Jade hand -polished preparation materials: 1500 sand strips and sandpaper, 240 sand strips, 320 (360) coarse sand and cowhide.
1, first grind the rough 240 sand strips on the iron sand plate. Then use the rough sand strips to polish first.
2, use 320 (360) coarse sand to do it for the second time to deal with it for the second time. After the processing is completed, the carved knife marks have disappeared, leaving only the sandbrican to polish marks.
3, use 1500 sand strips and sandpaper, rub it very gently. After the completion, the baby's cracks can be seen basically.
4, use 2000 sand strips and sandpaper, rub it very gently, do not force it, if it is strong, it is easy to leave the trace of sand strips for the baby.
5, in the end we took a piece of cowhide, rubbed the baby hard, and the jade mirror polished was completed.
The first: prepare some polishing sandpaper with 600#--- 1200#as a hand-polished. (Because of the amount of consumption, it costs it)
The process is:*First use the electric tool to set the diamond drill to modify the jade parts, and then use diamond cashiers to repair it meticulous. *Use round sandpaper (from coarse sand fine sand) for large -scale grinding. *Use a round cloth wheel to apply a polishing paste for a large area of polishing. *Use a felt grinding head to apply a polishing paste for detailed polishing. *You can also use the rubber head to polish directly. *Finally, you can use No. 1200 sandpaper for manual throw.
The second type:
The first step: apply the surface of the carved emerald with a layer of paste -shaped polishing powder. The green is oxidized with chromium orange -red.
Step 2: Push, use 2,000 destinations of sand wheels to grind the surface.
The third step: repeat the first two steps, generally repeated twice.
The fourth step: apply the brush, apply the diamond powder to the surface of the emerald and then throw it with a hard brush.
The fifth step: fine work, start to grind the small places where the big tools cannot throw. Use bamboo, dipped diamond powder, and make bamboo chopsticks in large places.
Step 6: Square throwing, apply the jadeite with diamond powder, and use hard skin to grind. Most of the domestic leather, Myanmar mostly uses elephant skin. Emerald is tossed, but there must be a few jobs to do.
Step 7: Cleaning, the purpose is to clean the polished powder on the polished emerald. Mainly use the ultrasonic shift machine to clean it.
: The eighth, the protection of the surface of the emerald finished product, can be washed off with boiling water, and the next step is blowing dry. A beautiful emerald just meets everyone.
The third type:
The carving polishing process of jadeite --- Emerald hardness is high, but as long as diamond or artificial diamond tools plus speed can be carved at will. It is not simple to polish to glorious people. There are three most basic processes: a. Rough grinding-(1000-2000 mesh) Vajrayana is made into various shapes and tools to be carefully polished and smooth. b. Fine grinding-use (1600-1800 mesh) Vajra sand with the above method to polish and cause smooth and shiny. c. Right-use half-lifetime cowhide making tool dipped in polishing powder (2800-3000 mesh diamond powder) repeatedly friction, making the emerald products shine inside and outside. d. Passing wax-overwax is for waterproof, preventing dirt pollution.
The fourth type: no machine polished the jade
1. Prepare the following things: one section of waste leather belt about 8 cm long; 600#, 1500#water sandpaper; jade polished powder powder powder; jade polishing powder
2. Use 600#, 1500#water sandpaper to polish the jade wares until the grinding marks are not visible.
3. Cut a mouth of one end of the belt section to make it a "human" shape.
4. Put an appropriate amount of polishing powder into the water scoop, add a small amount of water, and adjust it into a paste.
5. Use the open end of the belt section to dip the polished powder paste, pinch the other end of the belt section, apply the polished powder to the jade articles, and repeatedly rub it to the light of the jade.
6. The polishing process should keep the polishing powder paste. If it is too dry, you can add an appropriate amount of water.
Bar -shaped solid mills made of abrasives and binding agents. Oil stones are usually refueling and lubricating when used, hence the name. Oil stones are generally used for manual grinding tools and parts, and can also be packed on the machine tool for honing and super fine processing. There are two types of oil and natural oils. There are two types of structures due to different abrasives used. ① The inferior oil stones made of rigida or silicon carbide abrasive and binding agent can be divided into square, rectangular, triangular, knife -shaped (wedge), circular and semi -circular oil stones according to their horizontal section shape; Or cubic boron nitride abrasives and binding agents with matrix oil stones, including rectangular, triangular and curved oil stones. Natural oil stones are processed by natural quartz rocks with delicate texture and grinding and polishing capabilities. It is suitable for hand -made precision grinding in the manufacturing industry such as precision machinery, clocks and tools.
has six types of oil and stones: green silicon, Bai Gangyu, palm -mounted jade, boron carbide, ruby (also known as sintering jade) and natural jade.
The boron -carbonized oil stones: The particle size is between 400 and 1000. The smaller the particle size, the greater the grinding amount. Covering the natural cornorite: It is the thinnest granular size in the oil and stone, but it is only used for polishing, and there is almost no grinding amount. After applying the W0.5 diamond grinding paste on the oil stones, the surface of the knife can be grinded into a mirror ruby Oil stones: between boron carbide and natural jade, the particle size is between 1000 and 2000, mainly used for blade, sharp blade mouth sharp, plus the W0.5 diamond -developed grinding can also achieve the effect of mirror surface. In addition, about diamond stone. The grinding paste, the granularity from W40 to W0.5, W40 is the thickest, and the amount of grinding is large. W0.50 is the thinnest. It is used for polishing, and it is not annealing.
Generally, jade should be polished before waxing. Let's introduce how jade polished.
The jade polishing process is actually a fine grinding operation. Jade polishing involves polishing agents and polishing tools. The polishing agent is mixed with certain liquids such as water and sewing oil in a certain percentage, so that it is attached to the polishing tool and rubbing with the workpiece. If the jade polishing operation method is proper, the jade piece can show a beautiful appearance.
It jade polishing process is to be attached to the polishing tool to achieve friction with the jade. Ordinary polishing tools are divided into two categories. One is used for polishing gear, spherical surface, and jade parts of the surface of the surface. It usually uses felt, leather, woolen, etc. Class is used for polishing jade parts with flat planes. It usually uses high -resistant hard materials such as metal, plastic, wood, etc. to make polishing discs. The polishing disk made by metal is called a hard disk, wood, plastic and even asphalt -made polishing disks are called medium hard disks.
It, jade processing is often used in the arc or curved surface, so it often uses soft jade polishing tools.
The simple jade polishing is to polish the surface of the semi -finished product of jade carving more delicate and flat, and polish with the special polishing powder. Generally use iron oxide powder, chromium oxide powder and natural diamond microfimpe. The polishing agent is adjusted with water and oil juice, applied to soft materials, and then slowly rubbed on the surface of the jade. After a period of time, you can see the surface of the smooth and clean jade. Then clean it, apply the paraffin to the roasted hot jade, wait for the cold, wipe the surface with a cloth, so that the surface of the jade has a crystal brightness.
