I.Adjusting the FabricTravelSpeed:TheCoreControlMethod
Ubudlelwane phakathi kwexesha kunye nexesha: Sinteringtime(s)=effectiveheatingsectionlengthoftheoven(m)÷fabrictravelspeed(m/s).Umzekelo,ukuba icandelo elisebenzayo15mandthelinespeedis5m/mi n,ixesha yimizuzu emi-3.Umgca wemveliso sebenzisa irequencyconvertersorservomotortopreciselyalungisa isantya sokutsalwa kwe-roller,ivumela-ixesha lokwenyanikwixesha eliphakathi.
Lubeke phambili uhlengahlengiso olukhawulezileyo: Iqondo lobushushu linobushushu obuphezulu. Ngexesha lemveliso ezinzileyo, iqondo lobushushu kufuneka lilungiswe, kwaye isantya kufuneka sisebenze ngeyona ndlela isebenzayo'ngexesha.'Xa i-tuningis ifuneka ngokufanelekileyo, uhlengahlengiso lwesantya kufuneka lubekwe phambili.
II.UkuchazaIiSetingi zeZowuni eZisebenzayo
Sebenzisa350°Castheeffectivesinteringthreshold: PTFEmeltsata malunga nama327°C,kodwa umphakamo wommandla womhlaba udinga370–395°C. Ngoko ke, lo mmandla ungaphezulu kwama-350°Cisdecdectives theeffectives interingthreingthres.Kuphela ngexesha leefabricslichitha ixeshanakwixesha elingaphezulu kweli xesha.
Ukusasazwa kobushushu bezonete ezininzi: Indawo yokufudumeza (100–250°C)–isusa inkqubo yokucutshungulwa kwaye inqanda ukugqabhuka;Izowuni ye-Sintering(360–395°C)–iphumeza ukunyibilika;izowuni yokuseta ubushushu obuphezulu(380–390°C)–indawo yokupholisa yangaphakathi(indawo yokupholisa300ibaliixesha eliphantsi).
Ukubala ixesha lokuhlala elisebenzayo:Yahlula-ixesha elipheleleyo lilonkethofallzonessetat≥350°Cbythelinespeed.Umzekelo,ukuba ubude bubonke ngamacandelwana angaphezu kwama-350°Cis10mandthespeedis4m/min,esebenza ngexesha lokuphumla yi2.5minutes.
III.IiNkcazo zeMvelisoDetermineTargetTimeandAdjustments
Amaxesha oReferensi (at380–390°C): Iindidi eziKhaphukhaphu (0.08–0.13mm)–30–60imizuzwana;Iintlobo eziqhelekileyo(0.18–0.25mm)–1.5–3imizuzu;Uhlobo olunzima(0.35mmanda ngaphezulu)–3–5imizuzu isolotyana elide,kunyanyekelweukuthintela”kuphekwa ngaphandle, ecaleni.
Uchongo kunye nohlengahlengiso: Ukungoneli kokungaphakathi(amandla aphantsi, ukuchithwa komgubo, iintanda ezincinci)→ukunciphisa isantya ukuya kwixesha elongeziweyo;Ukuntywila ngaphezulu(mthubi,ubumdaka,umphunga omhlophe orhawuzelayo)→ukunyusa isantyaukutshotshotshotshotshozela ubushushu bobushushu obuphezulu.
Iqondo lobushushu-ixesha elilinganayo utshintshiselwano: Ubushushu bobushushu obuphezulu (395–405°C, amashumi amabini emizuzwana, umngcipheko ophezulu) okanye ubushushu obuphantsi bucotha ukubaleka phakathi (360–375°C,5–8imizuzu, ubulunga obuzinze ngakumbi) zombini zinokwenzeka.
IV.QualityClosed-LoopControlandKeyPrecautions
Ukuhlolwa komgangatho: Iimveliso ezineziqinisekiso zibonakala ngathi zimhlophe zimhlophe kwaye ziguquguqukile, ezinomphezulu ogudileyo, ongengowokutya okuziinkozo; umthubi ubonisa ukujika-jika okungaphaya, ngeli lixa umgubo wepoda okanye umgubo womgubo ubonisa ukuba sezantsi-sintering. Rhoqo ukuvavanya amandla epeel;ayonelanga, acutha isantya nge3–5% ukuya kububanzi obukhulu. ixesha.Ukuba ukuqinisa olu lwanele kodwaifabricisbricisbrittle,ibeka phambili ilungile-ulungisa iqondo lobushushungelixa ngokufanelekileyo unciphisa ixesha.Sebenzisa ithermometer ekwifraredukujonga ilaphu ngaphezulu kweqondo lobushushuukuqinisekisa ukuba ixesha lokuhlala lingaphezulu kwe350°Clidibana nemfuneko.
Ulawulo oluvaliweyo: Misela isantya esivaliweyo'ulungiselelo lwesantya/ubushushu→umgangatho wokujonga impendulo→ulungiso.'Ubushushu bufanele ukulungelelana ngokomlinganiselo, ngesantya esisetyenziswayo njengakwenyani-ixesha elilawulekayo.
Izithintelo ezibalulekileyo: I-PTFE idiza ngaphezulu kwe-415°C,ikhupha iigesi eziyityhefu;ihlala ixesha elidengaphezu kwama-400°kwalelwe ngokungqongqo.Isityhilelo sobushushu obuphezulu yonakalisa iglassfibersizin i-gagent, ekhokelela ekunyukeni kokuqina kwesiseko sefabri.Emva kokuhlangana, ukupholisa kwi-300–250°Ccrystallizationzonendawo kufuneka ilawulweukuqinisekisa ukuguquguquka kokugquma.
Isishwankathelo: Ngokusekwe kwiisetingi zobushushu bezonete ezininzi, kunye nesantya sefabrictravelsiparamitha yolungelelwaniso, lawula ngokuthe ngqoixesha elisebenzayo lokuhlala kwilaphu ngaphezulu kwe350°Cngefestile ehambelanayobungqingqwa bemveliso, kunye nokusebenzisa umgangatho wokuhlola iziphumo zokulungiswa kwe-loop evaliweyo.
