Semutungamiri mumunda wekuchenesa mvura,sodium hexametaphosphateinoita basa rinokosha mukuvandudza kunaka kwemvura. Chekutanga pane zvese, inogona kunyatso bvisa yakamiswa zvinhu uye colloidal tsvina mumvura, uye kukurudzira kunaya nekuparadzaniswa kwetsvina nekugadzira mapolima makuru. Iyi ficha inonyanya kukosha mukurapwa kwemvura yetsvina yeindasitiri uye tsvina yemumba. Chechipiri, sodium hexametaphosphate, ine simba rayo rekugadzirisa, rinonyatsobatana ne calcium uye magnesium ions mumvura yakaoma, inodzivisa kuumbwa kwechiyero, uye inokosha pakuchengetedza mvura inopisa, mabhoilers, shongwe dzekutonhora nemimwe michina. Uyezve, inogona zvakare kugadzirisa pH kukosha kwemvura, nekuburitsa phosphate ions uye sodium ions, uye kuita nehydrogen ion uye hydroxide ion mumvura kuve nechokwadi kugadzikana kwemvura uye kusangana nemhando dzakasiyana dzekushandisa. Semupi we sodium hexametaphosphate, Aojin Chemical ichagoverana newe nhasi mashandisirwo chaiwo e sodium hexametaphosphate mukurapwa kwemvura:
1. Corrosion inhibitor: Sodium hexametaphosphate inogona kusanganiswa nesimbi ions (yakadai se calcium ne magnesium) mumvura kudzivirira kukwira kwepombi nemidziyo, nokudaro kuderedza kukora nekuyera. Inoshandiswa zvakanyanya mumaindasitiri anotenderera emvura masisitimu.
2. Dispersant: Sodium hexametaphosphate inogona kuparadzira zvimedu zvakaturikwa uye kudzivirira kubva pakugadzirisa, nokudaro kuvandudza kushanda kwekuchenesa tsvina. Mukurapwa kwetsvina, inogona kudzivirira sludge kubva pakugadzirisa uye kugadzirisa mhedzisiro yekurapa.
3. Chelating agent: Inosanganiswa neheavy metal ions kuderedza huturu hwavo uye basa, uye inoshandiswa kurapa heavy metal-ine tsvina yemvura uye kuderedza heavy metal kusvibiswa.
4. Softener: Inopindirana ne calcium uye magnesium ions mumvura kudzivirira kuumbwa kwechiyero, yakakodzera kune mabhoilers uye inotonhodza mvura system kudzivirira kuwedzera.
5. Coagulant: Inosimudzira kubatanidzwa kwezvimedu zvakamiswa, inofambisa kunaya kana kusefa, uye inovandudza iyo yakasimba-mvura yekuparadzanisa mhedzisiro. Inoshandiswa zvakanyanya mu coagulation uye sedimentation maitiro
6. pH regulator: gadzirisa pH kukosha kwetsvina uye kugadzirisa mamiriro ekurapa. Inokodzera maitiro ekurapa anoda chaiyo pH kukosha, senge neutralization maitiro
7. Phosphorus remover: Inosanganiswa nephosphates kuita insoluble precipitates, inobvisa phosphorus, uye inoshandiswa kudzora eutrophic mvura mitumbi.
8. Mamiriro chaiwo ekushandiswa kwesodium hexametaphosphate mukurapwa kwemvura anosanganisira:
Indasitiri inotenderera yemvura system: Senge corrosion inhibitor, inoderedza corrosion uye kuyera.
Kugadziriswa kwemvura yetsvina: Se dispersant uye coagulant yekuvandudza kurapwa kwakanaka
Heavy metal wastewater treatment: Senge chelating agent kuderedza kusvibiswa kwesimbi inorema
Boiler uye inotonhora mvura system: Sechinyoro chekudzivirira kuumbwa kwechiyero
Coagulation uye sedimentation maitiro: Se coagulant yekuvandudza yakasimba-mvura yekuparadzanisa maitiro.
Neutralization reaction: Senge pH regulator, gadzirisa mamiriro ekurapa
Kurapa kwemitumbi yemvura eutrophic: Sekubvisa phosphorus, chengetedza phosphorus yemukati
Semugadziri wekuchenesa mvura anobudirira,sodium hexametaphosphateine maapplication akawanda mundima dzakawanda. Iyo inonyatso kudzivirira kuumbwa kwezviyero uye corrosion zvigadzirwa kuburikidza nekuoma, kupararira uye buffering, inodzivirira michina nemapombi, uye inovandudza kunaka kwemvura uye midziyo inoshanda zvakanaka.
