Embodiment Construction

[0021] The bushing plate shown in the figure is a known structure.

[0022] The present invention reduces the coating preparation and preparation and installation method of platinum bushing plate as follows:

[0023] 1. Coating powder 150±10g, Suzhou soil 10±2g, distilled water 150ml-170ml

[0024] Stir the weighed coating powder, Suzhou soil and distilled water in a ceramic container to form a uniform and relatively thin coating, and let it stand for 24 hours before use.

[0025] 2. Coating powder 150±10g, Suzhou soil 10±2g, distilled water 120ml-140ml

[0026] The weighed coating powder, Suzhou soil and distilled water are stirred in a ceramic container to form a uniform and relatively viscous coating, which is left to stand for 24 hours before use.

[0027] 3. Soak the polished tumbler in water for more than 8 hours and set aside.

[0028] 4. To clean the leakage board, clean and dry the leakage board with alcohol.

[0029] 5. For the leak board coating, evenly apply th...

Abstract

The invention relates to a coating capable of reducing use loss of platinum bushings and a preparation method thereof. The coating is formed by the coating materials prepared by the following materials in proportion: 140-160g of coating powder, 8-12g of Suzhou soil and appropriate distilled water. The bushing coating of the invention can effectively reduce the use loss of platinum and lower the production cost. With the bushing coating of the invention adopted, the loss is reduced by 4-6g year on year every cycle. The coating is especially suitable for the bushings used for drawing various medium-alkali and alkali-free glass fibers.

Description

technical field [0001] The invention relates to a platinum bushing used for glass fiber drawing to reduce platinum loss and a preparation method thereof, which is particularly suitable for drawing various types of bushings for medium-alkali and non-alkali glass fibers. Background technique [0002] At present, platinum-rhodium alloy is a precious and rare metal material, and there are very few mines in my country. With the continuous expansion of the glass fiber industry, its consumption has also doubled. At present, reducing the use loss of platinum can generate income for enterprises. High economic benefit. When platinum is in contact with oxygen at room temperature, PtO will be formed on the surface 2 , when heated to 450 °C in an oxidizing atmosphere, the PtO on the platinum surface 2 Volatilizes into gas phase PtO 2 , gas-phase PtO 2 Decomposes into Pt and O at temperatures above 510°C 2 . The decomposed Pt is deposited on the solid surface encountered or dissipate...
