    Phthalic Anhydride (PA) CAS Nambala: 85-44-9

    Chidule cha Zamalonda

    Phthalic Anhydride (PA) ndi chinthu chofunikira kwambiri chachilengedwe, chomwe chimapangidwa makamaka ndi oxidation ya ortho-xylene kapena naphthalene. Chimawoneka ngati kristalo yoyera yokhala ndi fungo losasangalatsa pang'ono. PA imagwiritsidwa ntchito kwambiri popanga mapulasitiki, ma polyester resins osakhuta, ma alkyd resins, utoto, ndi utoto, zomwe zimapangitsa kuti ikhale yofunika kwambiri pamakampani opanga mankhwala.

    Zinthu Zofunika Kwambiri

    • Kugwira Ntchito Kwambiri:PA ili ndi magulu a anhydride, omwe amakumana mosavuta ndi alcohols, amines, ndi mankhwala ena kuti apange ma esters kapena amides.
    • Kusungunuka Kwabwino:Amasungunuka m'madzi otentha, ma alcohols, ma ether, ndi zinthu zina zachilengedwe zosungunulira.
    • Kukhazikika:Yokhazikika pansi pa nthawi youma koma pang'onopang'ono imasungunuka kukhala phthalic acid pamene madzi ali m'kati.
    • Kusinthasintha:Amagwiritsidwa ntchito popanga mankhwala osiyanasiyana, zomwe zimapangitsa kuti ikhale yosinthasintha kwambiri.

    Mapulogalamu

    1. Zopangira pulasitiki:Amagwiritsidwa ntchito popanga ma ester a phthalate (monga DOP, DBP), omwe amagwiritsidwa ntchito kwambiri muzinthu za PVC kuti awonjezere kusinthasintha ndi kukonzedwa.
    2. Ma Resin a Polyester Osakhuta:Amagwiritsidwa ntchito popanga fiberglass, zokutira, ndi zomatira, zomwe zimapereka mphamvu zabwino kwambiri zamakanika komanso kukana mankhwala.
    3. Ma resini a Alkyd:Amagwiritsidwa ntchito mu utoto, zokutira, ndi ma varnish, zomwe zimapangitsa kuti utotowo ukhale wolimba komanso wonyezimira bwino.
    4. Utoto ndi Utoto:Amagwira ntchito ngati gawo lapakati pakupanga utoto ndi utoto wa anthraquinone.
    5. Ntchito Zina:Amagwiritsidwa ntchito popanga mankhwala ophera tizilombo, mankhwala ophera tizilombo, ndi zonunkhira.

     

    Kulongedza ndi Kusunga

    • Kupaka:Imapezeka m'matumba olemera makilogalamu 25, 500 kg, kapena matani. Ma phukusi opangidwa mwamakonda amapezeka mukawapempha.
    • Malo Osungira:Sungani pamalo ozizira, ouma, komanso opumira bwino. Pewani kukhudzana ndi chinyezi. Kutentha koyenera kosungira: 15-25℃.

    Zinthu Zofunika Kuganizira Pachitetezo ndi Zachilengedwe

    • Kukwiya:PA imakwiyitsa khungu, maso, ndi njira yopumira. Zipangizo zodzitetezera zoyenera (monga magolovesi, magalasi a maso, ndi zopumira) ziyenera kuvalidwa pogwira ntchito.
    • Kuyaka:Zimayaka koma siziyaka kwambiri. Sungani kutali ndi malawi otseguka ndi kutentha kwambiri.
    • Zotsatira za Chilengedwe:Tayani zinyalala motsatira malamulo a zachilengedwe kuti mupewe kuipitsa.

    Lumikizanani nafe

    Kuti mudziwe zambiri kapena kuti mupemphe chitsanzo, chonde funsani gulu lathu logulitsa. Tadzipereka kupereka zinthu zabwino kwambiri komanso ntchito yabwino kwambiri!

    Chiyambi cha Mankhwala a Methanol

    Chidule cha Zamalonda

    Methanol (CH₃OH) ndi madzi opanda mtundu, osasunthika komanso onunkhira pang'ono. Monga mowa wosavuta kugwiritsa ntchito, umagwiritsidwa ntchito kwambiri m'mafakitale a mankhwala, mphamvu, ndi mankhwala. Ukhoza kupangidwa kuchokera ku mafuta (monga gasi wachilengedwe, malasha) kapena zinthu zongowonjezedwanso (monga biomass, green hydrogen + CO₂), zomwe zimapangitsa kuti ukhale wofunikira kwambiri pakusintha kwa mpweya wochepa.

    Makhalidwe a Zamalonda

    • Kugwira Ntchito Mwachangu Poyatsa: Kuyatsa ndi kuyeretsa ndi mphamvu yapakati ya ma calories ndi mpweya wochepa.
    • Kusunga ndi Kunyamula Mosavuta: Madzi pa kutentha kwa chipinda, ochulukirapo kuposa hydrogen.
    • Kusinthasintha: Kugwiritsidwa ntchito ngati chakudya chamafuta komanso mankhwala.
    • Kukhazikika: "Green methanol" ingathandize kuti mpweya usakhale ndi mpweya woipa.

    Mapulogalamu

    1. Mphamvu ya Mafuta

    • Mafuta a Magalimoto: Mafuta a Methanol (M15/M100) amachepetsa mpweya woipa wochokera ku utsi.
    • Mafuta a m'nyanja: Amalowa m'malo mwa mafuta olemera m'magalimoto (monga zombo za Maersk zoyendetsedwa ndi methanol).
    • Maselo a Mafuta: Amayendetsa zida/ma drone kudzera m'maselo amafuta a methanol mwachindunji (DMFC).
