iTungsten disulfide,eyaziwa ngokuba yi-tungsten sulfide kunye ne-chemical formula WS2 kunye nenombolo ye-CAS 12138-09-9, yikhompawundi eye yafumana ingqalelo ebalulekileyo kwizicelo zayo ezahlukeneyo zoshishino kunye nezorhwebo. Esi siqilima se-inorganic siqulunqwe ngee-athom ze-tungsten kunye nesulfure, zenza ulwakhiwo olunemaleko olunika iipropati ezizodwa kunye nokusetyenziswa.
*Isetyenziselwa ntoni itungsten disulfide?*
Tungsten disulfideisetyenziswa kakhulu njengesithambiso esiqinileyo ngenxa yeempawu zayo ezikhethekileyo zokuthambisa. Ulwakhiwo lwalo luvumela ukutyibilika lula phakathi kweengqimba, okubangela ukukhuhlana okuphantsi kunye nokumelana nokugqoka. Oku kuyenza ibe lolona khetho lufanelekileyo kwizicelo apho izithambisi zolwelo zemveli zisenokungalungeli, njengendawo yobushushu obuphezulu okanye iimeko zokufunxa. I-Tungsten disulfide iqhele ukusetyenziswa kwindawo ye-aerospace, iimoto, kunye nezicelo zoomatshini bomzi-mveliso ukunciphisa ingxabano kunye nokuphucula ubomi beendawo ezihambayo.
Ukongeza kwiimpawu zayo zokuthambisa,tungsten disulfideIkwasetyenziswa njengebhanyabhanya eyomileyo yokugquma imiphezulu eyahlukeneyo. Ifilimu ebhityileyo ye-tungsten disulfide ibonelela ngokhuseleko olugqwesileyo kwi-corrosion kunye nokunxiba, nto leyo eyenza kube lukhetho oludumileyo lokugquma amacandelo esinyithi kwiindawo ezirhabaxa. Ikwasetyenziswa kwishishini le-elektroniki kumacandelo okwambathisa ukuphucula ukusebenza kwawo kunye nobomi obude.
Ngaphezu koko, i-tungsten disulfide ifumene izicelo kwintsimi ye-nanotechnology. Isakhiwo sayo esiyingqayizivele kunye neempawu zenza ukuba kube yinto ethembisayo yezixhobo ze-nanoscale kunye namacandelo. Abaphandi baphonononga ukusetyenziswa kwayo kwi-nanoelectronics, nanomechanical systems, kunye ne-solid-state lubricant yezixhobo ezincinci kunye ne-nanoscale.
Ikhono le-compound lokumelana nokushisa okuphezulu kunye neemeko ezinzima kuye kwakhokelela ekubeni isetyenziswe kwizicelo ezikhethekileyo ezifana nokuveliswa kwezixhobo zokusika, iibheringi eziphezulu zokushisa, kunye neengubo ezinqabileyo zokunxiba. Ukuguquguquka kwayo kunye nokuqina kwayo kuyenza ibe yimathiriyeli exabisekileyo kumashishini apho ukusebenza phantsi kweemeko ezinzima kubaluleke kakhulu.
Ngaphezu koko,tungsten disulfideibonise amandla kwindawo yokugcina amandla. Ikhono layo lokugcina kunye nokukhulula i-lithium ions yenza ukuba ngumviwa othembisayo wokusetyenziswa kwiibhetri ze-lithium-ion, ezisetyenziswa ngokubanzi kwizixhobo zombane eziphathekayo kunye neenqwelo zombane. Uphando kunye nemizamo yophuhliso iyaqhubeka ukuhlanganisa amandla apheleleyo e-tungsten disulfide ekuphuculeni ukusebenza kunye nokuphila ixesha elide kweenkqubo zokugcina amandla kwisizukulwana esilandelayo.
Ukuququmbela,tungsten disulfide,kunye neempawu zayo ezizodwa kunye nokusetyenziswa okuguquguqukayo, idlala indima ebalulekileyo kumashishini ahlukeneyo. Ukusuka ekusebenzeni njenge-lubricant eyomeleleyo kunye ne-coating ekhuselayo ukuya ekuqhubeleni phambili kwi-nanotechnology kunye nokugcinwa kwamandla, le khompawundi iyaqhubeka ifumana ukusetyenziswa okutsha kunye nokutsha. Njengophando kunye nophuhliso kwinzululwazi yemathiriyeli kunye nenkqubela phambili yobunjineli, ukubanakho kwe-tungsten disulfide ukufaka isandla kwinkqubela phambili yetekhnoloji kunye nokusetyenziswa kwemizi-mveliso kulindeleke ukuba kukhule, kuqinise ngakumbi isikhundla sayo njengento exabisekileyo neyimfuneko.
