Embodiment Construction

[0022] like figure 1 As shown, the present invention proposes a spraying process for enhancing the high-flow anti-oxidation and anti-fouling coating on the inner wall of the bellows, including the following steps:

[0023] S1. Add polyurethane paint in paint storage tank 5;

[0024] S2. Pass the paint pipe 3 through the extruder head 7 and the water jacket 6;

[0025] S3, move the bellows 1 to the outer circumference of the water jacket 6;

[0026] S4, start the spraying machine 4, the spraying machine 4 extracts the polyurethane paint from the paint storage tank 5, and transports the polyurethane paint to the nozzle 2 through the paint pipeline 3, and the nozzle 2 sprays the polyurethane paint in the form of a paint spray 21 to the inner wall of the bellows 1, A layer of polyurethane film coating is formed on the inner wall of the bellows 1 .

[0027] The polyurethane coating concentration, nozzle 2 gap and spraying pressure are all controllable; by controlling the polyure...

Abstract

The invention relates to the field of corrugated pipe treatment, in particular to a spraying process and a formula of a corrugated pipe inner wall enhanced high-flow anti-oxidation anti-dirt coating. The method comprises the following steps: S1, adding a polyurethane coating into a coating storage tank; s2, enabling a coating pipeline to penetrate through an extrusion machine head and a water jacket; s3, the corrugated pipe is moved to the periphery of the water jacket; and S4, the spraying machine is started, the spraying machine extracts the polyurethane coating from the coating storage tank and conveys the polyurethane coating to the spraying head through the coating pipeline, the spraying head sprays the polyurethane coating to the inner wall of the corrugated pipe in a coating mist spraying mode, and a polyurethane film coating is formed on the inner wall of the corrugated pipe. Protection on the inner wall of the corrugated pipe can be improved, and the inner wall of the corrugated pipe is not prone to abrasion and corrosion.

Description

technical field [0001] The invention relates to the field of corrugated pipe treatment, in particular to a spraying process and formulation of a reinforced high-flow anti-oxidative and anti-fouling coating on the inner wall of a corrugated pipe. Background technique [0002] Drainage pipes are divided into plastic drainage pipes, concrete pipes and reinforced concrete pipes, etc. Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage, etc., and are specifically used for soil and water conservation of slope development slopes; municipal engineering, water purification plants, sewage Water supply and drainage in factories, garbage dumps, etc.; tunnels, underground drainage, etc. Corrugated pipe is a kind of plastic drainage pipe, which is widely used in drainage in various scenarios. [0003] The inner wall of the bellows will be washed by sewage and other media, and the sundries in the water will cause the inner wall of ...
