Problems solved by technology

But at present there is not a kind of craft that can make salt into handicrafts. Therefore, using salt as raw material to develop handicraft-type salt can not only be used as souvenirs for special tourism in salt areas, but also increase the variety of salt and improve the economic benefits of enterprises; And there is no mold for suppressing this kind of handicraft type salt at present

Embodiment 1

[0033] Embodiment 1: a kind of preparation method of handicraft type salt is characterized in that it is made of following steps:

[0034] ① Preparation of raw materials: select coarse-grain refined salt and fine-grain refined salt, and mix them evenly at a mass ratio of 8:2;

[0035] ②Dry the mixture of refined salt prepared in step ① so that the water content is 0.22%, put it into the mold, 2 Hold the pressure for 2min under the pressure and carry out the compression molding treatment.

[0036] 3. The refined salt pressed and formed in step 2. is demoulded;

[0037] ④ After routine product inspection and packaging, it is a finished product.

[0038] The coarse refined salt described in the above-mentioned steps 1. is the salt grain that average particle diameter is 0.2mm, and said fine granular refined salt average particle diameter is the salt grain of 0.075mm.

[0039] The compacted density of the refined salt after the compression molding described in above-mentioned s...

Abstract

A manufacturing method for a handicraft article salt includes the steps: (1) preparing materials; (2) drying and pressing the materials to form; (3) demoulding; (4) checking product; (5) packaging, namely finished product. A die for the handicraft article salt includes an upper convex die, an upper concave, a lower concave die and a lower convex die. The invention has the advantages of : (1) selecting refined salt as the material and the material section is novel, easily acquired and cheap; (2) selecting a press forming method and the manufacturing method is safe, energy-saving and protecting environment; (3) increasing the variety of salt products and improving the economic benefits of enterprises; the invention also has the advantages that: (4) the concave die is divided into the upper part and the lower part, thus being not only convenient for the processing of the inner surface of the concave die, but also being convenient for the product for press forming to be gotten out from the concave die; (5) the lower convex die is curved with a forming surface cooperated with the lower concave die to form a forming chamber and the lower concave die also plays the role of pushing the product out of the lower concave die to lead the image to be clear with no damage; (6) the lower convex die and the lower concave die are combined to simplify the structure of the lower concave die and the processing of the image is convenient; (7) the invention has simple producing technique and low cost, which contains no additive and no peculiar smell.

Description

(1) Technical field: [0001] The invention relates to a manufacturing method and a mold of a refined salt product, in particular to a manufacturing method of handicraft type salt and a mold for pressing and molding thereof. (two) background technology: [0002] "Type salt" is a general term for pressing loose salt particles into a block-shaped product with a certain shape and strength according to different purposes. [0003] Type salt has a variety of unique functions and can meet special requirements in many aspects. For example, various trace elements can be added to it to make salt bricks for animals to lick, supplement inorganic salts and trace elements; it can also be used as an energy-saving boiler to soften Regenerant of ion exchange resin for water treatment, etc. [0004] my country's salt industry has a long history. In recent years, salt areas such as seas, lakes, wells, and mines have developed characteristic tourism in combination with local characteristics. B...
