“…Addition of ADP until 10 wt% in the manufacturing of binderless board improved the board properties and changed water-soluble components of oil palm trunk to water-insoluble components (Komariah et al 2019). Application of sucrose-ammonium dihydrogen phosphate adhesives with a high solids content and suitable viscosities in plywood manufacturing operations was developed by Zhao et al (2019b), Sun et al (2019b), andZhao et al (2020).…”

Bamboo is a potential non-wood lignocellulosic material from which to make particleboard. Sucrose-based adhesive is another potential ingredient, but its use in particleboard has been limited. Addition of ammonium dihydrogen phosphate (ADP) can be used to increase the bonding ability of sucrose-based adhesive and to reduce the required pressing temperature. Therefore, this research used different pressing temperatures and sucrose/ammonium dihydrogen phosphate (ADP) composition ratios to optimize the properties of particleboards. The physical and mechanical properties of the boards were analyzed and compared with the JIS A 5908 (2003) standard for particleboard. The results showed that the interaction of the sucrose-ADP composition ratio and the pressing temperature significantly affected the physical and mechanical properties of the particleboards. The particleboard using only sucrose as adhesive had optimum properties at 200 °C; however, after addition of ADP, the intended properties could be achieved at a 160 °C pressing temperature.

“…The microstructure of the Polymers 2020, 12, 552 4 of 12 finish film was tested by Quanta 200 environment scanning electron microscope (SEM), FEI Company (Hillsboro, OR, USA). The chemical composition of the finish film was tested by a VERTEX 80v infrared spectrometer, Germany BRUKER Co., Ltd., Karlsruhe, Germany [17]. The ageing and stability test was measured in a ZN ultraviolet weather resistance tester (Nanjing Environmental Test Equipment Co., Ltd., Nanjing, China).…”

Effect of Concentration of Thermochromic Ink on Performance of Waterborne Finish Films for the Surface of Cunninghamia Lanceolata

Using Cunninghamia lanceolata as a substrate, the thermochromic ink was added to the waterborne finish to test the optical properties and mechanical properties of the finish film. The results showed that the discoloration performance of the finish film with 15.0% and 30.0% of the thermochromic ink was better. The gloss of the finish film changes irregularly when the concentration increases. The finish film with a thermochromic ink concentration of 10.0% has the highest gloss, and with a concentration of 30.0% has the lowest gloss. When the thermochromic ink concentration exceeds 15.0%, the impact resistance of the finish film is slightly enhanced. The concentration is not related to the liquid resistance of the finish film. When the thermochromic ink concentration was 0–15.0%, the particle distribution uniform reunion was not much. The discoloration mechanism of discolored finish film can be considered to be as follows. After adding thermochromic ink, when the finish film temperature rises, it fades from red to colorless. When the temperature is lowered, the thermochromic ink changes to its original colour again, and the thermochromic effect is stable and sustainable. On the basis of the above results, when the thermochromic ink concentration is 15.0%, the general performance of the waterborne finish film on the Cunninghamia lanceolata surface is the best. This study provides new prospects in using thermochromic ink for waterborne finish film.

“…Based on previously findings, it is well known that both nano-TiO 2 and nano-ZnO provide thermal stability, and to date several attempts have been made to endow wood with flame retardancy by using nano-TiO 2 or nano-ZnO as an effective inorganic barrier [19][20][21][22]. Additionally, natural polyelectrolytes such as chitosan, pectin, alginate, and xanthan gum have great potential for use in this area [23].…”

Composite coatings of inorganic nanomaterials with polyelectrolytes are promising materials for wood modification. Endowing wood with flame retardancy behavior can not only broaden the range of applications of wood, but also improve the safety of wood products. In this work, chitosan/sodium phytate/TiO2-ZnO nanoparticle (CH/SP/nano-TiO2-ZnO) composite coatings were coated on wood surface through layer-by-layer self-assembly. The morphology and chemical composition of the modified wood samples were analyzed using scanning electron microscopy and energy dispersive spectrometry. The thermal degradation properties and flame retardancy of the samples treated with different assembly structures were observed by thermogravimetric analysis, limiting oxygen test, and combustion test. Due to the presence of an effective intumescent flame retardant system and a physical barrier, the CH/SP/nano-TiO2-ZnO coatings exhibited the best flame retardant performance and required only approximately six seconds for self-extinguishing. The coated samples had a limiting oxygen index of 8.4% greater than the original wood.
