Kodi Mbiri ya Chitukuko cha Acrylic ndi Chiyani?

Monga momwe tonse timadziwira, acrylic imatchedwanso plexiglass yokonzedwa mwapadera. Galasi la acrylic ndi thermoplastic yowonekera bwino yomwe ndi yopepuka komanso yosasweka, zomwe zimapangitsa kuti ikhale njira ina yokongola m'malo mwa galasi. Mitundu ya magalasi opangidwa ndi anthu idayamba mu 3500 BC, ndipo kafukufuku ndi chitukuko cha acrylic chili ndi mbiri ya zaka zoposa zana.

Mu 1872, polymerization ya acrylic acid idapezeka.

Mu 1880, polymerization ya methyl acrylic acid idadziwika.

Mu 1901, kafukufuku wa kapangidwe ka propylene polypropionate unamalizidwa.

Mu 1907, Dr. Röhm anatsimikiza mtima kukulitsa kafukufuku wake wa udokotala mu acrylic acid ester polymerisate, chinthu chopanda utoto komanso chowonekera, komanso momwe chingagwiritsidwire ntchito m'malonda.

Mu 1928, kampani ya mankhwala ya Röhm ndi Haas inagwiritsa ntchito zomwe adapeza popanga Luglas, yomwe inali galasi lotetezera lomwe limagwiritsidwa ntchito popanga mawindo a magalimoto.

Dr. Röhm sanali yekhayo amene ankaganizira kwambiri za magalasi oteteza - kumayambiriro kwa zaka za m'ma 1930, akatswiri a zamankhwala aku Britain ku Imperial Chemical Industries (ICI) adapeza polymethyl methacrylate (PMMA), yomwe imadziwikanso kuti galasi la acrylic. Iwo adalemba chizindikiro cha zomwe adapeza acrylic kuti Perspex.

Ofufuza a Röhm ndi Haas adatsatira kwambiri; posakhalitsa adapeza kuti PMMA ikhoza kusinthidwa kukhala polymer pakati pa mapepala awiri agalasi ndikulekanitsidwa ngati pepala lake lagalasi la acrylic. Röhm adagulitsa izi ngati Plexiglass mu 1933. Pa nthawiyi, EI du Pont de Nemours & Company yobadwira ku United States (yomwe imadziwikanso kuti DuPont) idapanganso mtundu wawo wagalasi la acrylic pansi pa dzina la Lucite.

Pa Nkhondo Yachiwiri Yapadziko Lonse, ndi mphamvu yabwino kwambiri, kulimba komanso kufalikira kwa kuwala, acrylic idayikidwa koyamba pagalasi lakutsogolo la ndege ndi galasi la akasinja.

Pamene Nkhondo Yachiwiri Yapadziko Lonse inali kutha, makampani omwe ankapanga ma acrylic anakumana ndi vuto latsopano: kodi akanapanga chiyani pambuyo pake? Kugwiritsa ntchito magalasi a acrylic m'mabizinesi kunayamba kuonekera kumapeto kwa zaka za m'ma 1930 ndi kumayambiriro kwa zaka za m'ma 1940. Makhalidwe osagwedezeka komanso osasweka omwe adapangitsa kuti acrylic ikhale yabwino kwambiri pamagalasi akunja ndi mawindo tsopano akukula kukhala ma visor a chisoti, magalasi akunja pamagalimoto, zida za apolisi zodzitchinjiriza, malo osungiramo madzi, komanso "galasi" lozungulira malo ochitira hockey. Ma acrylic amapezekanso mu mankhwala amakono, kuphatikizapo zolimba, zosinthira ma cataract, ndi zoyikamo. Nyumba yanu mwina imadzaza ndi magalasi a acrylic: zowonetsera za LCD, magalasi osasweka, mafelemu azithunzi, zikho, zokongoletsa, zoseweretsa, ndi mipando nthawi zambiri zimapangidwa ndi magalasi a acrylic.

Kuyambira pomwe idapangidwa, galasi la acrylic ladziwonetsa lokha kukhala chisankho chotsika mtengo komanso cholimba pa ntchito zambiri.

Kwa zaka zoposa 20, DHUA yakhala ikupanga zinthu zotsogola zopangira ma acrylic sheet ndi ma acrylic glass sheet. Malingaliro a bizinesi a DHUA akhalabe ogwirizana kwambiri - amapereka zinthu zapamwamba kwambiri padziko lonse lapansi kwa makasitomala apamwamba. Lumikizanani ndi DHUA lero kuti mudziwe zambiri za zinthu zawo za acrylic, ukadaulo wopanga, ndi ntchito zomwe zakonzedwa kuti zigwirizane ndi zosowa zanu za acrylic.
