Effect test

Embodiment 1

[0031] The 30% water-containing trichloroisocyanuric acid and acrylic acid-AMPS copolymer (38% aqueous solution) were mixed and dried in an oven at 100°C for 1 hour. The bactericidal and scale inhibitor with the content of the scale inhibitor of 0.5%, 1.0%, 5.0%, and 10.0% is prepared. The dosage of each component is shown in Table 1. Use standard iodometry to determine available chlorine content. The anti-scaling performance of the anti-scaling agent and the determination of calcium ions are respectively determined by the static anti-scaling evaluation method and the EDTA titration method in the "China Petrochemical Corporation Cooling Water Analysis and Test Method". The specific test conditions are shown in Table 2. The test results are shown in Table 3.

Embodiment 2

[0047] Mix 30% water-containing trichloroisocyanuric acid and acrylic acid-AMPS-non-ionic copolymer (38% aqueous solution), and dry in an oven at 100°C for 1 hour. The bactericidal and scale inhibitor with the content of the scale inhibitor of 0.5%, 1.0%, 5.0%, and 10.0% is prepared. The dosage of each component is shown in Table 4. The test of the available chlorine content, the test of the scale inhibitor's anti-scaling performance and the specific test conditions are the same as in Example 1. The test results are shown in Table 5.

[0052] Experiment number

[0053] Similar to the acrylic acid-AMPS copolymer, adding 1 ppm of acrylic acid-AMPS-nonionic copolymer can achieve a significant scale inhibition effect.

Embodiment 3

[0055] Mix 30% water-containing sodium dichloroisocyanurate and acrylic acid-AMPS-nonionic copolymer (38% aqueous solution), and dry in an oven at 100°C for 1 hour. The bactericidal and scale inhibitors with 0.5% and 1.0% scale inhibitors were prepared. The dosage of each component is shown in Table 6. The test of the available chlorine content, the test of the scale inhibitor's anti-scaling performance and the specific test conditions are the same as in Example 1. The test results are shown in Table 7.

Abstract

The invention relates to a solid composite sterilizing scale inhibiting agent, in particular to a solid composite sterilizing scale inhibiting agent which is suitable for the sterilization and scale removal of a swimming pool or industrial circulating cooling water. The solid composite sterilizing scale inhibiting agent is characterized by comprising the following components by the total weight of the solid composite sterilizing scale inhibiting agent: 85-99.9 percent of sterilizing agent and 0.1-15 percent of scale inhibiting agent, wherein the sterilizing agent is selected from trichloroisocyanuric acid, dichloroisocyanuric acid or salt thereof. The invention maintains the efficient sterilizing effect of the sterilizing agent and simultaneously provides an efficient scale inhibiting function. In addition, because a solid scale inhibiting agent thin layer is coated on the surface of a particle of the solid sterilizing agent, the decomposition of the sterilizing agent during storage is effectively retarded, the chlorine odor sent out by a product is greatly reduced, and the stability of the product during storage is improved.

Description

Technical field [0001] The invention relates to a solid composite slow-release sterilization and scale inhibitor, which is mainly used for sterilization and scale inhibition of swimming pools and industrial circulating cooling water. Background technique [0002] Trichloroisocyanuric acid and dichloroisocyanuric acid and their salts have excellent bactericidal properties. They are a new generation of broad-spectrum, high-efficiency, low-toxic bactericides, bleaches and shrink-proof agents. Trichloroisocyanuric acid and dichloroisocyanuric acid and their salts can kill almost all fungi, bacteria, and virus spores. They have specific effects on killing hepatitis A and hepatitis B viruses, as well as sex viruses and HIV. Good disinfection effect, safe and convenient to use, mainly used for disinfection and sterilization of swimming pools, industrial circulating water, restaurants, hotels, public places, homes, hospitals, poultry eggs, and fish disease prevention.
