Biotransformation of poly (epsilon-caprolactone) and poly (vinyl chloride) blend
(Sociedade Brasileira de Microbiologia, 2003-11-01)
Poli épsilon-caprolactona é um importante polímero biodegradável e miscível com o PVC, um polímero sintético industrial, termo susceptível e não biodegradável. A blenda PVC/PCL é importante em propriedades mecânicas e ...
Biotreatment effects in films and blends of PVC/PCL previously treated with heat
(Brazilian Archives of Biology and Technology, 2005-03-01)
Poli épsilon-caprolactona é um importante polímero biodegradável e miscível com o PVC, um polímero sintético industrial, termo susceptível e não biodegradável. A blenda PVC/PCL é importante quanto a suas propriedades ...
Modifications on PVC films by ultrasound
(Elsevier B.V., 2002-07-01)
PVC films submitted to ultrasonic irradiation presented structural changes as probed by infrared measurements. These measurements showed some infrared bands alterations attributed to the increase concentration of some ...
Construction and demolition waste as a source of PVC for recycling
(Sage Publications Ltd, 2012-02-01)
Construction and demolition waste can contain considerable amounts of polyvinyl chloride (PVC). This paper describes a study of the recycling of PVC pipes collected from such waste materials. In a sorting facility for the ...
Conservação pós-colheita de frutos de pimentão sob diferentes condições de armazenamento e filmes
(Associação Brasileira de Horticultura, 2008-06-01)
Este trabalho teve como objetivo avaliar diferentes temperaturas e coberturas na conservação de frutos de pimentão 'Magali-R'. No primeiro experimento, avaliou-se o uso de filme de PVC ou cera, e os frutos foram armazenados ...
Hydrophilization of PVC surfaces by argon plasma immersion ion implantation
(Kluwer Academic/plenum Publ, 2003-03-01)
Commercial polyvinylchloride (PVC) sheets were treated by plasma immersion ion implantation, PIII. Samples were immersed in argon glow discharges and biased with 25 kV negative pulses. Exposure time to the bombardment ...
Migration of diethylhexyl phthalate from PVC bags into intravenous cyclosporine solutions
(Elsevier B.V., 2005-07-15)
The migration of diethylhexyl phthalate (DEHP) from PVC bags into LVPS (0.9% NaCl) and LVPS with cyclosporine at concentrations of 2.5 and 0.5 mg/ml was studied. PVC bags were placed in contact with these solutions and ...
Projeto de um sistema pneumático de cortar tubos de pvc em uma linha de produção
(Revista de Engenharia Química e Química, 2017)
The influence of soil and landfill leachate microorganisms in the degradation of PVC/PCL films cast from DMF
(Associação Brasileira de Polímeros, 2012-01-01)
While the use of plastics continues to increase in our daily lives in a growing range products, these materials are very persistent in the environment. The blending of aliphatic polyesters with other thermoplastic polymers ...
Treatment of PVC using an alternative low energy ion bombardment procedure
(Elsevier B.V., 2011-12-15)
In many applications, polymers have progressively substituted traditional materials such as ceramics, glasses, and metals. Nevertheless, the use of polymeric materials is still limited by their surface properties. Frequently, ...
