Q:What are the specifications for bricks?

In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

Q:What is the density of a super high alumina brick and what is the price?

Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan

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:How much is one ton / ton of high alumina refractory brick?

The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

Q:What are the categories of bricks?

Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.

Q:What is fireproof concrete?

According to the different properties of fire resisting and heat resisting concrete, they can be divided into silicate, aluminate, phosphate, sulfate, chloride, sol and organic substance, fireproof and heat-resisting concrete, etc.. The following are mainly used silicate, aluminate, phosphate, sulfate fire, heat-resistant concrete.

Q:How to reduce the harm caused by two times mullite in high alumina refractory material

Prolong the sintering time and adjust the aluminum content of the high alumina brick.

Q:How to make refractory bricks and boiler wall adhesion more firm?

If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.

Q:Which is better, the soft core or the hard core?

When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.

Q:What is the heat preservation material used in a laboratory furnace?

Asbestos, high alumina brick, or carbonized silicon are often used.Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
