Sab Hauv Nto Yog Dab Tsi?

Cov npoo ntawm lub ntsej muag qhia txog cov yam ntxwv ntawm ib cov khoom tom qab nws tau raug rau qee hom kev tsim khoom lossis kev hloov kho. Cov kws tsim khoom tsim khoom tsim khoom lag luam feem ntau npaj cov phiaj xwm raws li cov yam ntxwv paub ntawm ib qho hlau. Piv txwv li, cov neeg tsim qauv no paub tias ib qho tshwj xeeb steel alloy muaj qib tsim theem ntawm lub zog lossis tawv. Tom qab cov khoom hloov kho tau hloov lawm, cov khoom qub qub no yuav tsis siv ntxiv lawm, vim ntau txoj kev tsim khoom tsim tau hloov mus tas li ntawm cov khoom. Cov npoo ncaj ncees pab cov tib neeg no txiav txim siab seb cov khoom yuav hloov pauv li cas rau qee yam, thiab yam khoom' cov khoom tshiab tau muab piv rau nws cov qub.

Qhov kev ncaj ncees saum npoo ntawm ib qho khoom siv yog ua los ntawm ob qhov pib yooj yim. Lawv suav nrog thaj chaw thau sab hauv thiab sab hauv lub ntsej muag ntawm cov khoom. Topography qhia kev hloov pauv sab nrauv ntawm cov khoom siv, thiab suav nrog cov khoom xws li smoothness, ua pob lossis vuag, pitting thiab cov kab nrib pleb. Sab hauv sab hauv qhov chaw nyob tsuas yog hloov sab nraud nkaus xwb, xws li deformation thiab kev hloov pauv ntawm lub zog lossis tawv. Lawv tsis suav nrog kev hloov sab hauv tob hauv lub plawv ntawm ib qho khoom siv, tab sis theej hauv txheej hauv qab sab saum npoo.

Thaum kawg, feem ntau cov txheej txheem tsim khoom yuav muaj qee qhov cuam tshuam rau kev ncaj ncees saum npoo, txawm hais tias qhov no tsis yog' t yeej ib txwm muaj qhov xwm txheej. Tus qauv tshuab dhos ua haujlwm, sib tsoo lossis milling, thaum ua tiav zoo, tsis muaj kev cuam tshuam cov ncaj ncees saum npoo. Thaum cov txheej txheem no tau ua los siv cov kev siv tsis zoo los yog cov cuab yeej npub, txawm li cas los xij, lawv tuaj yeem muaj kev cuam tshuam loj ntawm cov khoom siv. Kev kub dhau, txias lossis ceev lossis kev ua haujlwm kuj tuaj yeem ua rau muaj qhov hloov pauv tseem ceeb.

Tus txheej txheem sib cav ntau yuav luag ib txwm muaj qee yam ua tas mus li ntawm qhov chaw ncaj ncees. Lawv yuav suav nrog kev kho mob electro, xws li plating, uas ntxiv ntxiv cov hlau tsis tu ncua rau cov hlau, lossis tshuaj kho mob. Yuav luag txhua yam kev kho mob, nrog rau cov cua sov ntev dhau lawm, tuaj yeem hloov cov khoom hauv nws qib molecular, coj kev hloov pauv tsis tau rau nws tus qauv. Kev hlawv hluav taws thiab lwm hom deformation kuj tseem ua rau muaj kev hloov pauv, tshwj xeeb tshaj yog thaum thov rau plastics.

Hloov pauv ntawm qhov chaw ncaj ncees tuaj yeem yog qhov zoo lossis qhov tsis zoo. Cov kev hloov pauv tsis zoo tuaj yeem txhais tau tias cov khoom siv tsis tuaj yeem siv raws li xav tau. Piv txwv li, cov hlau kem raug rau quenching yuav kawg nkig los txhawb tus qauv. Cov kev hloov pauv zoo yog cov uas muab cov ntaub ntawv qhov xav ua tiav lossis zoo li, xws li hlawv kom tawm ntawm cov khoom ntxhib. Kev hloov pauv zoo ntawm thaj chaw ncaj ncees kuj suav nrog cov khoom uas txhim kho lub zog xws li tawv tawv, lub zog, lossis cov dej noo tsis kam.
