1、建議使用防水防潮效果較好的原紙，尤其是帶坑的瓦紙。為了測試原紙的防水效果，可以用柯布測試儀測試原紙的表面吸水率。一般當(dāng)表面吸水率于50 g/m2 (60S)時，防水防潮效果更好。一般為了提高原紙表面的耐水性，造紙廠需要增加表面施膠淀粉糊中防水添加劑的比例。
1. It is suggested to use base paper with good waterproof and moisture-proof effect, especially tile paper with pit. In order to test the waterproof effect of the base paper, the surface water absorption of the base paper can be tested by the Cobb tester. Generally, when the surface water absorption is less than 50 g / m2 (60s), the waterproof and moisture-proof effect is better. Generally, in order to improve the water resistance of base paper surface, paper mills need to increase the proportion of waterproof additives in surface sizing starch paste.
2、在紙箱的生產(chǎn)加工過程中，盡量去除紙箱中的水分。原紙倉庫應(yīng)盡可能與室外隔離，以避免倉庫內(nèi)潮濕的空氣。做糊時，增加粉的含量，減少膠的用量，可以減少0、10-10、020的水分。此外，增加硼砂的比例也會改善瓦楞紙箱的手感。減少紙?zhí)鞓蛏隙逊e的紙板量，減緩速度，尤其是對堆積后的瓦楞紙箱進行充分。
2. In the production and processing of the carton, try to remove the moisture in the carton. The base paper warehouse should be isolated from the outside as far as possible to avoid humid air in the warehouse. When making paste, increasing the content of powder and reducing the amount of glue can reduce the water content of 0, 10-10 and 020. In addition, increasing the proportion of borax will also improve the handle of corrugated boxes. Reduce the amount of paperboard piled up on the paper overpass, slow down the speed, especially fully dehumidify the stacked corrugated boxes.

3、儲存環(huán)境:紙板滾出生產(chǎn)線后，應(yīng)將未分散的蒸汽抽走，以避免溫差造成冷凝。紙板或紙箱的儲存環(huán)境應(yīng)通風(fēng)。紙板紙箱不要放在地上，要用墊板(托盤、夾板)支撐。儲存時注意它們之間的間隙，以便通風(fēng)散熱。
3. Storage environment: after the paperboard is rolled out of the production line, the undivided steam should be removed to avoid condensation caused by temperature difference. The storage environment of paperboard or carton should be ventilated. Cardboard boxes should not be placed on the ground, but should be supported by backing plates (pallets, splints). Pay attention to the gap between them for ventilation and heat dissipation.
4、在產(chǎn)品交付過程中，有的采用敞車運輸，有的采用廂式貨車運輸。一般來說，后者比前者更能保護紙板的干燥，避免和減少軟化。
4. In the process of product delivery, some are transported by gondola cars, some by Van trucks. Generally speaking, the latter can protect the drying of paperboard better than the former, avoid and reduce softening.
5、瓦楞紙箱從紙板生產(chǎn)線上滾下后，應(yīng)盡快進入下一道工序。周期越長，就越容易吸收空氣中的水分，使其軟化。生產(chǎn)加工過程中盡量縮短紙箱的停留時間，避免長時間暴露在潮濕空氣中而變軟。車間還應(yīng)與室外適度隔離，以避免水蒸氣直接吹進車間。
5. After the corrugated box is rolled down from the paperboard production line, it should enter the next process as soon as possible. The longer the cycle, the easier it is to absorb moisture in the air and soften it. In the process of production and processing, the residence time of cartons should be shortened as far as possible to avoid softening due to long-time exposure to humid air. The workshop should also be properly isolated from the outside to avoid water vapor blowing directly into the workshop.
