I. Ukuba nokwenzeka kokusetyenziswa kwelaphu leTeflon kwiiFurnaces zoKujikeleza koMoya oHotyo
1. Isetyenziswa njenge-cushion engagxili kwiinkqubo zobushushu obuphantsi
Xa iqondo lobushushu leziko lilawulwa ngokungqongqo ngaphantsi kwe-260°C (umzekelo, ukomisa iqondo eliphantsi lobushushu, ukususwa kwe-binder, kunye nokunyanga uludaka), Ilaphu leTeflon elinobushushu obuphezulu linokubekwa kwiibhanti zemesh okanye iitreyi zezinto eziphathekayo. Ipropathi yayo egqwesileyo yokungancamatheli yenza ukuba kube lula ukudiliza izixhobo zokusebenza ngaphandle kokuncamathelisa okushiyekileyo, kuphucula kakhulu ukusebenza kakuhle kokuchola.
2. Ithintelwe ngokungqongqo kwiimeko zobushushu obuphakathi kunye nobushushu obuphezulu
Iziko lokujikeleza komoya oshushu lidla ngokusebenza kuma-300°C ukuya kuma-950°C. Izinto eziphathekayo zeTeflon zibonisa umda wokumelana nokushisa okuqhubekayo kwe-260 ° C kuphela kunye nokunyamezela kwexesha elifutshane le-300 ° C. Yakuba ishushu kakhulu, i-PTFE ibola ngokukhawuleza kwaye ikhuphe iigesi ezinetyhefu ephezulu njengehydrogen fluoride kunye ne-perfluoroisobutylene, etshayela izixhobo eziko kwaye ibangele iingozi eziyingozi zetyhefu. Ilaphu leTeflon linqatshelwe ngokungqongqo kuzo zonke iinkqubo ze-sintering ezisemthethweni.
3. Umgaqo wokhuseleko olungaxoxisiyo
Owona mgangatho wokugweba uqinisekisiweyo ngabavelisi belaphu lobushushu obuphezulu beTeflon eJiangsu lolona bushushu buphezulu kuyo yonke inkqubo. Ukuba ukushisa kwesithando somlilo akucaci okanye akunakuqinisekiswa ngaphantsi kwe-260 ° C, ukusebenzisa ilaphu akukhuthazwa naphantsi kwaziphi na iimeko. Akukho msebenzi unobungozi uya kwenziwa ngokusekelwe kumava angaqinisekanga.
II. Iimpawu eziphambili zeTeflon High-Temperature Lath
1. Umda ocacileyo wokumelana nobushushu
Yenziwe ngokufakela ilaphu lesiseko se-fiberglass kunye ne-PTFE, ilaphu linikeza uluhlu oluqhubekayo lokumelana nokushisa kwe--70 ° C ukuya kwi-260 ° C kunye nokuchasana kwexesha elifutshane ukuya kwi-300 ° C. Esi sibonakaliso sobugcisa esiqinileyo sichaza umda waso osebenzayo kuphela kwiinkqubo zokushisa okuphantsi kwaye kukhokelela ekungaphumeleli ngokukhawuleza xa umda weqondo lokushisa ugqithisiwe.
Phantse akukho nto inokubambelela ngokuqinileyo kumphezulu wayo, nto leyo evumela ukuxobuka okucocekileyo kweentlaka, iiglu nee-inki. Ixhathisa i-asidi ezomeleleyo, i-alkalis eyomeleleyo, kunye nezinyibilikisi zendalo, kunye nemithombo yeendaba ezonakalisayo ezimbalwa njengesinyithi esinyibilikisiweyo sealkali, i-high-temperature fluorinating agents, kunye ne-aqua regia ekwazi ukuyonakalisa.
