Embodiment Construction

[0011] The present invention will be further described below in combination with specific embodiments.

[0012] Negative ion paper contains no less than 1500 negative ion components per cubic centimeter of paper.

[0013] The preparation technology for preparing above-mentioned negative ion paper comprises the steps:

[0014] 1. Selection of raw materials: 800 kg of coniferous and 150 kg of hardwood pulp and 50 kg of high negative ion materials per ton of negative ion base paper.

[0015] 2. Softwood pulp → high-consistency pulper → No. 8 pool → high-consistency beater → No. 7 pool → disc refiner → No. 5 pool;

[0016] Hardwood pulp→medium consistency pulper→No. 6 pool→medium consistency beater→No. 6 pool→flaker→No. 5 pool→saw-type refiner→No. Protein-type light leaf salt and high molecular weight materials are mixed according to the weight ratio of 7:2:1), mixed pulp) → No. 3 pond, low sizing → No. 2 pond → No. 1 pond → double disc mill → paper machine copying Paper.

Abstract

The invention discloses a negative ion paper and a preparation process thereof. The negative ion paper contains no less than 1500 negative ions per cubic centimeter. The preparation process includes the following steps: adding negative ion occurring powder to wood pulp, the occurring powder takes up 5% in the weight ratio of all the paper; papermaking through a paper machine to prepare the finished product after mixing, sizing and twin-disc grinding. The inventive negative ion paper is characterized by wide application, low cost and simple process.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to negative ion paper and a preparation process thereof. Background technique [0002] At present, paper is used in many fields, but the application fields of each kind of paper are very narrow, such as food field and pharmaceutical field, and different papers must be produced to meet different requirements, which brings certain advantages to the application of paper. limits. Contents of the invention [0003] The purpose of the present invention is to provide a negative ion paper with a wide range of applications. [0004] The technical scheme that realizes the above-mentioned purpose of the invention is as follows: [0005] Negative ion paper contains no less than 1500 negative ion components per cubic centimeter of paper. [0006] Another object of the present invention is to provide a kind of preparation technology for preparing above-mentioned negative ion paper, and i...
