（1）輥壓排氣法：
(1) the rolling and exhaust method:
合好的玻璃經過預熱進入輥壓機，經中空玻璃設備道輥擠壓后，進入恒溫箱，再經第二道輥擠壓，排氣、封邊完成此過程。出第二道輥后，夾層玻璃四周應呈現一整圈透明帶將邊部封好，避免高壓釜內氣體回流產生汽泡。其它部位可以有分布均勻的不透明部分存在。此工藝要求玻璃表面溫度必須嚴格控制，既不可溫度太高，使封邊過早，內部氣體無法排出；又不可溫度太低，封邊不完全，產生回流汽泡。
The closed glass enters the roller press through preheating. After the first roll of the hollow glass equipment, it is squeezed into the thermostat and then squeezed through second rolls, and the process is completed by the exhaust and the edge. After second rolls, the whole glass should be surrounded by a transparent belt to seal the edges so as to avoid the backflow of bubbles in the autoclave. Other parts can be distributed evenly and opaque. This process requires that the glass surface temperature must be strictly controlled, not too high temperature, so that the sealing edge is too early, the internal gas can not be discharged; and the temperature is not too low, the sealing edge is not complete, producing reflux bubble.
合好的玻璃預熱后表面溫度<span>20－25℃左右，中空玻璃設備道膠輥間隙應比夾層玻璃總厚度小1MM左右，壓力為0.2–0.5MPA左右。第二道膠輥間隙應比夾層玻璃總厚度小2MM左右，壓力為0.4–0.6MPA左右。

The surface temperature of the combined glass is about <span>20 - 25, and the gap between the first roll of the hollow glass equipment should be about 1MM smaller than the total thickness of the laminated glass, and the pressure is 0.2&ndash and 0.5MPA. The gap between the second cots should be about 2MM smaller than the total thickness of the sandwich glass, and the pressure is 0.4&ndash and 0.6MPA.

入第二道輥時玻璃表面溫度一定要嚴格控制在60―80℃左右。生產時首先準備好所需加工的玻璃制品，盡可能連續、不間斷地進行生產，避免因間隔時間長，恒溫箱溫度變化過劇，造成玻璃表面溫度無法準確控制。
When entering second rolls, the surface temperature of glass must be strictly controlled at 60 to 80 degrees Celsius. The production of glass products needed to be processed is first prepared in production, as long as possible, continuous and continuous production, avoiding long interval and temperature change of the thermostat, which can not control the temperature of the glass surface accurately.
輥壓排氣法的優點：可連續生產，產量高，節約能源。
The advantages of rolling exhaust method are continuous production, high yield and energy saving.
（2）真空減壓排氣法
(2) vacuum decompression exhaust method
將合片好的玻璃放入真空袋內或四周套上真空膠圈，加熱至<span>80-100攝氏度，經冷抽、熱抽，利用壓差將玻璃／PVB中間膜界面中的空氣排出并封邊。如果溫度、真空度、時間不夠，由于排氣不夠及玻璃與膠片貼合不夠緊密，易造成氣泡，或易在煮沸實驗時起泡。
Put the good glass into the vacuum bag or around the vacuum ring, heat to <span>80-100 degrees Celsius, cold pumping, hot pumping, the use of pressure difference in glass / PVB middle film interface air discharge and sealing edge. If the temperature, vacuum and time are not enough, because the exhaust is not enough and the glass is not tight enough with the film, it is easy to cause bubbles or easy to froth in boiling experiments.
中空玻璃設備小編建議：減壓真空度為650MMHG以上，冷抽溫度為25℃左右，冷抽時間20分鐘以上；熱抽時玻璃表面溫度需達到70―120℃，時間在40分鐘以上。
It is suggested that the vacuum vacuum degree is above 650MMHG, the cold pumping temperature is about 25 C, and the cold pumping time is more than 20 minutes. The temperature of glass surface should be 70 to 120 C when hot pumping, and the time is more than 40 minutes.
采用真空減壓排氣法生產具有復雜輪廓的玻璃，質量較好，但這種小批量生產方法需要手工操作。
The vacuum relief exhaust method is used to produce glass with complicated profile. The quality is better, but this small batch production method needs manual operation.
