一，硅PU球场施工面层不统一。硅PU球场具有绿色环保、弹性适中、经久耐磨的性能特点。在施工前一定要检查硅PU球场的面层是否统一，如果在没有保证统一面层的情况下就进行施工，很有可能会导致面层的变色。
A silicon PU course construction, the surface layer is not uniform. Performance characteristics of silicon PU course with the green environmental protection, moderate elasticity, durability. Before construction must face layer of silicon PU stadium is a unified examination, if in no guarantee construction unified surface layer, is likely to lead to surface discoloration.
二，硅PU球场的材料质量得不到保证。硅PU球场在市场上销售范围非常广泛，已经被众人所熟知，但有些商家为了谋取利益，拿一些便宜的劣质产品在市场上销售。这种廉价的劣质材料在进行施工的时候发生变色，甚至会发出有刺激性的臭味。严重危害使用者的身体健康。
Two, silicon PU course material quality can not be guaranteed. Silicon PU Stadium on the market range is very wide, has been well known, but some businesses in order to seek interest, get some cheap low-quality products sold in the market. This cheap inferior materials change color when construction, and even will be issued with a pungent odor. Serious harm to the health of users.
三，硅PU球场与容器发生化学反应。可能是硅PU材料中的清漆中酯类溶剂遇水后铁质的容器发生反应，或者金银粉与清漆发碰撞酸蚀作用，最后导致材料颜色变绿、变黑，看起来黯淡无光，没有一点光泽。
Three, the silicon PU stadium chemical reaction with the container. May be the esters solvent water silicon PU material in the varnish iron container after reaction, or gold and silver powder and varnish hair collision acid inhibition, finally causes the material color becomes green, black, looks intense darkness without light, not a little luster.
四，硅PU球场材料储存时间太长。如果硅PU球场放置的时间太长，没有在规定的时间内开启，底部的材料会出现沉淀现象，进而导致硅PU球场发生变色。
Four, storage silicon PU course materials for too long. If the silicon PU stadium placed too long, not open within the prescribed period of time, at the bottom of the material will appear precipitation phenomenon, resulting in silicon PU course of discoloration.
