Kodi Maleic anhydride ndi chiyani?

Maleic anhydride, omwe amadziwikanso kuti dehydrated malic anhydride, ali ndi fungo lopweteka kwambiri pa kutentha kwa firiji, maonekedwe ndi makristasi oyera, ndipo mankhwala ndi C4H2O3.Kusungunuka kwa maleic anhydride: kusungunuka mu zosungunulira zambiri za organic monga madzi, acetone, benzene, chloroform;kulemera kwa maselo: 98.057;CAS: 108-31-6;Nambala ya EINECS: 203-571-6.

Kugwiritsa ntchito anhydride ya maleic

Maleic anhydride amagwiritsidwa ntchito ngati zopangira zopangira unsaturated polyester resin, alkyd resin, malathion mankhwala, kugwiritsa ntchito bwino kwambiri komanso mankhwala otsika poizoni 4049, ayodini wanthawi yayitali, ndi zina zambiri.

Ndiwophatikizanso zokutira, rosin wamwamuna, polymaleic anhydride, ndi maleic anhydride-styrene copolymer;

Komanso ndi organic mankhwala zopangira kupanga inki wothandiza, papermaking othandizira, plasticizers, tartaric acid, fumaric acid, tetrahydrofuran, etc.

Maleic anhydride kulongedza, kusunga ndi mayendedwe

Kusamala Pamayendedwe:Kuyikako kuyenera kukhala kokwanira ndipo kutsitsa kuyenera kukhala kotetezeka panthawi yonyamuka.Panthawi yoyendetsa, onetsetsani kuti chidebecho sichikudontha, kugwa, kugwa kapena kuwonongeka.Ndi zoletsedwa kwathunthu kusakaniza ndi kunyamula ndi okosijeni, zochepetsera, zidulo, mankhwala odyedwa, etc. Panthawi yoyendetsa, ziyenera kutetezedwa ku dzuwa, mvula, ndi kutentha kwakukulu.

Kusamala Posungira:Sungani m'nyumba yosungiramo zinthu zozizirirapo, zowuma, zolowera mpweya wabwino.Khalani kutali ndi gwero la moto ndi kutentha.Sungani chidebe chotsekedwa mwamphamvu.Ziyenera kusungidwa mosiyana ndi zotsekemera, zochepetsera, ma asidi, ndi mankhwala odyedwa, ndipo zisasakanizidwe.Okonzeka ndi mitundu yoyenera komanso kuchuluka kwa zida zozimitsa moto.Malo osungira ayenera kuperekedwa ndi zipangizo zoyenera kuti mukhale ndi kutaya.

Kusamala pakuyika:matumba apulasitiki kapena matumba awiri osanjikiza a kraft okhala ndi ng'oma zachitsulo zotseguka kapena zapakati;matumba apulasitiki kapena matumba a mapepala ansanjika awiri kunja kwa ng'oma za fiberboard, ng'oma za plywood, ndi ng'oma za makatoni;matumba apulasitiki kunja kwa ng'oma zapulasitiki (zolimba);ng'oma zapulasitiki (madzi).
