Problems solved by technology

[0009] The present invention has designed a kind of water quality stabilizer, and the technical problem that it solves is: (1) calcium gluconate is used as one of water quality stabilizer components when preparing, using traditional manufacturing process and catalyst to exist yield low, harsh reaction conditions And defects such as complicated equipment structure; (2) existing by immobilized enzyme preparation calcium gluconate process exists carrier microsphere surface area is limited, can't load too much enzyme protein, makes enzyme activity recovery rate lower; (3) due to mass transfer The effect of resistance, the H generated during the reaction 2 o 2 It cannot be decomposed quickly, resulting in the inactivation of GOD and CAT, and the immobilized enzyme loses most of its enzyme activity soon after continuous use

Embodiment 1

[0024] Embodiment 1: a water quality stabilizer, prepared from the following raw materials in parts by weight: 20 parts of polyaspartic acid, 30 parts of sodium polyacrylate, 30 parts of calcium gluconate, 10 parts of sodium molybdate, 10 parts of vegetarian and 100 parts of water.

[0025] Among them, the preparation process of calcium gluconate is as follows:

[0026] Using 2% (v / v) ethylenediamine solution as the amination reagent, the average pore diameter of the carrier is 100-200nm, and the carrier is dispersed in 2% (v / v) amination reagent according to the quality of the carrier: the volume of the amination reagent is 1:40 in pH 8.0, 200 rpm shaking reaction at 60 °C for 2 h, and the aminated carrier was collected.

[0027] According to the ratio of GOD:CAT activity ratio of 1:2, GOD and CAT were dissolved in 0.1 mol / 1 phosphate buffer at pH 6. Add 0.2% (w / v) carbodiimide and 0.2% (w / v) N-hydroxysuccinimide to the enzyme dissolving solution, react at 8°C for 60 min, d...

Embodiment 2

[0030] Embodiment 2: a water quality stabilizer, prepared from the following raw materials in parts by weight: 25 parts of polyaspartic acid, 45 parts of sodium polyacrylate, 34 parts of calcium gluconate, 5 parts of sodium molybdate, wood 10 parts vegetarian and 90 parts water.

[0031] Among them, the preparation process of calcium gluconate is as follows:

[0032] Using 2% (v / v) ethylenediamine solution as the amination reagent, the average pore size of the carrier is 400-500nm, and the carrier is dispersed in 2% (v / v) amination reagent according to the quality of the carrier: the volume of the amination reagent is 1:40 in pH 8.0, 200 rpm shaking reaction at 60 °C for 2 h, and the aminated carrier was collected.

[0033] GOD and CAT were dissolved in 0.1 mol / l phosphate buffer at pH 6 in a ratio of GOD:CAT activity ratio of 1:2. Add 0.2% (w / v) carbodiimide and 0.2% (w / v) N-hydroxysuccinimide to the enzyme dissolving solution, react at 8°C for 60 min, disperse the aminated...

Abstract

The invention relates to a water quality stabilizer prepared from the following raw materials in parts by weight: 20-30 parts of polyaspartic acid, 30-45 parts of sodium polyacrylate, 30-34 parts of calcium gluconate, 5-10 parts of sodium molybdate, 5-10 parts of lignin and 80-1000 parts of water. The invention provides a new technique for preparing calcium gluconate through the water quality stabilizer; and through the new technique, the yield of calcium gluconate is high, the reaction conditions are mild, and the devices are easy to acquire, so that the new technique is a green and environment-friendly production technique.

Description

technical field [0001] The invention relates to a water quality stabilizer, in particular to a low-toxicity environment-friendly water quality stabilizer. Background technique [0002] In the circulating cooling water system, scaling and corrosion are common problems, which seriously affect the economic benefits of the product. Scale and corrosion problems. Chemicals added to circulating cooling water to prevent corrosion and scaling of equipment by cooling water. It can form stable complexes with scale-forming substances such as calcium and magnesium ions in water. It is easily soluble in water and has good chelating, dispersing and corrosion inhibition functions, preventing scaling and loosening the old scale layer, which is convenient for cleaning. dirt. It has good corrosion and scale inhibition effects on carbon steel and stainless steel, which can improve the heat exchange effect of the equipment, prolong the service life of the equipment, and save water, energy and...
