Example Embodiment
[0023] Example 1: Preparation of 20kg cleaning agent.
[0024] Weigh 10% sodium tripolyphosphate, 5% fatty alcohol polyoxyethylene ether (O-20) with a degree of polymerization of 20, 1% potassium hydroxide, and deionized water as the balance. .
[0025] Add the above-mentioned weights of sodium tripolyphosphate, O-20, and potassium hydroxide to deionized water in sequence at room temperature, and stir to a uniform aqueous solution. The cleaning agent has a PH value of 9, and a specific gravity of 1.1g / cm 3 .
Example Embodiment
[0026] Example 2: Preparation of 20kg cleaning agent.
[0027] Weigh 6% sodium phosphate, 5% fatty alcohol polyoxyethylene ether (O-9) with a degree of polymerization of 9, 2% ammonia water, and deionized water as the balance for use.
[0028] At room temperature, add the sodium phosphate, O-9 and ammonia water of the above weight to deionized water in sequence, and stir to a uniform aqueous solution. The cleaning agent has a PH value of 10 and a specific gravity of 1.0g / cm 3 .
Example Embodiment

Abstract
The invention provides a cleaner for the plastic surface, comprising phosphate, surface active agent, pH value regulator and deionized water; the weight percentage of all the components is as follows: 5 percent to 10 percent of the phosphate, 5 percent to 10 percent of the surface active agent, 1 percent to 6 percent of the pH value regulator and the rest is the deionized water; the pH value of the mixing liquid of the components is 9 to 10; the cleaner has the functions of high efficiency and easy cleaning to the plastic surface, can clean the oil stain on the plastic surface completely, also can shorten the cleaning time and improve the working efficiency; the cleaner is an alkaline water-soluble cleaner, does not contain harmful material to the human body, meets the requirements of environment protection, has low corrosion to the equipment, effectively reduces the production cost and has safe and reliable use; and the cleaned waste liquid is convenient to be treated and discharged.
Description
technical field [0001] The invention relates to a cleaning agent, in particular to a water-based plastic surface cleaning agent. Background technique [0002] Cleaning the materials of various products before processing is an important process in the production process. For high-tech products, cleaning the processed materials is a key process. The cleanliness of processed materials is related to the performance, quality, service life and reliability of products, especially high-tech products have the characteristics of high performance, high reliability, high precision, high integration and miniaturization, and are very sensitive to cleanliness , Minor pollution will have a serious impact on the performance, quality, service life and reliability of the product. Therefore, improving the cleanliness of processed materials has become an important topic to improve product performance, quality, service life and reliability. [0003] The number of products and components prepare...
