Problems solved by technology

[0002] As we all know, in the vulcanization process of semi-steel tires, steam and superheated water are used to vulcanize various semi-steel tires. Steam vulcanized tires tend to be overvulcanized, and the quality of the produced tires is unstable. The efficiency of water vulcanization is too low

Embodiment Construction

[0010] The present invention comprises the following steps, a. Filling with saturated steam for 1.5 minutes, filling the vulcanization bladder with saturated steam with a temperature of 206°C to 214°C and a pressure of 1.7Mpa to 1.9Mpa, such as the process conditions of steam within 1.5 minutes When the temperature and pressure do not reach the standard value, the computer will automatically delay the vulcanization in the nitrogen filling stage of step e; b. Inflate saturated steam according to the specifications of the tire, and keep the temperature in the vulcanizing bladder at 206°C to 214°C and the pressure to maintain At 1.7Mpa~1.9Mpa, the steam filling time is calculated according to the tire temperature data measured by the thermocouple, using the Arrhenius equation to calculate a reasonable time to achieve the purpose of energy saving; c. Then switch the steam and fill according to the tire specifications Inflate nitrogen, the temperature of nitrogen is 15℃~35℃, the pur...

Abstract

The invention discloses a method for rubber vulcanization of a semisteel tire. The method comprises the steps of: a, filling saturated steam for 1.5minutes, and filling saturated steam with the temperature being 206-214 DEG C and the pressure being 1.7-1.9Mpa into a vulcanized bag; b, filling saturated steam according to the specification of the tire, and calculating the proper steam filling time by utilizing the Arrhenius equation according to the tire temperature data measured by a thermocouple; c, filling nitrogen with the temperature being 15-35 DEG C and the pressure being 2.4-2.6Mpa according to the specification of the tire; d, detecting the leakage and retaining the pressure for 1minute, releasing the tire normally if the initial pressure of the nitrogen in the vulcanized bag is 2.4-2.6Mpa and is more than 2.3Mpa after 1minute, abandoning the tire after the vulcanization is completed if the pressure is less than 2.0Mpa, and conducting the nitrogen filling step and automatic delay vulcanization if the pressure is between 2.0 Mpa and 2.3Mpa; e, filling nitrogen for 1minute; f, recovering the nitrogen for 0.3minute; g, discharging the residual mixed water and steam, and the setting the steam discharging time as 0.1minute; and h, vacuuming the vulcanized bag for 0.4minute, and then demolding the vulcanized tire.

Description

technical field [0001] The invention relates to the field of tire production, in particular to a semi-steel tire rubber vulcanization method. Background technique [0002] As we all know, in the vulcanization process of semi-steel tires, steam and superheated water are used to vulcanize various semi-steel tires. Steam vulcanized tires tend to be overvulcanized, and the quality of the produced tires is unstable. The efficiency of water vulcanization is too low. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a semi-steel tire rubber vulcanization method, using steam and nitrogen to vulcanize various semi-steel tires can make the production energy-saving and environmentally friendly, and the quality of the semi-steel tires produced Stablize. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a semi-steel tire rubber vulcanization method, which is charac...
