Decrypt the whole process of "Jade Polishing"!

Polishing powder: Diamond polishing powder is usually formulated with edible oil or water to form a paste. Other polishing pastes are generally chrome oxide in green and yttrium oxide in orange-red.

Jade polishing

1. Prepare a hanging mill like a small electric drill and a disc polishing machine as well as a vibrating polishing machine, which is generally suitable for large-volume polishing.
2. Prepare a set of diamond grinding heads (for decorative jade pieces) and jade strips and sandpapers. 3. Prepare a set of felt grinding heads and rubber grinding heads and polishing pastes, wool felts and leather and rubber sanding. Wheels and brushes, etc. 4. Prepare a set of round sandpaper and round cloth wheels. Polishing powder or polishing paste and glazing wax.
5. Prepare a set of diamond assorted enamel and fixing glue used for engraving.
6. Prepare some 600#---1200# polishing abrasives as grinding stones for hand polishing and vibration polishing machines.

The process is: first use a power tool to install a diamond drill bit to modify the jade piece, and then repair it with diamond assorted. Large-area grinding by coarse sand. Use a round cloth wheel to apply a polishing paste for large-area polishing. Polish the paste with a felt head for fine polishing. It can also be directly polished with a rubber grinding head. Finally, you can use the No. 1200 sand for manual throwing. This is related to the fineness of the jade piece, the thickness of the polishing material, the polishing speed, the strength of the polishing, and of course the jade. This is easy to find out in practice.

The first step: the paste, the surface of the carved jade is coated with a paste of polishing powder, the green is chrome oxide orange red is yttrium oxide.
The second step: push grinding, grinding the surface with a wheel of two thousand purposes.
The third step: repeat the first two steps, generally repeat twice.
Step 4: Apply the diamond powder to the surface of the emerald and then use a hard brush to throw it.
Step 5: Fine work, start to throw away small places that big tools can't throw. Use bamboo, dip diamond powder, use bamboo chopsticks bigger, use bamboo toothpicks in small places.
The sixth step: fine polishing, the jade is coated with diamond powder and then polished with hard skin. Most of the domestic use of cowhide, Myanmar mostly uses elephant skin.
The jade is thrown away, but there are still a few finishing touches to be done.
Step 7: Cleaning, the purpose is to clean the polishing powder remaining on the polished jade. It is mainly cleaned with an ultrasonic machine, and the place where it can not be cleaned is rubbed with alcohol.
Step 8: On the wax, the protection of the surface of the jadeite product can be washed off with boiling water.
The next step is to blow dry. A beautiful emerald will meet you like this.
Double effect, our approach is: after finishing polishing, paste the position without blasting with strong adhesive tape, then sandblasting, tear off the adhesive tape, and then put the edge part should be light water but also sprayed to the position, then Carefully use the bamboo stick to top the light, (or vice versa, then polish it, and see what you need to do.) Then the fine position needs to be fine-tuned (such as hook hair), then top light~`
