Problems solved by technology

[0003] However, the current sandware is only suitable for cooking methods such as boiling, stewing, and steaming. These cooking methods are protected by a large amount of soup water, and the pot is heated more evenly and the temperature difference is small. Therefore, the thermal stability of the pot is relatively strict. Be looser. If you need to use frying, frying, deep-frying and other heating methods with high temperature, rapid fire, and large temperature difference, the existing cooking utensils made of sandware are very prone to bursting.
In addition, if the size of the product is large, it is not easy to produce and process

Embodiment 1

[0020] A kind of black sand device described in the present embodiment is made from the following raw materials in parts by weight: 60 parts of Baishan mud, 40 parts of independent carbon secondary coal, and the mass percentage of iron in the described Baishan mud is 3 -5%, the raw material is obtained after the steps of mining, weathering, drying, crushing and drying.

[0021] Its preparation method comprises the following steps:

[0022] (1) Mud making: Add 5 times of water to the raw material, ball mill, sieve, and stale in a dark room for 18 days, and then enter the forming step after vacuum refining mud. Mesh sieve, control the plasticity index of mud ≥ 3;

[0023] (2) Forming: The mud is formed by hand, machine or grouting;

[0024] (3) Drying the billet: the formed black sand device blank tire is placed in a cool and ventilated place at 15°C to dry, avoiding direct sunlight;

[0025] (4) Decoration: Carry out appropriate engraving decoration on the dried black sandwa...

Abstract

The invention discloses a black sand vessel and a preparation method thereof. The black sand vessel is made of the following raw materials in parts by weight: 50-80 parts of Baishan mud, 20-50 parts of independent carbon secondary coal; The mass percentage of iron in Shanni is 3-5%. Through the steps of mud making, molding, drying, firing, glaze extraction, and furnace, the obtained black sand ware has a unique black luster, does not oxidize, does not change color, The texture is strong, and it has been verified by experiments that it has higher thermal stability, high temperature resistance, corrosion resistance, and is harmless to the human body. It is very suitable for daily cooking food.

Description

technical field [0001] The invention relates to the technical field of sand ware and production technology, in particular to a black sand ware and a preparation method thereof. Background technique [0002] The cooking utensils made of sandware are very popular in the common people and the catering industry because of their unique advantages such as good heat storage, environmental protection, and corrosion resistance. For example, the casserole series that appeared on the market are very popular among people. [0003] However, the current sandware is only suitable for cooking methods such as boiling, stewing, and steaming. These cooking methods are protected by a large amount of soup water, and the pot is heated more evenly and the temperature difference is small. Therefore, the thermal stability of the pot is relatively strict. Looser, if it is necessary to adopt high temperature, rapid fire, and large temperature difference heating methods such as frying, frying, and fryi...
