Marble production process and process

Stone processing is varied, flat processing, heterosexual processing, parquet processing, sculpture processing. Different uses of different processing methods, to organize the processing of stone, today let's talk about the processing method of stone flat plate!

Flat plate processing

01

Sample confirmation

Stone sample confirmation, also known as stone sealing, sealing sample should be confirmed as follows: species (stone name origin), texture, color, texture and grade. Sealed samples can ensure that the design effect of the full presentation, is the final quality of the project reasonable guarantee.

02

Wasteland Inspection

Wasteland Inspection needs to have a wealth of experience in the stone industry, need to have enough knowledge of the stone. Barren material inspection in addition to meet the requirements of sealed samples, to take care of the finished specification to improve the output rate, but also based on experience to avoid unfavorable factors.

The barren material inspection is divided into mapping inspection and pre-purchase inspection. Inspection of the use of spray cans, tape measure, flashlight, carefully record the inspection of the barren material information, in order to prepare for the use of procurement

03

Barren material procurement

Barren material procurement before the barren material inspection results with the designer or the owner to fully communicate, to obtain recognition. Carefully count the quantity of stone used.

The quantity of barren material + the quantity of finished products / output rate + 3% spare quantity

When purchasing the barren material, combined with the specifications of the finished product, select the qualified barren material with relatively high output rate. After purchasing the raw materials, we will arrange the logistics to transport them back to the factory in time.

04

Frame saw cutting

Before cutting, mark the tangential direction and thickness; then adjust the saw pitch according to the planned thickness of the slab; fix the barren material on the ferry. Opening, to control the knife speed, limestone 30cm / h, marble 10-20cm / h. Stone hardness is high, to observe the cutting situation, to prevent the occurrence of running knife phenomenon. After opening the material, it is necessary to prepare the barren material number, rack number and plate number in time.

05

Drying

Stone slab drying, in order to guarantee the quality of backscreening and gluing surface operations. Only when the stone is sufficiently dry can these two processes be carried out.

06

Back net

Back net is used for the back of the stone to reinforce, waterproof, anti-drumming effect.

07

Scraping adhesive

Natural stone surface often has many trachoma, cracks and even holes, affecting the stone quality. By scraping the surface glue to make the surface more perfect. After scraping glue need to wait for the surface glue completely solidified, usually using drying line operation

08

Polishing slab

Except for yellow granite using manual hand grinding, marble are using automatic polishing line operation.

09

Slab Inspection

Marble polishing, its gloss requirements > 80 °; flatness < 0.3mm; thickness ± 1mm

10

Slab Scan

Scanning of the slabs can be presented to each piece of slabs of the plate surface of the real situation. This helps in the "utilization planning" of the next process.

11

Use Planning

Large slab use planning is conducive to: fully exploiting the beauty of the stone; avoiding or cleverly utilizing the natural imperfections; and increasing the yield rate.

12

Positive lamination

13

Cutting engineering board

Cutting engineering board using infrared bridge cutting machine. The length and width error should be <0.5mm, the angle error should be <0.3mm. cutting should be different from stone to stone, use the appropriate cutter, control the correct knife speed, to prevent the running knife, chipping, falling corner and other phenomena.

14

Secondary processing

Secondary processing of engineering boards, such as: bonding, cutting corners, back inverted, positive inverted, slotting, grinding modeling edges, antique surfaces, carved surfaces and so on.

15

Inspection of engineering board

Inspection of engineering board is as follows: specification size, quantity, appearance quality and number.

16

Stone protection

Stone protection means that, after the stone is dried or dried, the protective agent will be evenly applied to the six sides of the stone to achieve waterproofing and stain prevention.

1, water absorption >1% (tuff, limestone, sandstone): the bottom side of the use of Aidi adhesive, the side of the use of sealants, the front side of the use of solvent-based protective liquid.

2, water absorption rate <1% (serpentine, dolomite, calcite): the bottom side of the use of Aldi adhesive, the side of the use of sealants, the front side of the film.

3, translucent jade class to film the rest do not need, but construction should pay attention to the phenomenon of color change.
