I-Bulk Phenolic Fiberglass Molding Compound
Intshayelelo yeMveliso
I-compound ye-phenolic glass fiber molding compound yi-thermosetting molding compound eyenziwe nge-phenolic resin njengezinto ezisisiseko, iqiniswe nge-glass fibers, kwaye yenziwe ngokufaka i-impregnation, ukuxuba kunye nezinye iinkqubo. Ukwakheka kwayo kudla ngokuquka i-phenolic resin (i-binder), i-glass fiber (izinto zokuqinisa), i-mineral filler kunye nezinye izongezo (ezifana ne-flame retardant, i-mold release agent, njl.njl.).
Iimpawu zokusebenza
(1) Iipropati ezibalaseleyo zoomatshini
Amandla aphezulu okugoba: ezinye iimveliso zinokufikelela kwi-790 MPa (zidlula kakhulu umgangatho wesizwe ≥ 450 MPa).
Ukumelana neempembelelo: amandla empembelelo aqhekekileyo ≥ 45 kJ/m², afanelekile kwiindawo ezithwalwa yimithwalo enamandla.
Ukumelana nobushushu: Ubushushu obungamelani nobushushu bukaMartin ≥ 280 ℃, uzinzo oluhle olunemilinganiselo kumaqondo obushushu aphezulu, olufanele ukusetyenziswa kokusingqongileyo kumaqondo obushushu aphezulu.
(2) Iimpawu zokukhusela umbane
Ukumelana nomphezulu: ≥1×10¹² Ω, ukumelana nomthamo ≥1×10¹⁰ Ω-m, ukuhlangabezana neemfuno eziphezulu zokukhusela ubushushu.
Ukumelana ne-arc: ezinye iimveliso zinexesha lokumelana ne-arc ≥ imizuzwana eli-180, zilungele izixhobo zombane ezine-voltage ephezulu.
(3) Ukumelana nokugqwala kunye nokungavuthi komlilo
Ukumelana nokugqwala: ukumelana nokufuma kunye nokungunda, kufanelekile kwiindawo ezishushu nezifumileyo okanye ezinobungozi beekhemikhali.
Umgangatho othintela ilangatye: ezinye iimveliso zifikelele kumgangatho we-UL94 V0, azitshi xa kukho umlilo, umsi omncinci kwaye azinatyhefu.
(4) Ukuzivumelanisa nezimo zokucubungula
Indlela yokubumba: ukuxhasa ukubumba ngenaliti, ukudlulisa ukubumba, ukubumba ngokucinezela kunye nezinye iinkqubo, ezifanelekileyo kwiindawo ezintsonkothileyo zesakhiwo.
Ukuncipha okuphantsi: ukuncipha kokubumba ≤ 0.15%, ukuchaneka okuphezulu kokubumba, okunciphisa imfuneko yokucubungula emva kokubumba.
Iiparameters zobugcisa
Ezi zilandelayo zezinye zeendlela zobugcisa zeemveliso eziqhelekileyo:
| Into | Isalathisi |
| Uxinano (g/cm³) | 1.60~1.85 |
| Amandla okugoba (MPa) | ≥130~790 |
| Ukumelana nomphezulu (Ω) | ≥1×10¹² |
| I-Dielectric loss factor (1MHz) | ≤0.03~0.04 |
| Ukufunxwa kwamanzi (mg) | ≤20 |
Izicelo
- Ishishini le-electromechanical: Ukuveliswa kwezixhobo zokukhusela ezisebenza ngamandla aphezulu ezifana nee-motor shells, ii-contactors, ii-commutators, njl.
- Ishishini leemoto: lisetyenziswa kwiindawo zenjini, kwiindawo zesakhiwo somzimba, ukuphucula ukumelana nobushushu kunye nobunzima obuphantsi.
- I-Aerospace: iindawo zesakhiwo ezimelana nobushushu obuphezulu, ezifana neendawo zerokethi.
- Izixhobo ze-elektroniki nezombane: iindawo zokukhusela umbane ezine-voltage ephezulu, izindlu zokutshintsha, ukuhlangabezana neemfuno ze-flame retardant kunye nokusebenza kombane.
Amanyathelo okukhusela nokugcina izinto
Inkqubo yokucinezela: ubushushu obuyi-150±5℃, uxinzelelo oluyi-18-20Mpa, ixesha eliyi-1~1.5 min/mm.
Imeko yokugcina: Khusela ekukhanyeni nasekufumeni, ixesha lokugcina ≤ iinyanga ezi-3, bhaka kwi-90℃ imizuzu emi-2-4 emva kokufuma.
