Headstone and other stone protection agent selection

Correct selection of stone protection agents such as tombstones is the key to obtaining the desired protective effect. Generally we must follow and pay attention to the following points:
A: According to the tombstone and other stone protection purposes and requirements of the choice of protective agent, for general stone and other stone tombstone protection treatment, such as tombstones, building walls, usually choose silicone waterproofing agent on it. However, for some special occasions such as hotels or hospitals, stone floors in the lobby are prone to some serious pollution, we must choose to use some fluorine-containing antifouling agents.
    Two: According to the cost of choosing stone tombstones and other stone protective agents, silicone-based protective agents are more economical than fluorine-containing protective agents, and are suitable for selecting tombstones and other stone material application environment and selecting protective agents. Each of the protective agents has its own advantages. And characteristics. Therefore, the performance of the protective agent used must meet the environment in which the stone is used. For example, the protective agent used in tombstones and stone walls must have good acid rain resistance and ultraviolet resistance in addition to good waterproofness. Such as performance, etc. Do not protect agent performance is good or bad, can not be done on the stone to do a few dripping tests to determine, there are surface phenomena to determine the pros and cons of protective agent performance, this simple method is unscientific. Because the waterproof property of a good protective agent is based at least on the basis of sufficient permeability and alkali resistance, it depends not only on the watch but also on the inside.
