Različne lastnosti PVC-ja je možno doseči z dodajanjem termičnih stabilizatorjev, mehčal, antioksidantov, polnil in drugih dodatkov. PVC ima s temi dodatki boljše mehanske in toplotne lastnosti. V diplomskem delu sem določevala antioksidante v 44 različnih vzorcih PVC. Metoda in kromatografski pogoji so bili že optimizirani. Uporabila sem reverznof...

Microplastics (MPs) are contaminants present in the environment. The current study evaluates the contribution of different well-established industrial sectors in Portugal regarding their release of MPs and potential contamination of the aquifers. For each type of industry, samples were collected from wastewater treatment plants (WWTP), and differen...
Polivinil klorid je izjemno razširjen termoplastični polimer, ki ga najdemo povsod okoli nas. V čistem stanju je krhek material, zato se pri proizvodnji uporabljajo različni dodatki, da postane bolj primeren za obdelavo. Skupina najpomembnejših dodatkov so mehčala, ki mu znižajo temperaturo steklastega prehoda in ga naredijo mehkejšega. V življenjs...
A new device for assessing Varroa destructor (Anderson–Truman) mite infestations in honey bee colonies was designed, tested, and evaluated against the sugar roll method, a widely used method by beekeepers. The Varroa Shaker Device (VSD) is constructed of polyvinyl chloride (PVC) pipe that separates into three parts. Inside the shaker there are two ...

The largest amount of solid waste from the textile industries is mainly derived from fabric manufacturing until the cutting stage: hard fibers (spinning waste), beaming and soft fibers (weaving yarn waste), and off-cuts (cutting process). This research aimed to (i) conduct an exploratory interview with a large Brazilian cotton textile manufacturer ...
