Recently, the reporter visited more than 10 building materials supermarkets and building materials markets such as B&Q, JSWB, Handan, Baikang, etc., and sold waterproof coatings, adhesives, wood-based panels, wood floors, toilets, water faucets, latex paints, and woodware. Paints and other 10 categories of interior decoration products were asked and understood in order to give consumers the most complete green building materials purchase advice.
Toilet bowl check seal depth
In 2006, the shadow of the quality of toilets has not yet been dispersed, and the quality test of the Bureau of Industry and Commerce has filled it with haze. The reporter learned from the inspection results of the Bureau of Industry and Commerce that the quality of toilets in this test was mainly due to insufficient water seal depth.
Experts said that the lack of water seal depth will reduce the deodorant ability of the toilet. This is because the exhaust gas in the water channel will escape through the unqualified water seal, which will easily cause environmental pollution and be harmful to human health. Experts told reporters that the toilet water seal should be more than 50mm. In addition, the reporter reminded consumers that they must look for the “day†word mark when they purchase the toilet. I do not know whether it is to save money or save water resources.
Latex paint checking ratio
When buying latex paint, consumers all know that they must pay attention to their environmental performance, but they may ignore the contrast ratio. As everyone knows, the contrast ratio is directly related to the covering ability of latex paint, and the hiding power is directly linked to the beautification of the wall. It is understood that in the samples tested this time, the safety performance was basically acceptable, but the contrast ratio was poor.
Experts said that the contrast ratio of latex paint should not be less than 0.90, otherwise its painting function will be greatly reduced. In addition, good quality latex paint can also delay the aging of the wall, such as the subtle cracks in the wall changes, mold and so on. Experts explained that in general, the paint resistance of latex paint should reach 10,000 times. However, some of the tests did not reach 20 times. The reporter learned from the market that very few consumers are concerned about the scrub resistance of latex paints. In fact, when purchasing latex paints, pay attention to the contrast ratio and the scrub resistance index of latex paints while paying attention to the environmental performance.
Water nozzle check water saving performance
The water spout has the closest connection with the lives of ordinary people. Everyone likes to say, "Water is the source of life." However, unqualified water nozzles often cause a "source of life" to be wasted. In the Industrial and Commercial Bureau's inspection, a total of 38 samples failed, and the flow was too great for consumers to spend a lot of money.
According to industry standards, the flow rate of the outlet of the water nozzle should not exceed 0.15L/s under a dynamic pressure of 0.1 MPa. Experts also told reporters that since the flow of the water spout is difficult to see with the naked eye, it is very necessary to issue a quality inspection report at the time of purchase. In addition, the reporter saw on the market a new type of water-saving faucet that adopts vertical sealing and automatic closing technology. The faucet has a 20-second automatic shutdown, anti-drip and other functions, water-saving rate of up to 20% to 50%. At present, the major building materials city, building materials supermarkets have such taps for sale.
Wood paint inspection pests
Wood lacquer is one of the "invisible killers" of the indoor environment. In the paint often contains excess benzene and lead. Benzene has been identified by the World Health Organization as a carcinogen; lead may affect the body's nerves, hematopoiesis, digestion and other systems. The soluble lead standard value for wood coatings should not exceed 90 mg/kg, and the benzene content should not exceed 0.5%. Here, experts remind consumers that many miscellaneous brands of paint on the market are forging Chinese environmental protection signs, and consumers are often confused by them. Therefore, be sure to look for big brands at the time of purchase and purchase them in the big building materials market.
