Product Description:

Product Discription:

OKorder is offering high quality Heat Insulating Vermiculite Products at great prices with worldwide shipping. Our supplier is a world-class manufacturer of expanded vermiculite, created using raw vermiculite which is heated to 900-1000 degrees. After heating, the vermiculite’s volume increases by 6-15 times, even as much as 30 times, resulting in an expanded vermiculite with little heat conductivity and excellent thermal insulation. We have supplied Heat Insulating products to European, North American and Asian markets. 

Our Heat Insulating Vermiculite Products are ideal for:

  • Gasket seals

  • Fireproofing Insulation in steelworks and foundries

  • Packing material

  • Animal feedstuffs

  • Friction linings

  • Refractory products

  • Processed vermiculite

  • Bitumen coated vermiculite plates

  • Construction coatings

  • Lightweight concretes

  • Loose fill insulation

  • Vermiculite plasters

  • Fireproof board

 

Not only are OKorder's Heat Insulating Vermiculite Products of the highest quality and reliability, we are able to quickly ship orders within 20 days of receiving a deposit or original L/C.

Q:How can refractory material of the electric furnace be used for longer.
Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life
Q:What are the materials of white firebricks?
White refractory materials are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
Q:How many hours of the fire endurance time of the rock wool laminboard?
Limit is usually two hours. Pay attention to it please.
Q:What material is used for making refractory stone bowl?
Good refractory stone pot is carved from high-quality natural refractory stone in a professional way. But many are also made of synthetic materials, the price is lower, too.
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:how to divided the external wall thermal insulation materials fire rating
The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:Does anyone know fire-proof material of fireproof wooden door?
Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm .
Q:What are the specifications of fireclay bricks?
Dimensions of refractory bricks : 230 * 115 * 65mm
Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
The material is very troublesome, it might crack horrendously if not baked well and all of them may be scraps after being took out from the furnace. Magnesia hydration is inevitable during the baking process. As volume expansibility of magnesite reaches 200%, so it is easy to crack. The key to bake is to quickly rule out the water vapor in furnace, especially within 150 degrees Celsius. After quickly ruling out the water vapor in furnace to avoid excessive reaction with magnesia of 150 degrees, it can be operated in accordance with convention. In addition, you should pay attention to the heat sources, for which i recommend electrical and coke to avoid generating a lot of water vapor during the natural gas combustion process which will worsen the situation.
Q:What's the refractory material?
Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
