As a common metal material, brass is widely used in the production of various crafts and decorations due to its unique texture and plasticity. However, in order to meet specific aesthetic needs, it is sometimes necessary to perform imitation gold treatment on the surface of brass to give it a golden appearance. The following is a detailed description of the imitation gold treatment technology of brass surface.
I. The technology aims to transform the surface of brass into a bright, uniform and non-fading golden color through specific chemical treatment, thereby enhancing the added value and aesthetics of copper parts.
II. Overview of treatment agent
The treatment agent is a colorless and transparent liquid with a slight odor. It is suitable for a variety of brass materials, including but not limited to leaded brass such as 54# to 59# and standard brass such as 62# and 65#. Its pH value is greater than 7.0 and its specific gravity is less than 1.0. It can be operated at room temperature without additional equipment. The treatment process is simple and easy.
III. Treatment method
1. Pretreatment: Brass parts must first be polished to remove surface impurities and oxide layers, followed by degreasing and dilute acid activation treatment, and then washed and dehydrated for standby use.
2. Soaking treatment: Soak the pre-treated brass parts in the treatment agent, and keep turning them over to ensure uniform contact. The soaking time is about 10 seconds to 1 minute, and the specific time is adjusted according to actual needs.
3. Post-treatment: After the soaking is completed, take out the brass parts and wash them with water to remove the residual treatment agent, then dehydrate and dry them to obtain imitation gold copper parts.
IV. Precautions
1. Insulation method: The treatment agent should be insulated in a water bath, and avoid direct heating with a heater to prevent excessive temperature from affecting the treatment effect.
2. Safe operation: The treatment agent should be kept at a safe distance from open flames and heat sources, and the operation should be carried out in a well-ventilated area to prevent the accumulation of harmful gases.
3. Soaking time: The soaking time of brass parts needs to be flexibly adjusted according to actual needs to achieve the best imitation gold effect.
