Abstract

A antifouling coating for circulating water of cooling tower consists of potassium and sodium sodium silication, silica gel, rosin, cuprous oxide, zinc oxide, quartz powder and water, which includes 36.0-39.4 percent by weight of potassium and sodium sodium silication, 2.5-5.5 percent by weight of silica gel, 1.3-1.9 percent by weight of rosin, 32.8-35.8 percent by weight of cuprous oxide, 6.2-8.2 percent by weight of zinc oxide, 1.5-2.4 percent by weight of quartz powder, and the rest water. The antifouling coating of the invention is coated on the inner wall of the cooling tower, which can effectively prevent the attachment and breeding of the moss bacteria and algae, so the qualified rate of anaerobic bacteria of the cooling water in the system can reach up to 95-100 percent, and the water turbidity is obviously decreased. The state without algae and water living life-forms can remain for 3-4 years, which is beneficial for environmental protection and beautification of water field, and decreases the sewage amount and pollution discharging times to ensure the normal operation of the device.

Description

technical field [0001] The invention relates to an antifouling paint, in particular to an antifouling paint used for circulating water cooling towers. Background technique [0002] The circulating water system in chemical production has requirements on the water turbidity and the pass rate of heterooxygen bacteria, but the inner wall of the cooling tower is more likely to breed and attach moss algae, resulting in a large number of bacteria and slime in the circulating water system, which is difficult for water quality treatment. It will bring a lot of troubles to sewage and sewage, because the generated bacteria and algae will block the pipes, and even cause equipment failure or accidents. Biocide is usually used to kill algae and moss, or to interrupt production, clean the inner wall of the cooling tower, and remove moss, algae, sludge, etc. These methods have a certain decontamination effect, but not ideal, need to increase costs or affect normal production.
