Embodiment 1

[0048] Example 1 A kind of papermaking and composite processing technology of composite liquid-absorbent material

[0049] Such as figure 1 As shown, the papermaking and composite processing technology of a composite liquid-absorbing material provided by the present invention specifically includes the following steps:

[0050] 1. Manufacture of the upper and lower paper of the composite layer:

[0051] (1) Papermaking on the composite layer:

[0052] 1) The pulp is beaten and batched according to the process requirements, and the pulp concentration in the forecaster pool is 2.5-3.5%;

[0053] 2) The pulp concentration obtained in step 1) is adjusted to 1% by the concentration control system, and then pumped into the pulping box, and a stripping agent is added in the pulping box. The stripping agent is an alcohol stripping agent, and the dosage is 1-3kg / ton of pulp ;

[0054] 3) Pump the slurry adjusted in step 2) into the mixing box. During the pumping process, adjust the ...

Abstract

The invention discloses a papermaking and composite processing technology of a composite liquid absorbing material. The technology comprises the steps of composite layer upper paper papermaking, composite layer lower paper papermaking, compounding and rewinding processing. The invention further discloses papermaking and composite processing equipment for the composite liquid absorbing material, the papermaking and composite processing equipment comprises a first rotary screen forming mechanism, a second rotary screen forming mechanism, a drying cylinder drying mechanism, a composite drying cylinder drying mechanism and a novel adjustable tension rewinding mechanism, and the first rotary screen forming mechanism and the second rotary screen forming mechanism are symmetrically arranged and are opposite in rotating direction; a squeezing composite mechanism is installed under the composite drying cylinder drying mechanism, and a powder scattering mechanism is installed under the squeezingcomposite mechanism; the process for adding the high-molecular water-absorbent resin is simple and convenient to operate, and the total adding amount is easy to control; the water absorption speed, the water locking performance and the comfort level of the liquid absorption material are improved; the water absorption rate is increased to 50 times or above, and the diffusion and permeation width can be adjusted as required; continuous production is realized; and powder spraying process is uniform.

Description

technical field [0001] The invention relates to a papermaking and composite processing technology and equipment, in particular to a papermaking and composite processing technology and equipment for composite liquid-absorbing materials, and belongs to the technical field of liquid-absorbing materials. Background technique [0002] Composite absorbent materials are extremely useful in the preparation of absorbent articles which absorb fluids and retain washing fluids. Such as women's sanitary napkins, paper diapers, disposable diapers in sanitary and medical supplies, fresh-keeping agents and vegetable moisture preservation agents for agriculture and forestry, it can also be used as sanitary liners, such as breastfeeding liners, and children's beds Pads, mattresses for incontinent patients, hemorrhoid patients and surgical pads. [0003] Composite liquid-absorbent materials currently on the market generally have a three-layer structure, namely the surface layer, core layer, a...
