Maʻemaʻe kiʻekiʻe 3N cas 7782-49-2 Selenium pauka
ʻIke kumu:
1.Molecular formula: Se
2.Molecular kaumaha: 78.96
3.Storage: E kūʻai i loko o kahi hale kūʻai maloʻo, ventilated a maloʻo.Pale i ka makū a me ka ʻike.
4.Packing: Pono e hoʻohana ʻia kēia huahana i loko o ʻeono mahina, a e ʻoluʻolu e hoʻihoʻi i nā koena i loko o ka pōʻai ʻōpala.
Nā wehewehe:
● He mea kemika ka Selenium me ka hōʻailona Se a me ka helu ʻātoma 34 a loaʻa i ka haumia i loko o nā mea metala sulfide.
● Loaʻa iā Selenium nā isotopes kūlohelohe ʻeono.ʻO ka Selenium ʻeleʻele kahi paʻa ʻulaʻula a hiki ke hoʻoheheʻe ʻia ma CS2.
● Kūikawā i ka hana ʻana i ka selenium maʻemaʻe kiʻekiʻe me ka liʻiliʻi liʻiliʻi o ka nui o ka palaoa.

Noi:
1. Loaʻa i ka Selenium nā waiwai photovoltaic a me ka photoconductive maikaʻi, a hoʻohana nui ʻia i nā mea uila, e like me nā photocells, nā mika māmā a me nā cell solar.
2. ʻO ka lua o ka hoʻohana nui ʻana o ka selenium ma ka ʻoihana aniani: hoʻohana ʻia ka selenium e wehe i ke kala mai ke aniani, e hāʻawi i ka ʻulaʻula i nā aniani a me nā enamels.
3. ʻO ke kolu o ka hoʻohana ʻana, e lawe ana ma kahi o 15% ka sodium selenite no nā meaʻai holoholona a me nā meaʻai.
4. Hiki i ka Selenium ke loaʻa nā noi i ke kope kope ʻana, i ke kani ʻana o nā kiʻi.ʻO kāna hoʻohana noʻeau e hoʻoikaika a hoʻonui i ke ʻano tonal o nā kiʻi kiʻi ʻeleʻele a keʻokeʻo.
5. Aia nā mea hoʻohana ʻē aʻe o ka selenium i loko o nā ʻāpana metala e like me nā papa alakaʻi i hoʻohana ʻia i loko o nā pahu waihona a me nā mea hoʻoponopono e hoʻololi i ka mana AC i ka manawa DC.
6. Hoʻohana ʻia ʻo Selenium e hoʻomaikaʻi i ke kūpaʻa abrasion i nā rubbers vulcanized.Hoʻohui ʻia kekahi mau pūhui selenium i nā shampoos anti-dandruff.
Palapala
Ua ʻae ʻia nā huahana e FDA, REACH, ROSH, ISO a me nā palapala hōʻoia ʻē aʻe, e like me nā kūlana aupuni.

FAQ:
Nīnau: He ʻoihana kālepa ʻoe a mea hana paha?
A: He hale hana mākou.
Q: Pehea ka lōʻihi o kāu manawa hoʻouna?
A: ʻO ka maʻamau he 5-10 mau lā inā loaʻa nā waiwai.a i ʻole he 15-20 mau lā inā ʻaʻole i loaʻa nā waiwai, e like me ka nui.
Q: Hāʻawi anei ʻoe i nā laʻana?He manuahi a keu paha ?
A: ʻAe, hiki iā mākou ke hāʻawi i ka hāpana no ka uku manuahi akā ʻaʻole e uku i ke kumukūʻai o ka ukana.
Q: He aha kāu mau ʻōlelo uku?
A: Uku<=1000USD, 100% ma mua.Uku>= 1000USD, 30% T / T ma mua, kaulike ma mua o ka hoʻouna ʻana.
