Phenomenon 1: The barrel paint is "clean"
In recent years, as consumers pay more and more attention to the environmental protection of home building materials, the coatings market has also set off an “environmental protection windâ€. Many merchants are rushing to launch “net odor†coatings, and “clean†the products they sell. ", "Green" words. However, when the reporter visited, he found that almost no sales staff explained clearly what was “net flavor†paint?
"The net taste product is completely tasteless, very environmentally friendly", "the clean taste technology does not add flavor, can quickly remove the indoor odor", "the net taste is only relative, the paint is completely odorless is impossible"...... In an exception, the sales staff of several paint shops in the Blue King House Dazhongsi store almost all use the explanations of this kind to answer what is “net tasteâ€. When the reporter mentioned whether it is possible to look at the relevant quality or environmental testing report, the sales staff played the "Tai Chi" again, and they all took "the test report at the head office, we are not there for the time being", "our products are qualified" or "We are big brands, all products placed on the cabinet are environmentally friendly, and the quality can be completely assured."
expert's point
Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center, said in an interview that at present, the country has not yet established a unified standard for paint odor, and there is no special standard and requirement for "net taste". "Net taste" is only a manufacturer. Proposed sales concept. Yan Ming, general manager of Digu Rila (Beijing) Coatings Co., Ltd. also said that some merchants speculate on environmental protection concepts through hints, word games, etc., and even exaggerate the environmental protection of products.
According to Song Guangsheng, "net taste" paint mainly refers to special effect functional paints that can purify the odor and toxicity in the air. The paint itself is almost non-toxic. However, the "net taste" coatings produced by many small manufacturers do not have the net taste function, but the smell is small. At present, most of the products on the market belong to the two kinds of pure taste principles of “emulsion technology directly eliminates odor†and “fragrance covers emulsion odorâ€. The former is a true net taste technology, and the latter is a pseudo-clean taste technology. When consumers buy paint, they can open the product on site to test it. The good clean taste product should have no irritating taste. If there is obvious irritating smell or other fragrance, it may be added flavor or The “pseudo-net taste†products of harmful substances also cause harm to the human body and the environment.
Phenomenon 2: I don't know what VOC is.
Recently, the industry has continuously exposed the excess formaldehyde in coatings. First, in August, the Beijing Municipal Administration of Industry and Commerce released the quality monitoring results of interior decoration materials, and some of the latex paint free formaldehyde projects failed. Subsequently, the Guangdong Provincial Quality Supervision Bureau also released the results of quality supervision and inspection of internal and external wall coating products, and 13 batches of products were unqualified, mainly due to excessive formaldehyde. What is free formaldehyde? What harm does it have? "The free formaldehyde index of the coating product is directly related to the content of VOC in the coating. VOC is the abbreviation of volatile organic compound, and its value refers to the coating per liter. The content of volatile organic compounds such as formaldehyde and benzene. The lower the VOC content, the more environmentally friendly the coating. If the VOC content of the coating product is too high, the free formaldehyde produced will be seriously exceeded, causing indoor air pollution. In this environment, it is easy to cause chronic respiratory diseases," Song Guangsheng explained.
However, the reporter visited and found that most consumers do not understand what VOC is. “I usually only choose the paint according to the brand's popularity, but also the VOC content in the product information? What is VOC?†For the VOC content in the reporter's mouth, the consumer Ms. Zou looked blank. Coincidentally, for how to measure whether the paint is environmentally friendly, Mr. Guo is not clear: "When it is not discernible, choose a high price, and hope to buy a reassurance."
expert's point
Ren Changqing, secretary general of the China Building Decoration Materials Association, said that the harm caused by VOC to people is slow and not easy to be detected in the short term. However, when the VOC reaches a certain concentration, people may have symptoms such as headache, nausea, and weakness of the limbs. In severe cases, they may cause convulsions and coma. Therefore, consumers must pay attention to the VOC content of the paint when purchasing. According to Ren Changqing, the national mandatory standards stipulate that the VOC content of interior latex paint should not exceed 200 g/l. However, for some brand sales personnel claiming that “the VOC content of the product is close to zeroâ€, Ren Changqing suggested that when the VOC content in the paint is less than 1 gram or tends to zero, it is internationally known as “zero VOCâ€. Therefore, if the merchant claims that the VOC content of his product is lower than the national standard, it should be supported by the test report of the authoritative organization. Otherwise, this statement is not credible.
Phenomenon 3: Water-based paint is not good
It is well known that some volatile impurities contained in paints have a volatilization time of up to 10 years. In contrast, water-based coatings are environmentally friendly, odorless, non-flammable, non-explosive, etc., and are low volatile organic content coatings. However, according to industry insiders, there are not many companies that have water-based paint production lines on the market. Some companies have switched back to selling traditional oil-based paints after selling them for several years.
In addition, the reporter visited and found that the price of water-based paint products is about 500 yuan higher than the price of traditional oil-based paint products. Due to the high price of waterborne coatings, most consumers lack sufficient knowledge and understanding of such products, and can only be discouraged. “I don’t know what water-based paints are, I’m worried about its environmental friendliness, and the price is quite expensive. I still prefer traditional oil-based paints,†Ms. Fan said.
expert's point
Sun Lianying, chairman of the China Coatings Industry Association, said that traditional coatings have long been one of the important sources of home improvement. At present, most of the coatings on the market in China still use organic solvents as solvents and diluents. Organic solvents are extremely harmful to the environment and people's health. In contrast, water-based paints can replace water with organic solvents and can be diluted directly with water. Construction tools can also be washed with water, reducing environmental pollution.
"At present, there are many water-based paint products on the market, but due to consumer consumption habits and price factors for a long time, whether it is production or sales, oil paints in China have always occupied an absolute strong position. With the emphasis on environmental protection by consumers, water-based coatings have begun to be accepted and recognized by more high-end consumer groups, but for the larger middle and low consumer markets, it is still the world of oil-based coatings.†Sun Lianying also analyzed because At present, the coating effect of most domestic waterborne coating products can not fully reach the same level as oily coatings, and the coating process of waterborne coatings is greatly affected by climate and environment, and the construction period is long. Therefore, waterborne coatings are still difficult in China. Really occupy the market. Sun Lianying said that water-based coatings are difficult to be widely accepted in the domestic market if the upgrade of product quality is not achieved.
