Q:Who knows what kind of material the fire-proof plate use, and is it good?
It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight aggregate, adhesive and chemical additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
First, external wall thermal insulation material: 1. silicate insulation material; 2. glue powder polyphenyl granule; 3. cement cystosepiment with the use of steel wire gauze (polystyrere); 4. extruded sheet; Second, roofing materials: 1. xps extruded sheet; 2. EPS foam board; 3. perlite and perlite brick; 4. vermiculite and vermiculite brick; Third, materials for heating power and air conditioners: polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Fourth, steel structure material: polystyrene, extruded board, polyurethane board, glass cotton lap felt, etc.
Q:What are the raw materials of refractory concrete ?
Q:How much is the duration of fire resistance of the porous brick shale?
It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃, I hope my answer will help you a lot.
Q:The history of refractory material
Q:What are the specifications of fireclay bricks?
Standard sizes of refractory bricks in our country are: 230mm × 114mm × 65mm; standard density: 1, Diatomite insulating bricks 0.7 g / cubic centimeter; 2, Clay bricks 2.9 g / cubic centimeter; 3, High alumina brick 3.2 g / cubic centimeter. You can convert according to the actual volume, and the reference value can be calculated.
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's the fire endurance of fireproof panel?
fire endurance of fireproof panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
While the refractory ceramic fiber cloth is different in high temperature resistance, and in general it can endure the high temperature of more than 1000℃. Ceramics in daily use and art ceramics: Bone china and Guangdong chinaware can generally endure the highest temperature of 1100℃. Jingdezhen porcelain and ceramics: They can generally endure the highest temperature of 1280℃-1340℃, and some special ones can endure the highest temperature of 1400℃. Industrial ceramics: Some of them can endure the highest temperature of about 2600℃. (alumina ceramics: their melting point is 2050℃, and boiling point is 3000℃).
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.
