Vuba aha, twakiriye ibibazo byinshi bijyanye no kumenya niba twasimbuza irinda rya kera rya acrylic irinda ikirahure.
Reka tuvuge icyo ikirahure gishyushye na PMMA ari cyo mbere na mbere mu gushyira mu byiciro muri make:
Ikirahure gishyushye ni iki?
Ikirahure gishyushyeni ubwoko bw'ikirahure cy'umutekano gitunganywa hakoreshejwe uburyo bukoreshwa mu kuvura ubushyuhe cyangwa imiti kugira ngo cyongere imbaraga zacyo ugereranije n'ikirahure gisanzwe.
Gushyushya bishyira ubuso bwo hanze mu gitutu n'imbere mu gitutu.
Imenekamo uduce duto tw’uduce aho kuba uduce duto nk’uko ikirahure gisanzwe kibikora nta ngaruka mbi ku bantu.
Bikoreshwa cyane cyane mu bikoresho by'ikoranabuhanga bya 3C, inyubako, imodoka, n'ahandi henshi.
PMMA ni iki?
Polymethyl methacrylate (PMMA), resin y’ubukorikori ikorwa binyuze mu gupolima kwa methacrylate ya methyl.
Plasitike ibonerana kandi ikomeye,PMMAikunze gukoreshwa nk'ikintu gisimbura ikirahuri mu bikoresho nk'amadirishya adacika, amatara yo hejuru, ibimenyetso bimurikwa, n'ibisenge by'indege.
Igurishwa munsi y'ibirango by'ubucuruziPlexiglas, Lucite, na Perspex.
Bitandukanye cyane cyane muri ibi bikurikira:
| Itandukaniro | Ikirahure cyuzuyemo umwuka cya 1.1mm | 1mm PMMA |
| Ubukomere bwa Moh | ≥7H | 2H isanzwe, nyuma yo gukomezwa ≥4H |
| Kohereza | 87 ~ 90% | ≥91% |
| Kuramba | Nta gusaza no gusibanganya ibara nyuma y'imyaka myinshi | Gusaza byoroshye no kugira umuhondo |
| Irwanya ubushyuhe | Ishobora kwihanganira ubushyuhe bwinshi bwa 280°C idacitse | PMMA itangira koroha iyo ubushyuhe buri hejuru ya 80°C |
| Imikorere yo gukoraho | Ishobora gukora ku gukoraho no kurinda | Kugira imikorere yo kurinda gusa |
Ibivuzwe haruguru bigaragaza neza inyungu zo gukoreshaurinda ikirahurekurusha PMMA, nizeye ko bizagufasha gufata icyemezo vuba.
