Embodiment 1

[0035] Embodiment 1 (product specification 42g / ㎡):

[0036] A production process of wrinkled wiping paper, specifically comprising the steps of:

[0037] a. After the pure wood pulp is disintegrated by a hydropulper, it is subjected to disc grinding and beating to obtain a slurry with a concentration of 3.5 to 4.0 wt % and a degree of percussion of 18 to 20 ° SR;

[0038] B, the ultra-short viscose fibers are mixed with the slurry after being evacuated by a deflagging machine to obtain a mixed slurry, the mixed slurry contains 80wt% wood pulp and 20wt% ultra-short viscose fibers, and the slurry concentration is 2.5wt%;

[0039] c. Add paper softener, auxiliary agent and wet strength agent to the slurry, mix well, wet form through the inclined wire papermaking wire part former, press and dehydrate in the suction box, and enter the vat for pre-drying through the supporting roller. A large cylinder with a diameter of 3.5 meters is used for the pre-drying of the large cylinder. T...

Embodiment 2

[0053] Embodiment 2 (product specification 35g / ㎡):

[0054] A production process of wrinkled wiping paper, specifically comprising the steps of:

[0055] a. After the pure wood pulp is disintegrated by a hydropulper, it is subjected to disc grinding and beating to obtain a slurry with a concentration of 3.5 to 4.0 wt % and a degree of percussion of 18 to 20 ° SR;

[0056] B, ultra-short viscose fibers are mixed with the slurry after being evacuated by a deflagging machine to obtain a mixed slurry, the mixed slurry contains 85wt% wood pulp and 15wt% ultra-short viscose fibers, and the slurry concentration is 2.5wt%;

[0057] c. Add paper softener, auxiliary agent and wet strength agent to the slurry, mix well, wet form through the inclined wire papermaking wire part former, press and dehydrate in the suction box, and enter the vat for pre-drying through the supporting roller. Large cylinder pre-drying adopts a large cylinder with a diameter ≥ 3 meters. Two suction hoods are in...

Abstract

The invention relates to a paper product processing method, in particular to a production technology of crinkled wiping paper, and belongs to the technical field of paper making and paper product processing and production. The production technology of the crinkled wiping paper includes the following steps that firstly, pure wood pulp is subjected to repulping through a hydraulic repulping machine, then millstone mill pulping is carried out, and pulp with the concentration of 3.5-4.0wt% and the SR beating degree of 18-20 is obtained; secondly, ultrashort viscose fibers are fluffed through a fluffer and then mixed with the pulp, and mixed pulp is obtained; thirdly, a softening agent, auxiliaries and a wet strength agent for paper are added into the mixed pulp and mixed evenly, the mixture is subjected to wet-process forming through an inclined-wire papermaking net part former, and the product is squeezed and dehydrated through a water absorption box and enters a vat to be pre-dried; fourthly, the body paper entering the vat is subjected to coating on the surface of the vat, the sizing amount is controlled to be within 2-5 g / m<2> according to paper requirements, crinkling occurs on the surface of the drying vat, and after vat-combined drying and finishing, cooling and rolling, rewinding and slitting, and packaging and warehousing, production of the product is completed.

Description

technical field [0001] The invention relates to a paper product processing method, in particular to a production process of wrinkled wiping paper, and belongs to the technical field of papermaking and paper product processing and production. Background technique [0002] Wrinkle wiping paper is a special paper with high technical content and high added value. Wrinkle wiping paper, weight: 15-45 grams / square meter. At present, the domestic mainly relies on foreign imports such as Japan and the United States. Performance characteristics: no hair dust after wiping; efficient water and oil absorption capacity; soft texture, no damage to the wiping surface; good wet strength and solvent resistance. Application occasions: high-tech products such as wiping lenses, lenses, cameras, optical glass components, precision electronics, microscopes, mobile phone (computer) displays, etc. Currently, the use of imported paper mainly has the disadvantages of high paper prices and long delive...
