Taw qhia
PMMA thiab acrylic yog ob lo lus uas feem ntau siv sib hloov, tab sis muaj qee qhov tsis meej pem txog seb lawv puas yog tib yam. Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv thiab zoo sib xws ntawm PMMA thiab acrylic.
PMMA yog dab tsi?
PMMA stands rau polymethyl methacrylate, uas tseem hu ua acrylic iav los yog acrylic. Nws yog cov pob tshab thermoplastic uas feem ntau siv rau ntau yam kev siv, xws li lub qhov rais tsheb, thoob dej yug ntses, thiab teeb pom kev zoo. PMMA yog cov khoom siv ntau yam uas tuaj yeem ua tau yooj yim zoo li tus thiab molded rau hauv ntau hom, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau ntau cov khoom lag luam thiab cov neeg siv khoom.
Acrylic yog dab tsi?
Acrylic yog ib lo lus uas siv los xa mus rau ntau yam sib txawv ntawm cov polymers uas tau muab los ntawm acrylic acid. Acrylics yog siv nyob rau hauv ntau yam kev siv, los ntawm cov xim thiab coatings rau plastics thiab textiles. Hom acrylic feem ntau yog polymethyl methacrylate, uas feem ntau hu ua PMMA.
Puas yog PMMA thiab acrylic tib yam?
Hauv ntej, yog, PMMA thiab acrylic yog qhov tseem ceeb tib yam. PMMA yog hom acrylic, tab sis muaj lwm hom acrylics uas tsis yog PMMA. Piv txwv li, muaj cov xim acrylic, uas yog tsim los ntawm kev sib xyaw ntawm acrylic polymers thiab pigments. Kuj tseem muaj acrylic textiles, uas yog tsim los ntawm kev sib xyaw ntawm acrylic fibers thiab lwm yam ntaub ntawv.
Dab tsi yog qhov zoo sib xws ntawm PMMA thiab acrylic?
Muaj ntau qhov sib xws ntawm PMMA thiab acrylic, suav nrog:
- Pob tshab: Ob leeg PMMA thiab acrylic yog cov ntaub ntawv pob tshab, ua rau lawv zoo tagnrho rau siv hauv cov ntawv thov uas qhov pom kev tseem ceeb.
- Durability: Ob qho khoom siv tau zoo heev thiab tiv taus kev puas tsuaj los ntawm ya raws, tshuaj, thiab kub heev.
- Versatility: Ob qho khoom siv tau yooj yim zoo li thiab molded rau hauv ntau hom, ua rau lawv zoo tagnrho rau ntau yam kev siv.
Dab tsi yog qhov txawv ntawm PMMA thiab acrylic?
Muaj qee qhov sib txawv ntawm PMMA thiab acrylic uas tsim nyog sau cia. Cov no suav nrog:
- Muaj pes tsawg leeg: PMMA yog ib hom acrylic uas tau muab los ntawm methyl methacrylate, thaum lwm hom acrylics yuav muab tau los ntawm cov tshuaj sib txawv.
- Cov txheej txheem ntau lawm: PMMA feem ntau yog tsim los ntawm cov txheej txheem hu ua bulk polymerization, thaum lwm hom acrylics yuav raug tsim los ntawm ntau txoj kev.
- Cov Khoom: Txawm tias PMMA thiab acrylic sib koom ntau yam khoom, tej zaum yuav muaj qhov sib txawv me ntsis ntawm lawv cov yam ntxwv ua haujlwm nyob ntawm seb hom acrylic tshwj xeeb.
Kev siv PMMA thiab acrylic
Ob leeg PMMA thiab acrylic muaj ntau yam kev siv thoob plaws ntau yam kev lag luam. PMMA feem ntau siv hauv:
- Skyscraper windows thiab canopies
- Teeb pom kev zoo thiab LED zaub
- Automotive qhov chaw, nrog rau qhov rais thiab lo ntsiab muag
- Acrylic rau tes thiab lwm yam khoom zoo nkauj
- Kos npe thiab taw qhia ntawm kev muag khoom
Acrylic, ntawm qhov tod tes, yog siv ntau yam khoom sib txawv thiab kev siv. Qee qhov kev siv rau acrylic muaj xws li:
- Xim thiab coatings
- Textiles thiab khaub ncaws
- Rooj tog thiab tsev kho kom zoo nkauj
- Aircraft canopies thiab windshields
- Kev kho mob cog thiab khoom siv
Xaus
Hauv kev xaus, PMMA thiab acrylic yog qhov tseem ceeb tib yam, vim PMMA yog hom acrylic. Txawm hais tias yuav muaj qhov sib txawv me ntsis ntawm ntau hom acrylics, muaj ntau qhov sib xws ntawm PMMA thiab acrylic, nrog rau lawv cov pob tshab, durability, thiab versatility. Ob leeg cov ntaub ntawv muaj ntau yam kev siv thoob plaws ntau yam kev lag luam thiab yog ib feem tseem ceeb ntawm kev tsim khoom niaj hnub thiab cov txheej txheem ntau lawm.
