With the improvement of people's living standards, people's awareness of environmental protection and safety and health have gradually increased. They are also increasingly concerned about the safety of interior and exterior wall paints. Here are two questions for everyone to say, what brand of latex paint is good? Is the latex paint toxic? If it is toxic, what ingredients are toxic and toxic? Please explain it in detail.
Latex paint is a water-based paint. Their film properties are much better than solvent-based coatings; while solvent-based coatings are half replaced by water. The toxicity problem of organic solvents is basically solved by latex paint, so latex paint is basically non-toxic and should be a green product. However, not all latex paints are 100% non-toxic and harmless. It is recommended that consumers try to buy large-brand latex paints in the reputable formal market or specialty stores, because the sampling rate of big brand products is higher. Relatively less toxic and safer.
Harmful substances that may be contained in inferior latex paints include formaldehyde; other organic solvents such as dichloromethane, chloroform, benzene, toluene; and heavy metals such as lead, cadmium, chromium, and mercury. Moreover, latex paint is made of chemical substances after all, therefore, it should not be in contact with the skin for a long time, and should be washed off with soapy water or wiped with a cloth in time. But even if these latex paints with harmful substances are added, the content of harmful substances is very small. As long as you pay attention to ventilation after painting and stay in the whole after drying, it will not cause too much damage to the body. Consumers don't have to talk about it at all.
Experts say that it is toxic to determine whether the latex paint is toxic, mainly because it contains the toxic components. Several major components in latex paints, such as water, pigments, emulsions, fillers, and various auxiliaries as solvents, are substantially free of substances harmful to humans. In particular, some well-known brands at home and abroad have a higher safety factor and consumers can use them with confidence. Some poor architectural coatings, of course, are called latex paints, but they use chemical raw materials such as polyvinyl alcohol and polyvinyl formal to replace the emulsion, and even use starch or the like as a binder, often because of the synthetic process. Off, contains a lot of free formaldehyde, which will cause damage.
At present, there are a few inferior water-based 196,107 coatings on the market, and the brand of “latex paint†is harmful to consumers. This inferior paint contains a lot of free formaldehyde, which is harmful to the human body. Because it has a strong irritating taste, it is easy to distinguish, please don't buy it.
How to prevent latex paint?
1. Strengthen labor protection education so that operators (including relevant personnel) can master relevant protection knowledge.
2, the workplace should have good ventilation conditions, such as poor ventilation, must take measures before painting.
3, should be equipped with the necessary protective equipment, such as masks, respirator, safety goggles or full face mask, workplace should have eyewash device, or rubber gloves (cloth gloves), overalls, sleeves, foot covers.
4. When there is paint on the hands or skin, try not to wash it with harmful solvents. Wash with kerosene or diesel oil, or scrub with soap, washing powder and wood chips, then wash with warm water.
5. Regular physical examinations are carried out for workers who have been engaged in painting for a long time, and symptoms are promptly treated.
6. Improve the operating environment. For example, red dans should be brushed as much as possible, and sprayed less to reduce the chance of droplets and gas inhaling into the human body. When operating, stand in the upwind direction, tightly seal the paint container and avoid gas. Volatile.
7. Wash hands and face before eating. If you use harmful paint for a long time, you should take a shower.
How long after the latex paint is on the wall?
After brushing the latex paint, pay attention to keeping the ventilation at home. Then you can put some plants to formaldehyde at home, such as spider plant, aloe vera, and tigertail orchid. At the same time, you can put one or two pots of saline in the room at a concentration of 5%~10%, so that the smell of formaldehyde and paint in your home can be almost eliminated in a day or two. Activated carbon can also be placed at home, and activated carbon has adsorption functions for harmful substances such as formaldehyde, benzene, toluene, ethanol, ether, kerosene, and vinyl chloride. By these methods, after the latex paint is applied, it takes about half a month to stay. But the premise is that you must buy environmentally friendly latex paint, it is recommended to choose a well-known brand of products to ensure the environmental protection of the product.
Economical Injection Masterbatches are the most common Black Masterbatch. This black masterbatches are made with recycle PE/EVA carrier, has low or middle carbon black, has calcium carbonate. It has the advantages on the prices, and universal applications for PE production, such as blowing film, injection, extrustion, molding so on.
