Sodium percarbonate nws tus kheej yog cov tshuaj uas siv los yog ntxiv rau cov chaw tsim tshuaj ntxuav tes. Sodium percarbonate feem ntau pom muaj nyob rau hauv hmoov. Kab lus no yuav tham hauv qee qhov kev nthuav dav txog cov ntsiab lus tseem ceeb xws li txoj kev tau txais thiab siv, cov khoom ntawm cov khoom, thiab lwm yam. Thiab tam sim no hais txog tag nrho cov no hauv kev txiav txim.
Txoj kev tau txais sodium percarbonate
Ua ntej tshaj, sodium percarbonate yog cov khoom lag luam zoo ib puag ncig. Nyob rau hauv tus txheej txheem ntawm nws decomposition, ntau yam tshuaj lom los yog lwm yam tshuaj phem rau ib puag ncig tsis tshwm sim. Cov khoom ntawm cov decomposition muaj xws li: dej, dej qab zib thiab oxygen. Qhov tseeb no yog lwm qhov kev piav qhia rau kev siv dav dav ntawm cov tshuaj bleach no.
Hauv kev lag luam, muaj peb txoj hauv kev kom tau txais cov tshuaj no. Txhua tus ntawm lawv yog qhov sib txawv ntawm ib leeg. Hauv qab no, tag nrho peb txoj hauv kev yuav piav qhia ntau npaum li sai tau.
Tshuaj ib - crystallization
Thawj txoj kev, uas yog siv dav hauv kev lag luam, yog crystallization. Yuav pib nrog, ib qho dej qab zib tov, uas yog tov nrog peroxidehydrogen. Ntawm qhov kub ntawm li 20 degrees Celsius, kev sib cuam tshuam ntawm ob yam khoom no tshwm sim. Tsis tas li ntawd, crystallization yog nqa tawm nrog kev pab los ntawm stabilizers. Sodium percarbonate yog heev soluble, vim hais tias nws yog tsim nyog los ntsev nws tawm ntawm lub resulting sib tov. Ua li no, ntsev thiab ntau yam additives yog ntxiv rau nws. Siv lub centrifuge, crystalline percarbonate yog sib cais los ntawm kev sib tov thiab ces qhuav. Nws yog tsim nyog sau cia tias sodium percarbonate tau txais nyob rau hauv txoj kev no yog suav tias yog ib yam khoom uas tsis zoo heev vim muaj ntsev.
Thib ob txoj kev - txau
Thaum percarbonate yog mined los ntawm kev txau, kev siv lub centrifuge tsis tsim nyog. Xwb, cov tshuaj yog qhuav, uas muaj hydrogen peroxide thiab dej qab zib. Cov txheej txheem yuav siv qhov chaw nyob rau hauv lub tshuab ziab khaub ncaws. Cov khoom ntawm cov qauv no ntawm ntau lawm kuj muaj lawv cov minus - tsawg ntom. Tsis tas li ntawd, cov dej loj loj yuav tsum tau muab tshem tawm, ua rau cov nqi hluav taws xob siab.
Third method - qhuav
txheej txheem no yog thawj los ntawm cov tshuaj tiv thaiv qhuav. Qhov tsis zoo ntawm txoj kev tau txais cov lus dag nyob rau hauv cov tshuaj tiv thaiv mus ntev. Nws tseem yuav tsum tau ntxiv cov stabilizers tshwj xeeb, vim tsis muaj cov txheej txheem purification rau sodium percarbonate.
Cov txheej txheem no feem ntau siv rau dab tsi? Cov neeg tsim khoom siv sodium percarbonate hauv cov ntxhua khaub ncaws. Cov tshuaj ntxuav tes yuav tsum muaj cov ntsiab lus siab ntawm cov pa oxygen hauv nws. Ua tsaug rau peb txoj kev no, nws yog qhov ua tau kom tau txais percarbonate nrog qib siab O2. Tias yog vim li cas kev siv cov txheej txheem no thiaj li nrov hauv kev tsim khoom.
Sodium percarbonate: siv hauv cov tshuaj ntxuav tes thiab lwm qhov chaw ntawm lub neej
Bleach yog xav tau hauv cov hmoov lossis lwm yam tshuaj ntxuav tes. Sodium percarbonate yog qhov tseem ceeb. Nws zoo tshem tawm txawm tias hnyav tshaj stains thiab whitens ntxhua khaub ncaws. Tsis tas li ntawd, sodium percarbonate kuj yog siv los ua tshuaj tua kab mob. Nws muaj txiaj ntsig zoo rau cov xim ntawm cov ntaub hauv kev nkag siab tias cov xim ntawm cov khaub ncaws, txawm tias tom qab ntxuav ntau, yuav tsis poob.
