Ammonium persulfate

Ammonium Persulfate (Aps), tseem hu ua Diamondmanium personodisulfate, yog cov tshuaj ammonium nrog cov tshuaj lom neeg thiab txoj kev molecular hnyav ntawm 228.201 g / mol.

Kev tshawb fawb qhia tau tias ammonium persulfate, ib tug oxidizing thiab tshuaj dawb siv rau hauv kev lag luam roj teeb, thiab raws li tus neeg saib xyuas kev tsim nyog hauv kev lag luam textile. Nws tseem siv rau kev kho cov hlau thiab semiconductor cov ntaub ntawv, etching hauv cov roj rho tawm, cov hmoov nplej thiab cov roj ntsha thiab rog thiab tshem cov hypo hauv kev yees duab.

1. Lub cev thiab tshuaj lom neeg
• Tseem Ceeb: Industrial-qib, cov ntsiab lus ≥ 95%.
• Pom kev: xim tsis muaju chij monoclinic, qee zaum ntsuab ntsuab, nrog hygroscopic zog.
• Tshuaj Xwm: Ammonium Persulffate yog ammonium ntsev ntawm potoxodisulfuric acid. Lub pectoxodisulfate ion muaj ib pab pawg peroxide thiab yog tus neeg sawv cev oxidizing muaj zog.
• Thermal decomposition: ntawm 120 ° C, nws decomposes, tso cov pa thiab sib sau pyrosulfates.
• Muaj peev xwm oxidizing muaj peev xwm: nws tuaj yeem oxidize mn²⁺ rau mnoos.
• Npaj: Ua kom tau los ntawm electrolyzing ammonium hydrogen sulfate aqueous aqueous.

Cov tsis tseem ceeb:
• Melting taw tes: 120 ° C (decomposes)
• BLATKING POINT: decomposes ua ntej boiling
• qhov ntom (dej = 1): 1.982
• Vapor ceev (huab cua = 1): 7.9
• solubility: yooj yim soluble hauv dej

Tshuaj lom neeg tshua:
• (NH₄) ₂s₂o₈ + 2H₂o ⇌ 2Nh₄H₄₄₄ + H₂o₂
• ionic sib npaug: (nh₄) ₂s₂o₈ ⇌ 2nh₄⁺ + s₂o₈²⁻
• S₂o₈²⁻ + 2H₂o ⇌ 2hso₄⁻ + h₂o₂
• HOPS₄⁻ ⇌ H⁺ + So₄²⁻

Kev daws yog kua qaub vim yog hydrolysis, thiab ntxiv nitric acid tuaj yeem inhibit rau pem hauv ntej cov tshuaj tiv thaiv.

2. Cov ntawv thov tseem ceeb
• Kev tshawb nrhiav ananciser: siv rau kev kuaj pom thiab txiav txim siab ntawm manganese ua tus neeg saib xyuas oxidizing.
• Tshuaj dawb tshuaj rau tus neeg saib xyuas: feem ntau siv hauv kev lag luam textile thiab xab npum.
• Kev yees duab: siv ua tus reducer thiab retarder.
• Kev Lag Luam Hluav Taws Xob: Ua raws li tus depolerizer.
• Polymerization pib ua ntej: Siv nyob rau hauv emulsion polymerization ntawm vinyl acetate, acrylates, thiab lwm tus monomers. Nws yog tus nqi-ua tau zoo thiab tsim cov dej-resistant emulsions.
• Tus neeg saib xyuas tus kheej: siv nyob rau hauv kev kho cov txheej txheem urea-formaldehyde, muab tus nqi kho mob sai tshaj plaws.
• Adhesive Addutive: Txhim kho cov nplaum zoo ntawm cov hmoov txhuv nplej siab los ntawm kev rov ua kom muaj cov protein. Pom zoo ntau npaum li cas: 0.2% -0.4% ntawm cov ntsiab lus STARCH.
• Nto Kho: Ua raws li tus neeg sawv cev kev kho mob hlau, tshwj xeeb tshaj yog rau cov chaw tooj liab.
• Kev lag luam tshuaj lom neeg: siv rau hauv kev tsim khoom ntawm cov persulfates thiab hydrogen peroxide.
• Kev lag luam roj av: siv hauv cov roj extraction thiab hydraulic fracturing.
• Kev lag luam khoom noj: ua haujlwm raws li cov khoom sau ua ke thiab cov pwm inhibitor rau ber poov xab.

3. Cov phom sij
• Cov Kev Nyab Xeeb: Chav Kawm Ntawv Teev Tseg 4.1 oxidizing cov khib nyiab
• Cov phom sij muaj mob:
• Ua rau voos thiab corrosion rau ntawm daim tawv nqaij thiab cov ntaub nyias nyias nyias.
• Inhalation tuaj yeem ua rau rhinitis, ua pa luv, thiab hnoos.
• Hu rau ntawm lub qhov muag thiab daim tawv yuav ua rau muaj kev txob txob hnyav, mob, thiab hlawv.
• Kev haus yuav ua rau mob plab, xeev siab, thiab ntuav.
• Hnov cov tawv nqaij raug mob yuav ua rau muaj kev mob siab rau Dermatitis.
• Hluav taws thiab tawg txaus ntshai: Txhawb kev sib txuas lus thiab tuaj yeem ua rau kub ntxhov thiab khaus rau kev tiv tauj.
• Kev ruaj khov: kuj nyob ruaj khov nyob rau hauv qis-siab cov kev daws tab sis yuav tsum tau saib xyuas thiab khaws cia.

Cia thiab tuav ceev faj:
• Khaws cia rau hauv qhov chaw txias, qhuav, kom deb ntawm kev tshav ntuj ncaj qha thiab ya raws.
• Zam kev sib cuag nrog cov khoom siv hluav taws xob thiab txo cov neeg sawv cev.
• Hnav cov khoom tiv thaiv tus kheej (PPE) thaum tuav.
• Txheeb xyuas cov tshuaj ua kom muaj kuab lom kom ntseeg tau tias muaj kev ruaj khov thiab tiv thaiv kev huam yuaj.

Ammonium persulfate yog ib qho tseem ceeb siv tshuaj reagent thoob plaws ntau yam lag luam, thiab tsim nyog tuav thiab so kom zoo rau kev nyab xeeb thiab kev ua tau zoo.
