Środki smarne a bezpieczeństwo żywności. Cz. 2

Sutkowski R.

Przemysł Spożywczy

2010

T. 64, nr 3

29-31

W artykule podano przykłady rozwiązań zwiększające bezpieczeństwo zdrowotne żywności. Przedstawiono informacje pomocne w doborze środków smarnych dla przemysłu spożywczego. Uwzględniono następujące warunki środowiska produkcji: niska lub wysoka temperatura, wilgotność, stężone środki agresywne (myjące), zapylenie. W artykule zamieszczono również specyficzne zastosowania środków smarnych w przemyśle spożywczym. W odniesieniu do środków smarnych przytoczono przykłady rzeczywiście obecnych w zakładach dokumentów systemu zarządzania jakości ISO 9001;2001.

The article contains the examples of solutions that ensure the necessary food safety level and the information that allows to choose the food grade lubricants. The article takes into consideration the conditions of production such as: low temperature, high temperature, humidity, concentrated aggressive substance (washing), dustiness. The study presents the law regulations concerning food grade lubricants - USDA H1. The article contains the examples of the documents existing in the plants using ISO 9001;2001 management quality systems concerning lubricants.

The development of the lubricants applied in the porous bearings

Król A., Giemza B., Kałdoński T.

Journal of KONES

2007

Vol. 14, No. 3

311-317

In the article the development process of lubricants applied to the porous sliding bearings is described and characterised. Porous bearings are widely used in mechanical vehicles, household appliances and manufacturing equipment. However their application to tribological pairs is believed to be limited because of their properties and features such as small resistance to edge and dynamic loads, ability to work only at small sliding velocity. For the last twenty years intensive research under the development of the porous bearings has been observed and newly designed porous bearings have occurred. In that process also lubricants were developed. As the result the range of used lubricants is wider and also their chemical constitution was changed from the mineral oils to the synthetic bases giving better resistance on aging process and better rheological characteristics. Each group of lubricants was characterised and the problems of lubricant selection and application were described. In the article it was also noticed that especially the Polish manufacturers of porous materials do not regard the problem of lubricant selection seriously. Finally, it was summarised that wider selection of new lubricants for the porous bearings enables proper design of the tribological pair for the future work conditions.
