Sodium sulfate

Sodium sulfate, wotchedwanso sodium persulfate, ndi pawiri, mankhwala chilinganizo Na2S2O8, ndi woyera crystalline ufa, sungunuka m'madzi, insoluble mu Mowa, makamaka ntchito monga bulitchi, okosijeni, emulsion polymerization accelerator.

Katundu:White crystal kapena ufa wa crystalline.Palibe fungo.Zosakoma.Molecular formula Na2S2O8, molekyulu yolemera 238.13.Zimawonongeka pang'onopang'ono kutentha, ndipo zimatha kuwonongeka mofulumira ndi kutentha kapena mu ethanol, pambuyo pake mpweya umatulutsidwa ndipo sodium pyrosulfate imapangidwa.Chinyezi ndi platinamu wakuda, siliva, lead, chitsulo, mkuwa, magnesium, faifi tambala, manganese ndi ayoni zitsulo kapena ma aloyi awo amatha kulimbikitsa kuwonongeka, kutentha kwambiri (pafupifupi 200 ℃) kuwonongeka mwachangu, kumasula hydrogen peroxide.Zosungunuka m'madzi (70.4 pa 20 ℃).Ndi oxidizing kwambiri.Kupsa mtima kwamphamvu pakhungu, kukhudzana kwa nthawi yayitali ndi khungu, kungayambitse chifuwa, chiyenera kumvetsera ntchitoyo.Khoswe transoral LD50895mg/kg.Sungani mwamphamvu.Laboratory imapanga sodium sulfate potenthetsa yankho la ammonium sulfate ndi caustic soda kapena sodium carbonate kuchotsa ammonia ndi carbon dioxide.

Mphamvu ya okosijeni:Sodium persulfate ali ndi makutidwe ndi okosijeni amphamvu, angagwiritsidwe ntchito ngati wothandizila makutidwe ndi okosijeni, akhoza makutidwe ndi okosijeni Cr3+, Mn2+, etc. mu lolingana mkulu makutidwe ndi okosijeni boma mankhwala, pamene pali Ag +, akhoza kulimbikitsa makutidwe ndi okosijeni anachita pamwamba;Itha kugwiritsidwa ntchito ngati bleaching agent, chitsulo pamwamba chithandizo mankhwala ndi reagent mankhwala ndi makutidwe ndi okosijeni katundu.Zopangira mankhwala;Ma Accelerator ndi oyambitsa ma batire ndi emulsion polymerization reaction.

Kugwiritsa ntchito:Sodium persulfate imagwiritsa ntchito kwambiri ngati bleach, oxidant, ndi emulsion polymerization accelerator.Kutha kwake kuchotsa madontho ndi kuyeretsa nsalu zapangitsa kuti ikhale ndi mbiri yodziwika bwino ngati mankhwala oyeretsa.Kaya ndi madontho amakani a vinyo pa malaya omwe mumawakonda kapena nsalu zofiirira, sodium persulfate imatha kuthana ndi zovuta izi.

Kuphatikiza apo, sodium sulfate imawonetsa ma oxidizing amphamvu.Izi zimapangitsa kuti zikhale zabwino pothandizira kusintha kwamankhwala komwe kumafunikira kuchotsedwa kwa ma electron.M'mafakitale omwe amadalira kwambiri njira zamakutidwe ndi okosijeni, monga kupanga mankhwala ndi utoto, sodium persulfate imatsimikizira kukhala chinthu chamtengo wapatali.

Kuphatikiza apo, pawiri iyi imagwiranso ntchito ngati othandizira emulsion polymerization.Kwa omwe sadziwa mawuwa, emulsion polymerization amatanthauza njira yopangira ma polima mu sing'anga yamadzi.Sodium sulfate imagwira ntchito ngati chothandizira, imathandizira kupanga ma polima awa.Makampani omwe amagwiritsa ntchito emulsion polymerization, monga zomatira ndi zokutira, amadalira kwambiri sodium sulfate kuti agwire bwino ntchito pokwaniritsa zomwe akufuna.

