Q3:What's the MOQ of trial order?

A:No limit,We can offer the best suggestions and solutions according to your condition.

Q4:Which payment terms can you accept?

A:T/T,L/C are available for us.

Q5:After an order is confirmed, when to deliver?

A:15-25days after deposit.

Q6:Is your company accept customization?

A:We have own factory and excellent technical team,and we accept OEM service.

Q7:How about your company's certification?

A:ISO9001 and Test Report,also we could apply other necessary certification.

Q8:How to slove the quality problems?

A:If the products are not confirmed to customer samples or have quality problems,our compay will be responsible to make compensation for it.

Q9:Can you offers samples?

A:Of coures,samples are free but freight paid by the buyers.

Q10:What is the service life of your bricks?

A:The service life of different bricks is unlike.It also depends on your using condition and method.

Q: What are the specific raw materials for plastic pallets?
There are two kinds of raw materials for plastic pallets: one is polypropylene (PP) and the other is polyethylene (HDPE).Plastic pallets for logistics storage: pp+pe material, recycled material 10%;Plastic trays for food trays: food grade PP, PE, pc;Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.
Q: Aluminum content 38, silicon content 55 What refractory bricks?
Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite
Q: Which is better, the soft core or the hard core?
The use of each of the single core copper wire with low line, 1.5 square with cap line home, socket 2.5 square, air conditioning to walk alone line 4 square can, when the terminal box into a socket with leakage protection switch, prevent overload and short circuit.
Q: What are the requirements for refractory materials in heat treatment furnace?
Refractoriness is the property of a refractory against high temperature, which means the temperature at which a refractory is softened to some extent after heating, but not its melting point. According to the degree of refractory, refractory materials can be divided into: General refractories, refractory degree is 1580 to 1770 DEG C; advanced refractories, refractory degree is 1770 to 2000 DEG C; special refractory material, refractory degree is greater than 2000 DEG C.
Q: How to reduce the harm caused by two times mullite in high alumina refractory material
Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
Q: Is glass wool inorganic thermal insulation material?
The characteristics of glass wool, glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
Q: Which thermal shock stability of clay brick and high alumina brick is good?
The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.Thermal shock stability is much better than clay brick.
Q: What is the high temperature limit of refractory bricks and refractory soil?
Refractory bricks are stone powder and clay paste. They are fired in a kiln of 1300 degrees. The upper limit is 1500 degrees above normal pressureRefractory bricks - refractory materials of a specified shape and size.
Q: The difference between clay bricks and clay bricks
Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.
