Adhesive Tape Marking Example 1:
1000 B 9508 4.5T × 3.0 1000 NN5 indicates that the strength specification of the bucket type lifting belt is 1000N/mm. It was produced in August 1995, with an upper cover layer thickness of 4.5mm and a reinforcement layer, a lower cover layer thickness of 3mm, a belt width of 1000mm, and a core material of nylon canvas, totaling 5 layers.
Adhesive Tape Marking Example 2:
St1000 B 9508 5T × 5T 1200 φ 3.5 indicates that the tape specification is a steel wire rope core bucket type lifting belt, with a strength specification of 1000N/mm. It was produced in August 1995, with a thickness of 5mm for both the upper and lower cover layers and a reinforcement layer. The belt width is 1200mm, and the steel wire rope diameter is 3.5mm. Currently, this type of product complies with the chemical industry standard HG/T 2577-1994 "Rubber Lifting Belt".
This standard was revised in 2005 and is currently awaiting approval. The revised standard has been renamed as "Rubber or Plastic", and the strength specifications and width specifications of fabric core lifting belts and steel wire rope core lifting belts are consistent with those of general-purpose fabric core conveyor belts and general-purpose steel wire rope core conveyor belts, respectively. The performance of the covering layer is divided into three types: general environmental conditions (L-type), heat resistance not exceeding 150 ℃ (T3 type), and heat resistance of 175 ℃ (T4 type). The revised standard also specifies the punching and drilling of lifting belts.
Expand
The rubber lifting belt is made up of multiple layers of adhesive fabric, and the core of the belt should generally be covered with adhesive. According to different usage temperatures, it can be divided into heat-resistant lifting belts and ordinary lifting belts; According to the different core materials, it can be divided into full cotton, polyester cotton interwoven, nylon, and EP lifting belts. According to different performance characteristics, lifting belts can also be divided into heat-resistant lifting belts, ordinary lifting belts, etc. Improve the physical properties and grade of the covering adhesive: It is divided into strong wear (D-type), moderate wear (L-type), and heat-resistant type (T-type) according to the wear resistance and load of the conveyed material. Width specifications of lifting belts: The main specifications of lifting belts include 150, 200, 250, 300, 350, 400, 500, 600mm, etc.
