4. Huahuakou operation and requirements

The cutting process of the book block has a stenciling process in addition to the rolling gold mouth. The flower mouth is much more complicated than the rolling gold mouth. The quality requirements are quite strict. It is required to be made once in operation, and there is no room for rework.


1) Huahuakou materials and formula


1 materials: including adhesive materials and color materials.

Adhesive: diluted with hydrochloric acid (bottom binder), water, flour paste, sea creatures.

Coloring materials: yellow, red, blue, and fresh cows.


2 preparation.


▲ color material preparation,


a. Take several colors of equal weight. Each coloring material is ground into a fine powder with porcelain crucible or copper crucible (the finer the better, there must be no particulate matter). Do not mix colors when grinding. Clean the dish after each color is polished. The ground powders are separately packed in a transparent container for use.

b. Put the fresh cow bitter (select one or two according to the dosage) in the container, do not add water, stew with water (about 10 minutes after the water is boiled), and then distribute it evenly into 3 colors (1 fresh The bovine bitter gallbladder is mixed with 15-25 g each color and immediately stirred for use.


▲Binder preparation.


There are two kinds of adhesive materials, namely, bottom adhesive and color adhesive. The role of the bottom adhesive is to make the colorant firmly adhere to the slit; the role of the color adhesive is to stick the color to the surface when it is sticky.


a. Bottom sticking material: Take 1/4 hydrochloric acid solution and 3/4 water to mix and stir evenly.

b. Color-adhesive: Mix the flour and sea-buckthorn with water, dilute and heat, and boil it into a fine mucus (the viscosity is slightly thicker than the sweeping).


▲ ingredients requirements.


a. The ingredients of various materials should be properly adjusted to ensure that the flower mouth is firmly bonded;

b. Take a little test before the ingredients, and then add the amount after the preparation, to avoid waste caused by not meeting the requirements;

c. It is necessary to strictly maintain the purity of various color materials and ensure the correct color of the flower mouth.



2) Tools and use of Huahuakou


1 rectangular container box (with white iron or aluminum skin inside the wooden box), the box is 800mm long and 300mm wide. The box is divided into two sections, one section is 600mm long, used for storing paste adhesive, and the other section is 200mm long. It is used for storing the remaining material after the crucible, and the two sections are separated and cannot be mixed.

Storage container box

A: Container box B: Needle dice C: Scratch D: Wood stick pattern


2 ordinary sheep brush 3 (one for each color, can not be mixed), used for color.


3 One 3-pin tweezers (made with a large needle), the length is 2-3 times the thickness of the book block, used to paint mixed patterns.


4 small round wooden stick, about 120mm long, the diameter can be large or small, the diameter of the pattern is small, and vice versa, 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 water pipe with a large pressure to prepare the color after use.


3) Operation process and requirements of the flower mouth.


The book core flower opening should be carried out after cutting, but it is not possible to cut the light once with a three-sided knife. It is necessary to cut one side to avoid the color from staining other incision surfaces, causing the flower pattern to be messy. The process is as follows: preparation work before the sputum → coating the adhesive material → painting the color material → sputum flower mouth → washing → natural drying → inspection.

Before using the flower, you should prepare all the materials and tools, and do not miss one of them to avoid continuous processing due to lack of leakage. The operation must be absolutely correct and correct, and must not stop in the middle, in one go.


1 spare material and tool placement position.


a. The container box storing the paste ingredients is placed on the right side of the front panel of the operator; the color brush, the needle, and the round stick are placed on the lower right side of the container box;

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

c. Three color material containers with cow bitter are placed on the front upper side of the container box in the order of their use;

d. Place the water pipe used for the coloring material in the operator's convenient position, and prepare the water storage container or water pipe.


After all the utensils are ready, the flower mouth can be operated.


2 folder on the bottom material.


Use two thin plastic plates or planks (same size as the book block) to clamp the bookcase on the cut side (preferably tightly), the slits are flush with the splint, and must not be convex or recessed.


After the book core clamping clamp is neat, apply a layer of dilute hydrochloric acid mixed solution along the incision surface, and then dry it to dry the flower mouth.


Operation requirements: only 1 copy per 蘸, each clamping degree should be basically the same, clamped and clamped, not loose and detached; the primer should be evenly applied, the texture of the brush should be soft, and no debris should be applied to the slit. On, ensure that the cut surface is neat.


3 painting colors.


Paint color refers to the operation of applying the various color materials to the incision with a brush. After the primer is applied, use the natural dry time, draw the appropriate 3 kinds of color materials with a brush, and draw the color on the surface of the paste in the container of the adhesive storage container. The length should be more than 1.5 times the length of the book block, and the width is 2-3 times the thickness of the book block (the width of the book back). After the three colors are drawn by color, use a round wooden stick to regularly stir up and down on the paste with 3 colors (mainly stir the surface of the color, can not stir and destroy the pattern), to be mixed with 3 colors After forming a thinner color strip, the pattern of the pattern is drawn in the left-right direction (the length direction of the storage box) by the needle shank.


Regardless of the color, the agitation or the pattern, you must use a uniform force, and you can't pause in the middle (if you stop regularly, it does not affect the effect of the pattern).


After the above work is completed, the booklet incision of the good primer is also dried, and the flower mouth can be smashed at this time.


4 Huahuakou.


For the book block with good primer and natural drying, hold both ends (the head and the foot) with both hands, and put the cut face down to draw the colored storage container box, so that the surface of the cut is smeared through the colorant. Paste the adhesive, let the incision stick to the pattern color, and then remove it immediately, that is, complete the sticky operation.

Operation requirements: After the book core incision is placed in the colored paste, it must not move. The movement should be smooth, avoiding the pattern being disturbed after the movement; the contact surface of the book core incision and the color paste should be uniform, and the material should not be too deep or too It affects the processing of other incision surfaces and the quality of the color surface. After the completion of a book, the colored paste paste can not be glued again. It should be scraped into a small container box with a scraper and then repainted. The next processing can be carried out at the rear.


5 rinse.


Flushing refers to the operation of flushing off excess paste paste on the cut surface of the crepe squeezing port with clean water. ,

Immediately after rinsing the flower mouth, flush the incision adhesive with water spouted from the flat nozzle hose until all the adhesive on the flower mouth is completely washed away. After the rinsing of the flower mouth, the color pattern is bitten and stuck on the incision, the pattern is clear and regular, neat, clean and beautiful, and artistic. After the cutting is dry, the splint can be removed, and the whole process of the flower mouth is completed.

Operation requirements: the flushing water pipe nozzle should be flat, and the water pressure should be flushed; the water sprayed from the water pipe should have a certain angle with the flower mouth surface, and should not be flushed or flushed into the book block or other surface. When washing, check whether the book block is clamped. If there is slack, it should be tightened in time to avoid infiltration into the book block when flushing. After washing, the book block should be completely dry before being opened. If you want to process other surfaces, cut and clamp them in sequence to complete each step and complete the one or only side of the flower.
