Guns to guns usually used toxic petroleum-based adhesives
SHUTTERTOCK / EKATERINA43
A product of the wood industry has become a safe and available hot-gun glue that can replace solvent-based adhesives to poison people and around.
ZIWEN LV In the Beijing Forestry University in China and colleagues make glue from an Xylan, a substance of the plant’s walls of the plant.
“Xylan is the material holding the cellulose together, even if it is not itself a ‘glue’ in the traditional sense,” as Nick Aldred At the University of Essex, UK, not included in the study. “This work is trying to implement it as a glue.”
The LV team uses sodium sodium and sodium boroydride to Chemical Chemical again in Xylan, making it in Dialia in the Xylan dialan.
They say the resulting glue, released from a hot gun, there is a strong bond of 30 megapascals, which is superior to the usual adhentives, including epoxy resin. The glue can also be again through the melting it, and maintain its original strength in adhesion even after 10 cycles.
The team also built Plywood, with three sheets of thin wooden walnut combined with Xylan plighled with phenol-foramdehydehyde difesives.
But Xylan Plywood has an important disadvantage. After the water washing for an hour, the glue melts, causing layers to separate. Researchers do not respond to New ScientistComment requests for comment.
Jonathan Wilker In Purdue University, Indiana, says lasting alternatives needed for all petrol-based adhesives used today.
“(The) Bonding performance (in the new glue) looks to be large, especially with wood substrates,” Wilker said. “Evaluation of life cycle and resistance to resisting water results with no significant incumbent glues are currently used.”
“If it could be rolled into the size of the plywood industry, it could be a change,” aldred said. “Plywood is one of the last residual consumer products with materials such as phenol and formaldehyde, which are prohibited by products such as cosmetics years ago.”
