Introduction
GB/T 33091—2016 Interpretation of the Polyurethane Sieve Plate Standard
1. Background and Significance of the Standard
Polyurethane sieve plates are important equipment components in the mining, coal, water conservancy and other industries, and their performance directly affects the material screening efficiency and service life. The formulation of the GB/T 33091—2016 standard fills the gap in this field in China and provides an important basis for product quality and technological progress.
The standard was drafted by Shandong Yinuowei Polyurethane Co., Ltd. and other units, combining the actual needs of the industry with advanced manufacturing technology, reflecting a high level of technology and practicality.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 33091—2016 | International comparison | Industry characteristics |
|---|---|---|---|
| Classification and structure | Divided into three categories: relaxation screen plate, tension screen plate and plate screen plate, with clear material and structural requirements. | In line with international standards, highlighting the performance indicators of elastomers. | Applicable to a variety of industrial scenarios. |
| Technical requirements | Covering key parameters such as appearance, dimensional tolerance, hardness, peel strength, etc. | Emphasis on wear resistance and tensile properties. | Combined with domestic production reality. |
| Test method | Quote GB/T 528, GB/T 529 and other standards to ensure that the test method is scientific and reliable. | Consistent with international general methods. | Highlight practical operability. |
3. Recommendations for Standard Implementation
Case Study: Application of Polyurethane Screen Plate in Mines
A mining enterprise adopted the GB/T 33091-2016 standard and selected 85A polyester tension screen plate (labeling example: polyurethane screen plate - Z - 1mm - 500×300×20 - 85A - polyester type - GB/T ××××—××××). After one year of use, the screening efficiency increased by 15% and the equipment maintenance cost decreased by 20%.
Through standardized management, the company has achieved:
- Stability of product quality
- Optimization of production costs
- Standardization of after-sales service
4. Analysis of the evolution of standard technology
From material selection to production process, polyurethane sieve plates have evolved from a single type to diversified development. The release of GB/T 33091-2016 standard marks that this field in China has entered a new stage of standardization and systematization.
Future technological development will focus on:
- Optimization of high-performance elastomer formula
- Intelligent detection method
- Green and environmentally friendly production process
