Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.

6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.

Varnish cambric electrical insulation tape is made of straight-cut woven cotton fabric. Its fabric is primed with oil and coated in an electrical insulating finish. The varnish ensures that the tape remains intact as currents pass through the wire.

Moreover, fire-resistant drywall tape is typically made from materials including fiberglass and special polymers that enhance its performance during a fire. These materials can withstand higher temperatures and resist melting, which contributes to maintaining the integrity of the drywall installation. Builders and contractors are increasingly recognizing that investing in fire-resistant materials, including tape, is not just about compliance with codes but truly about prioritizing the safety of occupants.
