FACTORY:
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- What material it is. There are many kinds of refractory materials, and I basically understand all petrochemical refractory.
- Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- Yes. After moulding by casting in the firing of 1450 ° degrees.
- 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.
- Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
- I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
- Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
- Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
- Q: Which fire-resistant materials have good viscidity?
- The viscidity of fire-resistant materials is also known as the binding performance of fire-resistant materials. It can be divided into chamotte and chemical binder. Both can work at normal or high temperature. The most commonly used chamotte are soft clay and aluminate cement. The commonly used chemical binders include sodium silicate, phosphoric acid, aluminum sulphate, aluminium phosphate, phenolic resin, etc. Fire resistant material is a complicated and overloaded system and we cannot know its materials and chemical components from the name alone. Both gunning mix and repair mix contain binder components. If they can used after adding water, then they may contain clay or fire resistan aluminum silicate cement.
- Q: What are the chemical composition of refractory cement?
- Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
- Q: Does anyone know what is a lightweight refractory material?
- Light weighted castable is one of the kind.
- Q: Can anyone say something about what A-level fire-proof decorative material is?
- The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, monomer A-level includes rock wool, ultra-thin insulation panel and the like. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear.
- Q: What are the main materials in concrete fireproofing material?
- fireproofing materials mainly consist of class A incombustible?material and class B1 nonflammable material. Class A incombustible?material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
