Munguva pfupi yapfuura, tiri kugamuchira mibvunzo yakawanda pamusoro pekuti totsiva here chidziviriro chavo chekare cheacrylic nechidziviriro chegirazi chakapfava.
Ngatitaurei kuti chii chinonzi tempered glass uye PMMA kutanga sechikamu chipfupi:
Chii chinonzi girazi rinodziya?
Girazi rinodziyaimhando yegirazi rekuchengetedza rinogadziriswa nekurapwa kwekupisa kana kemikari kunodzorwa kuti riwedzere simba raro kana tichienzanisa negirazi remazuva ese.
Kudziisa kunoita kuti nzvimbo dzekunze dzive dzakamanikana uye mukati muve nepfungwa dzakasimba.
Inopwanyika kuita zvidimbu zvidiki zvegranular panzvimbo pezvidimbu zvakapinza sezvinoita girazi rekare rakaputirwa pasina kukuvara kwevanhu.
Inonyanya kushanda muzvigadzirwa zvemagetsi zve3C, zvivakwa, mota, nedzimwe nzvimbo dzakawanda.
Chii chinonzi PMMA?
Polymethyl methacrylate (PMMA), resin yakagadzirwa inogadzirwa kubva mukuumbwa kwemethyl methacrylate.
Purasitiki inoonekera uye yakaoma,PMMAinowanzoshandiswa panzvimbo pegirazi muzvigadzirwa zvakaita semahwindo asingaputsiki, magirazi epadenga, zviratidzo zvine chiedza, uye madenga endege.
Inotengeswa pasi pezviratidzo zvekutengeseranaPlexiglas, Lucite, uye Perspex.
Zvikurukuru zvakasiyana muzvinhu zvinotevera:
| Misiyano | Girazi rine 1.1mm | 1mm PMMA |
| Kuoma kwaMoh | ≥7H | Standard 2H, mushure mekusimbiswa ≥4H |
| Kutumira | 87~90% | ≥91% |
| Kugara kwenguva refu | Pasina kukwegura uye ruvara rwenhema mushure memakore | Kuchembera zviri nyore uye yero |
| Inodzivirira kupisa | Inogona kutsungirira tembiricha yepamusoro ye280°C isina kutyoka | PMMA inotanga kunyorova kana tembiricha yasvika 80°C |
| Basa rekubata | Inogona kuona basa rekubata & rekudzivirira | Ingova nebasa rekudzivirira chete |
Zviri pamusoro apa zvinoratidza pachena zvakanakira kushandisachidziviriro chegiraziZviri nani pane kudzivirira PMMA, ndinotarisira kuti zvichabatsira kuita sarudzo munguva pfupi.
