Phenolic Fiberglass Molding Tape
Kupanga Zinthu Ndi Kukonzekera
Riboni phenolic galasi CHIKWANGWANI akamaumba mankhwala amapangidwa pogwiritsa ntchito phenolic utomoni monga binder, impregnating alkali wopanda galasi ulusi (omwe angakhale yaitali kapena chaotically oriented), ndiyeno kuyanika ndi akamaumba kupanga riboni prepreg. Zosintha zina zitha kuwonjezeredwa pokonzekera kukhathamiritsa kusinthika kapena ma physicochemical properties.
Kulimbitsa: Zingwe zamagalasi zimapereka mphamvu zamakina apamwamba komanso kukana kwamphamvu;
Utomoni masanjidwewo: utomoni phenolic kupereka zinthu kutentha dzimbiri kukana ndi magetsi kutchinjiriza katundu;
Zowonjezera: zitha kuphatikiza zoletsa moto, zothira mafuta, ndi zina zambiri, kutengera zomwe mukufuna.
Makhalidwe Antchito
| Zizindikiro zamachitidwe | Mtundu wa parameter/makhalidwe |
| Zimango katundu | Flexural mphamvu ≥ 130-790 MPa, mphamvu yamphamvu ≥ 45-239 kJ/m², kulimba kwamphamvu ≥ 80-150 MPa |
| Kukana kutentha | Martin kutentha ≥ 280 ℃, mkulu kutentha ntchito bata |
| Mphamvu zamagetsi | pamwamba resistivity ≥ 1 × 10¹² Ω, resistivity voliyumu ≥ 1 × 10¹⁰ Ω-m, mphamvu yamagetsi ≥ 13-17.8 MV/m |
| Kuyamwa madzi | ≤20 mg (mayamwidwe amadzi otsika, oyenera malo achinyezi) |
| Kuchepa | ≤0.15% (kukhazikika kwapamwamba) |
| Kuchulukana | 1.60-1.85 g/cm³ (wopepuka komanso wamphamvu kwambiri) |
Processing Technology
1. Kukanikizira:
- Kutentha: 150±5°C
- Kuthamanga: 350±50kg/cm²
- Nthawi: 1-1.5 mphindi / mm makulidwe
2. Njira yopangira: lamination, compression molding, kapena low-pressure forming, yoyenera mawonekedwe ovuta a strip kapena pepala-ngati structural parts.
Minda ya Ntchito
- Kutchinjiriza magetsi: rectifiers, motor insulators, etc. Makamaka oyenera malo otentha ndi chinyezi;
- Zigawo zamakina: zida zamakina amphamvu kwambiri (monga nyumba zokhala, magiya), zida zama injini zamagalimoto;
- Zamlengalenga: zopepuka, zolimbana ndi kutentha kwambiri (monga mabulaketi amkati mwa ndege);
- Zomangamanga: zothandizira mapaipi osagwirizana ndi dzimbiri, ma tempulo omanga, ndi zina.
Kusungirako ndi Kusamala
- Kusungirako: Iyenera kuyikidwa pamalo ozizira ndi owuma kuti asatengeke ndi chinyezi kapena kuwonongeka kwa kutentha; ngati imakhudzidwa ndi chinyezi, iyenera kuphikidwa pa 90 ± 5 ℃ kwa mphindi 2-4 musanagwiritse ntchito;
- Nthawi ya alumali: kuti igwiritsidwe ntchito mkati mwa miyezi itatu kuyambira tsiku lopangidwa, ntchitoyo iyenera kuyesedwanso pambuyo pa tsiku lotha ntchito;
- Letsani kupsinjika kwakukulu: kupewa kuwonongeka kwa kapangidwe ka fiber.
Chitsanzo cha mankhwala chitsanzo
FX-501: Kachulukidwe 1.60-1.85 g/cm³, Flexural mphamvu ≥130 MPa, Mphamvu yamagetsi ≥14 MV/m;
4330-1 (mayendedwe osokonekera): zida zomangira zolimba zolimba kwambiri m'malo achinyezi, mphamvu yopindika ≥60 MPa.
