Problems solved by technology

However, for water with high alkalinity and high hardness, the scale inhibition ability and slow release effect are significantly reduced, and the stability to zinc salts is weak
In the daily use of chemicals, the concentration of chemicals is monitored by adding tracers, but the tracers added in traditional phosphorus-free antiscalants have poor stability and cannot correctly reflect the concentration of chemicals in water quality

Abstract

The invention belongs to the technical field of water treatment, and particularly discloses a non-phosphorus antisludging agent containing tracer polymer and a preparation method of the non-phosphorusantisludging agent. The antisludging agent is prepared from the following raw materials: (1) AA / AHPSE; (2) zinc chloride; (3) polyaspartic acid; (4) organic amine; (5) triethanolamine; (6) polyepoxysuccinic acid; (7) sodium gluconate; (8) hydrogen peroxide; (9) a tracer agent PTSA; and (10) the balance of pure water. The prepared non-phosphorus antisludging agent containing tracer polymer is a water treatment antisludging agent having the good effect, low cost, high antisludging capability, and capable of being monitoring adding and usage conveniently, and has oustanding social benefits andeconomic popularization value.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and specifically discloses a phosphorus-free scale inhibitor containing a tracer polymer and a preparation method thereof. Background technique [0002] At present, most of the traditional phosphorus-free scale inhibitors sold in the market are AA / AMPS (acrylic acid / 2-acrylamide-2-methylpropanesulfonic acid). Traditional phosphorus-free scale inhibitors have acceptable scale inhibition ability for water with general alkalinity and hardness. However, for water with high alkalinity and high hardness, the scale inhibition ability and slow release effect are obviously reduced, and the stability of zinc salt is weak. In the daily use of chemicals, the concentration of chemicals is monitored by adding tracers, but the tracers added in traditional phosphorus-free antiscalants have poor stability and cannot correctly reflect the concentration of chemicals in water quality. Therefore, the resear...
