Umgubo weTungsten Disulfide
Ingcaciso yeMveliso
I-Tungsten disulfide yikhompawundi eyenziwe ngezinto ezimbini, i-tungsten kunye nesalfure, kwaye ihlala ishunqulelwa njenge-WS2.Ngokubhekiselele kwiipropati ezibonakalayo, i-tungsten disulfide yinto emnyama eqinile kunye nesakhiwo se-crystal kunye ne-metallic luster.Indawo yokunyibilika kwayo kunye nobunzima buphezulu, ayinyibiliki emanzini kunye ne-asidi eqhelekileyo kunye neziseko, kodwa inokusabela ngeziseko ezinamandla.Isetyenziswa ngokubanzi kwizinto zokuthambisa, izixhobo zombane, ii-catalysts kunye namanye amacandelo.Njengesithambiso, i-tungsten disulfide isetyenziswa ngokubanzi koomatshini abahlukeneyo kunye nokwenziwa kweemoto ngenxa yeempawu zayo ezibalaseleyo zokuthambisa kunye nokumelana nobushushu obuphezulu be-oxidation.Kwizixhobo zombane, i-tungsten disulfide uzinzo oluphezulu lobushushu kunye nokuqhuba kakuhle kuyenza ibe yeyona nto ifanelekileyo yokulahla ubushushu.Ukongeza, ngenxa yesakhiwo sayo esifana negraphite, i-tungsten disulfide nayo idlala indima ebalulekileyo ekwenzeni ibhetri.Kwintsimi ye-catalysts, i-tungsten disulfide isetyenziswe njenge-catalyst yokubola kwe-methane ngenxa yesakhiwo sayo esikhethekileyo.Kwangaxeshanye, i-tungsten disulfide nayo inamandla okusebenza kwizinto zokwenziwa kwe-superconducting kunye ne-composites.

Isicelo
1) Izongezo eziqinileyo zokuthambisa igrisi
Ukuxuba i-micron powder kunye negrisi kumlinganiselo we-3% ukuya kwi-15% kunokunyusa ukuzinza kobushushu obuphezulu, uxinzelelo olugqithisileyo kunye neempawu ezichasayo zegrisi kunye nokwandisa ubomi benkonzo yegrisi.
Ukusasaza i-nano tungsten disulfide powder kwi-oyile yokuthambisa inokuphucula i-lubricity (ukunciphisa i-friction) kunye neempawu ezichasene ne-anti-wear of lubricating oil, kuba i-nano tungsten disulfide i-antioxidant enamandla, enokwandisa kakhulu ubomi benkonzo yeoli yokuthambisa.
2) Ukuthambisa ukuthambisa
I-Tungsten disulfide powder inokutshizwa phezu kwe-substrate ngomoya owomileyo kunye obandayo phantsi koxinzelelo lwe-0.8Mpa (120psi).Ukutshiza kunokuqhutywa kwiqondo lokushisa kunye ne-coating yi-0.5 micron.Ngaphandle koko, i-powder ixutywe kunye ne-isopropyl alcohol kwaye into enamathele isetyenziswe kwi-substrate.Okwangoku, ukugquma kwe-tungsten disulfide kusetyenziswe kwiindawo ezininzi, ezinje ngezixhobo zemoto, iindawo ze-aerospace, iibheringi, izixhobo zokusika, ukukhutshwa komngundo, iinxalenye zevalvu, ipistons, amatyathanga, njl.
3) I-Catalyst
I-Tungsten disulfide inokusetyenziswa njenge-catalyst kwintsimi yepetrochemical.Iinzuzo zayo kukusebenza okuphezulu kokuqhekeka, umsebenzi ozinzile kunye nothembekileyo we-catalytic, kunye nobomi benkonzo ende.
4) Ezinye izicelo
I-Tungsten disulfide ikwasetyenziswa njengebrashi engeyiyo i-ferrous kushishino lwekhabhoni, kwaye ingasetyenziswa kwizinto eziqinileyo kunye nemathiriyeli ye-welding wire.
