Strip-shaped slow-release scale inhibitor and preparation method thereof

Abstract

The invention discloses a strip-shaped slow-release scale inhibitor. The strip-shaped slow-release scale inhibitor is prepared from the following components in percentage by weight: 40% to 60% of scale inhibitor, 10% to 30% of adhesive, and 20% to 40% of water. In addition, the invention also discloses a preparation method of the strip-shaped slow-release scale inhibitor. The preparation method comprises the following steps of (1) fully stirring the scale inhibitor, the adhesive and the water, so as to form a uniform plastomer; (2) extruding and forming the plastomer in step (1), so as to obtain a wet material of the strip-shaped slow-release scale inhibitor; (3) drying the wet material of the strip-shaped slow-release scale inhibitor in step (2), so as to obtain the strip-shaped slow-release scale inhibitor. The strip-shaped slow-release scale inhibitor has the advantages that the preparation method is simple, the mechanical strength is high, and the lasting scale inhibiting effect is realized.

Description

technical field [0001] The invention relates to a strip-shaped slow-release scale inhibitor and a preparation method thereof, belonging to the technical field of water treatment. Background technique [0002] The tap water used in cities is mainly in the form of groundwater, which contains more minerals, especially calcium and magnesium ions. The hardness of water is mainly composed of cations, such as calcium ions and magnesium ions. If the hardness of water is too high, it will not only make the soap not easy to foam and reduce the decontamination ability, but also cause the clothes to harden and Hard and brittle, shortening the service life of clothes. However, if you make tea with hard water, the aroma of the tea will be low, the soup will be dark, and the taste will be poor. In addition, if the hardness of water is too high, it is easy to cause scaling on the pipeline or inner wall surface of wading household appliances, which not only affects the use effect and life ...

Problems solved by technology

Among them, the ion exchange technology has the advantages of simple method, obvious effect, and high removal rate, but its disadvantages are that the ion exchange resin is easily polluted and oxidized to cause failure, the regeneration operation is complicated, and sodium ions will be replaced, making this type of water unsuitable for long-term use. drink

Membrane separation technologies commonly include nanofiltration membrane (NF) and reverse osmosis membrane (RO) technologies. The characteristics of these two technologies are that the effect is obvious and stable, but they have higher requirements on the inlet water pressure and the water utilization rate is low. , Membrane plugging is prone to occur in areas with high hardness water quality

Although the silicon-phosphorus crystal technology is effective, its scale inhibition performance is unstable, sometimes good and sometimes bad, and the water flow needs to keep flowing to have the scale inhibition effect. When the water flow is still for a certain period of time, the phosphorus content in the water will increase rapidly

Chelating resin fiber technology, its anti-scaling principle is similar to ion exchange resin, but has the defects of short life and fast saturation

In addition, the latest research has shown that adding scale-inhibiting materials to activated carbon filter elements can achieve scale-inhibiting effects by interfering with the formation of scale nuclei and lattices. However, the scale-inhibiting materials on the surface of activated carbon are easy to lose and saturate quickly, so they cannot achieve long-lasting Anti-scaling effect
