Pre-sulfurizing rubber lining and its production

Abstract

The invention is concerned with a kind of advance vulcanization rubber liner and its produce method. Extrude the rubber piece using for liner through the extruding machine and spread adhesive on the surface of rubber piece and dry. Carry the vulcanization disposal to the rubber piece with vulcanization machine to get the advance vulcanization rubber liner. Stick this rubber liner on surface of metal or pipe directly without using existing method to dispose the liner. It leaves out the vulcanization equipment on locale, reduces the cost and solves the difficult disposal of vulcanization on locale to keep the quality. It also increases the work efficiency by predigesting process and cutting work time limit. The most importance thing is adjusting the vulcanization disposal process to rubber liner and keeps the quality of advance vulcanization rubber liner to fit for the demand of construct.

Description

technical field [0001] The invention relates to a prevulcanized rubber lining and a manufacturing method thereof. Background technique [0002] In the prior art, the vulcanization treatment of the rubber lining usually adopts the following methods: one is the pressurized vulcanization cylinder vulcanization method, that is, the unvulcanized rubber sheet is pasted on the pipe wall, and then put into the pressurized vulcanization cylinder together with the pipeline, and used Vulcanize the rubber lining by means of steam pressurization or hot air pressurization. The second is the atmospheric pressure steam vulcanization method, that is, for large equipment such as tanks and towers that cannot be placed in the vulcanization cylinder, the vulcanization treatment cannot be performed by the pressurized vulcanization cylinder vulcanization method, but after the unvulcanized rubber lining is pasted , blow steam into it, and vulcanize the rubber lining at normal pressure and temperat...

AI Technical Summary

Problems solved by technology

The second is the atmospheric pressure steam vulcanization method, that is, for large equipment such as tanks and towers that cannot be placed in the vulcanization cylinder, the vulcanization treatment cannot be performed by the pressurized vulcanization cylinder vulcanization method, but after the unvulcanized rubber lining is pasted , blow steam into it, and vulcanize the rubber lining at normal pressure and temperature of 80-90°C

It can be seen that the prior art usually needs to vulcanize the rubber lining pasted on various equipment, which is not only difficult to vulcanize, but also difficult to construct on site, time-consuming and laborious, and occupies a lot of land, low work efficiency, and difficult to guarantee quality. Construction process, large investment, etc., therefore, it is absolutely necessary to improve the existing technology
