Diseño y construcción del sistema óptimo para la micro pulverización de bentonita sódica en la Empresa "MINMETEC"
(2009-06)
This project is about design and assembles of an optimal system of micro-pulverization of sodium bentonite. It is giving a description of the process to obtaining sodium bentonite. Also the physical and chemical characteristics ...
Comparison of PBM and ANPM models for predicting grinding product size distributions
(Universidad EAFITIngeniería de ProcesosEscuela de Ingeniería. Departamento de Ingeniería ProcesosMedellín, 2020)
Grinding is a very important industrial operation that draws up to 4% of the global electricity consumption. It is imperative to predict accurately the appropriate retention times necessary for a given size reduction to ...
Análise da influência do empacotamento dos agregados na porosidade do concreto
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2014-09-09)
The resistance to external actions which the concrete element is subject is related to the porosity of concrete. One of the factors that interfere in resistance is the water / cement ratio, where the higher the water / ...
Analysis of solid blends milling using population balances
(Universidad EAFITIngeniería de ProcesosEscuela de Ingeniería. Departamento de Ingeniería ProcesosMedellín, 2019)
Particle size distribution (PSD) is a key factor in size reduction processes. These processes are widely used worldwide and in the Colombian industry. However, they represent a high energy consumption process, which requires ...
Esferas rígidas en una trampa armónica unidimensional
(2018-04-10)
En este trabajo se intenta presentar un marco teórico que permita la descripción de un sistema unidimensional compuesto por pocas partículas interactuantes mediante un potencial de esferas rígidas atrapadas en una trampa ...
Caracterização de material compósito reforçado com partículas ferromagnéticas
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia MecânicaUTFPR, 2018-12-03)
The aim of this work was to develop and characterize a particulate composite with magnetic properties for the application of an electromagnetic actuator for vibration control. The composite development was focused on the ...
Síntese e caracterização de nanolátices poliméricos para aplicação em fibras têxteis
(Universidade Federal do Rio Grande do NorteBrasilUFRNQuímica Bacharelado, 2018-12)
The use of nanolatex has received attention in recent years in the textile area,
due to its properties, such as a smaller particle size, transparency, high surface area,
and consequently high adsorption power, high ...
Nanopartículas coloidais de ouro e platina produzidas por ablação a laser de pulsos nano e picossegundo - efeitos de size quenching induzidos por íons e pH
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia QuímicaEngenharia QuímicaUTFPR, 2016-11-11)
Nanoparticles produced by laser ablation of solids in liquid environment (PLAL) have been proposed as an alternative to the nanoparticles produced by chemical synthesis routes. By this method, nanoparticles are synthesized ...
Micropartículas sólidas lipídicas: estudo de variáveis operacionais e encapsulação de vitamina D3
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de AlimentosDepartamento de Engenharia e Tecnologia de AlimentosEngenharia de AlimentosUTFPR, 2014-08-07)
Solid lipid microparticles can be readily obtained by the hot dispersion method. A lipid (solid at room temperature) is melted and dispersed in a stabilizer aqueous solution yielding lipid droplets suspended in water. Upon ...
Avaliação da presença de microplásticos em esgoto sanitário do município de Campo Mourão – PR
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de AmbientalEngenharia AmbientalUTFPR, 2019-12-06)
Since its discovery, plastic is increasingly inserted in people's daily lives in different aspects, presenting different sizes and colors of the most diverse. Authors define that microplastics are particles smaller than 5 ...
