1. Potassium iodide feem ntau yog siv los ua ib tug synergist rau steel pickling corrosion inhibitors los yog lwm yam corrosion inhibitors.Potassium iodide yog cov khoom siv raw rau kev npaj iodide thiab dyes.Nws yog siv los ua cov duab emulsifier, khoom noj khoom haus ntxiv, ua cov hnoos qeev, diuretic, tiv thaiv kab mob goiter thiab kev phais thyroid hyperfunction, thiab ua cov tshuaj analytical reagent.Nws yog siv los ua ib qho kev yees duab emulsifier hauv kev lag luam kev yees duab thiab tseem ua tshuaj thiab khoom noj khoom haus ntxiv.
2. Siv los ua khoom noj khoom haus.Raws li ib feem ntawm thyroxine, iodine koom nrog hauv cov metabolism hauv txhua yam hauv cov tsiaj nyeg thiab tswj cov cua sov hauv lub cev.Iodine yog ib qho tshuaj hormones tseem ceeb rau kev loj hlob, kev loj hlob thiab lactation ntawm cov tsiaj nyeg thiab nqaij qaib.Nws tuaj yeem txhim kho kev loj hlob ntawm cov tsiaj nyeg thiab nqaij qaib thiab txhawb kev noj qab haus huv ntawm lub cev.Yog hais tias lub cev ntawm cov tsiaj nyeg tsis muaj iodine, nws yuav ua rau cov kab mob metabolic, ua rau lub cev tsis zoo, cov thyroid o, cuam tshuam rau cov paj hlwb thiab cov xim ntawm lub tsho loj thiab kev zom thiab nqus ntawm cov khoom noj, nws thiaj li ua rau kev loj hlob qeeb.
3. Kev lag luam zaub mov yog siv los ua khoom noj khoom haus ntxiv (iodine enhancer).Kuj tseem siv tau los ua ib qho khoom noj ntxiv.
4. Siv raws li kev tshuaj ntsuam reagent, xws li kev npaj cov txheej txheem iodine raws li kev pabcuam reagent.Kuj tseem siv los ua ib qho photosensitive emulsifier, pub additive.Siv hauv kev lag luam kws tshuaj.
5. Potassium iodide yog co-solvent rau iodine thiab tej yam tsis zoo soluble hlau iodide.
6. Potassium iodide muaj ob daim ntawv thov tseem ceeb hauv kev kho saum npoo: ib qho yog rau kev tshuaj ntsuam xyuas tshuaj, qhov nruab nrab txo ntawm iodide ion thiab qee cov tshuaj tiv thaiv oxidative ion yog siv los tsim cov tshuaj iodine, thiab tom qab ntawd cov iodine txiav txim siab los xam cov concentration ntawm cov tshuaj ntsuam xyuas;Qhov thib ob yog rau cov complexation ntawm tej yam hlau ions, thiab nws raug siv raws li ib tug complexing neeg sawv cev rau cuprous thiab nyiaj nyob rau hauv electroplated tooj liab-silver alloys.
7. Lub npe hu ua iodized edible ntsev uas peb feem ntau noj yog ntxiv poov tshuaj iodide los yog poov tshuaj iodate (nyob rau hauv proportions rau 20,000) rau cov ntsev zoo tib yam (ntshiab sodium chloride).
8. Potassium iodide muaj qee qhov tshwj xeeb siv hauv kev kho mob dermatology.Nws cov txheej txheem ntawm kev ua haujlwm yog ib feem ntawm kev txhim kho kev tawg thiab kev zom ntawm cov ntaub so ntswg necrotic.Potassium iodide kuj muaj cov tshuaj tiv thaiv kab mob.Nws yog siv los kho sporotrichosis, pigmented blastomycosis, tsis tu ncua nodular erythema, thiab nodular vasculitis.Thaum siv cov poov tshuaj iodide, koj yuav tsum tau them sai sai rau nws cov kev mob tshwm sim.Nws tuaj yeem ua rau pustules, hlwv, erythema, eczema, urticaria, thiab lwm yam. Nws tuaj yeem ua rau pob txuv ntau dua, thiab tau kawg tuaj yeem ua rau plab zom mov thiab cov tsos mob ntawm mucosal.
9. Nws yog siv rau hauv cov tshuaj los tiv thaiv thiab kho cov kab mob goiter endemic thiab txhawb kev nqus thiab hnoos qeev ntawm vitreous opacity ntawm lub qhov muag.Nws kuj tseem siv tau los ua cov tshuaj analytical reagents, chromatography, thiab tsom xam qhov mob.
10. Potassium iodide kuj tuaj yeem ntsuas qhov ozone concentration, thiab hloov cov iodine los ua cov hmoov txhuv nplej siab.
