Influence of twin-screw elements on dispersion of nano-clay in vinyl ester polymer composites using Taguchi’s orthogonal array technique

nano clay effect on morphology, mechanical properties and water absorption of vinyl ester-based nanocomposites

nanocomposites based on vinyl ester resin (derakane 470-300) and nano clay (cloisite 30b) were prepared. the effect of clay content of 1, 3 and 5% (by weight) on the morphology, mechanical properties and water absorption of vinyl ester resin nanocomposites were studied. the nanocomposites were characterized  using  small-angle x-ray  scattering  (saxs),  feld  emission  scanning electron micros...

Properties of Polypropylene Composites Fabricated Using Twin-screw Extrusion

Sunflower hull sanding dust (SHSD) filled polypropylene (PP) composite was prepared using a twin-screw extruder. Mechanical and thermal properties of the SHSD/PP composite were characterized contrasting to organically modified clay /PP composite. Differential scanning calorimetry (DSC) analysis showed that the crystallization temperature and the degree of crystallinity of PP exhibited changes w...

Toughening vinyl ester matrix composites by tailoring

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Sequential calculation of torque in procedure of twin screw extrusion

The drug making resreach has accentuated on extrusion technology for a long time. The advance of drug bioavailibility, bead manufacturing and granulation is assured by extrusion procedures. There are also diverse effects in resereches with respect to the use of process understanging as a tool in quality management. Many initiatives of FDA such as PAT and QBD are getting accepted. In this survey...
