Abstract
The invention discloses a piece of weighing paper. The surface resistivity of at least one surface of the weighing paper is not greater than 1010 ohms, the quantity of the paper is 25-45 g/m<2>, and the static friction coefficient of the surface for weighing is not greater than 0.25. The surface resistivity can be further reduced by increasing antistatic components, and due to reduction of the surface resistivity, the possibility of powder flying can be effectively reduced when nano-powder is weighed. Meanwhile, substances like nano-powder can be transferred from the surfaces of the weighing paper smoothly by controlling the surface roughness and the static friction coefficient of the weighing paper.
Description
Technical field
The present invention relates to a kind of pan paper, particularly a kind of pan paper with antistatic property.
Background technology
Pan paper is often used in scientific experiment, and it, in addition as weighing carrier, can will be weighed substance transfer easily, being comparatively usually used in the weighing of solid powder substance after weighing.But conventional pan paper exists a defect, be exactly that electrostatic is very large, when the precision balance from static electrification warning device weighs, pan paper institute static electrification often can be pointed out excessive.The existence of electrostatic can have influence on the weighing accuracy of balance, a small amount of material that is weighed also can be made to remain on pan paper, thus cause the deviation of quality when transfer of material.When weighing some very light materials as nano-powder, these materials can be drawn onto the positions such as the edge of pan paper because of the existence of electrostatic, occur flying powder phenomenon, thus bring unnecessary trouble to weighing.Thus, produce the pan paper with certain antistatic property and there is very large realistic meaning.
Summary of the invention
The object of the invention is to provide a kind of pan paper, particularly a kind of pan paper with antistatic property.
The object of the invention is to be achieved through the following technical solutions:
A kind of pan paper, is characterized in that the surface resistivity at least one surface is not more than 10
10Ω, the quantitative of paper is 25-45g/m
2, and be not more than 0.25 for the coefficient of static friction on the surface weighed.
The surface resistivity at least one surface of described pan paper is not more than 10
9Ω.
Further, the surface resistivity at least one surface of described pan paper is not more than 10
8Ω.
Further, the surface resistivity at least one surface of described pan paper is not more than 10
7Ω.Surface resistivity is regulated by modes such as antistatic agent kind, consumptions.
Described pan paper is not more than 0.2 for the coefficient of static friction on the surface weighed.
Further, described pan paper is not more than 0.15 for the coefficient of static friction on the surface weighed.
Described pan paper is not more than 2 microns for the roughness on the surface weighed.
Further, described pan paper is not more than 1 micron for the roughness on the surface weighed.
Described pan paper is not less than 2 for the grease proofing grade on the surface weighed.
Further, described pan paper is not less than 4 for the grease proofing grade on the surface weighed.
The pan paper that this patent provides has antistatic property, can not adsorb and be weighed material, can avoid weigh nano-powder time occur fly powder phenomenon, be weighed thing and also can not remain on pan paper, can reduce weighing error, when particularly alleged quality is less, effect is more obvious.In addition, the pan paper that this patent provides, the coefficient of static friction weighing surface is little, be convenient to the transfer being weighed thing, and waterproof oil-proof result is better.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
