Method for carrying out surface density modification on boat piece of graphite boat
The invention relates to a preparation technology of photovoltaic manufacturing equipment parts, and aims to provide a method for performing surface density modification on boat pieces of a graphite boat. The method comprises the following steps: preparing an acidic solution A from a polyaminobenzene heterocyclic compound, an acid solution, an anionic surfactant and a proper amount of a solvent; putting a boat piece of a graphite boat with a clean surface into the solution A, standing and soaking for modification reaction; then continuously adding a solution B prepared from a nitroso compound and a proper amount of a solvent, and continuously standing and soaking so as to continuously carry out a modification reaction; and taking out the boat piece, washing the boat piece with deionized water, and drying the boat piece to obtain the boat piece for assembling the graphite boat. According to the method, the boat piece of the graphite boat is modified by utilizing diazotization reaction, so that the modified boat piece has the characteristics of high surface density and low pulverization degree. The process has the advantages of easily available raw materials and low cost; an aqueous solvent system is low in emission; the soaking or spraying process is adopted, operation is easy, and the technological process is few.
本发明涉及光伏制造设备部件的制备技术，旨在提供一种对石墨舟的舟片进行表面致密度改性的方法。该方法包括：取多氨基苯杂环化合物、酸液、阴离子表面活性剂和适量溶剂，配制成呈酸性的溶液A；将表面干净的石墨舟的舟片放入溶液A中静置浸泡进行改性反应；然后继续加入由亚硝基化合物和适量溶剂配制成的溶液B，继续静置浸泡以继续进行改性反应；取出舟片，用去离子水冲洗干净，烘干后得到用于组装石墨舟的舟片。本发明利用重氮化反应来改性石墨舟的舟片，使改性后的舟片具有表面致密度高、粉化程度低的特点。该工艺原料易得，成本低；水性溶剂体系，排放少；采用浸泡或喷涂工艺，操作简单、工艺流程少。
