Sulfamic acid 5329-14-6
Aminosulfonic acid yog ib hom kua qaub khov uas tsis muaj xim, tsis muaj ntxhiab, thiab tsis muaj tshuaj lom. Nws cov kua dej muaj cov yam ntxwv ntawm cov kua qaub zoo ib yam li hydrochloric acid thiab sulfuric acid, tab sis nws cov tshuaj lom rau cov hlau qis dua li hydrochloric acid. Nws muaj tshuaj lom tsawg heev rau tib neeg lub cev, tab sis nws tsis tuaj yeem kov daim tawv nqaij ntev, tsis txhob hais txog kev nkag mus rau hauv qhov muag.
| Qhov tsos | Cov siv lead ua dawb los yog tsis muaj xim |
| Feem pua ntawm NH2SO3H% | ≥99.5 |

| Feem pua ntawm cov khoom tsis yaj hauv dej% | ≤0.02 |
| Feem pua ntawm Fe% | ≤0.005 |
| Feem pua loj ntawm kev poob ntawm qhov ziab% | ≤0.1 |
| Feem pua loj ntawm cov hlau hnyav (raws li Pb)% | ≤0.001 |
1. Cov kua dej aminosulfonic acid muaj cov nyhuv qeeb rau cov khoom xeb ntawm hlau. Qee cov sodium chloride tuaj yeem ntxiv rau kom maj mam tsim cov hydrochloric acid, yog li ua kom cov hlau yaj tau zoo.
2. Nws yog qhov tsim nyog rau kev tshem tawm cov nplai thiab cov khoom xeb ntawm qhov chaw ntawm cov khoom siv ua los ntawm hlau, hlau, tooj liab, stainless hlau thiab lwm yam ntaub ntawv.
3. Cov kua qaub aminosulfonic acid yog tib cov kua qaub uas siv tau los ntxuav cov hlau galvanized. Feem ntau, qhov kub ntawm kev ntxuav yog tswj tsis pub tshaj 66°C (kom tiv thaiv kev lwj ntawm aminosulfonic acid) thiab qhov concentration tsis pub tshaj 10%.
4. Aminosulfonic acid siv tau ua ib qho kev siv tshuaj rau kev titration acid-base hauv kev tshuaj xyuas chemistry.
5. Nws yog siv los ua tshuaj tua kab, hluav taws kub, tshuaj mos rau ntawv thiab textiles, shrink-proof, bleaching, softener rau fibers, thiab ntxuav rau hlau thiab ceramics.
6. Nws kuj tseem siv rau diazotization ntawm dyes thiab pickling ntawm electroplated hlau.
