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 wokuvelisa sebenzisaisiguquli samaxesha amaninziokanyeiservomotortochanekileyoyalungisaisantya sokutsalwa,ixesha lokwenyani litshintsha ngexesha elinye.
Lubeke phambili uhlengahlengiso olukhawulezileyo: Iqondo lobushushu linobushushu obuphezulu. Ngexesha lemveliso ezinzileyo, iqondo lobushushu kufuneka lilungiswe, kunye nemigca ekhawulezayo kufuneka isebenze ngeyona ndlela isebenzayo'kwangexesha.'Xa i-tuningis ifuneka ngokufanelekileyo, uhlengahlengiso lwesantya kufuneka lubekwe phambili.
II.UkuchazaIiSetingi zeZowuni eziFanelekayo
Sebenzisa350°Castheeffectivesinteringthreshold: PTFEmeltsataimalunga nama327°C, kodwa umgangatho wommandla womhlaba udinga370–395°C. Ngoko ke, lo mmandla ungaphezulu kwama-350°Cisdecdectives theeffectives interingthreingthres.Kuphela ngexesha leefabricslichitha ixeshanakwixesha elingaphezulu kwelo.
Ukusasazwa kobushushu bezonete ezininzi: Indawo yokufudumeza (100–250°C)–isusa inkqubo yokusebenza kwaye ithintele ukugqabhuka;Izowuni ye-Sintering(360–395°C)–iphumeza ukunyibilika;izowuni yokuseta lobushushu obuphezulu(380–390°C)–ukunciphisa uxinzelelo lwangaphakathi;izowuni yokupholisa30ibaliixesha 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 ezilula (0.08–0.13mm)–30–60imizuzwana;Iintlobo eziqhelekileyo(0.18–0.25mm)–1.5–3imizuzu;Uhlobo olunzima(0.35mmanda ngaphezulu)–3–5 umzuzu owongezelelekileyo,kunyanyekelweukuthintela”kuphekwa ngaphandle, ecaleni komlambo.
Uchongo kunye nohlengahlengiso: Ukungoneli kokungaphakathi(amandla aphantsi, ukuchithwa komgubo, iintanda ezincinci)→ukunciphisa isantya ukuya kwixesha elandiswayo;Ukuntywila ngokugqithisileyo(mthubi,ubuqhophololo,umphunga omhlophe ocaphukisayo)→ukunyusa isantyaukutshotshotshotshotshozela ubushushu 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, ongeyiyo inkozo; umthubi ubonisa ukuba shushu-ngapha, 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-ukulungisa 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 esisetyenziswayongangexesha lokwenyani elinokulawulwa.
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 lelaphu ngaphezulu kwe350°Cngefestile ehambelanayobungqingqwa bemveliso, kunye nokusebenzisa umgangatho wokuhlola iziphumo zokulungiswa kwe-loop evaliweyo.
