Summary of the invention
The objective of the invention is to provide a kind of water treatment agent prescription, a kind of polyether base phosphonic acids water treatment agent prescription that contains particularly is provided, on prescription, strengthen the scale inhibition treatment effect emphatically.The prescription that screens is the NEW TYPE OF COMPOSITE medicament based on polyether based phosphates, phosphine carboxylic acid and co-polymer of sulfonate.
The objective of the invention is to realize in the following way, prescription mainly comprises: the phosphine carboxylate salt, phosphonate, polyether Quito aminophosphonic acid salt copolymer, co-polymer of sulfonate, the weight percent of each component is a phosphine carboxylate salt (2-phosphono-containing butane-1 in the prescription, 2, the 4-tricarboxylic acid) 12-16%, phosphonate (1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) 8-12%, polyether Quito aminophosphonic acid salt copolymer 25-35%, co-polymer of sulfonate 45-55%.
Characteristics of the present invention are:
1., no zinc, alkalescence, full organic phosphine are prescription.
2., at on-the-spot recirculated cooling water make up water, cycles of concentration can be controlled in 4-6.
3., test-results has reached new water quality monitoring (WQM) controlling index.
4., this prescription medicament uses total concn to be 27-30mg/l, expense is moderate.
5., the prescription in organophosphorus content low (being lower than 4.5mg/l), compliance with environmental protection requirements.
Effect of the present invention is: 1, be adapted at moving under the high basicity condition of water quality of high rigidity (lime carbonate+total alkalinity≤1000mg/l); 2, be standard with the recirculated cooling water make up water, cycles of concentration can be controlled in 4～6; 3, after the formula test operation, its corrosion rate and dirt deposition speed are all less than circulating water quality Monitoring and Controlling index; 4, to use total concn be 27～30mg/l for this prescription medicament, though older prescription slightly increase owing to improved cycles of concentration, reduced the blowdown number of times, thereby prolonged the residence time of medicament in equipment, reduced the medicament waste, so medicament expense does not increase; 5, the raising of cycles of concentration has reduced amount of makeup water, and the water saving expense is comparatively considerable.6, delayed the failure frequency of equipment, reduced the device stop frequency, its economic benefit also is fairly obvious; 7, this prescription is a prescription for no zinc, alkalescence, full organic phosphine.It can simplify technological operation, saves process water, reduces environmental pollution, simultaneously, because it is a research object with Yangtze River Water, can be widely used in similar recirculating cooling water systems such as chemical industry, chemical fibre, has sizable social benefit and promotional value.
