The application of bottle washing machine in lubricating oil cleaning industry has solved the difficult problem of laboratory cleaning. Lubricating oil industry by the application in the social production of various industries, mainly for lubrication, auxiliary cooling, anti-rust, cleaning, tightness and buffer role, is an important branch of the oil industry, generally consists of two parts, base oil and additives, chemical properties of lubricating oil determines its vessels cleaning problem more difficult in the process of inspection, the cleaning method is mainly done 1) artificial high concentration alkali cleaning; 2) Pre-cleaning with gasoline, diesel oil, kerosene, etc., and then cleaning with lye. The workload of the two methods of cleaning utensils is relatively large, and it is easy to cause residual pollutants, which will affect the next test. Moreover, both methods have the risk of occupational exposure of operators. The application of the laboratory bottle washer has brought good news to the laboratory cleaning of lubricating oil.
T he laboratory bottle washing machine can completely solve the problem of lubricating oil cleaning, and can automatically clean, rinse and dry. You only need to put the containers into the laboratory bottle washing machine, and then take out the containers after cleaning.
Two additives and thickeners which are difficult to be cleaned in lubricating oil are verified as cleaning objects. Because they are difficult to be cleaned in lubricating oil inspection, the cleaning degree of them can represent the solution ability of bottle washing machine to lubricating oil cleaning.
Sample source: A branch of Great Wall Lubricating oil of Sinopec:
Containers to be cleaned: 1000mL sampling bottle
Pollutants to be cleaned: 1. Lubricating oil thickener 2. Lubricating oil additive A 3. Lubricating oil additive B
Amount of pollutants to be cleaned: 2/3 of the inner wall area of the bottom of the bottle
The degree of viscosity of the pollutants to be cleaned: at room temperature, the contaminants stuck to the walls of inverted vessels are 1mm thick and difficult to flow out
The cleaning conditions of bottle washing machine in the laboratory
Model: Q720
1L sample bottle single cleaning quantity: between 32 and 42
Precleaning temperature: Precleaning time
Main cleaning temperature: 80℃ main cleaning time: 20min
Cleaner: Alkaline cleaner acidic cleaner
Cleaning water: Purified water from tap water
Drying time: 0.5h
Drying temperature: 120 degrees Celsius
Total time: 1.5h
Verification results:
1. Clean and bright after cleaning; The injected pure water is evenly infiltrated into the inner wall without water droplets or strand flow.
2. No detergent residues were detected by relevant chromatography, and the relevant pollutants were cleaned.
