Asidhi yeMethacrylic (2-Methyl-2-propenoic acid)
| Hunhu hwemakemikari | Asidhi yeMethacrylic, kana kuti MAA pfupiso, imusanganiswa weorganic. Mvura iyi isina ruvara, ine viscous, icarboxylic acid ine hwema husina kunaka. Inonyungudika mumvura inodziya uye inogona kusanganiswa nezvimwe zvinonyungudutsa zveorganic. Asidhi yeMethacrylic inogadzirwa mumaindasitiri zvakanyanya senzira yekutanga maesters ayo, kunyanya methyl methacrylate (MMA) uye poly(methyl methacrylate) (PMMA). Methacrylates ine mashandisirwo akawanda, kunyanya mukugadzira mapolymer ane mazita ekutengeserana akadai seLucite nePlexiglas. MAA inowanikwa muzvishoma mumafuta eRoman chamomile. | |
| Mashandisirwo | Methacrylic acid inoshandiswa mukugadzira methacrylate resins nemapurasitiki. Inoshandiswa seMonomer yemaresin nemapolymers makuru, organic synthesis. Mazhinji emapolymers akavakirwa pamaesters eacid, semethyl, butyl, kana isobutyl esters. Methacrylic acid nemaesters emethacrylate anoshandiswa kugadzira mapolymers akasiyana-siyana [→ Polyacrylamides nePoly(Acrylic Acids), → Polymethacrylates]. Poly(methyl methacrylate) ndiyo polymer huru muchikamu ichi, uye inopa mapurasitiki akajeka, akaomarara anoshandiswa muchimiro chepepa mugirazi, zviratidzo, zviratidziro, uye mapaneru emwenje. | |

Kuchengetedzeka
Pakubata chigadzirwa ichi, ndapota tevedzera mazano neruzivo rwuri mupepa rekuchengetedza uye tevera matanho ekudzivirira uye ehutsanana panzvimbo yebasa akakodzera pakubata makemikari.
Cherechedza
Ruzivo rwuri muchinyorwa chino rwakavakirwa paruzivo rwedu rwemazuva ano uye ruzivo. Tichifunga nezvezvinhu zvakawanda zvinogona kukanganisa kugadziriswa nekushandiswa kwechigadzirwa chedu, ruzivo urwu harurerutsi vagadziri vezvigadzirwa kubva pakuita ongororo dzavo uye bvunzo; uye ruzivo urwu harurevi vimbiso yezvimwe zvinhu, kana kukodzera kwechigadzirwa kune chinangwa chaicho. Chero tsananguro, mifananidzo, mapikicha, data, zviyero, huremu, nezvimwewo zvakapihwa pano zvinogona kuchinja pasina ruzivo rwekare uye hazvirevi mhando yechibvumirano chechigadzirwa. Hunhu hwechibvumirano chechigadzirwa hunongobva chete pamashoko akanyorwa mutsanangudzo yechigadzirwa. Ibasa remugamuchiri wechigadzirwa chedu kuona kuti chero kodzero dzevaridzi uye mitemo iripo nemutemo zvinocherechedzwa.
