Product Description:

Refractory clays insulating firebricks/good thermal insulation bricks:are made of Mullite material in good purity.In order to meet the thermal and physical requirements,we produce BJM insulating firebricks into several grades through the addtion of alumina.And we also add some material (which will burns out) to get the pole structure which is helpful for the heat thermal. This kind product used for oven/ furnace and some equipments working in high temperature by back-up insulation behind other refractories.The production of these goods are strictly in size and quality.


Advantages of Refractory clays insualting firebricks/good thermal insulation bricks:

 

• Made of high pure material,light weight

• Color pure white

• Good thermal conductivity

• Great thermal shock resistance

• very good volume stability at high temperature

Q:What are the specifications of high strength diatomite insulating bricks?
Exterior wall insulation decorative board insulation performance is very good, and the processing method, anchor node and patent products cold bridge design reduces the energy loss, therefore, especially in the area of bad weather such as the northeast, northwest and other places, energy-saving insulation requirements are very high, the traditional thermal insulation construction has brought great difficulty to the construction.
Q:The difference between ordinary and diatomite brick refractory brick?
To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
Q:What bricks are thermal insulation bricks?
Thermal insulation brick is a new type of building material synthesized with macromolecule material. Grey, hollowed out bricks are basically.
Q:What is the maximum temperature range of high temperature resistant insulation materials?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q:What's the difference between refractory bricks and insulating bricks?
As far as we are concerned about the characteristics of refractory bricks and thermal insulation bricks, refractory bricks are sure to be aimed at fire resistance, while insulating bricks are more focused on thermal insulation. And more specifically, let's take a look at the following parameters.
Q:What material is good for indoor thermal insulation?
Own home, if the south, hot summer and cold winter zone, with inorganic insulation mortar or polystyrene particles insulation mortar, the effect is very good;
Q:Are there any differences between insulating bricks and refractory bricks
The degree of refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. density insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
From the structure principle, hydropower shaft with solid brick, is to consider the safety performance of the structure.
Q:What is the function of insulating bricks? Where can I use it?
Low thermal conductivity, high strength, strong durability, simple construction, light weight, easy loading and unloading, economic, green, environmental protection, sound insulation, fire protection and so on.Thermal insulation brick is a new type of energy-saving building insulation technology with inorganic composite material as the main material. It is an ideal technology to replace the traditional wall insulation. The insulation brick integrates the excellent heat preservation effect into the wall while building the wall.
Q:What materials are used for roof insulation
There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
