Umthengisi weSodium Hypophosphite Monohydrate eMzantsi Afrika

Yintoni iSodium Hypophosphite Monohydrate?

I-sodium hypophosphite monohydrate (NaH₂PO₂·H₂O) sisixhobo esimhlophe esiqinileyo esiqulathe i-phosphorus kwimeko ye-oxidation ye-+1, nto leyo eyenza ukuba ibe yiarhente yokunciphisa enamandla. Ukusetyenziswa kwayo okuphambili kwimizi-mveliso kukusetyenziswa njengearhente yokunciphisa kwiibhafu zeplating ze-nickel-phosphorus (EN) ezingena-electroless, apho inciphisa ii-ion ze-nickel zibe yintsimbi ngaphandle komsinga wombane wangaphandle. I-alloy ye-nickel-phosphorus eveliswayo inobunzima obubalaseleyo, ukumelana nokuguguleka, kunye neempawu zokukhusela ukugqwala ezenza i-nickel engena-electro ibe yenye yezona ngubo zisetyenziswa kakhulu kwimizi-mveliso.

I-Electroless Nickel Plating

Kwi-electroless nickel (EN) plating, i-sodium hypophosphite i-oxidised ibe yi-phosphite ngelixa ngaxeshanye inciphisa i-nickel(II) ion ibe yi-nickel metal, ibeka i-nickel-phosphorus alloy efanayo phantse kuyo nayiphi na i-substrate - kuquka iiplastiki, izinto ezidityanisiweyo, kunye nejometri ezintsonkothileyo - ngaphandle kwesidingo soqhagamshelwano lombane okanye ulawulo losasazo lwangoku. Umxholo we-phosphorus wediphozithi (ngesiqhelo yi-5–12%) ulawulwa bubume bokuhlamba kwaye umisela ubunzima be-coating, iimpawu zemagnethi, kunye nokumelana nokugqwala. Ii-EN coatings zisetyenziswa kwicandelo leoyile negesi, iimoto, i-aerospace, kunye ne-elektroniki.

Iarhente yokunciphisa kwi-Chemical Synthesis

Njenge-arhente yokunciphisa ethambileyo nekhethayo, i-sodium hypophosphite inciphisa iityuwa ze-diazonium kwi-arenes (iimpendulo zohlobo lweBalz-Schiemann kunye ne-P(I) njenge-reductant) kwaye inciphisa iityuwa ezithile zesinyithi kwimeko yazo yesinyithi ngeenjongo zokutsala okanye zokuhombisa. Isetyenziswa ekuhlanganisweni kweekhemikhali zezinto ezithintela ilangatye, iikhompawundi ze-phosphorus ezikhethekileyo, kunye namayeza athile. Kwishishini lokutya, i-sodium hypophosphite yodidi lobuchwephesha isetyenziswa kwezinye iindlela ze-antioxidant, kwaye isetyenziswa ekuvelisweni kwe-hypophosphorous acid.

Izicelo ze-Flame Retardant Precursor kunye nezeMizi-mveliso

I-sodium hypophosphite kunye neetyuwa ze-hypophosphite ezinxulumene nazo zizinto ezibangela ukuba i-organophosphorus flame retardants isetyenziswa kwiipolymers zobunjineli, ngakumbi iiplastiki zobunjineli ezisekwe kwi-nylon kunye ne-polyester. I-hypophosphite chemistry inika i-phosphorus ngendlela esabelayo, engeyiyo i-halogenated edityaniswe kwi-polymer matrix. Ikwasetyenziswa ekufakeni i-electroplating ye-palladium, i-cobalt, kunye nezinye iintsimbi ngeendlela ezingena-electroless, kunye nasekuveliseni i-phosphinic acid derivatives kwizicelo zezolimo kunye nezamayeza.
