1.stainless steel bars
不锈钢型材
2.Acid artificial perspiration solution
酸洗
Prepare by dissolving 0.5g of L-histidine hydrochloride monohydrate,5 g of sodium chloride and
2.2 g of sodium dihydrogen-phosphate dihydrate into water and by adding approximately 15 ml of 0.1 mol/L sodium hydroxide solution and water to this solution to make the total volume approximately 1 L of pH 5.5
向水中加入0.5g一水组氨酸盐酸盐、0.5g氯化钠,2.2g二水磷酸二氢纳,再加入约15ml 0.1mol/L的氢氧化钠溶液配制pH=5.5的溶液约1L。
4.after finishing the treatment , remove the composite specimen from the perspiration tester, separate the standard adjacent fabrics from the specimen so as to be in contact with one side at the seam in figure 2 or to be completely cut off and dry them at a temperature not exceeding 60 C
处理完毕,擦掉试验机上的残留物,用标准膜布隔开并保证其按图2所示紧贴着缝,也可以在60°c以下将其完全除去并烘干。
5.it may be confirmed by load , in this case, the load of approximately 50 N shall be applied to the specimen measuring 10cm*4cm and approximately 45N to the specimen measuring 6 cm*6cm
这可以通过负载来证实,50N左右的负载约对应10x4cm标样,45N约对应6x6cm的标样。 |
