Nā hoʻohana o ka Maleic Anhydride

He mea maka kemika organik koʻikoʻi ka maleic anhydride me nā ʻano hana like ʻole ma nā ʻoihana he nui. ʻO kāna mau hoʻohana nui penei:

1. Hana ʻana i nā mea Polymer

ʻO nā Resins Polyester Unsaturated (UPR): ʻO kēia ke kahua noi nui loa o ka maleic anhydride. Hoʻopili ʻo MA me nā diols (e like me ka ethylene glycol, propylene glycol) e hana i nā resins polyester unsaturated. Hoʻohana nui ʻia kēia mau resins i ka hana ʻana o nā plastics i hoʻoikaika ʻia e ka fiberglass (FRP), kahi e loaʻa ai nā noi i nā waʻa, nā ʻāpana kaʻa, nā lako kemika, a me nā mea kūkulu hale ma muli o ko lākou ikaika kiʻekiʻe, ke kūpaʻa i ka pala, a me nā waiwai māmā.

Nā Resins Alkyd: Hoʻohana ʻia ka maleic anhydride i ka synthesis o nā resins alkyd, ʻo ia nā mea nui i nā pena hoʻonaninani, nā uhi ʻoihana, a me nā varnish. Hoʻomaikaʻi nā resins Alkyd i ka hoʻopili ʻana, ka ʻālohilohi, a me ke kūpaʻa o nā uhi.

Nā Polymers ʻē aʻe: Hiki ke copolymerized me nā monomers e like me ka styrene, vinyl acetate, a me nā acrylic esters e hana i nā copolymers. Hoʻohana ʻia kēia mau copolymers i nā mea hoʻopili, nā mea kōkua lole, a me nā mea hoʻololi plastic e hoʻomaikaʻi i ka hana huahana (e laʻa, ke kūpaʻa wela, ka maʻalahi).

2. Nā Kemika Waena

Hana ʻana o nā ʻakika Organic: Hoʻopili ʻia ka Cis-Butenedioic Anhydride i ka hydrolysis e hana i ka maleic acid, a hiki i ka hydrogenation hou ke hana i ka succinic acid a i ʻole tetrahydrophthalic anhydride. He mau mea waena koʻikoʻi kēia mau huahana no ka synthesis o nā lāʻau lapaʻau, nā pesticides, a me nā surfactants.

Hana ʻana o nā Pesticides: ʻO ka Maleic Anhydride Acid kahi mea maka no ka hana ʻana i kekahi mau pesticides, e like me nā herbicides (e laʻa, glyphosate intermediates) a me nā insecticides, e kōkua ana i ka kaohi ʻana i nā pest i ka hana mahiʻai.

Nā Hana Kūikawā Lāʻau Lapaʻau: Hoʻohana ʻia ka Maleic Acid Anhydride i ka synthesis o kekahi mau mea lāʻau lapaʻau, e like me nā lāʻau anti-inflammatory a me nā huaora, e pāʻani ana i kahi hana koʻikoʻi i ka ʻoihana lāʻau lapaʻau.

3. Nā ʻoihana pepa a me ka lole

Mea Hoʻonui Pepa: Hoʻohana ʻia nā copolymers maleic anhydride ma ke ʻano he mau mea hoʻonui kūloko no ka pepa. Hiki iā lākou ke hoʻomaikaʻi i ke kūpaʻa wai a me ka hiki ke paʻi ʻia o ka pepa, e kūpono ai no ka pepa ʻōwili, ka pepa moʻomeheu, a me nā ʻano pepa ʻē aʻe.

Nā Mea Kōkua i ka Loli: Hoʻohana ʻia ʻo 2 5-Furandine e hana i nā mea hoʻopau lole, e like me nā mea pale i ka crease a me nā mea pale i ka shrink. Hiki i kēia mau mea ke hoʻonui i ka hiki ke komo a me ke kūpaʻa o nā lole, ʻoi aku hoʻi no nā lole pulupulu a me polyester.

4. ʻOihana ʻAila a me ke Kinoea

Mea Hoʻopau i ka ʻAi ʻAi: Hoʻohana ʻia nā mea hana maleic anhydride (e laʻa, maleic anhydride-vinylpyrrolidone copolymers) ma ke ʻano he mea hoʻopau i ka ʻai ʻana i ka wai o ka ʻaila a me nā paipu aila a me ke kinoea. Hiki iā lākou ke hana i kahi ʻili pale ma luna o ka ʻili metala, e hōʻemi ana i ka ʻai ʻana i hoʻokumu ʻia e ka wai a me nā mea ʻai ʻino.

Mea Hoʻōki Unahi: Hoʻohana pū ʻia ʻo Cis-Butenedioic Anhydrides Maleic Anhydride i ka hoʻomākaukau ʻana i nā mea hoʻōki unahi, ka mea e pale ai i ka hoʻokumu ʻia ʻana o ka unahi (e like me ka calcium carbonate, calcium sulfate) i nā lako hana ʻaila a me nā pipeline, e hōʻoiaʻiʻo ana i ka hana maʻalahi o ka hana ʻana.

5. Nā Hana ʻē aʻe

Nā Mea Hoʻohui Meaʻai: Hoʻohana ʻia kekahi mau mea hoʻohui maleic anhydride (e laʻa, ka waikawa succinic, i hana ʻia mai ka maleic anhydride) ma ke ʻano he mau mea hoʻohui meaʻai, e like me nā acidulants a me nā mea hoʻonui ʻono, i ka ʻoihana meaʻai.

Nā Mea Hoʻohui Lubricant: Hoʻohana ʻia nā Maleic Anhydride Flakes e synthesize i nā mea hoʻohui lubricant, e like me nā mea hoʻolaha a me nā antioxidants, hiki ke hoʻomaikaʻi i ka hana a me ke ola lawelawe o nā aila lubricating.
