Problems solved by technology

If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms
Stair handrails are generally made of metal materials such as stainless steel or iron art, which are easily deformed in the event of collision, and the production cost is high, so they are not suitable for mass consumption

Embodiment Construction

[0014] A kind of production method of fly ash stair handrail, its raw material formula ratio is: fly ash 70%, polyvinyl chloride 8%, epoxy resin 12%, stearic acid 3%, calcium stearate 4%, paint 3% %.

[0015] A kind of production method of fly ash stair handrail comprises the following steps:

[0016] 1) Weigh various materials according to the ratio of raw material formula;

[0017] 2) Fully mix and stir the above-mentioned weighed materials (except paint);

[0018] 3) transfer the mixed material to the green body mold for extrusion molding;

[0019] 4) heating and curing the formed semi-finished product;

[0020] 5) Send the cured green body to the drying box for drying;

[0021] 6) Carry out baking varnish treatment to the dried green body.

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

technical field [0001] The invention relates to a production method of a stair handrail, in particular to a production method of a fly ash stair handrail. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. Fly ash is one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to human beings and organisms. Stair handrails are generally made of metal materials such as stainless steel or iron art, which are easily deformed in the event of collisions, and the production cost is high, so they are not suitable for mass consu...