3. Iimpawu ezigqwesileyo zombane kunye nezomatshini
Ngamandla aphezulu e-dielectric, isebenza njengento efanelekileyo yokufakelwa kombane. I-coefficient yayo ye-friction isezantsi malunga ne-0.04, iyenza ifanelekele usetyenziso lwecandelo lokutyibilika. Isiseko se-fiberglass sibonelela ngamandla aphezulu kunye nokuzinza komda, kunye nelaphu linokwenziwa ngokwezifiso libe kwizakhiwo eziphefumlayo okanye ezomeleleyo.
1. Ukuphuculwa kwesiphumo sokudiliza kunye nococeko lwemveliso
Ilaphu linqanda i-workpieces ukuba ingadibanisi neetreyi, iqinisekisa umgangatho ogudileyo kunye nemveliso yemveliso, ukunciphisa amaxabiso okulahlwa, kunye nokwenza lula ukucocwa kwezixhobo. Inika iziphumo ezibalaseleyo kumacandelo amancinci anemilo enzima okanye ukuthambekela kokunamathela okuphezulu.
2. Impembelelo ekuqhubeni ubushushu kunye nokuhanjiswa komoya
Ilaphu leTeflon libonisa ukuhanjiswa kwe-thermal ephantsi kunye nokugcinwa kobushushu obuphantsi, obucothisa ukunyuka kweqondo lobushushu emazantsi ezinto zokusebenza kwaye kufuna ixesha elandisiweyo lokugcinwa kobushushu. Ilaphu leTeflon eliphefumulayo livumela ukungena komoya oshushu kunye nokuphazamiseka okuncinci kokufana kweqondo lokushisa, ngelixa ilaphu eliqinileyo lithintela ukuhamba komoya kwaye libangela ngokulula ukungafani kobushushu bendawo, efuna ukuqinisekiswa okufanayo ngaphambi kokusetyenziswa ngokusesikweni.
3. Iingozi ezinokubakho zokhuseleko
Ukubola ngokugqithisileyo ngowona mngcipheko ubalulekileyo. Iigesi ezibolileyo ze-fluoride azinambala kwaye ziyityhefu kakhulu, kwaye ukuphefumla izixa zomkhondo kunokubulala. Izixhobo kufuneka zixhotyiswe ngolawulo oluchanekileyo lobushushu, i-alam ezimeleyo yobushushu obugqithisileyo, kunye neenkqubo zokuphefumla ngenkani. Umsebenzi ongajongwanga uthintelwe ngokungqongqo.
IV. Imigaqo yokusetyenziswa okunyanzelekileyo kunye neengcebiso
1. Ukuqinisekiswa kweqondo lokushisa kwangaphambili
Abavelisi belaphu leJiangsu Teflon yobuchwephesha bakhumbuza abasebenzisi ukuba baqinisekise ubushushu obuphezulu bokusebenza kunye nenkqubo epheleleyo yobushushu begophe lesithando somlilo phambi kokusetyenziswa, qinisekisa ukuba ubushushu abusoze budlule kwi-260°C, kwaye bagcine iirekhodi ezipheleleyo.
2. Gqibezela ulungelelwaniso lokhuseleko
Faka ii-alam zobushushu bokukhanya kwesandi kunye kunye nezixhobo zokucima umbane ngokungxamisekileyo ukuqinisekisa ukungena komoya okusebenzayo. Abanini-zithuthi kufuneka balawule iinkqubo zokusabela kwimeko kaxakeka kwaye baxhotyiswe ngezixhobo ezisemgangathweni zokhuselo.
3. Ukukhethwa okuphambili kwesakhiwo esiphefumulayo
Ukunciphisa ukuphazamiseka kokujikeleza komoya oshushu, ilaphu leTeflon eliphefumlayo liyacetyiswa kakhulu. Gxila rhoqo umphezulu welaphu ukubona ukujika kombala, ukugquma, kunye nomonakalo, kwaye uyeke ukusebenzisa kwaye ubuyisele iimveliso ezonakeleyo ngokukhawuleza xa kufunyenwe izinto ezingaqhelekanga.
