Kodi mukukumbukira Melamine? Ndiwowonjezera "mkaka wa" mkaka ", koma chodabwitsa, mwina" kusandulika ".

Pa february 2, pepala lofufuzira linasindikizidwa m'chilengedwe, malo otsogola padziko lonse lapansi, omwe amanena kuti Melamine atha kupangidwa mwazinthu zolimba kuposa pulasitiki, zomwe anthu amadabwitsika. Pepala lidasindikizidwa ndi gulu lotsogozedwa ndi zida zasayansi zotchuka Michael Strano, pulofesa wotchuka wa Internoment of Missiner of the Massachuset Institute of Technology, ndipo Wolemba mnzake a Suwect a yuwect a yuwec.

Adanenanso zaZinthuYolembedwa kuchokera ku Melamine 2DPa-1, polymer awiri omwe amadzipangitsa kukhala ma sheet kuti apange bata kuti apange chuma chochepa kwambiri, champhamvu kwambiri, chomwe ma Patent alipo adasungidwa.

Melamine, yemwe nthawi zambiri amadziwika kuti Dimethylamine, ndi wonyezimira woyera yemwe amawoneka wofanana ndi mkaka p

Melamine siali wopanda madzi komanso sungunuka pang'ono m'madzi, komanso ku methanol, formaldehyde, glycect, pyridin, okonda ku Acetone ndi Ether. Zimakhala zovulaza thupi laumunthu, ndipo onse ku China ndipo omwe adafotokoza kuti Melamine sayenera kugwiritsidwa ntchito popanga zakudya kapena zowonjezera, makamaka mu zojambula zopangira, makamaka mu zojambula, zomata, zimagwiritsa ntchito zinthu zina zambiri.

Njira ya molecular ya Melamine ndi C3h6N6 ndi ma molecular kulemera ndi 126.12. Kudzera mu mtundu wake wa mankhwala, titha kudziwa kuti Melamine ili ndi zinthu zitatu, kaboni, haidrojeni ndi nayitrogeni, ndipo asayansi a mamolekyulo ndi ma molekyulu ake Mamolekyu amakhazikitsidwa limodzi, ndikupanga mawonekedwe a disc mokhazikika, monga mawonekedwe a hexagonal opangidwa ndi graphene ziwiri, ndipo mawonekedwe a Melamine amasinthidwa kukhala pepala lalikulu lotchedwa Polsomide m'manja mwa asayansi.

Zinthu zake sizovuta kupanga, strano inatero, ndipo imatha kupangidwa mwachangu mu yankho, pomwe filimuyo imatha kuchotsedwa pambuyo pake, zomwe zimapangitsa kuti pakhale njira yosavuta yopangira zinthu zopyapyala kwambiri.

Ofufuzawo adawona kuti zatsopanozi zili ndi modulus, zomwe zimafunikira kuti zisokoneze, ndizomwe zimafunikira kasanu ndi limodzi kuposa galasi lopirira. Anapezanso kuti ngakhale anali wachisanu ndi chimodzi monga chitsulo, monga chitsulo, polymer amakhala ndi mphamvu kawiri, kapena mphamvu yofunikira kuswa nkhaniyi.

Katundu wina wofunikira wa zinthuzo ndi undirend wake. Pomwe ma pointra ena amakhala ndi maunyolo opotoka omwe mpweya umatha kuthawa, zomwe zili zatsopano zomwe zimamatirana zomwe zimamatira limodzi monga mabodi a Lego ndi mamolekyulu sangathe pakati pawo.

Izi zimatithandiza kupanga zokutira zowonda zaumoyo zomwe zimagonjetsedwa ndi kulowa kwamadzi kapena gasi, "asayansi adatero. Mtundu wa zotchinga izi zitha kugwiritsidwa ntchito kuteteza zitsulo m'magalimoto ndi magalimoto achitsulo."

Tsopano ofufuzawo akuphunzira momwe polimani wina angapangire mapepala awiriwa mwatsatanetsatane ndipo akuyesera kusintha kapangidwe kake kake kuti apange mitundu ina ya zinthu zatsopano.

Zikuwonekeratu kuti izi ndi zofunika kwambiri, ndipo ngati zingakhale zopangidwa ndi zambiri, zitha kubweretsa kusintha kwakukulu kwa magalimoto, awespace, ndi minda yoteteza ku Chuma. Makamaka m'munda wamagetsi atsopano, ngakhale mayiko ambiri amalinganiza kuti athe kupemberera magalimoto a mafuta pambuyo pa 2035, koma mtundu wa mphamvu yatsopano yamagetsi ikadali vuto. Ngati zinthu zatsopanozi zitha kugwiritsidwa ntchito m'munda wamagalimoto, zikutanthauza kuti kulemera kwa magalimoto atsopano kudzachepetsedwa, komanso kuchepetsa kuchepa kwa mphamvu, komwe kumapangitsa kuti magalimoto azikhala ndi mphamvu zambiri.
