Dry method papermaking method and system for anhydrous micro-electricity papermaking plant fiber

Abstract

The invention discloses a dry method papermaking method for an anhydrous micro-electricity papermaking plant fiber. By means of micro-static-electricity papermaking fiber forming, air carrying the single papermaking fiber is sent into a high-voltage direct-current electric field, the single papermaking fiber can carry negative charges through corona discharge of a discharge negative electrode, the single papermaking fiber with the negative charges moves to a positive plate in an oriented mode, and finally a papermaking fiber net is formed on the positive plate through discharge sedimentation; furthermore, spraying and humidifying are conducted on the single papermaking fiber, and therefore the fiber can carry water mist drops, and therefore the electric conductivity of the single papermaking fiber is greatly improved. Extrusion compaction and dewatering drying are conducted on paper webs through a thermal roll-in device, and normal operation of the subsequent processing procedure is easily conducted; in conclusion, the papermaking fiber forming speed and quality in the dry method forming process are increased, no sewage can be produced, water resources are saved, and the environment is protected. The invention further discloses a dry method papermaking system for the anhydrous micro-electricity papermaking plant fiber.

Description

technical field [0001] The invention relates to the technical field of dry-process papermaking, in particular to a dry-process papermaking method and system for producing plant fibers by anhydrous microelectricity. Background technique [0002] Papermaking is divided into traditional wet papermaking and dry papermaking. Dry papermaking is a relatively advanced and cutting-edge papermaking method today. Its general principle is: use air as the carrier of papermaking fibers, form a thin layer of fibers on the forming wire, and then use adhesives to bond them into paper. Papermaking method. It differs from the traditional wet-laid papermaking method in that the fibers are formed into the web without water. Since the appearance, performance and use of the finished product are all between paper and fabric (cloth), it can have the appearance similar to paper and the performance and feel similar to cloth according to needs, and it has more characteristics in application, so the t...

Problems solved by technology

With the development of economy and the progress of science and technology, the papermaking fiber web obtained by the air dry forming process has improved in the forming speed and forming quality (for example: the orderly arrangement of the papermaking fibers, the connection strength between the papermaking fibers, the radial direction of the papermaking fiber web, etc.) The uniformity of the thickness, etc.) is more and more unable to meet the actual needs
