FAQ

Currently electric heating laminator and oil heating laminator in solar industry which is more popular? What are the reasons for choosing?

Electric heating laminating machine is more than oil heating laminating machine in new production line.

Compared with the traditional oil heating laminating machine, the new electric heating laminating machine has significant advantages, which are reflected in the following points:

a. Heating method is more environmentally friendly, no environmental pollution.

b. Heating carrier (electric heating plate) directly heating steel plate, high conversion efficiency.

c. Compared with oil heating laminating machine, energy saving is more significant. Overall production costs are reduced.

In order to better compatibility, meet the production of 182mm to 210mm, or 230mm solar module, how to choose the laminator effective lamination size?

At present, the width of the laminator is 2700mm and is compatible with all types of solar modules. The length is slightly different according to the customer's own capacity demand and plant planning. Most of them are between 7000mm-10000mm, and some customized models will be longer. It can be customized according to actual requirements.

What is the process time of each glass/backsheet module and glass/glass module on the market?

Different materials (EVA/POE) have different use conditions, different parameters, and different user environments. These factors will lead to certain differences. Generally speaking, data are more common in the following range.

Glass/backsheet process time: 450S-540S; (Refers to the double chamber model, the processing time within one chamber)

Glass/glass process time: 600S-720S; (Refers to the double chamber model, the processing time within one chamber)

Is it necessary to add laminating tooling (laminated aluminum frame) for the laminating process of glass/ glass module?

There are three methods to laminate glass/ glass module, not the only way to deal with it is to add a laminating tool.

a. Tooling is set on the periphery of the module.

b. Paste the corner guard at the four corners of the module.

c. In the long and short sides of the module with tape processing on glass surface.

In the choice of vacuum pump, should choose screw pump or rotary vane pump?

Whether screw pump or vane pump, reasonable collocation can meet the needs of use.

a.Screw pump has more advantages in the treatment of gasification of EVA residual glue, and the frequency of maintenance is lower.

b.Rotary vane pump in the treatment of gasification of EVA residual glue, the vacuum pump oil needs to be replaced regularly.
