Harm of screen printing pad printing ink to human body and how to control it

ink is composed of pigment, binder, solvent and auxiliary agent. Some of them use pigments with unqualified heavy metals exceeding the standard, which are toxic to some extent and cannot be used in printing industry. Some organic pigments contain biphenyl glue, which is carcinogenic and should be strictly prohibited. In addition, some inks contain halogens, including five elements such as fluorine, chlorine, bromine, iodine and astatine, which are collectively called halogens. Most organic halides are synthetic products. They are widely used in various fields, such as flame retardants, refrigerants, solvents, organic chemical raw materials, pesticides, bleaches and wool degreasing agents, because of their excellent performance, such as flame retardant, easy dissolution and high reactivity. Organic halogen compounds can cause cancer in human body, and their low biodegradation rate will lead to the accumulation in the ecosystem, and some volatile organic halide pairs. Therefore, when you buy ink, you should carefully read SGS and ROHS reports to see if the ingredients in it exceed the standard. Hengjin Suzhou pad printing screen printing halogen-free ink does not contain heavy metals and halogens, so you can use it with confidence. 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. Long-term contact will make the skin chapped and rough. If it penetrates into the skin or blood vessels, it will endanger people's blood cells and hematopoietic function with blood. It is inhaled into trachea, bronchus, lung or transmitted to other organs through blood vessels and lymphatic vessels, and may even cause chronic poisoning of the body. Organic solvents such as ethanol, isopropanol, butanol, propanol, butanone, ethyl acetate, butyl acetate, toluene and xylene are often used in printing ink. Although most of these solvents can be removed by drying, the residual solvents will migrate to food and do harm to human body. Therefore, the purchase of screen washing water and thinner should be made through formal channels. Hengjin Company solemnly promises that the purchase of screen printing thinner and screen washing water of Hengjin is in full compliance with EU standards. Be responsible for your health and society.
