ʻO ka maleic anhydride (CAS No.: 108-31-6) kahi anhydride organik unsaturated koʻikoʻi me kahi ʻano kemika o C₄H₂KA₃ʻIke ʻia ia he mau ʻāpana kristal keʻokeʻo a melemele māmā paha me kahi ʻala ʻawaʻawa, ka hana kiʻekiʻe, a me ka hoʻohālikelike maikaʻi loa me nā monomers a me nā kemika like ʻole. Ma ke ʻano he mea maka kemika organik versatile, hoʻohana nui ʻia ia i nā polymers, nā uhi, nā lāʻau lapaʻau, ka mahiʻai, a me nā ʻoihana aila a me ke kinoea, e hāʻawi ana i ka hana paʻa a me ka maikaʻi hilinaʻi no ka hana ʻoihana.ʻ

Nā noi a me nā hoʻohana

ʻO ka versatility o Maleic Anhydride e hoʻokele i kona hoʻohana ʻana ma nā ʻoihana he nui:

Nā Resins Polyester Unsaturated (UPR)

Ka Hoʻohana Mua: Ma luna o 50% o ka hana MA honua e hoʻohana ʻia ana i nā UPR.

Nā Huahana Hoʻohana Hope Loa: Nā plastik i hoʻoikaika ʻia me ka Fiberglass, nā pahu wai, nā paipu, nā ʻāpana kaʻa, nā kino o ka waʻa, a me nā panela kūkulu.

Nā Copolymers

Nā Mea Hoʻohui ʻAila Lubricant: Hoʻohana ʻia ma ke ʻano he ʻāpana i loko o nā copolymers e hana ma ke ʻano he mea hoʻomaikaʻi i ka viscosity index a me nā mea hoʻolaha.

Nā Uhi ʻIli: He mea maka no nā resins alkyd i hoʻohana ʻia i nā pena ʻoihana kiʻekiʻe a me nā uhi ʻili.

Nā Kemika Mahiʻai

Waena: Hoʻohana ʻia i ka synthesis o nā pesticides, herbicides (e laʻa, Malathion), a me nā mea hoʻoponopono ulu mea kanu.

Nā Mea Hoʻohui Meaʻai

ʻAkika Fumaric a me Malic: ʻO Maleic Anhydride kahi mea mua i kēia mau waikawa ʻona ʻole, i hoʻohana ʻia e like me nā acidulants i nā mea inu a me nā huahana meaʻai.

Nā noi ʻē aʻe

Ka Ana Pepa: Hoʻohana ʻia i ka hana ʻana o ka alkyl ketene dimer (AKD), kahi mea ana maʻamau no ka pepa.

Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): ʻO Cis-Butenedioic Anhydride kahi ala koʻikoʻi no ka hana ʻana i kēia mau mea hoʻoheheʻe waiwai nui.

ʻAnhydride Succinic: Hoʻololi koke ʻia i ka anhydride succinic no nā hana kemika like ʻole.

Nā Kikoʻī ʻenehana

Nā Pōmaikaʻi o ka Huahana

2 5-Furandine Maʻemaʻe Kiʻekiʻe: ʻO ka Maʻemaʻe ≥ 99.5% e hōʻoia i ka hana paʻa o ka hopena a hoʻemi i nā huahana ʻaoʻao i ka hana ma hope.

Kūlana Mau: ʻO ka kaohi pono o ka maikaʻi ma o ke kaʻina hana (mai ke koho ʻana i nā mea maka a hiki i ka nānā ʻana i nā huahana i hoʻopau ʻia) e hōʻoiaʻiʻo ana i ke kūlike o ka pūʻulu.

Ka Hana Kūpono Loa: ʻO ka hana kūpono me nā diols, amines, a me nā monomers e hiki ai ke hoʻohui pono i nā huahana ma hope.

Hana Hana Aloha Kaiapuni: Hoʻohana i ka ʻenehana hana holomua me ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka hoʻopau liʻiliʻi, e kūlike ana me nā kūlana kaiapuni honua.

Ka Hoʻopili ʻana a me ka Mālama ʻana i ka Waikawa Maleic Anhydride

Pūʻolo: 25kg kaumaha ʻupena no kēlā me kēia ʻeke pepa kraft (me ka liner polyethylene o loko) a i ʻole 1000kg mau ʻeke jumbo, kūpono no ka halihali kai a me ka ʻāina.

Mālama: E mālama i loko o kahi hale kūʻai anuanu, maloʻo, a me ka ea maikaʻi, kahi mamao aku mai nā kumu wela, nā lapalapa ahi, a me nā mea hoʻoheheʻe ikaika. E pale i ka omo ʻana o ka makū (hiki ke hydrolyze i maleic acid) a me ka lā pololei. Ola papa: 12 mahina ma lalo o nā kūlana mālama kūpono.

Ka Palekana a me ka lawelawe ʻana o Cis-Butenedioic Anhydride

Palekana Pilikino: E ʻaʻahu i nā mīkina lima pale kemika, nā maka aniani, a me kahi pale lepo i ka wā e lawelawe ai. E pale i ka pili pololei ʻana me ka ʻili, nā maka, a me ke ala hanu.

Kōkua Mua: Inā pili ka ʻili, e holoi koke me ka wai nui no 15 mau minuke; inā pili ka maka, e holoi me ka wai a e ʻimi i ke kōkua lapaʻau. Inā hanu ʻia, e neʻe i ka ea hou a nīnau i ke kauka.

Ka lawelawe ʻana i ka ninini ʻana: E omo i nā mea i ninini ʻia me nā mea hoʻomomona inert (e laʻa, ke one, vermiculite), e hōʻiliʻili i loko o nā pahu i hoʻopaʻa ʻia, a e hoʻolei aku e like me nā lula kaiapuni kūloko. Mai hoʻolei i loko o nā kumu wai a i ʻole ka lepo.
