Monga mtsogoleri pa ntchito yosamalira madzi,sodium hexametaphosphateimagwira ntchito yofunika kwambiri pakukweza ubwino wa madzi. Choyamba, imatha kuchotsa bwino zinthu zopachikidwa ndi zonyansa za colloidal m'madzi, ndikulimbikitsa kupumira ndi kulekanitsa zonyansa popanga ma polima akuluakulu. Mbali imeneyi ndi yofunika kwambiri pochiza madzi otayira m'mafakitale ndi zimbudzi zapakhomo. Kachiwiri, sodium hexametaphosphate, yokhala ndi mphamvu yolimba yolumikizirana, imalumikizana bwino ndi ma calcium ndi ma magnesium ions m'madzi olimba, imaletsa bwino kupangika kwa sikelo, ndipo ndiyofunikira pakusamalira makina operekera madzi otentha, ma boiler, nsanja zoziziritsira ndi zida zina. Kuphatikiza apo, imathanso kusintha pH ya madzi, potulutsa ma phosphate ions ndi ma sodium ions, ndikuyanjana ndi ma hydrogen ions ndi ma hydroxide ions m'madzi kuti zitsimikizire kuti madzi ndi abwino komanso kukwaniritsa zosowa zosiyanasiyana. Monga wogulitsa sodium hexametaphosphate, Aojin Chemical idzagawana nanu lero momwe sodium hexametaphosphate imagwiritsidwira ntchito pochiza madzi:
1. Choletsa dzimbiri: Sodium hexametaphosphate imatha kusakanikirana ndi ayoni achitsulo (monga calcium ndi magnesium) m'madzi kuti ipewe kukulira kwa mapaipi ndi zida, motero imachepetsa dzimbiri ndi kukulira. Imagwiritsidwa ntchito kwambiri m'mafakitale oyendera madzi.
2. Chotulutsira madzi: Sodium hexametaphosphate imatha kufalitsa tinthu tomwe timapachikidwa m'madzi ndikuletsa kuti tisakhazikike, motero imawonjezera mphamvu yokonza zinyalala. Pokonza zinyalala, imatha kuletsa matope kuti asakhazikike komanso kusintha zotsatira zake.
3. Chothandizira kuyeretsa: Chimasakanikirana ndi ma ayoni a zitsulo zolemera kuti achepetse poizoni ndi ntchito zawo, ndipo chimagwiritsidwa ntchito pochiza madzi otayira okhala ndi zitsulo zolemera ndikuchepetsa kuipitsa kwa zitsulo zolemera.
4. Chofewetsa: Chimakumana ndi ma ayoni a calcium ndi magnesium m'madzi kuti chisapangike ngati mamba, choyenera kugwiritsidwa ntchito pa ma boiler ndi makina oziziritsira madzi kuti chisapangike ngati mamba.
5. Coagulant: Imalimbikitsa kugawanika kwa tinthu tomwe timapachikidwa, imathandizira mvula kapena kusefa, komanso imapangitsa kuti madzi olimba ndi olimba azigawanika. Imagwiritsidwa ntchito kwambiri pogawanika ndi kugawanika kwa madzi.
6. Woyang'anira pH: sinthani pH ya zinyalala ndikukonza bwino momwe mankhwala amagwiritsidwira ntchito. Ndi yoyenera njira zochizira zomwe zimafuna pH yeniyeni, monga momwe zimakhudzira kukana kwa madzi.
7. Chochotsa phosphorous: Chimasakanikirana ndi phosphates kuti chipange ma precipitates osasungunuka, chimachotsa phosphorous, ndipo chimagwiritsidwa ntchito kulamulira madzi a eutrophic
8. Zitsanzo zenizeni za momwe sodium hexametaphosphate imagwiritsidwira ntchito pochiza madzi ndi izi:
Dongosolo la madzi ozungulira mafakitale: Monga choletsa dzimbiri, limachepetsa dzimbiri ndi kukula
Kuchiza madzi otayidwa: Monga chotulutsira madzi otayidwa ndi cholumikizira madzi kuti chiwongolere kugwira ntchito bwino kwa mankhwala
Kuchiza madzi otayira pogwiritsa ntchito zitsulo zolemera: Monga chothandizira kuchepetsa kuipitsa kwa zitsulo zolemera
Boiler ndi makina oziziritsira madzi: Monga chofewetsera kuti chisapangike ngati mamba
Njira yolumikizira ndi kuyika kwa madzi: Monga cholumikizira kuti chiwongolere kusiyana kwa madzi olimba
Kuchitapo kanthu kwa neutralization: Monga wolamulira pH, konzani bwino momwe chithandizo chilili
Kuchiza madzi okhala ndi phosphorous: Monga chochotsera phosphorous, chepetsani kuchuluka kwa phosphorous
Monga mankhwala othandiza pochiza madzi,sodium hexametaphosphateIli ndi ntchito zambiri m'magawo osiyanasiyana. Imaletsa bwino kupanga zinthu zolemera ndi dzimbiri kudzera mu kupangika, kufalikira ndi kutsekereza, imateteza zida ndi mapaipi, komanso imakweza ubwino wa madzi ndi magwiridwe antchito a zida.
