Q: How to do environmental impact assessment for refractory Co., Ltd.: 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.

Q: For refractory knowledge. What is the ratio of clay ramming?mass?: Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK

Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.: who knows the classification of fireproofing glasses, how long is the fire-resistant time?

Q: Ask some questions about refractories: Is a kind of refractory material, jargon called hook materialThe iron runner: a combination of the super high Los resistant technology, aluminum and corundum, silicon carbide and other raw materials, to high-quality composite binders and additives, strict proportioning, elaborate. The utility model has the advantages of good slag resistance, good thermal shock resistance, long service life, convenient use, simple construction, and obvious reduction of labor intensity of workers.Application: it is suitable for blast furnace tapping system.

Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.

Q: how does the fire endurance of first rate fire resistant window?: Not less than 1.5 hours

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: Refractory inquiries: Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.

Q: What refractory materials are used in power plant: Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
