Description

Technical Field

[0001] This utility model relates to the field of material protection, specifically a polyurea lining spraying equipment. Background Technology

[0002] Polyurea spraying equipment is a high-performance spraying device primarily used for spraying polyurea materials. Polyurea is a 100% solids-content, two-component, fast-curing, on-site spray-applied high-performance material with excellent properties such as wear resistance and corrosion resistance. Polyurea spraying equipment is widely used in waterproofing of high-end building roofs, industrial plants, cold storage facilities, water conservancy projects, bridges, tunnels, underground engineering waterproofing, as well as corrosion protection of power plant demineralization tanks, heavy-duty industrial corrosion protection, and marine corrosion protection.

[0003] Traditional spraying equipment typically mixes the two components only at the spray gun to prevent polymerization due to the rapid reaction of the two components. However, existing technology simply merges them into a single pipe at the spray gun, which may lead to insufficient mixing and affect the spraying effect. Therefore, this invention proposes a polyurea lining spraying equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a polyurea lining spraying device to solve the problems mentioned in the background art.

[0006] Preferably, the spray gun has a feed inlet at its rear end, and the feed inlet is connected to a heating tube.

[0007] Preferably, the spray gun is provided with a mixing chamber, a stirrer is sleeved inside the mixing chamber, and a mixing port is opened on the outside of the stirrer.

[0008] Preferably, an inner stirring blade is fixedly connected to the bottom inner surface of the stirrer, and the inner stirring blade is fixedly connected to the bottom inner surface of the stirrer in a circumferential array.

[0009] Preferably, the spray gun has a spray nozzle at its inner front end.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention improves the mixing efficiency and coating effect by incorporating a mixing device that allows for stirring and mixing of the two-component reactants within the spray gun. Attached Figure Description
