英语翻译
1.Specialty Grades:The grades listed below are producedand tradedin carload and truckload quantities throughout the United States,and because of certain characteristics (i.e.,the presence of wet strength,poly coatings,plastic,foil,carbon paper,hot melt glue),are not included inthe regular grades of paper stock.However,it is recognized that many mills have special equipment and are able to utilize large quantities of these grades.Since many paper mills around the world do use these specialty grades,they are being listed with appropriate grade numbers for easy reference.The Paper Stock Industries Chapter of ISRI is not establishing specific specifications,which would refer to such factors as the type of wet strength agent used,the percentage of wax,the amount of polycoating,whether it is on top of or under the printing,etc.The specification for each grade should be determined between Buyer and Seller,and it is recommended that purchase be made based on sample.These specialty grades are as follows:
10—S Printed and/or Unprinted Bleached Sulphate Containing Foil
15—S Contaminated Bag Scrap
16—S Insoluble Glued Free Sheet Paper and/or Board (IGS)
17—S White Wet Strength Scrap
18—S Brown Wet Strength Scrap
19—S Printed and/or Colored Wet Strength Scrap
23—S Flyleaf Shavings Containing Hot Melt Glue
35—S Sorted Colored Ledger

1、特制品等级：下列等级的纸品产自美国各地,以整车为单位进行批量交易.因为这些纸品具有某些特性（即湿强度[见注释①],聚氨脂涂层,塑料,薄膜,复写纸,热熔胶）,因此不被列入常规纸品等级中.但有一点是公认的：很多工厂有特殊设备可以大批量处理这些纸品.鉴于世界各地的许多造纸厂确实使用这些特制品等级,因此这里也把它们以适当的级别数字列出来以供参考.ISRI《纸品工业篇》中,关于下列这些因素,尚未建立具体规范：所使用的湿增强剂[见注释②]类型；蜡含量的百分比,聚氨脂涂层总量（无论在印刷字表面还是下面）等.各等级的规范应由买卖双方共同确定,并建议在看过样品的基础上购买.这些特殊的等级如下：
10- S 印刷/非印刷品,经漂白,含硫酸盐薄膜
15- S 已经污染的废料袋
16- S 非可溶性胶合纸/板材（IGS）
17 白色湿强度废料
18- S 棕色湿强度废料
19- S 印刷/印染过的湿强度废料
23- S 含热熔胶的衬页边角料
35- S 已分捡的印染横板
※注释：
①湿强度（wet strength ）：纸和纤维制品浸渍在水中规定时间后,在润湿状态下测得的机械强度,国际标准以N/m表示
②湿增强剂（wet strength agent）：指增加纸张湿强度所用的化学助剂.通常情况下,在不添加助剂时,纸张被润湿后其强度仅为干燥时强度的5%～10%.
