Description

 

The particles that are used in the pharmaceutical industry are still micron size only because the nano powders in the pharmaceutical industry are still in the research stage for most of the cases but in some cases of laparoscopy and angioscopy nano powders have been used but it are not cost effective. In the recent years the demand for nano powders are increased drastically because of its wide range of applications by producing Nano powder with metals like aluminum, iron and copper. This Novel technology is used in the production of aluminum powder which has applications in aviation industry.

 

Applications

  1. Metallurgical deoxidizer

  2. High temperature resistant materials

  3. As abrasive, abrasive tools can be used to such as grinding wheels, whetstones, grinding head, sand tile etc

 Advantages

  1. Corrosion resistance, high strength, high hardness

  2. Good wear-resisting performance,resist to shock

  3. Stable chemical performance, high thermal conductivity, high resistant temperature

Q:What are the types of steel refractory materials
The major category is classified as permanent layer, working lining. Specific varieties: Air permeable brick (corundum). steel ladle brick (magnesia or corundum), permanent layer castable (high alumina), reinforcing material for ladle bottom, repair material for the edge of tank and so on.
Q:What are the features of construction class A fire resistant door ?
Residential building: If the building height exceeds 100 meters, the combustion performance of thermal insulation material should be A level. Other civil building: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission
Q:What's the fire resistance test method of doors and roller shutters?
Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
Q:how does the fire endurance of first rate fire resistant window?
the classes are different. class A window not less than 1.5 hours, and the time is short, class B window not less than 1 hours, with shorter time, Class C window not less than 0.5 hours.
Q:Who knows how many poured refactory material are there?
Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.
Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate refractory fiber board has following characteristics:1. the structure is more even than natural wood. it avoids rot, moth-eaten and other problems, 2. fiber board has small expansion and contraction, which is easy to be processed. 3. its smooth surface is easy to paste a variety of finishings and you can make furniture more beautiful. Decorative wood-based panel is to embellish their homes. I hope it is useful to you!
Q:What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.
Q:What's the fire retardant material of roller shutter fire resistance door ?
Core board of fire door materials are composited by inorganic materials, and the main components are perlite, inorganic adhesive and other special formula. It has flat and smooth surface, unibody. It is fireproof, sound and thermal insulating. It has passed tests of Tianjin Fire Research Institute and Beijing construction institute.
Q:how is the high-temperature flame-retardant fibre board?
------ Different category of high temperature materials including refractory and heat-resistant material, inorganic compounds, high-molecular polymer. refractory usually refers to an inorganic material that can endure temperature above 1580 ℃ . They are for building kiln, combustion chamber and other buildings that require heat resistance materials. It is generally made of quartz sand, clay, magnesia mineral, dolomite.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
Ceramic pottery ceramic collectively known species of high water absorption and low-grade sinter clay brick, tile-like material; high stone kinds of porcelain clay plus clay and other raw sintered body strength, low water absorption bowls, plates and other kinds of refractory high temperature structural materials are all non-machine ceramic refractory metal material belonging to a broader definition of ceramic refractory ceramic can be attributed to the high temperature ceramic refractory.
