Abstract
Through twice of independent pulp injecting of the face pulp and bottom pulp and twice vacuum pumping and dewateirng, paper product with two closely combined layers of face layer in 10-50 % and bottom layer in 50-90 % is produced. In the product, only waterproofing agent to increase deflection degree and decrease density is added to the bottom layer; and oil preventing agent and waterproofing agent are added to the face layer to reduce consumption. The face pulp is groud fine pulp capable of increasing assistant retention and raising the deflection degree of product and decreasing assistant consumption. The two layers of different paper fiber arranging direction makes the product processes high deflection degree.
Description
The present invention relates to a kind of employing grouting process and produce paper products, especially a kind of secondary grouting technology and products thereof.
At present in the related known technology, the basic once grouting technology that adopts, in order to improve water resistance, anti-moisture regain performance, anti-adhesive properties, stiffness and surface smoothness etc. need add additive in slurry, have some quite expensive in these additives, as oil-proofing agent etc., the oil-proofing agent that only is present on the finished surface could effectively play a role, and the composition that is present in other parts does not play a role, form waste of material, have the phenomenon of the mutual reduction effect of bringing into normal play each other on the other hand between the portions additive, thereby in the improvement project to once grouting technology, cost often occurring increases, and the phenomenon that performance is not obviously improved.
The objective of the invention is to propose a kind of performances such as surface smoothness that can obviously improve finished product, the production technology that also reduces cost simultaneously.
The objective of the invention is to realize: in the formed product process by following technical measures, with separate prime cement and starch adhesive slip casting respectively, vacuumize dehydration twice, formation has the finished product made of paper of bottom and two aspects of combining closely of surface layer, bottom accounts for 50---and 90%, surface layer accounts for 10---and 50%.
The present invention only need add waterproofing agent in bottom, can add 30 simultaneously---40% the lower filler of price, increase the product stiffness, and reduce product weight, in surface layer, add oil-proofing agent, waterproofing agent, consumption reduction is more than 40%.Starch adhesive adopts the fine grinding slurry, helps increasing auxiliary agent and keeps, and significantly improves the stiffness of product, reduces promoter addition, adopts secondary grouting technology, forms the different crisscross aspects of arranging of two paper fibers, further improves the product stiffness.According to the different requirements to different product, auxiliary agent kind and the ratio that only need adjust prime cement and starch adhesive respectively get final product.
The present invention is further described by the following examples:
Embodiment 1: in the formed product process, with the slip casting respectively of separate prime cement and starch adhesive, vacuumize dehydration twice, form the finished product made of paper with bottom and two aspects of combining closely of surface layer, bottom accounts for 50---and 90%, surface layer accounts for 10---and 50%.
Supernatant water is annotated prime cement behind the matched moulds, vacuumizes liquid level and reduces by 2/3, is evacuated to clear water behind the notes starch adhesive and does, the die sinking typing.Require starch adhesive thickness even, do not dash wet mould, do not drip after the die sinking and starch not hanging.
Embodiment 2: only need add waterproofing agent in the bottom, can add 30 simultaneously---40% the lower filler of price, increase the product stiffness, and reduce product weight, in surface layer, add oil-proofing agent, waterproofing agent, consumption reduction is more than 40%.
Embodiment 3: starch adhesive adopts the fine grinding slurry, helps increasing auxiliary agent and keeps, and significantly improves the stiffness of product, reduces promoter addition.
Embodiment 4: use secondary grouting technology, form the different crisscross aspects of arranging of two paper fibers, further improve the product stiffness.
Because relate to two cover pulp feeding systems among the present invention, production and equipment control are more complicated, power consumption has certain increase, and requiring in the production process must be harmonious, and operation or meeting out of trim cause waste product in enormous quantities.
Claims (4)
