 2,Performance & Features:

    1.Good defoaming, antifoaming performance and long duration.

    2.There is no resistance to the performance of other chemicals in the pulp, can remove the                       bubble in the slurry and white water.Effectively improve the dehydration, improve the paper wet             strength, reduce the paper on the pinhole, bubble, reduce the frequency of broken paper,                       improve production efficiency.

    3.Can effectively improve the retention of fine fibers and fillers, reduce the emissions of other                   paper chemicals and fiber organic load. This product adopts different molecular weight,                        different structure of polyether compound and into, soluble in water after the formation of                        emulsion.

   4. This product with different molecular weight and structure of polyether compound and into, soluble  in water after forming emulsion.

3,Scope of Application:

   1.Elimination of the bubble in papermaking wet end

   2.Applies to newsprint, cultural paper and packaging paper production process

   3.Suitable for the use of a variety of special paper production process

   4. The ability to disperse in water is good, especially for medium and acid process.

4,Application Methods:

   1.Strong foam, foam suppression performance, add a little to be effective, suggested usage 50-            500 g/MT, for the amount of added can be adjusted according to the actual situation.

   2. Can add in the molding net water receiving disc, under the net, white pit pool or machine outside        the white tank at any position. The optimum adding amount and adding point can be determined          according to the type of paper, paper additives type, production speed, gas content and so on.

   3.This product is soluble in cold water, warm water, easy mixing emulsifying.

   4. To avoid the interference of other chemicals in use process, if there is any surplus after using a            timely cover packing.
