Laminated Glass is a type of safety glass consist of two more glasses stick together with an interlayer consisting of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) between its 2 layers. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces.. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass. The PVB or the EVA are sandwiched by the glass, which is either passed through a series of rollers, or vacuum bagging systems, and ovens, or autoclaves, to expel any air pockets. Then it is heated to form the initial melting. These constructions are then heated under pressure in an autoclave or oven, to achieve the final bounded product
Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered and also for architectural applications.
Baisc Structure of a Laminated Glass.
- Top layer: Glass
- Interlayer: Transparent thermoplastic materials (TPU or PVB, EVA)
- Interlayer: LED (light emitting diodes)on transparent conductive Polymer
- Interlayer: Transparent thermoplastic materials (TPU or PVB, EVA) or transparent thermoset material (EVA)
- Bottom layer: Glass
Benefits of Using Laminated Glass.
Being that it is a durable and versatile glazing material, laminated glass provides better protection against UV rays. Laminated glass serves as a guard for delicate plants, fabrics, carpets and furniture from fading.
The most important benefit of laminated glass is the security aspect of the product, but what makes this material unique are the other aspects of how the glass can be utilized to improve the environment in which we live.
Using heat and light stable pigments there is an unlimited color range when combined with tinted glass and coatings. Using colored laminated glass can brighten up any work area or section off different areas of an office all the while being very easy to maintain.
A unit operation is a physical step in an individual chemical engineering process. Unit operations (such as crystallization, filtration, drying and evaporation) are used to prepare reactants, purifying and separating its products, recycling unspent reactants, and controlling energy transfer in reactors. On the other hand, a unit process is the chemical equivalent of a unit operation. Along with unit operations, unit processes constitute a process operation.
