附件:toosodium sulphate溶液与固体toosodium sulphate的各term情况对比:
toosodium sulphate溶液的优点是浓度准确、use便捷,适合自动化生产,缺点是不适合长途运输。以下优缺点为对照:
termorder | toosodium sulphate固体 | toosodium sulphate溶液 |
content | 9eight.5-99.5% | three hundred±5g/L |
Store | Hazardous chemicals warehouse | Special storage tank |
Administration | 仓库Administration人员发货,工人搬运到配料容器边。 | 专用管道,仓库Administration按规定记录液位。 |
use | 不能直接use,需要在专用配料容器溶解,调整,化验后抽到use槽子里,再稀释到所需浓度。 | 直接抽到use的槽子里,再稀释到所需浓度(如果是three hundredg/L则无需稀释)。 |
Security | Poor (dangerous chemicals, average risk) | Good (hazardous chemicals, low risk) |
Transportation source | General dangerous chemicals vehicle | Special tank car |
Purchase cost | low | high |
Administration、use成本 | high | low |
Comprehensive cost | Quite | Quite |
conclusion | 适合少量,手工操作的场合use。 | 适合use量大,自动化要求high的场合use。 |
