As the final pressing and forming equipment for producing laminated safety glass, the autoclave boasts high yield rates, excellent product quality, and other advantages, making it an essential and indispensable piece of production equipment in the field of photovoltaic module encapsulation.

1. The autoclave’s outer shell is made of standard aluminum alloy, and the top cover can be pulled backward for convenient maintenance. The control panel is equipped with a digital temperature display, voltmeter, tachometer, control switches, adjustment knobs, and other instruments to facilitate operator control.

2. Electrical Principle: The electronic components of the hybrid control circuit are mounted on a single circuit board, featuring a dual closed-loop control system. It offers stable speed accuracy, high speed regulation precision, and strong anti-interference capability, along with comprehensive protection functions such as speed limiting and flow‑rate monitoring. By adjusting the “speed control” knob, the DC voltage supplied to the DC motor can be varied, thereby changing the motor’s rotational speed and achieving precise control of the mixing rate.

3. The heating circuit employs a solid-state relay (commonly referred to as a voltage‑regulating module) for power regulation, simplifying the circuitry. Heating power can be adjusted simply by turning the “voltage‑regulation” knob. Additionally, the control section of the heating circuit is equipped with an intelligent digital display, allowing the heating temperature to be set and adjusted freely according to the autoclave’s process requirements. All external wiring passes through a waterproof connector on the rear panel via internal terminal blocks within the controller.

Autoclave

　　As the photovoltaic industry continues to evolve, the functions of PV modules have expanded beyond mere power generation, taking on an increasing array of new capabilities. In particular, in building-integrated photovoltaics, PV modules are often designed to serve as wall panels, roofing materials, transparent skylights, or shading roofs. Conventional PV modules encapsulated with tempered glass and materials such as EVA and TPT can no longer meet these demands. Consequently, the trend is shifting toward double‑glazed laminated PV modules that employ large‑area tempered glass combined with PVB, crystalline silicon cells, thin‑film cells, and other materials. Building on this foundation, a wide variety of building‑material‑integrated PV modules will continue to emerge, becoming key targets for research and development among numerous module manufacturers. As the final pressure‑forming equipment used in the production of laminated safety glass, the autoclave—boasting high yield rates, excellent product quality, and superior performance—has become an essential and indispensable piece of manufacturing equipment in this field.

　　The autoclave consists of a vessel, a door, a circulation fan, a heater, a cooler, an electrical control cabinet, and other components, and is essential equipment for manufacturing PVB‑laminated glass. Through a control system that regulates both temperature and pressure, the device can execute three distinct phases: heating and pressurizing, holding at pressure, and cooling and depressurizing—processes that closely align with the material properties of PVB. By employing this equipment to produce photovoltaic modules tailored for building‑integrated photovoltaics, it not only addresses the aforementioned challenges and enhances product quality and yield but also enables large‑scale, multi‑specification production, thereby reducing manufacturing costs.

1. Before turning on the current switch on the console, set both the stirring switch and the speed‑adjustment/heating switch to zero.

2. Before charging, rinse the inner walls of the autoclave and the stirring and sealing surfaces with the mother liquor, then carefully close the lid to avoid impact on the sealing surfaces.

3. When screws must be seated on the valve seat, tighten them in a cross‑symmetric sequence using a torque wrench to prevent uneven stress. Do not fully tighten the screws in one go; instead, tighten them gradually and symmetrically.

4. After tightening the screw, first evacuate the reactor with a mechanical pump, then purge it repeatedly with nitrogen 2–4 times to remove air; follow with another evacuation, introduce hydrogen, start the agitator, apply heat, and proceed to normal operation.

5. After the reaction is complete, stop stirring, vent any residual hydrogen gas from the reactor, then purge with nitrogen, vent again, and unscrew the valve to take a sample.

6. The 5 L hydrogenation reactor is not resistant to strong acids; the addition of hydrochloric acid, sulfuric acid, nitric acid, or other strong acids to the reaction mixture is prohibited. 7. Sparks are prohibited near the high-pressure hydrogenation autoclave, and studded shoes must not be worn.
