margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (1)子棉中的杂质含量大,会使清理工艺复杂化,增加排杂时的落棉量,且影响产品质量和使用价值。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (2)子棉中各种病虫害形成的僵瓣棉,其纤维较短、强力很弱、成熟度很差,如不排除,会增加皮棉含绒率,影响皮棉色泽,降低皮棉品级。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (3)子棉中的绳索、布片、麻袋等粗大杂质,易堵塞机器间隙或缠绕在旋转部件上,影响机器正常运转,加速机件的磨损,缩短机器的使用寿命。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (4)砖石块、金属块等粗硬杂质,与运转部件发生碰撞,易损坏机件,增加机物料消耗,还易产生火星,造成火灾,严重影响安全生产。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 如上所述,子棉中的杂质对轧花工艺有着严重的危害,必须进行清理。<br style="max-inline-size: 100%; margin: 0px; padding: 0px;

子棉清理设备的除杂效能,是指清理机械对杂质的清除能力。各种清除设备的清杂效能不同,这是设备本身的特性所决定的,对不同类型的杂质,机器的清杂效能也不一样,设备对外附杂质的清杂效能一般较高,对不孕子等纤维性杂质的清杂能力较差。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 清理设备的清杂效能是被清除杂质量占原子棉含杂质量的百分比表示的,其计算公式为:</span></p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; font-size: 14px; text-align: center;
