Ikizamini gikomeye cya Rockwell ya PEEK polymer yibigize

PEEK (polyetheretherketone) nigikoresho kinini cyo gukora cyakozwe muguhuza resin ya PEEK nibikoresho byongera imbaraga nka fibre karubone, fibre y ibirahure, nubutaka. PEEK ibikoresho bifite ubukana buhanitse birwanya gushushanya no gukuramo, kandi birakwiriye gukora ibice birinda kwambara nibice bisaba inkunga ikomeye. Ubukomezi bukabije bwa PEEK butuma bugumana imiterere yabwo na nyuma yo guhangayikishwa no gukoresha igihe kirekire, bigatuma ikoreshwa cyane mu kirere, mu modoka, mu buvuzi no mu zindi nzego.

Kuri PEEK polymer yibikoresho, Gukomera kwa Rockwell nikimwe mubyingenzi byerekana gusuzuma imikorere yacyo. Ihame ryo kugerageza ubukana bwa Rockwell rishingiye kuburyo bwa indentation, bugena agaciro k'ibikoresho mugupima ubujyakuzimu bwa indentation bwakozwe na indenter yihariye ikanda hejuru yibikoresho munsi yimbaraga zipimishije. Byongeye kandi, birakenewe kandi kugerageza imiterere yubukanishi bwayo mugupima imbaraga zayo zingana, imbaraga zunamye, imbaraga zingaruka, nibindi, kandi tugakurikiza amahame mpuzamahanga cyangwa yigihugu nka ISO, ASTM, nibindi kugirango dukore ibizamini bisanzwe kugirango hamenyekane ihame ryubwiza n’imikorere, kandi harebwe umutekano n’ubwizerwe bikoreshwa mubikorwa bifitanye isano.

Ibisubizo by'ibizamini bya Rockwell birashobora kwerekana mu buryo butaziguye ubushobozi bwa PEEK polymer yibikoresho byo kurwanya ihindagurika rya plastiki. Ubukomezi bukabije bwa Rockwell bivuze ko ibikoresho bifite ibishushanyo bikomeye kandi bikarwanya kwambara, ibyo bikaba ari ingenzi cyane mu gukora ibice mu kirere cyo mu kirere, byemeza ko ibice bishobora gukora neza kandi birebire mu bihe bigoye kandi bikabije; iyo ikoreshejwe mumashanyarazi kugirango ikore ibice bya moteri nibice bya sisitemu yohereza, ubukana bwinshi PEEK yibikoresho bishobora guteza imbere ubuzima bwa serivisi no kwizerwa kwibice; murwego rwubuvuzi, iyo bikoreshejwe mugukora ibikoresho byo kubaga cyangwa gushiramo, ubukana bukwiye ntibushobora gusa gukora imikorere yicyo gikoresho gusa, ariko kandi burashobora guhuza neza nubukanishi bwiza hagati yimitsi ninyama zabantu. Muri icyo gihe, ibisubizo byikizamini cya Rockwell birashobora kandi gukoreshwa nkibanze shingiro ryo kugenzura ubuziranenge, bikoreshwa mugukurikirana ihame ryimikorere yibikoresho bya PEEK mugihe cyumusaruro, no kuvumbura vuba ibibazo byubuziranenge biterwa nimpinduka yibikoresho fatizo, ikoranabuhanga ritunganya nibindi bintu.

Mugihe cyo kugerageza ubukana bwa Rockwell bwibikoresho bya PEEK, ubwoko bwa indenter nimbaraga zo kugerageza bigomba gutoranywa muburyo bukurikije ibiranga ibintu hamwe nuburemere bushoboka. Umunzani ukunze gukoreshwa harimo HRA, HRB, HRC, HRE, HRR, HRL, HRM, nibindi.

Mbere yikizamini gisanzwe, menya neza ko igipimo cyibizamini bya PEEK kiringaniye, cyoroshye, kandi kitarimo amavuta, urwego rwa oxyde cyangwa ibindi byanduye kugirango umenye neza ibisubizo byikizamini. Shira icyitegererezo ushikamye kumurimo wakazi wikizamini kugirango umenye neza ko icyitegererezo kitimuka mugihe cyizamini. Igihe cyose ikizamini gikozwe, uburyo bwo gukora bwikizamini bugomba gukurikizwa byimazeyo, kandi imbaraga zigeragezwa zigomba gukoreshwa buhoro buhoro kugirango birinde ingaruka ziterwa. Nyuma yimbaraga zipimisha zihamye mugihe cyagenwe, soma kandi wandike agaciro gakomeye ka Rockwell gahuye nubujyakuzimu. Kugirango ubone amakuru menshi ahagarariye, ibipimo byinshi bikorerwa mubisanzwe ahantu hatandukanye, nko gutoranya amanota 5 cyangwa menshi atandukanye, hanyuma ibisubizo byo gupima bigasesengurwa muburyo bwo kubara ibipimo nkibiciro byagaciro no gutandukana bisanzwe.
