Application characteristics of dishwasher special drying agent
时间:2019-05-17 来源:
At present, automatic dishwashers are not popular in Chinese families, but they are widely used in public places such as hotels, restaurants, fast food restaurants and factory canteens。Different automatic dishwashers have different washing cycles, each consisting of a combination of steps such as soaking or pre-washing, main washing, rinsing, sterilization and drying。So dishwashers were born for this purpose。Dryer for dishwashersIt is a chemical daily product, especially a drier。
Many surfactants are used in rinsing AIDS (i.e. dryers)。Dryer for dishwashersIts main function is to reduce the surface energy of the vessel or reduce the interfacial tension between liquid and solid。Thus, the rinsing solution can flow rapidly from the surface of the vessel to be washed in a uniform thin curtain of water, so that the spots and spot films on the vessel can be minimized and the drying of the vessel can be accelerated。In general, foam is the enemy of the rinsing process。Because the first foam will reduce the effect of rinsing AIDS;Second, sometimes it will overflow the machine and affect the normal operation of the machine。Therefore, low-foam surfactants or surfactants with defoaming properties are most suitable for rinsing AIDS。
The main component of dishwasher drier is surfactant, which is generally composed of a variety of surfactants. Reducing the turbidity point or water solubility of the surfactant may help to enhance its adsorption trend on the surface of the tableware and speed up its adsorption rate, but it will bring other adverse effects。If the turbidity point is too low, the product will encounter great difficulties in preparation, such as the need to use additional water-soluble growth additives, which will significantly increase the cost。
