Introduction Polymethyl methacrylate (PMMA) is a chemical and synthetic transparent thermoplastic material serves as an alternative for glass formed from the methyl methacrylate polymerization. The transparent plastic material from the acrylic resin family manufacturing and processing improvement employ scientific polymerization principles and mechanisms for the productivity and quality improvements. Thus, the processing and manufacturing process does not only focus on the industry or market needs but also health, environment and the social effects. The analysis presented in this paper is helpful in understanding the definition of the PMMA and its properties. Further analysis in this paper, explores the biocompatibility and ...

Chapter 3- Experimental

3.1 Methodology

In order to produce PMMA, some steps need to be followed.

PMMA is generally made by mixing 20 cm3 of Methyl Methacrylate monomer with 0.1-0.3 g of Lauroyl peroxide initiator. It needs to be poured into a steel or glass mould and heated up by submerging the mould into a water or oil bath at 100 °C. Once the glycerine stage has been shaped, the mould is put into a cold water bath.
3.2 Source of the material
The types of material that would be used for this project is Methyl Methacrylate [monomer] and 1, 1’-AZOBIS (CYCLOHEXANECARBONITRILE) [Initiator] and Lauroyl peroxide (Luperox) [Initiator]. The materials are not ...

Wal-Mart Stores Incorporation, known better as Wal-Mart, is an American corporation The Walton family control over 50% of the retail corporation. Along all those years since its incorporation in 1969, Wal-Mart has remained as a family owned enterprise. The headquarters is situated in Bentonville, Arkansas.

Introduction

Waste management refers to the process of collecting, transporting and disposing trash, sewage and other waste materials. There are different sources of waste including residential, industrial, commercial, institutional, construction and demolition, municipal, agriculture and manufacturing and all these waste products whether solid, gaseous, liquid or radioactive come under the realm of waste management. The EU Waste Framework Directive lays down a legislative framework for the waste management and also provides a definition for waste. Article 1 of the EU Directive provides the definition of waste as "any substance or object which the holder discards, or intends to or is required to ...
