Depending on the method of future manifold glass units heating, the vacuum lamination furnaces may be divided into 4 types:
• Convectional heating furnace – blanks heating is carried out at the account of the heat, given up by the heat transfer agent – air, circulating in the furnace. There are two options: with forced and natural circulation.
• Radiation heating furnaces (IR) – there is applied for vacuum bag with the unit of future laminate the powerful flow of infrared radiation.
• Contact heating furnaces – there is applied for blanks heating the uniformly distributed along the entire surface of vacuum bag base electrical heater or massive steel plate heated by circulating in its channels heat transfer agent.
• Combined type – combination of several heating methods. Usually, it is the combination of radiation and convectional methods.
Examples of various types of vacuum lamination furnaces:
Laminated glass – is two or more glass sheets bonded together with the help of a special polymer composition.
Such glass is also called protective as in most cases it is used at glazing of objects with special requirements for safety. The main peculiarity of the Triplex is its incredible mechanical strength and impact resistance. Even in case of destruction of the laminated structure, the glasses do not fly apart, but stay bonded to the film. This reduces any possibility of injuries to minimum.
Laminated glass production includes two main stages – preparation of future laminate unit for baking and the process of baking till the finished product state.
