Ngaba unokuthelekelela? “Isixhobo esisemajukujukwini” esasifudula sisetyenziswa kwimijukujelwa yeerokethi kunye neebhleyidi zeinjini yomoya ngoku sibhala kwakhona imbali yokuqinisa isakhiwo –carbon fiber mesh.
- I-aerospace genetics ngeminyaka yoo-1960:
Imveliso yemizi-mveliso ye-carbon fiber filaments ivumele le nto, eyomeleleyo ngokuphindwe alithoba kunentsimbi kodwa i-quarter-quarter lighter, ukuba ifakwe kuluntu okokuqala. Ekuqaleni ibigcinelwe “amacandelo aphakamileyo” anje nge-aerospace kunye nezixhobo zemidlalo ezikumgangatho ophezulu, yayilukiwe kusetyenziswa iindlela ezilukiweyo zemveli, kodwa yayinamandla okuguqula umhlaba.
- Inguquko kwi "war on steel":
Umnatha wokuqinisa oqhelekileyo ufana “ne-codger endala” yelizwe lolwakhiwo: inobunzima obungangendlovu (malunga ne-25 kg nge-square meter ye-reinforcement mesh), kwaye yoyika ityuwa, amanzi, kunye nexesha – - Ukhukuliseko lwe-ion ye-chloride ibangela ukuba ukuqina kwentsimbi kwande nokuqhekeka.
Ukuvela kweilaphu le-carbon fiber meshyaphula ngokupheleleyo i-deadlock: ngokulukwa kwe-directional + epoxy resin imregnation, yenza ubukhulu bomgangatho wokuqinisa ukusuka kwi-5cm ukuya kwi-1.5cm, ubunzima buyi-1/4 kuphela ye-rebar, kodwa iyakwazi ukumelana ne-asidi kunye ne-alkali, amanzi olwandle, kunye nokomelezwa kwebhulorho elwandle, akukho phawu lwe-20 ye-corrosion.
Kutheni iinjineli zingxamele ukuzisebenzisa? Iinzuzo ezintlanu ezinzima zityhiliwe
| Iingenelo | Ukomelezwa kwentsimbi yesiNtu / ilaphu le-carbon fiber vs ilaphu le-carbon fiber mesh | Isifaniso sobomi |
| Ukukhanya njengentsiba, yomelele njengentsimbi | I-15mm engqindilili yokuqinisa umaleko inokumelana ne-3400MPa amandla okuqina (ilingana nentonga enye yokubamba iindlovu ezi-3), i-75% ikhaphukhaphu kune-rebar | Ngokufana nesakhiwo ukunxiba "ihempe yangaphantsi ye-bullet-proof", kodwa ayinyusi ubunzima |
| Ukwakhiwa njengokupeyinta udonga Ngokulula njengoko | Akukho ukuwelda, ukubopha, udaka lwepolymer ngokuthe ngqo, iprojekthi yokuqinisa isikolo eBeijing kunye nayo ukunciphisa ixesha lokwakha ngama-40%. | Yonga ngaphezu kweethayile, abantu abaqhelekileyo banokufunda |
| Ukumelana nomlilo ukwakha ngokugqithisileyo | I-400 ℃ amandla obushushu obuphezulu ahlala engatshintshi, ivenkile yokuthenga iqiniswa ngokwamkelwa komlilo, ngelixa i-adhesive ye-epoxy resin yendabuko iya kuthanjiswa kwi-200 ℃ | Ilingana nokunxiba "isuti yomlilo" kwisakhiwo " |
| Ikhulu leminyaka hayi kakubi 'isilondolozi' | Ifayibha yeCarbon yinto engasebenziyo, esetyenziswa kwisityalo sekhemikhali kwindawo eneasidi eyomeleleyo iminyaka eyi-15 ngaphandle komonakalo, ngelixa i-rebar kudala irula ibe yi-slag. | kunentsimbi engatyiwayo ikwaxhathisa ukwenza "isitofu sokugonya" |
| Iindlela ezimbini zokulwa nenyikima "inkosi yekarati" | Ulwalathiso lwexesha elide kunye nolunqamlezayo lunokuba lukhuni, emva kwenyikima, isakhiwo sesikolo esomelezwa kunye nayo, kwaye emva koko wadibana nenqanaba lesi-6 emva kwenyikima ngaphandle kweentanda ezintsha. | njengesakhiwo esixhotyiswe “ngemithombo efunxa ukothuka” |
ugxininiso:ukwakhiwa kufuneka kusetyenziswe ukuhambelana nodaka lwepolymer! Ummelwane usetyenziswe ngempazamo udaka oluqhelekileyo, olukhokelela ekuqinisweni kweegubhu kunye nokuwa - njengokusetyenziswa kweglue ukunamathela kwiglasi, iglue ayilunganga ngokulingana nenkunkuma yomsebenzi.
