(1) High Wear Resistance
iav fibers thiab inorganic fillers yog dav siv nyob rau hauv yas formulations los txhim kho rigidity thiab mechanical zog. Thaum cov additives no tau qhia, lawv nkag mus rau hauv cov pwm kab noj hniav ntawm kev kub ceev nrog rau cov yas molten, ua rau muaj kev sib txhuam loj ntawm cov kab noj hniav. Yog hais tias cov khoom pwm tsis hnav tsis kam, cov kab noj hniav yuav ua rau hnav ntau dhau; Yog li ntawd, cov khoom siv rau cov pwm no yuav tsum muaj kev hnav zoo heev.
(2) High Corrosion Resistance
Ntau cov khoom siv yas ntxiv -xws li cov nplaim hluav taws kub hnyiab- thiab cov tshuaj lom neeg ntawm cov yas molten nws tus kheej tuaj yeem ua rau pwm kab noj hniav. Kev puas tsuaj yog qhov hnyav ntxiv thaum cov khoom siv yas yas muaj cov khoom siv abrasive los yog cov khoom siv ntxiv. Txhawm rau txo qhov no, nws raug nquahu kom siv corrosion-cov hlau tiv taus lossis siv cov plating nto (xws li chrome lossis npib tsib xee plating) rau pwm.
(3) Zoo thermal conductivity
Kev tswj pwm kub tswj tau zoo cuam tshuam rau qhov zoo ntawm cov khoom yas thaum lub sij hawm txhaj tshuaj molding, ib qho tseem ceeb tshwj xeeb tshaj yog thaum ua semi-crystalline thermoplastics. Thaum tooj liab alloys feem ntau muab cov thermal conductivity zoo dua piv rau cov hlau alloy, lawv muaj qis dua elastic moduli, hardness, thiab durability. Qhov qis thermal conductivity ntawm hlau tuaj yeem raug them los ntawm kev siv lub tshuab ua kom txias.
(4) Zoo Dimensional Stability
Thaum lub sijhawm txhaj tshuaj molding, pwm kab noj hniav kub tuaj yeem tshaj 300 degree. Xws li qhov kub thiab txias hloov pauv tuaj yeem ua rau muaj kev hloov pauv ntawm cov qauv hauv cov kab noj hniav, ua rau muaj qhov tsis txaus ntseeg hauv pwm thiab, yog li ntawd, cov khoom yas. Txhawm rau hais txog qhov no, cov cuab yeej steel (kub-kho tau steels) uas tau dhau los ua qhov tsim nyog tempering feem ntau xaiv. Thaum kev kho cua sov feem ntau yog ua haujlwm los txhim kho hardness thiab hnav tsis kam, nws yuav tsum tau tswj kom txo qis qhov hloov pauv hauv pwm; Hloov chaw, machinable pre-hardened steels- uas yuav tsum tsis muaj kev kho cua sov ntxiv tom qab machining- tuaj yeem siv tau. (5) Kev ua haujlwm zoo polishing
Cov phab ntsa sab hauv ntawm pwm kab noj hniav yuav tsum muaj qhov roughness tsawg heev kom ntseeg tau tias cov khoom yas ua tiav qhov siab -gloss tiav; Yog li ntawd, cov chaw no feem ntau undergo polishing. Txij li thaum lub smoother, ntau lub ntsej muag zoo dua, cov khoom pwm yuav tsum yooj yim polish thiab tsis muaj qhov tsis xws luag xws li impurities lossis porosity.
