Yas Vajntxwv-Polyetherketone PEEK

PEEK yog tsim los ntawm kev txuas ntxiv extrusion: PEEK pas nrig, PEEK phaj, PEEK raj, PEEK zaj duab xis, PEEK daim ntawv, PEEK filament, PEEK capillary; polyetheretherketone (PEEK) yog ib zaj duab xis txuas ntxiv nrog crystallinity qis, thiab feem ntau yuav tsum tau ua ke nrog carbon fiber, iav fiber, melamine fiber thiab lwm yam ntaub ntawv rau kev siv. Composite.Uncompounded polyetheretherketone (PEEK) zaj duab xis tuaj yeem ncab thiab kho cua sov kom txhim kho lub zog thiab tiv taus cua sov. Cov ncab thiab kho cua sov polyetheretherketone (PEEK) zaj duab xis muaj qhov melting point 80 ℃ siab dua li ntawm PET zaj duab xis.

Cov txiaj ntsig thiab qhov tsis zoo ntawm PEEK

Qhov zoo ntawm PEEK

Kev tiv thaiv corrosion, tiv thaiv kev laus; kev tiv thaiv solubility; kub siab, zaus siab thiab voltage siab ua tau zoo; ob qho tib si toughness thiab rigidity; qhov tseeb qhov loj me xav tau; hluav taws xob tsis kam, hnav tsis kam, corrosion tsis kam; kev tiv thaiv hydrolysis, kub siab thiab siab siab tseem tuaj yeem tswj tau cov yam ntxwv zoo heev; hloov hlau ua cov khoom siv fiber ntau optical; zoo hnav tsis kam, antistatic hluav taws xob rwb thaiv tsev; siab mechanical zog xav tau cov khoom; tsawg pa phem thiab cov pa roj lom.

Qhov tsis zoo ntawm PEEK

Kev txhaj tshuaj, molding thiab #profile extrusion cov txheej txheem mob hnyav heev

Cov chaw siv tseem ceeb ntawm PEEK

PEEK tiv taus hydrolysis thiab yooj yim rau kev ua, thiab lwm yam, thiab tau siv rau hauv aerospace, kev tsim tsheb, hluav taws xob thiab hluav taws xob, kev kho mob thiab kev ua zaub mov; nws yog dav siv hauv tshuab, petrochemical, nuclear fais fab, kev thauj mus los ntawm tsheb ciav hlau thiab lwm yam teb, xws li compressor valve plates, high-pressure steam ball valve seats, bearing cages, tshuaj twj tso kua mis iav, sliding bearings, seals, piston rings, sliding shoes thiab lwm yam khoom siv tshuab, cov khoom zoo sib xws, lub neej ntev, tab sis kuj txo cov suab nrov ua haujlwm ntawm lub tshuab. Tsis tas li ntawd, vim PEEK muaj cov khoom siv hluav taws xob zoo, nws tseem tuaj yeem tswj tau cov khoom siv hluav taws xob zoo hauv qab qhov kub thiab txias, voltage siab thiab av noo siab.

Cov yam ntxwv ntawm PEEK

Ua ib lub yas engineering semi-crystalline, PEEK tsis yaj hauv yuav luag txhua cov kuab tshuaj tsuas yog cov kua qaub sulfuric uas muaj concentrated xwb, yog li nws feem ntau siv los ua cov phaj valve compressor, piston rings, seals, thiab ntau yam twj tso kua mis thiab cov khoom siv valve. PEEK resin kuj tseem tuaj yeem autoclaved rau txog li 3000 lub voj voog ntawm 134 ℃. Cov yam ntxwv no ua rau nws tsim nyog rau kev tsim cov khoom siv phais thiab kho hniav nrog cov kev xav tau siab sterilization thiab siv ntau zaus.

Kev ua PEEK

● Kev siv tshuab extrusion thiab kev tswj qhov kub ntawm lub cub tawg:
 #Kev rho tawm Cov txheej txheem molding suav nrog cov hlau txheej, cov yeeb nkab profile, daim ntawv zaj duab xis thiab kev tsim monofilament. Txhua lub extruder yog cov extruder ib leeg ntsia hlau, tab sis cov khoom siv downstream xws li lub taub hau, tuag, teeb tsa, txias, traction, ncab, calendering, thiab winding tsis zoo ib yam.
Lub tshuab cua sov hlau lossis ceramic ntawm lub thoob yuav tsum npog tag nrho cov nplaim ntawm lub thoob hlau thiab tuaj yeem ua kom sov txog 400 ℃ ± 2 ℃ kom ntseeg tau tias qhov kub sib npaug.

● Kub ntawm pwm:
PEEK molding kub yog 320 degrees ~ 390 degrees, ci kub yog 160 ~ 1855H ~ 8H, pwm kub yog 140 ~ 180, pwm kub ntawm cov khoom no siab dhau, thiab kev puas tsuaj rau #extruder s ntsia hlau loj dua. Thaum teeb tsa qhov ceev ntawm lub ntsia hlau, qhov ceev yuav tsum tsis txhob ceev dhau, thiab lub siab txhaj tshuaj yog 100 ~ 130MPa. Qhov ceev txhaj tshuaj yog 40 ~ 80.

● Cov lus qhia txog kev cai lij choj:
Tom qab ua tiav cov pwm lawm, lub hau yuav tsum tau ntxuav sai sai nrog PE wax raws sijhawm, thiab cov khoom siv PEEK yuav tsum tsis txhob cia nyob hauv lub hau. Cov ntsia hlau PVC uas tau extruded los ntawm PEEK tab sis compressed tas li tsis pom zoo, vim tias lub hau tsis muaj thaj chaw pub mis, uas ua rau cov yas compressed sai li sai tau thaum nws nkag mus rau hauv lub thoob, ua rau lub hau ntswj torque ntau dhau. Kev lim ntawm PEEK yaj muaj qhov cuam tshuam zoo rau qhov sib xws ntawm cov khoom siv lub cev ntawm extrusion; siv 20/60/250/60/ Lub cuab yeej lim dej ua ke uas muaj 250 mesh stainless hlau xaim braided mesh tuaj yeem tau txais cov txiaj ntsig zoo dua rau kev lim cov dej ntws tas li.
