Inhlanganisela Yokubumba Ye-Fiberglass Eningi Ye-Phenolic
Isingeniso Somkhiqizo
I-compound ye-fiber yengilazi ye-phenolic eningi iyi-compound yokubumba ye-thermosetting eyenziwe nge-resin ye-phenolic njengezinto eziyisisekelo, iqiniswe ngemicu yengilazi, futhi yenziwe ngokufaka, ukuxuba nezinye izinqubo. Ukwakheka kwayo kuvame ukufaka i-resin ye-phenolic (i-binder), i-fiber yengilazi (izinto eziqinisayo), i-mineral filler nezinye izithasiselo (njenge-flame retardant, i-mold release agent, njll.).
Izici Zokusebenza
(1) Izakhiwo ezinhle kakhulu zemishini
Amandla aphezulu okugoba: eminye imikhiqizo ingafinyelela ku-790 MPa (edlula kakhulu izinga likazwelonke ≥ 450 MPa).
Ukumelana nomthelela: amandla omthelela aqhekekile ≥ 45 kJ/m², afanele izingxenye ezithwala imithwalo enamandla.
Ukumelana nokushisa: Izinga lokushisa likaMartin elimelana nokushisa ≥ 280 ℃, ukuzinza okuhle kobukhulu emazingeni okushisa aphezulu, okulungele ukusetshenziswa kwezemvelo ezishisa kakhulu.
(2) Izakhiwo zokuvikela ugesi
Ukumelana nomphezulu: ≥1×10¹² Ω, ukumelana nomthamo ≥1×10¹⁰ Ω-m, ukuze kuhlangatshezwane nezidingo zokuvikela eziphezulu.
Ukumelana ne-arc: eminye imikhiqizo inesikhathi sokumelana ne-arc ≥ imizuzwana engu-180, efanelekile izingxenye zikagesi ezinamandla aphezulu.
(3) Ukumelana nokugqwala kanye nokuphelelwa yilangatye
Ukumelana nokugqwala: ukumelana nomswakama kanye nesikhunta, kufanelekile ezindaweni ezishisayo nezinomswakama noma ezingcolisayo ngamakhemikhali.
Izinga elivimbela ilangabi: eminye imikhiqizo ifinyelele izinga le-UL94 V0, ayishisi uma kwenzeka umlilo, intuthu encane futhi ayinabo ubuthi.
(4) Ukuzivumelanisa nezimo kokucubungula
Indlela yokubumba: ukusekela ukubumba ngomjovo, ukubumba kokudlulisa, ukubumba kokucindezela nezinye izinqubo, ezifanele izingxenye zesakhiwo eziyinkimbinkimbi.
Ukuncipha okuphansi: ukuncipha kokubumba ≤ 0.15%, ukunemba okuphezulu kokubumba, kunciphisa isidingo sokucubungula ngemuva.
Amapharamitha Obuchwepheshe
Okulandelayo ezinye zezimiso zobuchwepheshe zemikhiqizo ejwayelekile:
| Into | Isikhombisi |
| Ubuningi (g/cm³) | 1.60~1.85 |
| Amandla okugoba (i-MPa) | ≥130~790 |
| Ukumelana Nomphezulu (Ω) | ≥1×10¹² |
| Isici sokulahlekelwa yi-dielectric (1MHz) | ≤0.03~0.04 |
| Ukumuncwa kwamanzi (mg) | ≤20 |
Izicelo
- Imboni ye-electromechanical: Ukwenziwa kwezingxenye zokuvikela ezinamandla aphezulu njengezigobolondo zemoto, ama-contactor, ama-commutator, njll.
- Imboni yezimoto: isetshenziswa ezingxenyeni zenjini, izingxenye zesakhiwo somzimba, ukuthuthukisa ukumelana nokushisa kanye nesisindo esincane.
- Izindiza: izingxenye zesakhiwo ezingamelana nokushisa okuphezulu, njengezingxenye zerokhethi.
- Izinto zikagesi neze-elekthronikhi: izingxenye zokushisa ezisebenzisa amandla aphezulu, izindlu zokushintsha, ukuze kuhlangatshezwane nezidingo zokulawula ilangabi nokusebenza kukagesi.
Izinyathelo Zokuqapha Nokucubungula
Inqubo yokucindezela: izinga lokushisa 150±5℃, ingcindezi 18-20Mpa, isikhathi 1~1.5 min/mm.
Isimo sokugcina: Vikela ekukhanyeni nasemswakama, isikhathi sokugcina ≤ izinyanga ezi-3, bhaka ku-90℃ imizuzu emi-2-4 ngemuva komswakama.
