These chemicals can include: Household Chemical,Household Cleaning Stainless Steel Cleaner,Household Cleaning Polish,Household Chemicals Cleaner Jiangyin yinghuameng Houseware Co.,Ltd. , https://www.nbcare-guys.com
Recently, the “Eleventh Five-Year†National Science and Technology Support Program project “Study on hot water calorie measurement standards and traceability technology†was completed by experts. The hot water calorie measurement standard set up by this project is obviously higher than the existing domestic devices in terms of accuracy, stability and reliability, and solves the problems of lack of detection means of heat meters and scientific methods of detection methods.
The heat meter is a measuring instrument installed in the heating circuit to measure heat supply. Compared with the previous method of calculating the heating price according to the area of ​​the house, using the heat meter as a charging basis is more energy-efficient and scientific. However, the time for hot water heat metering in China is short and faces various problems.
In response to these problems, China Metrology Institute cooperated with Beijing Thermal Power Group and other units to jointly establish a standard device for large-caliber, high-precision primary-grade hot water flow and a new standard device for measuring temperature and temperature difference, and developed a heat meter interface form and communication protocol. The development of the heat meter infrared reading system was completed for the use of a heat meter standard device. In addition, it also revised the heat meter verification procedures and type evaluation program, and improved the hot water calorie quantity traceability system.
1. Cleaning agents: These are substances used to clean surfaces, floors, and appliances. Examples include bleach, ammonia, and dishwashing detergent.
2. Disinfectants: These are chemicals used to kill germs and bacteria on surfaces. Examples include hydrogen peroxide, rubbing alcohol, and chlorine.
3. Pesticides: These are chemicals used to control pests such as insects, rodents, and weeds. Examples include insecticides, rodenticides, and herbicides.
4. Solvents: These are chemicals used to dissolve other substances. Examples include acetone, paint thinner, and gasoline.
5. Personal Care products: These are chemicals used for personal hygiene and beauty. Examples include shampoo, soap, and lotion.
It is important to use household chemicals safely and according to the manufacturer's instructions to avoid accidents and health risks.
Classification of household cleaners
1. According to the form, they can be divided into liquid and solid (powder and paste).
2. According to the acidity and alkalinity, it can be divided into acid cleaner, medium cleaner and alkaline cleaner.
3. It can be divided into Kitchen Cleaner, Bathroom Cleaner, laundry detergent, Glass Cleaner, leather cleaner, carpet cleaner, etc.
