PrinterThe main components of the ink and thinner used in the printer (dot matrix) are methyl ethyl ketone (also known as methyl ethyl ketone) or acetone, and a small amount of alcohol. Butanone and acetone are chemically similar. Butanone: a colorless liquid. The melting point is -86.3 ° C, the boiling point is 79.6 ° C, and the relative density is 0.8054 (20 / 4 ° C). It is soluble in about 4 times of water and soluble in organic solvents such as ethanol and ether. It forms a constant boiling point mixture with water (containing 88.7% of methyl ethyl ketone) and has a boiling point of 73.4 °C. Steam and air can form an explosive mixture with an explosion limit of 2.0% to 12.0% by volume. The chemical properties are similar to those of acetone.
Printer cleaning agent hazard:
Routes of entry: inhalation, ingestion, percutaneous absorption.
Health hazard: Irritating to eyes, nose, throat and mucous membranes. Prolonged contact can cause dermatitis.
Work for a long time in the air of the higher concentration of the printer's thinner volatilized, there is physical discomfort, you should seek medical attention immediately.
Alcohol-based additive printers are less harmful, but such printers are rare.
For the time being, I have not found out how much the harm caused by the additives and cleaning liquid of the printer are so long. It is hard to say that this work has been done for too long. The friends who have been engaged in such work for more than ten years are quite good, and no abnormalities are found.Work for a long time in the air of the higher concentration of the printer's thinner volatilized, there is physical discomfort, you should seek medical attention immediately. Usually pay more attention to ventilation and prevent entrances, eyes, etc.
Ink, additives, and cleaning agents have environmental labels on them. They only indicate that they do not contain harmful substances such as heavy metals.
Let's talk about safety in personal protection:
Inhalation: If the vapor concentration is unknown or exceeds the exposure limit, wear a suitable respirator.
Skin: Gloves, overalls and work shoes should be used if required. The appropriate material is butyl rubber. Safety showers and eye wash devices are available in the immediate working area.
Eyes: Wear chemical splash glasses and wear a mask if necessary.
