1.STUDY ON THE SALT RESISTANCE OF POLYELECTROLYTE USED AS TREATING AGENT OF DRILLING MUD(Ⅱ)—THE EFFECT OF SALT ON THE ADSORPTION PROPERTY OF THE POLYELECTROLYTE ON CLAY
2.The results showed the thermal stability of POM could be improved remarkably by applying triethanolamine as amine treatingagent through melting processing, and the optimum content of triethanolamine was 0.2%.
3.A standing and layering process for the regenerated acid purification is described. The treatingagent ANPA is added in regenerated acid and stood after agitation to purify it through layering.
4.The results showed that the dehydration of -SOC_3~- by salts was much less than that of -COO~-, and this was one of the reasons why SPU (Ⅱ) was a good salt-resistant treatingagent for drilling muds.
5.The experiment showed that the modified resin could improve its water proof property and cohesiveness, which was applied to the water proof treatingagent for paper and adhesive of water proof abrasive paper in coating abrasives.
