A kind of steel warm paper and its preparation process

Abstract

The invention discloses a steel warm paper and a preparation process thereof, and mainly relates to the technical field of papermaking. The thickness of the paper is 0.55mm and 0.57mm, the allowable error range of the thickness is ±0.015mm, and the tightness is 0.64±0.01g / cm 3 , Longitudinal ring pressure index 8.5±0.5N.m / g, interlayer bond strength 130±20J / m 2 , water absorption value (15s) 300±50g / m 2 , the paper moisture is 7.0 ± 0.2%; the paper tube base paper manufacturing process includes pulping, paper forming, rewinding, and then packaging, refining during the pulping, and adding auxiliary materials and fillers when forming the paper. The invention has the advantages of low cost, low tightness, built-in burrs, and low price, and can endow the paper tube with good hardness, rigidity, flame retardancy and the like after the tube is rolled.

Description

technical field

[0001] The invention mainly relates to the technical field of papermaking, in particular to a steel warm paper and a preparation process thereof. Background technique

[0002] With the rapid development of our country's economy, paper core and paper tube base paper products have the advantages of low cost, light weight, easy recycling, no pollution, no pollution, etc., and have been widely used in papermaking, packaging, textile and chemical fiber industries and other special industries. Applications. It can be used not only as the inner core of various webs and cardboards, but also as a textile bobbin for synthetic filament, polyester, polypropylene, spandex, etc., especially for the paper bobbin used in the textile industry has gradually replaced the tapered bobbin. While people are testing the quality of paper cores and tubes, the concept of technical requirements for the base paper used has also undergone great changes.
