Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Sandpaper is a common abrasive article. In the polishing process of the existing abrasive paper, the polished fragments can block gaps among sand grains of the abrasive paper, so that the polishing effect is reduced. Therefore, the size of the gaps between the sand grains of the sandpaper has a certain influence on the sanding effect of the sandpaper. Gaps among the sand grains can not be too large or too small, the total number of the sand grains is reduced due to the too large gaps, effective polishing is difficult to carry out, and the fragments are easy to block due to the too small gaps, so that the polishing effect is reduced. The existing sand paper is difficult to accurately adjust the clearance between sand grains.
In view of this, referring to fig. 1 to 4, the present application discloses a sandpaper processing method, comprising the steps of:
s101: uniformly mixing the sand grains 130 with the first mesh size and the sand grains 150 with the second mesh size to form a mixture, and introducing the mixture into a processing panel; wherein the first mesh number is larger than the second mesh number. In the step, two sand grains with different mesh sizes are mixed. That is, two kinds of sand grains with different diameters are uniformly mixed. The mixed mixture is guided into a processing panel. At this time, the sand grains are spread flat by a single layer, and the sand grains are spread densely. Thus, the sand grains with large meshes occupy the gaps between the adjacent sand grains with small meshes, and similarly, the sand grains with small meshes occupy the gaps between the sand grains with large meshes.
S102: and an adsorption film is arranged above the processing panel, and static electricity is conducted on the adsorption film so as to adsorb the mixture on the processing panel. In the step, the adsorption film is firstly arranged above the processing panel and is arranged at an interval with the processing panel, and then static electricity is conducted on the adsorption film, so that sand grains on the processing panel are adsorbed to the adsorption film. To enhance the adsorption effect, the adsorption film may be brought into contact with the upper surface of the sand grains and then moved upward to detach the sand grains from the processing panel. All sand grains are in a state of being lifted by the adsorption film at this time.
S103: the amount of static electricity on the adsorption film is reduced to drop the second mesh size of sand particles 150. In this step, static electricity on the adsorption film can be led out in a stepwise manner, so that the static electricity on the adsorption film can just adsorb the sand grains 130 with the first mesh size and the sand grains 150 with the second mesh size, which have relatively light weight, fall off due to gravity. In this step, the adsorption film may be driven to vibrate in an auxiliary manner so as to facilitate the dropping of the sand grains, and the frequency and amplitude of the vibration are determined depending on the size and the number of the two kinds of sand grains. The ultimate goal is to just retain the first mesh size sand 130 and shake off the second mesh size sand 150.
S104: the first mesh size sand particles 130 on the absorbent film are adhered to the base paper 110. In this step, an adhesive layer is disposed on the base paper 110, and then the base paper 110 is disposed under the adsorption film to separate the sand particles on the adsorption film.
The application provides a sand paper processing method, first the sand paper homogeneous mixing of two mesh sizes, then absorb the mixture of the two through static, sand grain 130 of first mesh size is heavier, so after static reduces, sand grain 130 of first mesh size descends, only leaves sand grain 150 of second mesh size. In the scheme, the sand grains 130 with the first mesh size are uniformly doped among the sand grains with the second mesh size, namely, the gaps among the sand grains 150 with the second mesh size are adjusted through the sand grains 130 with the first mesh size. And the grit 130 of the first mesh size is selected to be of the appropriate size according to the desired clearance. This operation allows the gaps between the sand grains on the coated abrasive to be precisely adjusted as desired.
In the above steps, it should be particularly noted that the mixed sand grains introduced into the processing surface plate have a single-layered densely-paved structure. Namely, the sand grains are not overlapped in the vertical height, and the two adjacent sand grains are tightly attached in the horizontal plane. In order to achieve the above object, on the one hand, the upper surface of the processing panel may be provided with a concave spherical curved surface, and the height of the concavity is extremely small, so that, on the one hand, the sand grains are drawn toward the center of the lowest vertical height by gravity to achieve close arrangement therebetween, and overlap is not formed due to the small size of the concavity. Similarly, in the step of adsorbing the sand particles on the processing panel on the adsorption film, an attaching piece with a lower convex surface can be arranged above the adsorption film, and the adsorption film is attached to the lower surface of the attaching piece, so that the adsorption film can also form a spherical curved surface and can be further attached to the processing panel in shape, and the sand particles on the processing panel can be conveniently adsorbed.
In a preferred embodiment, the attaching member in the above embodiment includes an attaching panel attached to the adsorption film, the upper surface of the attaching panel is provided with a plurality of vertically arranged vibrating pieces, the vibrating pieces are arranged at intervals, auxiliary vibration of the attaching member can be realized by introducing high-speed airflow between the vibrating pieces, the auxiliary vibration is transmitted to the adsorption film, and sand with heavier weight can be vibrated.
In the above method, theoretically, the minimum value of the gaps between the remaining first mesh-sized sand grains 130 is the single diameter of the second mesh-sized sand grains 150, and the maximum value is infinite. For example, when the distance between two adjacent first-mesh-sized sand grains 130 is required to be equal to the diameter of four second-mesh-sized sand grains 150, sixteen parts of the second-mesh-sized sand grains 150 may be uniformly mixed with one part of the first-mesh-sized sand grains 130. The adjustment of the spacing between the sand grains on the sand paper can be indirectly realized by adjusting the number of the two kinds of sand grains with different meshes in the sand grain mixture.
