Teko ea boima ba Rockwell ea likarolo tsa PEEK polymer

PEEK (polyetheretherketone) ke lisebelisoa tse nang le ts'ebetso e phahameng tse entsoeng ka ho kopanya resin ea PEEK e nang le lisebelisoa tse matlafatsang tse kang carbon fiber, glass fiber, le ceramics. Lisebelisoa tsa PEEK tse nang le boima bo phahameng li hanyetsana le mengoapo le makhopho, 'me li loketse ho etsa likarolo tse sa senyeheng le likarolo tse hlokang tšehetso e matla haholo. Boima bo phahameng ba PEEK bo e nolofalletsa ho boloka sebōpeho sa eona esita le ka mor'a khatello ea mechine le tšebeliso ea nako e telele, e leng ho etsang hore e sebelisoe haholo sebakeng sa lifofane, likoloi, tsa bongaka le tse ling.

Bakeng sa lisebelisoa tse kopaneng tsa PEEK polymer, boima ba Rockwell ke e 'ngoe ea matšoao a bohlokoa a ho lekola ts'ebetso ea eona. Molao-motheo oa teko oa ho thatafala ha Rockwell o ipapisitse le mokhoa oa indentation, o khethollang boleng ba boima ba thepa ka ho lekanya botebo ba indentation bo hlahisoang ke inndenter e itseng e hatellang holim'a thepa tlas'a matla a teko a boletsoeng. Ntle le moo, hoa hlokahala ho leka lisebelisoa tsa eona tsa mochini ka ho lekola matla a eona a thata, matla a ho kobeha, matla a ts'usumetso, joalo-joalo, le ho latela litekanyetso tsa machabeng kapa tsa naha joalo ka ISO, ASTM, jj.

Liphetho tsa liteko tsa Rockwell hardness li ka bonts'a ka kotloloho bokhoni ba lisebelisoa tse kopaneng tsa PEEK polymer ho hanela deformation ea polasetiki. Boima bo phahameng ba Rockwell bo bolela hore thepa e na le khanyetso e matla le ea ho roala, e leng ea bohlokoa bakeng sa tlhahiso ea eona ea likarolo sebakeng sa sefofane, ho etsa bonnete ba hore likarolo li ka sebetsa ka mokhoa o tsitsitseng le oa nako e telele libakeng tse rarahaneng tsa mechine le maemo a feteletseng; ha e sebelisoa tšimong ea likoloi ho etsa likarolo tsa enjene le likarolo tsa tsamaiso ea phetisetso, lisebelisoa tse kopantsoeng tsa PEEK tse thata haholo li ka ntlafatsa bophelo ba tšebeletso le ho tšepahala ha likarolo; lefapheng la bongaka, ha le sebelisoa ho etsa lisebelisoa tsa ho buoa kapa li-implants, boima bo loketseng bo ke ke ba tiisa feela ts'ebetso ea ts'ebetso ea sesebelisoa, empa hape bo kopana le ho lumellana hantle ha mochine pakeng tsa ho kenngoa le lisele tsa motho. Ka nako e ts'oanang, liphetho tsa liteko tsa Rockwell hardness li ka boela tsa sebelisoa e le motheo oa bohlokoa oa taolo ea boleng, e sebelisetsoang ho shebella botsitso ba ts'ebetso ea thepa ea PEEK nakong ea ts'ebetso ea tlhahiso, le ho fumana kapele mathata a boleng a bakoang ke liphetoho tsa thepa e tala, theknoloji ea ho sebetsa le lintlha tse ling.

Ha ho hlahlojoa boima ba Rockwell ba thepa ea PEEK, mofuta oa indenter le matla a teko li lokela ho khethoa ka mokhoa o utloahalang ho latela litšobotsi tsa thepa le mefuta e ka bang thata ea boima. Likala tse sebelisoang hangata li kenyelletsa HRA, HRB, HRC, HRE, HRR, HRL, HRM, joalo-joalo.

Pele ho tlhahlobo e hlophisitsoeng, etsa bonnete ba hore bokaholimo ba tlhahlobo ea thepa ea PEEK bo bataletse, bo boreleli, 'me ha bo na oli, oxide layer kapa litšila tse ling ho netefatsa bonnete ba sephetho sa liteko. Beha sampuli ka tieo holim'a benche ea mosebetsi oa tester ea boima ho netefatsa hore sampuli ha e tsamaee nakong ea tlhahlobo. Nako le nako ha tlhahlobo e etsoa, ​​mekhoa ea ts'ebetso ea "hardness tester" e tlameha ho lateloa ka thata, 'me matla a teko a tlameha ho sebelisoa butle ho qoba ho kenya letsoho. Ka mor'a hore matla a teko a tsitsa ka nako e behiloeng, bala le ho rekota boleng ba boima ba Rockwell bo tsamaellanang le botebo ba indentation. Bakeng sa ho fumana lintlha tse ngata tse emetseng, litekanyo tse ngata hangata li etsoa libakeng tse fapaneng, joalo ka ho khetha lintlha tse 5 kapa ho feta tse fapaneng tsa tlhahlobo, 'me liphetho tsa litekanyo li hlahlojoe ho ea ka lipalo-palo ho bala liparamente tse kang boleng bo tloaelehileng le ho kheloha ho tloaelehileng.
