Ua ntej ntawm tag nrho cov, dab tsi yog yas
1) Cov khoom siv yas (kev muag khoom ntawm LC yas raw cov ntaub ntawv, cov khoom siv kub kub resistant, PPS, LCP, PET, PA, PES cov khoom siv raw khoom): cov khoom tseem ceeb yog cob, uas yog tsim los ntawm cov khoom siv hluavtaws ua lub ntsiab tivthaiv thiab nkag mus rau hauv ntau yam khoom siv Cov khoom siv los yog cov khoom siv ntxiv, uas muaj cov yas thiab kev txav mus los ntawm qhov kub thiab txias, tuaj yeem ua pwm rau hauv ib qho duab, thiab tseem yog cov khoom siv uas tsis hloov cov duab hauv qee yam kev mob;
2) Yas muaj cov khoom zoo rwb thaiv tsev rau hluav taws xob, cua sov thiab suab: hluav taws xob rwb thaiv tsev, arc tsis kam, txuag hluav taws xob, suab rwb thaiv tsev, suab nqus, kev co, thiab suab ntsiag to kev ua haujlwm.
3) Feem ntau ntawm cov khoom siv yas yog muab rho tawm los ntawm qee cov roj.Qhov feem ntau paub txog cov khoom siv PC (polycarbonate yas) yog muab rho tawm los ntawm cov roj av.
Cov khoom siv PC muaj roj tsw qab thaum nws hlawv;ABS (acrylonitrile-butadiene-styrene copolymer yas) yog muab rho tawm los ntawm cov thee,
ABS yuav nyob rau hauv daim ntawv ntawm soot thaum nws hlawv tawm;POM (polyoxymethylene yas) yog muab rho tawm los ntawm natural gas,
POM muaj ntxhiab tsw ntxhiab tsw heev thaum nws hlawv.
Cov yam ntxwv ntawm cov khoom siv yas dav dav (LC yas raw khoom lag luam wholesale, siab kub resistant yas ntaub ntawv, PPS, LCP, PET, PA, PES yas raw khoom lwm tus neeg):
1) Cov khoom siv yas yog compressed los ntawm tshav kub, thiab cov coefficient ntawm linear expansion yog loj dua li ntawm cov hlau;
2) Qhov nruj ntawm cov ntaub ntawv yas dav dav yog qhov kev txiav txim siab qis dua li cov hlau;
3) Cov khoom siv hluav taws xob ntawm cov khoom siv yas yuav raug txo kom tsawg hauv cov cua sov ntev;
4) Feem ntau, cov khoom siv yas yog ib ntus kev ntxhov siab nyob rau hauv chav tsev kub thiab nyob rau hauv ib qho kev ntxhov siab qis dua nws lub zog yield, thiab deformation mus tas li yuav tshwm sim;
5) Kev muag khoom ntawm cov ntaub ntawv yas raw khoom yog rhiab heev rau kev puas tsuaj;
6) Cov khoom siv hluav taws xob ntawm cov khoom siv yas yog feem ntau qis dua cov hlau, tab sis lub zog tshwj xeeb thiab cov qauv tshwj xeeb ntawm qee cov ntaub ntawv sib xyaw yog siab dua cov hlau.Yog tias cov khoom tsim tsim nyog, nws yuav muaj txiaj ntsig zoo dua;
7) Feem ntau, cov khoom siv ntawm cov khoom siv yas muaj zog yog anisotropic;
8) Qee cov ntaub ntawv yas yuav nqus dej noo thiab ua rau muaj kev hloov pauv loj thiab kev ua haujlwm;
9) Qee cov yas yog cov nplaim taws.
Yas raw khoom faib (LC yas raw khoom lag luam wholesale, kub resistant yas khoom, PPS, LCP, PET, PA, PES yas raw khoom tsum)
Cov khoom siv yas ua raws li cov qauv molecular ntawm cov khoom siv hluavtaws thiab feem ntau muab faib ua cov thermoplastic thiab thermosetting plastics: thermoplastic plastics xa mus rau cov yas uas tseem yas tom qab rov ua cua sov: feem ntau PE÷PP÷PVC÷PS÷ABS÷PMMA÷POM÷PC÷ PA thiab lwm yam khoom siv raw.Thermosetting plastics feem ntau yog xa mus rau cov yas ua los ntawm cov khoom siv hluav taws xob uas muaj cua sov, xws li qee cov phenolic plastics thiab amino plastics, uas tsis yog siv ntau.
Raws li qhov kev thov, muaj cov khoom siv dav dav xws li PE÷PP÷PVC÷PS, thiab lwm yam, thiab cov khoom siv hluav taws xob xws li ABS÷POM÷PC÷PA thiab lwm hom kev siv.Tsis tas li ntawd, muaj qee cov yas tshwj xeeb xws li qhov kub thiab txias, cov av noo thiab corrosion kuj thiab lwm yam yas hloov kho rau lub hom phiaj tshwj xeeb.
Tam sim no koj yuav tsum paub meej, yas tsis yog yas, tab sis nws cov khoom tseem ceeb yog cob, thiab cov khoom tseem ceeb ntawm cov yas kuj yog cob.Ob leeg tsuas yog tib lub ntsiab tseem ceeb xwb, tsis yog tib yam.
