Naturalis lignum et metallum fuisse essentialis aedificium materiae ad homines in millia of annis.The synthetica Polymers nos vocant plastics sunt recens inventionem, quae exploded in 20th century.
Et metalla et plastics habent proprietatibus qui bene idonea ad industriae et commercial usommetals sunt fortis, rigida, et plerumque ad aere, aquae, et admodum sit amet, ut producere, cheap Commercial Plastics et terribilis structural materiae: plastic adjumenta sunt bona res, et nemo vult vivere in plastic house.additionally, sunt saepe excoliar a Fossil Fuels.
In quibusdam usibus naturalis lignum certet metallis et plastics.Most domus domos aedificatis lignum Framing.The problema est naturalis lignum et metallum maxime time.a in aquam ad reponere in Journal de ligneis et nils.how est in ligneis cultro et non uteris Quando cito?
Fibrosum structuram de lignis consistit circa L% Cellulose, naturalis polymer cum theoretically bonum robore properties.The reliqua dimidium lignea structure est maxime lignin et hemicellose est lignum in structure et ita confert, nihil ad silvam in structure structure et sic evacuat Cellulose fibris et praestat utile tasks ad vivum wood.But ad homines, ad compacting lignum et binding et cellulosis fibris magis arcte simul, Lignin est impedimentum.
In hoc studium naturalis lignum in indurabatur lignum (HW) in quattuor steps.firt, lignum coctum in sodium hydroxide et sodium sulfate ad removere aliquot hemicellulose et lignin.after reduces naturalem hastum et ligno cellulosa bonding Fibrings.Next, in lignum est pressurized ad CV ° C (CCXXI ° F) ad pauci plures horas ad perficiendam densificationem, et sic dried.finally, lignum est immersus in minerali oleum ad XLVIII horis ad perfecta uber wathoof.
Unum mechanica proprietas structural materia est incisum duritiam, quae est mensura eius facultatem ad resistere deformationis cum expressi per Force.Diamond est magis quam ferro, magis quam auro, ut Mohs Denarius est in Gemology, ut in Metricium Traditio est in Gemology, quod est in Metulas Ball.its in Gemology, quod est in Metrice est in Geminess In test superficiem cum quadam Force.measure diameter circularis incisum creatum a ball.The brinell duritia valorem est ratione usus mathematica formula; Doughly loqui, quod maius foraminis pila hits, molliori material.in hoc test, HW est XXIII temporibus durius quam naturalis lignum.
Increatos naturalis lignum absorbet aqua.This potest expand ligna et eventually perdere structural properties.The auctores usus duos-day mineralis inriguam ad augendam aquae resistentiam in Hydrophobic superficie aquae superficiei aquam droplets droplets Hydrophilic ("aqua amant") superficies, in altera manibus droplets plana (et deinde absorbet aquam facilius crescit hydrophobicity Hyder.
In some engineering tests, HW knives performed slightly better than metal knives.The authors claim that the HW knife is about three times as sharp as a commercially available knife.However, there is a caveat to this interesting result.Researchers are comparing table knives, or what we might call butter knives.These are not meant to be particularly sharp.The authors show a video of their knife cutting a steak, but a reasonably strong adult could probably cut Eodem CARNIS cum hebes parte metallum furca et CARNIS cultro ut opus multo magis.
Quid de clavis? Unum HW clavus apparenter facile dirum in ACERVUS trium consiliis, quamvis non ut detailed relative ad ferrum Nails.wooden paxillosque seorsum, cum adampere utrique casibus non exposita, ut et in utroque casibus defuit ante vel clavum, ut utroque casibus defuit ante vel clavum, ut et in utroque casibus non exposita, ut et in utroque casibus defuit antequam vel clavum, ut utraque defecerunt antea vel clavus et in utroque casibus non exposita, ut et in utroque casibus non exposita, ita utrique in utroque nails non exposita, ita utrique in utroque nails non exposita, ita utrique in utroque nails non patere.
Sunt hw clavos melius in aliis via? Ligne paxillos levior, sed pondus structura non praesertim pulsus massa paxillos qui teneat Together.wooden paxillos non Rust.However non impervium aquae aut biodecompose.
There is no doubt that the author has developed a process to make wood stronger than natural wood.However, the utility of hardware for any particular job requires further study.Can it be as cheap and resource-less as plastic?Can it compete with stronger, more attractive, infinitely reusable metal objects?Their research raises interesting questions.Ongoing engineering (and ultimately the market) will answer them.
