Q:What do RH and DH stand for in refractories?
The English abbreviation depends on where it is used, and the meaning is judged according to the actual situation. Some are not standard, even the abbreviation of Chinese phonetic alphabet. The dictionary looks up the meaning of these two abbreviations and writes them according to the specific situation!END: Arrow-head definition file (CorelDraw) Arrow-head definition file (CorelDraw)End: endocrine endocrine secretions.END: Endorphin endorphinsEND: End of Data data.END: Electronic Null Detector electronic instrumentEND: Endorse/Endorsed/Endorsing/Endorsement / / support / endorsement endorsement endorsementEND: European Nuclear Disarmament European nuclear disarmamentEND: Exchange Name Documentation exchange file nameEND: Enhanced Network Driver (multiple protocols on a single driver) enhanced network driver (multi protocol driver in a single)
Q:Who knows how many fire heat preservation material are there?
They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
Q:What is glass furnace used high-grade refractory materials?
Corundum brick, such as alumina hollow ball brick. In addition, in the key parts of the glass furnace needs to use chromium zirconium corundum material. I'm salesman of zibo lei bao refractories company. The softening temperature of corundum mullite brick is 1500 degrees. So glass melting furnace needs to use refractory materials which high temperature resistance is more than 1600 degrees.
Q:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
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 are the advantages of refractory material?
Jingute WHL type, GDS type
Q:Who knows about the B-level fireproof insulation materials?
Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
Q:Why the refractories should be waterproof and wetproof
It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
