Tarnish Resistance: After exposure to a spec草門ified tarnishing enviro我歌nment, there are only minor些舊 color changes. Gentl又市e brushing easil小件y removes any corrosion from the 化嗎alloy. | |
Corrosion Resistance: In a solution at (37±1)℃ for (7.0長來±0.1)d, the total metal ion r上時elease should not exceed 200μg/cm². | |
Contraindications: Patients allergic 多醫to cobalt, chromium,文會 and molybdenum metals. | |
Usage: 1. Embedding: Create a wax pat鄉著tern using a drilled chromium a外通lloy phosphoric high-tempera遠朋ture embedding material這船 on the duplicated model. Embe看吃d in a casting rin動她g. Once the phosphate, carbon-fr數事ee, high-temperature embedding materia兵得l begins to solidify, it can be baked制制 in an oven after one hour. After a影的pproximately one 身西hour of solidification友明, heat for dewaxing (around嗎雪 260℃), then heat the cast妹秒ing ring to about 知他1000℃ and maintain for over half an ho電美ur before casting. 2. Casting: Use a high-frequency centri什廠fugal casting machine. Melt the metal u舊愛ntil it collapses and exhibits u舞學niform brightness before casting.物我 Centrifuge: a. When using gas and oxygen for meltin理物g, the gas pressure should be 0話討.2MPa and oxygen pressure 2請件MPa. b. When using acet問風ylene and oxygen, the acetylene pres服錯sure should be 0.4MPa, and ox車學ygen pressure should be 2MP大議a. Heat a proper amount of 要身the hard drilled chromium all說錢oy in the centrifuge 算高until it's bright white. Cast immediat校高ely when the molten alloy fo理放rms a mirror-like dip. 3. Grinding and Elect麗子rolytic Polishing: Allow t睡照he casting ring to naturally cool i好對n the air for at l地睡east half an hour after casti服照ng. Do NOT immerse in water. Afte兒短r cooling, sandb月討last and polish t白雜he cast item, follo視秒wed by standard elec著作trolytic polishing. | |
Storage and Transpor雨場tation: This product doesnt require an男器y special storage conditions or usa票術ge terms. During transportatio還雪n, protect against rain, sno車湖w, or mechanical impacts, and avoid mix電年ing or transporting with corrosive mate話明rials. | |
Maintenance: No special mainten了吃ance or care is requir北綠ed for this product. Do not op火兒en the package before use. | |
