Zinkoxidis a common white powder material, which is often used as a mildew-proof agent, bactericide and anti-ultraviolet additive in coatings. It can effectively improve the weather resistance, corrosion resistance and mildew resistance of coatings, so zinc oxide is added to many indoor and outdoor walls, steel structures and wood coatings. However, although it has many advantages, there are still some side Effekter och problem som måste uppmärksammas under användning . endast genom att förstå det tydligt kan vi använda det bättre .
First, from a health perspective, zinc oxide is mostly in powder form when used as a coating raw material, and dust is easily generated during production and construction. If protective measures are not taken during spraying or mixing, such as wearing a mask or maintaining good ventilation, these fine dust particles may be inhaled into the lungs, which may irritate the respiratory tract in the long run, causing symptoms such as coughing and sore hals . Därför, när du använder eller kontaktar torrpulvermaterial som innehåller zinkoxid, rekommenderas att arbetare bär skyddsmasker och skyddsglasögon .
Secondly, from the perspective of environmental protection and construction effect, although zinc oxide is non-toxic, if it is added too much in the formula, it may affect the dispersion and adhesion of the coating, making the coating uneven, powdery, cracked, and even affecting the overall appearance and durability of the coating. Especially in some high-gloss coatings, improper addition may also lead to color instability or blekning .
Another important point is to avoid mixing with certain ingredients. If zinc oxide is mixed with certain acidic substances or unstable additives, chemical reactions may occur, affecting the storage stability of the paint and even shortening the shelf life of the paint. Therefore, when mixing the paint, it is necessary to add it scientifically according to the formula design, and it is not recommended to change the proportion of ingredients själv .
In short, zinc oxide is a very practical ingredient in paint, which can improve anti-corrosion and anti-mildew properties, but you should also pay attention to protection when using it, control the dosage, avoid excessive addition, and pay attention to compatibility with other raw materials. For ordinary household users, buying finished paint from regular brands is the safest choice, and keeping ventilation and avoiding inhalation of dust during construction is the best protection För din hälsa .
