Dab tsi yog cov khoom ntawm yas pwm kab noj hniav?

Cov khoom siv yas pwm kab noj hniav yog hais txog cov khoom siv los tsim cov kab noj hniav ntawm cov pwm yas.Cov pwm yas sib txawv siv cov ntaub ntawv sib txawv kom tau raws li cov kev xav tau sib txawv thiab cov kev xav tau.

Cov hauv qab no yog 5 yam khoom siv yas pwm kab noj hniav:

(1) Cov khoom siv hlau: Cov cuab yeej hlau yog ib qho ntawm cov khoom siv yas pwm kab noj hniav feem ntau siv.Nws muaj qhov zoo hardness, hnav tsis kam thiab corrosion kuj, thiab tuaj yeem tiv taus cov txheej txheem txhaj tshuaj molding nyob rau hauv qhov kub thiab txias.Cov cuab yeej siv hlau muaj xws li P20 (lub npe hu ua 3Cr2Mo hauv Suav teb), 718 (hu ua 3Cr2NiMo hauv Suav teb) thiab lwm yam.

(2) Cov khoom siv steel hlau: Stainless hlau yog lwm cov khoom siv yas pwm kab noj hniav.Stainless hlau muaj kev tiv thaiv corrosion siab thiab oxidation tsis kam, uas yog tsim rau kev kho mob ntawm cov ntaub ntawv yas uas muaj acidic los yog alkaline cov khoom xyaw.Cov khoom siv stainless hlau feem ntau yog SUS420, SUS304 thiab lwm yam.

(3) Cov khoom siv aluminium alloy: Aluminium alloy yog lub teeb yuag thiab zoo thermal conductivity khoom, tsim rau kev tsim pwm loj lossis pwm uas tsis muaj qhov hnyav.Aluminium alloys muaj cov thermal conductivity siab, uas pab ua kom cov yas txias txias.Cov ntaub ntawv txhuas txhuas yog ADC12, 6061 thiab lwm yam.

(4) Cov khoom siv tooj liab: tooj liab alloy muaj cov thermal conductivity zoo thiab hnav tsis kam, haum rau kev tsim pwm nyob rau hauv qhov kub thiab txias.Copper alloys tuaj yeem muab cov cua sov zoo dua thiab pab tswj cov cua txias ntawm cov yas.Cov khoom siv tooj liab feem ntau yog H13, CuBe2 thiab lwm yam.

(5) Cov ntaub ntawv Polymer: Ntxiv rau cov ntaub ntawv hlau, muaj qee cov ntaub ntawv polymer tuaj yeem siv los tsim cov kab noj hniav ntawm cov pwm yas.Piv txwv li, polyimide (PI), polytetrafluoroethylene (PTFE) thiab lwm yam muaj zoo heev kub thiab corrosion kuj, haum rau kev kho mob ntawm kub kub plastics los yog tshwj xeeb cov ntaub ntawv yas.

Nws yog ib qho tsim nyog los xaiv qhov tsim nyogyas pwmkab noj hniav raws li cov kev thov tshwj xeeb thiab cov yam ntxwv ntawm cov khoom siv yas.Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv thiab cov peev txheej ntawm daim ntawv thov, rau cov khoom siv sib txawv thiab cov kev xav tau ntau lawm, xaiv cov khoom siv kab noj hniav yog qhov tseem ceeb los xyuas kom meej pwm kev ua tau zoo thiab lub neej.
