A receptacle (such as a box, jar, jar) used to wrap or load an article, or a coating material forming or softening. Another Web container is a collection of interfaces between the component and the platform in the application server. The container is born with the development of the thin client system. When developing thin client systems, developers spend a lot of effort to focus on thread safety, transactions, networks, resources, and so on, thus reducing development efficiency. Since these solutions to these details are generally invariant, or only parameters are changed, from the point of view of code reuse and design patterns, developers extract these low-level details into platforms and provide a certain interface. This allows business developers to focus on the implementation of business logic without focusing on the implementation of these underlying details.Storage Containers
The container is generally located within the application server and is loaded and maintained by the application server. A container can only exist within an application server, and an application server may establish and maintain multiple containers. The container generally adheres to the configurable principle that the container's users can achieve their own usage requirements by configuring the container parameters without modifying the container's code.
1, must be stable and prevent overload. The stationary operation is mainly to load and unload slowly, and to maintain the relative stability of the load during the operation. To prevent the pressure vessel overload first is to prevent overpressure, followed by the operating temperature strictly controlled within the scope of the design. 2. Check frequently during the operation of the container. The inspection contents include process condition, equipment condition and safety device. 3, if the sudden failure, serious threat to safety, should take immediate measures to stop operation.Storage Containers
Stainless steel and carbon steel are generally used. At room temperature, pure methanol does not corrode most metals (excluding lead, magnesium, and platinum). However, the copper coating (or copper alloy), zinc (including galvanized steel) or aluminum at high temperature susceptible to methanol corrosion, at room temperature by its corrosion rate is slow. Do not use plastic containers to store methanol, because the long-term use of plastic containers will deteriorate, may lead to methanol pollution. Many resins, nylon and rubber, especially nitrile (NBR), ethylene propylene rubber, PTFE and neoprene are ideal materials for methanol processing and storage equipment.Storage Containers
