I have questions regarding the installation of polysilicon equipment
Thread Content
Is it necessary to remove oil and grease from the production equipment, process pipelines, instruments, valves, etc. during installation in the polysilicon production process? Why is oil and fat removal necessary? What are the consequences if oil removal and degreasing are not carried out? I’m a newcomer to the polysilicon industry; I hope everyone here can offer me some guidance! Thank you!
It will contaminate polysilicon; the impurity content in polysilicon is relatively low
There are high requirements for this issue in the polysilicon industry. Generally, pipes, equipment, fittings, and valves all require cleaning in two stages. The cleaning methods used at different stages (before and after installation) vary. If it is not cleaned, it will have a significant impact on the purity and quality of the product. At the same time, controlling these parameters also presents difficulties.
It is indeed to reduce impurities in the production process. The production of polysilicon imposes very strict requirements on the cleanliness of the production equipment and the production environment!
I see now; the need for degreasing in the polysilicon industry stems from the requirements regarding purity!
