Exergetic analysis of a continuous Bi-axially Oriented Polypropylene (BOPP) film unit in a plastic processing plant

This paper deals with an exergy analysis of the stretching process of bi-axially oriented polypropylene films using a hot oil coiler along with stretching and crystallising unit. Exergy destructions and efficiencies in each of the system components are calculated, while the exergy loss and flow diagram (the so-called Grassmann diagram) is presented for the transverse direction (TD) unit. The ...

Plastic Recycling Process

Plastic recycling is the process of recovering scrap or waste plastics and reprocessing the material into useful products, sometimes completely different in form from their Plastic Recycling Process original state. For instance, this could mean melting down soft drink bottles and then casting them as plastic chairs and tables. Typically a plastic is not recycled into the same type of plastic, ...

Nanoindentation characterisation of GaN films and Se nanotubes

Mechanical properties of GaN films and Se nanotubes were measured by nanoindentation tests. The GaN films were grown epitaxially on cplane sapphire substrate by MOCVD technique, while Se nanotubes were readily produced by the dismutation of Na2SeSO3. The effect of penetration depth and tip shape on the mechanical properties was studied and discussed according to the elastic–plastic behaviours and ...

Plastic Production

Plastic Production PLASTIC PRODUCTION Plastics, to maintain the ideal quality, usually require a relative low humidity for the dehumidifier plastic processing in the manufacture. Most plastic is supplied as dry materials, only a small part of plastic is humid. Many kinds of plastic, i.e. PET, Nylon, ABS, Acrylic, Polyurethane, PC, PBT, are in some way hygroscopic (attracts water vapor). So ...

How to identify the quality of non-woven bags

Visually, it is impossible to distinguish whether it is brand new or ordinary. In order to save costs, many businesses will treat ordinary materials as new materials for customers to process environmentally friendly non-woven bags. Secondly, in order to be able to distinguish whether it is brand new from the non-woven fabric, we can feel the type of fabric from the feel. Nowadays, ordinary ...
