Tsis ntev los no, peb tau txais ntau cov lus nug txog seb puas yuav hloov lawv cov acrylic protector qub nrog cov iav tempered protector.
Cia peb hais txog dab tsi yog tempered iav thiab PMMA ua ntej ua ib qho kev faib tawm luv luv:
Iav tempered yog dab tsi?
iav kubyog ib hom iav kev nyab xeeb uas ua los ntawm kev tswj hwm thermal lossis tshuaj lom neeg kom ua rau nws lub zog ntau dua li cov iav ib txwm muaj.
Tempering ua rau cov nplaim sab nraud nruj thiab sab hauv nruj.
Nws tawg ua tej daim me me es tsis txhob ua tej daim me me zoo li cov iav annealed ib txwm ua tsis muaj kev raug mob rau tib neeg.
Nws feem ntau siv rau hauv 3C cov khoom siv hluav taws xob, tsev, tsheb, thiab ntau lwm qhov chaw.
PMMA yog dab tsi?
Polymethyl methacrylate (polymethyl methacrylate)PMMA), cov khoom siv hluavtaws tsim los ntawm kev sib xyaw ua ke ntawm methyl methacrylate.
Ib lub yas pob tshab thiab tawv,PMMAfeem ntau siv los ua ib qho hloov iav hauv cov khoom xws li cov qhov rai tawg, lub ru tsev saum ru tsev, cov paib ci, thiab cov canopies dav hlau.
Nws raug muag raws li cov cim lag luamPlexiglas, Lucite, thiab Perspex.
Lawv feem ntau txawv ntawm cov hauv qab no:
| Qhov txawv | 1.1 hli Tempered Iav | 1 hli PMMA |
| Moh's Hardness | ≥7H | Tus qauv 2H, tom qab muaj zog ≥4H |
| Kev Sib Kis | 87~90% | ≥91% |
| Kev ruaj khov | Tsis muaj kev laus & xim cuav tawm tom qab ntau xyoo | Yooj yim tau laus & daj |
| Tiv taus cua sov | Muaj peev xwm dais 280 ° C kub siab yam tsis muaj tawg | PMMA pib mos thaum 80 ° C |
| Kov Muaj nuj nqi | Muaj peev xwm paub txog kev kov thiab kev tiv thaiv | Tsuas muaj lub luag haujlwm tiv thaiv xwb |
Qhov saum toj no qhia meej meej txog qhov zoo ntawm kev siv aiav tiv thaivzoo dua li tus neeg tiv thaiv PMMA, vam tias nws yuav pab txiav txim siab sai sai.
