Formula and preparation method of machine-made charcoal binding agent

Abstract

The invention provides a formula and a preparation method of a machine-made charcoal binding agent and belongs to the technical field of clean energy. The machine-made charcoal binding agent comprises a solid part and a liquid part which are combined in parts by mass, wherein the solid part comprises components in parts by mass as follows: 1-6 parts of edible modified corn starch, 0.5-3 parts of food-grade sodium carboxymethylcellulose, 0.2-2 parts of Artemisia argyi peat and 0.1-3 parts of slaked lime; the liquid part contains a guar gum solution with mass concentration being 0.1%-1%. The preparation method comprises steps as follows: preparing the solid part of the binding agent; preparing the liquid part of the binding agent; adding the solid part and the liquid part to powdered carbon in sequence for molding in the preparation process of machine-made charcoal. The adding quantity of the machine-made charcoal binding agent is small, the binding agent has good cold strength and heat stability, the components are all non-toxic and odorless, release of toxic and odorous materials in powdered carbon can be effectively inhibited, and some life cultivation and health preservation effects are achieved; the defect and the problem that current machine-made charcoal is toxic and odorous are effectively solved, and the binding agent has broad application prospect and remarkable social benefit and environment benefit.

Description

technical field [0001] The invention relates to a formula and a preparation method of a machine-made carbon binder, belonging to the technical field of clean energy. Background technique [0002] Binder is the key technology in the production process of machine-made charcoal, and it is also the bottleneck restricting the development of machine-made charcoal. At present, many binders on the market have smoke and smell, poor strength and increase the ash content of machine-made charcoal during the application of machine-made charcoal, which affects the mechanism. Charcoal calorific value. Some binders add chemical substances such as sodium silicate and potassium permanganate to ensure the strength and combustion performance of the machine-made carbon, and there are potential safety hazards. Corn starch uses raw powder, which requires a large amount of use and high cost. [0003] There are not many types of machine-made carbon binders publicly reported in the existing literat...

[0002] Binder is the key technology in the production process of machine-made charcoal, and it is also the bottleneck restricting the development of machine-made charcoal. At present, many binders on the market have smoke and smell, poor strength and increase the ash content of machine-made charcoal during the application of machine-made charcoal, which affects the mechanism. Charcoal calorific value

Some binders add chemical substances such as sodium silicate and potassium permanganate to ensure the strength and combustion performance of the machine-made carbon, and there are potential safety hazards

Corn starch uses raw powder, which requires a large amount of use and high cost

[0003] There are not many types of machine-made carbon binders publicly reported in the existing literature, but there are many kinds of coal binders, mainly concentrated in inorganic binders, organic binders and composite binders. Inorganic binders include Sodium silicate, bentonite, etc. have the advantage of good thermal stability, but the disadvantage is that the increase of ash content affects the calorific value of mechanism charcoal

Organic binders include coal tar, polyvinyl alcohol, sodium humate, etc., which have good cold strength effects, but are expensive and have a pungent taste
