Monga mtsogoleri pazamankhwala a madzi,sodium hexametaphosphateamagwira ntchito yofunika kwambiri pakuwongolera madzi. Choyamba, imatha kuchotsa bwino zinthu zoyimitsidwa ndi zonyansa za colloidal m'madzi, ndikulimbikitsa mpweya ndi kulekanitsa zonyansa popanga ma polima akulu. Mbali imeneyi ndi yofunika kwambiri posamalira madzi otayira m’mafakitale ndi zimbudzi zapanyumba. Kachiwiri, sodium hexametaphosphate, ndi mphamvu zake zolimba zolimba, zimaphatikizana kwambiri ndi ayoni a calcium ndi magnesium m'madzi olimba, zimalepheretsa mapangidwe a sikelo, ndipo ndizofunikira pakukonza njira zoperekera madzi otentha, ma boilers, nsanja zozizirira ndi zida zina. Kuphatikiza apo, imathanso kusintha pH yamadzi, potulutsa ma phosphate ma phosphate ndi ayoni a sodium, komanso kuchitapo kanthu ndi ayoni a haidrojeni ndi ma hydroxide m'madzi kuti atsimikizire kukhazikika kwamadzi ndikukwaniritsa zosowa zosiyanasiyana zamagwiritsidwe ntchito. Monga ogulitsa sodium hexametaphosphate, Aojin Chemical akugawana nanu ntchito zenizeni za sodium hexametaphosphate pochiza madzi:
1. Corrosion inhibitor: Sodium hexametaphosphate ingaphatikize ndi ayoni zitsulo (monga calcium ndi magnesium) m'madzi kuteteza mapaipi ndi zida, potero kuchepetsa dzimbiri ndi makulitsidwe. Amagwiritsidwa ntchito kwambiri m'mafakitale ozungulira madzi.
2. Dispersant: Sodium hexametaphosphate imatha kumwaza tinthu tating'onoting'ono ndikulepheretsa kukhazikika, potero kumapangitsa kuti zimbudzi ziziyenda bwino. Pochiza zimbudzi, zimatha kuteteza matope kuti asakhazikike ndikuwongolera zotsatira zamankhwala.
3. Chelating agent: Amaphatikiza ndi ayoni azitsulo zolemera kuti achepetse kawopsedwe ndi ntchito zawo, ndipo amagwiritsidwa ntchito poyeretsa madzi otayira okhala ndi zitsulo zolemera komanso kuchepetsa kuwonongeka kwa zitsulo zolemera.
4. Softener: Imasanganikirana ndi ayoni a calcium ndi magnesium m'madzi kuti aletse mapangidwe a sikelo, oyenera ma boilers ndi makina oziziritsira madzi kuti asachuluke.
5. Coagulant: Amalimbikitsa coagulation ya inaimitsidwa particles, facilitates mpweya kapena kusefera, ndi bwino olimba-zamadzimadzi kulekana kwenikweni. Amagwiritsidwa ntchito kwambiri mu coagulation ndi sedimentation process
6. pH regulator: sinthani mtengo wa pH wa zimbudzi ndikuwongolera mikhalidwe yamankhwala. Ndiwoyenera njira zochizira zomwe zimafunikira pH yamtengo wapatali, monga machitidwe a neutralization
7. Phosphorus remover: Amaphatikiza ndi phosphates kupanga precipitates osasungunuka, amachotsa phosphorous, ndipo amagwiritsidwa ntchito kuwongolera matupi amadzi a eutrophic.
8. Zochitika zenizeni zogwiritsira ntchito sodium hexametaphosphate pochiza madzi ndi monga:
Dongosolo lamadzi ozungulira mafakitale: Monga inhibitor ya corrosion, imachepetsa dzimbiri komanso makulitsidwe.
Kuchiza kwamadzi otayira: Monga dispersant ndi coagulant kuti chithandizo chamankhwala chikhale bwino
Chithandizo chamadzi otayira zitsulo zolemera: Monga chothandizira kuchepetsa kuipitsidwa ndi zitsulo zolemera
Boiler ndi madzi ozizira: Monga chofewetsa kuteteza mapangidwe a sikelo
Coagulation ndi sedimentation process: monga coagulant kuti apititse patsogolo kulekanitsa kwamadzi olimba.
Neutralization reaction: Monga pH regulator, konzani zikhalidwe za chithandizo
Chithandizo cha matupi amadzi a eutrophic: Monga chochotsa phosphorous, wongolerani phosphorous
Monga wothandizira bwino wothira madzi,sodium hexametaphosphateali ndi ntchito zambiri m'magawo ambiri. Imalepheretsa kupanga masikelo ndi dzimbiri popanga zovuta, kubalalitsidwa ndi kubisala, kuteteza zida ndi mapaipi, ndikuwongolera madzi abwino komanso zida zogwirira ntchito bwino.
