"June 1" Children's Day is approaching, the children's furniture market seized the opportunity to engage in promotional activities, attracting many parents to "sweep goods." However, the results of the random inspection of children's furniture announced by the Guangdong Quality Supervision Bureau recently are worrying: the passing rate of 62 batches of children's furniture is only 67.7%. Liao Guifu, the technical director of the furniture inspection room of the provincial quality inspection center responsible for this furniture inspection, reminded parents to pay attention: heavy metal must be used for the development of colorful panel furniture, and the harm is no less than the formaldehyde of the furniture. Therefore, try to buy children's furniture as much as possible Choose the lighter color.

According to Director Zhang of the Quality Division of the Provincial Quality Supervision Bureau, there were two batches of children's furniture with heavy metals exceeding the standard. The heavy metals in the furniture mainly include lead, cadmium and chromium. The "Sunshine Rain" brand No. 301 children's bedside table produced by Shenzhen Gangdahao Furniture Co., Ltd. has a measured value of soluble lead nearly 40 times higher than that of soluble chromium, and a measured value of nearly 13 times higher than standard. The main reason is that the production enterprises did not inspect the raw materials and used inferior paints and coatings.

The reporter visited many children's furniture markets in Guangzhou and saw that children's furniture, without exception, attracted the attention of children by their colorful colors. The reporter counted a combination cabinet full of cartoon patterns, with 11 colors. Not only that, most children's furniture is panel furniture, it is difficult to find a safer solid wood material. It is understood that a previous test showed that among the 23 samples of lead paint, orange paint had the highest lead content, followed by yellow, green, brown, etc., and these colors are precisely the most used in children's furniture.

This random inspection also found that 3 batches of children's furniture had excessive formaldehyde emission, which caused greater harm to human body, especially the impact on infants and young children. Liao Guifu said that the cause of excessive formaldehyde in furniture is one of excessive formaldehyde in the board itself, the second is the use of inferior adhesives, and the third is caused by spray paint. Formaldehyde is a volatile gas, so furniture should be ventilated for at least one month before use. When buying children's furniture at the same time, it is best to choose a small amount of adhesive. According to reporters, the environmental protection levels from low to high are: MDF, particle board, large core board, plywood, laminate, integrated wood, solid wood.

Stop Valves

Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
