Abstract
The invention relates to a method for measuring the porosity of a sizing material by utilizing a scanner. The method comprises the following steps: firstly, measuring the weight of a tyre crown by using a calibrated electric platform scale, and recording, measuring the length of the tyre crown by using a tape, and recording; secondly, measuring and then transversely cutting out a tyre crown with the length of 100-200mm from the middle of the tyre crown by using a blade; thirdly, putting the cut-out tyre crown into the scanner and scanning cross section, to obtain the cross section area of the to-be-measured tyre crown; fourthly obtaining the porosity according to a weight calculation method, wherein the calculation formula of the weight calculation method is as follows: porosity equal to (theoretical weight subtracting practical weight)/theoretical weight, wherein the theoretical weight is equal to practically measured cross section area*tyre crown length*sizing material density. The porosity of the sizing material is measured by utilizing an offline/online scanner, the measured data is high in reliability, the data research value is higher, the measurement method is simple, practical and convenient, fewer in artificial interference factors, good in application prospects, and is a pioneer of company industry.
Description
Technical field
The invention belongs to the technical field of quality testing, relate in particular to a kind of method of measuring the porosity.
Background technology
Existing market reflection company product is not wear-resisting, and client's complaint is larger.By the careful investigation to production technology, think and cause not wear-resisting main cause to have three aspects:
sizing compound formula is unreasonable;
extrude the tyre surface porosity larger;
the fluctuation of conditions of vulcanization temperature and pressure is large.
The measuring method of traditional porosity is " drainage ".The parts of preparing to measure are put into tank, utilize the volume of the water that arranges to calculate theoretical weight: volume (the V) × sizing material density (ρ) of the water of theoretical weight=arrange
Measuring process is loaded down with trivial details, and the accuracy of data is not high, is often subject to manual operation impact, and error is larger, and the value of data is not high.
By part tyre surface has been carried out to Measure and test, my the tyre surface porosity of company's part specification is higher in the recent period, has reached the control criterion of the current industry of 6%-7%(inside below 3%), this also more confirms that the wearing quality of tyre surface and the porosity have stronger relevance.
Summary of the invention
Technical matters to be solved by this invention is to improve the degree of accuracy of measuring the porosity, makes the researching value of data higher, thereby a kind of method of utilizing scanner to measure the sizing material porosity is provided.
In order to address the above problem by the following technical solutions: a kind of method of utilizing scanner to measure the sizing material porosity, comprise the following steps: the first step, use weight the record of the electronic platform scale measurement crown after calibration, use length the record of tape measure crown; Second step, measures the rear blade of using and takes out the crown of 100～200 mm length from crown middle part transverse cutting; The 3rd step, puts into scanner by crown after intercepting and carries out cross dimensions scanning, obtains the cross sectional area of crown to be measured; The 4th step, then obtain the porosity according to " weighing scale algorithm ", the computing formula of described " weighing scale algorithm " is as follows: the porosity=(theoretical weight-actual weight)/theoretical weight, wherein, theoretical weight=measured profile area × crown length × sizing material density.
In second step, xsect is vertical as far as possible.
In second step, the degree of tilt of xsect is at least greater than 75 degree.
The present invention utilizes from/online scanner and measures the sizing material porosity, and the data reliability recording is high, and the researching value of data is higher, and measuring method is simple and practical convenient, and artificial interference factor is few, and application prospect is good, for my company's industry pioneering.
Embodiment
Utilize scanner to measure a method for the sizing material porosity, comprise the following steps: the first step, the electronic platform scale of use after calibration measured weight the record of crown, uses length the record of volume dimensional measurement crown; Second step, measure the rear blade of using and take out the crown of 100～200 mm length from crown middle part transverse cutting, xsect is vertical as far as possible, and degree of tilt is at least greater than 75 degree, and the crown after sampling marks weight, length, specification, decorative pattern code name and the production information of measurement with silver powder pen; The 3rd step, puts into scanner by crown after intercepting and carries out cross dimensions scanning, obtains the cross sectional area of crown to be measured; The 4th step, then obtain the porosity according to " weighing scale algorithm ", the computing formula of described " weighing scale algorithm " is as follows: the porosity=(theoretical weight-actual weight)/theoretical weight, wherein, theoretical weight=measured profile area × crown length × sizing material density.
Utilize from/online accurately the cross-sectional area of measurement component of scanner, according to mathematical formulae: theoretical weight=measured profile area (S) × crown length (L) × sizing material density (ρ), can calculate the theoretical weight of piece volumes and parts accurately; Use electronic platform scale to measure parts actual weight.
