What is the density of the ceramic fiber module The insulation effect is the best

There is only one standard for the density of the ceramic fiber module in the world, which is 220kg m, but in practical application, the density of the ceramic fiber module is set at 200-240kg m according to the furnace type, temperature, combustion medium, temperature rise requirements of the heat treatment furnace, because the ceramic fiber module is processed by the ceramic fiber blanket of the double-roller wire throwing process with today's more advanced technology, and the fiber length of the ceramic fiber blanket produced is between 80-130 mm. Therefore, the maximum density of the ceramic fiber module is 240kg m, beyond this density, the fiber will break a lot, and the fracture rate is as high as 48%. Therefore, after the actual verification of tens of thousands of industrial furnaces at home and abroad, the optimal density of ceramic fiber module is 220kg m.

The density of the ceramic fiber module is generally 200-220, the earliest production of ceramic fiber module is generally made of ceramic fiber spray blanket, the fiber of the spray blanket is thin and short, and the expansion of the ceramic fiber module is relatively stable, and in recent years, because of the production cost, most of the ceramic fiber modules are made of silk throwing blanket, the relative tensile force is relatively large, according to the temperature of your own furnace body, the heating situation of the module and the combustion atmosphere in the skull, choose the density and thickness of the ceramic fiber module. It is recommended to do 200kg cubic meters just for the insulation layer. Huanao Refractory Insulation Materials Company has specific indicators and analysis design.

Ceramic fibers. Thermal insulation cotton generally refers to ceramic fiber blanket, which is made of ceramic fiber loose cotton through the needle loom for double-sided or single-sided needle punching, and then transported to the high-temperature chamber by roller for high-temperature shaping, followed by electronic thickness measurement, precise cutting and roll packaging, etc., to improve the thermal conductivity of the ceramic fiber blanket.

You can see**Detailed explanation:

As we all know, the thermal conductivity determines the thermal conductivity of the insulation material, and the lower the thermal conductivity, the lower the thermal conductivity. Jinan Huolong Thermal Ceramics Co., LtdDu Gong suggested that it is rational to choose the type of ceramic fiber blanket according to the temperature of use.

In order to simplify and speed up the construction of the kiln and improve the integrity of the furnace lining, the new refractory furnace lining products are introduced. The product is white and regular, and can be directly fixed on the anchor nail of the steel plate of the industrial kiln shell, which has a good fire-resistant and heat-insulating effect, improves the integrity of the kiln fire-resistant and heat-insulating orange socks, and promotes the progress of kiln masonry technology. Classification temperature 1050-1400.

The choice of ceramic fiber module density has become an undecided item for brick factory owners, and many ceramic fiber module companies are also constantly working on densityJinan Huolong Thermal Ceramics Co., LtdDu Gong reminds everyone here that if the tunnel kiln flat ceiling is made of ceramic fiber modules, it is recommended to choose the density of two hundred and two kilograms per cubic meter. If you use ceramic fiber folding blocks (large blocks) to do it, it is recommended to choose a density of two hundred kilograms per cubic meter.

Features::

Excellent chemical stability; Excellent thermal stability; Excellent elasticity, the ceramic fiber module is in a pre-loaded state, after the furnace lining masonry is completed, the expansion of the ceramic fiber module makes the furnace lining seamless, and can compensate for the shrinkage of the fiber furnace lining, so as to improve the thermal insulation performance of the fiber furnace lining, and the overall performance is good; Excellent thermal stability and thermal shock resistance; The ceramic fiber module is quick to install, and the anchors are located on the cold side of the wall lining, which reduces the requirement of anchor material.

Typical applications: Thermal insulation of furnace linings in the petrochemical industry; Lining insulation of furnaces in the metallurgical industry; Thermal insulation of furnace lining in ceramic, glass and other building materials industries; Thermal insulation of heat treatment furnaces in the heat treatment industry; Other industrial kiln linings.

With the advancement of the national energy conservation and emission reduction plan, the transformation of the brick-fired tunnel kiln is imminent, and the ceramic fiber module has been greatly praised for its excellent thermal insulation performance in the ceiling of the brick-fired tunnel kiln.

Ceramic fiber modules can be divided into the following types according to different molding methods:

Modules, including folding blocks, slicing blocks, pylo blocks, vacuum forming blocks. Due to the different manufacturing methods and crystal structure of polycrystalline mullite fibers, the fiber length is short and the flexibility is poor. It cannot be made into a large module, resulting in the inability of polycrystalline fibers to be applied on a large scale.

At present, polycrystalline fibers are mostly used in castables or refractory bricks, and the inner surface of the furnace wall and furnace roof is mounted, and the use of polycrystalline fiber patches can effectively reduce the temperature of the furnace wall and reduce the heat storage loss of the furnace wall.

At present, the module form used by domestic ceramic fiber manufacturers is mostly a folding block, and the structure uses a needle-punched blanket for folding, and the module is pre-pressed by mechanical equipment during molding. Due to the production method of folding blocks, the surface is uneven, which affects the effect of anti-erosion coating spraying. The slicing block is improved on this basis, and it is made in the same way as the folding block, except that the fiber blanket fold is cut off after molding to make the surface of the module flat.

At present, some domestic manufacturers can produce such modules. The Pyro block is a completely new module that uses a completely different molding method than the above two modules, and the molded module fibers are not directional, so the insulation effect is better than the first two modules. The fiber module density of the furnace roof should be 230 kg m3, and the fiber module density of the side wall should be 220 kg m3.
