- Q: How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
- Q: Physical and chemical indicators of various refractory.
- it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
- Q: What a blast furnace refractories generally?
- Usually metal anchorage plus wear-resistant refractory spray paint. at the middle part we use high alumina bricks, corundum bricks. high duty refractory is important in improving bosh furnace lining.
- Q: What is the new fireproofing standard of external wall thermal insulation materials?
- The civil builduing with thermal insulation material for exterior wall in the scope of construction fire safety design and fire inspection should put the combustion performance of building thermal insulation material for exterior wall into the content of review and acceptance. The civil builduing with thermal insulation material for exterior wall beyond the prescribed scope of Article 13, Article 14 of "Fire Supervision and Management Regulations of Construction Project" (Ministry of Public Order No. 106) should all be included in the scope of checks. Before released the new standard, it should be strictly implemented the Article II of "Provisional Regulation of Civil Building External Thermal Insulation System and Exterior Wall Decoration Fire Prevention" (known through word [2009] No. 46), the civil builduing thermal insulation material for exterior wall uses level A combustion performance material. I hope my answers are helpful to you.
- Q: Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
- There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
- Q: What is neutral refractory? Can refractory suppliers tell the main components of it?
- The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.
- Q: What kinds of fireproof materials does the safe use?
- Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
- Q: Are there any differences between insulation and refractory materials ?
- I will explain to you in a simple way. Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc. I hope you can understand it.
- Q: Who knows how many poured refactory material are there?
- Pouring refractory material can be classified into the followings according to the body density: Heavy (> 2.0g\cm3), medium heavy (1.0-2.0g\cm3), light (0.4-1.0g\cm3); by binding agent: Combination of hydration, chemical binding, condensation, hydration and condensation: Clay, high alumina, silica, magnesia, alumina magnesia, magnesium and chromium, magnesium zirconium, silicon carbide etc.. Clay brick, high alumina brick, bead brick, silica brick, light mullite, alumina hollow spherical brick, oxidation zirconium hollow spherical brick, corundum brick, magnesia brick, magnesia brick, magnesia alumina spinel brick, magnesia chrome brick and so on
