A kind of composite liquid absorbing material papermaking, composite processing technology and equipment

Abstract

The invention discloses a papermaking and composite processing technology of a composite liquid-absorbing material, including papermaking on the composite layer, papermaking under the composite layer, compounding, and rewinding processing; the invention also discloses a composite liquid-absorbing material. Composite processing equipment, including the first cylinder forming mechanism, the second cylinder forming mechanism, the drying cylinder drying mechanism, the composite drying cylinder drying mechanism and the new adjustable tension rewinding mechanism, the first cylinder forming mechanism and the second cylinder forming mechanism The mechanism is symmetrically arranged and rotates in opposite directions; a pressing compounding mechanism is installed directly under the drying mechanism of the compound drying cylinder, and a powder powder mechanism is installed under the pressing compounding mechanism; the process for adding the polymer water-absorbing resin in the present invention is simple and easy to operate, and the total amount of addition is easy to control ;Improve the water absorption speed, water locking performance and comfort of the liquid absorbing material; the water absorption rate is increased to more than 50 times, and the expansion width can be adjusted according to the demand; continuous production is realized; the dusting process is uniform.

Description

technical field [0001] The invention relates to a papermaking and composite processing technology and equipment, in particular to a papermaking, composite processing technology and equipment of a composite liquid-absorbing material, belonging to the technical field of liquid-absorbing materials. Background technique [0002] Composite absorbent materials are extremely useful for making absorbent articles capable of absorbing fluid and retaining lotion. Such as women's sanitary napkins in sanitary and medical products, diapers, disposable diapers, preservatives for agriculture, forestry and vegetable moisture preservation, it can also be used as sanitary pads, such as pads for nursing mothers, children's beds Pads, mattresses for incontinent patients, hemorrhoid patients and surgical pads. [0003] At present, the composite liquid-absorbing materials on the market generally have a three-layer structure, that is, a surface layer, a core layer, and a bottom layer, and the core...

AI Technical Summary

Problems solved by technology

[0010] (1) The process operation when adding polymer water-absorbing resin is not easy, which is not conducive to controlling the total amount of polymer water-absorbing resin;

[0011] (2) Liquid-absorbing materials have slow water absorption speed, poor water-locking performance, poor softness, and poor comfort;

[0012] (3) The water absorption rate of the liquid-absorbent material needs to be improved, and the expansion width is not easy to adjust according to the demand;

[0013] (4) The processing equipment for liquid-absorbing materials cannot achieve continuous production, the production efficiency needs to be improved, and there are many paper breaks, resulting in unstable final product quality;

[0014] (5) The material spreading device for polymer water-absorbent resin, the material spreading process is likely to cause uneven thickness of the polymer particle layer, thick in the middle and thin on both sides, which affects the composite effect
