Embodiment 1
[0024] Disperse 0.05 parts of papermaking white mud waste residue powder into 100 parts of deionized water, then disperse into 100 parts of commercial ASA at a stirring speed of 10,000 rpm, and continue stirring for 6 minutes to prepare a stable O / W type ASA emulsion , within 24 hours the emulsion was uniform, stable and non-separated.
[0025] Take 100 parts of poplar BCTMP pulp with a beating degree of about 42°SR and add it to 9900 parts of water. 2 (SO 4 ) 3 , mixed evenly to form a paper material, and passed through a rapid Kaiser method paper sheet former to a quantitative value of 60g / m 2 The hand-made sheet was dried in a drying cylinder at 105°C for 10 minutes, and the sizing degree of the hand-made sheet was measured to be 98s by liquid penetration method (GB / T5405-2002).
[0026] After the prepared emulsion was left to stand for 1 hour, the same operation was carried out according to the above steps, and the sizing degree of the hand-made sheet was measured to be...
