Kodi mungaganizire? "Chida chamlengalenga" chomwe kale chinkagwiritsidwa ntchito m'mabokosi a roketi ndi masamba a turbine ya mphepo tsopano chikulembanso mbiri ya zomangira zolimbitsa - ndiulusi wa kaboni.

• Ma genetic a mumlengalenga m'zaka za m'ma 1960:

Kupanga kwa ulusi wa kaboni m'mafakitale kunalola kuti zinthuzi, zomwe ndi zolimba kuwirikiza kasanu ndi kanayi kuposa chitsulo koma zopepuka kwambiri kuposa magawo atatu mwa anayi, zidziwike kwa anthu koyamba. Poyamba zinkagwiritsidwa ntchito pa "magawo apamwamba" monga ndege ndi zida zapamwamba zamasewera, zinkalukidwa pogwiritsa ntchito njira zachikhalidwe za nsalu, koma zinali ndi kuthekera kosintha dziko lapansi.

• Kusintha kwa "nkhondo yolimbana ndi chitsulo":

Unyolo wolimbitsa wachizolowezi uli ngati "codger wakale" wa dziko lomanga: umalemera ngati njovu (pafupifupi 25 kg pa mita imodzi ya sikweya ya unyolo wolimbitsa), ndipo umawopanso mchere, madzi, ndi nthawi - - Kuwonongeka kwa ayoni ya chloride kumapangitsa kuti chitsulo chizikula ndikusweka.
Kutuluka kwansalu ya ulusi wa kaboniZimaphwanya kwathunthu kusagwirizana: kudzera mu kuluka kolunjika + kuyikapo epoxy resin, zimapangitsa makulidwe a gawo lolimbitsa kuchokera pa 5cm mpaka 1.5cm, kulemera kwake ndi 1/4 yokha ya rebar, komanso kukana asidi ndi alkali, madzi a m'nyanja, ndipo pakulimbitsa mlatho panyanja, palibe chizindikiro cha dzimbiri kwa zaka 20.

N’chifukwa chiyani mainjiniya akufulumira kugwiritsa ntchito? Ubwino asanu wovuta wavumbulutsidwa

kutsindika:Kapangidwe kake kayenera kugwiritsidwa ntchito kuti kagwirizane ndi matope a polima! Anthu ammudzi agwiritsa ntchito matope wamba molakwika, zomwe zimapangitsa kuti ng'oma ziume ndikugwa — monga momwe zimakhalira ndi guluu pomamatira galasi, guluu siwoyenera kungokhala ngati kuwononga ntchito.

Kuchokera ku Mzinda Woletsedwa Kupita ku Mlatho Wodutsa Nyanja: Kukusintha Dziko Mosabisa

• "Bandeji Yosaoneka" ya Cholowa Chachikhalidwe ndi Nyumba Zakale:

Nyumba ya Beyer Bau, yomwe ili ndi zaka zana ku Technische Universität Dresden ku Germany, inkafunika kukonzedwanso mwachangu chifukwa cha kuchuluka kwa katundu, koma inali pansi pa zoletsa zomwe zinaperekedwa ndi chitetezo cha zipilala. Mainjiniya okhala ndi nsalu yopyapyala ya carbon fiber yokwana 6mm + wosanjikiza woonda wa matope, pansi pa mtengowo "pakani" wosanjikiza wa "transparent band-aid", osati kuti mphamvu yonyamula katundu iwonjezere 50%, komanso sinasinthe nyumbayo pang'ono poyambirira, ndipo ngakhale akatswiri a Heritage Board adayamikira: ". Monga momwe nyumba yakale imachitira kukweza nkhope popanda zipsera".

• "Super Patch" ya uinjiniya wamagalimoto:

Florida, United States, mizati ya mlatho wodutsa nyanja, yolimbikitsidwa ndi nsalu ya ulusi wa kaboni mu 2003, mphamvu kuchokera ku "zofooka" idakwera ndi 420%, ndipo tsopano patatha zaka 20, mphepo zamkuntho zikadali zokhazikika ngati phiri lomwe lili m'mphepete mwa nyanja. Ntchito yapakhomo ya Hong Kong-Zhuhai-Macao Bridge island tunnel, idagwiritsanso ntchito mwakachetechete kukonza kapangidwe kake, motsutsana ndi kukokoloka kwa madzi a m'nyanja.

