Hoʻolauna

ʻIke ʻia ʻo Solvent Yellow 44 ʻo Sudan Yellow G ma kemika, a ʻo kona ʻano kemika he chromate o Sudan Yellow G. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana.

 

ʻAno maikaʻi:

- Ke ʻano: Solvent Yellow 44 he pauka crystalline mai ka ʻalani-melemele a ʻulaʻula-melemele.

- Solubility: hiki ke hoʻoheheʻe ʻia i ka wai, methanol, ethanol, insoluble i ka ether, benzene a me nā mea hoʻoheheʻe ʻē aʻe.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia nā mea pena kemika: hiki ke hoʻohana ʻia ka solvent melemele 44 ma ke ʻano he pena i nā mea pena a me ka hoʻopaʻa inoa ʻana.

 

Hanana:

Hoʻomākaukau nui ʻia ka mea hoʻoheheʻe melemele 44 e ka hopena o ka sodium chromate me Sudan melemele G i loko o ka wai wai.

 

ʻIke palekana:

- ʻO Solvent Yellow 44 he mea pena kemika a pono e mālama pono ʻia e pale aku i ka hanu ʻana i ka lepo a i ʻole ka pili ʻana me ka ʻili, nā maka, a pēlā aku.

- E hoʻohana i nā mea pale pilikino kūpono e like me nā mīkina lima, nā aniani, a me nā lole pale i ka wā e hoʻohana ai.

- Inā pili ka ʻili a i ʻole ka ʻili, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.

- I ka wā o ka mālama ʻana, pono e waiho ʻia ka solvent melemele 44 i kahi maloʻo, ʻoluʻolu a maikaʻi ka makani e pale aku ai i ka hoʻopili ʻana me ka ʻāʻī, nā mea ʻokiʻekiʻe a i ʻole nā ​​​​mea hana ʻē aʻe.

 

Ma ka laulā, pono e hoʻohana ʻia ka hoʻohana ʻana i ka solvent yellow 44 e like me nā kaʻina hana palekana a e like me ka wahi noi kikoʻī a me nā koi hoʻoponopono.
