Mtengo wa fakitale China nylon pom hdpe pp pepala

Asayansi apanga pulasitiki yofanana ndi zitsulo - zolimba koma zosalemera.Plastics, omwe nthawi zina amatchulapo ma poizoni obwereza. amabwera mu mawonekedwe a membrane.ilinso nthawi 50 zochulukirapo kuposa pulasitiki kwambiri Kaphatikizidwe. Njira, zomwe zimachitika kutentha kwa firiji, kumafunikira zida zotsika mtengo, ndipo polymer imatha kukhala yopangidwa m'matumbo akuluakulu omwe ali ndi ma nanometer okhawo omwe apeza Fen. 2 mu magazini.
Nkhani yomwe ikufunsidwa imatchedwa Polymide Chovala chogonjetsedwa: Zomangira za hydrogen m'mphepete mwa maunyolo athunthu, zomwe zimawonjezera mphamvu yonse.
"Amamamatira monga velcro," adati Wotsogolera Mit Michael, mankhwala osokoneza bongo amangofuna kungophwanya unyolo payekha, komanso kuthana ndi zingwe zazitali zamitundu imkati zomwe zimalowetsa mtolo wa polymer.
Kuphatikiza apo, ma polima atsopano amatha kupanga mawonekedwe owoneka bwino. Lumikizanani mumitundu itatu, mosasamala kanthu za kutsata.But Strenors's ma poizoni akukula mwanjira yapadera mu 2d kupanga nanosites.
"Kodi mutha kusokoneza pepala? Zimakhala kunja, simungathe kuchita mpaka ntchito yathu. "Chifukwa chake, tinapeza chinthu chatsopano." M'ntchito yaposachedwa iyi, gulu lake lidagonjetsa vuto kuti apange maphatikizidwe azomwe ali ndi vutoli.
Chifukwa chomwe Poloparamides ali ndi kapangidwe kake ndikuti polymer synthesis amakhudzana ndi masitepe otchedwa AutoCatalyc: popeza polymer imachulukitsa moments opanga njira yoyenera kuti mulimbikitse mgwirizano wa Awiri.duningsal mawonekedwe. Omwe amayamba kupanga inchi-yayikulu kwambiri imakhala yochepera 4 nanometers wandiweyani.
Kuti mukwaniritse makina opanga ma polima, ofufuzawo adayesa mphamvu yomwe ikufunika kuti isuke ndi mabotolo abwino a Nylon, nsalu zomwe zimagwiritsidwa ntchito popanga parachulute. Zimatenga mphamvu yochulukirapo yokhomera kwambiri polyamide yapamwamba iyi ngati chitsulo chofananira komanso kubuluka ku Strano, Zinthu zitha kugwiritsidwa ntchito ngati chomangira pamalo achitsulo, monga mikwingwirima yagalimoto, kapena ngati fyuluta yoyeza, iyenera kukhala yocheperako koma yamphamvu yokwanira kuthana ndi zovuta zambiri, Zoyipitsa mu zomaliza zomaliza - zokwanira pazinthu za polyamide.
M'tsogolomu, strano ikuyembekeza kukulitsa njira zowonjezera polymerization kupita ku ma polima osiyanasiyana kuposa analogi iyi. "Akutero oyiwazungulira." Ingoganizirani kutembenuza mitundu yambiri ya ma polima, ngakhale zochitika zopondera zomwe zimatha kupanga magetsi kapena mafilimu oonda omwe amatha kuphimba mitundu yamitundu ino, mwina mitundu ina ya anthu omwe angathe kugwiritsidwa ntchito tsopano, " Stano adati.
M'dziko lozunguliridwa ndi pulasitiki, lomwe lili ndi chifukwa chosangalalira ndi polymer yomwe mphamvu inayake ndi yolimba, yolimba imakhala yolimba kwambiri, Ndi zida zochepa komanso zolimba.strano yowonjezera pamtunda wokhazikika, wopatsa mphamvu kwambiri wa 2D ndi gawo lolowera kumanja kuti asule dziko kuchokera pulasitiki.
Shi en kim (monga momwe amatchedwa Kim) ndi wolemba Sayansi ya Chimesian-Wofalitsira Ma Spridiory 2022 adalemba zochulukirapo m'malo akunja.
Stoeing Spacecraft yayambanso kufikira malo apadziko lonse lapansi, koma akatswiri ali ndi chiyembekezo chokhudza kuthawa kwachitatu.
Ndife ochita nawo ku Amazon Services Programs, pulogalamu yotsatsa yotsatsira yomwe imapangidwa kuti ipereke njira yolumikizirana ndi maazon.com ndi ogwirizanitsa kapena kugwiritsa ntchito tsambali kuvomera kuvomerezedwa kwathu.
