Max-fire ceramic blanket products are comprised of high-strength ceramic fibers spun from alumina-silica, mechanically needled and cross-locked through a unique forming process, to produce a resilient blanket with unexcelled handling strength and surface integrity. All ceramic blanket products are completely inorganic and available in a variety of densities, thickness and temperature capabilities. Max-fire ceramic blanket products offer excellent thermal and acoustical performance, high temperature stability, low heat storage, thermal shock resistance and are unaffected by water or oil, with thermal and physical properties restored upon drying
Rock wool is a high quality thermal insulation material with low thermal conductivity. Suitable for medium and large diameter pipes; medium and small storage tanks; curved surfaces with small radius of curvature or surface irregularities. Rock wool is made of basalt,After being melted, adopted four-roller centrifugal cotton process to throw the high-temperature basalt-cotton into a 4-7 μm non-continuous fiber.
Feature :
Our rock wool PH value between 7-9, soluble chloride ion content is low, in addition to the non-corrosive steel structure and metal structure, the main features are as follows:
Thermal insulation: The thermal conductivity of rockwool at normal temperature (around 25°C) is usually between 0.03 and 0.047W/.
Non-combustion : The combustion performance of rock wool products depends on the amount of flammable binders. Rock wool is an inorganic mineral fiber, non-flammable.
Sound insulation: rock wool products have excellent sound insulation and sound absorption properties. The mechanism of sound absorption is that this product has a porous structure. When sound waves pass through, friction is generated due to the effect of flow resistance, and part of the sound energy is absorbed by the fibers. Impede the transmission of sound waves.
Can be cut according to the security, less security, easy construction
Application :
Tanks, such as gas and liquid storage, play an important role in every major area of industry. In order to preserve the material and ensure the stability and safety of the production process, it is important to maintain the temperature inside the tank. If the internal temperature of the oil tank is too high, not only the volatile loss of the oil will increase, but also the environmental pollution will be accelerated, and if the temperature is too low, the objects in the tank will become viscous so that the fluidity of the oil will decrease and the oil tank is outdoor for a long time, so when selecting the insulation material, it must have two functions: low thermal conductivity and waterproof performance
Rock wool has been tested without asbestos, CFC, HFC, HCFC, and other environmentally harmful substances. It will not be corroded or produce mildew and bacteria. It has excellent performance for the insulation of oil tanks.
As a thermal insulation material, rock wool can increase the thermal insulation resistance of the tank walls, reduce the heat transfer coefficient, and reduce the cold/heat transfer through the wall by 70%. This reduces energy loss and saves energy costs.
Ceramic Tool Types
Ceramic grade tools are typically classified into three general categories: oxide, nitride, and matrix ceramics.
Oxide ceramics are alumina-based and are generally used in roughing and finishing applications of the cast and gray irons. Increasingly, oxide ceramics are being used in dry machining applications at high speeds. This is due to the advancements within materials science, including the incorporation of whisker-based materials.
Nitride ceramics exhibit extremely high fracture toughness and are used for roughing and semi-roughing of cast irons under harsh conditions, such as when there is considerable starting and stopping that would typically increase fracturing.
CMCs contain ceramics mixed with other hard materials like cemented and titanium carbides. They can also contain reinforcing whiskers and other materials to increase wear resistance and toughness under hot machining conditions. These are commonly referred to as SiC-whisker reinforced. Alumina reinforced with SiC whiskers is the toughest and most resistant to thermal shock of the oxide-based ceramics due to the extremely high tensile strength of the SiC whiskers. It offers the additional benefit of being able to be run without coolant, thus making dry machining a common application while also being able to offer an increase in machining rates up to 800%.
All ceramic cutting tools have excellent wear resistance at high cutting speeds.
There is a range of ceramic grades available for a variety of applications.
Oxide ceramics are aluminum oxide-based (Al2O3), with added zirconia (ZrO2) for crack inhibition. This generates a material that is chemically very stable but lacks thermal shock resistance.
(1) Mixed ceramics are particles reinforced through the addition of cubic carbides or carbonitrides (TiC, Ti(C, N)). This improves toughness and thermal conductivity.
(2) Whisker-reinforced ceramics use silicon carbide whiskers (Siew) to dramatically increase the toughness and enable the use of coolant. Whisker-reinforced ceramics are ideal for machining Ni-based alloys.
(3) Silicon nitride ceramics (Si3N4) represent another group of ceramic materials. Their elongated crystals form a self-reinforced material with high toughness. Silicon nitride grades are successful in gray cast iron, but a lack of chemical stability limits their use in other workpiece materials.
These benefits lead to increases in efficiency. For example, many machinists would slow cutting speed if temperatures were to approach maximum carbide limits. It is the opposite for ceramic tools, which excel in higher temperature conditions.
