Polymerization reaction kettle for polyacrylamide production

Abstract

The invention relates to a polymerization reaction kettle for polyacrylamide production, which comprises a reaction kettle body, an elastic friction ring is arranged in the reaction kettle body, and the elastic friction ring is slidably arranged on a first slide bar and a second slide bar through a first magnetic control slide block and a second magnetic control slide block; the second magnetic control slide block and the first magnetic control slide block are provided with an outer magnetic control device in a matched manner, and the outer magnetic control device is arranged outside the reaction kettle body.

Description

technical field [0001] The invention relates to the technical field of a polymerization reactor for polyacrylamide production, in particular to a polymerization reactor for polyacrylamide production. Background technique [0002] The polymerization kettle is a reaction vessel for polymer polymerization to produce artificial latex. The reaction monomers undergo polymerization in the polymerization kettle to form long chains. The (carboxy) styrene-butadiene latex has a certain viscosity and is easy to stick to the inner wall of the polymerization kettle. Wall hanging phenomenon; if it is not removed in time and sticks to the inner wall of the polymerization kettle, it will have an adverse effect on the reaction, and at the same time, it will have an adverse effect on the reaction of the next reactor, and it is difficult to control the consistency of the product. Cutting is difficult. [0003] The traditional treatment method is to spray Teflon material on the inner surface of...

[0002] The polymerization kettle is a reaction vessel for polymer polymerization to produce artificial latex. The reaction monomers undergo polymerization in the polymerization kettle to form long chains. The (carboxy) styrene-butadiene latex has a certain viscosity and is easy to stick to the inner wall of the polymerization kettle. Wall hanging phenomenon; if it is not removed in time and sticks to the inner wall of the polymerization kettle, it will have an adverse effect on the reaction, and at the same time, it will have an adverse effect on the reaction of the next reactor, and it is difficult to control the consistency of the product. Cutting difficulty

[0003] The traditional treatment method is to spray Teflon material on the inner surface of the polymerization kettle, but in the process of repeated use, the sprayed material on the inner surface will fall off, and it must be re-sprayed every once in a while, resulting in repetition, troublesome operation, and greatly increasing the cost of use , and the shedding of the sprayed material on the inner surface during use will affect the product quality; the cleaning effect of the oil spray method is not ideal, the wall removal rate is low, and there are many damaged raw materials; the long-term wall condensation will cause the inner wall to decay and damage; Polymerization Reactor for Polyacrylamide Production
