CN102659346A - Production method of coal ash stair handrail - Google Patents

Abstract

The invention discloses a production method of a coal ash stair handrail. The raw materials include, by ratio, 70% of coal ash, 8% of polyvinyl choride, 12% of epoxy resin, 3% of stearic acid, 4% of calcium stearate and 3% of paint. The production method includes weighing all the materials according to the ratio of the raw materials, fully mixing and stirring the materials (except the paint), transferring the mixed material to a blank mould for extrusion forming, subjecting the formed semi-finished product to heating and maintenance, sending the blank after maintenance to a drying box for drying, and subjecting the dried blank to paint backing. The stair handrail produced through the method has the advantages of being light in weight, corrosion and weather resistant, attractive and elegant in appearance, not easy to deform and the like.

Description

A kind of working method of flyash banister

Technical field

The present invention relates to a kind of working method of banister, particularly relate to a kind of working method of flyash banister.

Background technology

Flyash is to receive the thin ash of catching the flue gas behind coal combustion, and flyash is the main solid waste that the coal-burning power plant discharges.Flyash is one of bigger industrial residue of the current discharge capacity of China, and along with development of electric power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; If entering water system can cause the river to silt up, and toxic chemical substance wherein also can work the mischief to human body and biology.Banister generally adopts metallic substance such as Stainless Steel or iron skill to process, and it is yielding to bump, and production cost is high, is not suitable for mass consumption.

Summary of the invention

The present invention provides a kind of working method of flyash banister, and the flyash that utilizes power plant to discharge is aggregate, production energy-conserving and environment-protective, inexpensive banister.

The present invention has adopted following technical scheme:

A kind of working method of flyash banister, its composition of raw materials ratio is: flyash 70%, SE 8%, epoxy resin 12%, Triple Pressed Stearic Acid 3%, calcium stearate 4%, paint 3%.

A kind of working method of flyash banister may further comprise the steps:

1) takes by weighing various materials in the composition of raw materials ratio;

2) the above-mentioned material that takes by weighing (except that paint) thorough mixing is stirred;

3) mixture is transported to carries out extrusion molding in the base substrate mould;

4) with the maintenance of heating of the work in-process of moulding;

5) base substrate of maintenance being accomplished is delivered in the drying baker and is dried;

6) dried base substrate being carried out baking vanish handles.

The banister that present method is produced is compared with existing common banister, has following beneficial effect: with flyash starting material, and nontoxic, radiationless, pollution-free, utilization of waste material, energy-conserving and environment-protective.Can be used for concrete structure stair, spiral stairs, steel wood finished product stair, glass stair etc., have in light weight, corrosion-resistant, weathering resistance, advantage such as elegant in appearance, not yielding.
