Embodiment 1

[0024] 1) Printing: Automatically rewind special tape rolls with a width of 700-720mm and a thickness of 0.08-0.09mm, and adopt an ultra-low cylinder tension detection closed-loop control system to quickly adjust the paper tension and control its accuracy at ±0.3mm. The printing machine is coated with special label ink, the printing error is controlled at 0.17-0.30mm, and the color thickness is controlled at 0.01-0.02mm. The obtained tape paper is put into a fully enclosed oven for external steam heating and drying. The drying temperature is controlled at 70-75°C. A good printing tape paper reaches a stable printing tension through the above-mentioned ultra-low cylinder tension detection closed-loop control system, and is then rewound;

[0025] 2) Coating: Roll up the tape paper roll that has been printed as described in step 1), and use water-soluble glue at 10-15g / m 2 For the tape paper completed in step 1), the coated tape paper roll is dried by hot air circulation, and the...

Embodiment 2

[0028] 1) Printing: Automatically rewind the special tape roll with a width of 720-750mm and a thickness of 0.08-0.09mm, and adopt an ultra-low cylinder tension detection closed-loop control system to quickly adjust the paper tension and control its accuracy at ±0.3mm, After the printing machine is coated with special label ink, the printing error is controlled at 0.17-0.30mm, and the color thickness is controlled at 0.01-0.02mm. The obtained tape paper is put into a fully enclosed oven for steam external heating and drying, and the drying temperature is controlled at 75-80°C. The dried printing tape paper reaches stable printing tension through the above-mentioned ultra-low cylinder tension detection closed-loop control system, and is rewound;

[0029] 2) Coating: roll up the tape paper roll that has been printed as described in step 1), and use water-soluble glue at 15-20g / m 2 For the tape paper completed in step 1), the coated tape paper roll is dried by hot air circulation...

Embodiment 3

[0032] 1) Printing: Automatically rewind special tape paper rolls with a width of 750-800mm and a thickness of 0.09-0.10mm, and adopt an ultra-low cylinder tension detection closed-loop control system to quickly adjust the paper tension and control its accuracy at ±0.3mm, After the printing machine is coated with special label ink, the printing error is controlled at 0.17-0.30mm, and the color thickness is controlled at 0.01-0.02mm. The obtained tape paper is put into a fully enclosed oven for steam external heating and drying, and the drying temperature is controlled at 80-85°C. The dried printing tape paper reaches stable printing tension through the above-mentioned ultra-low cylinder tension detection closed-loop control system, and is rewound;

[0033] 2) Coating: roll up the printed tape paper described in step 1), and use water-soluble glue at 20-25g / m 2 For the tape paper completed in step 1), the coated tape paper roll is dried by hot air circulation, and the drying temp...

Abstract

The invention discloses a production process for a special paper adhesive tape for a gypsum board with a paper surface. The production process comprises three working procedures of printing, coating and slitting. The process adopted by the invention is good in printing quality, and can meet the requirements of thickness and strength of the adhesive tape at the same time. Wet sizing is achieved in the process of coating. The method of circulated heating and drying by hot air at upper and lower layers is adopted. Different temperatures are set according to vehicle speeds. The heat exchange is more sufficient to enable the coated adhesive tape paper to dry more rapidly so as to guarantee the longitudinal and transverse strengths of the coated adhesive tape paper. The procedures are simple and easy to operate. The end product is good in quality; and the occurrence of defective products is avoided. The fully closed oven negative pressure design is adopted for the dried part after printing. A heat source is reused for the second time, the energy is saved, the production cost is lowered, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a production process of paper tape, in particular to a production process of special paper tape for gypsum boards. Background technique [0002] At present, the layers of edge banding tapes used by gypsum board manufacturers are uneven, and the thickness and strength of the tapes used by most companies cannot meet the requirements of use, and the printing quality is poor, the color and pattern errors are large, and the appearance quality of finished products after edge banding The appearance requirements cannot be met, and wet water sizing cannot be realized. Only glue can be added online, and the tape after edge banding is easy to fall off. Contents of the invention [0003] In order to solve the problems in the above-mentioned prior art, the present invention provides a special paper tape manufacturing process for gypsum boards, which is coated by wet water sizing, and meets the requirements for the thickness and strength o...
