Example Embodiment

[0020] Example 1

[0021] Mix 240 mg of modified sodium polyaspartate, 54 mg of sodium gluconate and 6 mg of zinc sulfate to obtain the water treatment agent of the present invention. Place it in 1 liter of water and stir evenly. The pre-membrane treatment is 48 hours, and the pre-membrane concentration is It is 300ppm, and it is diluted to the normal treatment concentration (10-100ppm) according to the water quality to be treated, and the water treatment agent with the normal treatment concentration is obtained.

Example Embodiment

[0022] Example 2

[0023] Mix 225 mg of modified sodium polyaspartate, 69 mg of sodium gluconate and 7.5 mg of zinc chloride to obtain the water treatment agent of the present invention. Place it in 1 liter of water, stir uniformly, and pre-film for 48 hours. The membrane concentration is 301.5 ppm, and it is diluted to the normal treatment concentration (10-100 ppm) according to the water quality to be treated to obtain a water treatment agent with a normal treatment concentration.

Example Embodiment

[0024] Example 3

[0025] Mix 255 mg of modified potassium polyaspartate, 39 mg of sodium gluconate and 3 mg of zinc sulfate to obtain the water treatment agent of the present invention. Place it in 1 liter of water and stir evenly. The pre-membrane treatment is 48 hours, and the pre-membrane concentration is It is 297ppm, and it is diluted to the normal treatment concentration (10-100ppm) according to the water quality to be treated, and the water treatment agent with the normal treatment concentration is obtained.

Abstract

The present invention discloses one kind of water trating agent with amino sulfuric acid and organic base modified sodium/potassium aspartate as main agent and sodium gluconate and zinc salt as supplementary material. It has simple preparation process, has scale inhibiting and corrosion retarding functions, and is green water treating agent without phosphate and pollution.

Description

technical field [0001] The present invention relates to a kind of anti-scaling, anti-corrosion and environmental protection water treatment agent, specifically, relate to a kind of water treatment agent with polyaspartic acid sodium or potassium modified by sulfamic acid and organic base as the main agent, It is an environmentally friendly agent that prevents scaling, inhibits corrosion, is phosphorus-free, and is pollution-free. Background technique [0002] At present, there are various types of water treatment agents used in circulating cooling water for equipment and air conditioners in various industrial and mining enterprises, but most of them are corrosion inhibitors, scale inhibitors or composite water treatment agents containing phosphorus. Because of their trophic effects, they are discharged in After the waters, it is easy to promote the reproduction of bacteria and algae and form a "red tide", causing water pollution. Especially in the northwestern region of the...
