    I-Maleic Anhydride

    I-Maleic anhydride (CAS No.: 108-31-6) yi-anhydride ye-organic engakagcwali enefomula yamakhemikhali ye-C4H2O3. Ibonakala njengeenhluthu ezimhlophe nofana eziphuzi ezinephunga elibukhali, ukuphendula okuphezulu, nokukhambisana okuhle khulu nama-monomers namakhemikhali ahlukahlukeneko. Njengesisetjenziswa samakhemikhali esiphilako esihlukahlukeneko, sisetjenziswa khulu kuma-polymer, ama-coating, imithi, kwezokulima, kanye namabubulo we-oli negesi, okunikela ukusebenza okuzinzileko kanye nekhwalithi ethembekileko yokukhiqiza amabubulo.

      Ukuhlolisisa komkhiqizo

      I-Maleic anhydride (CAS No.: 108-31-6) yi-anhydride ye-organic engakagcwali enefomula yamakhemikhali ye-C₄H₂I₃. Ibonakala njengeenhluthu ezimhlophe nofana eziphuzi ezinephunga elibukhali, ukuphendula okuphezulu, nokukhambisana okuhle khulu nama-monomers namakhemikhali ahlukahlukeneko. Njengesisetjenziswa samakhemikhali esiphilako esihlukahlukeneko, sisetjenziswa khulu kuma-polymer, ama-coating, imithi, kwezokulima, kanye namabubulo we-oli negesi, okunikela ukusebenza okuzinzileko kanye nekhwalithi ethembekileko yokukhiqiza amabubulo.�

      Iinsetjenziswa nokusetjenziswa

      Ukusebenza kwe-Maleic Anhydride kwenza bona isetjenziswe emabubulweni amanengi:

      I-Unsaturated Polyester Resins (UPR)

      Isicelo esiyinhloko: Ngaphezulu kwama-50% womkhiqizo we-MA wephasi loke usetjenziswa kuma-UPR.

      Imikhiqizo yokugcina: Amapulasitiki aqiniswe nge-fibreglass, amathangi, amapayipi, amalunga weenkoloyi, ama-hull wesikepe, namaphaneli wokwakha.

      Ama-copolymers

      Iinthako zamafutha wokuthambisa: Zisetjenziswa njengengcenye yama-copolymer asebenza njengeenthuthukisi ze-viscosity index kanye nama-dispersants.

      Ukugcotshwa kwephasi: Into engakasetjenzwa yama-alkyd resins asetjenziselwa upende wekhwalithi ephezulu yamabubulo.

      Amakhemikhali wezokulima

      Okuphakathi: Isetjenziswa ekuhlanganisweni kwemithi yokubulala iinlwana, imithi yokubulala ukhula (isib., i-Malathion), kanye neenlawuli zokukhula kweentjalo.

      Iinthako zokudla

      I-Fumaric ne-Malic Acid: I-Maleic Anhydride yisandulela sama-esidi angasiwo ubuthi, asetjenziswa njenge-asidi eenselweni nemikhiqizweni yokudla.

      Ezinye iinsetjenziswa

      Ukulinganisa iphepha: Isetjenziswa ekukhiqizeni i-alkyl ketene dimer (AKD), into ejayelekileko yokulinganisa iphepha.

      I-Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): I-Cis-Butenedioic Anhydride yindlela eqakathekileko yokukhiqiza iinsombululo eziqakathekileko.

      I-Succinic Anhydride: Itjhugululwa lula ibe yi-succinic anhydride malungana namakhemikhali ahlukahlukeneko.

      Iinqophiso zethekhnikhi

      I-ayithemu Ukucaciswa
      Ukuvela Amaflekhi amhlophe nofana aphuzi akhanyako, akukho ukungcola okubonakalako
      Ukuhlanzeka (GC) ≥ 99.5 %
      Indawo yokuncibilika 52.5 - 54.5 °C
      Indawo yokubila 202 °C
      Okuqukethwe komswakama ≤ 0.2 %
      Okuqukethwe mlotha ≤ 0.01 %
      Umbala (APHA) ≤ 50

      Iinzuzo zomkhiqizo

      2 5-Furandine High Purity: Purity ≥ 99.5% kuqinisekisa ukusebenza okuzinzileko kokuphendula begodu kwehlisa imikhiqizo engaphasi kwemikhiqizo.
      Ikhwalithi engaguqukiko: Ukulawulwa kwekhwalithi okuqinileko kiyo yoke ikambiso yokukhiqiza (kusukela ekukhethweni kwepahla engakasetjenzwa ukuya ekuhlolweni komkhiqizo oqediweko) kuqinisekisa ukungaguquguquki kwesiquntu ukuya esiqhemeni.
      Ukusabela okuhle khulu: Ukusabela okuphezulu nama-diols, ama-amines, nama-monomers kwenza bona kube nokuhlanganiswa okuphumelelako kwemikhiqizo.
      Ukukhiqiza Okungalimazi Ibhoduluko: Kwamukela ithekhnoloji yokukhiqiza ethuthukileko ngokusebenzisa amandla aphasi nokulahlwa okuncani, ngokukhambisana namazinga wezebhoduluko weentjhabatjhaba.
       

      Ukupakisha nokubulungwa kwe-Maleic Anhydride Acid

      Ukuphakheja: 25kg ubunzima obupheleleko ngesikhwama sephepha ngasinye (esinelayini yangaphakathi ye-polyethylene) nofana i-1000kg yezikhwama ezikulu, ezilungele ukuthuthwa ngelwandle nephasi.
      Ukubulunga: Beka endaweni epholileko, eyomileko, enommoya omuhle, kude nemithombo yomtjhiso, amalangabi avulekileko, nama-oxidant aqinileko. Balekela ukumuncwa komswakama (kungaba yi-hydrolysis ibe yi-maleic acid) nokukhanya kwelanga okuqondileko. Isikhathi sokuphila: iinyanga ezili-12 ngaphasi kweemeko ezifaneleko zokugcina.
       

      Ukuphepha nokuphathwa kwe-Cis-Butenedioic Anhydride

      Ukuzivikela: Yembatha amagilavu ​​angathathwa makhemikhali, amagogolosi, kanye nemaski yothuli lokha nawuphathako. Balekela ukuthintana ngqo nesikhumba, amehlo, kanye nendlela yokuphefumula.
      Isizo lokuthoma: Nawuthintana nesikhumba, hlambulula msinyana ngamanzi amanengi imizuzu eli-15; lokha nawuthintana namehlo, hlambulula ngamanzi bese ufuna isizo lezokwelapha. Nawuphefumulelwako, tjhinga emoyeni ophretjhi bese uthintana nodorhodera.
      Ukuphathwa kokuchitheka: Munya izinto ezichithekileko ngezinto ezimunyako (isib., isihlabathi, i-vermiculite), zibuthelele eentweni ezivaliweko, bese uzilahla ngokuya kwemithetho yezebhoduluko yendawo. Ungalahli emithonjeni yamanzi nofana ehlabathini.
