Scale inhibitor for oil fieldAdd time:2016-12-28
The role of water treatment agent scale inhibitor： delay， reduce or inhibit scaling.
Scale inhibitor is the most commonly used to prevent scale crystal growth， the inhibitor must be in small crystals just formed from the water when the water.
Inorganic phosphate： three sodium phosphate (Na3PO4)， sodium pyrophosphate (Na4P2O7)， sodium hexametaphosphate ()， sodium tripolyphosphate (NaPO3)， sodium tripolyphosphate (Na5P3O10) ().
Features?
1， low price of drugs， anti calcium carbonate expansion more effective.
2， easy hydrolysis， the production of orthophosphate， calcium ions， insoluble calcium phosphate；
3， with the increase of water temperature， hydrolysis rate.
4， the maximum operating temperature of 80 degrees C.
Organic phosphoric acid and its salts： amino trimethylene phosphonic acid (ATMP)， ethylenediamine tetramethylene phosphonic acid (EDTMP)， Qiang Jiyi fork two sodium phosphate (HEDP).
Features锛?
1， is not easy to hydrolysis
2， better anti scaling effect of low dose
3， good compatibility with other sewage treatment chemicals
4， the use of temperature can reach 100 degrees Celsius
Polymer： polyacrylic acid (PAA)， polyacrylamide (PMA)， maleic anhydride (HPMA)， etc.. HPMA prevent CaSO4， BaSO4 scale effect is good.
Mixed type compound： several different functions of single agent in a certain proportion of mixed， as long as no reaction between each other， no offset， and play their respective characteristics， can be used as a compound.
