Isodium sulfate

Isodium sulfate, eyaziwa ngokuba yi-sodium persulfate, i-inorganic compound, i-chemical formula Na2S2O8, i-white crystalline powder, i-soluble emanzini, i-insoluble kwi-ethanol, isetyenziswa kakhulu njenge-bleach, i-oxidant, i-emulsion polymerization accelerator.

Iinkcazelo ngeempawu:Ikristale emhlophe okanye i-crystalline powder.Akukho vumba.Ayinancasa.Ifomula yemolekyuli Na2S2O8, ubunzima bemolekyuli 238.13.Ichithwa ngokuthe ngcembe kwiqondo lokushisa, kwaye inokuchithwa ngokukhawuleza ngokufudumeza okanye kwi-ethanol, emva koko i-oksijini ikhutshwe kwaye i-sodium pyrosulfate yenziwe.Ubumanzi kunye neplatinam emnyama, isilivere, ilothe, isinyithi, i-iron, i-magnesium, i-nickel, i-manganese kunye nezinye i-ion zetsimbi okanye i-alloys yazo inokukhuthaza ukubola, ubushushu obuphezulu (malunga ne-200℃) ukubola ngokukhawuleza, ukukhulula i-hydrogen peroxide.Inyibilika emanzini (70.4 ku-20℃).I-oxidizing kakhulu.Ukucaphuka okunamandla kwesikhumba, ukudibana kwexesha elide nolusu, kunokubangela ukungezwani komzimba, kufuneka ubeke ingqalelo ekusebenzeni.Impuku transoral LD50895mg/kg.Gcina ngokuqinileyo.Ilabhoratri ivelisa i-sodium persulfate ngokufudumeza isisombululo se-ammonium persulfate nge-caustic soda okanye i-sodium carbonate ukususa i-ammonia kunye ne-carbon dioxide.

I-agent eyomeleleyo ene-oxidizing:I-sodium persulfate ine-oxidation enamandla, ingasetyenziselwa njenge-agent e-oxidizing, i-oxidize i-Cr3 +, i-Mn2 +, njl njl kwi-oxidation state compounds ehambelanayo, xa kukho i-Ag +, inokukhuthaza ukusabela kwe-oxidation ngasentla;Ingasetyenziswa njenge-ejenti ye-bleaching, i-agent yonyango yesinyithi kunye ne-reagent yekhemikhali ngepropati yayo ye-oxidation.Imathiriyeli ekrwada yamayeza;Ii-accelerators kunye nabaqalisi bebhetri kunye ne-emulsion polymerization reactions.

Isicelo:Isodium persulfate ifumana ukusetyenziswa okubanzi njengebleach, oxidant, kunye neemulsion polymerization accelerator.Ukukwazi kwayo ukususa amabala kunye nokwenza amalaphu abe mhlophe kuyenze yaduma njengearhente yokuthambisa.Nokuba ngamabala ewayini anenkani kwihempe yakho oyithandayo okanye iilinen ezigudileyo, i-sodium persulfate inokujongana nale miba.

Ngapha koko, i-sodium persulfate ibonisa iipropathi ezinamandla ze-oxidizing.Oku kwenza kube yinto efanelekileyo yokuncedisa kwiikhemikhali ezifuna ukususwa kwee-electron.Kumashishini athembele kakhulu kwiinkqubo ze-oxidation, ezifana nokuveliswa kwamayeza kunye nedayi, i-sodium persulfate ibonakalisa ukuba yi-asethi engabalulekanga.

Ukongeza, le khompawundi ikwasebenza njengomgqugquzeli we-emulsion polymerization.Kwabo bangalaziyo eli gama, i-emulsion polymerization ibhekisa kwinkqubo yokwenziwa kweepolymers kwindawo enamanzi.I-sodium persulfate isebenza njenge-catalyst, inceda ekubunjweni kwezi polymers.Amashishini asebenzisa i-emulsion polymerization, efana ne-adhesives kunye ne-coatings, ixhomekeke kakhulu kwi-sodium persulfate ngokusebenza kwayo ekufezekiseni iziphumo ezifunwayo.

