Ikizamini cyo gukomera kwa Rockwell cya PEEK polymer composite

PEEK (polyetheretherketone) ni ibikoresho bivanze bikozwe mu buryo bworoshye kandi bukozwe mu guteranya resin ya PEEK n'ibikoresho biyikomeza nk'imigozi ya karuboni, imigozi y'ibirahure, na ceramic. Ibikoresho bya PEEK bifite ubukana bwinshi birwanya gushwanyagurika no kwangirika, kandi birakwiriye mu gukora ibice n'ibice bidashobora kwangirika bisaba inkunga ikomeye. Ubukana bwinshi bwa PEEK butuma igumana imiterere yayo nubwo yakoreshejwe igihe kirekire, bigatuma ikoreshwa cyane mu by'indege, imodoka, ubuvuzi n'ibindi.

Ku bikoresho bya PEEK polymer, ubukana bwa Rockwell ni kimwe mu bimenyetso by'ingenzi bigena imikorere yabyo. Ihame ryo gupima ubukana bwa Rockwell rishingiye ku buryo bwo gupima ubukana bwabyo, bugena agaciro k'ubukana bwabyo binyuze mu gupima ubujyakuzimu bw'ibikoresho bikozwe n'icyuma cyihariye gikandagira ku buso bw'ibikoresho munsi y'imbaraga zagenwe zo gupima. Byongeye kandi, ni ngombwa gupima imiterere yabyo binyuze mu gupima imbaraga zabyo zo gukurura, imbaraga zo kunama, imbaraga z'ingaruka, nibindi, no gukurikiza amahame mpuzamahanga cyangwa ay'igihugu nka ISO, ASTM, nibindi kugira ngo hakorwe ibizamini bisanzwe kugira ngo harebwe ko ubuziranenge n'imikorere yabyo bihamye, no kwemeza umutekano n'ukuri kw'ikoreshwa ryabyo mu nzego zijyanye nabyo.

Ibisubizo by'ikizamini cy'ubukomere bwa Rockwell bishobora kugaragaza neza ubushobozi bw'ibikoresho bya PEEK polymer bya pulasitiki mu kurwanya kwangirika kwa pulasitiki. Ubukomere bwinshi bwa Rockwell bivuze ko ibikoresho bifite ubushobozi bwo kwangirika no kwangirika gukomeye, ari ingenzi mu gukora ibice mu rwego rw'indege, bikerekana ko ibice bishobora gukora neza kandi igihe kirekire mu bidukikije bigoye kandi bigoye; iyo bikoreshejwe mu rwego rw'imodoka mu gukora ibice bya moteri n'ibice bya sisitemu yo gutwara ibintu, ibikoresho bya PEEK ...

Mu gihe cyo gupima ubukana bwa Rockwell bw'ibikoresho bya PEEK, ubwoko bwa indenter n'imbaraga zo gupima bigomba gutoranywa neza hakurikijwe imiterere y'ibikoresho n'urwego rw'ubukana rushoboka. Ibipimo bikunze gukoreshwa birimo HRA, HRB, HRC, HRE, HRR, HRL, HRM, nibindi.

Mbere yo gukora ikizamini cyemewe, menya neza ko ubuso bw'ikizamini cy'ibikoresho bya PEEK buringaniye, buroroshye, kandi nta mavuta, urwego rwa okiside cyangwa indi myanda ihari kugira ngo umenye neza ko ibisubizo by'ikizamini ari ukuri. Shyira icyitegererezo neza ku ntebe y'ikizamini cy'ubukana kugira ngo umenye neza ko icyitegererezo kidahinduka mu gihe cy'ikizamini. Igihe cyose ikizamini gikozwe, inzira z'imikorere y'ikizamini cy'ubukana zigomba gukurikizwa neza, kandi imbaraga z'ikizamini zigomba gukoreshwa buhoro buhoro kugira ngo hirindwe ko ingaruka zibaho. Nyuma y'uko imbaraga z'ikizamini zihamye mu gihe cyagenwe, soma kandi wandike agaciro k'ubukana bwa Rockwell gahuye n'ubujyakuzimu bw'aho amazi anyura. Kugira ngo ubone amakuru menshi agaragara, ibipimo byinshi bikorerwa ahantu hatandukanye, nko guhitamo ingingo 5 cyangwa zirenga z'ikizamini, hanyuma ibisubizo by'ibipimo bigasesengurwa mu buryo bw'ibarurishamibare kugira ngo harebwe ibipimo nk'agaciro k'ikigereranyo n'itandukaniro risanzwe.
