Diethylenetriaminepentaacetic acid CAS: 67-43-6
Hoʻolauna huahana
ʻO ka waikona diethylenetriaminepentacetic (DTPA), i kapa ʻia ʻo diethylenetriaminepentacetic acid, he mea hoʻohui paʻakikī aminocarboxylic maikaʻi loa me nā waiwai chelating ikaika. ʻOi aku ka maikaʻi o ka paʻakikī me ka nui o nā cations ma mua o ka waika ethylenediaminetetraacetic. Pono ka chelate pili.
ʻO kēia huahana he aniani keʻokeʻo a i ʻole ka pauka crystalline. Ka helu heheʻe 230 ℃ (decomposition), hiki ke hoʻoheheʻe ʻia i ka wai wela a me ka hopena alkali, hiki ke hoʻoheheʻe ʻia i ka wai anuanu, hiki ʻole ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me nā eter alkohol.
Kahua noi
Ma ke ʻano he ʻoihana chelating kiʻekiʻe, hiki ke hoʻohana ʻia ka diethylene triamine pentaacetic acid i nā mea pale kala i ka hana ʻana i ka fiber acrylic, ʻoihana pepa, nā mea hoʻomaʻemaʻe wai, nā mea kōkua textile, chelating titrants, kiʻi kala a me nā ʻoihana meaʻai. Hoʻohana ʻia ia i ka lāʻau lapaʻau, nā mea ʻāina ʻokoʻa.

ʻO MIT-IVY INDUSTRY CO., LTD he mea hana a me ka mea hoʻopuka i nā mea pena kemika maikaʻi a me nā mea waena lāʻau lapaʻau ma Kina.
Hana nui i nā huahana aniline a me nā huahana chlorine series.
MIT –IVY Chemicals Industry Co., Ltd. He mea hana nui ia no 21 mau makahiki me nā lako hana piha a me ka mālama pono a me ka mālama ʻana i nā mīkini.
Hoʻohana mākou i ka ʻenehana hana kiʻekiʻe a me nā ʻano hoʻāʻo e ʻike ai i ka hana, ka hoʻomalu ʻana i ka maikaʻi e hoʻokō i ka maʻamau. Ua ʻae ʻia mākou e SGS, ISO9001, ISO140 01, GB/HS16949 a me T28001.
ʻO nā huahana nui ʻo Mit-Ivy e like me kēia:
API, nā lāʻau lapaʻau waena, Dye intermediates, maikaʻi, nā kemika kūikawā, Waterborne industry pena a me nā mea ikehu hou.
ʻO kā mākou mau mākeke nui ʻo ʻAmelika, India, ʻApelika, Indonesia, Turkey, Hema-hikina Asia, West Asia a pēlā aku. ʻO MIT-IVY Industry ʻO nā huahana nui kaʻana i ka 97% o ka mākeke kūloko kūikawā i ka hana a me ka hoʻokele, hiki iā mākou ke hoʻolako i nā huahana me ka uku hoʻokūkū. me ka maikaʻi maikaʻi a me ke kumukūʻai a hoʻokipa ʻia e kūkākūkā. Loaʻa i kā mākou ʻoihana nā poʻe loea i mea nui i ka R&D chemical a me ka hoʻokele sicentific, hoʻolako i nā huahana kemika maikaʻi me ke kūlana kiʻekiʻe a me ka lawelawe kokoke, hoʻolako pū i nā huahana kuʻuna e like me ka koi o kā mākou mea kūʻai aku. Loaʻa iā mākou kahi hui hana hoʻokele maikaʻi a hoʻoikaika iā mākou iho me kahi kuʻuna maʻamau, mālama a me ka hoʻokō ma o ka hui pū ʻana, hoʻoikaika kā mākou hui e hoʻokō i ka kūleʻa i ka leʻaleʻa i kā mākou mea kūʻai aku a iā mākou iho. Ke hoʻomau nei mākou i kā mākou huahana a hoʻomaikaʻi i kā mākou lawelawe, ʻoihana kūʻai. No laila, hoʻomaka mākou i ke ʻano kūʻai mua ma ka ʻupena ma Kina, ʻo ia ke kālepa kūʻai o nā pūʻolo liʻiliʻi e lawe pū mai i nā ʻano hoʻokele like ʻole.
