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's the difference between high alumina refractory bricks and high alumina refractory bricks?
High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.
Q:The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
Lining 1 yuan to prevent direct damage to the Sindh kiln high temperature flame or air, to protect the kiln carcass; 2, to prevent harmful substances (CO, SO2) erosion of the kiln body; 3, to prevent corrosion, material flow on the kiln body; 4, reduce the kiln temperature, kiln body to prevent oxidation 5, has the function of corrosion; thermal insulation; 6, to improve the coating performance.
Q:What are the common thermal insulation materials for thermal conductivity?
Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
Q:What are the lining structures of lime rotary kilns and what are the requirements for refractories?
The physical and chemical properties of refractory materials used in rotary kiln are as follows: physical and chemical properties of refractory materials used in rotary kilnMaterial name: high temperature compressive strength (MPa), softening temperature (DEG C), thermal shock resistance (1100 DEG C, cold water), sub volume density (g/cm3)Magnesia spinel brick is greater than or equal to 50 is greater than or equal to 1700 = 12 = 2.95High alumina brick is greater than or equal to 75 = 1520 = 8 = 2.57High aluminum bricks more than 50 = 1700 = 12 = 1The clay brick is greater than or equal to 30 = 1400 = 12 = 2.30
Q:The difference between light high alumina brick and heavy aluminum brick
Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
Q:Does the chimney have high acid resistance?
The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.
Q:What should be used as binder for making high alumina bricks?
Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.
Q:What are the specifications for bricks?
Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
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.
