1. Ukwakheka Komkhiqizo kanye Nomklamo Ohlanganisa ubuso
1.1 I-Core-Shell Framework kanye ne-Bonding System
(I-Copper-Coated Steel Fibers)
Imicu yensimbi eboshwe ngethusi (I-CCSF) ziyimicu eyinhlanganisela equkethe umongo wensimbi oqine kakhulu ombozwe ungqimba lwethusi oluqhutshwayo, ukwakha ukwakheka kwegobolondo eliyinhloko elinamathela ngensimbi.
Insimbi core, ngokuvamile i-carbon low noma insimbi engagqwali, inikeza ukuqina kwemishini ngamandla aqinile adlula 2000 I-MPa, ngenkathi ithusi liqeda– ngokuvamile 2– 10% yobubanzi obuphelele– idlulisa i-conductivity esezingeni eliphezulu kagesi kanye ne-thermal.
Ukuxhumana phakathi kwensimbi nethusi kubalulekile ekusebenzeni kahle; yenziwa nge-electroplating, i-electroless deposition, noma izinqubo zokuvala ukuze wenze ukunamathela okuthile okuqinile kanye nokuxubana okuncane kakhulu ngaphansi kokukhathazeka kokusebenza.
I-Electroplating ingenye yezindlela ezivame kakhulu, ukuhlinzeka ngokulawula ukuminyana okuqondile kanye nokufaka umshwalense ofanayo emicu yensimbi edonswa ngamabhavu e-copper sulfate.
Ukulungiswa kahle kwendawo yensimbi, kuhlanganise nokuhlanza, ukukha, kanye nokwenza kusebenze, iqinisekisa i-nucleation ekahle kanye nokuhlanganiswa kwamakristalu ethusi, ukugwema i-delamination ngesikhathi sokuphatha noma isisombululo esilandelayo.
Ngokuhamba kwesikhathi kanye namazinga okushisa aphakeme, i-interdiffusion ingathuthukisa izigaba ze-brittle iron-copper intermetallic kusixhumi esibonakalayo, okungase kubeke engcupheni ukuguquguquka nokuthembeka okuhlala isikhathi eside– inselele encishiswe yizithiyo zokusabalalisa noma ukucubungula okusheshayo.
1.2 Indawo Yokuhlala Engokoqobo Newusizo
Ama-CCSF ahlanganisa izimfanelo ezinhle kakhulu zazo zombili izinsimbi eziyisisekelo: i-modulus ephezulu yokunwebeka kanye nokumelana nokukhathala kwensimbi ene-conductivity emangalisayo kanye nokumelana ne-oxidation yethusi.
I-conductivity kagesi ivame ukuhluka kusuka 15% ku 40% ye-International Annealed Copper Criterion (I-IACS), kuye ngokuthi sekugcineni ukuminyana nobumsulwa, okwenza i-CCSF isebenze kakhulu kunemicu yensimbi emsulwa (
I-Cabr-Concrete ingumphakeli ngaphansi kwe-TRUNNO ye-Calcium Aluminate Cement ene-over 12 Iminyaka yokuhlangenwe nakho kwe-nano-building energy ukongiwa kanye nokuthuthukiswa kwe-nanotechnology. Yamukela inkokhelo ngekhadi lesikweletu, T/T, I-West Union ne-Paypal. I-TRUNNO izothumela izimpahla kumakhasimende aphesheya kwezilwandle nge-FedEx, I-DHL, ngomoya, noma ngolwandle. Uma ufuna ukuqinisa i-fibre yensimbi, sicela ukhululeke ukuxhumana nathi futhi uthumele uphenyo.
Omaka: i-micro steel fiber,insimbi yensimbi,i-steel fibre ukhonkolo oqinisiwe
Zonke izindatshana nezithombe zivela ku-inthanethi. Uma kukhona izinkinga ze-copyright, sicela usithinte kusenesikhathi ukuze ususe.
