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:Why does the water drop first and then rise when the boiler fires?
Often in the operation of the boiler, the steam water mixture to the drum after intense evaporation of a large number of bubbles in the water side, the water volume expansion. By actual water level drum water level indicator is higher than the water level
Q:What is mullite insulation brick?
Main features of mullite insulating bricks:1., green environmental protection, non-toxic, non corrosive, safe to use.2. 、 good adaptability with cement.3., light insulation brick with foam mechanism bubble, can get foam uniform bubble diameter.4. excellent foaming performance, foaming multiples of more than thirty times.
Q:What is a heat insulating brick?
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.
Q:What is a JQK composite lightweight thermal insulation brick?
Its characteristic is waterproof and heat insulation, thermal insulation performance, strong decoration, waterproof effect is good, and good weathering resistance, long service life, the whole system of simple construction, low cost, is a new type of inverted waterproof and insulation structure of the current system state key application.
Q:What are the improvements and improvements during the trial production of insulating bricks?
Per square metre weighs only about 1.4 kilograms, reduce the burden of building.Simple production: completely break through the traditional process, greatly shorten the construction cycle.
Q:What are the bubble bricks?
The steam free aerated block has the advantages of wide raw material sources, high waste rate and low cost. With fly ash, slag, sand, sand, soil containing low amount of powder and tailings as the main raw materials (with one can), local materials, low cost, high profit.
Q:Advantages and disadvantages of external formwork and self thermal insulation block
Self insulation block first meet the requirements of national energy conservation, the outer template also meets the requirements, but the process is more complex, higher cost,Insulation block although the price is high, but does not appear to burst mode, collapse, internal cracking and other problems, while the internal insulation block can control the cracking problem, the difficulty of construction on the ratio of template to technology, can refer to and block construction!
Q:What are the specifications of high strength diatomite insulating bricks?
Exterior wall decorative plate is made from polystyrene resin as raw material and other raw materials and polymer content, by heating mixed with catalyst, rigid foam board and plastic extrusion molding and manufacturing, has moisture-proof, waterproof performance, can reduce the thickness of building envelope, thereby increasing the use of indoor space.
Q:The insulation layer destroyed after use of cement paste and tiling
Attach tiles directly to the insulating layer. But one requirement is to check the insulation process in the balcony of your house. Usually wall - insulation layer - galvanized wire mesh - cement mortar, scraping - paint. If the lack of process fill such as galvanized mesh, remove paint, and tiling. You can use high mark cement or direct adhesive.
Q:Coke burns in a closed house. Will anyone suffocate in it?
Not suffocating in the short term, will suffocate for a long time.
