Isininzi Phenolic Fiberglass Molding Compound
Intshayelelo yeMveliso
Ubuninzi be-phenolic glass fiber molding compound yi-thermosetting molding compound eyenziwe nge-phenolic resin njengesiseko sezinto, zomelezwa ngeefiber zeglasi, kwaye zenziwe ngokufakelwa, ukuxuba kunye nezinye iinkqubo. Ukubunjwa kwayo ngokuqhelekileyo kubandakanya i-phenolic resin (i-binder), i-fiber yeglasi (izinto zokuqinisa), i-mineral filler kunye nezinye izongezo (ezifana ne-flame retardant, i-ejenti yokukhululwa kwe-mold, njl.).
Iimpawu zoMsebenzi
(1) Iipropati ezigqwesileyo zoomatshini
Amandla okugoba aphezulu: ezinye iimveliso zinokufikelela kwi-790 MPa (idlula kakhulu umgangatho wesizwe ≥ 450 MPa).
Ukuchasana nokuchaphazeleka: amandla empembelelo ephawulweyo ≥ 45 kJ/m², ilungele iindawo eziphantsi kwemithwalo eguqukayo.
Ukumelana nobushushu: Ubushushu obunganyangekiyo nguMartin ≥ 280 ℃, uzinzo oluhle lomgangatho kumaqondo obushushu aphezulu, alungele izicelo zokusingqongileyo ezinobushushu obuphezulu.
(2) Iimpawu zokugquma umbane
Ukumelana nomphezulu: ≥1×10¹² Ω, ukuxhathisa umthamo ≥1×10¹⁰ Ω-m, ukuhlangabezana neemfuno eziphezulu zokugquma.
Ukumelana ne-Arc: ezinye iimveliso zinexesha lokumelana ne-arc ≥180 imizuzwana, ifanelekile kumacandelo ombane aphezulu.
(3) Ukumelana nokubola kunye nokunqanda umlilo
Ukumelana nokukhula: ukumelana nokufuma kunye nokungunda, kulungele indawo eshushu kunye nefumileyo okanye enomhlwa ngokwekhemikhali.
Ibakala lokungatshanga mlilo: ezinye iimveliso zifikelele kwibakala le-UL94 V0, ezingatshiyo xa kukho umlilo, umsi ophantsi kwaye ungeyotyhefu.
(4) Ukulungelelanisa ukulungelelanisa
Indlela yokubumba: ukuxhasa ukubunjwa kwenaliti, ukubunjwa kokudluliselwa, ukubunjwa koxinzelelo kunye nezinye iinkqubo, ezifanelekileyo kumacandelo anzima.
I-shrinkage ephantsi: i-shrinkage yokubumba ≤ 0.15%, ukuchaneka okuphezulu kokubumba, ukunciphisa imfuno yokuthunyelwa kwe-post-processing.
Iiparamitha zobuGcisa
Ezi zilandelayo zezinye zeeparamitha zobugcisa zeemveliso eziqhelekileyo:
| Into | Isalathisi |
| Ubuninzi (g/cm³) | 1.60~1,85 |
| Amandla okugoba (MPa) | ≥130~790 |
| Ukuxhathisa uMbuso (Ω) | ≥1×10¹² |
| Ilahleko yeDielectric factor (1MHz) | ≤0.03~0.04 |
| Ukufunxa amanzi (mg) | ≤20 |
Usetyenziso
- Umzi-mveliso we-Electromechanical: Ukwenziwa kweendawo ezikhuselayo eziphezulu ezinje ngamaqokobhe emoto, abafowunelwa, abakhweli, njl.
- Umzi-mveliso weemoto: ezisetyenziswa kumalungu e-injini, amalungu esakhiwo somzimba, ukuphucula ukumelana nobushushu kunye nobunzima obulula.
- I-Aerospace: I-aerospace: iindawo zesakhiwo ezixhathisa ubushushu obuphezulu, njengamalungu e-rocket.
- Izixhobo zombane kunye nezixhobo zombane: iinxalenye ze-insulation high-voltage, ukutshintshwa kwezindlu, ukuhlangabezana neemfuno ze-flame retardant kunye nokusebenza kombane.
ImiGaqo yoMsebenzi kunye noGcino
Inkqubo yokucofa: iqondo lobushushu 150±5℃, uxinzelelo 18-20Mpa, ixesha 1 ~ 1.5 min/mm.
Imeko yokugcina: Khusela ukukhanya kunye nomswakama, ixesha lokugcina ≤ iinyanga ezi-3, bhaka kwi-90 ℃ kwi-2 ~ 4 imizuzu emva komswakama.
