The Lifespans of Products Made with MDF

Bulletin of the Transilvania University of Brasov. Series II: Forestry • Wood Industry • Agricultural Food Engineering, 2023
The Horizon Europe funded EcoReFibre project (www.ecorefibre.eu) is concerned with recycling fibreboards and, in particular, Medium Density Fibreboard. This paper covers our research on determining the typical lifespans of products containing fibreboard. Knowing the lifespan of a product is important as it is the main determining factor that influences

Entwicklungsmöglichkeiten von MDF

Holz als Roh- und Werkstoff, 1997
In Europa begann der sturmische Aufbau von MDF-Produktionskapazitaten erst Ende der 70er Jahre, und damit im Vergleich zu den USA ca. 10 Jahre spater. Der Anteil von MDF an der deutschen Holzwerkstoffproduktion lag 1994 bei 8% und weltweit 1993 bei 6%. Bis zum Jahr 2000 wird international mit einer anhaltend dynamischen MDF-Produktion gerechnet und ihr

Kriechverhalten UF-verleimter MDF

Holz als Roh- und Werkstoff, 1992
Untersucht wurden UF-verleimte 19 mm dicke MDF verschiedener Hersteller, die sich sowohl hinsichtlich der Kurzzeiteigenschaften als auch der Formaldehydabgabepotentiale und Rohdichteprofile deutlich voneinander unterschieden. Die Dauerstanduntersuchungen, wurden nach der FESYP-Methode durchgefuhrt.

Toughening of MDF - OPC Composites

MRS Proceedings, 1990
AbstractMacro-Defect-Free (MDF) materials are cement-polymer composites exhibiting high flexural strengths and high toughness (for cement based systems). The incorporation of fibers into MDF composites has been found to offer the possibility of increasing both the ultimate flexural strength and toughness of MDF materials prepared using an ordinary ...

Macro Defect Free (MDF) Cements

European Journal of Engineering Education, 1987
SUMMARY Ordinary cement products based on calcium silicate (Portland cement) or calcium aluminate (refractory, rapid hardening cements) exhibit a number of interesting properties but are deficient in strength and toughness. The purpose of the ICI work on cements was to understand the cause of these deficiencies in order to design improved cement ...

The MDF discrimination measure: Fisher in disguise

Neural Networks, 2004
Recently, a discrimination measure for feature extraction for two-class data, called the maximum discriminating (MDF) measure (Talukder and Casasent [Neural Networks 14 (2001) 1201-1218]), was introduced. In the present paper, it is shown that the MDF discrimination measure produces exactly the same results as the classical Fisher criterion, on the ...

Untersuchungen zur gleichgewichtsfeuchte von MDF und spanplatten

Holz als Roh- und Werkstoff, 1995
EMC of different types of UF bonded MDF (P. radiata) were determined in dependence of rel. humidity between 40 and 95% and compared with that of industrial particleboards.

Toughening the Macro Defect Free (MDF) Cements

AIP Conference Proceedings, 2010
High performance polymer based‐cements (i.e. cements having a water to cement ratio, w/a, close to 0.1) almost totally free of defect, have been developed in recent years claiming a great interest for their very high tensile strength compared with traditional cements.

Macro-defect-free (MDF) cements

Journal of Thermal Analysis and Calorimetry, 2006
MDF cements using the blends of sulfoaluminate ferrite belite (SAFB) clinkers and ordinary Portland cement (OPC) in mass ratio 85:15 with Al2O3, and starch, polyphosphate (poly-P) or butylacrylate/acrylonitrile were subjected to moist atmospheres (ambient, 52 and 100% relative humidity (RH)) to investigate their moisture resistance.
