Energetice Science 公司生产的一种可以测量一定范围内二氧化碳浓度的灵敏工业空气分析器,长期以来,是被栓在或捆扎到一块胶合板上装运,它继而安置在一个再粘结的聚氨脂泡沫塑料衬垫上,于是产生一个三层壁瓦楞内合和一个瓦楞外合。一层聚苯乙烯粒子给它涂上保护层,纸合自包装开始后至加封花20到25分钟,所有这些仅花10美 A sensitive industrial air analyzer made by Energetice Science that measures the concentration of carbon dioxide in a range has long been tied or bundled onto a piece of plywood for shipment, which in turn is housed in a rebond polyurethane foam The liner then creates a three-wall corrugated joint and a corrugated outer joint. A layer of polystyrene particles is coated with a protective layer of paper, which takes 20 to 25 minutes from the beginning of the package until it is sealed, all of which only cost 10 US dollars
