This study aimed to investigate the characteristics of screw driving torques in heat-treated Anatolian black pine and sessile oak wood. The wood samples were subjected to heat under atmospheric pressure at three different temperatures (130, 180 and 230 °C) and two different exposure time levels (2 and 8 h). Screw driving torques of seating and stri...

Effects of heat treatment parameters on the physical properties, mechanical properties, and crystallinity index of Scots pine and beech wood were investigated. Scots pine (Pinus sylvestris L.) and beech (Fagus orientalis Lipsky) sapwood samples were prepared in 2 cm × 2 cm × 36 cm dimensions by considering the physical and mechanical tests. The sam...

The aim of this study is to determine the visual deterioration, scratch resistance, surface roughness and color changes of laminate flooring against the effect of disinfection products. For this purpose, hand and surface disinfectants and cologne were applied to the laminate flooring surfaces obtained from the market in two different effect times (...

Hardness, surface roughness, and adhesion strength were determined for water-based opaque paints applied to heat-treated wood material surfaces. For this purpose, Scotch pine (Pinus sylvestris L.) and beech (Fagus orientalis Lipsky) woods were used as experimental material. Specimens were subjected to heat treatment at 3 different temperatures (150...

Background: The aim of this study is to determine the surface roughness and adhesion strength of water-based varnishes modified with nanoparticles of zinc oxide (ZnO) and hollow ceramic spherical (HCS) against accelerated UV aging effect in some ThermoWood materials. For this purpose, American ash (Fraxinus americana) and scotch pine (Pinus sylvest...

Aim of study: To produced end grain laminated parquets in different surface variations by using materials prepared by crosscut from branch woods of native wood species. Material and Methods: In the production of end grain laminated parquet, branch woods of yellow pine (Pinus sylvestris Lipsky), Eastern beech (Fagus orientalis Lipsky) and sessile oa...

Aim of study: To determine the scratch resistance of water-based varnishes modified with nanoparticles against accelerated UV aging effect in some ThermoWood materials. Material and Methods: American ash (Fraxinus americana) and scotch pine (Pinus sylvestris Lipsky) wood were heat treated at a temperature of 190 °C for 1,5 hours and 212 °C for 2 h...

The aim of this study is to determine the resistance properties of water-based varnishes modified with nanoparticles against accelerated UV aging effect in some ThermoWood materials.

This study aimed to investigate the characteristics of screw driving torques in wood-polymer composite (WPC) compatibilized with maleic anhydride-grafted polypropylene (MAPP). To meet this objective, pine wood flour, polypropylene with coupling agent (maleic anhydride grafted polypropylene) were compounded in a twin screw extruder. The process of s...

Heat treatment of wood materials is generally performed to improve the physical, mechanical, chemical, surface, thermal, and crystallinity characteristics. In this way, the usage areas of wood material in different purposes can be expanded by means of heat treatment. The goal of this study was to determine the physical, mechanical, chemical, crysta...

This paper examined the effect of machining parameters on surface roughness of medium density fiberboard (MDF) machined using a computer numerical control (CNC) router. The machining parameters such as spindle speed, feed rate, depth of cut, and tool diameter were examined for milling. The experiments were conducted at two levels of spindle speeds,...

The aim of this study is to determine changing of color and hardness values of heat treated wood exposed to hygrothermal aging. For this purpose, chestnut woods (Castanea sativa Mill.) have been used. Heat treatment applications were applied in a temperature controlled small heating unit. Experimental samples were subjected to heat under atmospheri...

This study has been held with the aim of determining technologic and mechanical properties of theterebinth (Pistaciaterebinthus L.). For this reason, moisture, density, hardness, shrinkage and swelling, bending strength, elastic modulus in bending, compressive strength and adhesion strength properties have been determined of theterebinth. Measureme...

Turkiye’nin deprem kusaginda yer alan bir ulke olarak sinirlari icerisinde bircok deprem meydana gelmistir. Yakin gelecekte de farkli bolgelerinde benzer siddetlerde depremlerin olabilecegi konunun uzmanlari tarafindan aciklanmaktadir. Kuzey Anadolu Fay Hatti uzerinde bulunan Kastamonu Ili Tosya Ilcesi I. Derece deprem bolgesinde yer aldigindan gec...

Physical, chemical, biological and microscopic properties change in unprotected wooden material exposed to weathering conditions. Decay in weathering is a result of chemical change in the cell walls that caused by the activities of microorganisms and primarily starting with the decomposition of lignin. Besides, wood surfaces are ruined by some effe...

Located on the way of silk road, Tosya is the biggest town of Kastamonu. When compared to the neighboring towns and among other towns in Kastamonu, Tosya has the most dynamic economy. Especially, furniture and carpenter industry-wood and forest products industry have an incredible effect and contribution on the economy of the town. Products, which...

The aim of this study was to restore the problems of pyhsical change of some wood materials exposed to weathering conditions using a bleaching process. For this purpose, wood samples of Scots pine (Pinus sylvestris L.), Eastern beech (Fagus orientalis L.), sessile oak (Quercus petraea L.), and chestnut (Castanea sativa Mill.) were exposed to weathe...

Tarihi ahşap yapı, donatı elemanları ve mobilyaların orijinal görünümüne tekrar kavuşturmak amacıyla uygulanan restorasyon çalışmaları, ahşap malzemenin gelecek nesillere korunarak aktarılmasında önemli bir yere sahiptir. Restorasyon çalışmalarında, ahşap malzeme üzerindeki toz, kir, yağ ve boya/vernik uygulamalarının temizlenmesi dikkat gerektiren...

This study has been held with the aim of determining changes in the hardness, gloss and color of Scotch Pine (PinussylvestrisL.), Eastern Beech (FagusorientalisL.), sessile oak (Quercuspetraea L.) and Anatolian Chestnut (Castanea sativa Mill.) woods which have been exposed to weathering conditions. For this reason, samples have been exposed to weat...

The aim of this study was to eliminate the problems of hardness, gloss, and color change of some wood materials exposed to weathering conditions using a bleaching procedure to attempt to return the wood material to its natural state. For this, wood samples of Scots pine (Pinus sylvestris L.), Eastern beech (Fagus orientalis L.), sessile oak (Quercu...

Physical, chemical, biological and microscopic properties change in unprotected wooden material that is exposed to weathering conditions and so its structural and some characteristic properties such as colour, gloss and hardness are ruined. The aim of this study is to determine changing of colour, gloss and hardness values of heat treated wood expo...
