Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
If there is only a small local, bake according to the overall it is really troublesome, water wall repair point of direct drive estimation problem is not large, the water wall itself is used to slag slag slag principle, can also play the role of refractory materials.
Q:What kind of material is refractory fiber?
Refractory fiber is good infrared radiation material with good thermal capacity and infrared heating effect. The use of firefractory fiber products can effectively save energy. It is an ideal energy-saving material. Practice has proved that using refractory fiber in continuous industrial heating furnace can save energy of over 15%, and using it in interval industrial heating furnace, it can save energy of more than 30%, while increasing productivity and improving product quality. And make the furnace structure light, large-scale with good comprehensive performance. Refractory fiber is soft and flexible and it is also ideal sealing material. As it has good insulation, sound absorption, anti-oxidation, oil and water resistance and easy construction, it is widely used in metallurgy, building materials, petroleum, chemical, shipbuilding, electric power, aerospace and other fields.
Q:Refractory factory grinding brick dust harmful to the body?
The effect is very large and belongs to lung disease.
Q:Who knows the new fireproof and thermal inuslation matertial?
Ceramic foam insulation board, XTP vacuum insulation panels and a variety of composite insulation panels, etc. Relatively speaking, the inorganic insulation board is a trend. In terms of the overall performance, the cost performance of the foam insulation board is higher. XTP has the best performance, but with a little trouble in construction. Because of the vacuum characteristics, transportation and installation process should be very careful.
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:How to solve the shell, the crack problem of refractory material in the process of forming.
Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
Q:which is better as household fireproof material ?
If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified micro bead thermal insulation mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.
Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
A level fire resistant steel structure building steel column cannot be constructed with super thin steel structure fire retardant coating, because the ultra thin steel structure fire retardant limit is less than 3 hours. Thin fire retardant coating for steel structure is water borne fireproof coatings painted on the surface of steel structure. It will form carbonized fireproof heat insulation protective layer to insulate oxygen and delay the speed of heating steel structure when it catches on fire, avioding the rapid temperature rise of steel structure and increasing its fire resistant limit. Fire resistance performance: The 2mm coating ≥ 60min, 3mm 100min.
Q:Why do magnesium oxide refractory bricks can be made into refractories?
The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .
