Detailed description of luxury hardcover - processing technology (4)

3-pin tweezers (available in large size), 2-3 times the length of the book block, used to paint color mix patterns.

4 a small round stick, about 120mm in length, diameter can be large or small, the pattern of its small diameter should be small, on the contrary to be large, can be selected according to requirements.

5 Connect the flat nozzle water pipe (similar to the ultrasonic nozzle) to the water pipe, that is, use a high-pressure water pipe to prepare for flushing after finishing the flower mouth.

3) The operation process and requirements of the flower mouth.

The core of the book block must be cut after cutting, but it is not possible to cut the light once with a three-sided knife. Cut one side of the book block to prevent the other side of the cut from being stained, resulting in messy patterns. The process is as follows: preparatory work before painting → sticking material → painting color material → flower opening → washing → natural drying → inspection.

All materials and tools should be prepared before opening the mouth, and one of them must not be missed to avoid continuous processing due to lack of leakage. The operation must be absolutely correct and correct. It must not be stopped halfway.

1 spare material and tool placement.

a. The container box with the paste ingredients is placed on the right side of the operator's front workbench; the color brush, needles, and round sticks are placed on the lower right side of the container box;

b. The container of hydrochloric acid plus water is placed on the left side of the container box;

c. Three color containers equipped with bovine gallbladder are placed on the front upper side of the container box in the order of their use;

d. Place the water pipe used for flushing the colorant in an easy-to-hand position by the operator and prepare a water storage container or pipe.

After everything is ready, you can do it.

2 book on the end of materials.

Use two thin plastic plates or wooden boards (the same size as the book block) to clamp the light-cut book block (preferably tied tightly) with the incision flush with the splint and not to protrude or recess.

After the book block clamps are neat, smear a thin layer of dilute hydrochloric acid along the cut surface. After the skin has dried naturally, it can be glued.

Operation requirements: Each time only one folder is clamped, each clamping degree is basically the same, the clamps are clamped together, and they are not loosened and detached; the primer is to be applied evenly, and the brush texture should be soft, without any foreign matter applied to the incision Above, ensure that the cut surface is clean.

3 color.

Coloring refers to the operation of applying the colored materials to the cuts with a brush. When the primer is applied, use its natural dryness time, apply three kinds of colorants with a brush, and paint it evenly on the surface of the paste in the adhesive storage container box. The length should be more than 1.5 times the length of the book block and 2-3 times the thickness of the book block (back width of the book). After the three colors are painted in a color-coded manner, a circular stick is used to regularly and agitate the three-colored paste (the surface of the main stirring color cannot be disturbed to disrupt the pattern), and the three colors are to be stirred. After forming a fine stripe, a pattern with a pattern is drawn in the left-right direction (longitudinal direction of the storage box) with a needle weir (Fig. 7-1, see above).

Regardless of the color of painting, stirring, or patterning, we must use force evenly, and we can't stop halfway. (If there is a regular pause, it will not affect the pattern effect.)

After the above work is completed, the cut-out of the book block core with good material is already dry, and at this time, the flower opening can be made.
