Embodiment Construction

[0011] A method utilizing a scanner to measure the porosity of rubber materials, comprising the following steps: the first step, using a calibrated electronic platform scale to measure and record the weight of the tire crown, and using the roll size to measure and record the length of the tire crown; the second step After the measurement, use a blade to cut out a crown with a length of 100-200 mm from the middle of the crown. The cross-section is as vertical as possible, and the inclination is at least greater than 75 degrees. The weight and length of the crown after sampling are marked with silver chalk. , specifications, pattern code and production information; the third step is to put the intercepted crown into the scanner to scan the cross-sectional size to obtain the cross-sectional area of ​​the crown to be tested; the fourth step is to get Porosity, the calculation formula of the "weight calculation method" is as follows: porosity = (theoretical weight - actual weight) / ...

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 [0001] The invention belongs to the technical field of quality inspection, and in particular relates to a method for measuring porosity. Background technique [0002] At present, the market reflects that the company's products are not wear-resistant, and customers complain a lot. Through careful investigation of the production process, it is believed that there are three main reasons for non-wear resistance: The formula of the rubber material is unreasonable; The porosity of the extruded tread is relatively large; Vulcanization conditions fluctuate greatly in temperature and pressure. [0003] The traditional measurement method of porosity is "drainage method". Put the parts to be measured into the water tank, and use the volume of the displaced water to calculate the theoretical weight: Theoretical weight = the volume of the displaced water (V) × the density of the rubber compound (ρ) [0004] The measurement steps are cumbersome, and the accuracy of...
