O QUE SIGNIFICA MOLECULAR SIEVE EM INGLÊS
Peneira Molecular
Uma peneira molecular é um material com orifícios muito pequenos de tamanho preciso e uniforme. Esses buracos são pequenos o suficiente para bloquear grandes moléculas, permitindo que pequenas moléculas passem. Muitas peneiras moleculares são usadas como dessecantes. Alguns exemplos incluem carvão ativado e gel de sílica. O diâmetro de uma peneira molecular é medido em Angstroms ou nanômetros. A conversão da unidade para 1 Å é de 0,1 nm. De acordo com a notação IUPAC, os materiais microporosos têm diâmetros dos poros inferiores a 2 nm e os materiais macroporosos têm diâmetros dos poros superiores a 50 nm; a categoria mesoporosa fica no meio com diâmetros de poros entre 2 e 50 nm.
definição de molecular sieve no dicionário inglês
A definição de peneira molecular no dicionário é um material que pode absorver grandes quantidades de certos compostos enquanto não absorve outros e, portanto, é adequado para uso na separação de misturas.
