Ultem yog dab tsi?
Ultem yog cov khoom siv thermoplastic siab kub nrog cov khoom siv zoo heev, thermal, thiab hluav taws xob. Nws yog resistant rau kub kub thiab tshuaj, ua rau nws haum rau siv nyob rau hauv ntau yam industries, xws li aerospace, automotive, thiab kev kho mob.
Ultem feem ntau siv rau hauv cov ntawv thov uas xav tau lub zog siab thiab ua haujlwm ntev ntawm qhov kub siab. Nws tuaj yeem tiv taus qhov kub txog li 180 degree yam tsis muaj kev puas tsuaj loj thiab tuaj yeem tswj nws cov khoom siv hluav taws xob ntawm qhov kub thiab txias. Nws kuj muaj qhov ua tau zoo heev, txhais tau tias nws tuaj yeem tiv taus kev ntxhov siab tas li yam tsis muaj deforming lub sijhawm.
Lwm qhov zoo ntawm Ultem yog nws cov tshuaj tiv thaiv. Nws tiv taus ntau yam tshuaj, suav nrog hydrocarbons, acids, thiab bases. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv nyob rau hauv ib puag ncig hnyav uas yuav raug rau cov tshuaj no.
Ultem kuj yog ib qho zoo heev hluav taws xob insulator thiab muaj ib tug tsawg coefficient ntawm thermal expansion, uas txhais tau hais tias nws yuav tsis nthuav los yog cog lus nrog rau cov kev hloov nyob rau hauv kub. Qhov no ua rau nws haum rau siv hauv kev siv hluav taws xob thiab hluav taws xob.
Zuag qhia tag nrho, Ultem yog cov khoom siv ua haujlwm siab uas tuaj yeem tiv taus qhov kub thiab txias, hnyav tshuaj, thiab kev ntxhov siab tas li yam tsis tau poob nws cov khoom. Nws versatility ua rau nws yog ib qho tseem ceeb cov ntaub ntawv nyob rau hauv ntau industries.
Ultem siab temperatuer yas molding ua haujlwm li cas?
Ultem kub yas molding ua haujlwm los ntawm kev siv lub tshuab txhaj tshuaj molding kom yaj thiab txhaj Ultem resin rau hauv pwm kab noj hniav. Cov pwm kab noj hniav yog tom qab ntawd txias kom khov thiab tsim cov duab uas xav tau. Ultem resin muaj lub siab melting point, uas tso cai rau nws khaws nws cov duab thiab lub zog txawm nyob rau qhov kub thiab txias.
Thaum lub sij hawm txhaj tshuaj molding txheej txheem, Ultem resin yog yaj nyob rau hauv ib lub thoob los ntawm ib tug cua sov caij thiab ces txhaj nyob rau hauv lub siab mus rau hauv lub pwm kab noj hniav. Lub siab xyuas kom meej tias cov resin puv puv pwm kab noj hniav thiab tsim cov duab uas xav tau. Thaum cov pwm kab noj hniav puv lawm, nws tau txias kom khov thiab ua kom cov yas. Cov txheej txheem ua kom txias yog qhov tseem ceeb los xyuas kom meej tias cov yas khaws cov duab uas xav tau thiab lub zog.
Tom qab cov yas tau txias thiab solidified, cov pwm qhib thiab ib feem yog ejected. Tom qab ntawd cov khoom yuav dhau mus ua haujlwm ntxiv lossis sib dhos los tsim cov khoom tiav. Ultem kub yas molding yog siv nyob rau hauv ntau yam kev lag luam, xws li aerospace, automotive, electronics, thiab cov khoom siv kho mob.

Dab tsi ntawm cov yas yog ULTEM?
Ultem® (polyetherimide) yog asemi-pob tshab siab zog yas khoomuas tuaj yeem ua haujlwm hauv qhov chaw ua haujlwm kub. Ultem® tiv taus cov dej kub thiab chav dej thiab tuaj yeem tiv taus ntau zaus hauv chav autoclave. FDA ua raws qib ntawm Ultem® muaj.
Puas yog ULTEM muaj zog dua ABS?
Nylon 6, Nylon 12CF, PC ISO, PPSF / PPSU thiab ULTEM 9085 yog cov muaj zog tshaj ntawm pab pawg, tab sisPC-ABS, ABS-M30i, ABS-M30, Nylon 12 thiab ULTEM 1010 yog qhov nyuaj tshaj plaws.
Dab tsi yog qhov tshwj xeeb ntawm ULTEM?
ULTEM sawv tawm los ntawm lwm cov polymers ua haujlwm siab vim nws yogtshwj xeeb tsim kom nyob twj ywm mechanically ruaj khov nyob rau hauv huab mob. Nws tuaj yeem tiv taus qhov kub siab tshaj ntawm 217 degree rau lub sijhawm ntev thiab nyob ruaj khov ntawm qhov kub thiab txias.
ULTEM muaj zog npaum li cas?
Ultem muaj cov khoom siv kho tshuab zoo heev, suav nrog atensile zog ntawm 15,200 psi, thiab tau siv tas mus li 340ºF. Nws yog yooj yim machined thiab fabricated nrog zoo heev zog thiab rigidity thiab muaj ib tug siab dielectric zog.
Ultem siv rau dab tsi?
Ultem yog lub zog siab yas nrog cov tshuaj zoo heev & hydrolysis tsis kam, thiab cov khoom siv hluav taws xob zoo heev uas tuaj yeem tiv taus qhov kub thiab txias. Kev sib xyaw ua ke ntawm cov khoom no ua rau nws zoo tagnrho rau kev siv autoclave daim ntaub ntawv, cov khoom siv hluav taws xob siab hluav taws xob, cov khoom siv dav hlau dav hlau, thiab kev siv microwave.
Puas yog Ultem yog thermoplastic?
Ultem yog lub zog siab thermoplastic nrog cov tshuaj zoo heev & hydrolysis tsis kam nrog rau cov khoom siv hluav taws xob zoo. Nws muaj ib qho zoo tshaj plaws dielectric zog ntawm tej thermoplastic.
