In recent years, the use of sprayed materials in home and commercial decoration has become increasingly common. However, many decorators lack proper safety knowledge, leading to a growing number of incidents involving fires, explosions, and poisoning. According to reports, more than 400 cases of paint poisoning caused by indoor wall coatings occur annually in China. Over 15,000 people are poisoned each year, and more than 200 lose their lives. These numbers continue to rise, making paint-related health risks a major concern for both the public and authorities.
Many liquid materials used in painting, such as solvents and thinners, release harmful vapors that can be inhaled or absorbed through the skin. Prolonged exposure to these gases can damage vital organs and disrupt normal body functions. Some chemicals may cause skin irritation, including rashes, eczema, and dryness when they come into contact with the skin.
The maximum allowable concentration of benzene in residential areas is 0.8 mg/m³, while in industrial workplaces it is set at 5 mg/m³. Exceeding these limits can lead to serious health issues. To prevent paint poisoning, it's essential to take proactive measures.
First, workers should receive comprehensive safety training to understand how to protect themselves properly. Second, ensure that the workspace is well-ventilated. If ventilation is inadequate, additional precautions must be taken before starting any painting work. Third, always wear appropriate protective gear, such as masks, respirators, safety goggles, or full-face masks. It’s also important to have eyewash stations, rubber gloves, overalls, and protective clothing available.
If paint gets on your hands or skin, avoid using harsh solvents for cleaning. Instead, use kerosene, diesel, or wash with soap, washing powder, and wood chips, followed by a rinse with warm water. Workers who are exposed to paint regularly should undergo regular medical check-ups to detect and treat any symptoms early.
Improving the working environment is another key step. For example, try to brush paint instead of spraying it whenever possible to reduce the risk of inhaling droplets or fumes. When working, stand upwind to avoid breathing in toxic vapors, and make sure paint containers are tightly sealed to minimize evaporation.
Before eating or taking a break, always wash your hands and face. If you work with harmful paints for extended periods, showering after work is highly recommended. Applying a protective paste to your hands and exposed skin can also help. This homemade paste consists of talc powder (22.1%), starch (4.1%), vegetable or mineral oil (9.4%), gelatin (1.9%), glycerin (1.4%), boric acid (1.9%), and water (59.2%). Apply it after washing your hands, let it dry completely, and remove it with water and soap at the end of the day.
By following these eight simple yet effective steps, most paint poisoning incidents can be prevented. Safety should always come first when working with potentially hazardous materials like paint and solvents.
Sandwich Panel
What are the methods for judging the pros and cons of sandwich panel?
The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?
check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.
Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.
Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.
certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.
Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
