The alkaline water is beneficial to the human body, the stomach of most people is a weak acid, the right amount of intake of alkaline substances in the body acid-base balance is good; alkaline water is alkaline food can change our unhealthy acidic; water and fats are incompatible, but after the electrolysis of alkaline water can dissolve the grease.
The main components of organic alkaline water treatment agent
With industrial development, the world water crisis is growing worse. Increase of concentration of the circulating cooling water, saving the limited fresh water resources is an urgent task of the current water treatment industry. Order to adapt to the requirements of the high alkalinity, high hardness, high pH of the cooling water chemical treatment, the past 10 years have developed a copolymer type scale dispersing agent, such as the diversity of the HPA / AA, SA / AA, the SS / MA copolymer . Because the structure of such copolymers with a variety of functional groups, the inorganic salts in the water with the role of solubilization, the electrostatic repulsion and lattice distortion, and good scale inhibition and anti-slime. In addition, high calcium tolerance, the higher the dispersion properties of iron oxide.
Due to excellent copolymer DISPERSOR development to promote the development of the phosphorus treatment agent formulations, a variety of new does not contain heavy metals and inorganic polyphosphate organic alkaline water treatment agent done by alkaline water machine in succession between the world. Type of water treatment agents without adding acid to adjust pH, it is safe, but also savings to increase investment and maintenance costs of the acid plant; can run on high concentration, so the savings add water and reduce sewage pollution of the environment;
Enhance the ability of the acid substances in the circulating water system interference. It is a new generation of cooling water treatment agent. Internally developed RP 51, the TS-205, W 331 a, JC 463, SPC, a 502, the QS-03, alkaline water treatment agent, and its performance is basically reach the level of similar foreign products, and in some large-scale petrochemical plant replace imported pharmaceutical products, from the obvious economic and social benefits. Also contributed to the development of China's water treatment technology.
Alkaline cooling water treatment technology is the organic alkaline water treatment agent to the circulating water system does not add acid to adjust the pH value of the processing technology.
Of all organic alkaline water treatment agent generally solid content of 25 to 40 to write about, in general, it is composed of 4 parts.
Scale and Corrosion Inhibitor
Corrosion and scale inhibitors are generally composed of one or two kinds of organic phosphate, hydroxy ethylidene diphosphonic acid (HEOP), amino trimethylene phosphonic acid (ATMP), two phosphono butane 1,2 4-tricarboxylic acid (PBTCA). Two kinds of different proportions of organic phosphonate compound preparation, get a good synergistic effect of corrosion inhibitor fruit better. Organic phosphates is not only a good corrosion inhibitor, in a sense, the more effective for blocking calcium carbonate than most of the polymer. The agent of organic phosphine content can vary according to different water quality and use, usually in 6 to 20%.
DISPERSOR
DISPERSOR composed by copolymers or homopolymers, such as: acrylic hydrocarbon propyl / acrylic acid (HPA / AA), the organic sulfonic acid / acrylic acid (SA / AA), sulfonated styrene / maleic acid (55/MA), maleic anhydride (HPMA), poly (acrylic acid) (PAA), and its content (solids content) is generally 10 to 20%. The scale inhibitor and dispersant is a core component of the organic alkaline water treatment via ionized water filter agent, its performance is good or bad is the key to the application.
Small amount of additives
Copper equipment cooling water system, you can add one or two kinds of copper corrosion inhibitor, such as: sulfur benzene and thiazole (MBT), benzotriazole (BTA), tolyl triazole (TT) its content in general. .5 To 3%, such as MBT and TT composite formula can prevent the dezincification of brass. MBT and BTA complex formula used to prevent pitting and crevice corrosion.
In addition, in order to prevent the organic phosphine-induced decomposition of the role of pH and strong oxidants, can add a small amount of sulfamic acid (SA), cyanuric acid (CA), 5,5-dimethyl has ureide [DMH) The content is generally 3 to 5 percent.
In order to improve the performance of the polymer can also add some surfactants, which can achieve better synergistic effect, for example, fatty alcohol polyoxyethylene ethers or alkyl phenol ethylene oxide condensate of its content is generally 1 to 5%.
Four solvent
Some components, especially the copper corrosion inhibitor, due to the deployment and stability requirements, the deployment of triethanolamine, potassium hydroxide into a certain pH value of solvent content of 20%. Typical of all organic alkaline water treatment agent formulations: 5 to 8% of the organic phosphine, polymer 12 20%, wow class 0.5 of 1% sodium hydroxide to adjust pH to 3-5. The other organic alkaline water treatment formula is: the organophosphorus A + organic farms B + Polymer A 11 Polymer B + azole, with sodium hydroxide to adjust pH to 12 to 4.
