Problems solved by technology

The cost of degumming and degumming is relatively high, mainly due to high power consumption, gas consumption (acetylene) and labor costs
Moreover, the daily processing output is small, and the possibility of increasing the production in the traditional way is small, and the possibility of degumming and degumming in large quantities cannot be realized.
In addition, in terms of degumming quality and subsequent washing treatment, there are also problems such as "missing inspection" and other defective products.
[0003] Disadvantages of the existing degumming method "high-temperature boiling": high power consumption and high cost. After degumming, external force must be used to remove surface viscose impurities, and such degumming process needs to be completed by a special person, generally 2-4 to complete, personnel Increased costs
[0004] Disadvantages of the existing degumming method "high temperature fire roasting": use acetylene or other gases to bake the glue repeatedly, so that the glue is carbonized at high temperature, and a large amount of smoke will be generated. Inhaling the smoke will cause great harm to personnel, and the price of heatable gases such as acetylene is relatively high. High, after degumming, scaling will form on the surface of the silicon material, and special personnel are required to complete the removal of the scaling, and this type of scaling will cause unqualified products in the later cleaning of the silicon material. According to the disadvantages of residual impurities, it usually takes 2 -Completed by 4 people, increased personnel cost
Less feasible to achieve mass production

Embodiment 1

[0016] The degumming and cleaning method of the whole sheet material includes the following steps: Step 1. First, simply arrange and classify the sheet materials that need to be degummed, remove the interlayer sheets, and try to ensure the integrity of the sheet materials to be processed;

[0017] Step 2, sorting the slices for degumming and soaking, and soaking the whole slice alone;

[0018] Step 3, the degumming process of the whole piece of flakes Add 300kg of flakes to 125kg of degumming cleaning agent, the raw materials of degumming and cleaning agent are as shown in Table 1, soak for 24 hours, seal the whole soaking process, wait for the degumming agent and glue to react, during There is no need for additional manual processing. Each degumming cleaning agent can process two rounds of flakes. After degumming, the flakes are directly cleaned and rinsed to complete the pretreatment process of the flakes;

[0019] Step 4. The semi-finished products after soaking, rinsing an...

Embodiment 2

[0022] The degumming and cleaning method of the whole sheet material includes the following steps: Step 1. First, simply arrange and classify the sheet materials that need to be degummed, remove the interlayer sheets, and try to ensure the integrity of the sheet materials to be processed;

[0023] Step 2, sorting the sheets for degumming and soaking, and soaking the whole sheet separately;

[0024] Step 3, add 300kg of the sheet material to 125kg of degumming cleaning agent during the degumming process of the whole sheet material, the raw materials of the degumming cleaning agent are as shown in Table 1, soak for 24 hours, seal the whole soaking process, and wait for the degumming agent to react with the glue. There is no need for additional manual processing during the period, each degumming cleaning agent can process two rounds of flakes, and the flakes after degumming are directly cleaned and rinsed to complete the pretreatment process of the flakes;

[0025] Step 4. The se...

Embodiment 3

[0034] The degumming and cleaning method of debris and flakes includes the following steps: Step 1. First, simply sort and classify the flakes that need to be degummed, remove the interlayer flakes, and try to ensure the integrity of the flakes to be processed;

[0035] Step 2, classify the slices for degumming and soaking, and divide them into whole slices and fragments for separate soaking;

[0036] Step 3: Add 135kg of the degumming cleaning agent added in Example 1 to 260kg of flakes during the degumming process and soak for 36 hours. The entire soaking process only needs to be sealed and wait for the degumming agent to react with the glue. No additional manual processing is required during the process. , Each degumming cleaning agent can process two rounds of flakes, and the flakes after degumming are directly cleaned and rinsed to complete the pretreatment process of the flakes;

[0037] Step 4. The semi-finished products after soaking, rinsing and cleaning of the chips ...

Abstract

The invention discloses a sheet degumming and cleaning method, comprising the following steps: simply arranging and classifying sheets required to be degummed; performing degumming soaking on the sheets in a classified manner; only requiring to seal in the whole soaking process; waiting for reaction between a degumming agent and glue; directly flowing a semi-finished product, obtained after the sheets are soaked, rinsed and cleaned, to the pickling step; performing the processes of pickling loss removal, alkali washing decontamination and pickling metal impurity removal; and completing the whole cleaning process of the sheets. The degumming cleaning agent contains the following raw materials in parts by weight: 1-99 parts of ethylene glycol, 1-99 parts of absolute ethyl alcohol, 1-99 parts of formic acid, 1-99 parts of dichloromethane, 1-99 parts of phenol, and 1-99 parts of sodium dodecyl benzene sulfonate. Mass treatment can be implemented by using the degumming agent for degumming, the advantages of low consumption, less manpower, no need of heating and external force and thorough degumming can be achieved, and therefore the purpose of greatly reducing the processing cost in the degumming process is achieved.

Description

technical field [0001] The invention relates to a cleaning method for sheet material degumming, in particular to the technical field of sheet material degumming. Background technique [0002] Thick slices have sticky stick glue and resin blocks on the surface, and methods such as "high-temperature boiling" and "high-temperature fire roasting" are generally used to remove such impurities. The cost of degumming and degumming is relatively high, mainly due to high power consumption, gas consumption (acetylene) and labor costs. Moreover, the daily processing output is small, and the possibility of increasing the output in the traditional way is small, and the possibility of degumming and degumming in large quantities cannot be realized. And in terms of degumming quality and subsequent washing treatment, there are also problems such as "missing inspection" and other defective products.
