Wellyoung acoustic perforated gypsum board is designed on the basis of helholtz resonance theorem, After perforated, the holes, board and the wall make up of many resonant cavities, when air molecules pass the holes, the resonant cavities will consume large quantities of sound energy. It is widely used in auditorium, office, cinema, hospital, school and so on. Features Light weight in unit acreage High edge rigidity Strong nail pull resistance Smooth,paintable surface NO visible joints and grid Sustainable,fully recyclable material Installs on any standard drywall suspension system Fireproof and stop burning Moisture resistance,sag resistance Specifications: Based board Knauf gypsum board or common gypsum board Thickness 12mm Size 1200*2400 Square hole 3/8.33, 5/15, 8/20, 10/20, 12/25mm Round hole 6/18.18, 6/20, 6/25, 8/18, 8/17, 8/20, 8/25, 10/20, 10/25, 12/25, 15/30mm Cross hole 6/10/20, 6/10/25, 8/12/25, 12/20/30mm Irregular hole 8/15/20 Oblong hole 4-14mm

Industry Paperboard crush cutting machine The paper board crush cutting machine is used for the end customers of corrugated box (color box), and it is used as the filling or cushioning material in the packaging in the manufacturing industry; Such as precision instruments, meters, electrical appliances, ceramics, glass, crafts, furniture and other industries. It can deal with irregular waste cardboard, unqualified cartons, color cartons and cartons, with or without printing, and can solve the thorny problems of enterprise managers. Paper products, recycling, no pollution sources; The state explicitly forbids "non degradable products" as filling materials, which can be used as substitutes for some chemical products. Paperboard expanding and cutting machine features : Green environmental protection. 2. Reduce cost. 3. Waste utilization. 4. Wide use. Paperboard expanding and cutting machine advanced technology : The paper board expanding and cutting machine uses German technology to provide you with high quality green packing and filling materials; The unique technology turns the corrugated boxes that need to be discarded into "free" soft and fluffy green packing filling materials, and is used in the transportation packaging of fragile goods; The main switch is also an emergency brake to ensure safety; This product is widely used in packaging industry, transportation industry and parts processing industry. For example, motor manufacturers use fluffy paperboard as filler to facilitate logistics transportation; Small space and easy operation; A variety of specifications to choose from, with super large production capacity. Welcome order! good price good quality !
