Magnesium oxide fineness, ensure uniform, otherwise if there is heating out of sync, it is easy to make the board deformation. Light burning powder in the color of the white color of the ventilation duct, the color of magnesium oxide should be slightly white as far as possible, in order to achieve a beautiful effect. Also some manufacturers do not notice the color of magnesia. The activity of magnesium oxide is also very key, activity, control in more than 55% on the line, activity is too high, easy to lead to reflect too intense easy to make the middle of the benzene plate (foam plate) deformation. Some manufacturers do not put benzene plate, in the choice of magnesium oxide, content activity is not too high. Magnesium oxide fineness, ensure uniform, otherwise if there is heating out of sync, it is easy to make the board deformation.

Magnesium oxide has a good ability to withstand different environments, magnesium oxide after light, heat and cold, wind and rain, bacteria and other comprehensive damage, the product basis is intact. Products added magnesium oxide, look high gloss, full color, good toughness, smooth appearance, not easy to damage, the overall quality of the product improved.

Originating in Japan, 6S is an activity of effectively managing production factors such as personnel, machines, materials, methods and information on the production site. Adding molten steel and magnesium oxide is an activity to constantly organize, rectify, clean, sweep, improve quality and safety of each production element in the production site. 6 s activity, first of all, to distinguish the necessities in the process of production with the necessities, disposal of discretionary regularly, housekeeping management necessities, number clearly and accurately identified, save search time, through cleaning, floor clean and tidy, improve staff quality, eliminate accident hidden danger, ensure employees' personal safety, yingkou light burning powder, ensure normal production. The implementation of 6S activity is an important means to manage the production and operation site. It is a long-term and arduous activity, which requires the joint participation of all staff and continuous promotion and innovation.

A good environment can be imperceptibly influenced. If we pay attention to details everywhere, it will affect employees' working attitude and quality control. Therefore, the environment itself is also a kind of productivity. 6 s activity object is the scene of the "environment", it to comprehensive consideration of global production site environment, and make feasible plans and measures, it through the sorting, reorganization, cleaning, cleaning, quality, safety, saving and other activities, eliminate the production site of various unfavorable factors and behavior, reasonable use of time, space, energy and other resources, to play its greater efficiency, So as to create an efficient, make the best use of the workplace, to achieve standardized management, ensure the smooth completion of production tasks, and ultimately achieve the enterprise with low cost, to achieve great benefits. Therefore, 6S management is an important means for enterprises to improve work efficiency, reduce operating costs, ensure quality and delivery time, and is an essential tool for enterprises to adapt to market competition. Enhance product quality and enhance the core competitiveness of enterprises.
