what is mechanism that Cook stove include trisodium phosphate?

Cook stove is making use of Trisodium Phosphate and sodium mixture, 3 from the 2Mon 0.5 ~ ~ ~ 24 48h below pressure, except the heating oil, go and make the material surface area fascination scale.

For newly set up boiler, mostly from production and also the essential oil pipe, which can be centered around the bottom of grease saponification and sterilization role. Their acid, response towards representative for:

　C17H33COOH十NaOH→C17H33COONa十H2O

　　C17H33COOH十Na3PO4→C17H33COONa十Na2HPO4

Fatty acid (or other), insoluble in water, but in with sodium hydroxide and Trisodium Phosphate merchandise purpose soon after main hydrolysis, soluble of sodium produce was removed.

For the lime scale carbonate, lime scale sulfate and lime scale silicate, lime scale and magnesium scale of low-pressure boiler, little capability by cooking stove rescaling, will make the removing amount reaches above 60%. from the cook stove trisodium phosphate could be transformed in to the carbonate, sulfate, lime scale silicate and magnesium hydroxide, make to loose type of phosphate fall, Magnesium hydroxide could be transformed in to the silicate and silica, brings about it to grow to be loose or soluble, the response merchandise of for:

　　3CaCO3十2Na3PO4→Ca3(PO4)2十2Na2CO3

　　3CaSO4十2Na3PO4→Ca3(PO4)2十3Na2SO4

　　3Mg(OH)2十2Na3PO4→Mg3(PO4)2十6NaOH

　　CaSiO3十2NaOH→Ca(OH)2十Na2SiO3

　　Mg3Si2O7十4NaOH十H2O→3Mg(OH)2十2Na2SiO3

　　SiO2+2NaOH→Na2SiO3十H2O、

Cook stove rescaling mostly centered around the undissolved compound conversion principle, make the scale and cooking stove response gets loose potion, only a amount of scale was dissolved out. Therefore, from the cook stove should be completely flush soon after cleaning, or great loss of July scale slag furnace pipe and may well be blocked.
