Application of Polyurethane Products in Polysilicon Industry
Polysilicon materials and products have high requirements on purity during the production process, and it is necessary to avoid contamination during the production process and the formation of substandard products. In all kinds of gardens that cause pollution, an important source of pollution is metal objects. Therefore, in production, polysilicon and finished products must avoid contact with metal tools, and polyurethane products and polyurethane lined tools are a very ideal choice. At the same time, the polyurethane material is wear-resistant and elastic, which also plays a good role in buffering and maintenance of the product during the production process, and is also of great benefit to the service life of many tools.
1. The common applications of polyurethane products in the production of polysilicon are:
Polyurethane rake, polyurethane rake for polysilicon production, various polyurethane shovels, scrapers;
Polysilicon pallet box bushing, silicon rod pallet box bushing, polysilicon transfer box liner;
Silicon rod transfer car polyurethane overall bushing, polyurethane box, silicon rod transfer car bushing, transfer car protective cover;
Silicon rod car bushing, polyurethane box;
Polyurethane sieve basket for polysilicon cleaning, sieve tray, cleaning basket, cleaning machine tool loading basket polyurethane bushing;
Robotic arm gripper and clamping pad gripper for polycrystalline silicon rod production;
Polycrystalline silicon rod crushing table polyurethane bushing, crushing table PU groove, crushing table maintenance cover;
Polyurethane bushing for polysilicon crushing table, triangular crushing table lining, polyurethane lining;
Polyurethane box and carbon head material box lining for polysilicon sorting equipment;
Various polyurethane shovels and polyurethane dustpans for polysilicon storage;
The traditional method of polysilicon to avoid pollution: the traditional protective materials mostly use plastic materials such as PVC, tetrafluoroethylene, PE and ABS, which are prone to brittleness, slag loss, wear resistance, durability and the appearance of protective products during use. Structural defects and other problems plague production efficiency and product quality. Through on-site investigation and trial, the polyurethane elastomer suitable for this industry has been developed, which greatly improves the above defects, improves the product quality and production efficiency of polysilicon, and the excellent durability also means lower costs.
2. Why choose polyurethane?
High wear resistance of polyurethane: Polyurethane elastomer is the most wear-resistant polymer material currently known. Wear-resistant means that the occurrence of debris is reduced, pollution is reduced, and the service life and cost performance of the product are also improved. .
High strength of polyurethane material: The excellent tensile and tear strength and impact resistance of polyurethane elastomer make the material suitable for more arduous tasks, such as high-frequency use of crushing table protective sleeves.
Excellent elongation at break: The elongation at break of polyurethane elastomers is usually 300-800% or even greater, which means that polyurethane will not easily break the material even if it exhibits local large deformation during extreme use. , to reduce the slag and other undesirable phenomena of the material;
Excellent elasticity and recovery resilience: Polyurethane elastomer has excellent elasticity and recovery properties. In contact with extremely hard and sharp polysilicon materials, even if it is repeatedly punctured, it can still heal itself, and it is not easy to cause material damage. Adhere to lasting protective features;
The polyurethane material is easy to form and the process is simple: the flexible process of the cast polyurethane elastomer makes it possible for large-sized and complex workpieces. It is very suitable for the individual needs of different manufacturers and different products;
The material has high purity and will not cause pollution to polysilicon: the polyurethane protective products we supply are all pure polyurethane materials, without plasticizers and without any other fillers, so there will be no plasticizers and fillers in the process of product use. The precipitation of additives further contaminates polysilicon.
