Abstract
The invention discloses a kind of pan paper, the surface resistivity on its at least one surface is not more than 1010Ω, quantification of 25 45g/m of paper2, and the confficient of static friction on surface for weighing is not more than 0.25.By increasing antistatic composition, can further reduce surface resistivity, the decline of surface resistivity can effectively reduce " flying powder " phenomenon occurred when weighing nano-powder.Control surface roughness and the confficient of static friction of pan paper simultaneously, nano-powder class material can be made to shift from pan paper surface smoothly.
Description
Technical field
The present invention relates to a kind of pan paper, a kind of pan paper with antistatic property.
Background technology
Pan paper is often used in scientific experiments, and it as weighing carrier, can will be weighed after weighing easily in addition
Material shifts, more common in the weighing of solid powder substance.But, there is a defect in conventional pan paper, it is simply that electrostatic is very
Greatly, when weighing on the precision balance from static electrification alarm device, often prompting pan paper institute static electrification is excessive.Depositing of electrostatic
Influencing whether the weighing accuracy of balance, a small amount of material that is weighed also can be made when transfer of material to remain on pan paper, from
And cause the deviation of quality.When weighing some the lightest material such as nano-powders, these materials can because of the existence of electrostatic quilt
It is drawn onto the position such as edge of pan paper, occurs flying powder phenomenon, thus bring unnecessary trouble to weighing.Thus, manufacture is provided
The pan paper having certain antistatic property has the biggest realistic meaning.
Summary of the invention
The invention aims to provide a kind of pan paper, a kind of pan paper with antistatic property.
It is an object of the invention to be achieved through the following technical solutions:
A kind of pan paper, it is characterised in that the surface resistivity at least one surface is not more than 1010Ω, the quantification of 25-45 of paper
g/m2, and the confficient of static friction on surface for weighing is not more than 0.25.
The surface resistivity at least one surface of described pan paper is not more than 109Ω。
Further, the surface resistivity at least one surface of described pan paper is not more than 108Ω。
Further, the surface resistivity at least one surface of described pan paper is not more than 107Ω.Surface resistivity is passed through
The modes such as antistatic additive kind, consumption are adjusted.
The confficient of static friction on the described pan paper surface for weighing is not more than 0.2.
Further, the confficient of static friction on the described pan paper surface for weighing is not more than 0.15.
The roughness on the described pan paper surface for weighing is not more than 2 microns.
Further, the roughness on the described pan paper surface for weighing is not more than 1 micron.
The grease proofing grade on the described pan paper surface for weighing is not less than 2.
Further, the grease proofing grade on the described pan paper surface for weighing is not less than 4.
The pan paper that this patent is provided has antistatic property, will not adsorb and be weighed material, can avoid weighing nano-powder
Time occur fly powder phenomenon, be weighed thing and also will not remain on pan paper, can reduce weighing error, particularly alleged quality
Time less, effect becomes apparent from.Additionally, the pan paper that this patent is provided, the confficient of static friction weighing surface is little, it is simple to claimed
The transfer of amount thing, and waterproof oil-proof result is preferable.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in those skilled in the art and enter
One step understands the present invention, but limits the present invention the most in any form.It should be pointed out that, those of ordinary skill in the art is come
Say, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement.These broadly fall into the protection of the present invention
Scope.
Embodiment 1
In the present embodiment, wood pulp adds antistatic additive, after making beating through handsheet, squeeze, dry, weigh face applying glue, applying glue
Amount is 1g/m2, after drying, become paper, the quantification of 40g/m of paper2.It is 0.25 that gained pan paper weighs the confficient of static friction in face,
The surface resistivity at the back side is 6 × 109Ω。
By improving the content of antistatic additive, surface resistivity can be made to continue to decline, thus realize 108Ω rank and resistance are more
Add the little order of magnitude.
Embodiment 2
In the present embodiment, wood pulp adds antistatic additive, film forming matter, coalescents, after making beating through handsheet, squeeze, dry
Paper, the quantification of 25g/m of paper is become after Gan2.It is 0.2 that gained pan paper weighs the confficient of static friction in face, the sheet resistance of positive and negative
