This part of ISO 8226 specifies a method for the determination of the hygroexpansivity of paper and board when subjected to a change in the relative humidity with which it is in equilibrium from (33 ± 2) % to (84 ± 2) %. The purpose of this part of ISO 8226 is to cover applications of paper and board intended to be used in high humidity conditions, e.g. as found in tropical countries. It may also be useful in determining the effect of excessive moisture to which paper may be subjected for short periods during some printing processes, e.g. offset printing. This method is applicable to paper and board generally. It is not, however, suitable for crêpe papers and corrugated fibreboard.
根据研究资料的分析,相对湿度从40%上升到60%,抗压强度下降的幅度最大,达到17%;其次是相对湿度80%至90%区间,抗压强度下降了10%;下降幅度最小的是60%至80%区间,为7%[3]。因此,可以看出,瓦楞纸箱周围的湿度越大,抗压强度的损失也就越大。 ...
一、仓库储存条件及堆放方法:(1)仪器仪表必须放在干燥、通风的封闭式仓库,环境温湿度不得有剧烈变化,最好能控制在5~30℃之间,相对湿度在70%以下;(2)库内不得有腐蚀性气体存在,不允许有任何化学物品和酸性物质存在;(3)仓库如采用红外线灯泡保温的话,红外线灯泡的光柱不应与仪器仪表设备接近直接照射。...
