The Problems and Challenges of Mineral Cotton Board Industry
?
?? As a result of the use of starch as binder, compared with other ceiling materials, mineral wool decorative sound-absorbing panels have a significant flaw - fear of water. Inhalation of large amounts of water or a long time the case of fumigation of water vapor, mineral wool decorative sound-absorbing panels will have deformation concave, decorative performance decline. Therefore mineral wool acoustic board if you want to use in the wet southern or bathroom, bathroom and other places to use, we must solve the problem of poor moisture resistance.
???? Abandoned mineral wool acoustic board is recyclable, can be used as raw material for reproduction after crushing, so from the perspective of environmental protection and comprehensive utilization of materials, manufacturers need to bear the responsibility of the recovery of discarded mineral wool board. China's mineral wool decorative sound-absorbing panels have been developed over the past 20 years, some of the early mineral wool acoustic board has completed its historic mission, to be its recycling, but in what way recycling? And transportation costs are relatively high, how to solve the waste of mineral wool board recycling has become a new topic.
General description of mineral wool board
?
?? In China, mineral wool board industry is becoming increasingly fierce competition, Beijing Star card, the new North Dragon card, as well as Shanghai Armstrong three brands of mineral wool acoustic panels occupy more than half of China's market. China's accession to the WTO, with the tariff reduction and the introduction of a number of policies, many foreign brands have the strength to gradually enter the Chinese market. In recent years in Hebei and other provinces, many small plants have mushroomed as quickly emerged, because some small factories one-sided pursuit of profits, blindly reduce costs, the quality of the product does not attach importance to, or even illegal activities, seriously disrupting the mineral wool sound absorption Board of the market order.
?? In this context, several large companies have been a certain degree of impact in the north, increasingly competitive, pressing foreign brands step by step, there are so many domestic small factories eyeing. Large companies only in the consolidation of the existing market at the same time, is also committed to open up new markets, develop more new products and new hoisting system.
Production Process of Sound Absorption of Mineral Cotton Board
?
?Mineral wool decorative sound-absorbing panels of the production process is relatively complex, there are wet long-net acquisition, wet rotary screen, dry paste and molded plastic mold, semi-dry method, and so on, most of the current manufacturers Using wet process. My company's mineral wool acoustic board automatic production line of the introduction of Japan's advanced production technology, the use of wet long net Chaozuo forming, through the pulp, long net Chao Du, dehydration, cutting, drying, cutting, spraying, finishing And other processes to complete the whole process
