Q:In entering fire door, which material does well?
About this, I personally advice you to take a look at the building materials market, where will be many options and comparativity would be much better.
Q:What's the material of fireproof and wear-resisting floor?
Hello! Fireproof floor is non-flammable, wear resistant, and beautiful. It is made by construction steps and has many advantages: seamless, environment friendly, non-toxic, resistant to abrasion and corrosion, waterproof, dustproof, beautiful in appearance with integriality and no irritating odor The material of fireproof floor is in the form of liquid which will be in the shape of solid membrane after the completion of construction. It can be widely applied to the ground in the factory, residential ground or walls, and large areas like institutions and warehouses with high requirement on fire prevention. It can also be used in the field with no requirement on fire protection for it is beautiful in apperance and just like epoxy floor, and with good cost performance, it is a kind of commonly used decorative material. Hope it's helpful for you!
Q:Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Hello. 1. Gaps between the curtain walls and floors of all tier and partitions outer edge should be sealed with non-combustible material or flame retardant materials. Filling material can be rock wool or mineral wool, whose thickness should be not less than 100mm and should meet the designed fire endurance requirements, forming fire and smoke prevention areas between floors and rooms. Fireproof layer should use galvanized steel bearing with thickness of not less than 1. 5mm, and should not use aluminum plate. Gaps between bearing plate and main structure, curtain wall structure and the bearing plate should be sealed by fireproof sealant; fireproof sealant should has fireproof inspection reports granted by statutory testing organizations. 2. When building designs requiring transparent effect of fire compartment and separation, monolithic fire-resistant glass or hollow and laminated fire-resistant glass nade by monolithic fire-resistant glass can be adopted. 3. Windowsills-free curtain walls, incombustible entities skirt wall or fireproof glass wall whose fire endurance is not less tan 1.0 hour and height is not less than 0.8m should be set on the outer edge of each floor. The thickness of reinforced concrete floor or height of the side beams should be counted when calculating the height of the skirt wall. 4. Fire protection layer should not contact directly with the glass curtain wall, and the side towards the glass of fireproof materials should be covered with the decorative material. 5. Glass units of the same curtain wall should not cross two fire compartments.
Q:How to divide the materials according to the National Fireproofing Material Standard?
Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.
Q:How is the division of the fire resistant level of the rock wool board?
The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier between two windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;
Q:What antioxidant will be used in refractories?
Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
Looking for refractory materials network, you can conduct online transactions, funds guaranteed
Q:What are the new refractories? What are the features? How about their application and development?
In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
