Thiết bị kiểm tra tỷ lệ rơi bột mịn của khăn giấy PN-DQT

    PN-DQT Tissue paper desquamate tester is a tissue paper powder drop rate detection instrument developed according to the national standard GB/T 20810-2018, which is suitable for roll tissue paper, flat tissue paper, jumbo tissue paper and other products. In the process of manufacturing household paper from virgin pulp, in order to achieve the purpose of better softness, manufacturers will add certain short fiber pulp, and the combination of short fibers and other long fibers is not very strong. Therefore, during use, a small amount of short fibers will escape, which is what we commonly call "paper powder". Long-term use of tissue paper with a high powder loss rate on the skin and inhalation of the respiratory tract will adversely affect human health, so it is of great significance to detect the tissue paper desquamate.
    tissue paper desquamate (%) = (pre-test quality-post-test quality) / pre-test quality * 100
    The instrument's swinging device uses a crank slider mechanism, with stable swinging frequency and precise swinging stroke. Using software timing control, the test time can be set. The clamping device is simple, convenient and practical. The powder loss rate is specified in the latest national standard GB/T 20810-2018 for Tissue paper: it must be less than or equal to 0.5%..
