Glassware is divided into ordinary glassware and special glassware
There are two types of dirt on the attached glass utensils. One category can be cleaned with water, and the other is to use cleaning agents or special detergents to clean. In the experiment, no matter what kind of dirt attached to the glass utensils, the utensils used should be cleaned immediately.
Glass utensils of sugar, salt, starch, mud sand, alcohol and other substances can be washed with water to achieve the purpose of cleaning. It should be noted that if the attached dirt is dry, the utensils can be soaked in the water for a while, and then brushed with a hair brush until was washed.
The glassware is stained with oil or prevailing with animals and vegetable oils. It can be cleaned with washing powder, decontamination powder, and detergent. When cleaning, use a brush to wash, and use this detergent to clean the glassware with organic oil. After the glassware was cleaned with detergent, it was also rinsed with water.
Glassware with coke, asphalt or other polymer organic matter should be cleaned with organic solvents, such as gasoline and benzene. If it is difficult to wash, soak the glassware into an alkaline detergent for a period of time, and then use a solution such as sodium carbonate, sodium bicarbonate, sodium hydroxide or sodium phosphate with a concentration of more than 5%. Essence
In chemical reactions, metal, oxide, acid, alkali and other dirt on the wall of the glassware is often attached. When cleaning, according to the characteristics of dirt, use strong acid, strong base cleaning or use of neutralized chemical reactions, and then rinse with water. When cleaning the pH, pay special attention to safety. The operator should bring rubber gloves protective mirrors. Darma, clips and other tools should be used during operation.
Optical glass surface is moldy and is a common phenomenon. When the optical glass is mildew, the light will scatter the surface to make the imaging blur, and severe cases will scrap the instrument. The cause of optical glass is mostly due to microbial spores on the surface. When the temperature and humidity are appropriate, and there is a need for nutrients, it will grow quickly and form moldy spots. It is particularly important to prevent mildew and preventing and moisturizing. Once mildew spots are produced, it should be cleaned immediately.
To eliminate mildew, cleaning mold can be cleaned with 0.1 ～ 0.5%ethyl -based hydrogen chloride silane and water -free alcoholic cleaning agent. A small amount of ether should be mixed with wet tide, or washed with oxylene oxide, dilute ammonia water, etc. Essence
Using the above cleaning agent can also clean the oil on the optical glass, hydrophilic mist, and oil and water mixed fog.
