Marble Grain Transfer Printing filmMake Stone waste to treasure

VeneeringStoneThe new process of "changing face" is to use a newStoneSurface treatment process to improveStoneResource utilization, which willStoneProcessing of all kinds of waste to treasure, to achieveStoneIndustry sustainable development, green recycling economy.

Developing green recycling economy and reducing waste of resources is the development policy and economic concept advocated by the Chinese government and various countries all over the world. The new technology of "face-changing" of the facing stone in this paper is to use a new stone surface treatment technology to improve the utilization ratio of the stone resources, to treasure the "problem products" and to realize the sustainable development of the stone industry and the green circular economy.

Processing technology of stone "face changing"

It is understood that there are two kinds of "problem" to waste the new technology-sticker method, water transfer printing method.

First, the sticker method "face" processing technology--Marble Grain Transfer Printing film

The so-called "sticker method" processing technology is directly in the "problem product" to paste a layer of design patterns in advance, most are imitation natural stone color, texture, wood color, texture of decorative material colored paper, or "problem products" into the required surface modeling style, on top of it glued to a layer of prior design patterns of colored paper , and then brushing a layer of resin on the sticky sticker to form a new deep processing technology for protecting and enhancing the texture and luster of the surface.

Sticker method has large board sticker products, circular plate sticker products, line stickers products, cylindrical (solid cylindrical and hollow cylindrical) sticker products.

  ★Marble Grain Transfer Printing filmProcess：

1. Material selection

Select the stone material that is suitable for processing and pasting paper products. The selection of materials requires less crack, sand hole, holes, small deformation of any marble materials, color difference is not limited; artificial marble material is the most suitable for processing paper line products, because man-made marble materials without cracks, no sand holes, the use of man-made marble material does not need to be reinforced, sand holes, hole surface sealing treatment; Granite materials can also be used to paste paper processing, but granite materials because of high hardness, difficult to shape, difficult to polish, in the production and processing efficiency is low.

2. Open Blanks

The selected blocks and scraps are turned into blanks of the thickness required for processing. If there is a ready-made thickness of the blank, this procedure can be omitted. For more cracks in the material, open the billet should pay attention to avoid the crack direction or along the direction of the crack, do not vertical crack direction, or open to the blanks are cracked, resulting in all material fracture.

In order to prevent the cracks of the blanks in the cutting plate, pieces of broken, in advance to the billet with a strong fiber net for reinforcement, if necessary, reinforced reinforcement.

3. Cutting board

Cut the selected material into long and wide dimensions to be processed. Considering the particularity of the processing technology of the sticker products, it is suggested that the processing length of the paper products should not exceed 1500mm and the man-made marble should not exceed 3000mm. Natural marble more than 1500mm easy to break, man-made marble more than 3000mm easy deformation, the specific processing of how long the most suitable to the material does not break, deformation for the principle.

4. Rubber replenishment, reinforcement

This process requires special attention to the natural marble material which is easy to break, surface crack, hole and sand holes. Carry on the glue to strengthen, make it in line shape, coarse grind, fine grind does not break, after finishing the finished product does not break; on the surface sand hole, hole sealing treatment can avoid the product surface sticker after the drum or sag.

5. Product modelling, coarse grinding, fine grinding

① line product modeling, coarse grinding, fine grinding

Using the automatic line machine equipped with 40#, 60#, 120# and 220# diamond forming wheels, the blank is molded, coarse grinding and fine grinding. Requires smooth surface, no waves, no traces. The smoother the surface, the more flat the sticker surface.

② Circular plate product modelling, coarse grinding, fine grinding

Follow the stone such product modelling processing technology, only the sticker product must use the circular plate coarse grinding machine, the full automatic ARC board grinding polishing machine fine grind to no less than 220#, in order to obtain very smooth, radian smooth surface.

③ Solid column molding, coarse grinding, fine grinding

Follow the stone products such as molding processing technology. The light body solid column preferably uses the rotary mechanical equipment to grind, causes the cylinder body surface to be very smooth, radian smooth, the shape of the column foot, stigma as far as possible to use the geometric shape of simple, less groove, "V" groove, R10 the following convex arc, because the surface shape of the complex not only increased the difficulty of the sticker and production time, more impact on the surface of the paper substrate roughness.

6. Cleaning and Drying

Clean the line with diluted cleaning solution to eliminate any material that affects the adhesion of paint and paper on the line surface.

Dry the surface of the paper line to remove moisture from the line surface.

7. Surface Treatment

The surface has holes, dents, cracks in the "problem product" with the cloud stone rubber filling formation, rubber repair treatment. This step is not required for surfaces that do not have similar lowlands defects. If necessary, to get a smooth surface, you can spray primer.

8. Sticker

Prepare the appropriate coloured paper as needed, from the market or professional manufacturer.

In the back of the paper paint the right amount of waterproof adhesive, the use of professional equipment to crush the substrate to see the smooth surface.

The general use of the coating machine will be printed with natural stone patterns or wood patterns of paper affixed to the line. Require the paper to be flat, attaching strong force.

9. Glue

On the whole of the attached paper on the surface of the coating, brush coating or spraying thickness up to 1㎜ resin layer.

The resin is sprayed with automatic spraying equipment onto the line of the sticker. You can also manually apply the resin brush to the line. The quality of the brush requires smooth, no bubbles, needle, pores, glue accumulated thickness is basically the same. The thickness of the rubber layer is suitable for 2~4㎜.

Gelatinize is the most important process of resin surface sticker products. The quality of the gelatinize determines the quality of the product.

Coating the best use of automatic spraying technology, not only spraying the product quality is very good, spraying efficiency is very high, more important is to avoid contact with the glue substances, to protect the physical and mental health of spraying personnel.

10. Line Molding

After brushing the plastic line because the glue along the shape of the flow, will appear in the Lowlands place glue gathers phenomenon, causes the gum here to be thick and causes the line shape not to conform to the processing shape request, therefore needs to have brushed the line to carry on two times modelling to eliminate the rubber accumulation the error which produces.

When the line is molded, the forming wheel of 120#, 220# and 320# is installed on the line machine, which completes the line forming, coarse grinding and fine grinding work.

11. Sanding Fine Grinding

The brush over the plastic line sanding processing. Sand light makes the surface of the sheet smooth while increasing the strength of the surface, uniform thickness.

12. Polished and polished

After the surface resin curing polished.

With fully automatic line polishing machine finish the polished line.

13. Waxing

If you want to improve the brightness of the line, you can use hand-powered polishing machine to wax and then add light to the line.

  ↓

14. Inspection

Inspection by the inspectors according to the inspection standard of the line and the inspection requirements of the sticker line.

  ↓

15. Flexible Packaging

The coated machine is used to foil the processed line products to prevent the products from being scratched and damp.

16. Warehousing, entering warehouse

By the relevant staff handling products into the warehouse warehousing procedures, handover good product model.
