Maleic Anhydride-1

Maleic anhydride (CAS No.: 108-31-6) ndi anhydride yofunika kwambiri yachilengedwe yopanda mafuta yokhala ndi formula ya mankhwala ya C₄H₂O₃. Imawoneka ngati ma crystalline flakes oyera kapena achikasu owala okhala ndi fungo lopweteka, reactivity yayikulu, komanso yogwirizana bwino ndi ma monomers ndi mankhwala osiyanasiyana. Monga zinthu zopangira mankhwala achilengedwe, imagwiritsidwa ntchito kwambiri mu ma polima, zokutira, mankhwala, ulimi, ndi mafakitale amafuta ndi gasi, zomwe zimapangitsa kuti ntchito ikhale yokhazikika komanso yodalirika popanga mafakitale.

Maleic anhydride (CAS No.: 108-31-6) ndi anhydride yofunika kwambiri yachilengedwe yopanda mafuta yokhala ndi formula ya mankhwala ya C₄H₂CHONSE₃Imawoneka ngati ma crystalline flakes oyera kapena achikasu owala okhala ndi fungo loipa, reactivity yapamwamba, komanso imagwirizana bwino ndi ma monomers ndi mankhwala osiyanasiyana. Monga zinthu zopangira mankhwala achilengedwe, imagwiritsidwa ntchito kwambiri mu ma polima, zokutira, mankhwala, ulimi, ndi mafakitale amafuta ndi gasi, zomwe zimapereka magwiridwe antchito okhazikika komanso khalidwe lodalirika popanga mafakitale.

Mapulogalamu ndi Ntchito

Kusinthasintha kwa Maleic Anhydride kumayambitsa kugwiritsidwa ntchito kwake m'mafakitale osiyanasiyana:

Ma Resins a Polyester Osakhuta (UPR)

Kugwiritsa Ntchito Koyamba: Kuposa 50% ya kupanga MA padziko lonse lapansi kumagwiritsidwa ntchito mu UPRs.

Zogwiritsidwa Ntchito Pomaliza: Mapulasitiki olimbikitsidwa ndi fiberglass, matanki, mapaipi, zida zamagalimoto, ma shells a boti, ndi mapanelo omanga.

Ma Copolymers

Zowonjezera Mafuta Opaka: Zimagwiritsidwa ntchito ngati gawo la ma copolymer omwe amagwira ntchito ngati zowongolera ndi zotulutsa ma viscosity index.

Zophimba Pamwamba: Zipangizo zopangira ma resin a alkyd omwe amagwiritsidwa ntchito mu utoto ndi zophimba zapamwamba zamafakitale.

Mankhwala a Zaulimi

Wapakatikati: Amagwiritsidwa ntchito popanga mankhwala ophera tizilombo, mankhwala ophera udzu (monga Malathion), ndi owongolera kukula kwa zomera.

Zowonjezera Zakudya

Fumaric ndi Malic Acid: Maleic Anhydride ndiye chiyambi cha ma acids osakhala ndi poizoni awa, omwe amagwiritsidwa ntchito ngati acidulants mu zakumwa ndi zakudya.

Mapulogalamu Ena

Kukula kwa Pepala: Amagwiritsidwa ntchito popanga alkyl ketene dimer (AKD), yomwe imagwiritsidwa ntchito popangira kukula kwa pepala.

Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): Cis-Butenedioic Anhydride ndi njira yofunika kwambiri yopangira zinthu zosungunulira izi zofunika.

Succinic Anhydride: Imasinthidwa mosavuta kukhala succinic anhydride yopangira mankhwala osiyanasiyana.

Mafotokozedwe Aukadaulo

Ubwino wa Zamalonda

2 5-Furandine High Purity: Purity ≥ 99.5% imatsimikizira kuti zinthu zikuyenda bwino komanso imachepetsa zinthu zina zomwe zimachokera kuzinthu zomwe zimapangidwa.

Ubwino Wokhazikika: Kuwongolera bwino kwambiri khalidwe panthawi yonse yopangira (kuyambira kusankha zinthu zopangira mpaka kuwunika komaliza kwa chinthu) kumatsimikizira kuti zinthu zonse zimakhala zofanana.

Kuchita Zinthu Moyenera Kwambiri: Kuchita zinthu mopitirira muyeso pogwiritsa ntchito ma diol, ma amine, ndi ma monomers kumathandiza kuti zinthu zotsalira zipangidwe bwino.

Kupanga Kosawononga Chilengedwe: Kumagwiritsa ntchito ukadaulo wapamwamba wopanga womwe umagwiritsa ntchito mphamvu zochepa komanso kuwononga pang'ono, mogwirizana ndi miyezo yapadziko lonse lapansi yokhudza chilengedwe.

Kupaka ndi Kusunga Maleic Anhydride Acid

Kupaka: 25kg kulemera konse pa thumba lililonse la pepala la kraft (lokhala ndi polyethylene liner yamkati) kapena matumba akuluakulu a 1000kg, oyenera mayendedwe apanyanja ndi pamtunda.

Kusungira: Sungani m'nyumba yosungiramo zinthu yozizira, youma, komanso yodutsa mpweya wabwino, kutali ndi magwero a kutentha, malawi otseguka, ndi ma oxidant amphamvu. Pewani kuyamwa chinyezi (kungayambitse hydrolyze kukhala maleic acid) komanso kuwala kwa dzuwa mwachindunji. Nthawi yosungira: miyezi 12 pansi pa mikhalidwe yoyenera yosungira.

Chitetezo ndi Kusamalira Cis-Butenedioic Anhydride

Chitetezo Chanu: Valani magolovesi, magalasi a maso, ndi chigoba choteteza fumbi chomwe sichimakhudzidwa ndi mankhwala mukamagwira ntchito. Pewani kukhudzana mwachindunji ndi khungu, maso, ndi njira zopumira.

Chithandizo Choyamba: Ngati yakhudzana ndi khungu, tsukani nthawi yomweyo ndi madzi ambiri kwa mphindi 15; ngati yakhudzana ndi maso, tsukani ndi madzi ndipo funani thandizo la dokotala. Ngati mwapumira, pitani ku mpweya wabwino ndikufunsa dokotala.

Kusamalira Kutaya Madzi: Kuyamwa zinthu zomwe zatayika ndi zinthu zosagwira ntchito (monga mchenga, vermiculite), sonkhanitsani m'zidebe zotsekedwa, ndikutaya motsatira malamulo a chilengedwe. Musatulutse madzi m'magwero a madzi kapena m'nthaka.
