Ungacinga? “Izinto zasesibhakabhakeni” ezazisetyenziswa kwiibhokisi zeerokhethi kunye neebhleyidi zeturbine yomoya ngoku ziphinda zibhale imbali yokuqinisa izakhiwo – ziyinyani.umnatha wefayibha yekhabhoni.

• I-Aerospace genetics ngeminyaka yoo-1960:

Imveliso yemizi-mveliso yee-filaments ze-carbon fiber ivumele le nto, enamandla ngokuphindwe kasithoba kunentsimbi kodwa ilula ngekota ezintathu, ukuba ingeniswe ebantwini okokuqala. Ekuqaleni yayigcinelwe "amacandelo aphambili" afana neenqwelo-moya kunye nezixhobo zemidlalo eziphezulu, yayilukiwe kusetyenziswa iindlela zelaphu zemveli, kodwa yayinamandla okuguqula ihlabathi libe libi.

• Inguqu enkulu kwi "mfazwe nxamnye nentsimbi":

I-mesh yokuqinisa eqhelekileyo ifana "ne-codger endala" yehlabathi lokwakha: inobunzima obufana nobendlovu (malunga ne-25 kg nge-square meter ye-mesh yokuqinisa), kwaye ikwayoyika ityuwa, amanzi, kunye nexesha - - Ukukhukuliseka kwe-ion ye-chloride kubangela ukuba ukuqina kwentsimbi kwande kwaye kuqhekeke.
Ukuvela kweilaphu le-mesh yefayibha yekhabhoniiphula ngokupheleleyo i-deadlock: ngokusebenzisa i-directional weaving + impregnation ye-epoxy resin, yenza ubukhulu bomaleko wokuqinisa ukusuka kwi-5cm ukuya kwi-1.5cm, ubunzima buyi-1/4 kuphela ye-rebar, kodwa ikwamelana ne-asidi kunye ne-alkali, amanzi olwandle, kwaye ekuqiniseni ibhulorho elwandle, akukho phawu lokugqwala kangangeminyaka engama-20.

Kutheni iinjineli zingxama ukuyisebenzisa? Kutyhilwe iingenelo ezintlanu ezinzima

ugxininiso:ulwakhiwo kufuneka lusetyenziswe ukufanisa i-polymer mortar! Indawo ethile isebenzise i-mortar eqhelekileyo ngempazamo, nto leyo ebangele ukuba amadrum aqiniswe aze awe — njengokuba i-glue inamathela kwiglasi, i-glue ayilunganga njengokuchithwa komsebenzi.

Ukusuka kwiSixeko Esingavumelekanga Ukuya kwiBhulorho eNqamlezileyo yoLwandle: Itshintsha Ihlabathi Ngokuzolileyo

• "Ibhandishi Engabonakaliyo" yeLifa leNkcubeko kunye neZakhiwo zamandulo:

I-Beyer Bau, isakhiwo esineminyaka elikhulu ubudala eTechnische Universität Dresden eJamani, yayifuna ukuphuculwa ngokukhawuleza ngenxa yokwanda kwemithwalo, kodwa yayiphantsi kwemiqathango ebekwe lukhuseleko lwesikhumbuzo. Iinjineli ezinelaphu le-carbon fiber mesh eliyi-6mm ubukhulu + umaleko obhityileyo wesamente, ezantsi komqadi "zincamathisela" umaleko "webhendi ecacileyo", kungekuphela nje ukuze amandla okuthwala umthwalo anyuse i-50%, kodwa kwakhona ayitshintshanga isakhiwo kwimbonakalo yaso yokuqala, kwaye neengcali zeBhodi yeLifa ziye zancoma: ". Njengokwenza isakhiwo esidala ukwenza i-facelift engenamabala".

• Ubunjineli bezithuthi "i-super patch":

IFlorida, eMelika, iintsika zebhulorho ezinqumla ulwandle, eziqiniswe ngelaphu le-carbon fiber mesh ngo-2003, amandla avela "kwababuthathaka" anyuke ngama-420%, kwaye ngoku emva kweminyaka engama-20, iinkanyamba zisazinzile njengentaba elunxwemeni. Iprojekthi yasekhaya ye-Hong Kong-Zhuhai-Macao Bridge island tunnel, nayo yayisebenzisa ngokuthula ukwenza uphuculo lwesakhiwo, ngokuchasene nokukhukuliseka kwamanzi olwandle.

