CAS 80-62-6 methyl methacrylate MMA isukuye muri Ethanol

Ibisobanuro bigufi:

Methyl methacrylate （MMA）

Methyl methacrylate (MMA) ni ifumbire mvaruganda hamwe na chimique C5H8O2.Nibisukari bitagira ibara, bigashonga gato mumazi, kandi bigashonga mumashanyarazi menshi nka Ethanol.Bikoreshwa cyane nka monomer ya plexiglass, ariko kandi bikoreshwa mugukora ibindi bisigazwa, plastike, ibifuniko, ibifunga, amavuta, ibikoresho bingana kuri ibiti na cork, hamwe nimpapuro zogosha impapuro.

Ibinyabuzima

Ikizamini cya MITI-I, intangiriro yibanze ni 100ppm, kwibumbira hamwe ni 30ppm, naho gutesha agaciro ni 94% nyuma yibyumweru 2.

Ntabwo ari ibinyabuzima

Mu kirere, iyo hydroxyl radical yibanda kuri 5.00 × 105 / cm3, iyangirika ryubuzima bwa kabiri ni 7.4h (theoretical).

Iyo agaciro ka pH ari 7, 8, 9, 11, hydrolysis igice cyubuzima ni 4a, 140d, 14d, 3.4h bikurikiranye (theoretical)

Amatangazo yo gutwara abantu: Mugihe cyo gutwara, ibinyabiziga bitwara abantu bigomba kuba bifite ibikoresho byo kuzimya umuriro hamwe n’ibikoresho byihutirwa byihutirwa byubwoko butandukanye. Ni byiza gutwara mu gitondo na nimugoroba mu cyi.Ikamyo (tank) ikamyo ikoreshwa mu gutwara abantu igomba kuba ifite urunigi rwo hasi, kandi hashobora gushyirwaho umwobo mu kigega kugira ngo ugabanye ihungabana n’amashanyarazi ahamye. Birabujijwe rwose kuvanga no gutwara hamwe na okiside, acide, alkalis, halogene, imiti iribwa, nibindi mugihe cyubwikorezi, igomba kurindwa guhura nizuba ryizuba, imvura, nubushyuhe bwinshi.Mu gihe cyo guhagarara, irinde umuriro, amasoko yubushyuhe hamwe nubushyuhe bwinshi.
