Production process of high-opaqueness carbonless carbon paper

Abstract

The invention belongs to the technical field of carbon paper, and particularly relates to a production process of high-opaqueness carbonless carbon paper. A coater adopted in the technological methodcomprises a paper rolling cylinder and a coating machine. The coating machine comprises a base, a shell and a discharging unit. The shell is installed on the base, and a discharging port is formed inthe position, close to the paper rolling cylinder, of the shell. The discharging unit comprises an air pipe, a first wheel, a second wheel, a push rod and a pressing rod. The side wall of the air pipeis provided with a diversion port pointing to the first wheel, so that the air pipe can blow the first wheel to rotate after ventilation; the push rod is slidably connected into the opening, and a rack is arranged on the side wall of the push rod and engaged with the second wheel; through cooperation of the base, the shell, the air pipe, the first wheel, the second wheel, the push rod and the pressing rod, coating is evenly smeared on raw paper, the production quality and the production effect of the carbon paper are improved, and the use effect of the coater is improved.

Description

technical field [0001] The invention belongs to the technical field of copy paper, in particular to a production process of highly opaque carbonless copy paper. Background technique [0002] Carbon paper is a kind of paper whose front is coated with an acid developer and the back is coated with microcapsules containing colorless latent dye. When the paper is overlapped, the microcapsules are broken due to mechanical pressure, and the colorless latent dye overflows and develops color when it encounters acid. , forming an image. This paper can be used in multiple stacks, and it is mostly used as a bill; while carbonless copy paper is a copy paper that does not need to be colored and waxed. When multiple pages of carbonless copy paper are stacked together, multiple copies of the document can be copied directly by printing or writing. Not only is it convenient and clean, but it can also be made into perforated blank computer printing paper to achieve efficient continuous print...

Problems solved by technology

[0004] In order to make up for the deficiencies of the prior art and solve the problem that the base paper with high opacity in the current carbonless copying paper cannot be copied or the copying effect is poor, and the opacity of the carbonless copying paper that can be copied many times is low, the invention proposes A production process of high opacity carbonless copy paper
