Yintoni iMolybdenum disulfide?
I-Molybdenum disulfide (i-MoS2) sisithambiso esibalulekileyo esiqinileyo, eyaziwa ngokuba "yinkosi yokuthambisa okuqinileyo"
1. I-Molybdenum disulfide ngumgubo oqinileyo owenziwe kwi-molybdenum concentrate powder yendalo emva kokucocwa kweekhemikhali.
2. Umbala wemveliso umnyama kwaye ungwevu kancinci, kunye ne-metallic luster, kwaye uzive utyibilika xa uphathwa, kwaye awunyibiliki emanzini.
3. Imveliso ineenzuzo zokusasazwa kakuhle kunye nokungabophi. Inokongezwa kwiigrisi ezahlukahlukeneyo ukwenza i-colloidal state engabopheleli, ukwandisa i-lubricity kunye noxinzelelo olugqithisileyo lwegrisi;
4. Kwakhona ifanelekile ukushisa okuphezulu, uxinzelelo oluphezulu, isantya esiphezulu kunye nomthwalo ophezulu weemeko zokusebenza komatshini, kunye nokwandisa ubomi benkonzo yezixhobo;
5. Umsebenzi oyintloko we-molybdenum disulfide esetyenziswa njengezinto ezixubeneyo kukunciphisa ukuxhatshazwa kwiqondo lokushisa eliphantsi, ukwandisa ukuxutywa kwiqondo lokushisa eliphezulu, kunye nokunciphisa ukulahleka komlilo.
Ukusetyenziswa kwe-molybdenum disulfide (MoS2)
1. Ukuthanjiswa phantsi kweemeko ezibanzi zobushushu: uluhlu olusebenzayo lweoli yokuthambisa kunye negrisi malunga ne-60 ° C ukuya kuma-350 ° C. I-molybdenum disulfide lubricant eqinileyo ingasetyenziswa kwi-Operating range yeqondo lokushisa ukusuka kwi-270 ° C ukuya kwi-1000 ° C.
2. Ukuthanjiswa phantsi kweemeko zomthwalo onzima: ngokubanzi, ifilimu yeoli yeoli yokuthambisa kunye negrisi inokuthwala umthwalo omncinci. Emva kokuba umthwalo udlula ixabiso elilinganiselweyo elinokuthwala, ifilimu yeoli iya kuphuka kwaye i-friction surface iya kuluma. Umthwalo ophakathi onokuthi uthwale ifilimu eqinileyo yokuthambisa yi-108Pa.
3. I-Lubrication phantsi kweemeko ze-vacuum: phantsi kweemeko eziphezulu ze-vacuum, i-evaporation ye-oyile yokuthambisa kunye negrisi inkulu kakhulu, ekulula ukuyonakalisa indawo ye-vacuum kunye nokuchaphazela ukusebenza kwamanye amacandelo. Imolybdenum disulfide eqinileyo imathiriyeli yokuthambisa idla ngokusetyenziselwa ukuthambisa.
4. Ukuthanjiswa phantsi kweemeko zemitha: Phantsi kweemeko zemitha, izithambisi zolwelo ngokubanzi ziya polymerize okanye zibole kwaye ziphulukane neempawu zazo zokuthambisa. Izithambiso eziqinileyo zinokuxhathisa okulungileyo kwimitha.
5. Ukuthanjiswa komphezulu ohambisa isilayidi: Umzekelo, ukukhuhlana komgangatho otyibilikayo, onje ngebhrashi yombane yemoto yombane, isilayidi sombane, isilayidi somqokeleli welanga kwisathelayithi eyenziweyo esebenza kwivacuum kunye nokutyibilika kombane, inokuthanjiswa ngezinto ezidityanisiweyo. yekhabhoni yegraphite okanye isinyithi.
6. Iimeko ezineemeko ezimbi kakhulu zokusingqongileyo: Kwiimeko ezinzima zokusingqongileyo, ezifana noomatshini bothutho, oomatshini bobunjineli, amaziko esinyithi kunye nentsimbi kunye nentsimbi, oomatshini bemigodi kunye nezinye iindawo zokuhambisa ezisebenza eluthulini, intlenga, ubushushu obuphezulu kunye nokufuma kunye nokunye okusingqongileyo okurhabaxa. kwiimeko, i-molybdenum disulfide lubricant eqinileyo ingasetyenziselwa ukuthambisa.
6. Imekobume eyonakalisayo: Umzekelo, iindawo zothumelo koomatshini baselwandle kunye noomatshini bekhemikhali basebenza emanzini (umphunga), amanzi olwandle, iasidi, ialkali, ityuwa kunye nezinye izinto eziyingozi, kwaye kufuneka zityhutyhe amanqanaba ahlukeneyo ekhemikhali. Ukuthanjiswa okuqinileyo kweMolybdenum disulfide kungasetyenziselwa iindawo zothumelo ezisebenza kule meko.
7. Iindawo ezineemeko zokusingqongileyo ezicocekileyo kakhulu: iinxalenye zothumelo koomatshini abafana ne-electronics, textiles, ukutya, amayeza, ukwenza iphepha, ukushicilela, njl.
8. Iimeko ngaphandle kokulondolozwa: ezinye iindawo zothumelo azifuni kugcinwa, kwaye ezinye iindawo zothumelo kufuneka zicuthwe amaxesha olondolozo ukuze kongiwe iindleko. Kwezi zihlandlo, ukusetyenziswa kwe-MoS2 ye-lubricant eqinileyo kunengqiqo, kulula kwaye kunokonga imali.
