- Q: Who knows the refractoriness of high temperature lightweight firebricks?
- Hefei Jiu oak decor help you answer; the biggest feature is refractory: refractoriness 700.
- Q: How about the prospect of refractory material?
- Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
- Q: What is acid refractory material?
- In fact, with the content of zirconia refractory multiple theory should also be acid refractory
- Q: Is fireclay corrosive?
- No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
- Q: What's the fire endurance of hollow brick?
- For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.
- Q: What's the organzational structure of refractory material?
- Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- combustion performance of building decoration materials should be divided into four levels: A level, non-flammable; Class B1, flame retardant; B2 level, flammability; B3 level, flammable. Choose the materials above B1level. Thank you
- Q: Who knows about the fire endurance of grade C fire doors?
- It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. I hope my answer can help you.
- Q: What is refractory cement?
- Refractory cement is also known as aluminate cement, whose major mineral are monocalcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminate as well as a small amount of dicalcium silicate (2CaO · SiO2), etc. The advantage is that it is easy to use, able to harden if mixed with added water without other binding agent usually. Refractory aggregate and powder can be added into it. If you use refractory cement purely, it will produce a lot of cracks after high temperature.
- Q: Why the corundum can be used as refractory
- Do you need white corundum Its main chemical element of corundum is the 99.3% aluminium oxide and it is sintered byelectric furnace, so it can be used as a refractory raw material, the other can also be used as grinding wheel. It is very useful
