Maleic Anhydride
Kulanga-langa zintu
Maleic anhydride (CAS No.: 108-31-6) nchintu chipati chitakwe busani bujisi fomuyula ya C₄H₂CHI₃. Chilibonya mbuli mabwe aatuba naa aasalala pyu aajisi tununkilizyo tupati, aanguzu zyakusanduka, alimwi akubeleka kabotu ama monomers aamakemikalu aasiyene. Mbuli chintu chibelesegwa munzila zyiingi, chibelesegwa kapati muma polymers, ma coatings, pharmaceutics, mulimi, ama oil & gas, kupa kuti kube kubeleka kabotu akusyomeka mukupanga zintu mumafakitali.
Kubelesya akubelesya�
Kukonzya kwa Maleic Anhydride kuchitila kuti ibelesyegwe mumakwebo miingi:
Zibelesyo zya polyester zitakwe busani (UPR)
Kubelesya kutaanzi: Kwiinda 50% ya MA iizwa munyika yoonse ibelesyegwa mu UPRs.
Zibelesyo zyakumanizya: Mapulasitiki aayumizigwa agilazi, matanki, mapaipi, zibeela zyamyootokala, zibeela zyabwaato, antoomwe amapanelo aakuyaka.
Ma Copolymers
Ziyungizyo zyamafuta aakusanzya: Zibelesyegwa mbuli chintu muma copolymers abeleka mbuli zintu zisumpula viscosity index akumwaika.
Kuvwumba Atala: Nchintu chibelesegwa kupanga ma alkyd resins aabelesyegwa mukupenta akuvwumba kwamumakkampani.
Makemikalu aabulimi
Chaakati: Chibelesyegwa mukupanga misamu iijaya tuzunda, misamu iijaya nsaku (nkokuti, Malathion), antoomwe azintu zipa kuti zisyango zikomene.
Ziyungizyidwe muzyakulya
Fumaric a Malic Acid: Maleic Anhydride nchintu chitalikila ma asidi aaya aatakwe toxic, abelesyegwa mbuli asidi muzyakunywa amuzyakulya.
Zimwi Zibelesyo
Kupima bupati bwapepa: Kubelesyegwa mukupanga alkyl ketene dimer (AKD), musamu uudumide wakupima bupati bwapepa.
Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): Cis-Butenedioic Anhydride ninzila iiyandika kapati yakupanga zintu eezyi ziyandisi.
Succinic Anhydride: Ilakonzya kusandulwa kuba succinic anhydride kuti ibelesegwe mukupanga misamu isiyene-siyene.
