Umxholo oneenkcukacha
1. IiPropati zoMzimba eziSisiseko zeMolybdenum kunye nokubaluleka koShishino
Imolybdenum esulungekileyo, njengentsimbi yotshintsho, ikwindawo engenakuphinda ithathelwe indawo kwimizi-mveliso yanamhlanje ngenxa yeempawu zayo ezikhethekileyo{0}}zobushushu obuphezulu kunye nokuzinza kweekhemikhali. Indawo yokunyibilika ye-molybdenum ecocekileyo ye-2,617 degree, nangona ingaphantsi kune-tungsten, isebenza njengeendleko ezingaphezulu{4}}ezingenye esebenzayo kwizicelo ezilinganayo{5}}zobushushu obuphezulu.
Iimpawu eziphambili zomzimba ze-molybdenum ecocekileyo ziquka:
(1) Ubuninzi be-10.2 g/cm³, malunga ne-50% ikhaphukhaphu kune tungsten;
(2) I-coefficient yokwandisa i-Thermal ye-5.3×10⁻⁶/K, iphantsi kwaye ithandeka kwizicelo ezichanekileyo;
(3) I-Thermal conductivity ye-138 W/m·K, imodareyitha phakathi kweentsimbi;
(4) Imodyuli ye-elastic ye-320 GPa, amandla aphezulu.
Ukusuka kumbono weekhemikhali, i-molybdenum ecocekileyo ibonisa ukuxhathisa okuphezulu kwe-corrosion, ukuxhathisa i-asidi kunye nesiseko se-corrosion kwigumbi kunye namaqondo okushisa aphakathi. Oku kuyenza ibe yimathiriyeli efanelekileyo kumashishini anendawo ezonakalisayo njengesinyithi kunye neekhemikhali. Kwangaxeshanye, imolybdenum esulungekileyo izinzile ngokungaqhelekanga kwindawo ye-vacuum kunye ne-inert yegesi, ithintela i-oxidation okanye ukuphendula.
Kumasebe okuthengwa kwempahla ye-B2B, ukuqonda ezi propati zisisiseko yimfuneko yokhetho oluchanekileyo kunye novavanyo lwemathiriyeli ye-molybdenum. Izicelo ezahlukeneyo zineemfuno zokusebenza ezahlukeneyo zemolybdenum esulungekileyo; ukuthengwa kwempahla okungaboniyo kunokubangela inkcitho yeendleko okanye ukusebenza okungonelanga.
2. Ulwahlulo lweMolybdenum yobuGcisa ecocekileyo kunye neendlela zokukhetha
I-molybdenum ecocekileyo yahlulahlulwe ngokweendidi ezininzi ezichazwe kusetyenziso kunye nebakala lobunyulu:
【IBanga loBusulungekileyo】 Ngokwemigangatho yamazwe ngamazwe (ASTM B385), i-molybdenum ecocekileyo yahlulahlulwe kwi-99.9%{4}}99.99% kunye namanye amanqanaba ahlukeneyo okucoceka. Ephakamileyo -i-molybdenum ecocekileyo (99.99%+) ye-semiconductors kunye nezicelo zevacuum zibiza ngaphezulu; ngokubanzi -ucoceko lwe-molybdenum (99.9%) ye-metallurgical kunye ne-chemical applications inika uqoqosho olungcono. Ukukhetha kufuneka kuhambelane neemfuno ezichanekileyo zococeko, kuthintelwe inkcitho yeendleko ezichazwe ngaphezulu.
