izindaba

I-Phenolic molding compounds yizinto zokubumba ze-thermosetting ezenziwe ngokuxuba, ukuxova, kanye ne-granulating phenolic resin njenge-matrix enezigcwalisi (ezifana nofulawa wokhuni, i-glass fiber, kanye ne-mineral powder), ama-ejenti okwelapha, okokugcoba, nezinye izithasiselo. Izinzuzo zabo eziyinhloko zisezingeni eliphezulu kakhulu lokumelana nezinga lokushisa eliphezulu (izinga lokushisa elisebenza isikhathi eside elifika ku-150-200℃), izakhiwo zokufaka izinto (ukumelana nevolumu ephezulu, ukulahlekelwa okuphansi kwe-dielectric), amandla emishini, nokuzinza kwe-dimensional. Ziyakwazi futhi ukumelana nokugqwala kwamakhemikhali, zinezindleko ezilawulekayo, futhi zigcina ukusebenza okuzinzile ngisho nangaphansi kwezinga lokushisa eliphezulu, amandla kagesi aphezulu, noma izindawo ezinomswakama.

Izinhlobo zePhenolic Molding Compounds 

I-Compress Molding Compounds:Lezi zidinga ukubunjwa kokucindezela. Impahla ifakwa esikhunjeni bese yelapheka ngaphansi kwezinga lokushisa eliphezulu nengcindezi (imvamisa i-150-180 ℃ kanye ne-10-50MPa). Afanele ukukhiqiza umumo oyinkimbinkimbi, izidingo zokunemba kobukhulu obuphakeme, noma izingxenye ezinkulu, ezinodonga oluwugqinsi, njengezisekelo zokuvikela impahla kagesi nezinto ezikwazi ukumelana nokushisa ezizungeze izinjini zezimoto. Ngokuhlakazeka kwe-filler efanayo, imikhiqizo ibonisa amandla aphakeme wemishini kanye nokumelana nezinga lokushisa eliphezulu, okuyenza isetshenziswe kabanzi ezingxenyeni zezimboni ezimaphakathi kuya phezulu kanye nohlobo lomkhiqizo ojwayelekile ojwayelekile.

Izinhlanganisela zokubumba umjovo:Ifanele izinqubo zokubumba umjovo, lezi zinto ezisetshenziswayo zinokugeleza okuhle futhi zingagcwaliswa ngokushesha futhi zelashwe emshinini wokubumba umjovo, okuholela ekusebenzeni kahle kokukhiqiza okuphezulu kanye nokuzenzakalelayo. Afanele ukukhiqizwa ngobuningi bezingxenye ezincane kuya kosayizi omaphakathi, ezinesakhiwo esivamile, njengamapaneli okushintsha izinto zasendlini, izixhumi ze-elekthronikhi zezimoto, nezingxenye ezincane zokufakwa kukagesi. Ngokuthandwa kwezinqubo zokubumba umjovo kanye nokwenza kahle kokugeleza kwezinto ezibonakalayo, isabelo semakethe sale mikhiqizo sikhula kancane kancane, ikakhulukazi njengoba sihlangabezana nezidingo ezinkulu zokukhiqiza zemikhiqizo yezimboni zabathengi.

Izindawo Zokusebenza zePhenolic Molding Compounds

Izinto zikagesi/zama-elekthronikhi:Lesi yisimo sohlelo lokusebenza esiwumongo, esimboza izingxenye zokufakelwa kanye nezingxenye zesakhiwo zemishini efana nezinjini, ama-transformer, ama-circuit breaker, nama-relay, anjengama-motor commutators, amafreyimu okufaka ama-transformer, namatheminali ama-circuit breaker. I-insulation ephezulu kanye nokumelana nokushisa okuphezulu kwe-phenolic molding compounds kuqinisekisa ukusebenza okuphephile kwemishini kagesi ngaphansi kwezimo eziphezulu ze-voltage kanye nezimo ezishisa kakhulu, ukuvimbela izifunda ezimfushane ezibangelwa ukwehluleka kwe-insulation. Izinhlanganisela zokubumba zokucindezelwa zisetshenziswa kakhulu ezingxenyeni ezibucayi zokufaka umjovo, kanti izinhlanganisela zokubumba umjovo zilungele ukukhiqizwa ngobuningi bezinto ezincane ze-elekthronikhi.

Imboni Yezimoto:Isetshenziselwa izingxenye ezimelana nokushisa ezinjinini zezimoto, amasistimu kagesi, kanye ne-chassis, njengama-gaskets enjini ye-cylinder head, izindlu zamakhoyili okushisa, abakaki bezinzwa, nezingxenye zesistimu yokubhuleka. Lezi zingxenye zidinga ukumelana namazinga okushisa enjini esikhathi eside (120-180℃) nomthelela wokudlidliza. Ama-phenolic molding compounds ahlangabezana nalezi zidingo ngenxa yokumelana kwawo nezinga lokushisa eliphezulu, ukumelana nowoyela, namandla emishini. Alula futhi kunezinsimbi, okunomthelela ekwehliseni isisindo kanye nokusebenza kahle kukaphethiloli ezimotweni. Izinhlanganisela zokubumba zokuminyanisa zifanele izingxenye eziwumgogodla ezimelana nokushisa ezizungeze injini, kuyilapho izinhlanganisela zokubumba umjovo zisetshenziselwa izingxenye zikagesi ezincane neziphakathi nendawo.

Imishini Yasendlini:Ifanele izakhiwo ezikwazi ukumelana nokushisa nezinto ezisebenzayo kuzinto ezisetshenziswayo njengezipheki zelayisi, ohhavini, ohhavini bemicrowave, nemishini yokuwasha, njengezisekelo zebhodwe langaphakathi le-rice cooker, izinto zokubeka ukushisa kuhhavini, izingxenye zokuvala iminyango ye-microwave oven, kanye namakhava okuphela kwemishini yokuwasha. Izingxenye zikagesi zidinga ukumelana nezinga lokushisa eliphakathi nendawo ukuya phezulu (80-150℃) kanye nezindawo ezinomswakama ngesikhathi sokusetshenziswa kwansuku zonke.Ama-phenolic molding compoundszinikeza izinzuzo ezibalulekile ekumelaneni nezinga lokushisa eliphezulu, ukumelana nomswakama, kanye nezindleko eziphansi. Izinhlanganisela zokubumba umjovo, ngenxa yokusebenza kahle kwazo okuphezulu, seziphenduke into esemqoka embonini yemishini yasendlini.

Ezinye izinhlelo zokusebenza zifaka i-aerospace (njengezinto ezincane zokuvalela izinto ezisetshenziswa emoyeni), izinto zokwelapha (njengezingxenye ezivala izinga lokushisa eliphezulu), namavalvu ezimboni (njengezihlalo zokuvala ama-valve). Isibonelo, amathreyi okukhipha inzalo okushisa aphezulu kumishini yezokwelapha adinga ukumelana no-121°C ukuvalwa komshini wokucindezela okuphezulu, kanye nezinhlanganisela zokubumba ze-phenolic zingahlangabezana nezidingo zokumelana nezinga lokushisa kanye nenhlanzeko; izihlalo zokuvala ama-valve ezimbonini kumele zimelane nokugqwala kwemidiya kanye namazinga okushisa athile, okugqamisa ukuzivumelanisa kwazo nezimo eziningi.
