Is silk screen printing harmful to the body, and what harm does silk screen printing do to the human

There are some effects on the body.

Silk screen printing. A variety of inks can be used, so different colors of products can be printed, and some special inks can also be applied. Therefore, the method of printing is relatively powerful, and the effect of printing is relatively good, and the industry is relatively adaptable.

The pressure generated by screen printing is relatively small, so the compressibility of the printed product is relatively small, so that the overall printing effect can be ensured. For some fragile goods, printing operations can also be carried out, so this printing method is widely used.

Benzene and xylene in washing water and various solvents are more harmful to the human body, especially benzene, I am studying chemistry, mainly involving benzene are toxic, should try to avoid contact with the body, do a good job of protection when working, usually drink more pure milk can neutralize the toxins inhaled in the body.

To do silk screen printing to contact some chemical things, ink, solvents, chemical things are toxic, which has to have requirements for the working environment, to have a good ventilation effect, pay attention to their own prevention, the problem is not big, you can drink a glass of milk every morning,

Summary. Hello, I am glad to answer for you, silk screen printing may cause damage to the human body, blood vessels, trachea, bronchi, lungs and other body-related trachea. These injuries are related to the inks, thinners, pigments, fuels, etc. used in silk screen printing.

Hello, I am glad to answer for you, silk screen printing may cause damage to the human body, blood vessels, trachea, bronchi, lungs and other body-related trachea. These injuries are related to the inks, thinners, pigments, fuels, etc. used in silk screen printing.

Silk screen printing ink contains solvents, through contact, into the body, will damage the human body and subcutaneous fat, long-term contact will make the first crack, rough; It is sucked into the trachea, bronchi, lungs, or transmitted to other parts of the body through blood vessels and lymphatic vessels, and may even cause chronic poisoning. Some inks have the toxicity of heavy metal ions, and pigments and fuels contain carcinogenic ingredients, which are extremely harmful to the human body.

<> <> "Hello! Glad to serve you! Silk screen printing is also called screen printing, guessing is a common way in printing, in the process of printing will generally use some ink, the smell of ink will cause certain harm to the human body.

Silk screen printing contains a certain toxic odor, if inhaled for a long time, it is likely to cause some respiratory diseases, and long-term exposure may also cause some ** diseases, which need to be strictly and safely operated. In the process of screen printing, some inks are generally used, and the ink usually contains certain chemicals and organic solvents, and long-term inhalation will lead to respiratory diseases, such as bronchitis and other diseases, manifested as phlegm, cough, etc. Therefore, if there are obvious uncomfortable symptoms, you should seek medical attention in time, and follow the doctor's instructions to take targeted medication according to different conditions.

People who have been exposed to silk screen printing for a long time may also have **inflammation, such as the problem of dry cracking and roughness will occur in the case of hunger, in this case, we must do a good job of nursing during the operation, and wear professional gloves to avoid damage to **. To sum up, if you are a person who has been exposed to silk screen printing for a long time, you must do a good job of regular check-ups, detect diseases as soon as possible and ** as soon as possible, so as not to affect your own health.

Ink is currently the largest source of pollution in the printing industry, and the world's annual output of ink has reached 3 million tons. Hundreds of thousands of tons of global volatile organic compounds (VOCs) pollution are emitted by inks every year. These organic volatiles can form a more serious greenhouse effect than carbon dioxide, and will form oxides and photochemical smog under sunlight, which seriously pollutes the atmospheric environment and affects people's health.

In addition, heavy metals and other harmful ingredients in ordinary inks for packaging and printing of food, toys and other packaging will directly endanger the health of the eater.

1) Effects on human health.

Printing inks are composed of pigments, binders, solvents, and auxiliaries. Among them, organic solvents and heavy metal elements are seriously harmful to the human body. There are two types of pigments in inks - inorganic and organic, both of which are insoluble in water and other media, and have bright color and stability.

