Thempereichara e Phahameng, e Thibela ho Corrosion, Li-Gears tsa PEEK tsa Precision tse Phahameng
Tlhaloso ea Sehlahisoa
Li-gear tsa rona tsa PEEK li etsoa ka theknoloji ea morao-rao e netefatsang boenjiniere bo nepahetseng le boleng bo tsitsitseng. Motsoako o ikhethileng oa lisebelisoa tsa PEEK le mekhoa e tsoetseng pele ea tlhahiso e fella ka likere tse nang le khanyetso e ntle ea ho roala, coefficient e tlase ea likhohlano le tekanyo e phahameng ea boima ba 'mele. Sena se etsa hore e be se loketseng bakeng sa lits'ebetso moo ho ts'eptjoang le ho phela nako e telele ho leng bohlokoa, joalo ka lits'ebetso tsa phetisetso ea mojaro o phahameng, metjhini e nepahetseng le lisebelisoa tse boima.

Li-gear tsa PEEK li etselitsoe ho feta lisebelisoa tsa khale tsa lisebelisoa, ho kenyeletsoa litšepe le lipolasetiki tse ling, mabapi le ho se mamelle, ho boloka boima ba 'mele le ts'ebetso ka kakaretso. Lisebelisoa tsa eona tse phahameng tsa mechine li e lumella ho mamella mocheso o feteletseng, lik'hemik'hale tse senyang le meroalo e phahameng ntle le ho senyeha, e leng se etsang hore e be se loketseng bakeng sa likopo tse mahlonoko moo ho hlōleha ho sa mamelleheng. Li-gear tsa rona tsa PEEK li khona ho sebetsa maemong a thata, li fana ka ts'episo e ke keng ea lekanngoa le ho tšoarella, ho fokotsa nako ea bareki le litšenyehelo tsa tlhokomelo.
Ntle le ts'ebetso e phahameng le ho tšoarella nako e telele, lisebelisoa tsa rona tsa PEEK li bonolo ho li kenya le ho li hlokomela. Mehaho ea eona e bobebe le e thibelang kutu e etsa hore ho be bonolo ho e tšoara le ho e kenya, ho fokotsa litšenyehelo tsa basebetsi le nako. Ho feta moo, thepa ea eona ea ho itlotsa e thusa ho fokotsa litlhoko tsa tlhokomelo, ho fokotsa litšenyehelo tsa ts'ebetso ea bareki ka kakaretso.
