提高瓦楞纸箱的防潮性能需要从哪些方面注意?

来源:http://www.gtmfpack.com 发布时间:2020-09-15

1.建议改用防水防潮效果更好的原纸,特别是起坑的瓦纸。检验原纸的防水效果如何,可通过可勃仪测试原纸的表面吸水性,一般表面吸水度在50克/平米(60S)以下时,防水防潮效果较好。通常,造纸厂为了提高原纸表面防水性,在造纸工艺中需要提高表面施胶淀粉糊液中防水助剂的比例。
1. It is suggested to use the base paper with better waterproof and moisture-proof effect, especially the tile paper with pit. In order to test the waterproof effect of base paper, the surface water absorption of base paper can be tested by the Cobb instrument. Generally, when the surface water absorption is below 50g / m2 (60s), the waterproof and moisture-proof effect is better. Generally, in order to improve the surface waterproof property of base paper, the proportion of waterproof additives in the surface sizing starch paste solution should be increased in the papermaking process.
2.在纸箱生产加工过程中,应尽量去除纸箱内的水份。原纸仓库尽量与室外隔绝,避免仓库内部空气潮湿。制糊时增加粉的含量,减少上胶量,可减少纸箱的水份。另外增加硼砂比例也会改善瓦楞纸板的手感。减少过纸天桥的纸板堆积量,放慢车速,特别是瓦楞纸板堆叠后进行充分抽湿。
2. During the production and processing of cartons, the moisture in cartons should be removed as much as possible. The base paper warehouse should be isolated from the outside as far as possible to avoid the humidity inside the warehouse. When making paste, increase the content of powder, reduce the amount of glue, can reduce the moisture of the carton. In addition, increasing the borax ratio can also improve the feel of corrugated board. Reduce the stacking amount of paperboard across the paper overpass, slow down the speed, especially fully dehumidification after stacking corrugated paperboard.
3.储存环境,下线后的纸板应该在抽掉尚未散掉的蒸气,避免温差形成凝水现象,储存纸板或纸箱的环境保持通风透气,纸板纸箱避免放在地面,采用垫板(托盘、夹板)承起。存放中注意相互间的间隙,以利于通风散热。
3. Storage environment: the off-line cardboard should be drained of the steam that has not been dispersed to avoid condensation caused by temperature difference. The environment for storing cardboard or cartons should be kept ventilated. The cardboard boxes should not be placed on the ground and should be supported by base plates (pallets and splints). Pay attention to the space between each other during storage to facilitate ventilation and heat dissipation.

4.在产品交货过程中,有的使用敞篷货车运输,有的使用厢式货车。通常后者比前者更能保护纸板纸板的干燥,避免及减少回软。
4. In the process of product delivery, some use open truck transportation, some use van. Generally, the latter can protect the drying of paperboard better than the former, avoid and reduce the softening.
5.瓦楞纸板从纸板流水线下线之后应尽快进入下道工序,周期越长,纸板发挥容易吸收空气中的水份而回软。要尽量缩短纸箱在生产加工过程中的停留时间,避免暴露在潮湿空气中的时间过长而回软。车间也应该与室外进行适度隔离,避免水汽直接吹进车间。
5. The corrugated board should enter the next process as soon as possible after it is offline from the paperboard assembly line. The longer the cycle is, the easier the paperboard will absorb the moisture in the air and return to soft. The residence time of cartons in the process of production and processing should be shortened as far as possible, so as to avoid being exposed to humid air for too long and return to soft. Water vapor should be isolated from the workshop directly.
