(1) High Wear Resistance
Txhawm rau ua kom cov rigidity thiab mechanical zog ntawm cov khoom yas, iav fiber ntau thiab inorganic fillers yog siv dav hauv cov qauv yas rau kev txhawb nqa. Tom qab cov additives no ntxiv, lawv nkag mus rau hauv pwm kab noj hniav ntawm kev kub ceev nrog rau cov khoom molten, ua rau muaj kev sib txhuam loj hauv pwm. Yog tias cov khoom pwm tsis hnav- tiv taus, kab noj hniav tau yooj yim raug hnav ntau dhau. Yog li ntawd, cov khoom siv los ua cov pwm zoo li no yuav tsum muaj kev hnav zoo tshwj xeeb.
(2) High Corrosion Resistance
Ntau cov khoom siv yas, xws li nplaim hluav taws, thiab txawm tias cov tshuaj lom neeg ntawm cov khoom molten nws tus kheej, tuaj yeem ua rau pwm kab noj hniav. Thaum cov khoom siv yas muaj cov khoom siv abrasive thiab cov khoom siv ntxiv, cov pwm puas tsuaj ntxiv. Yog li ntawd, nws yog qhov zoo tshaj plaws los siv corrosion-cov hlau tsis muaj zog lossis ua cov txheej txheem electroplating ntawm cov pwm, xws li chrome plating lossis npib tsib xee plating.
(3) Zoo thermal conductivity
Thaum lub sij hawm txhaj tshuaj molding, pwm zoo tswj qhov kub thiab txias muaj feem xyuam rau qhov zoo ntawm cov khoom yas, tshwj xeeb tshaj yog thaum ua semi-crystalline thermoplastics. Feem ntau, tooj liab alloys muaj thermal conductivity zoo dua li cov hlau alloy, tab sis lawv cov qauv elastic, hardness, thiab durability yog qis dua. Cov thermal conductivity tsis txaus ntawm cov hlau tuaj yeem raug them los ntawm lub tshuab cua txias.
(4) Zoo Dimensional Stability
Thaum lub sij hawm txhaj tshuaj molding, qhov kub ntawm cov pwm kab noj hniav nce mus txog 300 degree. Xws li qhov kub thiab txias sib txawv yooj yim ua rau microscopic hloov pauv hauv kab noj hniav, ua rau cov pwm hloov pauv thiab qhov tsis ruaj khov ntawm cov yas qhov ntev. Yog li ntawd, cov cuab yeej steel nrog kev kho kom zoo, piv txwv li, cua sov- kho steel, tuaj yeem xaiv. Txhawm rau txhim kho hardness thiab hnav tsis kam, pwm feem ntau raug kho cua sov. Txawm li cas los xij, qhov kev kho cua sov no yuav tsum muaj kev cuam tshuam tsawg kawg ntawm cov pwm qhov ntev. Ua ntej- cov hlau tawv tawv uas tuaj yeem siv tau; hom hlau no tsis xav tau kev kho cua sov tom qab machining.
(5) Kev ua haujlwm zoo polishing
Lub puab phab ntsa ntawm cov pwm kab noj hniav yuav tsum tau siab precision thiab tsis tshua muaj roughness kom tau raws li qhov yuav tsum tau ntawm zoo gloss nyob rau saum npoo ntawm cov yas. Yog li ntawd, cov pwm kab noj hniav feem ntau yuav tsum tau polished, thiab qhov ci ntsa iab, qhov zoo dua. Vim li no, cov khoom siv pwm yuav tsum yooj yim rau polish, thiab cov khoom xaiv yuav tsum tsis txhob muaj impurities lossis tsis xws luag xws li pores.
