Description

ABS condensation dehydration vacuum filter

Technical Field

The utility model relates to an energy, chemical industry equipment technical field especially relate to an ABS condensation dehydration vacuum filter.

Background

The ABS resin is graft copolymer of acrylonitrile, 1, 3-butadiene and styrene, and the production method is basically mixture of graft copolymer of butadiene and acrylonitrile-styrene copolymer. ABS is the polymer with the largest output and the most extensive application at present, organically combines various performances of polybutadiene, polyacrylonitrile and polystyrene, and has excellent mechanical properties of hardness, toughness and rigidity balance. With the improvement and promotion of the process method, the ABS resin has strong competitive advantages in a plurality of fields such as automobiles, electronics, electrics, plastic alloys and the like.

ABS resins have been developed on the basis of the modification of polystyrene resins. The ABS production process is roughly divided into six categories: blending (which is currently eliminated), emulsion graft polymerization (which is currently replaced by emulsion graft SAN blending), emulsion graft SAN blending (which includes emulsion graft-emulsion SAN blending, emulsion graft-suspension SAN blending, emulsion graft-bulk SAN blending), continuous bulk polymerization, bulk-suspension polymerization, and emulsion-bulk polymerization. The main method for producing the ABS resin at present comprises the following steps: emulsion graft-bulk SAN blending processes and continuous bulk polymerization processes.

The continuous bulk polymerization method has the advantages that firstly, the process flow is short, and only one set of bulk polymerization device is needed; secondly, the operation is easy, the pollution is less and the investment is saved. However, due to the limitations of the bulk process, ABS with a rubber content of more than 20% cannot be produced, the impact strength of the product is limited, the control of the rubber particle size is relatively difficult, and the high gloss that can be achieved by the emulsion graft-bulk SAN blend method cannot be achieved, so that the type and properties of the product are limited to some extent and need to be further improved and enhanced. Thus, continuous bulk processes currently produce a smaller variety of products.

The emulsion graft-bulk SAN blending process is the most predominant ABS production process at present. The emulsion grafting-bulk SAN blending method mainly comprises the following steps: the process flow of the polybutadiene latex for grafting synthesis, the polybutadiene latex graft polymerization, the bulk SAN particle manufacture, and the graft latex and SAN blended into ABS resin is shown in figure 1.

With the increasing demand of ABS and the high-demand comprehensive economic performance, the industrial production has higher and higher requirements on process equipment. Therefore, energy-saving, environment-friendly and high-efficiency multifunctional equipment has become the current mainstream, and the traditional ABS agglomeration dehydration filter gradually does not meet the requirements of the current equipment.
