I-Bulk Phenolic Fiberglass Molding Compound
Isingeniso Somkhiqizo
I-Bulk phenolic glass fiber molding compound iyinhlanganisela yokubumba ye-thermosetting eyenziwe nge-phenolic resin njengento eyisisekelo, eqiniswe ngemicu yengilazi, futhi yenziwa ngokufaka, ukuxuba nezinye izinqubo. Ukwakheka kwayo kuvame ukuhlanganisa i-phenolic resin (i-binder), i-glass fibre (izinto eziqinisayo), isigcwalisi samaminerali nezinye izithasiselo (njenge-flame retardant, i-ejenti yokukhululwa kwesikhunta, njll.).
Izimpawu Zokusebenza
(1) Izakhiwo ezinhle kakhulu zemishini
Amandla okugoba aphezulu: eminye imikhiqizo ingafinyelela ku-790 MPa (yedlula kude izinga likazwelonke ≥ 450 MPa).
Ukumelana nomthelela: amandla omthelela angekho ≥ 45 kJ/m², afanele izingxenye ezingaphansi kwemithwalo eguquguqukayo.
Ukumelana nokushisa: Izinga lokushisa likaMartin elimelana nokushisa ≥ 280 ℃, ukuzinza okuhle kwe-dimensional emazingeni okushisa aphezulu, kulungele ukusetshenziswa kwemvelo okunokushisa okuphezulu.
(2) Izakhiwo zokuvikela ugesi
Ukumelana nobuso: ≥1×10¹² Ω, ukumelana nevolumu ≥1×10¹⁰ Ω-m, ukuze kuhlangatshezwane nezidingo eziphezulu zokwahlukanisa.
Ukumelana ne-Arc: eminye imikhiqizo inesikhathi sokumelana ne-arc ≥180 imizuzwana, ifanele izingxenye zikagesi ezinamandla aphezulu.
(3) Ukumelana nokugqwala kanye nokuncipha komlilo
Ukumelana nokugqwala: ukumelana nomswakama kanye nesikhutha, kulungele izindawo ezishisayo nezinomswakama noma ezonakalisayo ngamakhemikhali.
Ibanga elivimba amalangabi: eminye imikhiqizo isifinyelele ebangeni le-UL94 V0, engashi uma kuba nomlilo, intuthu ephansi futhi engenabo ubuthi.
(4) Ukucubungula ukuzivumelanisa nezimo
Indlela yokubumba: ukusekela ukubunjwa komjovo, ukubunjwa kokudlulisa, ukubunjwa kokucindezela nezinye izinqubo, ezifanele izingxenye zesakhiwo esiyinkimbinkimbi.
I-shrinkage ephansi: ukuncipha kokubumba ≤ 0.15%, ukunemba okuphezulu kokubumba, kunciphisa isidingo sokucubungula ngemuva.
Imingcele Yezobuchwepheshe
Okulandelayo amanye amapharamitha wezobuchwepheshe emikhiqizo ejwayelekile:
| Into | Inkomba |
| Ukuminyana (g/cm³) | 1.60~1.85 |
| Amandla okugoba (MPa) | ≥130~790 |
| Ukumelana Nobuso (Ω) | ≥1×10¹² |
| I-Dielectric loss factor (1MHz) | ≤0.03~0.04 |
| Ukumuncwa kwamanzi (mg) | ≤20 |
Izinhlelo zokusebenza
- Imboni ye-Electromechanical: Ukwenziwa kwezingxenye zokuvikela ezinamandla eziphakeme njengamagobolondo emoto, othintana naye, abagibeli, njll.
- Imboni yezimoto: isetshenziswa ezingxenyeni zenjini, izingxenye zesakhiwo somzimba, ukuthuthukisa ukumelana nokushisa nesisindo esincane.
- I-Aerospace: izingxenye zesakhiwo ezimelana nokushisa okuphezulu, njengezingxenye zamarokhethi.
- Imishini kagesi kanye nekagesi: izingxenye zokufakwa kwamandla kagesi aphezulu, shintsha izindlu, ukuze kuhlangatshezwane nezidingo ze-flame retardant kanye nokusebenza kukagesi.
Izinyathelo Zokucubungula Nokugcina
Inqubo yokucindezela: izinga lokushisa 150±5℃, ingcindezi 18-20Mpa, isikhathi 1~1.5 min/mm.
Isimo sesitoreji: Vikela ekukhanyeni nakumswakama, isikhathi sokugcina ≤ izinyanga ezingu-3, bhaka ku-90 ℃ imizuzu engu-2 ~ 4 ngemva komswakama.
