Nānā Huahana

ʻO ka Phthalic Anhydride (PA) he mea koʻikoʻi koʻikoʻi koʻikoʻi, i hana mua ʻia e ka oxidation o ortho-xylene a i ʻole naphthalene. ʻIke ʻia ʻo ia ma ke ʻano he paʻa keʻokeʻo keʻokeʻo me kahi ʻala hoʻonāukiuki. Hoʻohana nui ʻia ʻo PA i ka hana ʻana i nā plasticizers, unsaturated polyester resins, alkyd resins, dyes, a me nā puaʻa, e lilo ia i mea koʻikoʻi i waena o ka ʻoihana kemika.

Nā mea nui

• Kiʻekiʻe Reactivity:Loaʻa i ka PA nā pūʻulu anhydride, e hana maʻalahi me nā waiʻona, nā amine, a me nā pūhui ʻē aʻe e hana i nā esters a i ʻole amides.
• Maikaʻi Solubility:Hiki ke hoʻoheheʻe ʻia i loko o ka wai wela, nā waiʻona, nā ethers, a me nā mea hoʻoheheʻe organik ʻē aʻe.
• Paʻa:Paʻa ma lalo o nā kūlana maloʻo akā hydrolyze mālie i ka waika phthalic i mua o ka wai.
• ʻAno kūpono:Hoʻohana ʻia i ka synthesis o kahi ākea o nā huahana kemika, e hoʻohana nui ʻia.

Nā noi

1. Nā mea hoʻopalapala:Hoʻohana ʻia e hana i nā esters phthalate (eg, DOP, DBP), i hoʻohana nui ʻia i nā huahana PVC e hoʻomaikaʻi i ka maʻalahi a me ke kaʻina hana.
2. Palena Polyester Unsaturated:Hoʻohana ʻia i ka hana ʻana i nā fiberglass, nā uhi, a me nā mea hoʻopili, e hāʻawi ana i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa kemika.
3. Alkyd Resins:Hoʻohana ʻia i loko o nā pena, nā uhi, a me nā varnish, e hāʻawi ana i ka adhesion maikaʻi a me ka nani.
4. Nā Wai a me nā Pigments:Hana ia ma ke ʻano he waena i ka synthesis o nā mea hoʻonaninani anthraquinone a me nā puaʻa.
5. Nā noi ʻē aʻe:Hoʻohana ʻia i ka hana ʻana i nā intermediates pharmaceutical, pesticides, a me nā mea ʻala.

Puke a me ka waiho ʻana

• Packaging:Loaʻa ma 25 kg / ʻeke, 500 kg / ʻeke, a i ʻole ʻeke ʻeke. Loaʻa nā koho paʻi maʻamau ma ke noi.
• Waihona:E mālama i loko o kahi anuanu, maloʻo, a maikaʻi ka makani. Hōʻalo i ka pili ʻana me ka wai. Manaʻo ʻia ka mahana mālama: 15-25 ℃.

Nā Manaʻo Palekana & Kaiapuni

• Huhū:He mea hoʻonāukiuki ka PA i ka ʻili, nā maka, a me ka ʻōnaehana hanu. Pono e ʻaʻahu ʻia nā mea pale kūpono (e laʻa, nā mīkina lima, nā maka aniani, nā respirator) i ka wā e lawelawe ai.
• Hiki i ke ahi:Hiki ke puhi ʻia akā ʻaʻole hiki ke wela loa. E mālama i nā lapalapa ahi a me nā wela kiʻekiʻe.
• Ka hopena o ke kaiapuni:E hoʻolei i nā mea ʻōpala e like me nā lula kaiapuni kūloko e pale ai i ka haumia.

Kāhea iā mā˚ou

No ka 'ike hou aku a i 'ole e noi i kekahi la'ana, e 'olu'olu e leka uila i kā mākou hui kū'ai. Kūpaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe a me ka lawelawe maikaʻi loa!
