The single-furnace production of tempered glass and laminated glass takes only 1.5 hours, and the maximum daily output can reach 200 square meters. At the same time, it can be used with the production of glass bending clips, which can be formed in one time, or can be pre-pressed with an autoclave to help with the deep processing of many types of glass, which has solved the problem of difficult forming of bent clamps...

Overall characteristics

The forced cross-convection glass autoclave is a sealed pressure vessel with forced dual-system convection internal circulation heating. The temperature, pressure, and vacuum are effectively controlled inside. Using PID control, precise control of temperature and pressure can be achieved, so that The temperature and pressure can be changed completely according to the design curve; it is suitable for the synthesis and production of laminated glass according to various process requirements. Especially products with intermediate films made of PVB or SGP materials can ensure perfect product quality and yield.

There are six stages in the standard working process of LIJIANG Glass architectural glass autoclave equipment, which are the preheating and preprocessing stage, medium temperature and medium pressure stage, high temperature and high-pressure stage, heat preservation and pressure holding stage, pressure holding and cooling stage (graded cooling), and pressure relief stage. The entire operation process of temperature and pressure adopts a PLC-based PID control system. The temperature and pressure realize real-time online monitoring and are equipped with fully automated operating procedures and manual-automatic switching shortcut keys.

10.2. Extensible structure

There are flange interfaces reserved inside and outside each vacuum pipeline, and the number of air extraction interfaces can be expanded according to actual conditions.

11. Control system

11.1 Control system

The touch screen and PLC are all products from Siemens of Germany. They have paperless recording and data storage functions and can check the temperature and pressure changes in the kettle in real-time.

11.2 Proprietary control software

The control software with independent intellectual property rights ensures that during the process of temperature and pressure increase, temperature and pressure have interlocking control functions, which can realize the control process of temperature, pressure, pressure, etc. to ensure that temperature and pressure are synchronized according to the set process curve. and automatic temperature compensation and pressure compensation control during the constant temperature and pressure process to ensure the stability of pressure and temperature. To ensure safe operation, a safety interlock program is added to the program.

The heating and pressurizing program can only be started when the cauldron door is closed and the cauldron door is locked. When cooling water, fans, and other components fail, the heating and pressurizing program will not start. Automatic alarm, exhaust, cooling, etc. for over-temperature and over-pressure.

11.3 The software can realize data exchange, data output, process parameter storage, process parameter call, fault alarm, and other functional requirements. It can store and call 40 sets of process parameters.
