Cov khoom siv raw rau cov khoom txuas feem ntau yog cov yas thiab hlau.
Cov ntaub ntawv yas:
PBT (Polybutylene Terephthalate): Feem ntau siv rau hauv cov khoom sib txuas, nws muaj kev ua haujlwm tawg, kev cuam tshuam tsis zoo, hluav taws xob zoo, hnav tsis kam, tsis tshua muaj coefficient ntawm kev sib txhuam, tus kheej -lubricating zoo, thiab tsis kam rau roj thiab tshuaj. Nws muaj qhov shrinkage ntawm 0.6% -3.0%, qhov kub thiab txias ntawm ib ncig ntawm 230 degree, thiab nthuav tawm cov pwm zoo thiab nplaim hluav taws.
Nylon (piv txwv li, Nylon 66, Nylon 6T): Paub txog qhov zoo toughness, nws tus kheej-lubrication, tshuaj tiv thaiv, thiab hnav tsis kam. Nylon 6T muaj zog dua piv rau Nylon 66 thiab haum rau SMT connectors.
ABS: Nws muaj cov yam ntxwv zoo ntawm kev sib zog, roj thiab hnav tsis kam, yooj yim ntawm molding, thiab rigidity. Nrog rau qhov kub thiab txias ntawm ib puag ncig 100 degree, nws feem ntau yog siv rau cov khoom siv txuas ntxiv.
PC (Polycarbonate) thiab LCP (Liquid Crystal Polymer): Cov ntaub ntawv no muaj cov khoom siv hluav taws xob zoo heev thiab ua kom sov, ua kom muaj hluav taws xob ruaj khov ntawm qhov kub thiab txias, nrog rau kev ua haujlwm zoo corrosion thiab thermal stability.
Cov khoom siv hlau:
Kev xaiv cov ntaub ntawv hlau feem ntau yog raws li cov yam ntxwv xws li lub zog tawm los, lub zog tensile, elongation, hardness, thiab R / T piv. Cov kev ntsuas no yog qhov tseem ceeb rau kev sib txuas tsim thiab xaiv cov khoom siv; tshwj xeeb, thaum yuav tsum tau miniaturization, xaiv cov ntaub ntawv nrog kev ua haujlwm zoo heev yog qhov tseem ceeb tshwj xeeb.
Kev xaiv cov khoom nyob ntawm qhov tshwj xeeb daim ntawv thov ntawm lub connector; Piv txwv li, automotive connectors tej zaum yuav tsum tau superior kub kuj, whereas connectors rau cov qauv hluav taws xob tej zaum yuav precisely tus nqi -effectiveness thiab yooj yim ntawm molding.