Ukusuka kwisiXeko esiNgavumelekanga ukuya kwiBhulorho yoLwandle oluMnqamlezo: Litshintsha iHlabathi ngokuzolileyo
- I-"Bandage engabonakaliyo" yeLifa leMveli yeNkcubeko kunye neZakhiwo zaMandulo:
I-Beyer Bau, isakhiwo esinenkulungwane yakudala kwi-Technische Universität Dresden eJamani, yayifuna ukomelezwa ngokukhawuleza ngenxa yokwanda kwemithwalo, kodwa yayiphantsi kwezithintelo ezazibekwe kukhuseleko lwelitye lesikhumbuzo. Iinjineli ezine-6mm ezityebileyo ngelaphu le-carbon fiber mesh + umaleko obhityileyo wodaka, ezantsi komqadi “uncamathelise” umaleko we “transparent band-aid”, kungekuphela nje ukuze amandla okuthwala umthwalo aphucule i-50%, kodwa akazange atshintshe isakhiwo ngenkangeleko encinci yasekuqaleni, kwaye neengcali zeBhodi yeLifa leMveli ziye zancoma isakhiwo esidala: ".
- Ubunjineli bezendlela "super patch":
IFlorida, eUnited States, i-cross-sea bridge columns, iqiniswe ngelaphu le-carbon fiber mesh ngo-2003, amandla avela "ababuthathaka" anyuka ngama-420%, kwaye ngoku kwiminyaka engama-20 kamva, iinkanyamba zisezinzile njengentaba eselunxwemeni. Iprojekthi yasekhaya yaseHong Kong-Zhuhai-Macao Bridge kwisiqithi setonela, nayo isetyenziselwe ngokuzolileyo ukwenza ulwakhiwo lolwakhiwo, ngokuchasene nokhukuliseko lwamanzi olwandle.
- "Isixhobo somlingo esibuyisela umva iminyaka" esincinci esidala kunye nesigugileyo:
Kwindawo ye-80's ebumelwaneni eBeijing, amacwecwe omgangatho ayeqhekeke kakhulu, kwaye isicwangciso sokuqala yayikukuwisa kwaye kwakhiwe kwakhona. Kamva ngelaphu le-carbon fiber mesh + i-polymer mortar reinforcement, ixabiso kwi-square meter nganye yi-yuan engama-200 kuphela, kunokwakhiwa kwakhona kwe-80% yeendleko zokulondoloza, kwaye ngoku abahlali bathi: "Yiva indlu incinci iminyaka engama-30!
Ikamva lilapha: Ukuziphilisa, ukubeka iliso “izixhobo ezikrelekrele” zisendleleni
- "Ugqirha oziphilisayo" kwikhonkrithi:
Iingcali zenzululwazi ziphuhlisa i-carbon fiber mesh "eziphilisayo" - xa i-microcracks ivela kwisakhiwo, i-mesh ingasetyenziselwa ukuqinisa. - Xa i-microcracks ibonakala kwisakhiwo, ii-capsules kwizinto eziphathekayo zikhupha ii-agent zokulungisa ezizalisa ngokuzenzekelayo iintanda. Uvavanyo kwilebhu yase-UK lubonise ukuba izinto eziphathekayo zinokwandisa ubomi bekhonkrithi ukuya kuthi ga kwiminyaka engama-200.
- “Isacholo sezempilo” sezakhiwo:
ifakela izinzwa zefiber-optic kwicarbon fiber mesh, njenge "i-smart watch" yezakhiwo: isakhiwo esiphawulekayo e-Shanghai sisisebenzisa ukubeka iliso kwi-settlement kunye nokuqhekeka ngexesha langempela, kwaye idatha idluliselwa ngokuthe ngqo kwi-ofisi yangemuva yolawulo, ephindwe ka-100 ngokufanelekileyo kunokuhlolwa kwendabuko. Isebenza ngokuphindwe ka-100 kunohlolo lwezandla lwemveli.
Iingcebiso ezinenkathalo kwiinjineli nakubanini
1. Izinto eziphathekayo khetha echanekileyo, kabini isiphumo kunye nesiqingatha somzamo:qaphela iimveliso ngamandla okuqina ≥ 3400MPa kunye nemodyuli yokuqina ≥ 230GPa, kwaye unokucela abavelisi ukuba banikezele ngeengxelo zovavanyo.
2. Musa ukonqena ukwakha:umgangatho wesiseko kufuneka ucocwe ucocekile, kwaye udaka lwepolymer kufuneka luxutywe ngokomlinganiselo.
3. Okuphambili kulungiso lwesakhiwo esidala:xa kuthelekiswa nokudilizwa kunye nokwakhiwa kwakhona, i-carbon fiber mesh reinforcement inokugcina inkangeleko yokuqala yesakhiwo, kodwa iphinde igcine ngaphezu kwe-60% yeendleko.
Ukuqukumbela
Xa izinto ze-aerospace "zihla emhlabeni" ukuya kwintsimi yokwakha, ngokukhawuleza sifumene: ukuqiniswa kwasekuqaleni akunakudinga ukwenza imizamo emikhulu, isakhiwo esidala sangaphambili sinokuba "ukukhula umva".Ilaphu le-carbon fiber meshifana ne "superhero" kwishishini lokwakha, kunye neempawu ezikhanyayo, ezinamandla kunye nezizinzileyo, ukuze zonke izakhiwo ezidala zibe nethuba lokuhlaziya ubomi balo - kwaye oku kunokuba sisiqalo sokuguqulwa kwezinto eziphathekayo.
