Anonymous users2024-02-10The effects of electroplating on the body are not achieved overnight, but are a long-term accumulation process, which is mainly divided into the following three categories:
1. Dust hazards: A large amount of dust may contain silicon, chromium, aluminum, iron, copper and linen will be produced during the operation, which will bring serious occupational hazards to workers. Most organic solvents are toxic, trichloroethylene poisoning can cause rash, fainting, high fever, lymphoma, and finally cause a variety of complications, until **ulcer, liver and kidney failure and death; Benzene poisoning mainly affects the hematopoietic function of the human body, causing leukopenia in mild cases, aplastic anemia in severe cases, and finally leukemia; Carbon tetrachloride can cause serious damage to the liver and kidneys.
In addition, electrochrome plating will emit a large amount of chromium mist, chromium compounds can cause ulcers, anemia, nephritis and neuritis and other diseases, and have the effect of carcinogenic and inducing gene mutations.
2. Risk of electric shock: human contact with high-voltage and low-voltage power sources may cause electric shock accidents. Many electrical equipment are used in electroplating production, such as polishing machines, rolling machines, rectifier power supplies, cranes, centrifugal dryers, electric ovens, electric heaters, filters, barrel plating machines and sewage treatment equipment, etc., and their input voltages are generally very high.
In addition, the working site of the electroplating workshop is damp and the equipment is susceptible to corrosion, so in the process of use and maintenance, if the equipment is not operating normally, the protective measures are not effective or the operation is wrong, it is easy to cause electric shock accidents.
3. Other hazards: In addition to the above main hazards, there may also be noise hazards (such as ultrasonic cleaning, compressed air drying, etc.), mechanical injuries and lifting injuries in electroplating production. Take cyanide as an example, cyanide is one of the commonly used chemical raw materials in electroplating, which is very easily absorbed by the human body and can enter the human body through the mouth, respiratory tract or healthy **.
Cyanide enters the stomach under the dissociation of gastric acid, can be immediately hydrolyzed into cyanogenic acid and absorbed, after this substance enters the blood circulation, the fe3 of cytochrome oxidase in the blood combines with cyanide to generate cyanide iron cyanide cytochrome oxidase, loses the ability to transfer electrons, interrupts the respiratory chain, and the cell suffocates and dies. Due to the large solubility of cyanide in lipids, the central nervous system is the first to be harmed, especially the respiratory center is more sensitive.
Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on some metal surfaces, and it is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, so as to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. Many coins also have electroplated outer layers.
The main thing is that it is particularly harmful to the lungs, and it is often reported that a smoking lung is compared with a non-smoking lung, and the results are clear at a glance, and the smoker's lungs are too scary.
Long-term Internet access or playing on the computer mainly have the following drawbacks: 1. Eye diseases: According to hospital ophthalmology experts, patients are blind because the picture on the screen is jumping up and down, left and right, changing rapidly, and the person who plays stares at the screen intently, making the eyes overtired, causing myopia in the light, and retinal detachment in the heavy, causing serious visual impairment and sudden blindness, that is, temporary or permanent blindness. >>>More
I remember a few years ago I have been asking adults like this, when will I grow up, day by day, from a yellow hair to grow into a college student, this is also a blink of an eye, the things of the hour are still vivid, as if it happened yesterday, grow up, not good, now I often say to my mother that I really want to be smaller, the pressure of life is ready to attack me before I can be independent, I can only giggle, it is not good to grow up, but also think that people are strange animals, When I was a child, I hope that I will grow up quickly but I hope that I will never grow up, facing the door of society, I can't help but be afraid, can I cope with such a society, or when I was a child, there is something to hide behind my mother, and now there is something to do, I can only solve it myself, my mother can only stand next to me and put forward opinions, and in the future, I will stand in front of my mother, and I will block it, this is the process of human growth, running from back to front, growing up is really bad, what is good about growing up, I want to grow up in the child who can understand the hardships of growing up, fall to get up by yourself, tears to swallow in the stomach, can not show their weakness to others, because it is an adult, to be a role model, injured, can not cry pain, or keep moving forward, even if the feet are worn out, the society does not allow us to stay too much, once we stay, it is backward to be abandoned, it is really bad to grow up, for the sake of life, everything is carried by yourself, tired can not say, can not fall, because there is still a person behind to protect, When I fall, it's the end of a person, and it's not good to grow up, but I still have to keep going. Because I want my future.
1. Hiding at a certain time, missing the palm prints of a period of time; Hiding in a certain place, missing someone who stands on the way and on the way out, makes me worry. >>>More
There is no best, they all have their own strengths, and the tanks that have always been bullish have entered small neighborhoods and still do not die? Now although the United States has the F-35 and Russia has the Su-47, so what? There will be better planes in the future.
