Black cardboard, neutral black cardboard, duplex single black cardboard 180-600G molding, 650G or more processed compound, commonly used in frame backplane, gift boxes and other single through the heart of black cardboard 200-600G molding, 650G processed through the heart of the above composite-sided black cardboard 200-500G molding, 550G or more processed wood pulp and paperboard 80-450G whole complex forming, 500G or more processed composite acoustic black cardboard: 0.7-1MM forming horn speaker pads dedicated 5mm ultra thick black paper / pasting black cardboard, 5mm super thick black cardboard packaging standards: a, paperback paper packaging: packaging material: 120g kraft paper lamination packaging: wooden pallets packing, height 1.0mm-1.5mm b, roll packaging: packaging materials: 100g kraft paper three conventional packaging: 3 inches core tube diameter: 1.0 Composition: 50% of conifer pulp and 40% hardwood pulp, 10 foreign waste. PH: extracting cold test (Independent test conditions) in scientific research organizations 7.0-7.3 thickness: 100gsm = 0.12mm (± 5%) bulk density: 0.72-0.76gsm burst index: 2.60-2.88kPa / g ring crush compression Index: 7.1-8.7Nm / g (maximum torque / g) surface of the absorbent Gross: 55-60gsm smoothness: 9-15S Production: 18,000 tons / year extension processing: a professional pasting processing line 23 (pasting machine, flat press, dryer, hot press, condensate press, trimmer combined into a production line) can be produced 600 grams -7000 grams of the product according to customer needs, pasting processing capacity of 40 tons per day ; the same time with an embossed pattern and size of the conventional size 787 * 1092mm / 889 * 1194mm, stock reel width (sealing of) 25 ~ 51inch, can cut the size according to customer demand. II. The thickness refers to the thickness of cardboard between the two sides by a certain amount of surface pressure (measured when the pressures of ± 0.1kg) direct measurement of thickness in millimeters or micrometers. White paper thickness standard 100g = 0.12mm, this The same standard applies to black cardboard thickness, double-gray, gray thickness single standard 100g = 0.155mm. III. . On Water refers to the water content within the cardboard fiber. By% according to GB standard single gray cardboard paper, double-gray paper 250g ~ 750g Moisture 7% to 9% of the composite double-gray boards of 8% to 14% of the composite duplex board 8 % to 14% of the composite whole gray plate 8% to 12% of the composite duplex board 8% to 12% V. skewness known as the founder of skewness, it is the maximum deviation of flat paper diagonal general use mm representation, as required by the skew can not exceed 3mm. VI. interlayer adhesion layer binding force between the mean bond strength by external damage when wet paper between layers of cardboard fibers with J / m represents Inter general gray cardboard layer binding force should be ≥120. 5mm super thick black paper / pasting black cardboard, 5mm thick black super jams Tel: 13712104330 Wang QQ: 191294683
