Abstract

The invention discloses a wall painting nail-lifting and falling pigment layer residue block pasting auxiliary device and a method, the falling pigment layer residue block pasting auxiliary device and the matched use method of the invention are that a transparent carrier is close to a falling position corresponding to the falling pigment layer residue block on a wall painting by using the auxiliary device, whether the edge of the falling pigment layer residue block is aligned with the edge of the falling position is observed from the opening end of a presser, the angle position of the auxiliary device is adjusted until the edge of the falling pigment layer residue is aligned with the edge of the falling position, or the picture on the falling pigment layer residue corresponds to the falling position of the mural, the whole process is visual, and compared with the traditional mode, the transparent carrier is pushed by the pressing device to press the falling pigment layer residue back to the falling position, so that the residue is more easily and accurately pasted.

3. The method for returning and attaching the residual pigment layer on the wall painting nail-lifting and falling pigment layer according to claim 2, wherein the transparent carrier is glass or acrylic plate, the outer side wall of the transparent carrier is matched with and contacted with the side wall of the stepped hole groove, the transparent carrier is slidingly connected to the inner wall of the stepped hole groove, and in the fourth step, the transparent carrier moves along the direction parallel to the wall painting when the auxiliary device is moved.
4. The method for pasting back the wall painting nail-lifting and falling pigment layer residue according to claim 2, wherein the transparent carrier is transparent parchment paper and transparent cellophane, the annular magnet is arranged in the stepped hole groove, the loading shell is made of iron, the transparent carrier is limited in the stepped hole groove through the annular magnet, in the step three, when the presser pushes the transparent carrier, the pigment layer residue which falls off together with the middle part of the transparent carrier is close to the wall painting, the edge of the transparent carrier is pulled out from a gap between the annular magnet and the bottom wall of the stepped hole groove, the transparent carrier is separated from the loading shell, and after the auxiliary device is removed, the transparent carrier moves in a direction parallel to the wall painting and is separated from the falling pigment layer residue.

Description

Auxiliary device and method for sticking residual blocks of fresco nail-lifting and falling pigment layer back Background In the wall painting protection work, the mogao hole wall painting is mostly made of mineral pigment due to different wall painting manufacturing processes, and the mineral pigment is added with glue in the drawing process. The traditional repairing method is to reinforce and repair the part of the wall painting, which is the premise of the subsequent repair of the residual block, and then to use an iron or wooden repair knife to combine with the injection of the repairing agent for the repair, and the residual block is stuck on the repair knife, so that the picture and the edge on the residual block cannot be seen during operation, the whole process is carried out by experience, the misplacement is easily caused after the repair, and the repairing process is difficult. Disclosure of Invention (1) Aiming at the problems that the residual blocks of the fallen pigment layer are easy to misplace and difficult to repair after being pasted back in the traditional mode, the invention provides an auxiliary device and a method for pasting back the residual blocks of the fallen pigment layer of the mural painting. (2) The technical scheme adopted by the invention is as follows: The utility model provides a mural painting plays first pigment layer residual block back and pastes auxiliary device that drops, is including being cylindric and loads the shell, loads the shell tip and is provided with the shoulder hole groove, sets up transparent carrier on the shoulder hole inslot diapire, loads the inside cylindric presser that is provided with of shell, the external diameter of presser matches with loading the shell internal diameter, and the flexible swing joint of presser is in loading the shell, the presser is located the fixed transparent dish that is provided with of one end that loads the shell. A method for sticking back the residual blocks of the pigment layer of the fresco nail-lifting and falling off comprises the following specific steps: firstly, cleaning dust on the front side and fine dust on the back side of a nail-lifting part of the pigment layer by sequentially using an ear-washing ball and a soft wool pen, then injecting prepared adhesive into the back side of the nail-lifting part of the pigment layer by using an injector (if necessary, slightly wetting with distilled water), pressing back the nail-lifting part by using a wooden repair knife filled with tissue paper after the moisture of the adhesive material is absorbed by a ground layer, and finally lightly rolling a cotton ball made of cotton wrapping absorbent cotton from the non-split part of the pigment layer to remove air which is not discharged locally at the nail-lifting back-pasting part; Secondly, cleaning the back of the residual block of the fallen pigment layer by using an ear ball and a soft brush, then placing the residual block of the fallen pigment layer on the surface of a transparent carrier, injecting distilled water into the pigment layer part by using an injector to combine the pigment layer with the transparent carrier, wherein the main purpose is that the distilled water can soften the pigment layer, the transparent sulfuric acid paper can see the picture of the wall painting, and the pigment layer cannot fall and move at an angle of ninety degrees or more during the back pasting. Step three, holding the auxiliary device to enable the transparent carrier to be close to the falling position corresponding to the falling pigment layer residue on the mural painting, observing whether the edge of the falling pigment layer residue is matched with the angle and the picture of the falling position from the opening end of the presser, adjusting the angle position of the auxiliary device until the edge of the falling pigment layer residue is matched with the angle and the picture of the falling position (checking according to the falling position of the pigment layer, aligning the angle to be matched with the original mural painting), and pressing the presser to push the transparent carrier to press the falling pigment layer residue back to the falling position; step four, moving an auxiliary device to separate the residual block of the dropped pigment layer from the transparent carrier; And fifthly, injecting a mural painting binder by using a repair nail-lifting method to strengthen the residual block part of the pigment layer.