Mkhalidwe wochuluka wa sodium sulfate ndi umene umasiyanitsa ndi mankhwala ena.Kuthekera kwake kugwira ntchito ngati bleaching agent komanso oxidant kumapangitsa kuti ikhale njira yowoneka bwino pamafakitale osiyanasiyana.Kuonjezera apo, emulsion polymerization kulimbikitsa katundu kumawonjezera kufalikira kwake kwa ntchito.

Kuphatikiza pa kugwiritsidwa ntchito kwake kosiyanasiyana, sodium sulfate ilinso ndi zinthu zina zingapo zosiyanitsa.Kusungunuka kwake m'madzi kumawonjezera mphamvu yake ngati bleach ndi okosijeni, ndikupangitsa kuti isungunuke ndikulumikizana ndi zinthu zina.Kumbali inayi, kusasungunuka kwake mu ethanol kumalepheretsa kusokoneza njira zomwe zimadalira Mowa monga zosungunulira.

Kuti mutsimikizire kugwiritsa ntchito bwino kwa sodium sulfate, ndikofunikira kulingalira zinthu zina.Kusamalira mosamala komanso kutsatira malangizo achitetezo ndikofunikira chifukwa chokhoza kukhala chowopsa.Kuphatikiza apo, mulingo woyenera ndi wofunikira mukaphatikiza sodium sulfate munjira iliyonse, kaya bleaching, oxidation, kapena emulsion polymerization.

Njira zodzitetezera:ntchito yotsekedwa, kulimbikitsa mpweya wabwino.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Ndibwino kuti ogwira ntchito azivala chovundikira chamutu chamtundu wamagetsi operekera mpweya wopumira fumbi, zovala zoteteza polyethylene, ndi magolovesi a rabala.Khalani kutali ndi moto ndi kutentha.Osasuta fodya kuntchito.Pewani kutulutsa fumbi.Pewani kukhudzana ndi zochepetsera, ufa wachitsulo wogwira ntchito, alkalis, mowa.Pogwira, kukweza ndi kutsitsa pang'ono kuyenera kuchitidwa pofuna kupewa kuwonongeka kwa zotengera ndi zotengera.Osagwedezeka, kukhudza ndi kukangana.Okonzeka ndi lolingana zosiyanasiyana ndi kuchuluka kwa moto zida ndi kutayikira mwadzidzidzi mankhwala zida.Zotengera zopanda kanthu zitha kukhala ndi zotsalira zoyipa.

Kusamala posungira:Sungani m'nyumba yosungiramo yozizirira, youma komanso mpweya wabwino.Khalani kutali ndi moto ndi kutentha.Kutentha kwa nkhokwe sikuyenera kupitirira 30 ℃, ndipo chinyezi sichiyenera kupitirira 80%.Phukusili ndi losindikizidwa.Iyenera kusungidwa mosiyana ndi zochepetsera, ufa wachitsulo wogwira ntchito, alkalis, alcohols, etc., ndipo sayenera kusakanikirana.Malo osungira ayenera kukhala ndi zida zoyenera kuti pakhale kutayikira.

Pomaliza, sodium sulfate imakhalabe yosunthika komanso yofunikira kwambiri.Kuchita bwino kwake monga bleach, oxidant, ndi emulsion polymerization wolimbikitsa kumayika pakufunika kwambiri.Ndi mankhwala ake a Na2S2O8, ufa woyera wa crystalline ukupitiriza kugwira ntchito yofunikira m'mafakitale osiyanasiyana.Mofanana ndi mankhwala aliwonse, ndikofunikira kuti mugwiritse ntchito sodium sulfate mosamala ndikukumbukira mlingo woyenera.Chifukwa chake, nthawi ina mukadzafuna bleach yodalirika kapena oxidant, lingalirani zofikira pa sodium sulfate, mphamvu yamagetsi yomwe silephera kupereka zotsatira zapadera.
