Qhov sib txawv tseem ceeb ntawm cov khoom siv yas thiab cov yas engineering yog tias cov khoom siv yas muaj cov khoom siv hluav taws xob zoo dua thiab cov khoom siv thermal zoo dua li cov khoom yas.
Cov khoom yas yog cov khoom siv polymer uas siv thaum tsis tas yuav muaj cov khoom tshwj xeeb. Engineering plastics yog ib hom yas uas muaj cov khoom siv zoo dua qub thiab thermal zoo dua piv rau cov khoom siv yas. Tsis tas li ntawd, cov khoom siv yas tsis tshua kim, qhov kev tsim khoom yas yog cov khoom kim heev.
Cov Khoom Siv Plastics yog dab tsi?
Cov khoom yas yog cov khoom siv polymer uas siv thaum tsis tas yuav muaj cov khoom tshwj xeeb. Cov no tseem muaj npe cov khoom siv polymers. Lawv daim ntawv thov feem ntau suav nrog kev ntim khoom, ntim khoom noj khoom haus, thiab kev tsim khoom hauv tsev. Hom khoom no pheej yig los tsim. Tsis tas li ntawd, lawv nthuav tawm cov khoom ua haujlwm tsis muaj zog. Cov piv txwv feem ntau rau cov khoom siv yas xws li polyethylene, polypropylene, polystyrene, polyvinyl chloride, thiab poly (methyl methacrylate).
Daim duab 01: Kev thov rau cov yas hauv Tebchaws Europe xyoo 2017
hom yas no muaj txiaj ntsig zoo hauv kev tsim cov ntawv pov tseg, khob pov tseg, thaij duab thiab sib nqus daim kab xev, khaub ncaws, hnab rov siv tau, cov tais kho mob, thiab cov tais ntim khoom. Feem ntau, cov yas yog cov khoom hnyav molecular siab, yog li cov khoom siv hluav taws xob tuaj yeem ua rau muaj kev pheej hmoo vim hluav taws kub sib cuam tshuam nrog huab hwm coj thiab kev thauj mus los ntawm lub zog tuaj yeem ua rau muaj teeb meem.
Dab tsi yog Engineering Plastics?
Engineering plastics yog ib hom yas uas muaj cov khoom siv zoo dua qub thiab thermal zoo dua piv rau cov khoom siv yas. Tsis tas li ntawd, cov khoom siv no kim dua cov khoom siv yas. Vim li no, engineering plastics yog tsim los ntawm cov khoom tsawg. Tsis tas li ntawd, hom yas no muaj txiaj ntsig zoo rau cov khoom me me lossis cov ntawv ntim tsawg. Yog li ntawd, engineering plastics yog qhov tseem ceeb hauv kev tsim khoom siv tshuab ntau dua li kev ntim khoom lossis kev tsim cov thawv.
Daim duab 02: Siv Cov Khoom Siv Hluav Taws Xob
Feem ntau, lo lus engineering yas yog siv rau cov ntaub ntawv thermoplastic tshaj cov khoom siv thermosetting. Qee qhov piv txwv zoo tshaj plaws rau cov yas yas xws li acrylonitrile butadiene styrene, uas muaj txiaj ntsig zoo rau lub tsheb bumpers, dashboard trim thiab Lego cib, polycarbonates uas muaj txiaj ntsig zoo hauv kev tsim cov kaus mom hlau maus taus thiab optical discs, polyamides pab tau rau kev caij ski thiab khau boots, thiab lwm yam.
Cov yas no muaj cov khoom tshwj xeeb: muaj kev cuam tshuam siab ntawm polycarbonates, siab tiv thaiv kev puas tsuaj los ntawm polyamides, lwm yam khoom siv hluav taws xob qhia cov cua sov ua haujlwm, txhua yam muaj zog, rigidity, tshuaj stability, nws tus kheej lubrication, thiab lwm yam.
Qhov txawv ntawm Cov Khoom Siv Yas thiab Cov Khoom Siv Hluav Taws Xob yog dab tsi?
Cov khoom yas yog cov khoom siv polymer uas siv thaum tsis tas yuav muaj cov khoom tshwj xeeb. Engineering plastics yog ib hom yas uas muaj cov khoom siv zoo dua qub thiab thermal zoo dua piv rau cov khoom siv yas. Qhov sib txawv tseem ceeb ntawm cov khoom siv plastics thiab engineering plastics yog tias engineering plastics qhia tshwj xeeb txhua yam thiab thermal zog piv rau cov khoom yas. Tsis tas li ntawd, cov khoom siv plastics tsis tshua kim, thaum engineering plastics yog cov khoom kim heev. Qee qhov piv txwv ntawm cov khoom yas xws li polyethylene, polypropylene, polystyrene, polyvinyl chloride, thiab poly (methyl methacrylate), thaum piv txwv ntawm engineering plastics suav nrog acrylonitrile butadiene styrene, polycarbonates, polyamides, thiab lwm yam.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov khoom siv plastics thiab engineering plastics hauv kev nthuav dav ntxiv, hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Khoom Plastics vs Engineering Plastics
Cov khoom yas yog cov khoom siv polymer uas siv thaum tsis tas yuav muaj cov khoom tshwj xeeb. Engineering plastics yog ib hom yas uas muaj cov khoom siv zoo dua qub thiab thermal zoo dua piv rau cov khoom siv yas. Qhov sib txawv tseem ceeb ntawm cov khoom siv plastics thiab engineering plastics yog tias engineering plastics qhia tshwj xeeb txhua yam thiab thermal zog piv rau cov khoom yas. Tsis tas li ntawd, cov khoom siv yas tsis tshua muaj nqi, qhov khoom siv yas yog cov khoom kim heev.
