Problems solved by technology

In industrial production, the longer the time is, the more serious the fouling will be. First, it will block the pipeline and reduce the flow rate. Second, it will damage the equipment, shorten the service life of the container, interfere with normal production, and bring great distress and trouble to people.
At present, the softening of hard water is basically handled by a hard water softening device composed of a resin exchanger, but this kind of device requires a lot of investment, low efficiency, troublesome maintenance, and high cost, so it is difficult to popularize and use it in actual production.

Abstract

The invention discloses an alkaline hard water softener. The alkaline hard water softener comprises the following raw materials by mass percent: 15-30% of sodium ethylene diamine tetracetate, 5-20% ofbenzisothiazolone, 0.5-8% of phosphonyl butane tricarboxylic acid and the suitable amount of pure water. The use of the alkaline hard water softener is convenient, the preparation is simple, the costis lower, a special hard water softening system is not needed, the hard water softening effect is good, and the hardness in the water is effectively reduced. While the tap water is circularly used, scale is not formed in a container and a pipe. The bactericidal performance is excellent, and microorganisms are avoided from generating in the circularly used water, so the water resource is effectively saved, and a device is protected.

Description

technical field [0001] The present invention relates to an alkaline hard water softener for softening hard water. Background technique [0002] Hard water will cause great harm in industrial production and life. When these hard water is heated or boiled through pipes, containers, boilers, etc., the calcium, magnesium, and iron ions in the hard water will destabilize, decompose, overflow from the water, stick Knot on the inner wall of pipes and containers. The more particles in the water, the harder the water and the more scale will be formed. In industrial production, the longer the time is, the more serious the fouling will be. First, it will block the pipeline and reduce the flow rate. Second, it will damage the equipment, shorten the service life of the container, interfere with normal production, and bring great distress and trouble to people. At present, the softening of hard water is basically handled by a hard water softening device composed of a resin exchanger, bu...
