MF:C4H2O3
MW:98.06
ʻANO:
ʻO Maleic Anhydride (MAN) kahi hui organik me ke ʻano kemika C4H203. ʻO ia ka anhydride waikawa o ka waikawa maleic a i kona kūlana maʻemaʻe he mea paʻa ʻole ke kala a keʻokeʻo paha me kahi ʻala ʻawaʻawa. He mole kupaianaha maoli ka maleic anhydride no ka mea he ʻelua ʻano hana kemika e lilo ia i mea pono kūikawā i ka synthesis kemika a me nā noi.
He mea hana kemika multifunctional ʻo Maleic Anhydride me nā noi ma nā ʻano ʻoihana kemika like ʻole. ʻO kona hoʻohana nui ʻana ma ke ʻano he feedstock i ka hana ʻana o nā resins polyester unsaturated (UPR).
Hoʻohana ʻia kēia mau resins i nā noi i hoʻoikaika ʻia i ke aniani a me nā noi i hoʻoikaika ʻole ʻia. Hoʻokomo pū ka hoʻohana hope ʻana o ka UPR i nā ʻano noi like ʻole i ke kūkulu ʻana, nā ʻoihana moana a me nā kaʻa.

Hoʻohana
ʻO Maleic Anhydride kahi hui heterocyclic i hoʻohana ʻia i ka hana ʻana i nā resins polyester unsaturated. Loaʻa iā ia kahi ākea o nā noi ʻē aʻe; hoʻohana ʻia ia i nā tensides synthetic, insecticides, herbicides a me fungicides.
Hoʻohana ʻia ka maleic anhydride i nā syntheses Diels-Alder (ma ke ʻano he dienophile), hana ʻana i nā resins ʻano alkyd, nā mea hoʻohuihui kala, nā lāʻau lapaʻau, nā kemika mahiʻai (maleic hydrazide, malathion), i nā hopena copolymerization.
ʻŌpala a me ka Hoʻouna ʻana
25KG/ʻeke a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
