Product Description:

Vokes® NPP (Nanoporous insulation panels)


Characteristics 

Vokes® NPP is an evacuated micro porous thermal

insulating panel with excellent insulating properties.

Vokes® NPP 

The core material of

Vokes® NPP is fumed Silica board and noncombustible.

It is sealed into a high gas barrier film under vacuum.

Vokes® NPP

Application 

Vokes® NPP is specially developed for insulation

applications where not much space is available but a

high thermal resistance is necessary. Mainly used in

high-temperature insulationMainly used in hightemperature

insulation.

Vokes® NPP 


Vokes® NPP is a successful insulation element in the following areas:

• Industrial equipment insulation 

• High temperature boiler insulation 

• Thermal packaging (Medicine transport boxes, etc.)

• Appliance (Water boiler, etc.)

• Automotive (train, ship, air plains, etc.)

Advantage 

• Insulation : Long-term application temperature reached -120℃-1200℃. Insulation at normal

temperature for 3-5 times the performance of traditional materials. Stable thermal conductivity at high

temperatures, Temperature at 300 ℃ insulation performance is 4-8 times that of traditional materials.

• Drastically reduced insulation thickness 

• Thermal resistance :Particles constituting unit having a three-dimensional network structure,

will form many nanoporosity avoid sintering deformation.

• All purpose VIP with a long service life 

•Corrosion resistant :Products made of an inorganic material, no soluble chloride ions, No

corrosion on equipment, pipe grassroots.

• Soundproofing/Seismic Performance :Acoustic noise reduction, buffer shock.

• Waterproof :Product nanoparticles themselves with super hydrophobic properties.

Q:Guiqiu big god, online and other urgent! Will hydration of calcium silicate heat dehydrate to change calcium silicate?
(OH) · 4H2O can be seen from the water molecules, if the high temperature heating is likely to be decomposed into tricalcium silicate (3CaO · SiO2). ), Dibasic silicate (2CaO · SiO2), silica (SiO2) and water. The reaction equation is as follows: Ca5Si6O16 (OH) 4H2O → 3CaO SiO2 + 2CaO SiO2 + 4SiO2 + 4H2O
Q:Fire-resistant coatings are generally water-based or oily
Common fire-resistant coatings on the market are also water-soluble (oily). Fire retardant coating from the dispersion medium can be divided into: water and solvent-based two. Water-based fire retardant coating: water as a dispersion medium, the emulsion for the film-forming material, in a variety of flame retardants, filler composition of water-based fire retardant coating. Solvent (oil) fire retardant coating: organic solvent for the thinner, resin for the film-forming material, in a variety of flame retardants, fill the composition of solvent-based fire retardant coating. The difference between the two: water-based fire retardant paint green, environmentally friendly fire-resistant coating, is the national and industry recommended species. Solvent-based fire retardant coating because of the organic film in the process of drying, benzene, xylene and other needs to be volatile, so people and the environment have a certain impact, but in a certain environment, solvent-based fire retardant coating fire resistance, water resistance Chemical resistance is water-based fire retardant coating can not reach. With the continuous progress of technology, the future may be completely eliminated solvent-based fire retardant coating.
Q:Why do the bathroom cabinet with fire board material to do, easy to fire in the bathroom do
When the paint is in the paint, the paint is versatile. Both helium faint silhouette Oh child care can fire and waterproof, but in the time of the call are used to call the fire board, so there will be bathroom with fire board. It's mostly used here for waterproofing. ,,,,, hope adoption, ,,,,,
Q:Height greater than 60m residential building construction, when the use of B1-class insulation material, every few layers to set the level of fire isolation belt?
Drawings must have a description of ah, generally three layers
Q:What is A grade fireproof material?
A grade fireproof material refers to non-combustible material, is a kind of fireproof material. In China, building materials are divided into A, B1, B2, B3 four kinds of materials, respectively, said nonflammable, flame retardant, flammable and flammable, commonly used building fireproof material is A, B1, B2 three.
Q:What is the thickness of the thin fire retardant paint brushing each time?
Thin-type fire retardant coatings on the market for water-based paint, do not rule out the possibility of oil paint. Generally there are two kinds of spraying or brushing. Spraying thickness is generally between 05-1mm. According to the different characteristics of the coating to determine the construction process.
Q:Will the fire paint in general can buy it? Guiqiu.
Looking for me on the line, good quality, but also cheap
Q:I want to get a website about fireproof material.
However, first of all you have to have a good domain name, or bad promotion
Q:What kind of material can both fire and heat can float on the surface?
Urea formaldehyde. It is a thermosetting plastic that probably meets your requirements. General hardware shop also have to sell it!
Q:What is a level of fire. Secondary fire, three fire (steel)
