Teko ea ho thatafala ha Rockwell ea metsoako ea polymer ea PEEK

PEEK (polyetheretherketone) ke thepa e kopaneng e sebetsang hantle e entsoeng ka ho kopanya resin ea PEEK ka thepa e matlafatsang joalo ka faeba ea khabone, faeba ea khalase le liseramike. Thepa ea PEEK e nang le bothata bo phahameng e hanela ho ngoatheha le ho hohlana, 'me e loketse ho etsa likarolo le likarolo tse sa tsofaleng tse hlokang tšehetso e matla. Bothata bo phahameng ba PEEK bo e nolofalletsa ho boloka sebopeho sa eona esita le kamora khatello ea mechini le tšebeliso ea nako e telele, e leng se etsang hore e sebelisoe haholo mafapheng a lifofane, likoloi, bongaka le a mang.

Bakeng sa thepa e kopaneng ea polymer ea PEEK, ho thatafala ha Rockwell ke e 'ngoe ea matšoao a bohlokoa a ho lekola ts'ebetso ea eona. Molao-motheo oa teko ea ho thatafala ha Rockwell o thehiloe mokhoeng oa ho intša, o khethollang boleng ba ho thatafala ha thepa ka ho lekanya botebo ba ho intša bo hlahisoang ke indenter e itseng e hatellang holim'a thepa tlas'a matla a teko a boletsoeng. Ho phaella moo, ho boetse hoa hlokahala ho leka thepa ea eona ea mechini ka ho leka matla a eona a ho thaepa, matla a ho kobeha, matla a tšusumetso, jj., le ho latela maemo a machaba kapa a naha joalo ka ISO, ASTM, jj. ho etsa liteko tse tloaelehileng ho netefatsa botsitso ba boleng le ts'ebetso ea eona, le ho netefatsa polokeho le ts'epo ea ts'ebeliso ea eona masimong a amanang.

Liphetho tsa teko ea ho thatafala ha Rockwell li ka bonts'a ka ho toba bokhoni ba thepa ea PEEK polymer e kopantsoeng ho hanela ho fetoha ha polasetiki. Ho thatafala ha Rockwell ho phahameng ho bolela hore thepa e na le ho hanyetsa ho hoholo le ho tsofala, e leng habohlokoa bakeng sa tlhahiso ea likarolo tšimong ea lifofane, ho netefatsa hore likarolo li ka sebetsa ka botsitso le nako e telele libakeng tse rarahaneng tsa mechini le maemo a feteletseng; ha li sebelisoa tšimong ea likoloi ho etsa likarolo tsa enjene le likarolo tsa sistimi ea phetisetso, thepa ea PEEK e kopantsoeng e thata haholo e ka ntlafatsa bophelo ba ts'ebeletso le ts'epo ea likarolo ka katleho; lefapheng la bongaka, ha li sebelisoa ho etsa lisebelisoa tsa ho buoa kapa li-implant, ho thatafala ho loketseng ha ho netefatse feela ts'ebetso ea ts'ebetso ea sesebelisoa, empa hape ho fihlela ho lumellana ho hotle ha mechini pakeng tsa implant le lisele tsa motho. Ka nako e ts'oanang, liphetho tsa teko ea ho thatafala ha Rockwell le tsona li ka sebelisoa e le motheo oa bohlokoa oa taolo ea boleng, e sebelisoang ho lekola botsitso ba ts'ebetso ea thepa ea PEEK nakong ea ts'ebetso ea tlhahiso, le ho fumana mathata a boleng a bakoang ke liphetoho tsa thepa e tala, theknoloji ea ts'ebetso le lintlha tse ling.

Ha ho lekoa thatafalo ea Rockwell ea thepa ea PEEK, mofuta oa indenter le matla a teko li lokela ho khethoa ka nepo ho latela litšobotsi tsa thepa le mefuta e ka bang teng ea thatafalo. Likala tse sebelisoang hangata li kenyelletsa HRA, HRB, HRC, HRE, HRR, HRL, HRM, jj.

Pele ho teko e hlophisitsoeng, etsa bonnete ba hore bokaholimo ba teko ea thepa ea PEEK bo bataletse, bo boreleli, 'me ha bo na oli, lera la oxide kapa litšila tse ling ho netefatsa ho nepahala ha liphetho tsa teko. Beha sampole ka tieo bencheng ea mosebetsi ea teko ea thata ho netefatsa hore sampole ha e sisinyehe nakong ea teko. Nako le nako ha teko e etsoa, ​​​​mekhoa ea ts'ebetso ea teko ea thata e tlameha ho lateloa ka tieo, 'me matla a teko a tlameha ho sebelisoa butle ho qoba ho jara tšusumetso. Kamora hore matla a teko a tsitsisoe ka nako e boletsoeng, bala 'me u tlalehe boleng ba thata ba Rockwell bo tsamaellanang le botebo ba indentation. E le ho fumana lintlha tse emelang haholoanyane, litekanyo tse ngata hangata li etsoa libakeng tse fapaneng, joalo ka ho khetha lintlha tse 5 kapa ho feta tse fapaneng tsa teko, ebe liphetho tsa tekanyo li hlahlojoa ka lipalo-palo ho bala liparamente tse kang boleng bo tloaelehileng le ho kheloha ho tloaelehileng.
