Study Of Physical And Chemical Properties Of The Modified Solid Surface

Along with the development of high and new-technology, requirement on characteristic of material becomes higher and higher. Surface modification technology has been developed during the study on surface protection and surface strengthening. Surface modification technology includes changing on physical property and chemical property of material, the aim is to improve characteristic of material. Surface modification technology is one kind of methods of economizing energy sources and resource. Generally speaking, it is take place from surface such as corrosion, oxidation, abrasion and wear. Surface modification technology is more and more important not only in chemical but also in interphase engineering.Surface modification is accomplished by chemical reaction and chemical adsorption. This is the common method in production now.The paper consists of two sections:I. Relationship of change in friction and chemical reactions of polished granite surface.The polished surfaces of granite would become slipper in contact with water. The reaction between a colorless, odorless, water-soluble composite organic-silicon compound and the polished surface of granite would improve the anti-skid property and increase friction without changing the polished surface of granite. Because of it s low surface tension and surface energy, various waterproof agents can be made from the composite organic-silicon compound. Composite organic-silicon waterproof agents can form a waterproof film by reacting with the granite surface. With the change of granite surface property such as wetting, counter freezing, electrical property and micro-appearance, the friction force of granite surface also changed.II. Separation without pollution on contaminated soil by oil There are many attempts been made to stabilize the contaminated soil. It was found that the pollution and damage with different degree were occurred in the treatments. The active agent was made in order to avoid damage or pollute. The effects of this treatment including: displacing oil, anti-swelling and demulsify. At last,the oil had no water,the water had no oil,and there were little oil in clay.
