Abstract
The invention belongs to the research and development technology field of material for water treatment, be specifically related to a kind of hydrophobic membrane dedicated water inorganic agent, described water treatment agent is made up of according to mass percent following material: the water of poly-aspartate 5-7%, polyoxy butanedioic acid 10-13%, polyacrylic acid 2-5%, HPMA 7-10% and surplus. The present invention is mainly used in the cleaning treatment of hydrophobic membrane.
Description
Technical field
The invention belongs to the research and development technology field of material for water treatment, be specifically related to a kind of hydrophobic membrane dedicated water inorganic agent.
Background technology
The interface that the interface that hydrophobic membrane balances each other as film still-process vapour-liquid and heat, matter are transmitted, it rises separation process undoubtedlyVital effect. In film still-process, along with the carrying out separating, because concentration polarization and inorganic salts solubility are with temperatureThe variation of degree, film surface there will be deposit. The hydrophobicity that deposit can destroy film affects the quality of penetrating fluid, affects film simultaneouslyDistillation transmittance process reduces permeation flux, pollutes thereby form film.
In actual application, film distillation may run into the solution of variety classes and concentration, and it is inevitable that film pollutes.Pollute generation but can reduce film, as untreated bitter contains indissoluble inorganic salts, in the time that inorganic salt concentration is lower, by materialInsoluble matter is rejected in liquid pretreatment can effectively prevent sedimental appearance. As in film still-process, add water treatment agent to preventTo the pollution of hydrophobic membrane, ensure system stability, long-acting operation.
Summary of the invention
The object of the invention is to: a kind of hydrophobic membrane dedicated water inorganic agent is provided, its stable performance, applied widely, not brokenBad hydrophobic membrane performance, reaches Production design requirement.
The object of the present invention is achieved like this: a kind of hydrophobic membrane dedicated water inorganic agent, described water treatment agent is by following materialForm according to mass percent: poly-aspartate 5-7%, polyoxy butanedioic acid 10-13%, polyacrylic acid 2-5%, the poly-Malaysia of hydrolysisThe water of acid anhydrides 7-10% and surplus.
Described poly-aspartate is called for short: PASP, polyoxy butanedioic acid are called for short: PESA, polyacrylic acid are called for short: PAA, waterSolution HPMA is called for short: HPMA, above-mentioned material is commercially available product.
Beneficial effect of the present invention: this product has good scale inhibition and dispersion performance, and hydrophobic membrane is had to significant protective effect, greatlyExtend the life cycle of hydrophobic membrane, made the operation that hydrophobic membrane system is long-acting, safe, stable.
Detailed description of the invention

The water of preparation method: add successively in reactor: PASP, PESA, PAA, HPMA and surplus, stirs 1.5Hour, obtain this product.
Embodiment 2, a kind of hydrophobic membrane dedicated water inorganic agent, described water treatment agent is made up of according to mass percent following material:The water of poly-aspartate 7%, polyoxy butanedioic acid 13%, polyacrylic acid 5%, HPMA 10% and surplus.
Preparation method is with embodiment 1.
Embodiment 3, a kind of hydrophobic membrane dedicated water inorganic agent, described water treatment agent by following material according to mass percent groupBecome: the water of poly-aspartate 6%, polyoxy butanedioic acid 11.5%, polyacrylic acid 3.5%, HPMA 8.5% and surplus.
Preparation method is with embodiment 1.
Practical proof: add successively in reactor: PASP60kg, PESA110kg, PAA35kg, HPMA85kg,Water 710kg, stirs 1.5 hours, obtains this product. This product and commercially available prod are carried out to evaluation of antisludging performance contrast test.Water quality is taken from certain coal plant, water quality CaCO3Content is 490mg/L, under identical condition, and dosage: 10mg/L, pointDo not adding this product, commercially available prod. Result is as shown in the table:
| Scale inhibition performance (%) | |
| This product | 99.7 |
| Commercially available prod | 92.4 |
Water quality is taken from certain coal plant, water quality CaPO3Content is 230mg/L, under identical condition, and dosage:10mg/L, is adding this product, commercially available prod respectively. Result is as shown in the table:
| Scale inhibition performance (%) | |
| This product | 99.9 |
| Commercially available prod | 98.1 |
Conclusion: can be found out by above table, this product has good scale-inhibiting properties as hydrophobic membrane dedicated water inorganic agent,Low dosage also has significant scale effect, makes water quality reach hydrophobic membrane operation standard, has reduced the operating cost of enterprise.
