Abstract

The invention provides a pearl punching method. Pearl particles are taken, pearls are frozen in a refrigeration storage at the temperature of 50-80 DEG C below zero for 10-20 days, and harness of nacres is improved. After being taken out, the pearl particles are naturally cooled to a room temperature, and then are placed into sodium chloride solutions with the concentration of 25-56% and heated and immersed for 10-25 minutes. The pearls are placed on a leather rotary plate after being washed by clean water, and the polishing effect is achieved by constant contact of products in high-speed rotation and the leather surface of the rotary plate. Then, the pearls are washed clean with an ultrasonic cleaner. The pearls are placed in a mixture of glutamic acid, trigonal ionized acid, trigonal ionized alcohol, ethanol, resin and water after being drilled, then the pearls are put into a centrifugal machine for centrifugal processing, pores of the pearls are immersed by the solutions, and then the pearls are washed. By means of the method, the nacres of the pearls are seldom damaged, cracks of the pearls are reduced, and a decoration function is better achieved. The solutions which are prepared can immerse the pores of the pearls to form protection layers.

Description

The drilling method of a kind of pearl

Technical field

The invention belongs to material processing field, particularly the drilling method of a kind of pearl.

Background technology

Pearl is the material produced in pearl shell, its out-of-shape and color and luster is beautiful, people are usually used for making being connected or pasting and use as decoration on handicraft, but when still wearing into connected, need to punch on pearl, easily damage the nacre of pearl surface.

Summary of the invention

The object of this invention is to provide the drilling method of a kind of pearl, the nacre of the destruction pearl that this method can be little and reduce the crack of pearl, better play decoration function.

A drilling method for pearl, for completing according to following steps:

Get pearl particles, be chilled in by pearl in the freezer of subzero 50-80 degree Celsius, 10-20 days, strengthens nacreous hardness.

Naturally place room temperature after taking out, the sodium chloride solution putting into concentration 25-56% adds heat soaking 10-25 minute.

After taking out, clear water is rinsed well.

Then pearl is placed on cortex rotating disk, reaches polishing effect by the product in High Rotation Speed with continuous contact of rotating disk cortical face.Then use ultrasonic cleaner cleaning to clean.

Then drilling machine is used to hole; after boring; pearl is placed on glutamic acid 30-50%, three square cards for learning characters from sour 20-40%, three square cards for learning characters from the mixture of alcohol 30-50%, ethanol 12-39%, resin 14-21% and water 25-41%; then centrifuge process is put into; make solution immerse the gap, hole of pearl, form protective layer.

Then clear water rinses.

Necklace can be pierced.

Its advantage is:

This method can be little destruction pearl nacre and reduce the crack of pearl, better play decoration function.The solution configured can make solution immerse the gap, hole of pearl, forms protective layer.Better beautify everybody daily life.