Tsis tas li, sodium percarbonate yog siv rau lwm yam hauv tsev. Piv txwv li, hauv kev lag luam khoom noj khoom haus, cov tshuaj no yog siv los tua cov kab mob ua haujlwm. Hauv chemistry, nws plays lub luag haujlwm tseem ceeb sib npaug. Ntau cov tshuaj tiv thaiv oxidation tshwm sim siv tsuas yog sodium percarbonate.
Siv cov khoom ntshiab
Oxygen bleach sodium percarbonate hauv tsev tsis yog siv hauv cov hmoov xwb, tab sis kuj yog daim ntawv ntshiab. Nws tuaj yeem yuav los ntawm ntau lub khw muag khoom txhim kho tsev.
Nws tsim nyog nco txog tib neeg thiab kev nyab xeeb thaum siv. Percarbonate yog ib qho tshuaj lom neeg heev. Yog li ntawd nws yog txwv tsis pub ua hauj lwm nrog nws txhais tes liab qab. Nws yog qhov yuav tsum tau siv cov hnab looj tes roj hmab. Tsis tas li ntawd, cov tshuaj no yuav tsum tsis pub nkag mus rau hauv lub qhov muag lossis hauv lub cev.
Tam sim no peb yuav tsum tham txog yuav siv cov tshuaj no li cas hauv tsev neegxav tau, yog tias nws yuav hauv nws daim ntawv ntshiab.
- Siv cov khoom thaum ntxuav hauv lub tshuab ntxhua khaub ncaws. Yog tias tsim nyog tshuaj dawb, ob tablespoons ntawm percarbonate yuav tsum tau ntxiv rau lub tshuab ntxhua khaub ncaws, tab sis yog tias ntxuav zoo tib yam, ces ib qho txaus.
-
Yuav ntxuav tais diav hauv lub tshuab ntxuav tais diav, koj tsuas yog xav tau ib tablespoon ntawm cov khoom no.
- Yog tias ntxuav tau ua nrog ntub dej, ntawm no koj yuav tsum siv qhov feem ntawm ib tablespoon ntawm cov khoom ib liter dej. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tom qab soaking, nws yog ib qho tsim nyog yuav tsum tau ntxuav cov khaub ncaws hauv lub tshuab ntxhua khaub ncaws, tab sis tsis siv sodium percarbonate.
Nws yog ib qho tseem ceeb kom paub ib qho tseem ceeb heev. Sodium percarbonate pib ua thaum dej kub tshaj 50 degrees Celsius. Qhov zoo tshaj plaws tshwm sim yog tias cov dej kub yog 90 degrees Celsius. Qhov zoo ntawm cov tshuaj bleach no yog rinsing tag nrho. Koj tuaj yeem yaug cov khaub ncaws los ntawm percarbonate manually. Nws yuav tsis ntev.
Txoj cai khaws cia percarbonate hauv tsev
Qhov zoo tshaj plaws cia kub rau cov khoom no yog mus txog 30 degrees Celsius. Lub thawv ntawm percarbonate yuav tsum muab khaws cia rau hauv qhov chaw zoo tiv thaiv los ntawm tshav ntuj. Yog hais tias cov khoom nyob rau hauv ib lub warehouse, ces yuav tsum muaj cua nyob rau hauv lub chav tsev no. Lwm qhov tseem ceeb yog qhov tsis muaj cov khoom siv hluav taws xob nyob ze. Tsis tas li ntawd, tsis txhob khaws sodium percarbonate ze ntawm ntau cov kua qaub los yog kua ntim.
User tshuaj xyuas
Bleach yog siv los ntawm ntau tus neeg. Ntawm ntau lub rooj sab laj koj tuaj yeem nrhiav thiab nyeem cov tshuaj xyuas txog sodium percarbonate. Feem ntau lawv yog qhov zoo. Coob leej zoo siab tias cov tshuaj ntxuav tes no pab kom lawv tshem tau cov kab mob tawv ncauj.
Ib qho ntxiv uas cov neeg yuav khoom tau hais txog yog tias percarbonate tsis lwj cov xim ntawm cov khaub ncaws. Lawv tuaj yeem ntxuav tsis tau tsuas yog cov khoom dawb xwb, tab sis kuj yog cov xim, uas ua rau cov khoom no yog universal. Tsis tas li ntawd, percarbonate tsis lwj cov ntaub thiab tsis rhuav tshem nws txawm tias tom qab ntxuav ntau heev. Ntau tus neeg siv pom zoo kom cov tshuaj dawb no rau lwm tus neeg thiab.
