Blow Moulding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube until it takes the shape of a Mould cavity. This method is particularly effective for creating products with consistent wall thickness and complex shapes. Developed in the mid-20th century, blow Moulding has become an integral part of many industries, including automotive, packaging, and agriculture. In agriculture, the process has seen significant advancements and is used for making various products, such as containers for pesticides, irrigation equipment, and even large tanks. This blog will explore the blow Moulding technique, its current practices, applications in agriculture, and future perspectives. Blow Moulding Technique: Process and Variants The blow Moulding process involves several steps: 1. Parison Formation: A plastic tube, called a parison, is extruded. The parison is then pl...
Polymeric Chemical Reaction Polymer can be further classified by the type of chemical reactions which the monomers undergo in producing molecular weight compounds. 1. Poly condensation reaction –Monomers react by repeated splitting off H2O, NH3, CH2O, NaCl, or other small molecules on a step by step reaction to build of the molecular size. 2. Addition reaction – occurs among molecules containing double or triple bonds or with oxo-ring compounds. No small molecules are liberated and reaction is the rapid chain type. A. Poly condensations Reactions. a. Representative groups ...
