Cov Khoom Siv Hluav Taws Xob rau Cov Khoom Siv Hluav Taws Xob: Cov khoom siv lub cev muaj zog yog qhov nyuaj dua li lo lus yooj yim "yas" qhia! Kev xaiv cov khoom siv yuav tsum tau ua kom haum rau lub cev muaj zog qhov chaw ua haujlwm tshwj xeeb- suav nrog cov yam ntxwv xws li kub kub, roj tsis kam, thiab kev cuam tshuam. Cov ntaub ntawv yas uas siv rau hauv lub cev muaj xws li: * PBT (Polybutylene Terephthalate): Paub txog nws cov cua sov ua haujlwm thiab cov khoom siv hluav taws xob zoo heev, nws nquag siv rau cov khoom xws li lub kaus mom kawg thiab lub thawv davhlau ya nyob twg- ua haujlwm zoo li "lub tsho sov" rau lub cev muaj zog. * PA66 (Nylon 66): Cov yam ntxwv los ntawm lub zog siab thiab hnav tsis kam, nws yog qhov zoo tagnrho rau cov khoom sib kis xws li lub zog thiab cov kabmob, ua kom lub cev muaj zog ua haujlwm ruaj khov thiab du. * PPO (Polyphenylene Oxide): Lub npe nrov rau nws cov tshuaj tiv thaiv thiab qhov ruaj khov, feem ntau yog siv rau lub cev muaj zog- ua raws li kev tiv thaiv "cov ntaub thaiv npog" rau lub cev muaj zog sab hauv.
Qhov "High-Tech" ntawm Composite Materials: Puas yog ib qho khoom siv tsis txaus? Tom qab ntawd cia peb sim "sib xyaw"! Niaj hnub nimno lub cev muaj zog yas feem ntau siv cov ntaub ntawv sib xyaw los txhim kho kev ua tau zoo: * Iav Fiber Reinforcement: Los ntawm kev sib xyaw cov iav fibers rau hauv PBT lossis PA66 matrices, ob qho tib si lub zog thiab kub ua haujlwm tau txhawb nqa ntau heev -zoo li ntxiv "steel rebar" rau cov qauv yas. * Mineral Filling: Kev sib ntxiv ntawm cov zaub mov-xws li talc hmoov lossis calcium carbonate- pab txhim kho kev tswj cov shrinkage thiab gloss nto, ua rau lub cev muaj zog cov vaj tse uas smoother thiab zoo ib yam. * Kev hloov pauv nplaim hluav taws: Los ntawm kev ntxiv cov nplaim hluav taws, cov yas yuav tsis tshua muaj kev cuam tshuam rau kev sib tsoo hauv qhov kub siab -, yog li ua kom lub cev muaj zog tag nrho cov kev nyab xeeb- zoo ib yam li muab cov yas nrog ib qho ua tau -hauv "tshuaj tua hluav taws."
Lub tswv yim kos duab ntawm kev xaiv cov khoom: Xaiv cov yas zoo rau lub cev muaj zog tsis yog qhov kev txiav txim siab zoo! Cov kws ua haujlwm ua tib zoo ntsuas qhov sib xyaw ua ke ntawm cov yam ntxwv: * Ib puag ncig kev ua haujlwm: PBT raug xaiv rau siab - qhov kub thiab txias; PA66 rau cov av noo; thiab PPO rau kev teeb tsa corrosive. * Cov Nqi Them Nqi: General- cov hom phiaj plastics feem ntau yog siv rau cov qauv motors, thaum siab -kev ua tau zoo engineering plastics tau tshwj tseg rau cov qauv hwm- tawm tsam qhov sib npaug ntawm kev ua tau zoo thiab tus nqi- ua tau zoo. * Txoj Kev Ua: Cov txheej txheem tsim khoom sib txawv-xws li kev txhaj tshuaj molding, extrusion, lossis tuag casting- ua kom muaj kev sib txawv ntawm cov yas ntws thiab cov nqi shrinkage; yog li ntawd, cov khoom xaiv yuav tsum yog "tsim raws li cov ntawv thov tshwj xeeb." Piv txwv li, yog hais tias ib tug me me lub cev muaj zog yuav tsum tau ua hauj lwm rau kub mus txog 150 degree, ib tug engineer yuav xaiv PBT composite reinforced nrog 30% iav fiber ntau - ib qho kev xaiv uas ua kom muaj kev ruaj ntseg thaum tshav kub kub nyob rau tib lub sij hawm tswj tus nqi.
