Description

Technical Field

[0001] The invention relates to the technical field of zinc chloride regeneration, in particular to a preparation device for zinc chloride regeneration for vulcanized fiber and a production process thereof. Background Art

[0002] In the production process of vulcanized fiber paper, zinc chloride plays an extremely critical role. Zinc chloride solution is widely used as an impregnating agent for vulcanized fiber production. It can effectively cause a series of complex chemical and physical changes such as swelling, dissolution and regeneration of cellulose fibers, thereby giving vulcanized fibers unique properties, such as higher strength, toughness and certain corrosion resistance. Every ton of vulcanized fiber paper produced consumes about 8% of zinc chloride raw materials. In the original process, a very small part of the 8% of raw and auxiliary materials consumed is taken away by paper products and consumed naturally, but most of them are lost to the production wastewater system with a large amount of clean water through the desalination process. In the long run, it has caused great economic losses to the company. In order to solve this problem, a preparation device for the regeneration of zinc chloride for vulcanized fiber is designed.
