Embodiment 1

[0020] The dipping process of the compensation chain includes the following steps:

[0021] (1) Surface treatment: first, derust and dry the compensating chain at 90°C; then put the compensating chain in a sealed chamber and send a mixed gas of hydrogen and oxygen into the sealed chamber to ignite it with a spark plug. The mixed gas explodes and releases a large amount of heat. The instantaneous temperature is as high as 3000°C and the explosion time is 0.6. On the one hand, the surface burrs of the compensation chain are burned off, and on the other hand, the compensation chain is preheated;

[0022] (2) PVC immersion: Make the compensation chain pass through the immersion liquid tank, ultrasonic homogenization channel, curing heat preservation oven and water cooling tank in sequence. When the compensation chain passes through the immersion liquid tank, it is completely submerged by the PVC immersion liquid, and the compensation chain passes through When curing the heat prese...

Embodiment 2

[0027] The dipping process of the compensation chain includes the following steps:

[0028] 1) Surface treatment: first, derust and dry the compensating chain, the drying temperature is 100°C; then put the compensating chain into the sealed chamber, send the mixed gas of hydrogen and oxygen into the sealed chamber, after being ignited by the spark plug, mix The gas explodes and releases a lot of heat. The instantaneous temperature is as high as 3400°C and the explosion time is 0.7. On the one hand, the surface burrs of the compensation chain are burned off, and on the other hand, the compensation chain is preheated;

[0029] (2) PVC immersion: Make the compensation chain pass through the immersion liquid tank, ultrasonic homogenization channel, curing heat preservation oven and water cooling tank in sequence. When the compensation chain passes through the immersion liquid tank, it is completely submerged by the PVC immersion liquid, and the compensation chain passes through Wh...

Embodiment 3

[0034] The dipping process of the compensation chain includes the following steps:

[0035] (1) Surface treatment: first, derust and dry the compensating chain, the drying temperature is 120°C; then put the compensating chain into the sealed chamber, send the mixed gas of hydrogen and oxygen into the sealed chamber, after being ignited by the spark plug, The mixed gas explodes, releasing a lot of heat, the instantaneous temperature is as high as 3800°C, and the explosion time is 0.8. On the one hand, the surface burrs of the compensation chain are burned off, and on the other hand, the compensation chain is preheated;

[0036] (2) PVC immersion: Make the compensation chain pass through the immersion liquid tank, ultrasonic homogenization channel, curing heat preservation oven and water cooling tank in sequence. When the compensation chain passes through the immersion liquid tank, it is completely submerged by the PVC immersion liquid, and the compensation chain passes through ...

Abstract

The invention relates to a compensation chain plastic dipping process. The compensation chain plastic dipping process comprises the following steps: surface treatment: firstly, a compensation chain is derusted and dried at a drying temperature of 90-120 DEG C; then, the compensation chain is put in a sealed chamber; hydrogen and oxygen mixed gas is fed in the sealed chamber; after a spark plug is ignited, the mixed gas explodes to release out a lot of heat; the transient temperature is high up to 3000-3800 DEG C; the explosion time is 0.6-0.8; on the one hand, burrs on the surface of the compensation chain are burnt off; and on the other hand, the compensation chain is preheated; and PVC plastic dipping: the compensation chain passes through a plastic dipping liquid tank, an ultrasonic homogenization channel, a curing insulation drying way and a water cooling tank in sequence; when the compensation chain passes through the plastic dipping liquid tank, the compensation chain is totally immersed by PVC plastic dipping liquid; and when the compensation chain passes through the curing insulation drying way, the curing time is 2-3 minutes, and the curing temperature is 180-200 DEG C. The plastic dipping process has the advantages of high plastic dipping efficiency and good plastic dipping effect.

Description

technical field [0001] The invention relates to a plastic dipping process of a compensation chain. Background technique [0002] The compensation chain is generally used in elevators. Its structure is an iron chain wrapped with PVC rubber composite material. It is used to compensate the weight of the steel wire rope to make the elevator run smoothly. [0003] In order to make the elevator run safely and smoothly, and to achieve the effect of quietness and comfort, it is usually necessary to perform noise reduction processing on the compensation chain. At present, there are several types of compensation chains on the market: 1. Fiber-wrapped compensation chains, which can reach a ladder speed of 4m / s and can be used in various cold and harsh environments. They are the compensation chains with the best performance at present, but the price is relatively high. . 2. The all-plastic compensation chain can reach the elevator speed of 3m / s. The appearance is a cable-like PVC stru...