Some inorganic pigments contain heavy metal elements such as lead, chromium, copper, mercury, etc., which are toxic and cannot be used in printed food packaging and children's toys. Some organic pigments contain biphenyl gum, which has carcinogenic ingredients and should be strictly prohibited. Organic solvents can dissolve many natural resins and synthetic resins, which are important components of various inks, but some of them will damage the human body and subcutaneous fat, and long-term contact will make **dry cracks, rough, if infiltrated into ** or blood vessels, it will endanger human blood cells and hematopoietic function with blood; It is sucked into the trachea, bronchi, lungs or through blood vessels, lymphatic vessels to other organs, and may even cause chronic poisoning of the body. Some inks have the problem of toxicity of heavy metal ions, and pigments and dyes contain carcinogenic ingredients, which are very harmful to human health.

Composite packaging materials use a large number of inks, organic solvents and adhesives in printing, although these accessories are not in direct contact with food, but in the process of food packaging and storage, some toxic substances will migrate into the food, endangering people's health. Ethanol, isopropanol, butanol, propanol, butanone, ethyl acetate, butyl acetate, toluene, xylene and other organic solvents are often used in printing inks. Although most of these solvents can be removed by drying, the residual solvents will migrate into the food and harm the human body.

The solvents used in gravure inks generally include butanone, xylene, toluene, butanol, etc. In particular, the residual smell of butanone is strong. Because the pigment particles in the ink are very small and the adsorption force is strong, although it has been heated and dried during printing, it is often not completely dried due to the short time and fast speed, especially the printing matter with a large inking area and a thicker ink layer, and its residual solvent is more.

These residual solvents are brought to the compounding process, where they are more difficult to escape after compounding and slowly migrate and penetrate, so solvent residues must be kept to a minimum.

Now they are advocating a new type of environmentally friendly UVLED screen printing ink.

Contact with screen printing ink causes chronic poisoning to the human body, and the toxicity is aggravated after inhalation of ink gas. It mainly affects the liver and kidneys and immune system.

If the methanol content in the ink is high and inhaled more, it will also affect people's glasses.

Suggestion: The working environment should be well ventilated.

The biggest hazard comes from the chemical ingredient lead. Printing oils contain very high levels of lead. Lead weakens the body's resistance to pathogenic microorganisms and increases susceptibility. The main reason is that lead inhibits the function of T cells, which greatly weakens their immune regulation ability.

Specifically: (1) Affect the metabolism of growth hormone: The thyroid gland is the largest endocrine gland in the human body, which synthesizes and secretes thyroxine to promote the metabolism of substances and energy in the body (promote growth and development).

The function of thyroid synthesis and secretion of thyroxine is controlled and regulated by two parts, one is the thalamus and the other is the pituitary gland. Lead has an inhibitory effect on these two parts, hindering the physiological function of the thyroid gland, that is, affecting the synthesis and release of growth hormone, thereby delaying physical development.

2) Direct impact on bone growth: More than 90% of the lead in the body is accumulated in bone tissue, and the accumulation of bone lead begins in the fetal period, and then gradually increases with age, which can last for about 50 years. Excess lead accumulates in long bone tissues and directly affects bone growth.

3) Indirectly affects bone growth: Lead indirectly affects bone growth by altering circulating hormone levels and affecting vitamin D3 levels. Lead also directly affects or replaces the deposition of calcium in the bones, which affects bone growth.

4) The damage of lead to the cardiovascular system is mainly manifested in three aspects:

1) Cardiovascular mortality is closely related to excess lead in arteries, and the blood lead and 24-hour urine lead levels in cardiovascular patients are significantly higher than those in non-cardiovascular patients.

2) Elevated lead levels can cause high blood pressure.

3) Elevated lead levels can cause heart disease and changes in heart function.

Therefore, if you do printing work, it is best to avoid direct contact with the body and ink as much as possible.

Silk screen printing is a heavily polluting process. First of all, the plate-making process produces a developer, the ink used produces an ink barrel, and the cleaning process produces cleaning wastewater or waste rags.

In general, it is less harmful to the human body. As long as you drink plenty of water and wash your hands regularly, you can prevent the effects of these small hazards.

Chemicals are harmful to the human body.

The factory won't tell you.

Such as gas volatilization, ** exposure, respiratory tract absorption, heavy metals and other specific hazards, depending on what preparations you have used.

Yes At the very least, it's chemicals, a little bit.
