Joaloka moetapele lefapheng la pheko ea metsi,sodium hexametaphosphatee bapala karolo ea bohlokoahali ho ntlafatseng boleng ba metsi. Pele ho tsohle, e ka tlosa lintho tse emisitsoeng le litšila tsa colloidal ka metsing, 'me ea khothalletsa pula le ho arohana ha litšila ka ho etsa li-polymers tse kholo. Tšobotsi ena e bohlokoa haholo ho phekola metsi a litšila a indasteri le likhoerekhoere tsa malapeng. Taba ea bobeli, sodium hexametaphosphate, e nang le matla a matla a ho kopanya, e kopana haufi-ufi le calcium le magnesium ion metsing a thata, e thibela ka katleho sebopeho sa tekanyo, 'me e bohlokoa bakeng sa ho boloka tsamaiso ea metsi a chesang, li-boilers, litora tse pholileng le lisebelisoa tse ling. Ho feta moo, e ka boela ea fetola boleng ba pH ba metsi, ka ho lokolla li-ion tsa phosphate le sodium ion, le ho sebetsana le li-ion tsa hydrogen le hydroxide ions metsing ho netefatsa boleng bo tsitsitseng ba metsi le ho finyella litlhoko tse fapaneng tsa kopo. Joaloka morekisi oa sodium hexametaphosphate, Aojin Chemical e tla arolelana le uena kajeno ts'ebeliso e khethehileng ea sodium hexametaphosphate kalafo ea metsi:
1. Corrosion inhibitor: Sodium hexametaphosphate e ka kopana le li-ion tsa tšepe (tse kang k’halsiamo le magnesium) metsing ho thibela ho eketseha ha liphaephe le lisebelisoa, kahoo ho fokotsa ho bola le ho phahama. E sebelisoa haholo lits'ebetsong tsa metsi tse potolohang liindasteri.
2. Dispersant: Sodium hexametaphosphate e ka hasanya likaroloana tse emisitsoeng 'me ea li thibela ho lula, kahoo e ntlafatsa katleho ea tsamaiso ea likhoerekhoere. Phekolong ea likhoerekhoere, e ka thibela seretse ho lula le ho ntlafatsa litlamorao tsa kalafo.
3. Chelating agent: E kopanya le li-ion tsa heavy metal ho fokotsa chefo le tšebetso ea tsona, 'me e sebelisetsoa ho hloekisa metsi a litšila a nang le tšepe e boima le ho fokotsa tšilafalo ea tšepe e boima.
4. Softener: E sebetsana le li-ion tsa calcium le magnesium metsing ho thibela sebopeho sa sekala, se loketseng li-boilers le mekhoa ea metsi a pholileng ho thibela ho eketseha.
5. Coagulant: E khothalletsa ho kopana ha likaroloana tse emisitsoeng, ho nolofatsa pula kapa ho hloekisa, 'me ho ntlafatsa phello ea ho arohana ha metsi a tiileng. E sebelisoa haholo ts'ebetsong ea coagulation le sedimentation
6. pH regulator: lokisa boleng ba pH ba likhoerekhoere le ho ntlafatsa maemo a kalafo. E loketse lits'ebetso tsa kalafo tse hlokang boleng bo itseng ba pH, joalo ka karabelo ea neutralization
7. Phosphorus remover: E kopanngoa le phosphates ho etsa precipitates e sa qhibilihang, e tlosa phosphorus, 'me e sebelisetsoa ho laola libaka tsa metsi a eutrophic.
8. Maemo a ikhethileng a ts'ebeliso ea sodium hexametaphosphate kalafong ea metsi a kenyelletsa:
Sistimi e potolohang ea metsi ea indasteri: joalo ka corrosion inhibitor, e fokotsa ho bola le ho hola.
Phekolo ea metsi a litšila: Joalo ka sehlaseli le ho kopanya ho ntlafatsa ts'ebetso ea kalafo
Phekolo ea metsi a litšila a boima: Joalo ka sesebelisoa sa chelating ho fokotsa tšilafalo ea tšepe e boima
Boiler le sistimi ea metsi a pholileng: Joalo ka se bonolo ho thibela sebopeho sa sekala
Ts'ebetso ea coagulation le sedimentation: joalo ka coagulant ho ntlafatsa phello ea karohano ea metsi a tiileng.
Karabelo ea Neutralization: Joaloka molaoli oa pH, ntlafatsa maemo a kalafo
Kalafo ea 'mele oa metsi a eutrophic: Joaloka se tlosang phosphorus, laola lintho tsa phosphorus
Joaloka moemeli ea sebetsang hantle oa ho hloekisa metsi,sodium hexametaphosphatee na le lisebelisoa tse ngata libakeng tse ngata. E thibela ka katleho sebopeho sa lihlahisoa tsa sekala le kutu ka ho rarahana, ho hasana le ho thibela, ho sireletsa lisebelisoa le liphaephe, le ho ntlafatsa boleng ba metsi le lisebelisoa tse sebetsang hantle.
