鋯化表面處理工序可以清除鋼板表面的油污和雜質。●引進了改善水質的RO設備。●鋼桶的外面和內面都經過磷酸鐵表面化學處理。
磷酸鐵化學處理促使鋼桶內的清潔度大幅提高，對提高鋼桶外面和內面涂膜的附著力以及耐繡性都有很大的幫助。
Surface treatment facilities ensure the cleanliness of the steel drums. ●RO equipments were installed to improve the quality of water. ●Both internal and external surfaces of the drums are iron-phosphating treated.
The cleanliness of the internal surface of the drum is enhanced, as well as the adhesion and durability of the external surface.
RTO廢棄處理系統(tǒng)：系統(tǒng)預防和控制污染，節(jié)約自然資源，提高能源利用，減少廢氣處置，持續(xù)改進環(huán)境績效。
RTO waste disposal system: The system prevents and controls pollution, saves natural resources, improves energy use, reduces waste gas disposal, and continuously improves environmental per formance.

3重7層卷邊工藝使天地板和桶身充分地結為一體，卷邊部具有較高的耐沖擊性，大大的規(guī)避了萬一從高處跌落時鋼桶泄露的風險。
Triple-seaming: Top, bottom, and body of a drum are integrated strongly by a triple- seam-er. The triple-seaming makes it possible that edges of top, bottom and body of a drum arerolled in perfect seven layers, which greatly increases resistance against external shock. As aconsequence, the triple-seaming effectively avoids the risk of breakage should drums drop fffrom high positions.

氦氣測漏原理：將注有氦氣的密封鋼桶放入真空罩內，即可檢測出滲漏氦氣的鋼桶。
氦氣測漏的優(yōu)點：●可以檢測出大于30微米的針孔 ●氦氣和鋼桶內的內容物不發(fā)生化學反應 ●檢測時對鋼桶沒有任何損傷
Mechanism of Helium leaktester: A drum flled with helium gas will be placed inside of a vacuumcham-ber and detected by the leak-sensor if helium gas leaking fromthe drum
Advantages of Helium leaktester: ●The helium leaktester is able to detect and fnd leak of 30μmo ●No chemical reaction effects contents in the drums ●A total inspection can be caried out without amages to inspected drums

UN是聯(lián)合國海事組織制定的國際海運危險貨物規(guī)則：用于出口危險貨物包裝，需要使用帶UN鋼印的鋼桶。只有沖軋了UN鋼印的鋼桶才被允許用于危險物品出口。統(tǒng)仕實業(yè)的UN認證鋼桶通過了以下試驗。
UN certificate is recommended by United Nation for marine transportation of dangerous articles. Marine transportation of dangerous articles insteel drums require UN marked containers. In China,only UN certifcated drums are permittedto fill and transport dangerous articles if viaocean. UN certifcated drums manufactured by Tongshi industry passed two tests asfollows.
