| 木塑加工 Wood plastic processing 聚合物中可以加入一些人工沸石，这种铝硅酸盐分子捕捉粉体可以吸收材料中的异味。通过粉体中大量的结晶空洞，吸附剂可以捕捉产生异味的有机小分子。分子捕捉吸附剂已经成功应用于聚烯烃挤出管材、注射和挤出吹塑的器皿、隔绝包装材料，挤出外包装和密封材料。分子吸附粉体还可以作为除湿剂加入塑料中以除去其中的水气。 Some artificial zeolites can be added into the polymer, and the aluminosilicate molecular trapping powder can absorb the peculiar smell in the material. By means of a large number of crystalline voids in the powder, the adsorbent can catch small organic molecules that produce odors. Molecular capture adsorbents have been successfully applied to polyolefin extrusion pipes, injecting and extrusion blow molding utensils, isolating packaging materials, extruding outer packaging and sealing materials. Molecular adsorbent powder can also be used as a dehumidifier in the plastic to remove water vapor. 不同尺寸和形状的挤出制品增加了木塑复合材料的多样性。 Different sizes and shapes of extruded products increase the diversity of wood plastic composites. 当型材不要求具有连续片形结构或者是部件具有复杂的结构设计，木塑型材可以是通过注射成型或者是模压成型。加工者有时要面对木塑材料在加工过程中如何完全充模的问题，为了解决这个问题，他们需要减少木质填料的用量以增加熔体的流动性。 When the profiles do not require continuous sheet structure or complex structural design of parts, wood plastic profiles can be molded by injection or molding. In order to solve this problem, they need to reduce the amount of wood packing to increase the fluidity of the melt. 由于200° C是木塑复合材料加工操作温度的上限，一些熔点超过200C的树脂，如PET，就不能用于木塑复合材料。 Because 200 degree C is the upper limit of the operation temperature of wood plastic composites, some resins with melting point exceeding 200C, such as PET, can not be used in wood plastic composites. 水气会劣化复合材料的性能而且还有助于孳生微生物，因此在使用木填料之前一定要先除去水气。加工成型之前木填料的要进行干燥处理，一般要求处理后的水气含量要低于1~2%。 Water vapor will deteriorate the properties of composite materials and help to breed microorganisms. Therefore, water vapor must be removed before using wood packing. Before processing, the wood packing must be dried. Generally, the moisture content of the treated wood should be lower than 1~2%. 木塑复合材料加工机械要求配有喂料设备、干燥设备、挤出设备和成型设备，还有一些必要的下游设备如冷却水箱、牵引设备和切割设备等。 Wood plastic composite processing machinery requires feeding equipment, drying equipment, extrusion equipment and molding equipment, as well as some necessary downstream equipment such as cooling water tank, traction equipment and cutting equipment. |
