Nyob rau hauv kev tsim kho ntawm turf football teb, ntxiv rau nteg nyom, lub site kuj xav tau ib co auxiliary ntaub ntawv, xws li quartz xuab zeb thiab roj hmab hais raws li muab tub lim. Tom qab cov khoom siv turf yog nteg, thawj zaug, tag nrho cov teb yuav tsum tau ntim nrog quartz xuab zeb, tom qab combed thiab leveled, ces ntim nrog roj hmab hais, thiab thaum kawg, lub site yuav combed thiab leveled kom uniform filling. Cov tswv tsev feem ntau nug, yog vim li cas cov turf football teb yuav tsum tau ntim nrog xuab zeb thiab hais txog? Hauv qab no, kev sib koom ua ke- tsim cov nyom dag yuav muab cov lus teb ntxaws rau koj.
FIFA described quartz sand as "stability infill" in the test report issued in accordance with its standards. Quartz sand can fill the gaps between the grass filaments. On the one hand, it can make the grass filaments stand upright, with distinct roots and a better rebound effect. The movement of the turf, in addition, to the filling of quartz sand can also prevent the grass from cracking due to friction between the grass filaments due to long-term stepping.
The rubber particles in the FIFA test report are "performance infill", that is, performance filler, as the name implies, to ensure its sports performance. The artificial turf itself also has a certain thickness and elasticity, but in order to meet the needs of sports and to be closer to the sports effect of natural grass, it is necessary to further fill with rubber particles to increase the resilience of the field and absorb vibration to prevent injuries to athletes. Sometimes in order to further achieve cushioning, another layer of cushioning pad is needed under the lawn. In fact, there are many filling materials for granules. At present, rubber granules are mainly used in China, and other materials such as cork are also used in foreign countries for filling, as long as sufficient sports performance can be guaranteed.
Raws li FIFA tus qauv, qhov siab ntawm cov nyom liab qab yuav tsum ncav cuag ntau dua 1/3 ntawm qhov siab ntawm cov nyom, uas yuav tsum tau muab tso rau yuav tsum tsis txhob ntau dhau, tab sis yog tias qhov muab tub lim me dhau lawm, kev ua kis las yuav tsis ua raws li tus qauv. txheem. Yog li ntawd, txhawm rau ua kom tau raws li FIFA cov qauv, cov khoom siv turf ntawm cov khoom sib txawv thiab cov kev txwv yuav tsum muaj qhov sib txawv ntawm quartz xuab zeb thiab roj hmab hais, uas xav kom cov tuam txhab sim thiab kawm hauv chav kuaj. Tam sim no, cov co- tsim cov nyom dag muaj ntau pua cov khoom sib txawv uas tau dhau tus qauv FIFA
