Aside ya Methacrylic (aside 2-Methyl-2-propenoic)

Imiterere y'ibinyabutabire

Aside ya Methacrylic, mu magambo make MAA, ni ikintu kigizwe n'ibinyabuzima. Iki kintu kidafite ibara kandi gifite imiterere y'amazi ni aside karbokisilike ifite impumuro mbi. Irashongesha mu mazi ashyushye kandi ishobora kuvangwa n'ibintu byinshi biyungurura ibinyabuzima. Aside ya Methacrylic ikorwa mu nganda ku rugero runini nk'intangiriro ya esters zayo, cyane cyane methyl methacrylate (MMA) na poly (methyl methacrylate) (PMMA). Methacrylate zifite akamaro kenshi, cyane cyane mu gukora polymers zifite amazina y'ubucuruzi nka Lucite na Plexiglas. MAA iboneka mu buryo busanzwe mu mavuta make ya chamomile ya Roma.

Porogaramu

Aside ya Methacrylic ikoreshwa mu gukora resins na pulasitiki za methacrylate. Ikoreshwa nka Monomer mu ma resins na polymers nini, synthesis ya organic. Polymer nyinshi zishingiye kuri esters za aside, nka methyl, butyl, cyangwa isobutyl esters. Acide ya Methacrylic na methacrylate esters zikoreshwa mu gutegura polymers zitandukanye [→ Polyacrylamides na Poly (Acides Acrylic), → Polymethacrylates]. Poly (methyl methacrylate) ni polymer y'ibanze muri iki cyiciro, kandi itanga pulasitiki idafite amazi kandi ikomeye ikoreshwa mu buryo bw'urupapuro mu gukaranga, ibimenyetso, amatara, n'urumuri.

Dukurikije ubunararibonye bwacu, ibicuruzwa bishobora kubikwa amezi 12 uhereye igihe byagejejwe mu gihe bibitswe mu bikoresho bifunze neza, birinzwe urumuri n'ubushyuhe kandi bikabikwa ku bushyuhe buri hagati ya 5 na 30°C.
