Q:What are the common refractory insulation cotton material?
High aluminum, clay brick, aluminum silicate fiber module and so on, inorganic types are glass wool, rock wool, foam glass etc.. Organic: the best one is phenolic foam, compround phenolic foam cement layer is a-level. Aerated concrete and other refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and compround thermal insulation material, expanded perlite, foam clay It is applicable for buildings that have high requirement for fire proof level, foamed concrete, volcanic ash glass.
Q:Physical and chemical indicators of various refractory.
it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
Q:Refractories for iron-making blast furnace?
Cement kilns?
Q:Can anyone tell me what is A-leve fireproof material?
Combustion performance of materials can be divided into: A-level, B1-level, B2-level and B3-level, which respectively refer to noncombustible, difficult-flammble, flammable and inflammable materials. Building materials can be divided into four grades based on combustion performance (noninflammability, flame retardancy, flammability and inflammability). According to the stipulation of "Specification of Fireproof Design for Buildings" (GBJ16-1987) (2001 revised edition), fire hazard of production or storage should be divided into A-level, B-level, C-level, D-level and E-level. In "Specifications on Fireproof Design for Petrochemical Enterprises" (GB50160--1992) (1999 Revision), it also stipulates that fire hazard should be classified on the same basis of subtsance danger in usage, production or storage. According to different fire hazard, requirements and measures of oreventing and restricting fire explosion can be put forward from the aspects of fire separation distance, fire resistant rating of buildings, allowed floors, safe evacuation, fire fighting facilities and other aspects.
Q:What's the fire endurance of A grade fireproof glass curtain wall?
The following is fire endurance of A class fireproof glass curtain wall. Fire endurance of the fire window: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke insulation in case of fire. Hope it's helpful for you.
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:Which brand of AAA refractory is good?
Rong Sheng Kerui quality refractory Zhengyuan Shenzhou Saatchi these brands are very good, with high refractoriness, durability and with a good cost performance. Get the majority of customers' recognition.
Q:What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q:Which brand of thermal insulating refractory is good?
The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Refractories are non-metallic materials with good resistance against thermal shock and chemical erosion, low heat conductivity coefficient and expansion coefficient. It requires high temperature resistance in nature. It is difficult to transport suc materials in silicious thermal insulation board production base. Silicious thermal insulation board is a kind of thermal insulation material during casting process. Raw materials are non-porous refractory aggregate, porous refractory aggregate, organic fiber and inorganic fiber.
Q:What are the specifications of refractory kilns ?
There several points need to be noted ① selection of body material. The refractory lining of the front kilneye turns gelid and hot rapidly and frequently, so the temperature is in the range of 800 ℃ ~ 1250 ℃, allowing it to withstand wear of the cement clinker and corrosion of the cement base. The body material of castable refractory must be chosen according to its service conditions, in order to ensure that it is cheap and easy to use. ② the selection of admixture. Shapeless refractory materials are typical in-situ reaction refractories. Therefore choosing admixtures is very important and must ensure workability, baking performance, and excellent material properties. Admixture for Kiln refractory castable includes dispersants, accelerators, plasticizers, sintering agent, bulking agent and antidetonant. Materials of sintering agent are animate clay, zirconite, titanium dioxide and Peng compounds. Such substances produce a certain amount of mullite crystals, zircon phase, titanium aluminate crystal and inconsistent melting compounds (2Al2O3 • B2O3), etc. under the operating temperature and in situ reaction. They are accompanied by volume expansion and microcracks, enabling it to compensate for the sintering shrinkage, so that the casting material can have sintering strength, corrosion resistance and good thermal shock resistance. In summary, the refractory castable material for the rotary kiln shall be determined in accordance with its service conditions. It is recommended that clients should also communicate with technical personnels and sales staff about some facts of the rotary kiln when buying it, so that they can get the satisfying rotary kiln.
