Embodiment 1

[0023] Embodiment 1: configure 20kg cleaning agent.

[0024] Weigh 10% sodium tripolyphosphate by weight, 5% fatty alcohol polyoxyethylene ether (0-20) with a polymerization degree of 20, 1% potassium hydroxide, and deionized water as the balance, and set aside.

[0025] Add the sodium tripolyphosphate, 0-20 and potassium hydroxide of the above weight into deionized water in sequence at room temperature, and stir until a uniform aqueous solution is obtained. The pH value of the cleaning agent is 8, and the specific gravity is greater than 1.0g / cm 3 , the viscosity is 0.9mPas.

Embodiment 2

[0026] Embodiment 2: configure 20kg cleaning agent.

[0027] Weigh 6% trisodium phosphate, 5% fatty alcohol polyoxyethylene ether (0-40) with a polymerization degree of 40, 1% potassium bicarbonate, and deionized water as the balance, and set aside.

[0028] Add the above-mentioned weight of trisodium phosphate, 0-40 and potassium bicarbonate into deionized water in turn at room temperature, and stir until a uniform aqueous solution is obtained. The pH value of the cleaning agent is 8, and the specific gravity is greater than 1.0g / cm 3 , The viscosity is between 0.9mPas.

Embodiment 3

[0029] Embodiment 3: configure 20kg cleaning agent.

[0030] Weigh 6% dipotassium hydrogen phosphate, 5% fatty alcohol polyoxyethylene ether (0-30) with a polymerization degree of 30, 2% sodium hydroxide, and deionized water as the balance, and set aside.

[0031] Add the dipotassium hydrogen phosphate, 0-30 and sodium hydroxide of the above weight into deionized water in sequence at room temperature, and stir until a uniform aqueous solution is obtained. The pH value of the cleaning agent is 9, and the specific gravity is greater than 1.0g / cm 3 , the viscosity is 1.0mPa.

Abstract

The invention provides a cleaner for glassware in a laboratory, 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, 0.5 percent to 2 percent of the pH value regulator and the rest is the deionized water; the pH value of the mixing liquid of the components is 8 to 10; the cleaner has the functions of high efficiency and easy cleaning to the glassware in the laboratory, can clean the oil stain and spots on the plastic surface completely, can prevent stain on the surface of glassware in the laboratory, also can shorten the cleaning time and improve the working efficiency; the cleaner is a 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 laboratory glassware cleaning agent. Background technique [0002] Laboratory glassware is the necessary experimental equipment in scientific research and development, education and inspection work. The cleanliness of laboratory glassware will affect the accuracy of experimental data to varying degrees, thereby affecting the accuracy of experimental results. Therefore, ensuring the cleanliness of laboratory glassware and reducing human errors in experiments is a necessary part of laboratory work. Laboratory glassware is widely used in the laboratory, such as petri dishes, beakers, conical flasks, funnels and titration bottles, etc. The cleanliness of these equipment will affect the experimental results, and in severe cases will cause the entire Experiment failed. Therefore, in order to maintain the cleanliness of laboratory glassware, it must be cleaned during its processing a...
