Q:How to use fire-resistant soil?
In fact, the refractory soil is not strong. Refractory soil is clinker, there is no strength, also known as "blade mud", he is used as filling materials, the use of thickness generally not more than 3mm. Therefore, the furnace insulation can not be done.Civil boiler interior insulation, you can use "high aluminum cement", also known as refractory cement on it.
Q:Development trend of refractories
Facing the survival and development of refractory industry challenges in many aspects, serious: 1, the user industry due to the progress of science and Technology (such as iron, iron and steel industry in the direct reduction furnace, to reduce casting, slag splashing etc.), reduce refractory material consumption; 2, refractory material environmental protection and ecological requirements; 3, users of the product quality and cost requirements; 4, users risk transfer, refractory material, the design requirements of the liner construction, maintenance services, and even provide construction equipment; 5, between refractory enterprises and personnel dispute price; 6, due to the industry downturn in some countries, the decline in refractory material and the lack of education, lack of young professionals; 7, resource depletion and other raw materials.
Q:How to divide fire rating of decorating materials ?
The combustion performance of building materials is divided into the following grades by the national standard GB8624-97: level A: incombustible building materials, almost no burning material. Level B1: Flame retardant building materials, such kind of materials are effective in flame retardance. It is difficult to fire in the air in the case of open flame or under high temperature, it is not easy to spread quickly, and when the fire source is removed , the fire stopped immediately. Level B2: combustible building materials. Combustible building materials are effective in flame retardance. It will immediately burst into flames in the air in case of fire or under high temperature, and it is inclined to lead to the spread of fire, such as wooden, wooden frame, beams, wood stairs,etc. Level B3: Flammable building materials: they have no effect in flame retardance, easy to burn, fire risk is very huge.
Q:Fire insulation and fireproof insulation board materials What is the difference in performance?
What is the difference between fireproof insulation board and fireproof materials in their performance? Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of the material. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, platycodon grandiflorum as the main raw material, produced after numerous tests with advanced production technology and chemical technology. Products features fire retardant,anti-aging properties and stable performance, low deformation coefficient, environmentaly friendly, compatible with the wall base layer and plastering layer. It has good security and stability and is as durable as ordinary buildings. Strong fire resistance: Fire insulation board is made of inorganic materials (cement), fireproofing level reaching to A1. As it does not burn, it is fireproof.
Q:Which brand of AAA refractory is good?
The most famous is fire dragon. The Morgan and Lu Yang are all very good at making common thermal insulation material. The price is not very expensive, and the quality is comparatively good. The refractories are capable of good thermal shock resistance ability and chemical errosion resistance ability It is a non-metal material with a low heat conductivity coefficient and expansion coefficient. It requires high temperature in nature. The production base of silicious thermal insulation board is difficult to transport raw material. The silicious thermal insulation board is a high temperature thermal insulation material with the raw material of non-porous refractory aggregate and porous refractory aggregate, organic fiber and inorganic fiber.
Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
Q:How to determine the fire resistance rating of the aluminium-plastic panel?
The fire resistance rating of the aluminium-plastic panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
This question is a little bit extensive, because there are too much foundry ingot refractory materials.
Q:What is the definition and classification of amorphous fire resistance materials?
9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
Q:Who knows what fire heat preservation material are there?
1 thermal insulation materials with class A combustion performance Rock wool, glass wool, foam glass, ceramic foam, foamed cement, perlite and other 2. thermal insulation materials with B1 combustion performance Specially processed extruded polystyrene board (XPS) / specially processed polyurethane (PU), phenol, powder polystyrene particles. Heat-insulating material with B2 termal insulation performance Fire resistance can be thoroughly sloved by combining molded expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU), polyethylene (PE) Hairong module with glass beads (and cooperating with vitrified micro bead inventor Liu Weihua), hope my answer will help!
