Ukubuka Konke Komkhiqizo

I-anhydride yama-Maleic (Inombolo ye-CAS: 108-31-6) iyi-anhydride ephilayo engagcwalisiwe eyisihluthulelo enefomula yamakhemikhali engu-C₄H₂I-THE₃. Ibonakala njengama-crystalline flakes amhlophe noma aphuzi akhanyayo anephunga elimnandi, ukusebenza kahle kakhulu, kanye nokuhambisana okuhle nama-monomers namakhemikhali ahlukahlukene. Njengezinto zokusetshenziswa zamakhemikhali eziphilayo eziguquguqukayo, isetshenziswa kabanzi kuma-polymers, ezimbozweni, kwezemithi, kwezolimo, nasezimbonini zikawoyela negesi, okunikeza ukusebenza okuzinzile kanye nekhwalithi ethembekile yokukhiqiza kwezimboni.

Izicelo kanye Nokusetshenziswa

Ukuguquguquka kwe-Maleic Anhydride kuqhuba ukusetshenziswa kwayo ezimbonini eziningi:

Ama-Resins e-Polyester Angagcwalisiwe (UPR)

Isicelo Esiyinhloko: Ngaphezu kuka-50% womkhiqizo we-MA womhlaba wonke usetshenziswa kuma-UPR.

Imikhiqizo Yokusetshenziswa Ekugcineni: Amapulasitiki aqiniswe nge-fiberglass, amathangi, amapayipi, izingxenye zezimoto, ama-shells esikebhe, namaphaneli okwakha.

Ama-Copolymer

Izithasiselo Zamafutha Okugcoba: Zisetshenziswa njengengxenye kuma-copolymer asebenza njengezithuthukisi ze-viscosity index kanye nezihlakazi.

Ukwembozwa Komphezulu: Izinto zokusetshenziswa zama-resin e-alkyd asetshenziswa kumapende nezingubo zezimboni ezisezingeni eliphezulu.

Amakhemikhali Ezolimo

Okuphakathi: Kusetshenziswa ekuhlanganiseni izibulala-zinambuzane, imithi yokubulala ukhula (isb., i-Malathion), kanye nabalawuli bokukhula kwezitshalo.

Izithasiselo Zokudla

I-Fumaric ne-Malic Acid: I-Maleic Anhydride iyisandulela salezi zi-asidi ezingezona ezinobuthi, ezisetshenziswa njenge-acidulants eziphuzweni nasemikhiqizweni yokudla.

Ezinye Izinhlelo Zokusebenza

Usayizi Wephepha: Kusetshenziswa ekukhiqizweni kwe-alkyl ketene dimer (AKD), i-ejenti evamile yosayizi wephepha.

I-Tetrahydrofuran (THF) / I-Gamma-Butyrolactone (GBL): I-Cis-Butenedioic Anhydride iyindlela ebalulekile yokukhiqiza lezi zinyibilikisi ezibalulekile.

I-Succinic Anhydride: Iguqulwa kalula ibe yi-succinic anhydride yokwenziwa kwamakhemikhali ahlukahlukene.

Imininingwane Yobuchwepheshe

Into	Imininingwane
Ukubukeka	Ama-flakes acwebezelayo amhlophe noma aphuzi akhanyayo, akukho ukungcola okubonakalayo
Ubumsulwa (GC)	≥ 99.5 %
Indawo Yokuncibilika	52.5 - 54.5 °C
Indawo Yokubilisa	202 °C
Okuqukethwe komswakama	≤ 0.2 %
Okuqukethwe Komlotha	≤ 0.01 %
Umbala (i-APHA)	≤ 50

Izinzuzo Zomkhiqizo

2 5-Furandine High Purity: Ubumsulwa ≥ 99.5% buqinisekisa ukusebenza okuzinzile kokusabela futhi kunciphisa imikhiqizo engaphansi kokukhiqizwa okungezansi.

Ikhwalithi Ehambisanayo: Ukulawulwa kwekhwalithi okuqinile kuyo yonke inqubo yokukhiqiza (kusukela ekukhetheni izinto zokusetshenziswa kuya ekuhlolweni komkhiqizo oqediwe) kuqinisekisa ukuhambisana kweqembu ngalinye.

I-Reactivity Enhle Kakhulu: I-reactivity ephezulu ngama-diols, ama-amine, nama-monomers ivumela ukuhlanganiswa okuphumelelayo kwemikhiqizo engezansi.

Ukukhiqizwa Okuhambisana Nemvelo: Kwamukela ubuchwepheshe bokukhiqiza obuthuthukisiwe obusebenzisa amandla aphansi kanye nokuchitha okuncane, kuhambisana nezindinganiso zemvelo zomhlaba wonke.

Ukupakishwa Nokugcinwa Kwe-Maleic Anhydride Acid

Ukupakisha: Isisindo esiphelele esingu-25kg ngesikhwama sephepha se-kraft (esine-polyethylene liner yangaphakathi) noma izikhwama ezinkulu ezingu-1000kg, ezifanele ukuthuthwa olwandle nasemhlabeni.

Indawo Yokugcina: Gcina endaweni yokugcina epholile, eyomile, enomoya omuhle, kude nemithombo yokushisa, amalangabi avulekile, kanye nama-oxidant aqinile. Gwema ukumuncwa komswakama (kungase kufakwe i-hydrolyze ibe yi-maleic acid) kanye nokukhanya kwelanga okuqondile. Isikhathi sokulinda: izinyanga ezingu-12 ngaphansi kwezimo ezifanele zokugcina.

Ukuphepha Nokuphathwa kwe-Cis-Butenedioic Anhydride

Ukuzivikela Komuntu Siqu: Gqoka amagilavu, izibuko zokuvikela, kanye nemaski yothuli engangeni makhemikhali uma uphatha. Gwema ukuthintana ngqo nesikhumba, amehlo, kanye nomgudu wokuphefumula.

Usizo Lokuqala: Uma kwenzeka ukuthinta isikhumba, hlanza ngokushesha ngamanzi amaningi imizuzu eyi-15; uma kwenzeka ukuthinta amehlo, hlanza ngamanzi bese ucela usizo lwezokwelapha. Uma uphefumula, hamba uye emoyeni omusha bese uthintana nodokotela.

Ukuphatha Ukuchitheka: Munca izinto ezichithekile ngezimunca-manzi ezingangenisi lutho (isb. isihlabathi, i-vermiculite), ziqoqe ezitsheni ezivaliwe, bese uzilahla ngokwemithetho yendawo yemvelo. Ungachitheli emithonjeni yamanzi noma enhlabathini.
