Lisosa tse Tloaelehileng tsa ho hloleha ho Fasteners le Mokhoa oa ho li Thibela
2025-06-19
Li-fasteners li bapala karolo ea bohlokoa ho netefatsa boits'oaro ba sebopeho ho pholletsa le liindasteri, ho tloha sebakeng sa lifofane ho isa ho tsa kaho. Leha ho le joalo, khetho e fosahetseng, ho kenya, kapa maemo a tikoloho ho ka lebisa ho hloleheng pele ho nako, ho bakang nako e theko e boima le likotsi tsa polokeho. Sengoliloeng sena se hlahloba lisosa tse atileng haholo tsa ho hloleha ho fastening ebile e fana ka mehato ea thibelo ho matlafatsa botshepehi.
Corrosion: 'Molai ea Khutsitseng
Corrosion ke e 'ngoe ea lisosa tse ka sehloohong tsa ho senyeha ha sekhahla, haholo-holo libakeng tse thata joalo ka ts'ebeliso ea leoatle, lik'hemik'hale le kantle ho naha.
| Mofuta oa Corrosion | Lisosa | Mekhoa ea Thibelo |
|---|---|---|
| Galvanic Corrosion | Litšepe tse sa ts'oaneng tse hokahaneng (mohlala, boutu ea tšepe karolong ea aluminium) | Sebelisa litšepe tse lumellanang kapa li-washer tse sireletsang metsi |
| Crevice Corrosion | Mongobo o qabeletsoe ka har'a likheo (mohlala, tlas'a lihlooho tsa bolt) | Sebelisa li-sealants, sebelisa liphahlo tse thibelang ho bola |
| Stress Corrosion Cracking (SCC) | Khatello ea maikutlo + tikoloho e senyang | Sebelisa li-alloys tse phahameng tsa nickel (mohlala, Inconel), fokotsa khatello ea kelello e sebelisoang |
tharollo: khetha litšepe tse se nang tšepe, titanium, kapa li-fasteners tsa nickel alloy bakeng sa libaka tse senyang.
Ho Hlōleha Mokhathala: Ha Khatello ea Khatello e Phethahalang e Phetha Bohloko
Li-fasteners tse kenngoeng ke cyclic loading (mohlala, ka mechine, likoloi, kapa lifofane) li ka hlōleha ka lebaka la mokhathala.
| Matšoao a ho Hlōleha Mokhathala | Maano a Thibelo |
|---|---|
| Mapetso haufi le metso ea khoele | tshebediso likhoele tse phuthotsoeng (eseng ho khaola) bakeng sa bophelo bo botle ba mokhathala |
| Ho robeha ha khatello ea maikutlo | Etsa kopo jarollo e nepahetseng ho fokotsa khatello ea kelello ea cyclic |
| Ho hlephisa ho tsoelang pele | tshebediso ho notlela mekhoa (mohlala, liwasher tsa Nord-Lock) |
tharollo: khetha li-alloys tse matla haholo, tse hananang le mokhathala (mohlala, titanium ea Kereiti ea 5, Inconel 718).
Ho Feta-Tlhokotsa le ho Hlokoloha ka Tlase
Ho tiisa ka tsela e fosahetseng ho ka lebisa ho ho hlobola khoele, ho otlolla bolt, kapa ho hloleha hoa manonyeletso.
| Hlahisa | le phello | thibelo ea |
|---|---|---|
| Ho Feta-Tlosa | Bolt elongation, tšenyo ea khoele | Sebelisa a wrench ea torque e lekantsoeng, latela litlhaloso tsa moetsi |
| Tlas'a-Tsamaiso | Ho thothomela ho hlephileng, karohano ea manonyeletso | Etsa kopo jarollo e nepahetseng, sebelisa metsoako e koalang khoele |
tharollo: Follow lichate tsa torque e thehilweng hodima thepa le setlolo.
Phello ea Haedrojene (HE)
Ho ameha haholo ka li-fasteners tsa tšepe tse matla, hore liathomo tsa haedrojene li fokolisa tšepe.
| Lisosa | thibelo ea |
|---|---|
| Electroplating (mohlala, liboutu tse koahetsoeng ka zinki) | Bake fasteners ka mor'a ho plating ho tlosa hydrogen |
| Ho pepesetsoa libakeng tse nang le asiti | tshebediso litlolo tse se nang motlakase (mohlala, Dacromet) |
tharollo: Bakeng sa lisebelisoa tsa bohlokoa, sebelisa litlolo tse se nang haedrojene kapa switjha ho li-alloys tsa titanium/nickel.
Khetho e Fosahetseng ea Lintho
Ho sebelisa sekontiri se fosahetseng bakeng sa ts'ebeliso ho ka lebisa ho hloleheng pele ho nako.
| Boemo bo sa lumellaneng | E 'ngoe e khothalelitsoeng |
|---|---|
| Tšepe ea carbon ka metsing a letsoai | Tšepe e se nang tšepe (316) kapa titanium |
| Aluminium ka mocheso o phahameng | Nickel alloy (Inconel 600) |
| Plastiki tlas'a mojaro | Li-fasteners tsa alloy tse matla haholo |
tharollo: bale lichate tsa ho lumellana ha lintho pele ho khetho.
Qetello: Mokhoa oa ho Etsa bonnete ba ho Tšepahala ho Fastener
Ho eketsa nako ea bophelo ea fastener:
- Khetha boitsebiso bo nepahetseng (li-alloys tse hanang ho bola bakeng sa tikoloho e thata)
- Kenya torque e nepahetseng (sebelisa lisebelisoa tse lekantsoeng, latela lintlha)
- Sebelisa mekhoa e thibelang ho lokoloha (lihlapa tsa linotlolo, likhomaretsi)
- Hlahloba kamehla (hlahloba hore na ha ho kutu, ho phatloha ha mokhathala)
At Theknoloji ea TSM, rea fana li-fasteners tse sebetsang hantle in titanium, alloys nickel, le tšepe e sa hloekang, ho etsa bonnete ba ho tšoarella maemong a boima ka ho fetisisa.
