Modeling and Analysis of Film Blowing process

AbstractThe manufacture of plastic bags (HDPE, LDPE, LLDPE) is one of the leadingindustries in the world and has a strong consumer demand for packaging andpackaging. The research examined the design of the film machine by analyzing themodel of the bag blowing machine. Since the emergence of the rough and theformation of the balloon focus on the cooling area when the formation of theballoon and to make the roll to be ready for the stage of cutting (finished product). ...

Single Pot Green Synthesis, Characterization And Antimicrobial Studies Of Silver Nanoparticles Using Tropical Medicinal Plant Extracts

Research on the single pot green synthesis of silver nanoparticles (AgNPs) was done using aqueous medicinal plant extract of Tithonia diversifolia and Acalypha wilkesiana. Characterization was carried out by spectroscopic techniques. Experimental optimization studies and the antimicrobial activity of the nanoparticles were investigated. Bottom-up approach was applied for the synthesis of both Tithonia diversifolia silver nanoparticles (TD-AgNPs) and Acalypha wilkesia silver nanoparticles...

Studies of Some Mechanical Properties of Watermelon Rind/Pawpaw Reel Reinforced Polyethlene Composites

ABSTRACT Some mechanical properties of water melon rind and pawpaw peel reinforced Low density polyethylene (LDPE) and Linear Low Density, (LLDPE) composites have been studied. Two sets of filler loaded LDPE and LLDPE composites were prepared using the injection moulding techniques at a processing temperature of 1900C Dispersing agent, silicon oil, was added to the composite as a plasticizer to improve flow, processabil...

Extruding Characteristics of FUTO Fabricated Extruder

ABSTRACT Optimum working condition for the FUTO fabricated extruder was established. The effect of screw speed on the viscoelastic property (die swell), sensory characteristic (hardness) and mechanical properties (modulus, ultimate strength and %elongation at break) of NNPC Polyolefin blends (HDPE/PP) were investigated. Screw speed had no effect on the mechanical properties of the unblended samples. Lower speed was found to fa...

Effects of Some Printing Variables on the Colour Yield of Reactive Dye Printed Cotton Fabric

ABSTRACT This thesis presents the findings of the investigation on the effects of some printing variables on the colour yield of reactive dye printed cotton fabric. The main print variables investigated are squeegee strokes, print paste viscosity, paste storage time and superimposed print. The printing pastes, (pastes A, B and C) used in this work were prepared using cassava starch, NaCl, NaOH and Procion reactive dye (Procion M); and were of dif...
