Posachedwa, tikulandila mafunso ambiri pankhani yokhuza kuteteza ma acrylic ndi oteteza galasi.
Tiyeni tikambirane kapu ndi pmma yoyamba ngati gulu lachidule:
Kodi kapu yolimba ndi chiyani?
GAWO LOKHAndi mtundu wagalasi yachitetezo chokonzedwa ndi mankhwala owombera mafuta kapena mankhwala kuti muwonjezere mphamvu yake poyerekeza ndi galasi labwinobwino.
Kupukutira kumayika malo akunja kukhala kukakamiza komanso mkati mwa kukangana.
Imasokoneza m'makola ang'onoang'ono m'malo mwa shards shards ngati galasi wamba lokhala ndi vuto la anthu osavulala.
Zimagwira ntchito makamaka mu 3c zamagetsi, nyumba, magalimoto, ndi madera ena ambiri.
PMMA ndi chiyani?
Polymethyl Metacrylate (Pmma), zopanga zopangidwa kuchokera ku polymerization wa methyl methacrytete.
Pulasitiki wowonekera komanso wokhazikika,PmmaNthawi zambiri amagwiritsidwa ntchito ngati choloweza mmalo mwa galasi pazinthu monga mawindo a shatterproof, chiwonetsero, zizindikiro, ndi zikwangwani za ndege.
Amagulitsidwa pansi pa zizindikiroKupembedza, Lucite, ndi Perpex.
Amakhala osiyanasiyana pazinthu zomwe zili pansipa:
| Kusiyana | 1.1mgalasi | 1mm PMMA |
| Kuumitsa kwa Moh | ≥7h | Muyezo 2h unalimbikitsa ≥4H |
| Kulunjika | 87 ~ 90% | ≥91% |
| Kulimba | Popanda ukalamba & utoto pambuyo pazaka | Zosavuta kupeza ukalamba & chikasu |
| Kutentha | Imatha kubereka 280 ° Chter Stenther osasweka | PMMA imayamba kufewetsa pamene 80 ° C |
| Kukhudza Ntchito | Ikhoza kuzindikira kukhudza & ntchito yoteteza | Khalani ndi ntchito yoteteza |
Zomwe zili pamwambapa zikuwonetsa bwino mwayi wogwiritsa ntchito aMtetezi WagalasiBwino kuposa PMMMA MPHALAMWE, ndikuyembekeza kuti ingathandize kupanga chisankho posachedwa.
