Application of OMRON PLC and MCGS configuring software in control system of vacuum glass production line

The mathematics model for heat flowing and transferring in vacuum glass was established by the principle of conductive and convective heat transfer,and the equations,such as vacuum glass conductive heat quantity by free molecule,solid transferring heat through the brace and the margin,exterior convection and heat transfer,were deduced.

Through the comparison between them,the result shows that energy-efficient effect of the vacuum glass windows is more obvious than the regular in the building.

A new type of building surrounding structures was put forward,which applies vacuum glazing to thermal insulating wall,thereby the insulation performance of the wall was improved greatly and the thickness of the wall was reduced obviously.

The compositions,properties and preparations of lead-free glasses such as crystal glass,electronic glass,electric vacuum glass,solder glass and solder glass-ceramics are reviewed.

Designing and development of whole glass and vacuum mushroom shape solar collector;

In order to improve the property of the present solar collector and to make use of it on a large scale, a new kind of higher efficient whole glass and vacuum turtle shell shape solar collector was studied and manufactured on the basis of design calculation which is provided according to the mathematical method of getting extreme value.
