于色差處理辦法的判別，用一個(gè)實(shí)驗(yàn)辦法：將具有色差的兩塊樣品放在清水中，待石材徹底吸水之后調(diào)查，假如兩塊石材在水中的色彩變成了挨近或者相同，此刻只需選用長(zhǎng)臉護(hù)理劑涂刷色彩較淺的石材即可。

To judge the treatment method of color difference, an experimental method is used: put two samples with color difference in clean water, and investigate after the stone absorbs water completely. If the color of the two stones in the water becomes close or the same, just use the long face care agent to brush the lighter stones at the moment.

很多人反響在用長(zhǎng)臉護(hù)理劑條色差的時(shí)分，會(huì)出現(xiàn)色彩發(fā)白，乃出現(xiàn)色彩消失。事實(shí)上，長(zhǎng)臉護(hù)理劑中的有機(jī)硅成分，在石材徹底吸收之后，能夠確保石材色彩在15年內(nèi)不會(huì)發(fā)作太大的改變。

Many people have reported that when using long face care products with color differences, the color may turn white or even disappear. In fact, the organic silicon component in the long face care agent can ensure that the color of the stone does not undergo significant changes within 15 years after it is completely absorbed by the stone.

有機(jī)硅成分的長(zhǎng)臉護(hù)理劑在運(yùn)用的時(shí)分，需求通過(guò)多次的測(cè)驗(yàn)，涂刷長(zhǎng)臉護(hù)理劑，并非一蹴即，而是要根據(jù)涂刷完之后，石材的色澤改變而決議是否繼續(xù)涂刷，在每次涂刷等候長(zhǎng)臉護(hù)理劑徹底浸透的情況下，2遍以上，就能夠堅(jiān)持長(zhǎng)久的運(yùn)用作用。

When using silicone based long face care agents, it is necessary to pass multiple tests. Applying long face care agents is not achieved overnight, but depends on the color change of the stone after application. After each application, waiting for the long face care agent to fully saturate, it can be used for a long time after more than 2 times.

通常情況下色彩均勻的電梯門(mén)套光面石材能夠選用上色技能，假如是比較深、比較淺的色彩較純的石材，等粒結(jié)構(gòu)比較明顯的花崗石，也能夠選用上色技能。而色彩較為雜亂的毛面石材一定要留神運(yùn)用上色技能。

Normally, even colored elevator door frames with smooth stone surfaces can use coloring techniques. If it is a relatively dark or light colored stone with pure color, or a granite with a more obvious equigranular structure, coloring techniques can also be used. And for rough stone materials with messy colors, it is important to pay attention to the use of coloring skills.
