Formaldehyde is a volatile organic compound that is widely used in textiles, paper, wood composites, and household materials. Formaldehyde will continuously outgas from manufactured wood products such as furniture, with adverse health effects resulting from prolonged low-level exposure. New, microfabricated sensors for formaldehyde have been developed to meet the need for portable, low-power ga...

The interest in the development of biobased adhesives has increased due to environmental concerns. Moreover, as production engineered wood products (EWPs) is expected grow, market needs transit toward formaldehyde-free products. Cellulose nanoparticles (CNPs) are a material with unique properties and advantages for producing hybrid materials adhesives. Besides their traditional use reinforcing ...

Organosolv wheat straw lignin extracted using the CIMV process is a linear, low molecular weight, and natural phenolic oligomer. In this study, organosolv wheat straw lignin was tested as a substitute for 50% to 70% of the phenol in a phenol-formaldehyde-resol resin. The lignin was used without any chemical modification in a one-step synthesis reaction. Parameters such as reaction time and form...

in this study, the possibility of using canola stem residues for particleboard manufacturing was studied. the ratio of canola straw to the industrial particles was as 25:50, 50:50, 75:25 and 100:00 percents, respectively. urea formaldehyde resin was used as binder at three levels of 8, 10 and 12 percent based on oven dried weight of particles and the press time was at three level of 5, 6 and 7 ...

By focusing on the disadvantages of weak water resistance and high formaldehyde emission urea–formaldehyde resin (UF), this research provides a new method to overcome these shortages UF by using tannin for partial substitution urea. Furthermore, plasma pretreatment wood was introduced strengthen bonding performance plywood. The investigation chemical structure tannin–urea–formaldehyde (TUF) wer...
