Abstract
The invention relates to a gypsum board capable of being bent at will and a preparation method thereof. The gypsum board which can be bent at will after soaking in water for two or three minutes when in use. A method of making a gypsum board that can be bent at will, comprising the steps of: (1) shredding wood pulp fiber, soaking and pulping; (2) Adding water and additives into the calcined gypsum to obtain dihydrate gypsum slurry; (3) Adding the treated wood pulp into the gypsum slurry in proportion; (4) The gypsum board which can be bent at will is manufactured by molding (generally using two molding modes of a shoveling method and a pulp flowing method) and (5) steam curing.
Description
Technical Field
The invention relates to a gypsum board capable of being bent at will and a preparation method thereof.
Background
The gypsum board is a material made from building gypsum as a main raw material. The light-weight building material is light in weight, high in strength, thin in thickness, convenient to process, good in sound insulation, heat insulation, fire resistance and the like, and is one of the novel light-weight boards which are developed seriously at present.
Gypsum boards have been widely used for interior partition walls, wall cladding panels (instead of wall plastering), ceilings, sound absorbing boards, floor base boards, various decorative boards, and the like of various buildings such as houses, office buildings, shops, hotels, industrial workshops, and the like.
In addition, the use of gypsum products is expanding, and in addition to being used as a base liner, as a surface finishing material, even as floor tiles, exterior wall substrates, wall cores, and the like.
At present, gypsum boards produced in China can only be used as a flat board. If a curved, circular arc shape is encountered in the decoration. Irregular surfaces such as waves. Can only be realized by means of plaster mold.
When the gypsum board capable of being bent at will is used, the gypsum board can be soaked in water for two to three minutes to form a bent shape at will, and the gypsum board is shaped after being dried.
A method of making a gypsum board that can be bent at will, comprising the steps of:
(1) Shredding wood pulp fiber, soaking and pulping;
(2) Adding water and additives into the calcined gypsum to obtain dihydrate gypsum slurry;
(3) Adding the treated wood pulp into the gypsum slurry in proportion;
(4) Through molding (generally using two molding modes of a shoveling method and a pulp flowing method);
(5) Steam curing to form the gypsum board which can be bent at will.
Disclosure of Invention
The invention aims to provide a gypsum board which can be bent at will.
It is another object of the present invention to provide a method of making gypsum board that can be bent at will.
In order to solve the technical problems, the invention provides the following technical scheme:
when the gypsum board capable of being bent at will is used, the gypsum board can be soaked in water for two to three minutes to form a bent shape at will, and the gypsum board is shaped after being dried.
A method of making a gypsum board that can be bent at will, comprising the steps of:
(1) Shredding wood pulp fiber, soaking and pulping;
(2) Adding water and additives into the calcined gypsum to obtain dihydrate gypsum slurry;
(3) Adding the treated wood pulp into the gypsum slurry in proportion;
(4) Through molding (generally using two molding modes of a shoveling method and a pulp flowing method);
(5) Steam curing to form the gypsum board which can be bent at will.
Detailed description of the preferred embodiments
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and explanation only and is not intended to limit the present invention.
The invention can adopt cotton fiber, fibrilia, wood fiber, bamboo fiber and the like as plant fibers.
Example 1
In the production of the gypsum board formulation which can be bent arbitrarily, 8% wood pulp fiber is added;
then producing gypsum board which can be bent at will according to the normal production flow;
example 2
In the production of the randomly bendable gypsum board formulation, 10% wood pulp fiber is added;
then producing gypsum board which can be bent at will according to the normal production flow;
example 3
In the production of the gypsum board formulation which can be bent arbitrarily, 8% wood pulp fiber is added;
and adding a water reducing agent, a retarder, a reinforcing agent and the like into the slurry.
The arbitrarily bendable gypsum board is then produced in accordance with normal production procedures.
