產品介紹∣最小燃燒壓力裝置

特點
Features

MBP™（最小燃燒壓力裝置）用於測試在高壓條件下封閉容器中用熱絲點燃的乳化炸藥的最小燃燒壓力。MBP 是 OZM與加拿大爆炸物研究實驗室 (CERL) 合作開發的乳化炸藥先進穩定性和敏感度測試的全新方法。

MBP 是市場上首款同類型設備在提高硝酸銨炸藥的安全性方面邁出了一大步。它是一種通用、使用簡單、易於評估的解決方案，經久耐用，既適用於生產和科學實驗。

應用

雖然乳化炸藥的處理通常相當安全，但與之相關的事故仍時有發生，而傳統的穩定性或敏感度測試方法不足以發現其危險行為。經研究發現，大多數事故都是在材料的泵送、製造或運輸過程中承受高壓和高溫時發生的。因此，確定最小燃燒壓力已成為乳化炸藥最重要的安全特性之一。

MBP 主要用於測試乳化炸藥在開發和工業生產過程中的敏感度。同時，使用 MBP 進行的小規模試驗可提供有關乳化炸藥安全泵送壓力的重要資訊。另外，MBP 也可用於其它可能承受壓力和溫度負荷的爆炸物。

MBP 測量與控制單元

The MBP™ (Minimum Burning Pressure Apparatus) is used for the determination of the minimum burning pressure of emulsion explosives ignited by a hot wire in a closed vessel under high pressure conditions. The MBP is a completely new approach to advanced stability and sensitivity testing of emulsion explosives, developed in cooperation between OZM Research and the Canadian Explosives Research Laboratory (CERL). The MBP is the very first equipment of its kind on the market and it represents a huge step forward for the safety improvement of ammonium nitrate based explosives. It’s a universal, simple-to-use and easy to evaluate solution made durable for both production and scientific experiments.

APPLICATIONS
While emulsion explosives are normally quite safe for handling, accidents connected with them are still occurring and conventional methods of stability or sensitivity testing are not representative enough to discover their risky behavior. It has been found that most of the accidents happened when the materials were subjected to elevated pressures and temperatures during their pumping, manufacturing or transport. The determination of the minimum burning pressure has therefore become one of the most important safety characteristics of emulsion explosives. The MBP is primarily designed for testing sensitivity of emulsion explosives during both their development and industrial manufacture. Small-scale tests with MBP can provide very important information about the emulsion explosive safe pumping pressure. The MBP can also be used for other explosives, which are likely to be subjected to pressure and temperature loads.
