Hauv ntau qhov chaw, PEEK feem ntau siv los ua kom tiav cov khoom zoo ib yam li cov khoom siv los ntawm cov hlau thiab cov ntawv thov hauv cov xwm txheej hnyav.Piv txwv li, ntau daim ntawv thov yuav tsum tau ntev compression tsis kam, hnav tsis kam, tensile zog thiab kev ua haujlwm siab, thiab corrosion kuj.Hauv kev lag luam roj thiab roj, qhov zoo ntawm cov khoom siv PEEK tuaj yeem siv tau.
Cia peb kawm txog kev ua thiab kev siv cov ntaub ntawv peek.
Ib qho ntawm cov laj thawj rau kev siv PEEK thoob plaws hauv kev siv engineering yog qhov muaj ntau yam kev xaiv thiab kev ua haujlwm, xws li machining, fused filament fabrication, 3D printing, thiab txhaj tshuaj molding, los tsim cov geometries xav tau nyob rau hauv ob qho tib si organic thiab aqueous ib puag ncig.
PEEK cov ntaub ntawv muaj nyob rau hauv daim ntawv pas nrig, compressed phaj valve, filament daim ntawv thiab pellet daim ntawv, uas yuav siv tau rau CNC machining, 3D luam ntawv thiab txhaj tshuaj molding feem.
1. PEEK CNC ua
CNC (khoos phis tawj tswj tus lej) machining muaj ntau qhov sib txawv ntawm ntau lub axis milling, tig thiab hluav taws xob tawm machining (EDM) kom tau txais qhov xav tau zaum kawg geometry.Lub ntsiab kom zoo dua ntawm cov cav tov no yog lub peev xwm los tswj lub tshuab los ntawm kev tswj siab heev los ntawm lub computer-tsim lis dej num los ua high-precision nplua machining ntawm qhov xav tau workpiece.
CNC machining muab cov xwm txheej los tsim cov geometry nyuaj hauv cov ntaub ntawv sib txawv, los ntawm cov yas mus rau hlau, thaum ua tau raws li qhov yuav tsum tau muaj cov kev txwv geometric kam rau ua.PEEK cov ntaub ntawv tuaj yeem ua tiav rau hauv cov duab geometric nyuaj, thiab tseem tuaj yeem ua tiav rau qib kho mob thiab qib PEEK qhov chaw.CNC machining muab siab precision thiab repeatability rau PEEK qhov chaw.
Vim PEEK lub siab melting point, ceev pub tus nqi thiab ceev yuav ua hauj lwm thaum lub sij hawm ua piv rau lwm yam polymers.Ua ntej pib cov txheej txheem machining, cov khoom tshwj xeeb tuav cov cai yuav tsum tau ua kom tsis txhob muaj kev ntxhov siab sab hauv thiab cov kab nrib pleb thaum lub sijhawm ua haujlwm.Cov kev cai no sib txawv raws li qib ntawm PEEK cov khoom siv thiab cov ntsiab lus tag nrho ntawm qhov no yog muab los ntawm cov chaw tsim khoom ntawm qib ntawd.
PEEK muaj zog thiab nyuaj dua li cov polymers feem ntau, tab sis softer dua li feem ntau cov hlau.Qhov no yuav tsum tau siv cov fixtures thaum lub sij hawm machining kom paub meej machining.PEEK yog cov yas yas uas muaj cua sov siab, thiab cov cua sov uas tsim los thaum ua haujlwm tsis tuaj yeem ua kom tag nrho.Qhov no yuav tsum tau siv cov thev naus laus zis tsim nyog kom tsis txhob muaj teeb meem ntau vim tias tsis muaj cua sov dissipation ntawm cov ntaub ntawv.
Cov kev ceev faj no suav nrog qhov sib sib zog nqus qhov drilling thiab siv cov dej txias txaus hauv txhua txoj haujlwm machining.Ob qho tib si petroleum-based thiab dej-based coolants tuaj yeem siv tau.
Lwm qhov tseem ceeb uas yuav tsum tau xav txog yog cov cuab yeej hnav thaum lub sijhawm ua haujlwm ntawm PEEK piv rau ob peb lwm yam khoom siv tau zoo.Kev siv cov pa roj carbon fiber reinforced PEEK qib yog qhov cuam tshuam ntau dua rau cov cuab yeej.Qhov xwm txheej no hu rau cov cuab yeej carbide rau tshuab cov qib ntawm cov khoom siv PEEK, thiab cov cuab yeej pob zeb diamond rau carbon fiber reinforced PEEK qib.Kev siv cov coolant tuaj yeem txhim kho lub neej ntawm cov cuab yeej.
