Enhancing its water resistance is critical for broadening its applications, especially in humid and outdoor environments. This study investigates the enhancement of MDF water resistance through the chemical modification of the constituent wood fibres (in this case, thermo-mechanical pulp or TMP) through periodate oxidation. The treatment with sodium metaperiodate results in the formation of dialdehyde fibres (DA-TMP) which are then spray-coated with a phenol-formaldehyde resin, following the industrial procedures, and converted into a MDF through proper hot pressing. Comprehensive evaluation of the physical, mechanical, and biological properties is conducted, along with the study of fire behaviour comparing boards made from both oxidized and non-oxidized fibres. The results reveal that periodate oxidation reduces water absorption by 54% and thickness swelling by 56%, indicating significant changes in the fibres’ chemistry and morphology. Despite a slight decrease in mechanical properties, the overall performance of DA-TMP based MDF confirms this as a promising method for achieving superior durability in moisture-prone environments, including outdoor constructions. Importantly, the biological resistance of the material remains unaffected by the oxidation of the fibres, ensuring continued protection against biological attack and long-term durability. Additionally, fire performance tests show that DA-TMP based MDF exhibit reduced peak heat release and smoke production, further enhancing their suitability for fire-sensitive applications. Consequently, this research contributes to expand the use and durability of wood-based materials across various industrial sectors, offering a sustainable and effective alternative to traditional moisture resistance treatments.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00107-025-02325-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Virgin pine and secondary fibres were studied for their size distributions and morphological features. MDF panels were fabricated by substituting virgin fibres with secondary fibres at 15% and 25% rates, with additional 100% recycled MDF produced using ST-obtained fibres. Secondary fibres from both waste sources were shorter and had more fines than virgin fibres. For recycled MDF incorporating ST fibres, a notable drop in internal bond strength was observed when using fibres from post-consumer fibreboard waste, while modulus of rupture, modulus of elasticity, thickness swelling, and water absorption remained consistent. Increasing substitution rates from 15 to 25% resulted in an insignificant change in the aforementioned physical and mechanical properties. However, MDF produced with 100% recycled fibres exhibited a dramatic decrease in physical and mechanical properties, despite a reduction in formaldehyde content. Compared to MDF with virgin fibres, the internal bond strength of recycled MDF statistically decreased at all substitution ratios. In contrast, other properties were comparable at 15% or 25% rates for fibres produced using the mTMP process.

Subsequently, alternative species, such as <i>P. elliottii</i> and <i>P. taeda</i> were established for veneer production. The wood properties of <i>P. elliottii</i> and <i>P. taeda</i> are inherently different from <i>P. patula</i> and limited knowledge is available on the optimal processing parameters for these species. This study examined how log size (diameter class), storage duration and steaming time impact the veneer quality of <i>P. elliottii</i> and <i>P. taeda.</i> Wet recovery, peeler waste production, dryer throughput and quality recovery were determined and the results show significant differences in wet recovery between the two pine species. This was mostly caused by differences in taper, as <i>P. taeda</i> logs show more taper than <i>P. elliotti</i>. Extended log storage negatively affected wet recovery for both species as fungal induced blue stain was often mistaken for wane, leading to the unnecessary rounding of logs during the rotary peeling process. Logs stored for longer duration resulted in lower veneer grades after drying compared to those processed within four weeks after felling. Log steaming improved peeling performance, enhancing veneer quality without directly affecting wet recovery. Increasing steaming time from 8 to 12 h did not clearly impact wet recovery, but significantly improved veneer quality after drying. Larger logs (mostly from the pruned section of the tree) generally achieved better veneer grades due to fewer knots, while longer-stored logs resulted in more downgrades due to fungal induced blue stain and splitting, likely from moisture loss. <i>P. taeda</i> showed overall better quality recovery than <i>P. elliotti</i>, however, <i>P. elliottii</i> had better volume recovery.

Air and kiln-dried sideboards were used to extract different low molecular compounds from the surface layer, assess the moisture content, and conduct a mould test. Principal component analysis revealed the grouping of the drying types. This was confirmed by partial least-squares discriminant analysis, which allowed the sideboard characteristics of the two wood drying types to be described. An outlier was detected among the air-dried observations. The collected data show more intensive mould growth on kiln-dried Scots pine sideboards than on air-dried ones. Higher amounts of total lipophilic compounds, phenols and inorganic components were found on the kiln-dried sideboard surface. Also, surface extractives from kiln-dried sideboards contained higher amount of almost all analysed fatty and resin acids, except for the oleic acid, which was more prevalent on the air-dried sideboard surface. Low-molecular-weight sugars, namely glucose, saccharose and fructose, were present in significant amounts on the surface of the kiln-dried sideboards.
