PPSU, lub npe tshawb fawb ntawm polyphenylene sulfone resin, yog amorphous thermoplastic nrog siab transparency thiab hydrolytic stability, thiab cov khoom tuaj yeem tiv taus cov tshuaj tua kab mob dua.
PPSU muaj ntau tshaj li polysulfone (PSU), polyethersulfone (PES) thiab polyetherimide (PEI).
Kev siv PPSU
1. Cov khoom siv hauv tsev thiab cov thawv ntim khoom noj: tuaj yeem siv los tsim cov khoom siv microwave qhov cub, kas fes rhaub, humidifiers, tshuab ziab plaub hau, ntim khoom noj, lub raj mis me me, thiab lwm yam.
2. Cov khoom lag luam digital: tsis yog tooj liab, zinc, txhuas thiab lwm yam khoom siv hlau, kev tsim cov rooj plaub, cov khoom siv kho kom zoo nkauj sab hauv thiab cov tshuab luam ntawv, cov khoom siv koob yees duab thiab lwm yam kev ua haujlwm zoo.
3. Kev lag luam kev lag luam: feem ntau yog siv iav fiber reinforced specifications, cov khoom muaj cov yam ntxwv ntawm creep kuj, hardness, seem stability, thiab lwm yam., haum rau zus tau tej cov bearings brackets thiab mechanical qhov chaw plhaub thiab lwm yam.
4. Kev kho mob thiab kev noj qab haus huv: zoo heev rau cov cuab yeej kho hniav thiab phais, cov thawv tshuaj tua kab mob (daim phiaj) thiab ntau yam khoom siv kho mob uas tsis yog tib neeg implantable.

Ob peb lub ntsiab lus yuav tsum tau them sai sai rau thaum tsim PPSU cov khoom thiab pwm
1. Lub fluidity ntawm PSU yaj yog tsis zoo, thiab qhov ratio ntawm yaj ntws ntev mus rau phab ntsa thickness tsuas yog hais txog 80. Yog li ntawd, cov phab ntsa thickness ntawm PSU cov khoom yuav tsum tsis txhob tsawg tshaj li 1.5 hli, thiab feem ntau ntawm lawv yog siab tshaj 2 hli.
PSU cov khoom yog rhiab heev rau notches, yog li arc hloov yuav tsum tau siv ntawm txoj cai los yog mob ces kaum. Lub molding shrinkage ntawm PSU yog qhov ruaj khov, uas yog 0.4% -0.8%, thiab cov kev taw qhia yaj ntws yog qhov zoo ib yam li qhov kev taw qhia ntsug. Lub kaum sab xis yuav tsum yog 50: 1. Yuav kom tau txais cov khoom ci thiab huv si, qhov roughness ntawm cov pwm kab noj hniav yuav tsum muaj ntau tshaj Ra0.4. Txhawm rau kom yooj yim rau cov dej ntws, cov pwm ntawm cov pwm yuav tsum yog luv thiab tuab, nws txoj kab uas hla yog tsawg kawg yog 1/2 ntawm cov khoom tuab, thiab muaj txoj kab nqes ntawm 3 ° ~ 5 °. Ntu ntu ntawm shunt channel yuav tsum yog arc lossis trapezoid kom tsis txhob muaj qhov khoov.
2. Daim ntawv ntawm lub rooj vag tuaj yeem txiav txim siab los ntawm cov khoom. Tab sis qhov loj me yuav tsum loj npaum li qhov ua tau, qhov ncaj ntawm lub rooj vag yuav tsum luv li sai tau, thiab nws qhov ntev tuaj yeem tswj tau ntawm 0.5 ~ 1.0mm. Txoj hauj lwm ntawm qhov chaw noj mov yuav tsum tau teem rau ntawm phab ntsa tuab.
3. Teem lub qhov txias txaus ntawm qhov kawg ntawm lub sprue. Vim tias cov khoom PSU, tshwj xeeb tshaj yog cov khoom siv phab ntsa nyias, xav tau kev txhaj tshuaj ntau dua thiab kev txhaj tshuaj sai dua, cov qhov tso pa zoo lossis cov zawj yuav tsum tau teeb tsa kom thiaj li tso pa tawm hauv pwm hauv lub sijhawm. Qhov tob ntawm cov vents los yog grooves yuav tsum tau tswj hauv qab 0.08mm.
4. Kev teeb tsa ntawm pwm kub yuav tsum muaj txiaj ntsig los txhim kho cov dej ntws ntawm PSU yaj thaum lub sij hawm ua zaj duab xis. Cov pwm kub tuaj yeem siab txog 140 ℃ (tsawg kawg 120 ℃).
