人造草坪的填充材料一般为沙或橡胶颗粒，有时也将二者混合使用，在混合使用时，二者的比例依具体情况而定，通常的混用比例为70%橡胶颗粒+30%沙。

Artificial turf filling materials are usually sand or rubber particles, and sometimes the two will be mixed. When mixed, the proportion of the two will be determined according to the specific circumstances. The proportion of the commonly used mixture is 70% rubber particle +30% sand.

过去常使用100%的沙作为填充材料，为的是增加草坪基部的稳定性。

In the past, 100% of the sand was used as a filling material to increase the stability of the base of the lawn.

但是随着人造草坪制造工艺的日益成熟，其基础制造相对已十分完善，所以过去以填充沙来稳定草坪的做法已逐渐被淘汰，现在使用较多的填充方式为100%橡胶颗粒。

But with the manufacturing process of artificial turf is increasingly mature, its manufacturing base has been relatively perfect, so in the past to fill sand stable lawn practices have been gradually eliminated, filling mode is now used more for 100% rubber particles.

填充的沙或橡胶颗粒多为中等大小，而且在填充之前一定要将其洗净。

The filled sand or rubber particles are mostly medium size and must be cleaned before filling.

对于一些冲击强度较大的运动项目如橄榄球、足球等，应适当增加橡胶颗粒的比例，尽量减少运动员的损伤。

For some sports such as football and football, such as football, football and so on, the proportion of rubber particles should be increased to minimize the damage of athletes.

对那些冲击强度小或几乎没有冲击作用的运动场地如网球场等，只要场地硬度均一即可，对缓冲性的要求不高，因此，在填充材料的选择上余地较大。

For those sports venues with little or no impact, such as tennis courts and so on, as long as the field hardness is uniform, the demand for cushioning is not high, so the choice of filling materials is large.

人造草坪中石英砂或橡胶颗粒的填充深度可根据使用目的和所选择的草坪束高度而定。

The filling depth of quartz sand or rubber particles in artificial turf can be determined according to the purpose of use and the height of the selected lawn bundle.
