1、于色差处理办法的判别，用一个试验办法：将具有色差的两块样品放在清水中，待石材完全吸水之后调查，假设两块石材在水中的颜色变成了挨近或者相同，此时只需选用露脸护理剂涂刷颜色较浅的石材即可。

1. For the discrimination of color difference treatment method, a test method is used: put two samples with color difference in clean water, and investigate after the stones fully absorb water. Assuming that the color of the two stones in the water has become close or the same, at this time, just use the exposed face care agent to paint the lighter stones.

2、很多人反应在用露脸护理剂条色差的时分，会呈现颜色发白，甚呈现颜色消失。事实上，露脸护理剂中的有机硅成分，在石材完全吸收之后，可以保证石材颜色在15年内不会发作太大的改动。

2. Many people react that when using facial care products with color differences, the color may turn white or even disappear. In fact, the organic silicon component in facial care products can ensure that the color of the stone will not undergo significant changes within 15 years after it is fully absorbed by the stone.

有机硅成分的露脸护理剂在运用的时分，需求通过多次的测验，涂刷露脸护理剂，并非一蹴即，而是要根据涂刷完之后，石材的色泽改动而抉择是否继续涂刷，在每次涂刷等候露脸护理剂完全浸透的情况下，2遍以上，就可以坚持长久的运用作用。

When using silicone based facial care agents, it is necessary to pass multiple tests. Applying facial care agents is not an overnight process, but rather a decision to continue based on the color changes of the stone after application. After each application, wait for the facial care agent to fully saturate, and apply it more than twice to maintain a long-lasting effect.

3、通常情况下颜色均匀的电梯门套光面石材可以选用上色技术，假设是比较深、比较浅的颜色较纯的石材，等粒结构比较显着的花岗石，也可以选用上色技术。而颜色较为杂乱的毛面石材一定要留心运用上色技术。

3. Normally, for elevator door frames with uniform color, coloring technology can be used for the smooth surface stone. Assuming it is a relatively dark and light color of pure stone, or a granite with a prominent equigranular structure, coloring technology can also be used. And for rough stone materials with mixed colors, attention must be paid to the use of coloring techniques.
