Clean room in the issue of food safety, is a very strict requirements of our country. The production of food, health products on the clean requirements are very high, in the decoration, must ensure the safety and hygiene of food. The characteristics of the clean room to ensure the production of food, health products safety. Biochemical laboratory biochemical laboratory as a scientific research place, for the decoration has high requirements, in addition to the wall decorative materials stable performance, but also requires that the material will not interfere with the biochemical test. General toughened decorative materials, may produce static electricity, affecting the test results. The clean room substrate is made of fiber cement flat plate, which is radiation-free and static-free, and well excludes the interference factors in the biochemical test room. The application of clean room in this field is bound to become more and more extensive. Precision machinery industry, electronic conductor industry, aerospace industry, high-purity chemical industry, atomic energy industry, etc., a variety of high-tech industries on the material dust generation requirements are very high to ensure that the dust-free environment. Clean room wear-resistant, no dust, no radiation and many other characteristics, very suitable for the application of the needs of the field, will certainly occupy a place in such industrial applications. Clean room is an emerging environmentally friendly materials, with many advantages and characteristics, with the progress of science and technology and economic development, the application of clean plate will become more and more widespread.
