The proposed solution for sorting wood chips helps to solve a number of urgent problems crucial to log processing. Intellectualization of sorting operations not only minimizes wood residues, but also enables the maintenance of equipment. Modifications in the chipping system, namely laser sensors and a microcontroller, help operators detect debarking defects and perform the cutting tool wear monitoring. The results of the study show that a control system intellectualization allows an efficient use of equipment and thereby serves to improve production efficiency. This study primarily concentrates on coniferous logs. The technology developed in this study is applicable to log processing equipment and can be used in debarking machines at other mills.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1857981","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45090436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The following properties were determined: stress-wave velocity of stems in radial direction, cell length, basic density, shrinkage, dynamic Young’s modulus, modulus of elasticity, modulus of rupture, absorbed energy in impact bending, and compressive strength parallel to grain. All examined wood properties increased from pith to bark. The boundary between core and outer wood determined by a 1.0% annual increment of cell lengths was well matched with that determined by radial variations of wood properties. Significant differences were found between the core and outer wood in several wood properties. Based on the results, it is concluded that when the wood of B. platyphylla is utilised as an industrial raw material, the presence of core and outer wood should be considered.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1861733","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46253499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Down-milling process compared to up-milling process produced better surface roughness, lower noise level, and flow chip. Better surface roughness (R a value) was produced by the router bits with higher helix angle compared to lower helix angle. Noise level decreased with increasing in the helix angle of the router bits. The increasing in the angle of the wood grain would increase the values of surface roughness and noise level. With increasing helix angle of the bits the amount of spiral and flow chips increased and granule chips were reduced. The investigations have clearly confirmed that the helical edge is considered to be a valuable design to improve upon the performance of the straight edge for wood milling applications.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1844851","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46705234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The constructed autoclave is capable of creating shock waves either by an electrical pulse breakdown of a spark gap arrangement or by electromagnetic actuators. The penetration depths of the fir wood test samples were measured using light microscopy, SEM and micro-computed tomography. Our results showed that by varying the intensity of the incident shock wave, the distance between the shock wave generating device and the test sample, and/or the orientation of test sample in relation to the shockwave, the wood tissue structure had been heavily disintegrated or hardly affected at all.

The effect of varying amounts of tobacco particles (4, 8 and 12%) in the glue-mixes on shear strength, wood failure and subterranean termite (Microcerotermes losbañosensis) resistance of the plywood was examined. An increase in shear strength and wood failure up to 8% tobacco particles loading was observed compared with plywood that used commercial glue formulation. Based on shear strength and wood failure, panels containing 4–8% tobacco particles would pass the requirements of PNS ISO 12466-2.

Thus, tobacco particles can be considered as a more beneficial alternative glue-mix additive in plywood production.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2020-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1830347","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46841369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monte Carlo simulation was performed for the possible range of nett returns and to identify the effect of stochastic variables on profitability. The simulation results showed positive nett return from both biomass production and processing of pellets. The sweetgum yield, market price of biomass and pellet, and projected volume of pellets had the greatest positive effect on profitability.

The low temperature (γ peak) was seen at −115°C to −83°C, differing between species and with frequency. β peaks relating to hemicellulose relaxations in association with water molecules were observed, at two locations for Scots pine and three locations in hardwoods. The α peak for lignin lay outside the temperature range studied.
