izindaba

Ama-phenolic molding compounds ayizinto zokubumba ezisebenzisa i-thermosetting ezenziwe ngokuxuba, ukuxova, kanye ne-granulating phenolic resin njenge-matrix enezigcwalisi (ezifana nofulawa wokhuni, i-fiber yengilazi, kanye ne-mineral powder), ama-curing agents, ama-lubricant, nezinye izithasiselo. Izinzuzo zawo eziyinhloko zisekuphikeleni kwawo okuhle kakhulu kwezinga lokushisa eliphezulu (izinga lokushisa lokusebenza lesikhathi eside kufika ku-150-200℃), izakhiwo zokushisa (ukumelana nomthamo ophezulu, ukulahlekelwa kwe-dielectric okuphansi), amandla omshini, kanye nokuzinza kobukhulu. Futhi amelana nokugqwala kwamakhemikhali, anezindleko ezingalawuleki, futhi agcina ukusebenza okuzinzile ngisho nangaphansi kwezinga lokushisa eliphezulu, i-voltage ephezulu, noma izindawo ezinomswakama.

Izinhlobo zeIzinhlanganisela Zokubumba Ze-Phenolic 

Izinhlanganisela Zokubumba Ezicindezelwe:Lokhu kudinga ukubumba okucindezelwe. Izinto zifakwa esikhumbeni bese zilungiswa ngaphansi kokushisa okuphezulu kanye nengcindezi (ngokuvamile 150-180℃ kanye no-10-50MPa). Zifanelekela ukukhiqiza izimo eziyinkimbinkimbi, izidingo zokunemba okuphezulu, noma izingxenye ezinkulu, ezinodonga olujiyile, njengezisekeli zokuvikela emishinini kagesi kanye nezingxenye ezingamelani nokushisa ezizungeze izinjini zezimoto. Ngokusakazwa kokugcwalisa okufanayo, imikhiqizo ibonisa amandla aphezulu omshini kanye nokumelana nokushisa okuphezulu, okwenza isetshenziswe kabanzi ezingxenyeni zezimboni eziphakathi nendawo kuya kweziphezulu kanye nohlobo lomkhiqizo olujwayelekile lwendabuko.

Izithako zokubumba ngomjovo:Zifanele izinqubo zokubumba ngomjovo, lezi zinto zinokugeleza okuhle futhi zingagcwaliswa ngokushesha futhi zilashwe emishinini yokubumba ngomjovo, okuholela ekusebenzeni kahle kokukhiqiza okuphezulu kanye nokwenza izinto ngokuzenzakalela. Zifanele ukukhiqizwa ngobuningi kwezingxenye ezincane kuya kweziphakathi, ezakhiwe ngendlela ejwayelekile, njengephaneli yokushintsha izinto zasendlini, izixhumi ze-elekthronikhi zezimoto, kanye nezingxenye ezincane zokufaka ugesi. Ngokuthandwa kwezinqubo zokubumba ngomjovo kanye nokwenza ngcono ukugeleza kwezinto, isabelo semakethe sale mikhiqizo sikhula kancane kancane, ikakhulukazi njengoba sihlangabezana nezidingo zokukhiqiza ezinkulu zemikhiqizo yezimboni yabathengi.

Izindawo Zokufaka IsiceloIzinhlanganisela Zokubumba Ze-Phenolic

Imishini Kagesi/Ye-elekthronikhi:Lesi yisimo esiyinhloko sesicelo, esihlanganisa izingxenye zokufaka izinto zokushisa kanye nezingxenye zesakhiwo semishini efana nama-motor, ama-transformer, ama-circuit breaker, kanye nama-relay, njenge-motor commutator, ama-transformer insulation frames, kanye nama-circuit breaker terminals. Ukufaka izinto zokushisa okuphezulu kanye nokumelana nokushisa okuphezulu kwama-phenolic molding compounds kuqinisekisa ukusebenza okuphephile kwemishini kagesi ngaphansi kwezimo ze-voltage ephezulu kanye nokushisa okuphezulu, okuvimbela ama-short circuits abangelwa ukwehluleka kokufaka izinto zokushisa. Ama-compound okucindezela asetshenziswa kakhulu ezingxenyeni ezibalulekile zokufaka izinto zokushisa, kuyilapho ama-compound okufaka izinto zokushisa afanelekela ukukhiqizwa ngobuningi kwezingxenye ezincane ze-elekthronikhi.

Imboni Yezimoto:Isetshenziselwa izingxenye ezingamelani nokushisa ezinjinini zezimoto, izinhlelo zikagesi, kanye ne-chassis, njenge-gaskets zekhanda lesilinda senjini, izindawo zokugcina amakhoyili okushiswa, ama-sensor brackets, kanye nezingxenye zesistimu yokubhuleka. Lezi zingxenye zidinga ukumelana nokushisa okuphezulu kwenjini isikhathi eside (120-180℃) kanye nemiphumela yokudlidliza. Izinhlanganisela zokubumba ze-phenolic ziyahlangabezana nalezi zidingo ngenxa yokumelana kwazo nokushisa okuphezulu, ukumelana nowoyela, kanye namandla omshini. Zilula futhi kunezinto zensimbi, zinegalelo ekunciphiseni isisindo kanye nokusebenza kahle kukaphethiloli ezimotweni. Izinhlanganisela zokubumba ezicindezelwe zifanele izingxenye eziqinile ezingamelani nokushisa ezizungeze injini, kuyilapho izinhlanganisela zokubumba ezijovwe zisetshenziselwa izingxenye zikagesi ezincane neziphakathi.

Izinto zikagesi zasekhaya:Ifanele izingxenye zesakhiwo nezisebenzayo ezingamelani nokushisa ezintweni zikagesi ezifana nezitofu zerayisi, ama-oven, ama-oven e-microwave, kanye nemishini yokuwasha, njengezisekelo zangaphakathi zebhodwe lesitofu serayisi, izinto zokufaka izinto zokushisa kuhhavini, izingxenye zokuvala umnyango we-oven ye-microwave, kanye nezimbozo zemoto yomshini wokuwasha. Izingxenye zikagesi zidinga ukumelana namazinga okushisa aphakathi kuya kwaphezulu (80-150℃) kanye nezindawo ezinomswakama ngesikhathi sokusetshenziswa kwansuku zonke.Ama-phenolic molding compoundszinikeza izinzuzo ezibalulekile ekumelaneni nokushisa okuphezulu, ukumelana nomswakama, kanye nezindleko eziphansi. Ama-compound molding compounds, ngenxa yokusebenza kahle kwawo okuphezulu kokukhiqiza, abe yisinqumo esiyinhloko embonini yezinto zikagesi zasekhaya.

Ezinye izinhlelo zokusebenza zifaka phakathi izindiza (njengezingxenye ezincane zokuvikela imishini yomoya), amadivayisi ezokwelapha (njengezingxenye zokubulala amagciwane ezinokushisa okuphezulu), kanye nama-valve ezimboni (njengezihlalo zokuvala ama-valve). Isibonelo, amathreyi okubulala amagciwane anokushisa okuphezulu kumadivayisi ezokwelapha adinga ukumelana nokuhlanza umusi ngomfutho ophezulu ongu-121°C, kanye nama-phenolic molding compounds angahlangabezana nezidingo zokumelana nokushisa kanye nokuhlanzeka; izihlalo zokuvala ama-valve ezimboni zidinga ukumelana nokugqwala kwemidiya kanye namazinga okushisa athile, okugqamisa ukuzivumelanisa kwazo nezimo eziningi.
