What are the characteristics of safety production in chemical industry companies?
The characteristics of safety production in chemical industry companies are mainly reflected in the following aspects:
1. High material hazard
The raw materials, semi-finished products, finished products, and waste used by chemical industry companies mostly have the characteristics of flammability, explosiveness, toxicity, harm, and corrosion. If preventive measures are not in place during the production process of these hazardous chemicals, they are prone to accidents such as explosions, fires, and poisoning.
2. Complex production process
The chemical production process involves various complex chemical reactions (such as oxidation, reduction, hydrogenation, etc.) and unit operations (such as filtration, evaporation, condensation, etc.). In addition, the complexity of automation control systems (such as DCS, SIS, etc.) also increases the difficulty of safety management.
3. Strict production conditions
Chemical production usually requires extreme conditions such as high temperature, high pressure, low temperature, and high vacuum, which place higher demands on equipment and operators. Even a slight carelessness may lead to accidents.
4. Complex equipment and facilities
There are various types of equipment in chemical industry companies, including pipelines, pressure vessels, reaction devices, etc. These equipment need to go through processes such as chemical synthesis, polymerization, high temperature, and high pressure during the production process. Once out of control, it can easily lead to accidents.
5. Tightness of production methods
Modern chemical production has shifted from traditional manual operations to highly automated and continuous production methods. Production equipment has changed from open to closed, and operations have shifted from manual to instrument controlled. This rigor requires strict management of the production process, without any negligence.
6. Differences in Enterprise Scale and Management
Large chemical industry companies usually have the characteristics of large-scale equipment, complex processes, and high degree of automation, but comprehensive management and process safety management are difficult; Small and medium-sized chemical industry companies generally have problems such as outdated processes, low professional quality of personnel, and low equipment level, leading to frequent accidents.
7. Strong systematic and comprehensive nature
Chemical production involves the supply of raw materials, intermediates, finished products, as well as energy sources such as water, electricity, and steam. At the same time, it also requires the treatment of by-products, exhaust gases, etc. The entire production system is highly comprehensive and systematic.
Summary: The characteristics of safety production in chemical industry companies are mainly reflected in the hazards of materials, the complexity of processes, the strictness of production conditions, the complexity of equipment and facilities, and the strictness of production methods. These characteristics require enterprises to adopt strict safety management measures to reduce accident risks and ensure production safety.

How often do adult dolls need to be cleaned?
About 30 days
The recommended cleaning frequency for adult dolls is to perform a full body deep cleaning every 30 days or so. Whether it's TPE or silicone dolls, regular cleaning not only keeps them clean, but also prevents bacterial growth.
Cleaning methods and precautions
Cleaning frequency: It is recommended to perform a deep body cleaning every 30 days or so.
Cleaning method: Use warm water and antibacterial soap for cleaning, avoid directly rinsing the doll's head and neck in water.
Maintenance interval: Generally, once a month is recommended. First, gently wipe the surface of the doll with a sponge or towel dipped in warm water. If there is dirt on the silicone surface, it can be wiped multiple times with soapy water. Do not apply too much force.
Joint maintenance: Keep the joints of the doll in a natural state, avoiding surface wrinkles and excessive stress caused by prolonged bending.
Painting maintenance: Pay attention to the wiping force and avoid forcefully wiping the doll's facial makeup and eyebrows and eyelashes to avoid color fading or hair loss.
Maintenance after cleaning
After cleaning, wait for the surface to dry before applying prickly ash powder or talcum powder to the doll. Please wear a mask during maintenance to avoid inhaling dust.
