Problems solved by technology

[0002] There is currently no technical solution for determining the degree of vulcanization of the inner tube. The existing solutions mainly rely on subjective evaluation or rough evaluation of the physical properties of the finished product. The disadvantages of the existing technical solutions are: the position of the carcass

Abstract

The invention discloses a method for measuring the vulcanization degree of an inner tube, which comprises the following steps of: 1, arranging a plurality of temperature measuring points in an inner tube mold, and measuring the multi-point vulcanization temperature of the inner tube mold; and 2, calculating the vulcanization degree according to the following calculation formula: lnK = lnA-Ea/RT (the Arrhenius formula), wherein K is the rate constant, calculation is carried out according to T90, A refers to the pre-factor, Ea refers to vulcanization reaction activation energy, R refers to the mole gas constant, and T refers to the thermodynamic temperature. Through a temperature measuring method in the vulcanization degree of the inner tube provided by the scheme, the real-time temperature of each part of the inner tube can be accurately recorded, and a method for calculating the vulcanization degree based on the Arrhenius formula is provided, so that a special calculation program is not needed for calculation, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of automobile accessories, in particular to a method for measuring the vulcanization degree of an inner tube. Background technique [0002] There is currently no technical solution for determining the degree of vulcanization of the inner tube. The existing solutions mainly rely on subjective evaluation or rough evaluation of the physical properties of the finished product. The disadvantages of the existing technical solutions are: the position of the carcass, base, rubber pad, etc. of the tire inner tube cannot accurately determine the degree of vulcanization. Only relying on subjective evaluation will cause inner tube over-vulcanization or under-vulcanization, over-vulcanization will cause waste of cost and energy, and under-vulcanization will seriously affect product quality. [0003] In view of the above problems, a method for measuring the degree of vulcanization of the inner tube is now provided. Cont...
