The production line of sanded mgo board needs to meet the requirements of complete functions, professional equipment and complete specifications. From material preparation to factory inspection, every process must be strictly implemented to ensure the stable output of product quality.
What is the production line process of the sanded mgo board?
How to choose sanded mgo board according to material properties?
How to choose sanded mgo board according to chloride ion content?
Material preparation: magnesium oxide, magnesium chloride, perlite, non-woven fabric, glass cloth, sawdust, and water are put into the mixer after quantitative measurement to form raw material slurry.
Forming and conveying: the non-woven fabric and glass cloth are uncoiled and then enter the forming machine. The mold is placed on the platform of the forming machine and is ready for use. The slurry of the mixer falls on the mold and enters the forming machine, and extrudes the glass magnesium plate of the required specification on the forming machine. , and then cut into required lengths, and distributed into the oxidation chamber for oxygen protection through the transit transverse system.
Dehalogenation: Soak the oxidized sanded mgo board in water for dehalogenation.
Trimming: The sanded mgo board after dehalogenation is processed by an automatic trimmer to complete the fixed-length trimming, packaging and stacking of the glass magnesium board. After the stacking is completed, it is transported to the packaging area by a forklift for inspection and packaging, and the complete production line process is completed.
In the production process of sanded mgo board, to control the flatness of the product and not to deform It brings a lot of troubles and its negative effects, and it is also a relatively common contradiction in the market. The so-called corner-cutting situation at the expense of product quality because of cost savings and production cycle The customer makes a clear comparison on price and quality.
Chloride ion content: At present, most parts of the world have made clear regulations on the chloride ion content of sanded mgo board, and the proportion should not exceed 10%. Because the chloride ion content is too high, it will cause the product to effluent and return to moisture, which is also called return to halogen in the industry. Because once the product returns to halogen, it is impossible to continue to use it, it must be removed and replaced, and there is no other remedy. Therefore, preventing the return of halogen is the first priority to identify the quality of the fireproof board. The products that will return to the halogen are worthless products, no matter how beautiful their appearance is, there is no real meaning.

magnesium oxide board has a wide range of applications, especially for partition walls and ceilings in architectural decoration. It is fully suitable for thermal insulation structures, sound insulation walls, wet areas, movable partition walls, super fire protection, fire door plywood and other fields.
What are the main features of the magnesium oxide board?
What are the main raw materials of magnesium oxide board?
What is the reason for the popularity of magnesium oxide board in the market?
1. Magnesium oxide plate is also called magnesite plate or magnesium plate.
2. The production of magnesium oxide board consists of active high-purity magnesium oxide (MgO), high-quality magnesium chloride (MgCl) alkali resistant glass fiber cloth, extremely flexible plant fiber, incombustible and light perlite, chemically stable lithopone, polymer and high-performance modifier.
3. magnesium oxide board has the advantages of high temperature resistance, flame retardancy, sound absorption, shockproof, insect proof, anti-corrosion, non-toxic, tasteless and pollution-free, can be directly painted, directly plastered, and can be directly applied with air nails and ceramic tiles.
4. The surface of magnesium oxide board has good coloring property, high strength, bending resistance, toughness, nailing, sawing and gluing, and convenient decoration.
5. magnesium oxide board can also be combined with a variety of insulation materials to make composite insulation plates.
Light-burned magnesia powder is one of the main raw materials of magnesium oxide board, which is calcined from magnesite MgCO3 at '750% ~ 850~C. The calcination process of some manufacturers is relatively backward, especially the measures for homogenization of raw materials or ore after calcination, resulting in a large gap between the MgO content and the effective MgO content of the same batch of products, even the same bag of products. In order to unilaterally pursue production costs, some producers often use magnesia to replace light-burning powder to produce magnesia material products, which is impossible to produce high-quality magnesia fireproof boards. In order to ensure the qualification and stability of MgO raw materials and produce qualified fireproof boards, the raw materials of light-burning MgO are used, and the MgO content is 80%-85%, the active MgO content is ≮60±2%; the Ca0 content is less than 1.5%; The loss is 5%-9%; the fineness is ≮170 mesh.
1. Versatility: The unique smooth and rough surface of magnesium oxide board provides functional diversity for customers' use. Smooth surface can be pasted with wallpaper, aluminum-plastic board, veneer fireproof board, veneer, PVC, spray paint or latex paint, etc.; rough surface can be pasted with ceramic tile, marble, granite, ash and latex paint. The magnesium oxide board has an excellent affinity for the above-mentioned materials, and can be processed or used twice on site. It can be bent with a diameter of 30cm without loss of physical properties.
2. Durable and durable: the scientific formula completely solves the problem of moisture absorption and halogen return of magnesite, its strength increases with time, it can resist corrosion, acid and alkali resistance, the change of thermal expansion and cold shrinkage is small, and the dry shrinkage rate is less than or equal to 0.3%. The swelling rate is less than or equal to 0.6%, and it has the frost resistance of -40℃. After ten years of testing, the magnesium oxide board is durable, resistant to aging and has a long life.
