鄭州砂巖浮雕如何選擇？金蘭草砂巖浮雕認為，在選擇的時候，可以適當的做些測試：
    Zhengzhou sandstone relief how to choose? Gold Orchid grass sandstone relief that, at the time of selection, can be appropriate to do some tests:

    1、撥水性測試
    1, dial the water test

    我們可以用·手指撥弄水珠使其擴散，然后觀察擴散水珠再次聚集的速度快慢，若再次聚集的速度愈快，表示石材養護劑的撥水性愈佳；
    We can and fingering drops the diffusion, then observe the diffusion of water drops again gathered speed, if again gathered faster, said stone conservation agent dial water more good;

    2、防污性測試
    2, anti fouling test

    在石材表面滴數滴的污染源，如茶、咖啡等，靜置8-12小時后，使用衛生紙擦試并用清水清洗干凈。觀察表面受污染情形，品質愈好的養護劑，污染源愈難滲入石材，因此所造成的污染程度愈低，甚至完全不會造成污染；
    In stone material surface drop a few drops of sources of pollution, such as tea, coffee, standing for 8-12 hours after using toilet paper wipe and clean water. Observation of surface contamination situation, quality as the curing agent, sources of pollution more difficult to penetrate the stone, therefore caused by pollution degree more low, even doesn't pollute;

    經過以上測試，我想會很快知道砂巖的好壞。
    After all these tests, I think it will be very quick to know the quality of the sandstone.
