Q:What is the fire endurance of ceramsite concrete blocks?: What is mentioned in fire?safety?rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated?concrete?block" DB / T29-128.

Q:What does refractory mean?: Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.

Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?: The new external wall fireproof and thermal inuslation matertials have both the advantages and disadvantages. Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;

Q:Who knows about the criteria of fireproof and thermal insulation materials?: Seven levels are divided according to "The classification of combustion performance of building materials and products", namely, A1, A2, B, C, D, E, F. It mainly refers to the combustion performance of materials. You can check on this standard for the specific dividing evidence. There are detail charts which mainly describe that whether there is drip or not, the ignition time, continuous burning time and so on.

Q:Urgently!! Refractory problems, online, etc.: I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?

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:Can quantitative feeder be used in refractory plant? Thank you: Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants

Q:The effect of a high content of water in liquid resin exerted on refractory material?: For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.

Q:What is streaming fireproof material?: Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.

Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?: It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
