    Anhidride ya Maléique

    Igikoko c’amazi c’umubiri (CAS No.: 108-31-6) ni igikoko c’umubiri c’ingenzi kidafise amazi y’umubiri gifise ubuhinga bwa C4H2O3. Iboneka nk’ibipande vy’amabuye y’agaciro vyera canke vy’umuhondo ukeye bifise akamoto gakomeye, bishobora gukora cane, kandi bikaba bihuye neza cane n’ibintu bitandukanye bita monomere be n’ibintu bitandukanye. Nk’ikintu gikoreshwa cane mu bikoresho vy’ubuhinga bwa none, gikoreshwa cane mu bikoresho vy’ubuhinga bwa none, mu bikoresho vy’ubuhinga bwa none, mu bikoresho vy’ubuhinga bwa none, mu vy’uburimyi, no mu nganda z’amavuta na gazi, kigatanga ubushobozi buhamye n’uburyo bwo kwizigirwa bwo gukora ibikorwa vy’inganda.

      Incamake y'igicuruzwa

      Igitera amazi y’umubiri (CAS No.: 108-31-6) ni amazi y’umubiri atagira amazi menshi afise ubuhinga bwa C .4H2MU3. Iboneka nk’ibipande vy’amabuye y’agaciro vyera canke vy’umuhondo ukeye bifise akamoto gakomeye, bishobora gukora cane, kandi bikaba bihuye neza cane n’ibintu bitandukanye bita monomere be n’ibintu bitandukanye. Nk’ikintu gikoreshwa mu buryo bwinshi, gikoreshwa cane mu bikoresho vy’ubuhinga bwa none, mu gupfuka, mu gukora imiti, mu buhinzi, no mu nganda z’amavuta na gazi, kigatanga ubushobozi buhamye n’uburyo bwo kwizigirwa bwo gukora ibikorwa vy’inganda.​

      Ibikoresho n'Ikoreshwa

      Ubushobozi bwa Maleic Anhydride butuma ikoreshwa mu bikorwa vyinshi:

      Amaresini y'ivyuma bitagira amazi (UPR)

      Ikoreshwa rya mbere: Ibirenga 50% vy’ibikorwa vya MA kw’isi yose bikoreshwa mu UPRs.

      Ibintu bikoreshwa mu mpera: Amapulasitike akomeye, ibidengeri, amatiyo, ibihimba vy’imodoka, ivyuma vy’ubwato be n’ivyuma vy’ubwubatsi.

      Ivyuma bifatanya

      Ivyongera ku mavuta y’amavuta: Bikoreshwa nk’igice kiri mu bihimba vy’umubiri bikora nk’ivyo gutuma uburemere bw’ibintu bugenda neza no gushwiragiza.

      Ivyo Gupfuka ku Mubiri: Igikoresho ca mbere co guhingura amarangi y’ivyuma yitwa alkyde akoreshwa mu gupfuka amarangi n’ibindi bikoresho vy’inganda vy’agaciro kanini.

      Imiti y'uburimyi

      Ivy’imbere: Bikoreshwa mu gukora imiti yica udukoko, imiti yica ivyatsi (nk’akarorero, Malathion), n’imiti igabanya ukukura kw’ibimera.

      Ivyongera mu biribwa

      Fumaric na Malic Acid: Maleic Anhydride ni ikintu gitangura izo aside zidatera ubumara, zikoreshwa nk’ibitera aside mu binyobwa no mu vyo kurya.

      Ibindi bikoresho

      Gupima Ingano y’Impapuro: Ikoreshwa mu guhingura ikintu citwa alkyl ketene dimer (AKD), kikaba ari ikintu gisanzwe gikoreshwa mu gupima ingano z’impapuro.

      Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): Anhidride ya Cis-Butenedioïque ni inzira ihambaye yo guhingura ivyo bikoresho vy’agaciro.

      Anhydride Succinique: Ihindurwa bitagoranye ikaba anhydride succinique kugira ngo ikoreshe mu gukora ibikorwa bitandukanye vy’imiti.

      Ibisobanuro vy'ubuhinga

      Umutwe Ibisobanuro
      Isura Ivyuma vyera canke vy’umuhondo ukeye, ata buhumane buboneka
      Ubusuku (GC) ≥ 99.5 %
      Ikibanza co gushongera 52,5 - 54,5 °C
      Intumbero yo guteka 202 °C
      Ibirimwo ubukonje ≤ 0.2 %
      Ivu ry'ibirimwo ≤ 0,01 %
      Ibara (APHA) ≤ 50

      Inyungu z'igicuruzwa

      2 5-Furandine Ubusuku bukomeye: Ubusuku ≥ 99.5% butuma habaho ubushobozi bwo gusubiza neza kandi bugabanura ibiva mu guhingura ibintu biva mu mazi.
      Uburyo Buhoraho: Gucungera neza uburyo mu gihe cose c’uguhingura (kuva ku guhitamwo ibikoresho vya mbere gushika ku gusuzuma ibintu bimaze gukorwa) bituma habaho uguhuza kw’ibice bimwebimwe.
      Ivyiza cane: Ivyiza vyinshi bikorana n’ibinyabuzima bita diols, amines, na monomeres biratuma habaho ugukorana neza kw’ibintu biva mu mazi.
      Uguhingura ibintu bidahungabanya ibidukikije: Bikoresha ubuhinga buteye imbere bwo guhingura ibintu bikoresha inguvu nke kandi bikoresha imyanda myinshi, bihuye n’ingingo mfatirwako mpuzamakungu zijanye n’ibidukikije.
       

      Asidi ya Maleic Anhydride Gupfunyika no kubika

      Ivyo gupfunyika: 25kg uburemere bw’urusenga ku musaho w’impapuro z’ubuhinga (ufise ivyuma vy’imbere vy’impuzu) canke imifuko 1000kg ya jumbo, ibereye gutwara mu kiyaga no ku butaka.
      Uko ubibika: Bibike mu bubiko bukonje, bwumye, bufise umwuka mwiza, kure y’aho ubushuhe buva, imbeya zifunguye be n’ibintu bikomeye bitera umuriro. Irinde gufata ubukonje (bushobora guhinduka aside maléique) n’umuco w’izuba. Igihe co kubika: amezi 12 iyo ibitswe neza.
       

      Umutekano wa Cis-Butenedioic Anhydride n'Ugukoresha

      Ukwikingira: Ambara amaganzu adashobora guterwa n’imiti, amataratara, n’igipfukisho c’inkungugu igihe ukoresha. Irinde gukorana n’urukoba, amaso n’inzira y’uguhema.
      Imfashanyo ya mbere: Iyo umuntu akoze ku rukoba, uce ubwo nyene akaraba n’amazi menshi mu minota 15; iyo umuntu akoranye n’amaso, uyisukure n’amazi, urondere ubuvuzi. Iyo uhumeka, genda mu kirere ciza maze ugende ku muganga.
      Gufata ibintu vyamenetse: Gufata ibintu vyamenetse bikoresheje ibintu bitagira ubushobozi (nk’umusenyi, vermiculite), kubikorakoranya mu bikoresho bipfutse, hanyuma ubijugunye hakurikijwe amategeko agenga ibidukikije yo mu karere. Ntushire mu masoko y’amazi canke mw’ivu.
