Cov ntaub ntawv yas pwm yog dab tsi?

Muaj ntau homyas pwmcov ntaub ntawv, uas tuaj yeem muab faib ua ntau hom raws li cov qauv sib txawv.Ntawm no yog tsib pawg:

(1) Kev faib tawm raws li kev siv yam ntxwv:
Raws li cov yam ntxwv ntawm kev siv, cov ntaub ntawv yas pwm tuaj yeem muab faib ua cov khoom siv pwm pwm, cov ntaub ntawv pwm pob tshab, yooj yim tso pwm cov ntaub ntawv, yooj yim rau txheej pwm cov ntaub ntawv, hnav cov ntaub ntawv pwm resistant.

(2) Kev faib tawm raws li kev tsim khoom:
Raws li cov txheej txheem tsim, cov ntaub ntawv yas pwm tuaj yeem muab faib ua cov khoom siv pwm, forging pwm cov ntaub ntawv, stamping pwm cov ntaub ntawv, cov khoom siv pwm, thiab lwm yam.

(3) Kev faib tawm raws li cov khoom siv:
Raws li cov khoom siv, cov ntaub ntawv yas pwm tuaj yeem muab faib ua cov khoom pwm hlau, cov khoom siv pwm tsis yog xim hlau thiab cov khoom pwm sib xyaw.Cov ntaub ntawv pwm hlau feem ntau suav nrog hlau puag alloy, npib tsib xee puag alloy, tooj liab puag alloy, thiab lwm yam. Cov khoom siv pwm tsis yog hlau feem ntau suav nrog yas, roj hmab, ceramics, thiab lwm yam.;Cov ntaub ntawv sib xyaw Pwm cov ntaub ntawv yog cov hlau thiab cov khoom tsis yog hlau.

(4) Classification raws li melting point:
Raws li lub ntsiab lus melting, cov ntaub ntawv yas pwm tuaj yeem muab faib ua cov khoom siv uas tsis tshua muaj melting point pwm thiab cov ntaub ntawv siab melting point pwm.Tsawg melting point pwm cov ntaub ntawv feem ntau suav nrog zinc alloy, aluminium alloy, thiab lwm yam. High melting point pwm cov ntaub ntawv yog cov hlau, stainless hlau, superalloy thiab lwm yam.

(5) Kev faib tawm los ntawm kev sib xyaw:
Raws li qhov muaj pes tsawg leeg,yas pwmcov ntaub ntawv tuaj yeem muab faib ua ib qho khoom pwm thiab cov khoom sib xyaw pwm.Cov khoom siv ib leeg yog tsim los ntawm tib cov khoom;Cov khoom siv sib xyaw pwm feem ntau yog ua los ntawm ob lossis ntau yam khoom sib txawv.

Nws yuav tsum raug sau tseg tias tseem muaj qhov sib txawv ntawm cov txheej txheem kev faib tawm sib txawv, thiab cov khoom pwm tuaj yeem muaj cov yam ntxwv ntawm ntau txoj kev faib tawm tib lub sijhawm.Nyob rau tib lub sijhawm, nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv yas pwm tshiab kuj tau tshwm sim, thiab lawv txoj kev faib tawm tau nthuav dav thiab hloov kho tas li.
