Recently, the toxic incidents of steel-wood doors have been raging, in order to release consumers' doubts, and interviewed the vice president of the Steel and Wooden Door Committee of the National Federation of Industry and Commerce Furniture and Decoration Industry Association, Yongkang Xin, for the steel door materials and safety mentioned in the post. De Mechanical and Electrical Co., Ltd. Baifu Linmen
Mr. Chen Deren, Chairman of the Board of Directors.
Material environmental protection PVC has long been used
Steel-wood doors are a rising star in China's door industry. It is environmentally friendly, energy-saving, beautiful and durable. Therefore, when the author mentioned the toxic incident of the steel-wood door on the Internet, Chen Deren was quite surprised: "The steel door is poisoned. The wood is pure."
However, materials, steel plates are more commonly used industrial materials, how can it be toxic?"
As for the toxic PVC (polyvinyl chloride) material mentioned in the post, Vice President Chen said that PVC has been eliminated in the early years. It is understood that PVC will add stabilizers during production. Stabilizers are toxic and non-toxic, but only add toxic substances such as lead salts.
Stabilizers can cause hidden dangers. Nowadays, the national standard plastic profiles are all UPVC (unplasticized polyvinyl chloride) standards. The so-called unplasticized means that no plasticizer is added.
High temperature process quality inspection is strict
"At present, steel-wood doors are the most environmentally friendly products, and neither materials nor production processes are toxic." Chen Deren said with confidence.
It is understood that the steel wood door manufacturing process must undergo cutting steel plate, surface treatment, plastic powder coloring, baking varnish, baking wood, high temperature printing and other links. Chen Deren pointed out that the entire series of processes, only paint contains traces of formaldehyde, and can be volatilized at high temperatures
. At this stage, the paint on the surface of the steel door is usually made of resin paint and is realized by a high temperature of 200 to 300 degrees. The formaldehyde is basically volatilized during the production process and does not cause harmful effects on the human body.
Chen Deren also introduced that the quality inspection of steel doors has been very strict. The steel-wood door enterprise shall send the sample of the door to the quality inspection center for testing, and the quality inspection center shall record it, and the test result will be allowed to enter the market. In addition, the quality inspection center
Sampling inspections of steel-wood doors will also be conducted on a regular or irregular basis.

The standardized production of wooden door products promotes the management level and product quality of steel-wood doors related enterprises, and further promotes the development of China's steel-wood door industry.
