Abstract
The invention discloses a dust-removing modifying agent capable of efficiently capturing, adsorbing and removing smoke dust. The modifying agent is prepared from the following components in percent by weight: 15-25% of secondary-alkyl sodium sulfate, 30-35% of hydroxy synthetic alcohol polyoxyethylene ether, 8-15% of dimethyl dodecyl amine oxide, 10-20% of alkyl polyglycoside, 10-15% of anhydrous potassium aluminum sulfate and 5-15% of fatty alcohol-polyoxyethylene ether. According to the dust-removing modifying agent, the surface acting force can be reduced to be a quarter of that of common substances; the surface wet strength and the capturing and adsorption capability are improved; hydrophilic groups on the surfaces of the substances can be efficiently combined with dust grains in the smoke dust, so that the hydrophilic groups can be rapidly wetted, covered, adsorbed and settled; and the viscidity of molecule surfaces can be improved so that the smoke dust is stuck when being in contact with the surface of liquid, and is not easy to separate from liquid components at a high temperature, and furthermore, smoke dust molecules are prevented from escaping after being adsorbed. The dust-removing modifying agent is environmentally friendly, has the very high stability under strong-alkali and strong-acid environments and weak-acid and weak-alkali environments, and is applicable to various working conditions.
