I-Maleic Anhydride-1

I-anhydride yeMaleic (iNombolo yeCAS: 108-31-6) yi-anhydride ye-organic engagcwaliyo enefomyula yekhemikhali ye-C₄H₂O₃. Ibonakala njengee-crystalline flakes ezimhlophe okanye ezimthubi ezikhanyayo ezinevumba elimnandi, i-reactivity ephezulu, kwaye ihambelana kakuhle nee-monomers kunye neekhemikhali ezahlukeneyo. Njengezinto ezisetyenziswa kakhulu kwi-organic chemical raw, isetyenziswa kakhulu kwi-polymers, kwiingubo, kwiimveliso zamayeza, kwezolimo, nakwimizi-mveliso yeoyile negesi, ibonelela ngokusebenza okuzinzileyo kunye nomgangatho othembekileyo kwimveliso yemizi-mveliso.

Isishwankathelo seMveliso

I-anhydride yeMaleic (iNombolo yeCAS: 108-31-6) yi-anhydride ebalulekileyo ye-organic engagcwaliyo enefomyula yekhemikhali ye-C₄H₂I-₃Ibonakala njengee-crystalline flakes ezimhlophe okanye ezimthubi kancinci ezinevumba elibi, i-reactivity ephezulu, kwaye ihambelana kakuhle nee-monomers ezahlukeneyo kunye neekhemikhali. Njengezinto ezisetyenziswa kakhulu kwi-organic chemical raw material, isetyenziswa kakhulu kwi-polymers, kwi-coatings, kwi-pharmaceuticals, kwi-ezolimo, nakwi-oyile negesi, ibonelela ngokusebenza okuzinzileyo kunye nomgangatho othembekileyo kwimveliso yemizi-mveliso.

Izicelo kunye nokusetyenziswa

Ukuguquguquka kweMaleic Anhydride kuqhuba ukusetyenziswa kwayo kumashishini amaninzi:

IiResins zePolyester ezingagcwaliyo (UPR)

Isicelo Esiphambili: Ngaphezulu kwe-50% yemveliso ye-MA yehlabathi isetyenziswa kwi-UPRs.

Iimveliso Zokusetyenziswa Ekugqibeleni: Iiplastiki eziqiniswe nge-fiberglass, iitanki, iipayipi, iindawo zeemoto, ii-hulls zeenqanawa, kunye neepaneli zokwakha.

IiCopolymers

Izithako zeOyile yokuthambisa: Zisetyenziswa njengenxalenye kwi-copolymers ezisebenza njenge-viscosity index improvers kunye ne-dispersants.

Iingubo zomphezulu: Zizinto ezisetyenziswa kwii-alkyd resins ezisetyenziswa kwiipeyinti nakwiingubo zoshishino ezikumgangatho ophezulu.

Iikhemikhali zezolimo

Iphakathi: Isetyenziswa ekuhlanganiseni izibulali-zinambuzane, izibulali-zinambuzane (umz., iMalathion), kunye nabalawuli bokukhula kwezityalo.

Izongezo zokutya

I-Fumaric kunye ne-Malic Acid: I-Maleic Anhydride sisandulela sezi asidi zingenabungozi, ezisetyenziswa njenge-acidulants kwiziselo nakwiimveliso zokutya.

Ezinye izicelo

Ubungakanani bephepha: Isetyenziswa ekuveliseni i-alkyl ketene dimer (AKD), iarhente eqhelekileyo yokulinganisa iphepha.

I-Tetrahydrofuran (THF) / I-Gamma-Butyrolactone (GBL): I-Cis-Butenedioic Anhydride yindlela ebalulekileyo yokuvelisa ezi zinyibilikisi zixabisekileyo.

I-Succinic Anhydride: Iguqulwa ngokulula ibe yi-succinic anhydride kwiimveliso ezahlukeneyo zeekhemikhali.

Iingenelo zeMveliso

2 5-Furandine High Purity: Ubumsulwa ≥ 99.5% buqinisekisa ukusebenza okuzinzileyo kwempendulo kwaye kunciphisa iimveliso eziphumayo kwimveliso esezantsi.

Umgangatho Ohlala Uhleli: Ulawulo oluqinileyo lomgangatho kuyo yonke inkqubo yemveliso (ukusuka ekukhetheni izinto eziluhlaza ukuya ekuhlolweni kwemveliso egqityiweyo) kuqinisekisa ukuhambelana kwebhetshi nganye.

I-Reactivity Egqwesileyo: I-reactivity ephezulu kunye nee-diols, ii-amines, kunye nee-monomers ivumela ukwenziwa ngokufanelekileyo kweemveliso ezisezantsi.

Imveliso Enobuhlobo Nokusingqongileyo: Yamkela iteknoloji yemveliso ephucukileyo esebenzisa amandla aphantsi kunye nenkunkuma encinci, ithobela imigangatho yezendalo yamazwe ngamazwe.

Ukupakishwa kunye nokugcinwa kweMaleic Anhydride Acid

Ukupakisha: Ubunzima obupheleleyo obuyi-25kg ngebhegi yephepha le-kraft (ene-polyethylene liner yangaphakathi) okanye iibhegi ezinkulu eziyi-1000kg, ezifanelekileyo ukuthuthwa ngolwandle nasemhlabeni.

Indawo yokugcina: Gcina kwindawo yokugcina epholileyo, eyomileyo, enomoya ococekileyo, kude nemithombo yobushushu, amadangatye avulekileyo, kunye nee-oxidants ezinamandla. Kuphephe ukufunxwa komswakama (kusenokuyijika ibe yi-maleic acid) kwaye kuthintelwe ukukhanya kwelanga ngqo. Ixesha lokugcinwa: Iinyanga ezili-12 phantsi kweemeko ezifanelekileyo zokugcina.

Ukhuseleko kunye nokuphathwa kwe-Cis-Butenedioic Anhydride

Ukhuseleko Lomntu: Nxiba iiglavu, iiglasi zokukhusela uthuli, kunye nemaski yokukhusela uthuli xa uphatha. Kuphephe ukudibana ngqo nolusu, amehlo, kunye nendlela yokuphefumla.

Uncedo Lokuqala: Ukuba ulusu luthe lwadibana, hlambulula ngoko nangoko ngamanzi amaninzi imizuzu eli-15; ukuba uthe lwadibana emehlweni, hlambulula ngamanzi uze ufumane uncedo lwezonyango. Ukuba uphefumle, yiya emoyeni omtsha uze udibane nogqirha.

Ukuphatha Ukuchitheka: Funxa izinto ezichithekileyo ngezifunxi ezingangenisi manzi (umz. isanti, i-vermiculite), ziqokelele kwizikhongozeli ezivaliweyo, uze uzilahle ngokwemigaqo yendawo yokusingqongileyo. Musa ukuzikhuphela kwimithombo yamanzi okanye emhlabeni.
