Method for producing low-dosing newsprint paper by using unitary retention and filter aid

Номер: CN0101215800A
Принадлежит:

The invention discloses a process for producing low definite quantity newsprint paper with monobasic retention and filter aid, the process comprises adopting 5%-15% chemical supergroundwood and 85%-95% void waste newsprint paper pulp to be raw material, only adding polymer K380 to be retention and drainage agent, and producing low definite quantity newsprint paper whose quality reaches and is better than GB/T 1910-2006 newsprint paper standard which is 45g/m2 on a high-speed paper machine. Quantity and dosage of chemical can be reduced through adding monobasic retention and filter aid to produce low definite quantity newsprint paper. The invention reduces environmental contamination when the production cost is lowered, and the production flow and the operation are simplified.

Method for producing low basis weight newsprint by 100 percent deinking waste pulp added with retention and drainage agent

Номер: CN0101225615B
Принадлежит:

The invention discloses a preparation method for low basis weight newsprint by using 100% de-inking waste paper pulp added with retention and filter aid, which comprises a plurality of steps: add 100% de-inking waste paper pulp into a proportioning tank of a high-speed paper machine; then add calcium carbonate and fixing cation modified polyamines; add starch at the entrance of a machine chest; use tray water to flush the pulp at the outlet of the machine chest; control the wite pulp concentration at 1.0%; after desanding and deaerating, add the retention aid cation water soluble macromolecule polyacrylamide derivative at the outlet of a sizing pump and the inlet of a vertical screen; add filter aid polyethylenimine at the outlet of the vertical screen; the pulp is sent into a head box ofthe high-speed paper machine; thus, the low basis weight newsprint can be produced. The preparation method for low basis weight newsprint by using 100% de-inking waste paper pulp added with retentionand ...

Method for measuring micro stickies in paper pulp slurry and uses thereof

Номер: CN0101551364A
Принадлежит:

The present invention discloses a method for measuring micro stickies in paper pulp slurry and uses thereof. When stickies particle size is far smaller than 1, namely as micro stickies, amount of the micro stickies is directly proportional to tracer adsorbance, the relationship between tracer chromatographic peak area (A) and micro stickies concentration (S) is: A= a-b S, a stands for intercept while b stands for slope. Through preparation of standard curve is able to measure micro stickies content in paper pulp slurry accurately and rapidly. The method of measuring micro stickies in paper pulp slurry of the invention is applied to waste paper manufacture field, which can monitor stickies harm effectively, consequently guaranteeing normal running of waste paper manufacture production.
