Sulfamic acid 5329-14-6
Aminosulfonic acid yog xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom neeg muaj zog acid. Nws cov tshuaj aqueous muaj tib lub zog acid zog xws li hydrochloric acid thiab sulfuric acid, tab sis nws cov corrosiveness rau hlau yog qis dua li ntawm hydrochloric acid. Nws muaj toxicity tsawg heev rau tib neeg lub cev, tab sis nws tsis tuaj yeem nyob rau hauv kev sib cuag nrog daim tawv nqaij ntev, cia nyob ib leeg nkag mus rau qhov muag.
| Qhov tshwm sim | Tsis muaj xim los yog dawb crystals |
| Loj feem ntawm NH2SO3H% | ≥99.5 |
| Loj feem ntawm sulfate (as SO42-)% | ≤ 0.05 |
| Loj feem ntawm insoluble teeb meem hauv dej% | ≤ 0.02 |
| Feem ntau ntawm Fe% | ≤ 0.005 |
| Loj feem poob ntawm drying% | ≤0.1 |
| Loj feem Cov hlau hnyav (raws li Pb)% | ≤ 0.001 |
1. Aminosulfonic acid aqueous kua muaj qhov cuam tshuam qeeb ntawm cov khoom siv corrosion ntawm hlau. Qee cov tshuaj sodium chloride tuaj yeem muab ntxiv kom maj mam tsim cov tshuaj hydrochloric acid, yog li ua kom cov nplai hlau ua kom zoo.
2. Nws yog qhov tsim nyog rau kev tshem tawm cov nplai thiab cov khoom siv corrosion ntawm cov khoom siv ua los ntawm hlau, hlau, tooj liab, stainless hlau thiab lwm yam ntaub ntawv.
3. Aminosulfonic acid aqueous tov yog cov kua qaub nkaus xwb uas tuaj yeem siv los ntxuav cov hlau galvanized. Kev ntxuav kub yog feem ntau tswj tsis pub tshaj 66 ° C (kom tiv thaiv kom tsis txhob decomposition ntawm aminosulfonic acid) thiab cov concentration tsis tshaj 10%.
4.Aminosulfonic acid tuaj yeem siv los ua cov ntaub ntawv siv rau cov kua qaub-piv titration hauv kev tshuaj ntsuam chemistry.
5.Nws yog siv los ua tshuaj tua kab mob, hluav taws kub retardant, softener rau ntawv thiab textiles, shrink-proof, bleaching, softener rau fibers, thiab ntxuav rau hlau thiab ceramics.
6.Nws kuj yog siv rau diazotization ntawm dyes thiab pickling ntawm electroplated hlau.
