In fact, there are many occasions for underground garage. When users decide to make underground garage floor, they will find that there are many kinds of floor, such as concrete floor, cement mortar floor, epoxy floor, wear-resistant floor, terrazzo floor and so on. There are also many suitable ground for underground garage. Users are facing this kind of floor. Often, I don't know how to choose. In order to help you grasp the information of underground garage floor more accurately and quickly, several kinds of floor will be introduced briefly. 一、环氧地坪，环氧地坪技术的是指在已经凝固好的水泥坪上覆涂环氧树脂涂料，覆涂厚度在1-5mm左右，形成一个密闭的有机物保护层。由于环氧树脂是有机物，所以这个保护层具有良好的耐水性、耐油性、耐酸碱性、耐盐雾腐蚀性等化学特性，且平坦无缝、易清洁、易维修保养，是现代工业广为使用的长效地坪材料，广泛用于医药、食品(无菌生产)和电子、化工(防静电)等行业。但是，有机物保护层有几个致命的弱点：
1. Epoxy flooring technology refers to the application of epoxy resin coatings on solidified cement floors with a thickness of about 1-5 mm to form a sealed organic protective layer. Because epoxy resin is an organic substance, this protective layer has good chemical properties such as water resistance, oil resistance, acid-alkali resistance, salt spray corrosion resistance, and is flat, seamless, easy to clean, easy to maintain. It is a long-term effective flat material widely used in modern industry, widely used in medicine, food (aseptic production) and electronics, chemical, etc. Industry (antistatic) and other industries. However, the organic protective layer has several fatal weaknesses.
Hardness and Wear Resistance: Organic materials can not be comparable to inorganic materials in physical properties. Hard resin Mohs hardness is 2-3. Because of heavy moving loads and frequent use of such places as automobiles, forklifts, mobile trolleys, etc., the epoxy resin floor is often severely scratched, causing shell lifting and shedding. Organic materials are polymer, that is to say, under normal conditions such as radiation, light, temperature, polymer chains will break, which is commonly known as aging. The service life of epoxy resin material (epoxy self-leveling) can reach 5-8 years, and the service life of industrial epoxy floor is about 3 years.
2. Wear-resistant floor, hard floor technology refers to: the use of cement or concrete casting process mixed with diamond or other aggregates, the overall solidification. The thickness of hardened layer is about 3-10mm. Because the hardness of aggregate such as diamond is very high, the Mohs hardness of hard floor is 6-7. There is almost nothing in common material that can scratch its surface. So hard floor is hard, wear-resistant, flat and seamless. It can be used not only as floor of industrial workshop, but also as floor of auxiliary facilities such as warehouse, garage and square. . However, the ground generated by this technology is made of cement bonded with diamond sand, so it also has the characteristics of cement products - the surface is bound to form a large number of capillaries after evaporation of water, which have two negative effects on the ground effect:
The diffuse reflection of light can greatly reduce the gloss. Without waxing maintenance, there will be no good visual effect. Absorbing sewage and dust is not conducive to creating clean production environment, and is not suitable for pharmaceutical industry. With the passage of time, the phenomenon of surface weathering of cement products, dust and sand, the general service life of 5-8 years, a short period of 2-3 years.
