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:What are the fireproof materials currently used in construction and decoration?
Building materials, fireproof materials, non-combustible materials A-level: cement, stone, steel, paint,
Q:Building ceiling material fire rating
See "Building interior decoration fire protection design specifications
Q:Ventilation duct fan outsourcing fireproof material specifically what
8.5.6 Ventilation, air conditioning system piping, etc., should be made of non-burning materials, but contact with corrosive media duct and flexible joints, can be made of refractory materials. 8.5.7 Insulation materials, silencers and adhesives for pipes and equipment shall be non-combustible materials or refractory materials. Through the firewall and deformation of the duct on both sides of the 2.00m should be used within the scope of non-combustion materials and binders. 8.5.8 When the electric heater is installed in the duct, the fan shall be interlocked with the electric heater. Electric heater before and after the 800mm within the duct and through the fire source and other places with easy fire parts of the tube helium bite of the Guobao every double Fu Jing Road, must use non-combustible insulation materials
Q:What is the raw material for producing fire retardant coatings?
Sodium silicate, high school, is the reaction of silica and sodium hydroxide
Q:Fire materials are generally what kind of ah, generally what indicators to determine its performance is good or bad?
You said the fireproof material refers to that piece of fireproof material? Is there any other request? For example, you said that the building fireproof material, it is generally frozen in the top of the world, there are rock wool, perlite, magnesite cement, cement, vacuum foil, etc., their performance to From the integrated point of view: fire rating, the use of temperature, fire time, waterproof, bending, wind pressure and so on.
Q:Is plastic as a fireproof material?
No, generally with pvc steel
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:How to brush fire paint
The surface clean, spray and brush can be
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?
Now the external wall insulation materials are required to reach A level, see "Gong [2017] 65"
Q:Fire protection requirements for indoor ceiling materials
In the building interior design fire, the common parts of the common technical requirements. 1. Ceiling (ceiling) In all the interior decoration of the fire design, the ceiling fire design in the most important position. This is because the fire is burning up the fire, the ceiling first and directly accept the fire test; the same time, there is a direct impact on the evacuation, will directly constitute a threat to the safety of evacuated personnel. Therefore, in the interior ceiling decoration design, should give full consideration to its fire problem. "Fire protection within the building design fire code" on the different civil buildings of indoor ceiling material fire performance has a detailed requirement. 1) single-layer, multi-storey civil building ceiling materials, generally should be non-combustible materials. The following buildings can be used in the construction of flame-retardant materials: ① construction area ≤ m2 of the station, the terminal waiting (boat) room, restaurants, shopping malls, etc .; 粻 open outline satin and other persuasion stitch ② each floor area < 1000m2 or the total area of ​​<3000m2 shopping malls business hall; ③ no central air-conditioning system hotels, hotels, office buildings and complex buildings; 2) high-rise residential building ceiling materials in addition to two types of high-rise civil buildings can be used to build the ceiling of flame retardant materials, the other should be used non-flammable materials. 3) underground ceiling of civil buildings should be used non-flammable materials.
