Methyl methacrylate (MMA)

Kufotokozera:Methyl methacrylate (MMA) ndi yofunika organic mankhwala zopangira, makamaka ntchito popanga polymethyl methacrylate (plexiglass), polyvinyl kolorayidi wothandiza ARC ndi ntchito monga monoma wachiwiri kupanga akiliriki ulusi.Itha kukhala copolymerized ndi ena vinilu monomers kupeza mankhwala ndi katundu osiyanasiyana, amene ntchito monga utomoni, zomatira, ion kuwombola utomoni, pepala glazing wothandizira, nsalu kusindikiza ndi utoto wothandiza, wothandizila zikopa mankhwala, kudzoza mafuta zina, mafuta opanda mafuta kutsanulira mfundo depressants. , zotetezera kuthira zipangizo Amagwiritsidwa ntchito kwambiri ngati plasticizer kwa emulsions pulasitiki.

Makhalidwe:1. Zochepa poizoni 2. Zosakhazikika komanso zoyaka

Ntchito:Methyl methacrylate ndi yofunika mankhwala zopangira, izo makamaka ntchito monga polymethyl methacrylate monomers (organic galasi), komanso ndi vinilu monomer copolymerization kupeza chikhalidwe chosiyana cha mankhwala, komanso ntchito kupanga utomoni ena, pulasitiki, zomatira, zokutira, zothira mafuta, zolowera matabwa, zonyowa zamoto, utomoni wosinthira ma ion, mapepala, polishi, zida zothandizira nsalu, zochizira zikopa ndi zinthu zothira kutchinjiriza ndi zina zotero.

Malangizo onse:Njira zodzitetezera: ntchito yotsekedwa, kulimbikitsa mpweya wabwino.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Ndibwino kuti ogwira ntchito azivala zopumira zodzitetezera (zophimba theka), magalasi otetezera mankhwala, zovala zogwirira ntchito zotsutsana ndi static, ndi magolovesi osagwira mafuta.Khalani kutali ndi magwero a moto ndi kutentha, ndipo kusuta ndikoletsedwa kuntchito.Gwiritsani ntchito makina opumira ndi mpweya wosaphulika.Pewani nthunzi kuti isalowe mumlengalenga wapantchito.Pewani kukhudzana ndi okosijeni, zidulo, maziko, halogens.Pogwira ntchito, iyenera kuikidwa mopepuka ndikutsitsa kuti isawonongeke pakuyika ndi zotengera.Okonzeka ndi lolingana zosiyanasiyana ndi kuchuluka kwa moto zida ndi kutayikira mwadzidzidzi zipangizo chithandizo.Zotengera zopanda kanthu zitha kukhala zotsalira zowononga.

Phukusi:180/190kg kulemera ukonde, kapena chofunika monga Makasitomala.

Mayendedwe ndi kusungirako:

1. Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.Khalani kutali ndi gwero la moto ndi kutentha.Khalani kutali ndi kuwala.Kutentha kosungirako sikuyenera kupitirira 30 ℃.
2. Kupaka kumafunika kusindikizidwa osati kukhudzana ndi mpweya.
3. Iyenera kusungidwa mosiyana ndi okosijeni, ma acid, alkalis, halogens, ndi zina zotero, ndipo sayenera kusakanikirana.
4. Paulendo, iyenera kutetezedwa ku dzuwa, mvula, ndi kutentha kwakukulu.Panthawi yoyimitsa, khalani kutali ndi moto, magwero a kutentha ndi malo otentha kwambiri.
5. Chitoliro chotulutsa mpweya wa galimoto yonyamula chinthuchi chiyenera kukhala ndi chozimitsa moto, ndipo kugwiritsa ntchito zipangizo zamakina ndi zida zomwe zimakhala zosavuta kuphulika ndizoletsedwa kuti zilowetse ndi kutulutsa.
