Description
Technical field
The present invention relates to a kind of without phosphorus, no nitrogen and biodegradable fluorescent tracing non-phosphate environment-friendly type polyethers multifunctional water treating agent (APEQYG) and preparation method thereof; Belong to water conditioner preparation and application category; Be applicable to recirculating cooling water system; Be particularly useful for the high calcium cooling water quality, can realize the online detection and the automatic chemical feeding of phosphate-free water treatment agent simultaneously.
Background technology
Use at present more and the scale inhibitor effect preferably water conditioner be mostly phosphoric acid salt; Like hydroxy ethylene diphosphonic acid (HEDP), ATMP (AMP) and 2 – phosphonic acids Ding Wan – 1; 2,4 – tricarboxylic acid (PBTC) etc. are though this type of water conditioner has excellent inhibition tosca performance and corrosion inhibition preferably; But because HEDP, PBTC etc. are because relative molecular mass less (< 600); Functional group is less, and is poor to the inhibition and the dissemination of calcium phosphate scale and ferric oxide particles, to the less stable of zinc salt.Because this type of water conditioner is a large amount of and use widely, cause a large amount of breedings of bacterium algae, the problem of environmental pollutions such as eutrophication of water body at present, therefore developed the demand that low-phosphorous and without phosphorus water treatment agent meets environment protection.
The more phosphate-free water treatment agent of research is the carboxylic-acid water conditioner now; Like hydrolyzed polymaleic anhydride calcium (HPMA), ROHM (PAA), poly-epoxy succinic acid (PESA), copolymer of maleic anhydride and acrylic acid (BC-283) and vinylformic acid-acrylic acid esters co-polymer (T-225) etc., though this type of phosphate-free water treatment agent is to CaCO
