Posachedwapa, tikulandira mafunso ambiri okhudza ngati tisinthe choteteza chawo chakale cha acrylic ndi choteteza galasi chofewa.
Tiyeni tinene kuti galasi lofewa ndi PMMA ndi chiyani choyamba monga gulu lalifupi:
Kodi galasi lofewa ndi chiyani?
Galasi lofewandi mtundu wa galasi lotetezeka lomwe limakonzedwa ndi mankhwala olamulidwa ndi kutentha kapena mankhwala kuti liwonjezere mphamvu yake poyerekeza ndi galasi wamba.
Kutenthetsa kumapangitsa kuti malo akunja akhale opanikizika ndipo mkati mwake mukhale opsinjika.
Imasweka m'zidutswa zazing'ono m'malo mwa zidutswa zosweka monga momwe galasi wamba lophimbidwa limachitira popanda kuvulaza anthu.
Imagwira ntchito makamaka pazinthu zamagetsi za 3C, nyumba, magalimoto, ndi madera ena ambiri.
Kodi PMMA ndi chiyani?
Polymethyl methacrylate (PMMA), utomoni wopangidwa kuchokera ku polymerization ya methyl methacrylate.
Pulasitiki yowonekera bwino komanso yolimba,PMMAnthawi zambiri amagwiritsidwa ntchito m'malo mwa galasi m'zinthu monga mawindo osasweka, ma skylights, zizindikiro zowala, ndi ma canopy a ndege.
Imagulitsidwa pansi pa zizindikiro za malondaPlexiglas, Lucite, ndi Perspex.
Amasiyana kwambiri m'mbali zotsatirazi:
| Kusiyana | Galasi Lolimba la 1.1mm | 1mm PMMA |
| Kuuma kwa Moh | ≥7H | Standard 2H, pambuyo polimbikitsidwa ≥4H |
| Kutumiza | 87~90% | ≥91% |
| Kulimba | Popanda ukalamba ndi utoto wabodza pambuyo pa zaka zambiri | Kukalamba mosavuta komanso chikasu |
| Wosatentha | Imatha kupirira kutentha kwakukulu kwa 280°C popanda kusweka | PMMA imayamba kufewa ikatentha madigiri 80 Celsius |
| Ntchito Yogwira | Imatha kugwira ntchito yoteteza komanso yokhudza kukhudza | Khalani ndi ntchito yoteteza yokha |
Zomwe zili pamwambapa zikuwonetsa bwino ubwino wogwiritsa ntchitochoteteza galasikuposa chitetezo cha PMMA, ndikuyembekeza kuti zithandiza kupanga chisankho posachedwa.
