Abstract
The invention discloses a method for measuring the wear resistance of an ink layer of label paper. The method is characterized by comprising the following steps of: (1) measuring the color density of the ink layer to be worn by using a reflection densitometer, measuring three points, and taking an average value, wherein the three points and the measured three points after friction are in same positions; (2) shearing the ink layer to be worn into a sample and a stainless steel plate with certain sizes and then respectively fixing the sample and the stainless steel plate on a friction body and a friction platform; (3) starting a friction test machine for reciprocating friction, stopping the machine, and taking down the sample; and measuring the positions of three points by using the reflection densitometer and taking the average value. The method is closer to the actual condition of cigarette packet friction on a packaging machine, and the sample is fixed on the friction body, so that the implementation is easier. The method has the advantages that the process is simple, the cost is low, and the measurement on the wear resistance of the ink layer of the label paper can be simply, quickly and directly carried out.
Description
Technical field
The invention belongs to the cigarette package technical field of measurement and test, be specifically related to a kind of label paper China ink layer fastness to rubbing assay method.
Background technology
Label paper China ink layer wearing quality is meant the resistivity of label paper ink coating to the friction mechanism effect.In the tobacco bale package production; Because the needs of technological process; Need many places repeatedly to carry out contacting of ink lay and equipment,, will cause to scratch, grind colored even damaged phenomenon if the printing ink wearing quality of label paper itself is low; Cause pattern disappearance or tobacco bale surface that scratch is arranged, had a strong impact on the presentation quality of cigarette package.Along with the automatic package speed of cigarette enterprise increases substantially, to label paper China ink layer fastness to rubbing require increasingly high.
At present, the standard of label paper China ink layer wearing quality main reference is tested for the assay method of lithographic plate embellish and pressing article China ink layer wearing quality, the main China ink layer testing machine that adopt, and friction papers adopts 80g/m
2Cleaning offset paper (or A4 paper), test result compares value representation with the average density before and after the sample friction.This method is found to receive the influence of paper bigger in actual application, and standard deviation is also bigger, and it is qualified to occur the laboratory judgement easily, and the machine of going up defective phenomenon on probation.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this invention is to provide little, convenient and swift, the actual label paper China ink layer fastness to rubbing assay method of cigar mill of fitting more of a kind of error.
Above-mentioned purpose of the present invention is achieved through following technical scheme.
Invention provides label paper China ink layer fastness to rubbing assay method, adopts reflection densitometer to measure, and may further comprise the steps: sample wait the to rub an ink stone colour density of layer is measured in (1), surveys 3 positions, averages; (2) sample, corrosion resistant plate are separately fixed on the friction piece, rubbing table of frictional testing machine; (3) open frictional testing machine and come and go friction, shut down and take off the colour density that sample is measured 3 positions once more, average.3 positions that 3 positions being measured can select step (1) to measure.
Said sample aspect to be measured is long-pending should to be slightly larger than the area size that friction piece rubs, and sample adopts the mode of pasting to be fixed on the friction piece.
Adopt corrosion resistant plate to place on the rubbing table, can be so that friction be even, error is little, the actual conditions of pressing close to packaging machine, this is one of important breakthrough of the present invention.Corrosion resistant plate thickness is preferably 1.0～2.0mm, and width is 30～50mm, and length is 60～100mm.Corrosion resistant plate preferred surface mirror polish, roughness are 0.1～0.4 μ m.
The material of adoptable preferred corrosion resistant plate is 302 or 304 type corrosion resistant plates.Be more preferably 304 steel plates.
Corrosion resistant plate picks an amount of detersive with Wiping material and carries out wiping before test; And then it is dried with clean absorbent cotton; So repeatedly more than three times; Until the workplace of corrosion resistant plate till estimating cleaning, after the cleaning, the workplace of not handy hand or other objects contact corrosion resistant plate.The corrosion resistant plate detersive is the SILVER REAGENT that is suitable for such as acetone, normal hexane, ethanol, isopropyl alcohol or the above solvent of technical grade of noresidue preferably.As preferred version, can select ethanol.Wiping material can be preferably the soft fabric that absorbent gauze, absorbent cotton, nonwoven fabrics etc. do not have staple fibre to drop, and does not contain the material that dissolves in detersive.
Step (1) and (3) can adopt reflection densitometer to measure the colour density of sample.
The described round friction number of times of step (3) is 20 ~ 160 times.
The present invention on the prior art basis, has improved friction media owing to having adopted above technical scheme, adopts corrosion resistant plate to replace offset paper, and more near tobacco bale friction actual conditions on the packaging machine, and sample is fixed on the friction piece enforcement more easily.Technology of the present invention is simple, and is with low cost, need not to carry out scrap build, can directly carry out the mensuration of label paper China ink layer fastness to rubbing.
