Tsis ntev los no, peb tau txais ntau cov lus nug txog seb puas yuav hloov lawv cov qub acrylic tiv thaiv nrog tempered iav tiv thaiv.
Cia peb hais dab tsi yog tempered iav thiab PMMA ua ntej raws li kev qhia luv luv:
Tempered iav yog dab tsi?
Tempered iavyog ib hom kev nyab xeeb iav ua tiav los ntawm kev tswj cov thermal lossis tshuaj kho kom nws lub zog ntau dua piv nrog cov iav ib txwm muaj.
Tempering muab cov chaw sab nrauv rau hauv compression thiab sab hauv kom nruj.
Nws shatters rau hauv me me granular chunks es tsis txhob ntawm jagged shards li zoo tib yam annealed iav tsis muaj kev raug mob rau tib neeg.
Nws tsuas yog siv rau hauv 3C cov khoom siv hluav taws xob, cov tsev, tsheb, thiab ntau qhov chaw.
PMMA yog dab tsi?
Polymethyl methacrylate (PMMA), cov khoom siv hluavtaws ua los ntawm polymerization ntawm methyl methacrylate.
Plastic pob tshab thiab nruj,PMMAfeem ntau yog siv los hloov iav hauv cov khoom xws li shatterproof windows, skylights, illuminated kos npe, thiab aircraft canopies.
Nws yog muag raws li cov cim lag luamPlexiglas, Lucite, thiab Perspex.
Lawv feem ntau txawv ntawm cov hauv qab no:
| Qhov txawv | 1.1mm Tempered iav | 1 hli PMMA |
| Moh's Hardness | ≥7 H | Txheem 2H, tom qab muaj zog ≥4H |
| Kev xa tawm | 87-90% | ≥91% |
| Durability | Tsis muaj kev laus & xim cuav tawm tom qab xyoo | Yooj yim tau aging & yellowish |
| Thaum tshav kub kub Resistant | Muaj peev xwm dais 280 ° C siab kub tsis tawg | PMMA pib mos thaum 80 ° C |
| Kov muaj nuj nqi | Tau paub kov & tiv thaiv muaj nuj nqi | Tsuas muaj txoj haujlwm tiv thaiv |
Cov saum toj no qhia meej meej qhov zoo ntawm kev siv aiav tiv thaivzoo dua li tus tiv thaiv PMMA, vam tias nws yuav pab txiav txim siab sai sai.
