Ma aloyi azitsulo apamwamba komanso apamwamba, zinthu za ceramic ndi zowonjezera za konkriti | Mtengo wa RBOSCCO
1. Kapangidwe ka Mankhwala a Titanium Dioxide 1.1 Kodi Titanium Dioxide ndi chiyani? Titanium dioxide (TiO₂), dzina lomwe limapezekanso m'magulu asayansi ndi mafakitale, ndi gulu losunthika lokhala ndi mbiri yakale…
M'dziko lamphamvu la polyvinyl chloride (PVC) kupanga, kukwaniritsa kukhazikika kwamafuta ndi mwala wofunikira kwambiri wazogulitsa. PVC, ngakhale imasinthasintha, imadziwika bwino ndi kutentha, komwe nthawi zambiri imanyoza ...
1. α gawo Silicon Carbide, β Phase Silicon Carbide: The Chemical Structure 1.1 Kodi α-Phase Silicon Carbide ndi chiyani? αPhase silicon carbide (SiC) ndi imodzi mwazinthu zokhazikika komanso zofufuzidwa kwambiri za…
M'malo omwe akusintha nthawi zonse azinthu zamafakitale, nanoultrafine molybdenum disulfide (MoS2) yakhala njira yatsopano yopangira mafuta odzola ndi antiwear. Zinthu zotsogola izi, zochokera ku kapangidwe kake ka molybdenum disulfide,…
1. Ponena za Airgel 1.1 Kodi Aerogel ndi chiyani? Aerogel, yomwe nthawi zambiri imayamikiridwa ngati "chinthu chopepuka kwambiri m'malo akuya," ndi nanomaterial yapamwamba kwambiri yomwe imatsutsana ndi zomwe wamba zimayembekezera pakuchulukira komanso kulimba. Yochokera…
Gawo lamagetsi adzuwa likuthamangira mtsogolo momwe magetsi oyera amakhala otsika mtengo komanso odalirika kwambiri. Pakati pa makina osindikizira awa, ufa wa nano-silicon wakhala wosintha masewera, ukupereka nyumba zogona kapena zamalonda ...
Mumlengalenga wokulirapo wa nyenyezi wa sayansi ya zinthu, zida zatsopano zikupitilirabe, zomwe zikubweretsa mbandakucha ku chitukuko cha magawo osiyanasiyana. Mwa iwo, Ti₃AlC₂, ngati nthumwi yodziwika bwino ya MAX…
Mukuyerekeza kotsatiraku kwa silicon carbide ndi silicon nitride ceramics, tifotokoza mwadongosolo kusiyana kwakukulu pakati pa ziwirizi kuchokera ku miyeso itatu: katundu wakuthupi, mankhwala, ndi minda yogwiritsira ntchito.
M'gawo la sayansi yazinthu, alumina yozungulira ikuwonekera pang'onopang'ono ngati chidwi m'mafakitale ambiri. Ndi chitukuko chofulumira cha sayansi ndi ukadaulo, kufunikira kwa zida zogwira ntchito kwambiri kukukulirakulira.…
Silicon Nitride (Si₃N₄) ndi Aluminium Nitride (AlN) midadada ya ceramic onse ndi zida zadothi zotsogola zomwe zimapambana kwambiri m'malo otentha kwambiri monga kutentha kwambiri, dzimbiri, komanso katundu wambiri chifukwa cha thupi lawo labwino kwambiri…
Pazinthu zambiri zapamwamba, silicon nitride ndi boron nitride (BN) ma shafts a ceramic akutuluka ngati oimira ochita bwino kwambiri ndipo amagwiritsidwa ntchito kwambiri m'mafakitale ambiri okhala ndi zinthu zofunika kwambiri ...
Machubu a zirconia ceramic amapangidwa kuchokera ku ufa wa zirconia wonyezimira ndi kutentha kwambiri. Zirconia (ZrO₂) nthawi zambiri imakhala yoyera, yopanda fungo komanso yopanda kukoma yokhala ndi kachulukidwe kakang'ono ka 5.85, malo osungunuka ...
