Nylon screw ni a prat hpe gara lam ni gaw hkra machyi shangun ai kun?
Nylon screw ni a service life gaw masat da ai manu n re ai sha lawu na ahkyak ai lam ni a majaw dawdan da ai:
1. Arung arai amyu: PA6 (nylon 6) hte PA66 (nylon 66) ni hpe grau nna lang ai. PA66 gaw nbung katsi ai hpe hkam sharang lu ai atsam hte n-gun grau ja ai, shi a magam bungli prat gaw PA6 hta 20%-30% grau galu ai (Shawnglam: Plastics Hpaga Hpung, USA).
2. grup yin masa lam ni:
- Katsi ai: 80℃jan galu ai katsi ai gaw asak kaba wa ai hpe lawan shangun nna, bungli galaw ai aten hpe 50% jan kadun shangun ai (Engineering Plastics jai lang ai laika buk hpe yu u).
- Humidity: Humidity makau grup yin hta hka hpe hkap la nna jat wa ai majaw, jak rung a atsam hpe shayawm kau ya lu ai.
3. Hpaji n-gun: Dynamic n-gun (vibration zawn re ai) npu hta, magam bungli prat gaw n-gun n-gun n-nga ai n-gun hta na htam masum hta na htam mi sha rai nga ai (Germany mungdan na Fraunhofer Institute kaw na chyam dinglik ai jahpan).
Magam bungli prat gaw hpa rai kun?
Hpaga lam hte seng ai jahpan hku nga yang (Npawt nhpang: Borouge Plastics Hpaji Masa Shiga):
- Kaja ai makau grup yin (nta kata na katsi ai, katsi ai masa, n shamu n shamawt ai n-gun): 5-10 ning.
- N hkru n kaja ai grup yin (katsi ai shara, chemical n-gun n rawng ai): 1-3 ning.
Laksan mabyin: Mawdaw engine rung ni hta nga ai nylon screw ni gaw nbung katsi ai hte sau n san seng ai majaw, 2 ning tup galai shai ra ai (Toyota Technical Bulletin TMC-2022).
Nylon screw ni a prat hpe gara hku galu shangun na kun?
1. Arung arai ni hpe grau kaja hkra galaw ai: Glass-fiber-n-gun ja ai nylon hpe ra sharawng ai, dai gaw asak hpe 40% jat ya lu ai.
2. Makawp maga ladat ni:
- Hka n shang hkra galaw ai shingnip (polytetrafluoroethylene zawn re ai) hpe ntsa kaw bang da u.
- N-gun ja ai acid hte alkali ni hte matut mahkai ai lam hpe koi ga.
3. Galoi mung jep yu ra ai: Shata 6 shagu n-gun n rawng ai (sh) n-gun n rawng ai hpe jep yu nna, alawan galai kau ra ai.
