Production of Safety Laminated Glass

Film method is the main method of manufacturing laminated glass with the benefits of simple process, high yield and good product quality, and includes the major production processes of cutting into large pieces, cutting, edge grinding, powder spraying, baking and bending, powder clearing, film pulling (PVB), humidity conditioning, combining, initial lamination, high pressure lamination, etc.

The quality of safety glass depends largely on its PVB adhesive in between, which has particularly strong hygroscopicity, and is especially sensitive to the humidity of surrounding environment. When the environment humidity is greater than 35%, it will bear the problem of surface bubbles resulting in a decrease of its bonding strength with the glass. Therefore, in the production process “combining” of safety laminated glass, the environment temperature and humidity control becomes very important (18 ~ 22°C, 25 ~ 35%).

Dryer Dehumidifying and Thermostat Systems for Laminated Glass Production

Dryer dehumidifying and thermostat system adopts the imported dehumidification rotor with Swedish patent, which provides efficient and stable process guarantee. The unit adopts the latest patented technology - double-layer (inside and outside) anti-cold bridge frame structure, which not only ensures the overall equipment strength but also greatly reduces the energy loss. The system's intelligent control mode is flexible and simple; DDC or PLC controller is optional according to the customer's requirements; touch screen, configuration monitoring software, etc. are equipped as well to provide a safety guarantee for precise control. Dryer plants have advanced equipment including CNC machining centers, laser cutting and welding machines, imported foaming devices, cold bending and molding production lines, etc., and also possesses experienced design and production technicians. Rigorous procurement programs and standardized production process control makes Dryer's dehumidifying and thermostat system more perfect.

Dryer offers energy-saving installations for laminated glass production

According to the production process of laminated glass, Dryer also provides customers with more patented energy-saving products. For example, the semi-natural cooling unit, which consumes only 55-65% of the energy consumed by a typical freezer, provides a very energy efficient product and stable high temperature chilled water (16 ~ 23°C) for the cooling process of the glass from the autoclave with an accuracy of ±0.5°C.

Unlike general refrigeration units, Dryer's semi-natural cooling unit has many advantages such as advanced technology, simple operation, stable operation, easy management as well as highly controllable output precision, configurable cooling capacity according to the demand and remarkable energy-saving effect, etc. It’s especially suitable for the production process of safety glass.

It is Dryer's aim to “Create More Profits for Our Customers”. Dryer's laboratory will continue to develop new energy-saving and low-carbon products for customers in the safety glass industry, such as Dryer’s latest patented dehumidifying and thermostat unit that utilizes the waste heat from air conditioning and cooling units as a source of regenerative heat, which will be launched soon.
