Aluminosilicate refractory fibres and products market analysis

The production of aluminum silicate refractory fiber is due to the high cost, and the current application is mainly concentrated in the industrial production field. There are not many applications in the field of construction. It is mainly used in industries with coal, oil, gas and electricity as energy sources. The kiln's inner lining and thermal insulation materials can also be used as heat-resistant reinforcing materials and high-temperature filter materials. As a lining material, it can be used in thermal insulation linings of atomic energy reactors, industrial kiln furnaces, metallurgical furnaces, petrochemical reaction devices, and heat insulation linings of metal material heat treatment furnaces and ceramics kiln.

The existing insulation and heat insulation lining structure has refractory fiber veneer lining, refractory fiberboard/fire resistant fiber blanket fiber lining, refractory fiber pouring material lining, prefabricated modular fiber lining, refractory fiber spraying lining, refractory fiber castable Lining and so on. As a heat insulation material, it can be used for filling heat insulation in industrial furnace walls, filling heat insulation between furnace refractory bricks and fireproof thermal insulation bricks, air jet ducts for airplanes, heat insulation of jet engines and other high temperature pipelines, and slow processing of steel pipe manufacturing processes. Cold large diameter welded steel pipe and large diameter pipe bending processing.

In addition, aluminum silicate refractory fiber can also be used for the insulation of long-distance gas pipelines. It has been proved by the experiment of China Petrochemical Co., Ltd. Guangzhou Branch that when using high-quality aluminosilicate refractory fiber insulation, the thickness of the insulating layer is not less than 180mm Can meet the f530mm × 20mm long distance gas pipeline insulation optimization requirements.

Aluminosilicate refractory fiber and its market applications:

1. In practical applications, the raw cotton fiber can be directly used for industrial furnace expansion joint filling, furnace wall insulation, sealing materials, and making fire-resistant paint and castables; aluminum silicate refractory fiber felt is semi-rigid plate-like fireproof Fiber products have good flexibility and flexibility. The strength at room temperature and high temperature can meet the needs of construction and long-term use, and are mainly used for industrial furnace wall lining.

2. Due to its soft formability during construction, the aluminum silicate refractory fiber wet felt can be applied to a variety of complicated heat-insulating parts. After drying, it becomes lightweight, surface-hardened, and has an elastic insulation system, which allows anti-wind erosion performance. Up to 30m/s, superior to aluminosilicate refractory fiber felt; aluminosilicate refractory fiber acupuncture blanket without binder, excellent mechanical properties, widely used in various types of industrial furnaces and high temperature pipe insulation;

3, aluminum silicate refractory fiberboard is a rigid refractory fiber products, due to the use of inorganic binder, the product has excellent mechanical properties and wind erosion resistance, generally used to build industrial furnace and high temperature pipe wall lining of the hot surface;

4. The shaped products of aluminum silicate refractory fiber prefabricated components are mainly used for masonry furnace linings, and the construction and furnace construction is convenient and fast; the largest amount of ceramic fiber special-shaped products is aluminum silicate refractory fiber tube shells, which can be used for making small electric furnace furnaces. Foundry riser bushings and other fields; aluminum silicate fiber paper is generally used for connecting joints in expansion joints, burner joints, and pipeline equipment. Aluminosilicate refractory fiber rope is mainly used for non-bearing high-temperature insulation materials and sealing materials.
