ʻIke Huahana

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

Nā Hiʻohiʻona Koʻikoʻi

• Ka Hana Kiʻekiʻe:Loaʻa iā PA nā hui anhydride, ka mea e pane maʻalahi me nā alcohols, amines, a me nā hui ʻē aʻe e hana i nā esters a i ʻole amides.
• Ka hoʻoheheʻe maikaʻi: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 hydrolyzes mālie i ka waikawa phthalic i ke alo o ka wai.
• Ka maʻalahi:Hoʻohana nui ʻia no ka hana ʻana i nā ʻano huahana kemika like ʻole, he mea ia e hoʻolilo ai i mea maʻalahi loa.

Nā noi

1. Nā mea hoʻopili palakiko:Hoʻohana ʻia e hana i nā esters phthalate (e laʻa, DOP, DBP), i hoʻohana nui ʻia i nā huahana PVC e hoʻonui i ka maʻalahi a me ka hiki ke hana.
2. Nā Resina Polyester i hoʻopiha ʻole ʻia:Hoʻohana ʻia i ka hana ʻana o ka fiberglass, nā uhi, a me nā mea hoʻopili, e hāʻawi ana i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa kemika.
3. Nā Resina Alkyd:Hoʻohana ʻia i nā pena, nā uhi, a me nā varnish, e hāʻawi ana i ka hoʻopili maikaʻi a me ka ʻālohilohi.
4. Nā Waihoʻoluʻu a me nā Pigments:Lawelawe ma ke ʻano he waena i ka synthesis o nā dyes a me nā pigments anthraquinone.
5. Nā Hana ʻē aʻe:Hoʻohana ʻia i ka hana ʻana o nā mea lapaʻau, nā pesticides, a me nā mea ʻala.

ʻŌmole a me ka Mālama ʻana

• Pūʻolo:Loaʻa i loko o 25 kg/ʻeke, 500 kg/ʻeke, a i ʻole nā ​​ʻeke tona. Loaʻa nā koho hoʻopili maʻamau ma ke noi.
• Ka mālama ʻana:E mālama i kahi anu, maloʻo, a me kahi ea maikaʻi. E pale i ka pili ʻana me ka makū. ʻO ka mahana mālama i manaʻo ʻia: 15-25℃.

Nā Manaʻo Palekana a me ke Kaiapuni

• Hoʻonāukiuki:He mea hoʻonāukiuki ka PA i ka ʻili, nā maka, a me ka ʻōnaehana hanu. Pono e ʻaʻahu i nā lako palekana kūpono (e laʻa me nā mīkina lima, nā maka aniani, nā mea hanu) i ka wā e lawelawe ai.
• Ka lapalapa ʻana:Hiki ke ʻā akā ʻaʻole hiki ke ʻā nui. E mālama aku mai nā lapalapa ahi a me nā mahana kiʻekiʻe.
• Ka hopena o ke kaiapuni:E hoʻolei i nā ʻōpala e like me nā lula kaiapuni kūloko e pale aku ai i ka haumia.

Kāhea iā mā˚ou

No ka ʻike hou aku a i ʻole e noi i kahi laʻana, e ʻoluʻolu e kelepona i kā mākou hui kūʻai aku. Ua kūpaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe a me ka lawelawe maikaʻi loa!
