Q:what should be paid sttention when buying the refractory?
solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4: 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
Q:Why should graphitic refractory materials be used now that graphite can burn?
Materials for refractory must have the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point : 2800℃; 3, low price. Graphite has all three characteristics and properties, especially melting point and stability.
Q:Who knows the roofing fireproofing and waterproof material?
Many waterproof materials are suitable for civil engineering, and almost used in the roof waterproof layer, such as: Paint categories: 911 two-component polyurethane waterproof coating single component polyurethane waterproof coating polymer cement-based waterproof coating JS composite waterproof coating and so on. . Coil categories: single-sided waterproof roll double-sided self-adhesive waterproof roll modified asphalt waterproof roll (SBS, APP) polypropylene, polyester, polymer waterproof roll, PVC waterproof roll, EPDM waterproof roll
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Adding coarse aggregate is to assure its good combination with fine aggregate. This is just the experience. You don't have to ask.
Q:What are the applications of refractory busway?
Fire-resisting busway can be applied to power transmission and distribution systems with rated voltage below 690V, rated current is 250-5000A and frequency is 50-60Hz. After years of testing and industrial electrical operation, its electrical resistance, fire resistance, metal structural property have reached the advanced level in China.
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
First, the cotton fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass fiber mesh and decorative mortar finishing layer or coating. Rock wool board exterior insulation system, low thermal conductivity, good ventilation, combustion performance advantages of higher levels can be used in new construction, expansion, renovation of residential buildings and public buildings energy-saving exterior wall insulation works, including exterior insulation, fire Barrier non-transparent wall insulation and EPS external thermal insulation system. The introduction of main level A fireproofing EIFS on the present market (The following text is selected from China Building Standard Design and Research Institute " external wall thermal insulation building construction" Standard No. 10J121) Second, the foam concrete fire barrier zone 1. It is very green without the release of irritant and harmful gases; no mineral cotton floats do harm to human skin and the respiratory tract; production of toxic gases is security level (AQ1), there is no harmful gas and waste emissions and less carbon emissions; it exist not duplicate insulation demolition waste to pollute the environment.
Q:How long does it take for refractory cement to solidify?
1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
