常用脱模剂，目前市场上的品种很多，它在构件砼形成中，易出现剥皮、脱落、露砂、锈斑等不良现象，直接影响了砼构件的外观和耐久性，为此，要使砼达到镜面效果，我们需要这样一种脱模剂：
There are many kinds of demoulding agents commonly used in the market at present. During the formation of component concrete, it is easy to peel, fall off, expose sand, rust spots and other adverse phenomena, which directly affect the appearance and durability of concrete components. Therefore, to achieve mirror effect of concrete, we need such a demoulding agent:
①具有最基本的脱模功能，
① it has the most basic demoulding function.
②在砼构件成型后，表面必须高密度光洁，其平整度可与镜面玻璃相比，
② after the concrete component is formed, the surface must be high-density and smooth, and its flatness can be compared with mirror glass.
③砼构件成型后，在砼表面形成钢化型保护层，其硬度超过砼内在强度。
③ after the concrete component is formed, a steel protective layer is formed on the concrete surface, and its hardness exceeds the internal strength of the concrete.
传统的机油，其粘性及稠度高，气泡不容易溢出造成拆模后表面出现气孔，并且严重影响后续表面抹灰砂浆与混凝土基层的粘结力，影响工程质量。这里就不多说水性混凝土脱模剂和油性混凝土脱模剂了，相信大家百度一下也会搜出很多关于水性脱模剂和油性脱模剂区别的资料。
Traditional engine oil has high viscosity and consistence, and bubbles are not easy to overflow, resulting in air holes on the surface after formwork removal, which seriously affects the adhesion of subsequent surface plastering mortar and concrete base, and affects the project quality. There is not much to say about the water-based concrete release agent and oil-based concrete release agent. I believe you will find a lot of information about the difference between water-based release agent and oil-based release agent in Baidu.
