Sodium persulfate

Sodium persulfate, yomwe imadziwikanso kuti sodium persulfate, ndi chinthu chosapangidwa ndi zinthu zachilengedwe, formula ya mankhwala Na2S2O8, ndi ufa woyera wa kristalo, wosungunuka m'madzi, wosasungunuka mu ethanol, womwe umagwiritsidwa ntchito makamaka ngati bleach, oxidant, emulsion polymerization accelerator.

Katundu:Ufa woyera wa kristalo kapena kristalo. Palibe fungo. Wosakoma. Fomula ya molekyulu Na2S2O8, kulemera kwa molekyulu 238.13. Imawola pang'onopang'ono kutentha kwa chipinda, ndipo imatha kuwola mwachangu potenthetsera kapena mu ethanol, pambuyo pake mpweya umatulutsidwa ndipo sodium pyrosulfate imapangidwa. Chinyezi ndi platinamu wakuda, siliva, lead, chitsulo, mkuwa, magnesium, nickel, manganese ndi ma ayoni ena achitsulo kapena ma alloys awo amatha kukulitsa kuwola, kutentha kwambiri (pafupifupi 200℃) kuwola mwachangu, kutulutsa hydrogen peroxide. Kusungunuka m'madzi (70.4 pa 20℃). Ndi oxidizing kwambiri. Kukwiya kwambiri pakhungu, kukhudzana kwa nthawi yayitali ndi khungu, kungayambitse ziwengo, kuyenera kusamala ndi opaleshoniyo. Rat transoral LD50895mg/kg. Sungani bwino. Laboratory imapanga sodium persulfate potenthetsera yankho la ammonium persulfate ndi caustic soda kapena sodium carbonate kuti ichotse ammonia ndi carbon dioxide.

Wothandizira kwambiri oxidizing:Sodium persulfate ili ndi okosijeni wamphamvu, ingagwiritsidwe ntchito ngati chothandizira okosijeni, imatha kupangitsa kuti Cr3+, Mn2+, ndi zina zotero zilowe m'malo ofanana ndi okosijeni wambiri, pamene pali Ag+, ikhoza kulimbikitsa momwe okosijeni ali pamwambawa amachitira; Ikhoza kugwiritsidwa ntchito ngati chothandizira kuyera, chothandizira kuchiza pamwamba pa chitsulo ndi chothandizira cha mankhwala chifukwa cha mphamvu yake yopangitsa okosijeni. Zipangizo zopangira mankhwala; Zothandizira ndi zoyambitsa ma polymerization a batri ndi emulsion.

Kugwiritsa ntchito：Sodium persulfate imagwiritsidwa ntchito kwambiri ngati bleach, oxidant, komanso emulsion polymerization accelerator. Kutha kwake kuchotsa mabala ndi kuyeretsa nsalu kwapangitsa kuti ikhale yotchuka ngati bleach. Kaya ndi mabala a vinyo omwe amaoneka pa shati lanu lomwe mumakonda kapena nsalu zosinthika, sodium persulfate imatha kuthana ndi mavutowa mosavuta.

Kuphatikiza apo, sodium persulfate imasonyeza mphamvu zamphamvu zopangitsa kuti zinthu ziume. Izi zimapangitsa kuti ikhale yabwino kwambiri pothandiza pa zochita za mankhwala zomwe zimafuna kuchotsedwa kwa ma elekitironi. M'mafakitale omwe amadalira kwambiri njira zowola, monga kupanga mankhwala ndi utoto, sodium persulfate ndi chuma chamtengo wapatali.

Kuphatikiza apo, mankhwalawa amagwiranso ntchito ngati cholimbikitsira emulsion polymerization. Kwa iwo omwe sadziwa bwino mawuwa, emulsion polymerization imatanthauza njira yopangira ma polima mu aqueous medium. Sodium persulfate imagwira ntchito ngati chothandizira, kuthandiza kupanga ma polima awa. Makampani omwe amagwiritsa ntchito emulsion polymerization, monga zomatira ndi zokutira, amadalira kwambiri sodium persulfate kuti igwire bwino ntchito pokwaniritsa zotsatira zomwe akufuna.

