Foaming device and foaming method for degradable cellulose sponge product

Abstract

The invention discloses a foaming device and a foaming method for a degradable cellulose sponge product. The foaming device comprises a foaming box body; an opening is formed in the upper part of the foaming box body; the foaming box body is filled with a foaming sponge mixture; an electric conductor, in contact with the ground, is arranged at the lower bottom of the foaming box body; an electric conductor cover, which can move up and down and is in direct contact with the foaming sponge mixture after moving downwards, is arranged in the opening in the upper part of the foaming box body; the electric conductor cover is connected with an external power supply through a wire; the foaming method comprises the following steps: the foaming box body is filled with the foaming sponge mixture, the electric conductor cover is placed in the foaming box body from the opening of the foaming box body, the electric conductor cover moves downwards to the foaming sponge mixture to be in direct contact with the foaming sponge mixture , and after a transformer is electrified, the current passes through the wire, the electric conductor cover and the foaming sponge mixture in the middle of the foaming box body, and further passes through the electric conductor at the lower bottom of the foaming box body to reach the ground to form a current circuit; when the current passes through the foaming sponge mixture in the middle of the foaming box body, the foaming sponge mixture is heated and coagulated.

Description

technical field [0001] The invention relates to a foaming device and a foaming method of a degradable cellulose sponge product, belonging to the technical field of lignocellulose sponge production technology. Background technique [0002] The existing degradable cellulose sponge products use wood pulp and / or bamboo pulp as the main raw material, and are processed through soaking, pressing, aging, yellowing, making viscose, heating foam molding, and washing. Finally, it is made into sponge products. Among them, the heating and foaming technology basically adopts the steam heating method. This steam heating and foaming technology has a slow heating speed and is only suitable for small-sized sponge foaming, and because of the slow heating speed, the temperature rise is uneven , The viscose material is inconsistent when heated and solidified, which will lead to poor foaming effect. Contents of the invention [0003] The purpose of the present invention is to overcome the defi...
