Rockwell hardness test ntawm PEEK polymer composites

PEEK (polyetheretherketone) yog cov khoom siv ua haujlwm siab ua los ntawm kev sib xyaw PEEK resin nrog cov khoom siv ntxiv xws li carbon fiber, iav fiber ntau, thiab ceramics. PEEK cov khoom uas muaj zog dua yog cov resistant rau khawb thiab puas, thiab tsim nyog rau kev tsim cov khoom hnav-resistant thiab qhov chaw uas yuav tsum tau muaj kev txhawb zog siab. Lub siab tawv ntawm PEEK ua rau nws tswj tau nws cov duab txawm tias tom qab kev ntxhov siab thiab kev siv lub sijhawm ntev, ua rau nws siv dav hauv aerospace, tsheb, kev kho mob thiab lwm yam haujlwm.

Rau PEEK polymer cov ntaub ntawv sib xyaw, Rockwell hardness yog ib qho ntawm cov cim tseem ceeb rau kev ntsuas nws qhov kev ua tau zoo. Lub hauv paus ntsiab lus ntawm kev ntsuam xyuas ntawm Rockwell hardness yog raws li txoj kev indentation, uas txiav txim siab hardness tus nqi ntawm cov khoom los ntawm kev ntsuas qhov indentation qhov tob uas ua los ntawm ib tug tshwj xeeb indenter nias rau hauv cov khoom nto raws li ib qho kev xeem quab yuam. Tsis tas li ntawd, nws tseem yuav tsum tau kuaj nws cov khoom siv los ntawm kev sim nws lub zog tensile, dabtsi yog khoov lub zog, cuam tshuam lub zog, thiab lwm yam, thiab ua raws li cov qauv thoob ntiaj teb lossis lub teb chaws xws li ISO, ASTM, thiab lwm yam.

Cov txiaj ntsig ntawm Rockwell hardness test tuaj yeem cuam tshuam ncaj qha rau lub peev xwm ntawm PEEK polymer cov ntaub ntawv los tiv thaiv cov yas deformation. Rockwell hardness siab dua txhais tau hais tias cov khoom muaj zog khawb thiab hnav tsis kam, uas yog ib qho tseem ceeb rau nws cov khoom tsim nyob rau hauv aerospace teb, xyuas kom meej tias cov khoom yuav ua hauj lwm ruaj khov thiab ntev nyob rau hauv complex mechanical ib puag ncig thiab huab cua puag; Thaum siv nyob rau hauv lub automotive teb los tsim cav qhov chaw thiab kis tau tus mob qhov chaw, high-hardness PEEK composite cov ntaub ntawv yuav ua tau zoo txhim kho lub neej kev pab cuam thiab kev cia siab ntawm qhov chaw; Hauv kev kho mob, thaum siv los tsim cov cuab yeej phais lossis cov khoom cog, qhov tsim nyog hardness tuaj yeem tsis tsuas yog ua kom muaj kev ua haujlwm ntawm cov cuab yeej, tab sis kuj ua tau raws li cov khoom siv zoo sib xws ntawm cov khoom cog thiab tib neeg cov ntaub so ntswg. Nyob rau tib lub sijhawm, Rockwell hardness test results kuj tseem siv tau los ua lub hauv paus tseem ceeb rau kev tswj kom zoo, siv los saib xyuas kev ruaj ntseg ntawm PEEK cov ntaub ntawv kev ua tau zoo thaum lub sij hawm tsim khoom, thiab kom nrhiav tau cov teeb meem zoo tshwm sim los ntawm kev hloov pauv ntawm cov khoom siv raw, kev siv tshuab thiab lwm yam.

Thaum kuaj Rockwell hardness ntawm PEEK cov ntaub ntawv, hom indenter thiab kev xeem quab yuam yuav tsum raug xaiv raws li tus yam ntxwv ntawm cov khoom thiab cov hardness ntau yam. Feem ntau siv cov nplais xws li HRA, HRB, HRC, HRE, HRR, HRL, HRM, thiab lwm yam.

Ua ntej qhov kev xeem, xyuas kom meej tias qhov chaw xeem ntawm cov khoom PEEK yog tiaj tus, du, thiab tsis muaj roj, oxide txheej los yog lwm yam impurities los xyuas kom meej qhov tseeb ntawm qhov kev xeem. Muab cov qauv kom ruaj khov rau ntawm qhov chaw ua haujlwm ntawm lub hardness tester kom paub tseeb tias cov qauv tsis txav thaum lub sijhawm kuaj. Txhua zaus qhov kev sim ua tiav, cov txheej txheem kev khiav hauj lwm ntawm lub hardness tester yuav tsum tau ua raws li nruj me ntsis raws li, thiab kev xeem quab yuam yuav tsum tau siv maj mam kom tsis txhob muaj kev cuam tshuam kev thauj khoom. Tom qab qhov kev sim quab yuam tau ruaj khov rau lub sijhawm teev tseg, nyeem thiab sau cov Rockwell hardness tus nqi sib xws rau qhov tob indentation. Txhawm rau kom tau txais cov ntaub ntawv sawv cev ntau dua, ntau qhov kev ntsuas feem ntau tau ua nyob rau ntawm qhov chaw sib txawv, xws li xaiv 5 lossis ntau dua cov ntsiab lus sib txawv, thiab tom qab ntawd cov txiaj ntsig ntsuas tau raug txheeb xyuas los suav cov ntsuas xws li tus nqi nruab nrab thiab tus qauv sib txawv.