2. PEEK txhaj tshuaj molding
Kev txhaj tshuaj molding yog hais txog kev tsim cov khoom siv thermoplastic los ntawm kev txhaj tshuaj molten rau hauv cov pwm ua ntej.Nws yog siv los tsim cov khoom nyob rau hauv siab ntim.Cov khoom yog melted nyob rau hauv ib tug rhuab chamber, ib tug helical ntsia hlau yog siv rau kev sib tov, thiab ces txhaj rau hauv pwm kab noj hniav qhov twg cov khoom txias los ua ib tug khoom zoo.
Granular PEEK cov khoom siv rau kev txhaj tshuaj molding thiab compression molding.Granular PEEK los ntawm cov tuam txhab sib txawv xav tau cov txheej txheem ziab me ntsis, tab sis feem ntau 3 mus rau 4 teev ntawm 150 ° C txog 160 ° C yog txaus.
Cov txheej txheem txhaj tshuaj molding tshuab tuaj yeem siv rau kev txhaj tshuaj molding ntawm PEEK cov khoom lossis pwm PEEK, vim tias cov tshuab no tuaj yeem ncav cuag qhov kub ntawm 350 ° C txog 400 ° C, uas txaus rau yuav luag txhua qib PEEK.
Kev txias ntawm pwm yuav tsum tau saib xyuas tshwj xeeb, vim tias qhov tsis sib xws yuav ua rau muaj kev hloov pauv hauv cov qauv ntawm cov khoom PEEK.Ib qho kev sib txawv ntawm cov qauv semi-crystalline ua rau cov kev hloov pauv tsis zoo hauv cov yam ntxwv ntawm PEEK.
Daim ntawv thov scenarios ntawm PEEK cov khoom
1. Cov khoom siv kho mob
Vim yog biocompatibility ntawm PEEK cov khoom, nws yog dav siv nyob rau hauv daim ntawv thov kev kho mob, nrog rau kev cog cov khoom rau hauv tib neeg lub cev rau ntau lub sij hawm.Cov khoom siv ua los ntawm cov khoom siv PEEK kuj tseem siv tau hauv cov tshuab xa tshuaj sib txawv.
Lwm daim ntawv thov kev kho mob muaj xws li kho hniav kaus mom, taw tes ntxhua khaub ncaws, cov cuab yeej kho mob, thiab cov khoom siv txha caj qaum, thiab lwm yam.
2. Aerospace qhov chaw
Vim PEEK kev sib raug zoo nrog ultra-high nqus daim ntaub ntawv, thermal conductivity thiab hluav taws xob tsis kam, thiab tshuaj tiv thaiv, cov khoom ua los ntawm PEEK yog dav siv nyob rau hauv aerospace daim ntaub ntawv vim lawv siab tensile zog.
3. Automotive qhov chaw
Bearings thiab ntau hom nplhaib kuj yog ua los ntawm PEEK.Vim PEEK qhov zoo tshaj qhov hnyav-rau-lub zog piv, nws yog siv los ua qhov chaw rau kev sib tw cav thaiv.
4. Hlau thiab cable rwb thaiv tsev / kev siv hluav taws xob
Cable rwb thaiv tsev yog ua los ntawm PEEK, uas tuaj yeem siv rau hauv cov ntawv thov xws li cov tshuab hluav taws xob hauv dav hlau hauv kev tsim khoom.
PEEK muaj cov khoom siv hluav taws xob, thermal, tshuaj lom neeg thiab hluav taws xob uas ua rau nws cov khoom xaiv rau ntau daim ntawv thov engineering.PEEK muaj nyob rau hauv ntau hom (rods, filaments, pellets) thiab tuaj yeem ua tiav los ntawm CNC machining, txhaj tshuaj molding.Goodwill Precision Machinery tau koom nrog kev ua haujlwm ntawm precision machining rau 18 xyoo.Nws muaj kev paub ntev ntev hauv ntau yam khoom siv thiab kev ua cov khoom siv tshwj xeeb.Yog tias koj muaj qhov sib thooj PEEK uas yuav tsum tau ua tiav, thov hu rau peb!Peb yuav ua siab ntev escort qhov zoo ntawm koj qhov chaw nrog peb 18-xyoo kev paub ntawm cov ntaub ntawv thiab ua technology.
