Problems solved by technology

[0002] At present, many products with overflow after packaging need to be processed. Soaking liquid is generally used. It only needs to be soaked, and the cleaning can be completed by rinsing after soaking. Amide is the main raw material, and the soaking solution produced by it is strongly acidic, which will corrode the product during use, and will decompose into toxic gas during soaking and use, which is harmful to the operator's body, and ordinary soaking solution can only be used at high temperature Operating at 110 to 130°C, and the low-temperature soaking solution directly increases the company's use cost due to the high cost of preparation materials and complicated process

Embodiment 1

[0018] A low-temperature alkaline soaking solution consists of 100 grams of potassium hydroxide, 50 grams of butyl glycol ether, 830 grams of pure water and 20 grams of surfactant (molecular weight: 2000). The preparation method is to put 100 grams of potassium hydroxide, 50 grams of ethylene glycol butyl ether, 830 grams of pure water and 20 grams of surfactant into a beaker, and heat the solution in the beaker to 20 ° C, and use a stirrer to fully Stir for 3 hours, filter the stirred mixed solution with 1um filter paper, and obtain 1000 grams of low-temperature alkaline soaking liquid finished product. The filter paper is easy to use and cheap, and can meet the needs of this product.

[0019] After soaking the obtained low-temperature alkaline soaking liquid with spilled products after packaging, the cleaning methods are as follows: 1. Soaking; 2. Washing; 3. High-pressure water washing; 4. Appearance inspection. And record the data in Table 1 below:

Abstract

The invention discloses a low-temperature alkaline soak solution and a preparation method thereof. The low-temperature alkaline soak solution comprises, by mass, 10 to 20% of potassium hydroxide, 5 to 15% of ethylene glycol monobutyl ether and 2 to 6% of surfactant, with the balance being pure water. The preparation method comprises the following steps: successively adding pure water, potassium hydroxide, ethylene glycol monobutyl ether and surfactant into a material mixing tank; carrying out uniform mixing under stirring so as to obtain a mixture solution; and introducing the mixture solution into a filter for filtering so as to finally obtain the low-temperature alkaline soak solution. The preparation method for the low-temperature alkaline soak solution has the characteristics of easiness, stable reaction, high production efficiency, no toxicity, low corrosivity, easy treatment of waste water, etc.
