Phenolic Fiberglass Molding Tape
Kuumbwa Kwezvinhu Uye Kugadzirira
Ribhoni phenolic glass fiber molding compounds inoumbwa nekushandisa phenolic resin sebinder, kuisa alkali-isina girazi fibers (iyo inogona kunge yakareba kana chaotically oriented), uye ipapo kuomesa uye kuumba kuita ribhoni prepreg. Mamwe ma modifiers anogona kuwedzerwa panguva yekugadzirira kukwidziridza processability kana chaiyo physicochemical properties.
Kusimbisa: Girazi fibers inopa yakakwirira mechanical simba uye kukanganisa kwekudzivirira;
Resin matrix: phenolic resins inopa zvinhu zvinopisa kupisa kusagadzikana uye magetsi ekudzivirira zvinhu;
Zviwedzere: zvinogona kusanganisira zvinodzosa moto, mafuta ekuzora, nezvimwe, zvichienderana nezvinodiwa zvekushandisa.
Performance Characteristics
| Performance zviratidzo | Parameter range/ characteristics |
| Mechanical properties | Flexural simba ≥ 130-790 MPa, simba rekuita ≥ 45-239 kJ/m², tensile simba ≥ 80-150 MPa |
| Kudzivisa kupisa | Martin kupisa ≥ 280 ℃, yakakwirira tembiricha kuita kugadzikana |
| Electrical properties | pamusoro pekudzivirira ≥ 1 × 10¹² Ω, vhoriyamu kuramba ≥ 1 × 10¹⁰ Ω-m, simba remagetsi ≥ 13-17.8 MV/m |
| Kutorwa kwemvura | ≤20 mg (kunyura kwemvura yakaderera, yakakodzera nzvimbo dzine hunyoro) |
| Shrinkage | ≤0.15% (yakakwirira dimensional kugadzikana) |
| Density | 1.60-1.85 g/cm³ (yakareruka uye yakasimba simba) |
Processing Technology
1. Kutsikirira mamiriro:
- Tembiricha: 150±5°C
- Kudzvinyirira: 350±50kg/cm²
- Nguva: 1-1.5 maminitsi / mm ukobvu
2. Nzira yekugadzira: lamination, compression molding, kana pasi-pressure molding, yakakodzera kune yakaoma maumbirwo emucheka kana mashizha-akafanana nezvikamu zvemaitiro.
Minda Yekushandisa
- Kuvharirwa kwemagetsi: rectifiers, motor insulators, etc. Kunyanya yakakodzera kune inopisa uye ine hunyoro nharaunda;
- Mechanical components: yakakwirira-simba zvimiro zvikamu (eg kutakura dzimba, magiya), motokari injini zvikamu;
- Aerospace: lightweight, high-temperature resistant parts (somuenzaniso, mabhuraketi emukati mendege);
- Munda wekuvaka: inodzivirira-inodzivirira pombi inotsigira, matemplate ekuvaka, nezvimwe.
Kuchengetedza uye Kuchengetedza
- Mamiriro ekuchengetedza: Inofanirwa kuiswa munzvimbo inotonhorera uye yakaoma kudzivirira kunyura kwemwando kana kudzikira kwekupisa; kana ikabatwa nehunyoro, inofanira kubikwa pa90±5℃ kwemaminitsi 2-4 isati yashandiswa;
- Hupenyu hwesherufu: kuti ishandiswe mukati memwedzi mitatu kubva pazuva rekugadzirwa, kuita kunoda kuongororwazve mushure mekupera kwezuva;
- Rambidza kudzvinyirira kunorema: kudzivirira kukanganisa kune fiber chimiro.
Muenzaniso wechigadzirwa chigadzirwa
FX-501: Density 1.60-1.85 g/cm³, Flexural simba ≥130 MPa, Simba remagetsi ≥14 MV/m;
4330-1 (yakashata nzira): yakakwirira-simba inodzivirira yezvimiro zvikamu zvenzvimbo dzine hunyoro, kukotama simba ≥60 MPa.
