OCM Cement Board

-Lightweight and durable backboard

OCM cement board is a board made of 90% Portland cement and sand.

No loose abrasive aggregates or fillers

Maximum bending strength.

The size of the board is usually 4 feet by 8 feet, and the thickness is between 3 mm and 30 mm.

The main purpose of cement board is to be used as a backing for tiles, and it is better than paper plaster due to its water resistance.

It is important to have a backing that will not mold, mold, or disintegrate after prolonged exposure to moisture.

OCM cement board is used wherever ceramic tiles are installed to increase the strength of the supporting structure.

The OCM cement board uses a unique cement formula and structure, which is an ideal combination of strength, uniform composition and performance, which other support boards cannot provide.

What is sanding board?

    Sanding plate has single sand and double sand two categories.

    Sanded mgo board surface treatments can be varied,such as sanding and polishing,which made board smoother and flatter,the thickness is more accurate which is suitable for lamination with PVC film,HPL and paper.

    The application is lamination with PVC film,HPL sheet and paper.Flooring core for composite flooring replace of PVC and SPC.

    The features is one side polish,one side sanding treatment or two sides sanding treatment.UV or waterproof painting coated also available.

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?

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.

What are the main raw materials of magnesium oxide board?

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.

What is the reason for the popularity of magnesium oxide board in the market?

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.

Magnesium oxide board is widely used in partition walls and ceilings of various interior decorations such as hotels, shopping malls, restaurants, night clubs, banks, hospitals, supermarkets, office buildings and domestic residences. It is completely suitable for thermal insulation structures, sound insulation walls, movable partition walls, super fire protection, fire door inner plywood, equipment box outer packaging and other areas.

What are the product features of magnesium oxide board?

The magnesium oxide board is made of non-combustible materials such as magnesium oxychloride, magnesium oxide, alkali-resistant glass fiber cloth, wood chips, etc., and is processed by a full set of automatic assembly line equipment with a special production process. It has many advantages such as environmental protection, odorless, non-toxic, non-flammable, smoke-free, high-strength and light-weight, sound insulation and heat preservation, waterproof and fireproof, non-freezing and non-corrosion, minimal expansion and shrinkage rate, no cracking, no deformation, etc.

What are the characteristics of raw materials of magnesium oxide board?

Magnesium oxide board is a ternary system of magnesium oxide (MgO), magnesium chloride (MgCl2), and water (H2O), which is prepared and made with modifiers, and has stable magnesium cementitious properties. It is a new type of non-combustible decorative material compounded by medium-alkali fiberglass mesh as reinforcing material and lightweight material as filler.

  Magnesium oxide board has the characteristics of light weight, high strength, small shrinkage, easy construction, etc., especially its unique new waterproof, fireproof, corrosion-resistant, plasticity is better than the wooden multi-layer plywood, paper gypsum and other decorative materials that flood the market. For partition walls and suspended ceilings.

What is the main material of magnesium oxide board?

MgCl2 is one of the two main raw materials of magnesium oxide board. Its quality requirements mainly include two aspects. One is the effective content of MgCl2. It is clearly pointed out in the JC/r449-2000 standard that MgCl2 ≥ 43%, calcium ion Ca content ≤ 0 .7%; on the other hand, alkali metal chloride (calculated as Cl-) ≤ 1.2%, because the content of Ca and Cl- will directly affect the stability and frosting of the product. As the magnesium oxide board is rich in Cl - it is corrosive to metal and cannot be reinforced with metal for a long time. In addition to taking effective measures to prevent the existence of residual MgCl2, MgSO4·H2O or MgSO4·7H2O can also be used to replace part of MgCl2·6H2O, and silica fume can be used to replace part of light burning. MgO powder, its performance is no different from the performance of magnesium material, but the material cost is relatively high, making it difficult to popularize in a large area.
