Let me first talk about the toxic ingredients contained in the paint.
1. VOC (containing benzene, formaldehyde, chloride, ammonia, ethylene glycol, esters and other toxic substances): VOC is a component that cannot form a volatilized film, that is, we can inhale the components in the body, if the concentration in the paint room Too large, excessive intake of the human body, can cause poisoning: headache, nausea, vomiting, fatigue, etc., convulsions in severe cases, long-term damage to the human liver, kidneys, brain and nervous system in such an environment, resulting in memory Serious consequences such as decline.
At present, the evasive measures we can take are that the ventilation of the paint room in the paint shop must be good, wear Air Purifying Activated Carbon adsorption mask, reduce the VOC concentration in the paint room, minimize the amount of human inhalation, VOC is insoluble in water, can only be adsorbed by activated carbon, there are many steam The manufacturer introduced the water curtain spray booth, which is purely a scam.
2. TDI (toluene diisocyanate): a synthetic component of the curing agent; toxic. Excessive TDI beyond the standard will cause harm to the human body, mainly sensitization and stimulation, eye pain, tearing, conjunctival congestion, cough, chest tightness, shortness of breath, asthma, red papules, maculopapular rash, contact allergies and other symptoms. There is a possibility of carcinogenesis. Irritating.
Regular routine avoidance measures: wear chemical safety glasses, wear anti-poisoning infiltration overalls, wear rubber and oil resistant gloves. It is also a flammable and explosive product, avoiding open flames and prohibiting smoking. This ingredient is soluble in water and can be rinsed with plenty of water if not in contact with the skin or into the eyes.
3. Formaldehyde: The main hazard of formaldehyde is the stimulating effect on the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people have discomfort. Mainly manifested as conjunctival congestion, redness, difficulty breathing, heavy breathing, hoarse throat, speech or dry dull or wet. Poisoners can also feel their breathing sounds bold. Another specific manifestation of mild formaldehyde poisoning is one to two degrees of sore throat edema.
Moderate poisoning: coughing, coughing, chest tightness, difficulty breathing, and dry and wet breaks. When the chest X-ray is used, the lung texture is substantive, and it is transformed into scattered little spots or flaky shadows, which is the medical model of bronchial pneumonia; the throat edema is increased to the third level. Blood gas analysis is accompanied by mild to moderate hypoxemia.
In this environment for a long time, it affects the respiratory system, the reproductive system (fetal malformation), and is highly likely to cause cancer.
Circumvention measures: Keep the amount of paint in the paint room during construction, reduce the concentration of formaldehyde, and wear an activated carbon adsorption mask.
