Template instructions
Dear customer, thank you for using the stainless steel hot-pressed template made by our company. Please read the instructions carefully before using in order to better understand the performance of the steel plate and maintain it correctly to achieve the best use effect.
1. Packaging and Transportation
1. When transporting, use a special packaging box and make a sealed moisture-proof packaging. During the transportation process, the packaging box should be laid flat and fixed, and it is strictly prohibited to stack heavy objects on it. Before opening the box, the user should check whether the packaging box is intact. If there is any damage, please notify our company immediately and make a record of the number of each template.
2. The operator should wear clean leather gloves or glove free of debris in every link of unpacking, transportation and installation, and at the same time use 3-4 layers of gauze to hold in the palm of the template at the four corners and lift at the same time . It is strictly forbidden to drag or collide to damage the template.
Second, the installation, pretreatment and use of low-pressure formwork
(1) The new template used for the first time should be cleaned with cotton wool and a detergent diluted with hot water, washed and dried. Four points to note when installing:
1. It is better to have a card slot on the suspension device, which is convenient for adjusting the position of the template. 2. The cushion must be flat.
3. Avoid oil and debris during installation. 4. If a tensioning device is used, the expansion factor must be considered.
(2) Template pretreatment process:
1. When the template is used. The surface is coated with a mold release agent or special silicone oil (our company has a special mold release agent), which allows it to penetrate into the capillary pores of the template during repeated temperature changes, thereby forming a fine and strong mucous membrane.
2. Lay one to two layers of white paper on the working surface close to the template, and then two to four layers of cowhide in the middle (use unimpregnated base paper).
3. Close the hot press to increase the temperature step by step under the premise of no pressure, 30℃-60℃-90℃-120℃-150℃-180℃, repeatedly back and forth for more than 20 minutes to the highest temperature, and then naturally cool, add Press to 20-30kg/cm2, and finally turn on the hot press.
(3) When using the template, make sure that the template and the overlay are accurately aligned and eliminate the residue of melamine in a timely manner. Regularly check the fasteners on the vacuum suction device and provide a production cycle to clean the template to eliminate solid buildup. The resin and stains maintain its gloss.
(4) For the production of laminate flooring and melamine decorative panels, special chrome-plated templates with high surface hardness and good durability should be used.
3. Installation, pretreatment and use of high-pressure formwork
High and low pressure templates have similar characteristics, but there are differences in the use process:
1. Pay attention to three points during installation: ① The size of the template in each layer of hot pressing plate should be the same ② The template of each layer is flat, such as mirror surface, pitted surface, and relief can not be mixed ③ The surface mounting mechanism should make each layer of template fall accurately on the hot press Plate in the middle.
2. Pretreatment: ① Evenly apply a release agent on the front of the template, spread one or two layers of white paper on the front and back of the template, and then two or four layers of kraft paper (original paper) ② Close the hot press without pressure Under the premise, the stage temperature rise is carried out, 30℃-60℃-90℃-120℃-150℃-180℃, repeatedly back and forth for more than 30 minutes. Up to the highest temperature, then naturally cooled, pressurized to 80-100kg/cm2. ③ In the process of using templates, each template should be stacked neatly. Clean the dust on the template before loading paper. The vacuum suction cup should be wrapped with gauze and eliminate the suction cup marks on the template.
4. Use of templates in other production occasions
The stainless steel plate (usually using mirror formwork) used for cutting veneer veneer, bamboo plywood multi-layer building template, etc. should be cleaned after unpacking. Apply the release agent and preheat the board using the above method. The formwork hoisting should be careful to avoid damage.
Five, storage and maintenance
1. Spare or stored template, clean the board with cleaning agent, spray a layer of mold release agent after drying, lay it flat and cover it with dustproof cloth, close to the ventilated place.
2. When the sticky board is found, the template should be removed in time, soaked in boiling water to soften the residue, then cleaned, and sprayed with a layer of release agent after drying.
3. The template should be cleaned regularly. When cleaning, it should be placed on the working platform. After the cleaning agent is soaked in warm water, scrub with absorbent cotton, put some decontamination powder in the stained area, scrub it clean, and rinse it to dry. You can also heat the template in the sink or cook it before removing it.
4. If the template is found to have slight scratches, the coating is peeled off and worn, it will be sent to our company for repair; if there is a bulge, pit, indentation, or wave deformation, it will be sent to our company for pressure repair.

Problem
|
Reason
|
Approach
|
|
Sticky board
|
1. The melamine resin formula is not suitable. 2. The hot pressing period is too short or too long. 3. The cured adhesive sticks to the pores of the template.
|
1. Check the dipping period and reactivity. 2. Adjust the hot pressing process.
3. After the hot water is heated, use the decontamination powder and acetone to clean, dry and spray the release agent.
|
|
Different colors appear on the template surface
|
Inferior ink on decorative paper is transferred on the template
|
Clean with detergent and detergent
|
|
Decreased gloss of plywood
|
Resin residue, stains
|
Clean regularly with detergent and detergent
|
|
The template is all bluish or partially bluish
|
1. The water used for impregnation contains excess calcium metal. 2. The heating platen inside the heating pipe is blocked.
|
1. Clean with acetic acid. 2. Clean the hot pipes.
|
|
Chromium layer falls off
|
1. Mechanical damage. 2. Improper installation. 3. Corrosion.
|
If it is a new steel plate, please contact the supplier, otherwise please send it back for repair
|
|
The template is worn and shiny around
(When pressing the laminate floor)
|
Due to the sudden expansion of the long-term base plate and surface material (including alumina),
Produces a strong friction effect, and makes the periphery of the substrate contact with the template to produce scratches.
|
Renovation: dechrome, polish, soft light, re-chrome. If you continue to use it, it will destroy the substrate of the board and require a full renovation.