According to some embodiments, after the step of reducing the amount of static electricity on the adsorption film to drop the second mesh size of sand particles 150, the method further comprises:
an adhesive is provided on the base paper 110, and an adsorption film is laminated on the adhesive-provided surface of the base paper 110 so that the sand grains 130 having the first mesh size adhere to the base paper 110.
According to some embodiments, after the step of adhering the first mesh size of sand grains 130 on the adsorption film to the base paper 110, the method further comprises:
an antistatic coating is applied to the surface of the base paper 110 to which the first mesh size sand grains 130 are bonded.
The present inventors have also found that in the practical application of sandpaper, it is now necessary to grind an article roughly and then finely. That is, different sizes of sandpaper are required to polish the same part. In the prior art, two kinds of sand paper with different meshes are used respectively.
According to some embodiments, after the step of coating the antistatic coating on the surface of the base paper 110 to which the first mesh size sand grains 130 are adhered, the method further comprises:
the second mesh size of sand particles 150 is adhered to the surface of the base paper 110 provided with the antistatic coating.
According to some embodiments, after the step of adhering the second mesh size of sand particles 150 to the surface of the base paper 110 provided with the antistatic coating, the method further comprises:
and coating the antistatic coating on the surface of the base material layer with the second mesh size again.
The sand paper processed by the processing method has the sand grains 150 with the second mesh size and the sand grains 130 with the first mesh size. Also, the second mesh size sand particles 150 cover the first comb size sand particles and are easily dropped during the sanding process. That is to say, the abrasive paper of this scheme design of adoption can be polished at the in-process limit of corase grind, and the sand grain that the mesh is big drops, and abrasive paper can continue to carry out the correct grinding again after dropping. I.e. one piece of sandpaper completes both the finish grinding and the rough grinding. The above-described grinding process of course requires that the ground parts be finished, i.e. that certain specific parts be finished and ground in one operation by means of the sandpaper produced by the method.
According to some embodiments, the first mesh value is greater than or equal to 800, and the second mesh value is less than or equal to 600.
According to some embodiments, after the step of coating the antistatic coating on the surface of the base paper 110 to which the first mesh size sand grains 130 are adhered, the method further comprises:
adhering the sand grains with the third mesh size to the surface of the base paper 110 provided with the anti-static coating; wherein the third mesh number is smaller than the first mesh number. That is, the coated abrasive includes both the first mesh size sand grains 130 and the third mesh size sand grains.
According to some embodiments, the first number has a value of 1000 or more and the second number has a value of 1000 or less.
One specific example of a method for processing sandpaper includes:
s201: uniformly mixing the sand grains 130 with the first mesh size and the sand grains 150 with the second mesh size to form a mixture, and introducing the mixture into a processing panel; wherein the first mesh number is larger than the second mesh number. In this step, two sand grains with different mesh sizes are mixed. That is, two kinds of sand grains with different diameters are uniformly mixed. The mixed mixture is guided into a processing panel. At this time, the sand grains are spread flat by a single layer, and the sand grains are spread densely. Thus, the sand grains with larger meshes occupy the gaps between the adjacent sand grains with smaller meshes, and similarly, the sand grains with smaller meshes occupy the gaps between the sand grains with larger meshes. The upper surface of the processing panel is set to be a concave spherical curved surface, and the concave height is extremely small, so that on one hand, sand grains can be close to the center with the lowest vertical height due to gravity, thereby realizing the tight arrangement of the sand grains, and the concave size is smaller, so that the overlapping can not be formed.
S202: and arranging an adsorption film above the processing panel, and conducting static electricity to the adsorption film so as to adsorb the mixture on the processing panel. In the step, the adsorption film is firstly arranged above the processing panel and is arranged at an interval with the processing panel, and then static electricity is conducted on the adsorption film, so that sand grains on the processing panel are adsorbed to the adsorption film. To enhance the adsorption effect, the adsorption film may be brought into contact with the upper surface of the sand grains and then moved upward to detach the sand grains from the processing panel. All the sand grains are suspended by the adsorption film. And in order to make the adsorption film can with be the equidistant setting of the processing panel of cambered surface, will adsorb the lower surface that the membrane laminating in the laminating piece for the adsorption film is spherical arc.
S203: the amount of static electricity on the adsorption film is reduced to drop the sand particles 150 of the second mesh size. In this step, static electricity on the adsorption film can be led out in a stepwise manner, so that the static electricity on the adsorption film can just adsorb the sand grains 130 with the first mesh size and the sand grains 150 with the second mesh size, which have relatively light weight, fall off due to gravity. In this step, the adsorption film may be driven to vibrate in an auxiliary manner so as to facilitate the dropping of the sand grains, and the frequency and amplitude of the vibration are determined depending on the size and the number of the two kinds of sand grains. The ultimate goal is to just retain the first mesh size sand 130 and shake off the second mesh size sand 150. Specifically, the high-speed gas is guided to the attaching piece, and the vibrating piece on the attaching piece vibrates to drive the adsorption film to vibrate.
S204: the first mesh size sand particles 130 on the absorbent film are adhered to the base paper 110. In this step, an adhesive layer is disposed on the base paper 110, and then the base paper 110 is disposed under the adsorption film to separate the sand particles on the adsorption film.
