Problems solved by technology

However, if the gap is narrowed, it is difficult for the raw material slurry to fully enter between the aforementioned plate-shaped protrusions of the papermaking mold when papermaking is used to manufacture the intermediate of the papermaking molded body, that is, the fiber laminate. Some fiber laminates are thin or cannot be pulped
Therefore, it is difficult to manufacture the paper-making molded body in which the spaces between the above-mentioned plate-shaped protrusions are filled.

Embodiment 1

[0172] use Figure 30 The papermaking mold as shown produces a fiber laminate of a papermaking molded body in which the adjacent inner surfaces of the respective plate-shaped protrusions are formed in the shape of a partial conical surface.

[0173]

[0174] According to the ratio of 4 parts of organic fiber (old newspaper), 4 parts of inorganic fiber (carbon fiber), 76 parts of inorganic powder (graphite powder), 12 parts of thermosetting resin (phenolic resin), and 4 parts of thermally expandable particles (each value is mass parts ) are dispersed in water to prepare a slurry having a solid content concentration of about 3% by mass and then make a slurry.

[0175]

[0176] The material of the main body of the pulp mold: aluminum alloy

[0177] The main dimensions of the pulp mould:

[0178] L=288.5(mm)

[0179] W1=13(mm)

[0180] W2=9(mm)

[0181] D=3(mm)

[0182] A1=32.4(mm)

[0183] A2=32.4(mm)

[0184] A3=20(mm)

[0185] d1=0.65(mm)

[0186] d2=0.65(mm)

Abstract

Provided is a paper-making mold (10) including a mold body (10A) and a paper-making net (108) arranged in the paper-making portion of the mold body (10A). The paper-making mold (10) further includes a column-shaped ridge (106) lying on the base face (102) of the paper-making portion, and at least two plate-shaped ridges (105) formed at a predetermined spacing at predetermined positions of the longitudinal direction of the column-shaped ridge (106) such that the adjoining inner face portions (105A) of the plate-shaped ridges (105) are formed of a portion of a circular cone or a hyperboloid.

Description

technical field [0001] The invention relates to a pulp-making mold and a pulp-making molded body. Background technique [0002] As a method for producing a papermaking molded article, the applicant has already proposed the technique described in Patent Document 1 below. In this technique, a fiber laminate is prepared from a raw material slurry containing fiber materials such as inorganic fibers or organic fibers, dehydrated, dried and molded to produce a paper-made molded body having a desired molding surface. [0003] In Patent Document 1 figure 1 discloses the following pulp-making mold, which has a horizontal semi-cylindrical columnar convex portion on the base surface of the pulp-making surface, and is formed at predetermined intervals at predetermined positions in the longitudinal direction of the columnar convex portion. Two semi-cylindrical plate-shaped protrusions. [0004] In using this papermaking mold to make papermaking Patent Document 1 Figure 8 In the case...
