It mixes 9-11 minutes, it is spare.
The pH value of slurry obtained by step (3) is adjusted to 3.5-4 by step (4) with sulfuric acid solution;It again will with sodium hydroxide solution
PH value is adjusted to 9.5-10;It is that contained substance in slurry cannot be resisted to the ingredient of acid-base property to weed out that it, which is acted on,.
Step (5) slurry beating degree is controlled between 30-45 ° of SR;It is preferred that using the mashing mode of wire-dividing broom purification, effect
It is that fiber can be tightly combined, improves paper strength, reduces gap and improve contamination resistance.Main beating using wire-dividing broom purification
Slurry mode, effect is that fiber can be tightly combined, and improves paper strength, reduces gap and improves contamination resistance.
Dehydration in step (7) is:Online dehydration, vacuum dehydration and press dewatering.
As a kind of perferred technical scheme, the preparation method of outdoor high strengthening plate facing body paper of the present invention,
Include the following steps:
(1) waterpower size degradation is carried out to wood pulp, a concentration of 4-6% of pulping adds in pigment, it is spare to squeeze into pulping pond;
(2) by fillers dilute to 50 ± 5% concentration, high-speed stirred 9-11 is carried out with 1000 ± 50 revs/min of blenders
Minute, it is spare;
(3) mixture obtained by step (2) is squeezed into and is mixed 5-6 minutes in pulping pond obtained by step (1);
(4) pH value of slurry obtained by step (3) is adjusted to 3.5-4 with sulfuric acid solution, recycled 20-22 minutes;Hydrogen-oxygen is used again
Change sodium solution and pH value is adjusted to 9.5-10 cycles 20-22 minutes;
(5) by slurry obtained by step (4) after fiberizer mashing processing, slurry beating degree is controlled between 30-45 ° of SR;
(6) slurry obtained by step (5) is squeezed into and is filled with pond, between pH value is adjusted to 6-6.6 with aluminum sulfate, added in wet strong
Agent;
(7) slurry pumping obtained by step (6) to head box is dried through dehydration of surfing the Internet, vacuum dehydration, press dewatering, baking oven
Dry, press polish, curling, cutting are to get to outdoor high strengthening plate facing body paper.
