Description

Technical Field

[0001] This utility model relates to the technical field of UV conformal coating spraying machines, and in particular to a UV conformal coating spraying machine. Background Technology

[0002] UV conformal coatings possess excellent resistance to high and low temperatures. After curing, they form a transparent protective film with good properties such as moisture resistance, mildew resistance, salt spray resistance, leakage prevention, dust resistance, corrosion resistance, and aging resistance. UV conformal coatings allow products to be used in varying environments, protecting circuit boards from damage, increasing safety, and ensuring service life. However, UV conformal coatings often contain volatile organic compounds (VOCs). These substances are released into the air during spraying and drying. Long-term inhalation of these harmful gases may cause respiratory irritation, leading to symptoms such as coughing and asthma. Direct skin contact may cause allergic reactions such as redness, swelling, and itching. Therefore, there is an urgent need to provide a UV conformal coating spraying machine to solve these problems.
