    1. Loaʻa i ka Selenium nā waiwai photovoltaic a me ka photoconductive maikaʻi, a ua 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 kahi 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 iā 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 ka pale ʻana i ka abrasion i nā rubbers vulcanized.Hoʻohui ʻia kekahi mau pūhui selenium i nā shampoos anti-dandruff.

    FAQs

    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.
