Steel-liner plastic container and processing process thereof

Abstract

The invention relates to a steel-liner plastic container and a processing process thereof. The steel-liner plastic container comprises a container body and an antiseptic plastic liner adhered to the container body, and is characterized in that a filling space is reserved between the inner wall of the container body and the antiseptic plastic liner and internally provided with an adhesive for adhering the antiseptic plastic liner and the container body. By adopting the technical scheme, the invention provides the antiseptic steel-liner plastic container and the gap-resistant processing process of the steel-liner plastic container for avoiding generating an internal gap.

Description

technical field [0001] The invention relates to a steel-lined plastic container and its processing technology. Background technique [0002] At present, the inner wall of the container used to store chemical media in the market and information is extremely vulnerable to corrosion damage, and usually technicians in this field use anti-corrosion plastics as the lining of the container. [0003] Anti-corrosion plastic lining is widely used in various industries as an effective anti-corrosion measure for pipelines and containers. The usual practice is to completely cover the main body with the anti-corrosion plastic lining to form anti-corrosion protection. Since the anti-corrosion plastic lining and the lined surface cannot be exactly the same in shape, a space is generated between the lined surface and the anti-corrosion plastic liner. In addition, the thermal expansion coefficient of the container body and the anti-corrosion plastic lining may be very different, so under th...

AI Technical Summary

Problems solved by technology

In addition, the thermal expansion coefficient of the container body and the anti-corrosion plastic lining may be very different, so under the influence of factors such as the weight, temperature, pressure, flow, impact (especially negative pressure, high temperature) of the internal medium, the anti-corrosion plastic lining will Deformation, bulging, deflation, cracking, falling off, making the lining invalid

[0004] In order to eliminate the above drawbacks, those skilled in the art usually paste the anti-corrosion plastic lining on the container body, or fill the space between the lined surface and the anti-corrosion plastic liner with resin, but after the construction, the container body and the anti-corrosion plastic liner will still remain. voids, and the filled resin is also voided and brittle, causing the liner to fail
