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:What are the PCBs
1) Flame Retardant Copper Foil Epoxy E Glass Fiber Cloth Laminate and Its Adhesive Sheet Material. IPC4101 detailed specification number 21; Tg ≥ 100 ℃; 2) Flame Retardant Copper Foil Modified or Unmodified Epoxy E Fiberglass Laminated Laminate and Bonding Sheet Material. IPC4101 detailed specification number 24; Tg 150 ° C to 200 ° C; 3) Flame Retardant Copper Foil Epoxy / PPO Glass Cloth Laminate and Its Adhesive Sheet Material. IPC4101 detailed specification number 25; Tg 150 ° C to 200 ° C; 4) flame retardant copper clad modified or unmodified epoxy glass cloth laminate and its adhesive sheet material. IPC4101 detailed specification number 26; Tg 170 ℃ ~ 220 ℃; 5) Flame Retardant Copper Foil Epoxy E Glass Cloth Laminate (for Catalytic Addition). IPC4101 detailed specification number 82; Tg N / A;
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:Density board, multi-layer board Why should the number of units as a unit, what standard Mody, a variety of plate is a number of sheets?
In order to facilitate the transport and storage, these two kinds of plates will be packaged, a packaging is one, there is no standard, the number of thick less, the number of thin more, for example, we used to play 18% of 40, 50 or 75 sheets one.
Q:Which glasses glasses and metal glasses is better?
In fact, nothing is good and bad, the plate is partial fashion a little, the metal may be durable some of the price of some of the metal, the plate is generally very cheap, if the age is not recommended to buy plate, I am not professional, before also In the up to buy online, asked the customer service, it is best to go to the glasses site asked the professional staff
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:What is FR4 sheet
FR-4 is a glass fiber epoxy resin CCL, a circuit board in the substrate, in fact, you should have seen, such as the kind of small game machine to open, inside the green board is FR-4 to do circuit board.
Q:Pb board is what material
PB: Polybutene, polybutene, a high molecular weight polymer.
Q:What are the plates?
Usually made of standard size flat rectangular building material board, as a wall, ceiling or floor components. Also refers to the forging, rolling or casting made of metal plate. Divided into thin plate, medium plate, thick plate, special thick plate, usually made of standard size flat rectangular building material board. According to the material classification can be divided into solid wood, wood-based panels two categories; according to the classification can be divided into solid plate, plywood, fiberboard, decorative panels, fire board, particleboard and so on.
Q:How much does the ring do the ring?
Do ten ring certification is mainly to see if you are doing a type of ten rings or two rings, if you do here for the purpose of ten rounds of tender, it is recommended that you can do a type of ring certification. You need to do the EIA, but also to prepare the early data. I was in OKorder million Germany to do the ten ring certification, then in order to bid, so do anxious, a month to get the card
Q:PCB board which expensive?
South Asia and the benefits of the best technology, but South Asia has its own upstream industry support lower cost, cheaper, raw technology and quality control better.
