Q:How to choose thermal insulation materials for flood heating?
By controlling the foaming ratio, nucleating agent size, moudle pressure, temperature of screw, vacuum foaming technology, extruded sheet of different density can be made. The density of commonly used plastic extruded board is 25-50 kg per cubic meter. Plate density is the main factor affecting the cost of the extruded plate. The higher the plate density, the higher the cost price. Plate density is the main factor affecting the cost of the extruded plate. The lower the density of extruded board, the worse quality performance. Plate density of common plastic extruded is between 30 to 38 kilograms per cubic meter. The density of plastic extruded plate of exterior wall is between 30-35, if the density is too low, then the plate will not be strong enough, if high, flexibility of plastic extruded board will be inadequent, unable to bear the stress brought by housing settlement deformation, resulting in cracks in the wall. With the extrusion plate for floor heating should be in 36 kilograms per cubic meter. If it is too low, ground subsidence will occur due to the low strength, resulting in the ground crack. If density is too high, the thermal conductivity coefficient will increases, impacting energy saving. High density extruded plate is generally used for occasions having special requirements for compressive. Parking lot roof should use extruded plate above X350, whose density is 40 kg per cubic meter. The aircraft need to use the Ping extruded board above X500, density in 45 kilograms per cubic meters. High speed railway subgrade need to use extruded plastic board above 700KPA,
Q:What type of firebrick does TZ-3 represent?
Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).
Q:What material is refractory material?
alumina refractory concrete, silica brick clay brick, metal ceramic, high temperature machine coating fiber reinforced ceramics, diatomite product, asbestos products, insulation board refractory. The definition of refractory can be searched in the website.
Q:Who knows how many fire heat preservation material are there?
They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
Q:How is the performance of refractory materials?
It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
Q:Is refractory material harmful to human body?
Part is harmful to human body, mainly refractory raw material, silica powder inhalation can cause lung tuberculosis, siliceous fiber on the human body does have great harm, in fact, like other inorganic fiber in the inhalation of the trachea or lung after the same harm to human
Q:I wanna ask what are the acidic refractories?
Usually, acidic refractory refers to a kind of refractory which contains a amount of silicon dioxide. There are the following: (1) silica brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. The main features of the acidic refractories is resistant to the erosion of acidic substances (acidic residue) in high temperature, but is easy to react with alkaline material (basic slag). zirconite fireproofing material and silicon carbide as the special acidic refractories refractories are also in this category.
Q:What is the difference in the nature between the refractory material and thermal insulation material
thermal insulation material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
Q:Is there a worker in (Jigang refractory plant)?
Ha ha, base should be rest, you won't give you money, Hugh or those money, endlessly is your dedication. Should be double cease, ah, how do you say four days?. In theory, it's five days off now, and the three day of that is from the chairman to every employee.
Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
