Kuyamba kwa thermoplastic acrylic resin
Thermoplastic Acrylic Resins ndi gulu la ma resins a thermoplastic opangidwa ndi polymerizing acrylic acid, methacrylic acid ndi zotumphukira zake monga esters, nitriles, ndi amides.Ikhoza kuchepetsedwa mobwerezabwereza ndi kutentha ndi kulimba ndi kuzizira.Nthawi zambiri, ndi mzere wa polima, womwe ukhoza ...Werengani zambiri -
Makhalidwe azinthu ndi kugwiritsa ntchito mapulasitiki a propylene
Polymethyl methacrylate, yotchedwa PMMA, yomwe imadziwika kuti plexiglass, yomwe imadziwikanso kuti acrylic.Ili ndi mawonekedwe olimba, osasweka, owoneka bwino, osagwirizana ndi nyengo, osavuta kuyika utoto komanso mawonekedwe, ndipo yakhala pulasitiki yowoneka bwino yomwe imagwiritsidwa ntchito kwambiri.Plexiglass ndiye njira yabwino kwambiri ...Werengani zambiri -
Mbiri ya Plexiglass
Mu 1927, katswiri wa zamankhwala ku kampani ya ku Germany anatenthetsa acrylate pakati pa mbale ziwiri zamagalasi, ndipo acrylate polymerized kuti apange interlayer yofanana ndi mphira wa viscous yomwe ingagwiritsidwe ntchito ngati galasi lotetezera kusweka.Akapanga polymerized methyl methacrylate mwanjira yomweyo, mbale ya plexiglass yokhala ndi ...Werengani zambiri -
Makhalidwe a Acrylic Lens
A. Kachulukidwe kakang'ono: chifukwa cha kusiyana pakati pa maunyolo a molekyulu, kuchuluka kwa mamolekyu pa voliyumu imodzi ndi yaying'ono, yomwe imatsimikizira ubwino wa lens ya utomoni: mphamvu yokoka yotsika komanso mawonekedwe opepuka, omwe ndi 1/3-1/2 ya lens galasi;B. Moderate refractive index: wamba CR-39 propylene diet...Werengani zambiri -
Chiyambi cha Magalasi a Acrylic
Lens ya utomoni ndi organic material.Mkati mwake muli mawonekedwe a unyolo wa polima, omwe amalumikizidwa kuti apange maukonde amitundu itatu.Mapangidwe a intermolecular ndi omasuka, ndipo pali danga pakati pa maunyolo a maselo omwe angapangitse kusamuka kwawo.The lig...Werengani zambiri
