Embodiment Construction

[0012] The present invention will be further described in detail below in combination with specific embodiments.

[0013] A process for forming an absorbent body, comprising the following steps:

[0014] In the first step, the raw material is crushed, and the crushed slurry is input into the die wheel;

[0015] In the second step, the polymer material is added when the pulverized slurry is input into the mold wheel, and the formula liquid is sprayed on one side when the polymer material is added, so that the surface of the polymer material forms a gel by spraying, So that the slurry and the polymer can be bonded;

[0016] In the third step, the polymer material and slurry are input into the mold cavity of the mold wheel for molding.

[0017] The polymer material contains strong hydrophilic groups, and the strong hydrophilic groups are a mixture of phthalamide groups, shuttle groups, and sulfonic acid groups, and the mixing ratio is 2:1:2.

[0018] The formula liquid is a mi...

Abstract

The invention relates to the field of disposable hygiene products, and particularly an absorber forming process. The absorber forming process comprises the following steps of firstly smashing raw material, and inputting smashed slurry in a die wheel; and secondly adding high-molecular material when the smashed slurry is input in the die material, spraying a formula liquid at one side when the high-molecular material is added, and forming gel on the surface of the high-molecular material through spraying so as to make the slurry agglutinate with the high-molecular material; and inputting the high-molecular material and the slurry into die cavities of the die wheel to form.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to an absorber forming process. Background technique [0002] In the traditional manufacturing process, the absorber is not dense, and the phenomenon of polymer and wood pulp fibers moving in series during the secondary production process of the absorber has become a common factor affecting the absorption performance and thickness of the product. In recent years, thin absorbers have become popular in the market, and the mixing ratio of wood pulp fibers and polymers has reached 1:1. The macromolecules in this kind of thin absorber are not easy to be wrapped by wood pulp fibers, and the macromolecules move in series, which is easy to agglomerate, and the core body is easy to break after fully absorbing the liquid. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an absorber forming process that can effectively e...
