1, boiler kudyetsa madzi kuti asinthe mtengo wa zifukwa
Masiku ano, boulers ambiri ku China gwiritsani ntchito madzi osungunuka kapena sodium ion Mwa madzi a acidic amapezeka ndi mapaipi ndi mapaipi, malinga ndi momwe National Standard BG / T157662-2008, mtengo wamtengo wa madziwo ali pakati pa 8-9.5, kotero madzi a boiler amafunika kusintha mtengo wake.
2, mfundo yoyambirira yowonjezera sodium carbonate ya boiler kudyetsa madzi kuti asinthe mtengo
Sodium Carbonate imadziwika kuti ndi soda, phulusa la koloko, kutsuka alkali, kutsukidwa ndi mchere, osati mtundu wamba ufa woyera kapena mchere wabwino. Mfundo yofunika kwambiri yowonjezera sodium carbonate kwa obowola madzi kuti asinthe mtengo wa acidic kuti usungunuke madzi ndi madzi amchere ndi mapaipi amchere. Sodium Carbonate ndi electrolyte yofooka, kusungunuka m'madzi kuti apange yankho la bajebote ndi sodium bicarbonate, pali malire a electrolyc hydrolytide, motero SHAMISTE PERANI KUTI MUZISANGALALA.
Sodium Carbonate Gawo Loyambira:
Na2co3 sodium carbonate + h2o madzi = nahco3 sodium bicarbonate + Naoh sodium hydroxide
Sodium Carbonate yachiwiri hydrolysis dongosolo:
Nahco3 sodium bicarbonate + h2o madzi = h2co3 carbonic acidi + Naoh sodium hydroxide
Sodium carbonate yoyamba ya hydrolyzed ion equation:
(CO3) 2-carbonic acid + h2o madzi = hco3- bicarbonborbonate + oh
Sodium Carbonate yachiwiri ya hydrolyzd ion equation:
HCA3- Bicarbonate + H2O Madzi = h2co3 carbon + oh- hydroxide
3, mfundo yoyambirira yowonjezera sodium hydroxide ku madzi a boiler kuti musinthe mtengo wa pH
Sodium hydroxide imatchedwanso caustic soda, caustic soda, kosungunukira koloko, nthawi zambiri sodium Naoh, yotupa kwambiri.
Ionization equation ya sodium hydroxide: Naoh = na + 2-
Kuonjezera sodium hydroxide kumadzi a boiler omwe amatha kukhazikika pa filimuyo pazakudya ndi ng'anjo yowuma, ndikuteteza zida zachitsulo kuti zisawonongeke.
4. Ubwino ndi zovuta za kugwiritsa ntchito sodium carbonate kapena sodium hydroxide kusinthitsa PH Mtengo wa boiler kudyetsa Madzi a FAELER amafanizidwa
4.1 Kuthamanga kwa mtengo wokweza PH ndi sodium carbonate ndi sodium hydroxide kwa boiler kudyetsa madzi ndi nthawi yogwiritsira ntchito izi ndizosiyana
Kuthamanga kwa kuwonjezera sodium carbonate ya madzi obowola kuti awonjezere phindu la PH hydroxide. Chifukwa chakuti sodium carbonate yothetsera njira yothetsera mavuto, imakhala yovuta kwambiri komanso yokhazikika komanso yosavuta kusintha. Komabe, mtundu wa kusintha kwa mawu kuli kochepa. Mukasintha mtengo womwewo, kuchuluka kwa mafuta a sodium kudzakhala kokulirapo kuposa edium hydroxide. Kugwiritsa ntchito zotsatira kumasungidwa kwa nthawi yayitali, ndipo Ph ya madzi siophweka kugwa.
Sodium hydroxide ndi maziko olimba ndipo electrolyte yamphamvu, sodium hydroxide kapena mosavuta, komanso zosavuta kufalitsa zochulukirapo Kuchulukana, komabe, kuchuluka kwa sodium hydroxide kuwonjezera, ndiye kuti, kuthekera kwa madzi kusokoneza asidi wa gulu la hydroxide, poyambira.