• "Chida chamatsenga chobwezeretsa ukalamba" cha kakang'ono kakale komanso kowonongeka:

M'dera la m'ma 80 ku Beijing, miyala ya pansi inasweka kwambiri, ndipo cholinga choyambirira chinali kugwetsa ndi kumanganso. Pambuyo pake ndi nsalu ya carbon fiber mesh + polymer mortar reinforcement, mtengo pa mita imodzi ndi 200 yuan yokha, kuposa kumanganso kwa 80% ya ndalama zosungira, ndipo tsopano okhalamo akuti: "Imvani nyumbayo ili ndi zaka 30!"
Tsogolo lafika: Kudzichiritsa, kuyang'anira "zipangizo zanzeru" kukubwera

• "Dokotala wodzichiritsa yekha" wopangidwa ndi konkire:

Asayansi akupanga ulusi wa kaboni womwe "umadzichiritsa wokha" - pamene ming'alu ing'onoing'ono imachitika m'nyumba, ulusiwo ungagwiritsidwe ntchito ngati cholimbitsa. - Pamene ming'alu ing'onoing'ono ikuwonekera m'nyumba, makapisozi mu chinthucho amaphulika kuti atulutse zinthu zokonzanso zomwe zimadzaza ming'aluyo zokha. Mayeso ku labu ku UK asonyeza kuti chinthucho chikhoza kukulitsa moyo wa konkire ndi zaka 200.

• "Chibangili cha thanzi" cha nyumba:

imayika masensa a fiber-optic muulusi wa kaboni, monga "wotchi yanzeru" ya nyumba: nyumba yodziwika bwino ku Shanghai imagwiritsa ntchito kuyang'anira kukhazikika ndi ming'alu nthawi yeniyeni, ndipo deta imatumizidwa mwachindunji ku ofesi yoyang'anira, yomwe ndi yothandiza kwambiri nthawi 100 kuposa kuyang'anira kwachikhalidwe kwamanja. Ndi yothandiza kwambiri nthawi 100 kuposa kuyang'anira kwachikhalidwe kwamanja.
Malangizo abwino kwa mainjiniya ndi eni ake
1. Zipangizo zimasankha yoyenera, kawiri zotsatira zake ndi theka la khama:Dziwani zinthu zomwe zili ndi mphamvu yokoka ≥ 3400MPa ndi modulus of elasticity ≥ 230GPa, ndipo mutha kupempha opanga kuti akupatseni malipoti oyesera.
2. Musakhale aulesi pa ntchito yomanga:Pansi pake payenera kupukutidwa bwino, ndipo matope a polima asakanizidwe malinga ndi kuchuluka kwake.
3. Chofunika kwambiri pakukonzanso nyumba yakale:Poyerekeza ndi kugwetsa ndi kumanganso, kulimbitsa maukonde a ulusi wa kaboni kumatha kusunga mawonekedwe oyambirira a nyumbayo, komanso kusunga ndalama zoposa 60%.
Mapeto
Pamene zipangizo zamlengalenga "zinafika pansi" kumunda womanga, mwadzidzidzi tinapeza: kulimbitsa koyambirira sikungafunike kuchita khama lalikulu, nyumba yakale yoyambirira ikhozanso kukhala "kukula kobwerera m'mbuyo".Nsalu ya ulusi wa kaboniili ngati "ngwazi yayikulu" mumakampani omanga, yokhala ndi mawonekedwe opepuka, olimba komanso olimba, kotero kuti nyumba iliyonse yakale ili ndi mwayi wokonzanso moyo wake - ndipo izi zitha kukhala chiyambi chabe cha kusintha kwa zinthu zakuthupi.
