Q:Who knows the roofing fireproofing and waterproof material?
Colorful glass fiber asphalt shingles the roofing through special materials treatment just like wearing a waterproof, fireproof coat, water rolling down from the roof is similar to the effect of lotus leaf drops, the wall will be always in the dry state, having excellent waterproof, mould proof, efflorescence and weathering. It can prevent the growth of moss and keep the surface clean. And let your roof does not change color for a long time. Colorful fiberglass asphalt shingles materials are widely used in: All types of buildings roofing waterproofing, leak, fire, pollution, wind, and mould proof and moisture-proof of libraries and archives. The color retention of ancient architecture and protection of human cultural relics. Through the number of ten million square meters of engineering applications and two decades of practical test, it welcomed by users.
Q:What is the use of refractory?
Some is insulated for personnel safety, some is to save heat loss and conserve energy, and some is used as lining of kilns. Because of its light weight, I recommand it to you and I am engeged in ceramic fiber, just an advertisement.
Q:Where is the distributing center of refractory materials in China?
The infrastructure is perfect, service and refractory chemical industry professional market ancillary services, information, transportation, food, housing, and other one-stop perfection. The business service center, Yongan business city, Fukang company, Xu Bai Anlong logistics center and the market has been basically formed, the market in more than 200 dressing rooms at the end of September put into use, logistics center, warehouse industry nearly twenty thousand square meters can use for customers. The Fasthotel, the dormitory and the information center will be ready for delivery, and large transport teams will be built to provide accommodation, freight and other convenient services for the owners.
Q:What is the fire endurance of fireproof glass cotton?
Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass silk λ=0.043W/m2K. good fireproof performance, it's fire-resistant capacity is more than 1000 ℃.
Q:How should fireproof building materials be ranked?
According to our national standard GB8624-97, the combustion performance of building materials are divided into the following levels: A class: Incombustible building materials: the material is almost incombustible. B1 class: Flame-retardant building materials: they are better in fire retardation. It is non-combustible when meeting open fire in the air or under high temperature, and it is difficult for the fire to spread quickly. Besides, when the fire source is removed, combustion stops immediately. B2 class: Combustible building material: It has certain fire retardation. In case of open fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as the spread to wooden pillars, timber roof truss, timber beams, wood stairs, etc. B3 class: Flammable building material: It has no fire retardant effect at all, but is highly flammable with high fire risk. Hope my answer can be accepted.
Q:What is refractory brick?
Capability1. Refractory brick is also known as firebrick. It is faint yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
Q:Which kind of furnace hearth refractory is better?
hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.
Q:How to divide the fire resistant level of EVB?
Inorganic materials: Level A incombustible material is mainly divided into three levels, which attributed to two types of materials! Inorganic materials: Rock wool, foam cement, vitrified micro bead, foam glass organic: Eps xps polyurethane phenolic aldehyde, polystyrene particles are divided into two manufacturing techniques including field fabrication and pre-production polyurethane - now sprayed, precast slab eps, xps, phenol - now posted, precast slab (composite board)
Q:Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
There are a lot of silicon manganese alloy manufacturers, production market is relatively large, the manganese content in manganese alloys between 63 to 70 or more common
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