Ubume obunobuninzi be-sodium persulfate yinto eyenza ukuba ihluke kwezinye iikhompawundi.Ukukwazi kwayo ukusebenza njenge-agent ye-bleaching kunye ne-oxidant yenza kube yinto ekhangayo kuluhlu olubanzi lwamashishini.Ukongeza, i-emulsion polymerization yayo ekhuthaza iipropathi zandisa ngakumbi umda wosetyenziso.

Ngaphandle kokusetyenziswa kwayo ngeendlela ezahlukeneyo, i-sodium persulfate inezinye izinto ezininzi ezahlukileyo.Ukunyibilika kwayo emanzini kuphucula ukusebenza kwayo njenge-bleach kunye ne-oxidant, ukuyivumela ukuba inyibilike ngokukhawuleza kwaye idibanise nezinye izinto.Ngakolunye uhlangothi, ukunganyibiliki kwayo kwi-ethanol kuthintela ukuphazamisa iinkqubo ezixhomekeke kwi-ethanol njenge-solvent.

Ukuqinisekisa ukusetyenziswa ngokufanelekileyo kwe-sodium persulfate, kubalulekile ukuqwalasela izinto ezithile.Ukuphatha ngononophelo kunye nokubambelela kwizikhokelo zokhuseleko kubalulekile ngenxa yobume bayo obunokuba yingozi.Ngaphaya koko, idosi efanelekileyo ibalulekile xa ufaka i-sodium persulfate kuyo nayiphi na inkqubo, nokuba yibleaching, oxidation, okanye i-emulsion polymerization.

Iphakheji: 25kg / Isikhwama

Imiqathango yokusebenza:ukusebenza okuvaliweyo, ukuqinisa umoya.Abanini-zithuthi kufuneka baqeqeshwe ngokukodwa kwaye bathobele ngokungqongqo iinkqubo zokusebenza.Kuyacetyiswa ukuba abaqhubi banxibe isigqubuthelo sombane sohlobo lwesihluzi sokuphefumla sothuli, impahla ekhuselayo ye-polyethylene, kunye neeglavu zerabha.Zigcine kude nomlilo nobushushu.Akutshaywa emsebenzini.Kuphephe ukuvelisa uthuli.Gwema ukudibanisa nama-agent okunciphisa, i-powders yensimbi esebenzayo, i-alkali, i-alcohols.Xa uphatha, ukulayishwa okulula kunye nokuthululwa kufuneka kwenziwe ukuthintela umonakalo wokupakisha kunye nezikhongozeli.Musa ukothuka, impembelelo kunye nengxabano.Ixhotyiswe ngeentlobo ezihambelanayo kunye nobuninzi bezixhobo zomlilo kunye nokuvuza kwezixhobo zonyango olungxamisekileyo.Izikhongozeli ezingenanto zinokuba neentsalela eziyingozi.

Izilumkiso zokugcina:Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya.Zigcine kude nomlilo nobushushu.Ubushushu bendawo yokugcina amanzi abuyi kuba ngaphezu kwe-30 ℃, kwaye ukufuma okuhambelanayo akuyi kudlula i-80%.Iphakheji ivaliwe.Kufuneka igcinwe ngokwahlukileyo kwii-agent zokunciphisa, i-powders yensimbi esebenzayo, i-alkalis, i-alcohols, njl., kwaye akufanele ixutywe.Iindawo zokugcina kufuneka zixhotyiswe ngezixhobo ezifanelekileyo zokuqulatha ukuvuza.

Ukuqukumbela, i-sodium persulfate ihlala iyikhompawundi eguquguqukayo kwaye iyimfuneko.Ukusebenza kwayo njenge-bleach, i-oxidant, kunye ne-emulsion polymerization umgqugquzeli uyibeka kwimfuno ephezulu.Ngefomula yayo yeekhemikhali i-Na2S2O8, le powder emhlophe ye-crystalline iyaqhubeka isebenza indima ebalulekileyo kumashishini ahlukeneyo.Njengayo nayiphi na i-compound yekhemikhali, kubalulekile ukuphatha i-sodium persulfate ngononophelo kwaye ukhumbule idosi efanelekileyo.Ke, kwixesha elizayo xa uzifumana ufuna iblitshi ethembekileyo okanye i-oxidant, cinga ngokufikelela kwisodium persulfate, i-powerhouse compound engaze isilele ukuzisa iziphumo ezikhethekileyo.