Kuchuluka kwa sodium persulfate ndi komwe kumaisiyanitsa ndi zinthu zina. Kutha kwake kugwira ntchito ngati choyeretsera komanso ngati choteteza ku ma oxidant kumapangitsa kuti ikhale yokongola kwambiri m'mafakitale osiyanasiyana. Kuphatikiza apo, mphamvu zake zolimbikitsira emulsion polymerization zimakulitsa ntchito yake.

Kupatula ntchito zake zosiyanasiyana, sodium persulfate ili ndi zinthu zina zambiri zodziwika bwino. Kusungunuka kwa madzi ake kumawonjezera mphamvu yake ngati bleach ndi oxidant, zomwe zimapangitsa kuti isungunuke mosavuta ndikuyanjana ndi zinthu zina. Kumbali ina, kusasungunuka kwake mu ethanol kumalepheretsa kuti isasokoneze njira zomwe zimadalira ethanol ngati solvent.

Kuti muwonetsetse kuti sodium persulfate ikugwiritsidwa ntchito bwino, ndikofunikira kuganizira zinthu zina. Kusamalira mosamala ndikutsatira malangizo achitetezo ndikofunikira chifukwa cha kuopsa kwake. Kuphatikiza apo, mlingo woyenera ndi wofunikira kwambiri poika sodium persulfate mu njira iliyonse, kaya ndi bleaching, oxidation, kapena emulsion polymerization.

Zitetezo zogwirira ntchito:Kutseka ntchito, kulimbitsa mpweya wabwino. Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsatira mosamala njira zogwirira ntchito. Akulimbikitsidwa kuti ogwira ntchito azivala chopumira chamagetsi chofanana ndi chivundikiro cha mutu chomwe sichimawononga fumbi, zovala zoteteza polyethylene, ndi magolovesi a rabara. Sungani kutali ndi moto ndi kutentha. Osasuta fodya kuntchito. Pewani kutulutsa fumbi. Pewani kukhudzana ndi zinthu zochepetsera kutentha, ufa wachitsulo wogwira ntchito, alkalis, mowa. Mukagwira ntchito, kunyamula ndi kutsitsa zinthu pang'ono kuyenera kuchitika kuti mupewe kuwonongeka kwa ma CD ndi ziwiya. Musagwedezeke, kugwedezeka ndi kukangana. Okonzeka ndi mitundu yosiyanasiyana ya zida zoyatsira moto komanso zida zochizira mwadzidzidzi zomwe zimatuluka. Ziwiya zopanda kanthu zitha kukhala ndi zotsalira zovulaza.

Malangizo Osungira Zinthu:Sungani m'nyumba yosungiramo zinthu yozizira, youma komanso yopatsa mpweya wabwino. Sungani kutali ndi moto ndi kutentha. Kutentha kwa thanki sikuyenera kupitirira 30℃, ndipo chinyezi sichiyenera kupitirira 80%. Phukusili lili lotsekedwa. Liyenera kusungidwa padera ndi zinthu zochepetsera kutentha, ufa wachitsulo wogwira ntchito, alkalis, alcohols, ndi zina zotero, ndipo lisasakanizidwe. Malo osungiramo zinthu ayenera kukhala ndi zipangizo zoyenera kuti zisatuluke madzi.

Pomaliza, sodium persulfate ikadali chinthu chogwiritsidwa ntchito mosiyanasiyana komanso chofunikira kwambiri. Kugwira ntchito kwake ngati chothandizira bleach, oxidant, ndi emulsion polymerization kumapangitsa kuti chifunike kwambiri. Ndi njira yake ya mankhwala Na2S2O8, ufa woyera wa crystalline uwu ukupitilizabe kugwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana. Monga mankhwala ena aliwonse, ndikofunikira kugwiritsa ntchito sodium persulfate mosamala ndikuganizira mlingo woyenera. Chifukwa chake, nthawi ina mukadzafuna bleach kapena oxidant yodalirika, ganizirani kugwiritsa ntchito sodium persulfate, chinthu champhamvu chomwe sichilephera kupereka zotsatira zabwino kwambiri.
