Bulk Phenolic Fiberglass Molding Compound
Product Sumo
Bulk phenolic girazi fiber molding compound ndeye thermosetting molding compound yakagadzirwa ne phenolic resin sechinhu chekutanga, yakasimbiswa negirazi fiber, uye inogadzirwa nekupinza, kusanganisa uye mamwe maitiro. Kuumbwa kwayo kunowanzo sanganisira phenolic resin (binder), girazi fiber (inosimbisa zvinhu), mineral filler uye zvimwe zvinowedzera (senge flame retardant, mold release agent, etc.).
Performance Characteristics
(1) Yakanakisa michina zvinhu
Simba rekukotama rakakwirira: zvimwe zvigadzirwa zvinogona kusvika 790 MPa (kure kupfuura chiyero chenyika ≥ 450 MPa).
Impact kuramba: notched impact simba ≥ 45 kJ/m², inokodzera zvikamu zviri pasi pemitoro ine simba.
Kupisa kupikisa: Martin kupisa-kupikisa tembiricha ≥ 280 ℃, yakanaka dimensional kugadzikana pakupisa kwepamusoro, yakakodzera kune yakakwirira-tembiricha yezvakatipoteredza zvikumbiro.
(2) Magetsi ekudzivirira zvinhu
Surface resistivity: ≥1 × 10¹² Ω, vhoriyamu resistivity ≥1 × 10¹⁰ Ω-m, kuzadzisa izvo zvakakwirira zvekudzivirira zvinodiwa.
Arc resistance: zvimwe zvigadzirwa zvine arc resistance time ≥180 seconds, inokodzera high-voltage magetsi zvikamu.
(3) Corrosion resistance uye kunonoka kwemurazvo
Corrosion resistance: hunyoro uye mildew inodzivirira, inokodzera kupisa uye kunyorova kana kukonzeresa makemikari nharaunda.
Giredhi rinodzoreredza moto: zvimwe zvigadzirwa zvasvika UL94 V0 giredhi, zvisingabatike kana moto, utsi hushoma uye husina chepfu.
(4) Kugadzirisa kuchinjika
Molding nzira: kutsigira jekiseni kuumba, kutamisa kuumba, compression molding uye mamwe maitiro, akakodzera kune yakaoma zvimiro zvikamu.
Low shrinkage: kuumba shrinkage ≤ 0.15%, high molding precision, kuderedza kudiwa kwemashure ekugadzirisa.
Technical Parameters
Zvinotevera ndezvimwe zvetekinoroji paramita yezvakajairwa zvigadzirwa:
| Item | Indicator |
| Density (g/cm³) | 1.60~1.85 |
| Kubhenda simba (MPa) | ≥130~790 |
| Kuramba Kwepamusoro (Ω) | ≥1×10¹² |
| Dielectric kurasikirwa chinhu (1MHz) | ≤0.03~0.04 |
| Kutorwa kwemvura (mg) | ≤20 |
Applications
- Indasitiri yeElectromechanical: Kugadzirwa kweakakwira-simba rekudzivirira zvikamu zvakaita semagomba emota, macontactor, macommutators, nezvimwe.
- Indasitiri yemotokari: inoshandiswa muzvikamu zveinjini, zvikamu zvechimiro chemuviri, kugadzirisa kupisa kwekudzivirira uye huremu huremu.
- Aerospace: yakakwirira tembiricha inodzivirira zvimiro zvikamu, senge roketi zvikamu.
- Zvishandiso zvemagetsi nemagetsi: yakakwira-voltage insulation zvikamu, chinja imba, kusangana nezvinodiwa zvemurazvo wemoto uye kushanda kwemagetsi.
Kugadzirisa uye Kuchengetedza Kuchengetedza
Kudzvanya muitiro: tembiricha 150 ± 5 ℃, kumanikidzwa 18-20Mpa, nguva 1 ~ 1.5 min/mm.
Kuchengetedza mamiriro: Chengetedza kubva kuchiedza uye unyoro, nguva yekuchengetedza ≤ 3 mwedzi, kubika pa 90 ℃ kwe2 ~ 4 maminetsi mushure mekunyorova.