• "Isixhobo somlingo esiguqula ubudala" sesilwanyana esincinci esidala nesigugileyo:

Kwindawo yasekuhlaleni yama-80 eBeijing, ii-floor slabs zaziqhekeke kakhulu, kwaye icebo lokuqala yayikukudiliza nokwakha ngokutsha. Kamva nge-carbon fiber mesh cloth kunye ne-polymer mortar reinforcement, ixabiso nge-square meter liyi-200 yuan kuphela, kunokwakhiwa kwakhona kwe-80% yeendleko zokonga, kwaye ngoku abahlali bathi: “ziva ngathi indlu incinci ngeminyaka engama-30!”
Ikamva lifikile: Ukuziphilisa, ukujonga "izinto ezikrelekrele" kusendleleni

• "Ugqirha oziphilisayo" obhalwe ngokoqobo:

Izazinzulu zenza i-mesh yekhabhoni “ephilisayo” — xa kuvela imifantu kwisakhiwo, i-mesh ingasetyenziswa njengento yokuqinisa. — Xa kuvela imifantu kwisakhiwo, ii-capsules kwisixhobo ziyaqhekeka ukuze zikhuphe izinto zokulungisa ezizalisa ngokuzenzekelayo imifantu. Uvavanyo olwenziwe kwilebhu e-UK lubonise ukuba esi sixhobo sinokwandisa ubomi bekhonkrithi ukuya kuthi ga kwiminyaka engama-200.

• "Isongo sempilo" sezakhiwo:

ifaka ii-sensors ze-fiber-optic kwiumnatha wefayibha yekhabhoni, njenge "wotshi ekrelekrele" yezakhiwo: isakhiwo esibalulekileyo eShanghai siyisebenzisa ukujonga ukuhlaliswa kunye nokuqhekeka ngexesha langempela, kwaye idatha idluliselwa ngqo kwi-ofisi yangasemva yolawulo, esebenza ngokuphindwe kalikhulu kunokuhlolwa kwesandla kwendabuko. Isebenza ngokuphindwe kalikhulu kunokuhlolwa kwesandla kwendabuko.
Iingcebiso eziluncedo kwiinjineli nakubanini bazo
1. Izinto ezisetyenziswayo zikhetha eyona ifanelekileyo, iziphumo ziphindwe kabini kunesiqingatha somzamo:Qaphela iimveliso ezinamandla okutsalwa ≥ 3400MPa kunye ne-modulus of elasticity ≥ 230GPa, kwaye ungacela abavelisi ukuba banike iingxelo zovavanyo.
2. Musani ukuba ngamavila ekwakheni:Umphezulu wesiseko kufuneka ucocwe kakuhle, kwaye udongwe lwepolymer luxutywe ngokwemilinganiselo.
3. Ukulungiswa kwesakhiwo esidala kuphambili:Xa kuthelekiswa nokudilizwa nokwakhiwa kwakhona, ukuqinisa i-carbon fiber mesh kunokugcina imbonakalo yokuqala yesakhiwo, kodwa kukwagcina ngaphezulu kwama-60% eendleko.
Isiphelo
Xa izinto zeenqwelo-moya "zisiya emhlabeni" kwintsimi yokwakha, ngequbuliso safumanisa: ukuqinisa kokuqala akunakudinga ukwenza imizamo emikhulu, isakhiwo sakudala sokuqala sinokuba "kukukhula okungasemva".Ilaphu le-mesh yefayibha yekhabhoniifana “neqhawe elikhulu” kushishino lokwakha, eneempawu ezikhanyayo, ezomeleleyo nezihlala ixesha elide, kangangokuba isakhiwo ngasinye esidala sinethuba lokuhlaziya ubomi baso – kwaye oku kusenokuba sisiqalo nje soguquko lwezinto eziphathekayo.
