Embodiment Construction

[0027] In the present embodiment, a kind of novel giant tire retreading process, its tire retreading process comprises the following operation steps:

[0028] Step 1: Waste giant tires enter the factory; first wash and dry them

[0029] (1) The selection of carcass should be strictly required, the grinding line should not exceed 5mm, foreign objects such as stones and iron nails on the tire surface should be removed, internal inspection, and the internal test of the tire should be knocked with a small hammer to judge whether there is any void phenomenon;

[0030] (2) Check whether the internal tire is damaged, use a long-handled awl to remove foreign matter on the surface of the wound, carefully test the depth and range of the wound, make relevant marks and judge whether it exceeds the allowable range;

[0031] (3) Remove foreign objects on the inner surface of the tire, and retreading can only be carried out after passing the above inspections;

[0032] Step 2: Grinding the ...

Abstract

The invention discloses a novel giant tyre retreading technology. Air is isolated by adopting a high-temperature-resisting plastic paper sleeve more than 200 DEG C; a tyre with an inner tube is sealed through a steel ring side plate; a tyre without the inner tube is sealed through an inner sleeve and an outer sleeve; inner gas must be introduced outside a tank; in the vulcanization process, the air pressure in the tank must reach 6kg, and then vulcanization is carried out; the vulcanization temperature needs to reach 115 DEG C to 117 DEG C, and the vulcanization time is begun to be recorded; after vulcanization is completed, gas in the plastic paper sleeve should be exhausted, and meanwhile gas in the vulcanization tank and gas in the tyre are exhausted; when it is determined that pressure in the vulcanization tank and the tyre is zero, the tank is opened, the tyre is pushed out along a guide rail, and the plastic sleeve and the steel ring are disassembled; the giant tyre with the maximum size in the Asia can be retreaded; the repairing and retreading problem of the damaged giant tyre can be solved, the abrasion performance of the giant tyre can be obviously improved, the tyre use cost by an enterprise is reduced, the pollution, caused by waste tyres, to the environment is prevented, and the waste tyres can be effectively recycled.

Description

technical field [0001] The invention relates to a new giant tire retreading process. Background technique [0002] Giant tires are generally called giant tires with a tire diameter of 2.6m and a width of 0.8m or more. The price of giant tires has been rising year by year in the international tire market in recent years, and the supply is in short supply. The damage of giant tires mainly includes: The first is cut and peeling, which means that the giant tire is not dismantled and repaired in time after being cut during operation, but after continuing to run for a period of time, the tire tread will be partially peeled off, empty, and blocks, etc. Phenomenon. According to statistics, the giant tires that are scrapped due to cuts and scrapped during the rain and snow season account for more than 30% of the total amount of scrapped tires in the whole year. The stress on the tires of the mining truck is uneven during driving, which causes the wound to spread. Due to the strong...
