Embodiment 1
[0032] The glue remover is prepared by mixing the components according to the following formula:
[0039] Test the gel removal effect of the gel remover in Examples 1 to 3 according to the following test method:
[0040] Use a dropper to drop a drop of glue removal agent on the glue on the back of the microdermabrasion. Poke it back and forth with a glass rod until the glue separates from the microdermabrasion. Record the time from dropping the glue removal agent to the separation of the glue. it is good. After testing, the glue removal time of the glue remover in Example 1 is 10-15s; the glue removal time of the glue remover in Example 2 is 25-30s; the glue removal time of the glue remover in Example 3 is 35-40s .

Abstract
The invention provides a buffing and gum-removing agent. The buffing and gum-removing agent is prepared from the following components in percent by mass: 15-50% of gum-removing solvent, 5-40% of auxiliary solvent and 20-50% of solubilizing agent, wherein the gum-removing solvent comprises one or several of dipropylene glycol dimethyl ether, dipropylene glycol monomethyl ether, diethylene glycol dimethyl ether, diethylene glycol monomethyl ether and diacetone alcohol; and the auxiliary solvent comprises one or several of propylene glycol phenyl ether acetate, aceticacidphenoxyethylester, diethylene glycol monoethyl ether acetate and propylene glycol methyl ether acetate. The buffing and gum-removing agent provided by the invention can act with residual buffing gum quickly, so that the residual buffing gum can be quickly separated from a disc surface of a machine platform. The buffing and gum-removing agent is simple in preparation process, stable in property and excellent in effect. Allthe residual buffing gum can be removed by only 10-40 s. The flashing point of the buffing and gum-removing agent is 55 DEG C or above, so that the buffing and gum-removing agent is safe and is not prone to fire blast. The components used by the buffing and gum-removing agent do not contain benzene, chloride, heavy metal and the like, so that the buffing and gum-removing agent is relatively low in odor and is green and environmentally friendly.
Description
Technical field [0001] The invention belongs to the field of glue removers, and in particular relates to a degelling agent for grinding skin. Background technique [0002] Sapphire is a general term used for aluminum oxide (Al2O3) single crystal materials. Sapphire is used for windows for infrared and microwave systems, optical transmission windows for ultraviolet to near-infrared light, light-emitting diodes, ruby lasers, laser diodes, for microelectronic integrated circuit applications and the growth of superconducting compounds and gallium nitride Supporting materials, and the like are particularly useful materials. Sapphire has excellent chemical stability, optical transparency, and desirable mechanical properties such as chipping resistance, durability, scratch resistance, radiation resistance, good matching to the thermal expansion coefficient of gallium arsenide, and resistance to high temperatures. Bending strength. [0003] Sapphire polishing is the last process of sa...