4.2 Kuvulala koopsa kwa kuwonjezera kwambiri kwa sodium carbonate ndi sodium hydroxide kuti muwonjezere PH
Kuphatikiza kwambiri hadiom carbonate yamadzi obowola kuti asankhe mtengo wamtunduwu kuonjezera mchere wamchere wa madzi amoto ndi moyo; Pali ma ions ambiri a bicarbonate mu madzi m'madzi, ndipo ma ion a bicarbonate amasungidwa mosavuta kukhala kaboni dayokisayi ikatentha. CO2 amalowa mu kutentha kwa kutentha ndikulemekeza madzi ndi nthunzi. Sodium Carbonate osati kusinthira mtengo wa SHam ndi Steam Chemenstete madzi, komanso amachepetsa mtengo wa SHam ndikubweza, kuwongolera kutentha kwa kutentha ndi kufupika. Chifukwa chomwe zimapangitsa kuti chitsulo chachitsulo chobwezeretsani madzi obwezeretsanso mafuta ogwiritsa ntchito kapena ofiira.
Powonjezera kwambiri sodium hydroxide ku ng'anjo yamadzi kuti musinthe mtengo wa pH ukhale wokwera kwambiri, ndipo madzi ndi soda. Kuchuluka kwa sodium hydroxide sikophweka kuwongolera, ndipo kwaulere kwa Naoh mopitirira muyeso kwakukulu, ndipo ma alkali a alkali adzayambitsanso chivundikiro ku zida. Wolemba wawonapo chivundikiro cha pulasitiki chitsimikiziro chotsimikizika cha thanki yodzaza ndi masamba a wogwiritsa ntchito, omwe amathandizidwa ndikugwiritsa ntchito sodium hydroxide kuti ayang'anire mtengo wa PH. Sodium hydroxide sangathe kusintha mtengo wa steam ndi matenthedwe amabwezeretsa madzi, ndipo sangathe kuwongolera chilengedwe cha nthunzi ndi matenthedwe amakanema.
4.3 Chitetezo cha sodium carbonate ndi sodium hydroxide omwe amagwiritsidwa ntchito mu boiler kudyetsa madzi kuti akweze mtengo wa pH ndi yosiyana
Sodium Carbonate ndi yofatsa, imakhala ya chakudya chazakudya, zimayambitsa pang'ono, kutukuka pang'ono, kumayenera kukhudzidwa ndi dzanja, kuyenera kuvala magolovesi.
Sodium hydroxide ndi nkhani yoopsa, yotchinga, ndi fumbi lake kapena fumbi limapaka pakhungu, makamaka pa mbiya ya mucous, ndipo imatha kupanga zipewa zofewa. Kuwotcha masamba. Kufalikira m'maso, sikungowononga ziphuphu, komanso kuwononga minofu yakuya ya diso. Chifukwa chake, wothandizirayo ayenera kugwiritsa ntchito mafuta osokoneza bongo ndi hydrophobic pakhungu, ndipo ayenera kuvala zovala zapamwamba, masks, zovala zoteteza, magolovesi a mphira, kutetezedwa kwina ndi chitetezo chogwira ntchito kuti ateteze.
Pali zochitika zoyeserera zomwe zikuwonetsa: sodium hydroxide ndi sodium carbonate imagwiritsidwa ntchito mosiyanasiyana, kapena kusakaniza, chuma chake komanso zotsatira zake ndizabwino kuposa kugwiritsa ntchito ph wowongolera yekha. Mtengo wa pH ya bueler madzi owotcha amapezeka kuti ndi otsika, ma hydium hydroxide amatha kuwonjezeredwa moyenera kuti muwonjezere mtengo wa pH. Pambuyo pa sodium hydroxide imasungunuka kwathunthu, ma carbote a carbonate amathanso kuwonjezeredwa kuti alere carbonate m'madzi. Izi zitha kuchepetsa kuchepa kwa mtengo wa pH ya madzi odyetsa; Chifukwa kuchuluka kwa ma carbotete a carbonate akhoza kuyikanso zambiri, kuthekera kwa kateboni m'madzi ndi kochulukirapo, kotero kuti mtengo wa PH ndi madzi osakanikirana, kuti awiriwa agwiritse ntchito bwino ntchito.
