Embodiment Construction

[0017] See Table 1 for the formula components and proportioning ratio of the embodiment and its dust suppression performance.

[0018] The preparation method of the embodiment: the solid formula components are formulated into the following aqueous solutions, mixed according to the mass content ratio of each component when used, and glycerin is added, stirred evenly, and the product is obtained.

[0019] (1) Sodium polyacrylate is prepared into a 0.12% solution, and sodium polyacrylate is added to the measured water with a high-speed stirring device, stirred at room temperature for 3 to 4 hours, until a uniform transparent liquid is set aside;

[0020] (2) Hydroxyethyl cellulose is made into a 2% solution, and carboxymethyl cellulose is added to the measured water with a high-speed stirring device, and stirred at room temperature for 3 to 4 hours until it becomes a uniform transparent liquid. Store at low temperature for later use;

[0021] (3) Make a 6% solution of polyethyle...

Abstract

The invention relates to a compound chemical dust suppressant as well as a preparation method and an application thereof. The compound chemical dust suppressant is characterized by comprising the following components in percentage by mass according to the formula: 0.01-0.03% of sodium polyacrylate, 0.04-0.09% of hydroxyethyl cellulose, 0.5-1.5% of polyethylene glycol 4000, 1.0-2.5% of glycerin and the balance of water. The preparation method comprises the following steps of: firstly, respectively preparing all the components into aqueous solutions, and then, mixing all the components according to the mass proportions. The compound chemical dust suppressant is good in dust suppressing effect, wide in raw material source, simple in operation, high in performance cost ratio, free of toxicity and corrosion, easy to degrade under a natural condition, free of secondary pollution and suitable for popularization for dust prevention in mine tailing pond regions and road transportation dry beach regions thereof.

Description

technical field [0001] The invention relates to a chemical dust suppressant in the field of mineral dust control, in particular to a compound chemical dust suppressant and its preparation method and application. Background technique [0002] In recent years, the technology of chemical dust suppression has been developed rapidly abroad, especially in the past 30 years, with the continuous deepening of research on chemical dust suppression technology, foreign countries have begun to apply surfactants to dust suppression technology in mining , with the improvement of people's environmental awareness and the development of the modern chemical industry, the depth and breadth of research on chemical dust suppressants has also expanded rapidly. Many countries have made many achievements in the research of coal dust inhibitors. The representative ones are the DCL-1803 bonded chemical dust suppressant and Conherex bonded chemical dust suppressant developed in the United States, and t...
