Problems solved by technology

[0004] During the peeling process of mica sheets, traditionally use peeling tools to peel them dry. Since the mica sheets are very thin, the mica sheets only need to be peeled to a thickness of about 0.02mm. Dry peeling is likely to produce red and green filaments (bubbles), resulting in serious scratches and affecting Normal use of mica flakes

Embodiment 1

[0021] The preparation method of the soaking solution is as follows: 1) Mix 50 parts of rice-washing water and 0.4 nano-titanium oxide, adjust the pH of the solution to 6.5, and ultrasonically disperse for 10 minutes;

[0022] 2) Add 2 parts of sodium chloride, 3 parts of glycerin, 4 parts of lemon essential oil, 2 parts of tourmaline powder, and 10 parts of polyvinyl alcohol, adjust the pH of the solution to be neutral, and mix and stir evenly.

[0023] 1) select mica sheet: the synthetic mica sheet is carried out sampling inspection, selects the qualified mica sheet as raw material for subsequent use;

[0024] 2) Pretreatment: put the mica sheet selected in step 1) into the soaking liquid and soak for 2 hours. Ultrasonic cooperation is used during soaking. The ultrasonic wave is used for 20 minutes. The formula of the soaking liquid is as follows: 50 parts of rice washing water, chlorine 2 parts of sodium chloride, 3 parts of glycerin, 4 parts of lemon essential oil, 2 parts...

Abstract

The invention discloses a mica sheet peeling method. The mica sheet peeling method specifically comprises the following steps that firstly, mica sheet selecting is conducted, synthesized mica sheets are subjected to spot check, and the mica sheets qualified through quality testing are selected as raw materials to be used later; secondly, pretreatment is conducted, the mica sheets selected in the first step are placed in immersing liquid to be immersed for 2-4 h, the ultrasonic cooperation manner is adopted during immersing, the ultrasonic usage time duration is 20-40 min, and the formula of the immersing liquid comprises 50-70 parts of rice washing water, 2-10 parts of sodium chloride, 3-8 parts of glycerinum, 4-8 parts of lemon essential oil, 2-6 parts of tourmaline powder, 10-16 parts ofpolyvinyl alcohol and 0.4-0.8 part of nano titanium oxide; and thirdly, wet peeling is conducted, the mica sheets obtained after ultrasonic immersing treatment are subjected to wet peeling, water isinjected into the mica sheets in a low-pressure flushing manner, the mica sheets are completely immersed in water, then, a sheet peeling tool is used for peeling, and then separated mica sheets are obtained. Operation is simple and convenient, scratches cannot be generated, and the performance of the mica sheets in various aspects is not influenced.

Description

technical field [0001] The invention relates to the field of mica sheet peeling, in particular to a mica sheet peeling method. Background technique [0002] Mica is a rock-forming mineral that presents a hexagonal flaky crystal shape and is one of the main rock-forming minerals. The mica crystal has a layered structure inside, so it is a flaky crystal, mainly hexagonal flaky crystals. Mica has very high insulation and heat insulation properties, good chemical stability, and has the ability to resist strong acid, strong alkali and pressure, so it is An important raw material for the manufacture of electrical equipment, it can also be used as insulation in hair dryers. Mica also has birefringence, so it is also an optical instrument material for making polarizers. [0003] Mica sheet is an insulating sheet. The thick mica is stripped, thickened, cut, drilled or punched. It has a certain thickness and a certain shape of the mica parts. This product is suitable for industrial ...
