Q:Who knows the fire endurance of rock wool color plate?
I'm glad to answer your question and offer you some of my experiences, for reference only. In fire safety rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
Q:Introduction to refractory material
Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
Q:What are the refractories for converter?
Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
Q:can slag tailings be used to be the base materials of refractory materials ?
perhaps not, because it has many pores.
Q:Fire resistance and evaluation of refractory for casting
Because of their different shapes and conditions, various refractories are used to explain their fire resistance with different indexes, and the test methods are also different. In general, the refractoriness of unshaped refractories; the softening temperature of formed refractory products; the change of the reheating line of heat insulation materials at high temperature.
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:How many grades of fire rating are there for interior decoration materials?
It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.
Q:What's the A grade fireproofing material?
A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:How long is the fire-fighting time of A class fire resisting window?
Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
Q:Fire rating of decoration materials
All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
