game ball , site conditions and other aspects of starting and hope to wonderful intense competition to attract fans and sponsors. To achieve these objectives , the FIFA World Cup in Germany in addition to all the requirements of 12 matches exactly the same course turf , but also requires the stadium lawn has fast speed , the ball rolling on the lawn faster , better flexibility , the so-called " fast grass " ," fast ball . " This will minimize the game due to errors caused by site conditions to ensure competitive and exciting game . Although this requirement is not so difficult to achieve before one , but the operation of the technical difficulty is not small, because the lawn has a faster speed to ensure high density factor is the lawn , trim lower , lawn good elasticity , but in insufficient light, ventilation is not Chang stadium as it is not easy.
To achieve these two goals , FIFA and their long-term lawn technical collaborators - the Netherlands, " one hundred green " company conducted a lot of research and, ultimately, to find a suitable grass and technical solutions. "Hundred green " companies, especially for the World Cup soccer tournament developed a special adaptation of lawn turf recipe , this recipe can be fully adapted to the stadium inadequate lighting and poor ventilation , high temperature and humidity unfavorable conditions , so in every World Cup Stadium are growing well. And this lawn density, thin blade of grass can be trimmed to 1 mm low resistance, stampede , with the carpet , the ball by friction is small, scrolling speed, flexibility, and will not change the direction of the athletes step up foot feeling very comfortable, meet FIFA requirements to improve the quality of the game . "Hundred green" this technology last year, also won a famous European Product Innovation Award , the Netherlands Ajax home team pioneered the use of this technology and be successful.
