Method for manufacturing reconstituted tobacco substrate by using dry method of paper making
A technology for reconstituting tobacco leaves and dry-process papermaking, which is applied in the preparation of tobacco, tobacco, application, etc., can solve the problems of substrate wet strength defect, limited speed, loss, etc., and achieves excellent tensile strength, excellent water resistance, and good processing. performance effect

Embodiment 1
[0030] After the wood pulp paddle is crushed and defibrated into short fibers, it is stored in the storage tank. The length of a single fiber is 2-8mm, and the metering air is sent to the forming head box, and removed by the antistatic rope 3 and / or antistatic net 5 At the same time as the electrostatic effect, the negative pressure generated by the vacuum box 4 makes the fibers form a fluffy, disorderly and staggered short and thin layer on the forming net through the air-laid method, and then sprays the glue on the surface of the substrate, and uses compression when spraying. The air fully atomizes the adhesive-containing material liquid, sprays it on the surface of the substrate, and at the same time sucks it under negative pressure on the back of the sprayed surface. 70% sugar, 15% carboxymethyl starch, 10% cyclodextrin, 5% carboxymethyl cellulose), the substrate sprayed with glue is transported to the oven for drying, and then the other side is processed by the same proces...
Embodiment 2
[0032] After the bamboo pulp paddle is defibrated into single fibers, it is stored in a storage tank with a fiber length of 2mm-5mm. 10% of tobacco powder (fragments) is mixed into the storage tank, and the metering air is sent to the forming head box. While the antistatic rope 3 and / or the antistatic net 5 remove the static effect, the negative pressure generated by the vacuum box 4 makes the fibers form a fluffy and disorderly staggered short fiber thin layer on the forming net through the air-laid method, and then Spray the glue, use compressed air to fully atomize the glue when spraying, spray it on the surface of the substrate, and suck it under negative pressure on the back of the sprayed surface at the same time, the spraying amount of the adhesive accounts for 4% of the weight of the dry sheet substrate (adhesive The mass ratio is: 50% chitosan, 20% pullulan starch, 10% dextrin, 5% carboxymethyl cellulose, 15% glucomannan), and the substrate sprayed with glue is transpo...
Embodiment 3
[0034] After the wood pulp board is defibrated into single fibers, it is stored in the storage tank, and 10% short tobacco stem fibers and 10% tobacco powder (fragments) are added to the storage tank at the same time. The fiber length is 2mm-5mm, and the metering The wind is sent to the forming head box, and the static electricity is removed by the antistatic rope 3 and / or the antistatic net 5. At the same time, the negative pressure generated by the vacuum box 4 makes the fibers form a fluffy disordered pattern on the forming net through the air-laid method. The stacked non-structural force substrate, and then spray the composite adhesive material liquid mixed with the material liquid to improve the quality of the paper-based absorbent. When spraying, use compressed air to fully atomize the composite material liquid and spray it on the surface of the substrate. At the same time, the surface of the sprayed surface Negative pressure suction on the back side, the spraying amount ...
