magnesite
It is not suitable for building materials because its content is less then 60%, Light burned magnesium oxide powder price is 2 times the price of magnesite what's more it has much impurities .Fireproof performance is worse than light calcined magnesite .
Light burned magnesium oxide powder
It is suitable for building materials and fireproof materials because its content is more then 85%, Light burned magnesium oxide powder price is 2 times the price of magnesite what's more no impurities .Its fireproof performance is betterr than magnesite .
More details:
MGO fireproof sheet is a kind of environmental-friendly fireproof board widely used in construction and decoration. It's made from magnesium oxide, magnesium chloride, fiberglass mesh, sawdust, perlite etc. We use, highly-purified active MGO as the main fireproof material of board, high-quality MgCl2 as the main cementing material to solidify other materials, alkali-resistance fiberglass mesh to ensure the high strength of board, soft sawdust and light non-combustible perlite as filling materials.
MGO fireproof sheet enjoys strong points in more fields compared with the plasterboard and the traditional partition board, either in the decoration for modern construction or the fire resistent division for the industrial workshops
Features of the products :
1. Strong fireproofing capability: All the specifications of this product has reached the requirement of GB8624 fireproof level A and JC688-2006.
2. Good shockproof capability: This product is designed with many layers of high-strength fiber webs, which can effectively absorb part of the energy from the earthquake to avoid the instantaneous collapse of the isolation wall.
3. Smooth and scratchproof face: Advanced European and American production technology and recipes is introduced for this product, thus the turned-out board material is of smooth face and high hardness, collision and impacting will not result in depressions and scratches.
4. Good safety performance: This product is 100% free of asbestos and radiation, nor will it create the organic substance harmful to human bodies.
5. Superior performance in sound insulation and heat insulation: When used as the partition, this product can be filled inside to absorb sound, whose performance in sound insulation is better than the single brick wall meanwhile the cold and green house effect is raised, which saves energy and increases the economic benefit.
- Q: How to do the corn stalks
- Process Technology Line: 1. Straw density plate: Air dry straw → impurity removal → cut off → wind selection (blown out of the heart) → cans → high pressure steam → spray → fine → spray → drying → pavement → preload → hot pressing → edge → cutting → packaging → finished product 2. Straw crushed plate (particleboard) Drying Straw → Cutting → Wind Selection → Recovering → Drying → Screening → (Surface Layer, Dust, Core Material) → Mixing → Pavement → Preloading → Hot Press → Edge → Cutting → Inspection → Packaging 3. Straw composite board Straw → Cutting → Steam Blasting → Mixing → Paving → Wood Veneer → Glue → Preloading, Hot Press → Side → Varnish → Sanding → Finished 4. New wall materials: Corn stover high grain straw → election → leaves → cut → pavement → irrigation → do the surface layer → veneer → sanding → finished In addition to the above processing, the straw can also be used for pulp making after steam blasting, which is about a third less expensive than traditional pulping methods and only one third of the traditional method. It is helpful to solve the problem of pulp gap caused by the forced cessation of small papermaking by the state. Fourth, the main technical key and expected to achieve the technical and economic indicators: 1. Main technical key: ① developed as low as possible, environmentally friendly, waterproof superior, infiltration of a good name of the glue. ② design and improvement of grading pavement. ③ steam blasting equipment selection and the determination of the main process parameters. ④ hot pressing and cold pressing process parameters adjustment. 2. Expected technical and economic indicators: ① adhesive; solid content: 60% -65% ??????????Free formaldehyde content: 0.2% or less ??????????Viscosity: coated with 4 cups: 30 ℃ 10-20 seconds (fiberboard) ?????????????????????????????????50-65 seconds (particle board)
- Q: Decoration used plate, and asked the price of three thousand square plate how ah
- There are some quality of the plate although meet the requirements, but they are more complex processing technology, such as your paint to waste some of the amount, or not strong and so on.
- Q: What is the board made of the board?
- Wo Hong board it, I strongly recommend the use of Wo Hong board The specific can be their own search in , Wo Hong board is indeed no formaldehyde
- Q: Plate and line joints at the crack causes, with morning sun water paint can improve it
- I can use the morning sun water-based wood paint, like a wooden furniture clothes, not only cleverly cover up the wood surface of the insects, knots, color and other defects, but also to highlight the beautiful texture of wood, while Play the role of protection of wood. Recommend you try, very safe
- Q: Guangzhou red cotton plate and ordinary moisture board What is the difference

- Q: PCB plate manufacturers are famous what
- Sunrise, Matsushita, Arlon, Nelco, Rogers, Tanconic, polyflon, etc.
- Q: PCB board material how to identify
- PCB board material identification, can be carried out from the following four aspects: (1) dimensional stability In addition to pay attention to X, Y axis (fiber direction and horizontal direction), but also pay attention to the Z axis (plate thickness direction), due to thermal expansion and contraction and heating reduction factors easily lead to silver plastic conductor fracture. (2) electrical and water absorption FR-1 is better than FR-1 and XPC in terms of dimensional safety, electrical and water absorption, so that the insulation of the insulator in the absorbent state is reduced, so that the metal is moved under the potential difference. Production of silver through-hole printed circuit board, to use special FR-1 and XPC paper substrate. (3) ductility Copper plating through the copper hole is a continuous crystal, there is a very good ductility, not like silver, carbon ink in the thermal expansion and contraction, easy to interface separation and reduce the conductivity. (4) migration Silver and copper are metal materials, easy to oxidize and restore the phenomenon caused by rust and migration phenomenon, due to the difference in potential, silver than copper in the potential difference between the trend of prone to silver migration (Silver Migration). Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit.
- Q: How much is a cafe?
- White wax and red oak from the North American material of ash and red oak, such as according to the domestic material, wax for the ash, oak for the oak. These two kinds of wood is a good wood, such as produced for North America, The price is also closer to the two, such as white oak is more expensive. These two kinds of wood have long been used in furniture production, especially in American furniture. American furniture, the most common wood is in turn: white oak, Red rubber, white wax, cherry, maple, black walnut etc ... so the specific choice of which kind of wood, need to see your personal preferences.But if you can not determine whether the wood produced in North America, I suggest you use red rubber. At present, a large number of domestic use of Russian Fraxinus instead of North American white wax, low price. Color yellowish, but can be bleached. Furniture material marked wax. The red oak of the argument generally refers to the North American material, Russia's oak white and yellow, production Out of the furniture generally oak, rather than specific to white rubber or red oak
- Q: What is cold rolled plate ah? Cold rolled plate is a plate of no
- Cold rolled coil is hot rolled coil as raw material, at room temperature in the recrystallization temperature of the following rolling, including the board and volume, many domestic steel mills such as Baosteel, China Iron and Steel, Anshan Iron and Steel can produce.
