In the hot summer, various beverages will enter the sales peak. After drinking, how to environmentally degrade a large number of used plastic bottles has become a problem at hand. In the Jiajia Lixin Materials Technology Co., Ltd. in Xiangcheng District, the waste plastic bottles have come in handy. Through the new process, the company extracts polyester fiber from plastic bottles to make decorative art boards for sound absorption, noise reduction and heat preservation. Even some venues of the Beijing Olympic Games and Shanghai World Expo have applied this new decoration materials.
Sound absorbing decorative art wall
Yesterday, the reporter saw in the factory of Yanjiali in the Yangcheng Lake Resort in Xiangcheng District. The walls of the office seemed to be covered with a layer of dark green carpet. It felt fluffy and looked carefully. The texture was clearly visible. The tables and chairs between the lattices are light and portable, and the colors are bright. These office facilities use the polyester fiber sound-absorbing decorative art board independently developed by the company.
It is understood that the polyester fiber sound absorbing decorative art board is obtained by extracting polyester fiber from the recycled cola bottle and then pressing it by hot pressing. The specific production process is that, in the early stage, the recovered cola bottle is broken, and then granulated and spun. After the filaments are cut into short fibers, the cotton is weighed and weighed according to a certain ratio. The materials of different melting points and different colors are mixed together by the equipment, and then the fibers are combed into a uniform fiber web through the equipment, and subjected to acupuncture. The evacuated fibers are closely held together to form a fiber cotton. After the fiber cotton is heat-set, it is cooled by a cold water roll and cut into different sizes as needed.
The polyester fiber sound-absorbing decorative art board absorbs 80% of the sound, and the finished table and chair weighs only half of the wooden table and chair, and the environmental performance reaches EO. In view of its sound absorption, noise reduction, thermal insulation and other effects, this new material has been widely used in the field of architectural acoustics such as stadiums, theaters, concert halls, road sound barriers, home decoration, etc., including some venues of the Beijing Olympic Games and Shanghai World Expo. .
The general manager of the company, Zuo Hongyun, told the reporter that the polyester fiber sound-absorbing decorative art board replaced the rubber used in the production process of other furniture with low-melting fiber. During the pure physical production process, it will not release waste water and formaldehyde and other toxic and harmful substances. The material can be recycled after use, and it is more environmentally friendly than traditional thermal insulation and sound absorbing materials such as rock wool and glass wool.
At present, the polyester fiber sound-absorbing decorative art board has 15 invention patents, 26 utility model patents and 40 design patents. In October 2014, the polyester fiber sound-absorbing decorative art board won the “National Key New Product†project of the Ministry of Science and Technology. In addition, it was also certified by Oeko-Tex in Switzerland, and the products can be used in the EU countries.
Zuo Hongyun has positioned the polyester fiber sound-absorbing decorative art board as the third-generation wood-based panel, and extends the application of the art board to the field of household items such as tables, chairs, lamps, coasters, mouse pads, mattresses, and tissue boxes. Last year, the 2,000 tons of used plastic bottles recovered by the company produced the same weight of plates, with annual sales of more than 40 million yuan. In the next step, the company will proceed to break the bamboo charcoal into the material to achieve the effect of removing formaldehyde from the decorative space.
