Elektrostatik toz boyalar otomotiv ve beyaz eşya gibi iletken metalik yüzeyler üzerine uygulanmaktadır. uçucu organik bileşik içermemesi, çevre, iş güvenliği işçi sağlığı açısından diğer sıvı boyalara göre daha avantajlıdır. Bu avantajlarından dolayı son zamanlarda olmayan plastik, ahşap esaslı levhalara uygulanması yönünde birçok araştırma geliştirme faaliyetleri yürütülmektedir. çalışmada lev...

ing technology, around 30 years ago, was an important milestone for the coatings sector offering an environmentally benign application process that could deliver an excellent finish. Today, the use of powder coatings is widespread, particularly in the durable goods market, with the automotive industry providing excellent prospects for longer-term growth. The more recent development of powders w...

Wood finishes protect the surface of wood from external agents, enhance its looks and improve its gloss (luster). On constant external exposure, UV rays gradually degrade the film coating resulting in loss of gloss. In this study, two commonly used finishes namely spirit shellac and polyurethane finish were used to investigate the pattern of loss of gloss due to UV interference. Two coatings of...

A versatile, fast, and nature-inspired polyphenol chemistry surface modification was applied to prepare superhydrophobic surfaces with micro-grooved structures in this study. Tannic acid and iron ion (TA–FeIII) complexes were employed as a molecular building block for anchoring biomimetic coating onto the wood substrate with catalytically reducing formative Ag ions as the rough surface to ensur...

The paper describes a novel method of drilling into hard non-conductive materials by localized microwave energy (US patent 6,114,676). The Microwave Drill implementation may utilize a conventional 2.45GHz magnetron, to form a portable and relatively simple drilling tool. The drilling head consists of a coaxial guide and a near-field concentrator. The latter focuses the microwave radiation into ...

In this study some of the important properties of experimentally manufactured wood– plastic composites (WPC) were determined. Specimen having 60% and 80% particle and fibre of radiata pine (Pinus radiata ) were mixed with polypropylene (plastic) and four different additives, namely Struktol TR 016 which is coupling agent, CIBA antimicrobial agent (IRGAGUARD F3510) as fungicide, CIBA UV filter c...

A hot, dry wind envelopes a statuesque woman as she kneels over wind-sifted trays of tinbearing pulverized ore in Uis, Namibia. In Bolivia, a nine-year old girl scrambles down a steep pit wall yet again to refill her bucket of metal-rich sand. And yet another woman stokes the fire in her wood burning stove in the Philippines, releasing the mercury from doré in a poorly ventilated kitchen; the t...

Application of terahertz (THz) electromagnetic waves offers several opportunities for quality inspection in various industries. The THz waves penetrate many kinds of materials such as pharmaceutical coating, paper, plastic, ceramic, cardboard, wood, clothing, etc. We investigated possibilities of applying a THz imaging system in transmission geometry using the organic DSTMS crystals as a THz ge...

The study investigated the effects of short-term thermo-mechanical (STTM) densification temperature and pressure on changes in surface wettability of alder (Alnus glutinosa), beech (Fagus sylvatica), birch (Betula verrucosa) and pine (Pinus sylvestris) wood veneer. Veneer sheets were densified using pressure levels of 4 MPa, 8 MPa and 12 MPa at three temperatures: 100°C, 150°C and 200°C for a s...

the major objectives of this study were to find out the mechanism behind the sapstaining fungal hyphae penetration into wood elements using electron microscope and to evaluate the exact role of phenolic compounds existing in wood vinegar towards the sapstaining fungal growth inhibition. to formulate the new environmental friendly wood preservative, we neutralized (to ph 7) wood vinegar with nao...
