Problems solved by technology

However, due to the use of acidic papermaking technology in the traditional printing paper manufacturing process, it will cause great pollution to the environment
And in the subsequent process of printing pictures, ammonia nitrogen gas will be produced, which will further cause damage to the ecological environment and human body
At the same time, the printing operation is cumbersome and the production cost is high, which cannot meet the needs of large-scale use of high-speed engineering drawings

Abstract

The invention relates to the field of papermaking, specifically a production process for engineering copy base paper, which can replace the print base paper. Treatment agent, brightener, pigment, sizing agent, filler, etc. are mixed, and then sprayed to the wire part for dehydration through the headbox, and then dehydrated by pressing, drying in the front drying area, sizing by the surface sizing machine, and post-drying area After drying, calendering and finishing, the finished product is obtained by coiling. Compared with the prior art, the paper of the present invention has the characteristics of high strength, good stiffness, low water absorption, low expansion rate, etc., and can well meet the use requirements of high-speed and wide-format drawing copying and printing. Used in high-speed copiers, the printing effect is good, and it can completely replace printing paper.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a production process of engineering copying base paper, and the obtained engineering copying base paper can replace printing base paper. Background technique [0002] Printing paper, also known as "blueprint paper", is a kind of chemical coating processing paper specially used for various engineering design and mechanical manufacturing printing, which is indispensable in production, scientific research and construction. Usually use ferricyanide and iron salt sensitized paper or cloth, rinse and develop with clean water after exposure, the photo paper with blue background and white picture, especially for printing maps, mechanical drawings, architectural drawings. However, due to the use of acidic papermaking technology in the traditional printing paper manufacturing process, it will cause great pollution to the environment. And in the subsequent photo printing process, ammonia nitroge...
