The energy supply of the non-igniting ground mainly emphasizes that there will be no sparks due to friction and impact during use, so as to avoid fire, ** and other dangers. This type of flooring is usually made of metal or alloy materials, or specially treated materials such as concrete, terrazzo, etc. Its main purpose is to prevent safety accidents caused by sparks, and it is mainly used in places with high safety requirements, such as chemical plants, oil plants, gas stations, etc.
There are two main ways to do it without igniting the ground. One is to use a specially proportioned mixture to evenly spread on the concrete surface of the initial setting stage, which is composed of a certain particle gradation of non-pyrophoric mica aggregate, special cement, other admixtures and admixtures. The other is cast-in-place, which requires ensuring that the material is clean and as homogeneous as possible when mixing.
Specifically, the construction technology of adopting a special ratio material to spread the concrete surface in the initial setting stage comprises: when the base concrete is dry before 5 6 is dry, the aggregate is spread and strives to be uniform, and the sprinkling material is carried out in two times, and the amount is guaranteed;
After the initial setting, wipe it with a calender;
Check the flatness of the sprinkling and wiping, adjust the material in time for the low-lying places, and then compact and rub the hair and wipe the place;
Before completion, it is polished with a trowel.
For on-site pouring construction, it is necessary to ensure that uncleaned materials and appliances are not used on the site, so as to avoid the impact of man-made material mixing on the non-ignition performance of the surface layer. Of course, the flatness and smoothness of the final surface layer also directly affect its performance requirements, after all, the smoother and smoother it is, the friction will not produce much, and it is not easy to produce sparks.
The above are the two main practices of non-igniting ground, and the specific construction steps and precautions may vary depending on the engineering requirements and local specifications, so it is necessary to refer to the relevant standards and regulations in the actual construction. It is important to note that non-flammable floors and anti-static floors are often confused, but they have different properties and uses. Now let's introduce the anti-static floor, which mainly focuses on the ability of the ground to effectively conduct static electricity, so as to avoid the harm caused by the accumulation of static electricity and discharge. This kind of floor is made of materials with good conductive properties, such as conductive rubber, conductive terrazzo, etc. Its main purpose is to reduce the accumulation of electrostatic charges and protect equipment and personnel from damage caused by electrostatic discharge. So, while both non-flammable floors and anti-static floors are designed to improve the safety of the floor, their focus and function are different. But if it is a non-igniting ground and a non-igniting explosion-proof ground, it is basically the same ground system.
