Summary of the invention
The present invention seeks to provides a kind of method of measuring smoothness of glass paper at above-mentioned defective, and this method can be carried out accurate data to the slippery of viscose paper and be characterized.
In order to realize purpose of the present invention, the method for measuring smoothness of glass paper provided by the present invention comprises the steps:
(1) gets one section viscose paper to be measured,, get the level and smooth strip batten 6-10 bar of measure-alike limit portion at interval uniformly along the fabric width of viscose paper;
(2) the arbitrary batten in (1) is placed between two ganoid flat boards that pile up up and down together, one end of batten is exposed between two flat boards, clamp the bared end of batten with clip, under the situation that two flat boards can not slide relatively, with tautness meter hook clip batten from the uniform velocity parallel pulling out between two flat boards, the record batten pull out the full-scale reading on the tautness meter in the process; Then the residue batten is carried out above-mentioned identical operations respectively, write down each batten and pull out the full-scale reading on the tautness meter in the process;
(3) to the total data averaging that is write down in (2), the average of trying to achieve is used for representing the slippery of the viscose paper of surveying.
In the above-mentioned steps, described batten length is 150mm-300mm, and width is 30mm-60mm.
In the above-mentioned steps, described ganoid flat board is a glass plate.
Among the present invention, the Width of batten is consistent with the fabric width direction of viscose paper, the length direction of batten and the vertical consistency of viscose paper, when cutting batten, carry out uniformly at interval along the fabric width direction of viscose paper, it is level and smooth that the limit portion of the batten that cuts wants, promptly can not be jagged on the limit of batten.On the basis of the fabric width that has viscose paper now, consider the bar of taking a sample reply viscose paper integral body representative, consider the simplicity of measuring operation again, after repeatedly testing, we think that 6-10 bar batten just can satisfy the needs that smoothness of glass paper is measured, and the length of every batten is that 150mm-300mm, width are that 30mm-60mm is suitable.Certainly, the bar number of batten is many more, and the data of measuring are just definite more.For the selection of two ganoid flat boards, consider the difficulty or ease of processing, the smooth glass plate of our priority selection faces, the length and width size of two glass plates is preferably identical.The length of glass plate is shorter than the length of above-mentioned batten, clamps the position to reserve; The width of glass plate is wideer than the width of above-mentioned batten, is not exposed at outside the glass plate with the both sides that guarantee batten.Above the weight of a glass plate to satisfy such requirement: can guarantee has enough pressure to batten, unlikelyly again when pulling out, batten is broken, the weight of a following glass plate can with the varying in weight of a top glass plate.Pull out in the process in order to prevent batten, two glass plates take place to slide relatively, can be placed on two glass plates in the box of an open top, the inner chamber of box is corresponding with the size of glass plate, the end wall of box is provided with the breach of pulling out for batten, the sidewall of box is provided with the gap that makes things convenient for glass plate to take out and put into, and gets final product box is fixing during use.For the data that make acquisition accurately and reliably, the distance that all battens slide between two glass plates is identical.
In the actual detected, the length of used batten is 300mm, the wide 37mm of being, the length of glass plate is 220mm, the wide 120mm of being and heavily is about 350 grams.Determining the size of weight, size and the batten of glass plate, is for easy to operate purpose, does not represent the glass plate of other weight and size and the batten of other sizes can not realize goal of the invention.When measuring for the first time with the glass plate and the batten of which kind of specification, continue when detecting later on to use the glass plate of this specification and batten just can, the data repeatedly measured of front and back just have comparability like this.
When measuring the slippery of viscose paper, all be under the environmental baseline of uniform temperature and relative humidity, to carry out, for the data of repeatedly measuring before and after making have comparability, which kind of under temperature and relative humidity condition, carry out when measuring for the first time, get final product identical of temperature when so later measurement, the temperature during measurement are measured with the first time with the relative humidity condition with the relative humidity condition.Certainly, environment temperature during measurement and relative humidity preferably meet the requirement among standard GB/T10739-2002 " paper, cardboard and paper pulp sample are handled and the standard atmosphere condition of experiment ".
The present invention has following advantage:
1, measuring appliance is simple in structure, and material is easy to get, and makes easily;
2, easy and simple to handle;
3, can be with the slippery of definite numerical representation method viscose paper.
Embodiment
Embodiment 1
Take off one section from viscose paper to be measured, in its fabric width direction of one section viscose paper upper edge of taking off, get at interval long 8 of the wide strip battens for 37mm of 300mm that are uniformly, the limit portion of each batten can not be jagged.Get two ganoid glass plates that size is identical with weight, the length of every glass plate is 220mm, the wide 120mm of being and heavily is about 350 grams.Wherein one is placed in the tub, gets above arbitrary the glass plate that lies in the tub in 8 battens, with another piece glass plate batten is pushed down, an end that makes batten is to exposing outside 80mm.Pasting the bared end that glass plate is clamped batten with clip, with tautness meter hook clip batten from the uniform velocity parallel pulling out between two glass plates, parallel implication of pulling out is meant that batten is parallel with two glass plates in the process of pulling out, and the full-scale reading on the tautness meter in the process pulled out in record, and reading is 120; Then remaining seven battens are carried out respectively and above-mentioned article one batten identical operations, write down each batten and pull out the full-scale reading on the tautness meter in the process, reading is respectively 100,120, and 140,120,100,140 and 120.Eight data averagings to being write down then, the average of trying to achieve is 120, the desired value of the slippery of the viscose paper of surveying is 120.Measure the environment temperature of above-mentioned data and relative humidity and meet requirement among standard GB/T10739-2002 " paper, cardboard and paper pulp sample are handled and the standard atmosphere condition of experiment ".
As shown in drawings, the tub described in the embodiment comprises box body 1, and the open top of box body 1, the end wall of box body 1 are provided with the breach 2 of pulling out for batten, and the sidewall of box body 1 is provided with the gap 3 that makes things convenient for glass plate to pick and place.The height of the wall of box body 1 is the thickness sum of two glass plates, and the inner cavity size of box body 1 is corresponding with the glass plate size.Also show among the figure and be placed on the glass plate 4 in the box body 1 and be positioned at batten 5 between two glass plates.
