Product Description

  Cenosphere, sometimes called microsphere, is a light weight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas., typically produced as a byproduct of coalcombustion at thermal power plants. The color varies from gray to almost white and their density is about 0.6–0.9 g/cm³, all these property give it a widely application for insulation,refractory,oil drilling,coating,construction use.

Q:What are the models of refractory cables?
The models of refractory cables: NH-KVV22 copper core flame-retardant PVC insulated and fire retardant control cables with steel belt sheath NH-KVVRP copper core flame-retardant PVC insulated and fire retardant shielding control cables with steel braiding sheath NH-KVVP2 copper core flame-retardant PVC insulated and fire retardant shielding control cables with sheath and steel belt wrapping NH-KVVRP2 copper core flame-retardant PVC insulated and fire retardant shielding soft control cables with sheath and steel belt wrapping NH-KFF copper core fluorine plastic insulated and fire retardant control cables with sheath NH -KFFR copper core fluorine plastic insulated and fire retardant soft control cables with sheath NH -KFFP copper core fluorine plastic insulated and fire retardant shielding control cables with sheath and copper wire braiding
Q:The effect of a high content of water in liquid resin exerted on refractory material?
For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
Q:What are the best refractory materials in 2,400 Celsius degree?
You can try zircon sand which has a melting point of 2430.
Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
Now cone crusher is generally used.
Q:What is streaming fireproof material?
Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.
Q:How many levels are there in the classification of PP fireproof materials?
PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
Q:What are the material requirements of class A fire resistant door ?
What are the material requirements of class A fire resistant door ?
Q:Who can tell me what is neutral refractory?
Neutral refractories refer to the refractory materials which will not react greatly with both acidic and basic slag at high tempreratures. Such as carbon refractories and chromite refractories. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc.
Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
Adding flame retardant or fire retardant materials can be fireproofing, which commonly referred to as the external walls of fire retardant coating or fire retardant coating. Principle: Fireproof paint itself is flame-retardant or non-combustible, so that the protected base material can not directly contact with the air in order to the ignition delay and reducing the burning speed; except that, it also has a lower thermal conductivity, which can delay the transfer of flame temperature to the protected base material; fireproof paint thermal can decompose non-combustible inert gas by heating to dilute the thermal decomposition of combustible gas in protected object, making it difficult to burn or slow down the speed of burning.
