Abstract
The invention discloses a degreasing process of a steel pipe scaffold. The process comprises the following steps: 1) conducting magnetization treatment on the steel pipe, cleaning with caustic soda solution with concentration of 0.2-0.5% 2-3 times, and then cleaning with hydrochloric acid solution with concentration of 0.2-0.5% 2-3 times; 2) conducting ultrasonic cleaning on the steel pipe by the ultrasonic equipment, and then soaking the steel pipe into a pool to for 20-30 min; 3) immersing the steel pipe in a tank containing kerosene for 20-30 min, then taking out the steel pipe, placing the steel pipe on a cleaning shelf, and wiping the inner wall and the surface of the steel pipe with butyl acetate; 4) rinsing and conducting demagnetization treatment at a temperature of 300 to 350 DEG C; and 5) rinsing the steel pipe with tap water, drying by air inducing equipment, carrying out chromium plating on the surface; and rinsing and drying. The invention has the advantages of simple operations and easiness for batch production; and the steel pipe treated by the process has grease completely removed.
Description
Technical field
The invention belongs to scaffolding field, particularly relate to a kind of degreasing process of steel pipe for scaffold.
Background technology
Scaffolding refers to that working-yard is the various supports that operative also solves vertically and horizontal transport is set up.The generic term on building circle, refers to construction site be used in the higher place that cannot directly construct of exterior wall, inside fitting or floor height.To work up and down mainly for workmen or perimeter security net is gone along with sb. to guard him and high-altitude installation component etc., be widely used in departments such as advertising, municipal administration, traffic road and bridge, mines.Existing steel pipe uses a large amount of commercial grease as lubricant and refrigerant in process of production, and this requires very high to degreasing process.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide a kind of degreasing process of steel pipe for scaffold, to solve the problem.
Technical problem solved by the invention can realize by the following technical solutions:
A degreasing process for steel pipe for scaffold, comprises the steps:
1) steel pipe is carried out magnetization treatment, first clean 2-3 time with the caustic soda soln that mass concentration is 0.2-0.5% after magnetization, then clean 2-3 time with the hydrochloric acid soln that mass concentration is 0.2-0.5%;
2) adopt ultrasonic equipment to carry out ultrasonic cleaning to steel pipe, then put into pond and invade bubble 20-30 minute;
3) steel pipe is immersed be marked with in the groove of kerosene and embathe 20-30 minute, then take out steel pipe and be positioned on rack for cleaning, by N-BUTYL ACETATE wiping steel pipe inner wall and appearance;
4) carrying out demagnetization process after rinsing, is demagnetize to steel pipe under the condition of 300-350 DEG C in temperature;
5) use tap water to carry out rinsing, then use air inducing equipment to dry up, dry up rear effects on surface and carry out electrodeposited chromium; Plating afterwash is dried.
In a preferred embodiment of the invention, in described step 1), the optimum concn of caustic soda soln is 0.4%, and the optimum concn of hydrochloric acid soln is 0.4%.
In a preferred embodiment of the invention, the best time of embathing in described step 3) is 25 minutes.
Compared with prior art, the invention has the advantages that:
The present invention is simple to operate, and easy outputization is produced, and the steel pipe through process of the present invention can remove grease completely.
Embodiment
