Is the anticorrosion treatment of cast iron gates necessary?


With the wide application of cast iron gates, a series of problems have also followed. Among them, the anti-corrosion problem of cast iron inlaid copper gates has attracted much attention from customers. Only the anti-corrosion and anti-rust work of the equipment can be realized. With regard to this issue, the Qianjin Hydraulic Engineering Department makes the following summary based on years of production and sales experience, and hope to help you:


The necessity of anti-corrosion treatment for cast iron gates:


Cast iron gates often have some defects or faults after long-term operation or use: the corrosion of the steel gate; the jamming of the gate operation (formed by the displacement of the gate leaf, the deformation of the gate leaf, and the falling of the walking support); the gate stops Water loss, severe water leakage; defects or faults of door leaf and embedded parts due to cavitation, corrosion, abrasion, etc. If these defects or faults are not dealt with and removed in real time, they will seriously affect the safe operation of the gate. Therefore, not only must pay attention to the task situation and carry out real-time protection and maintenance, but also repair the gates on schedule.


Specific methods for anti-corrosion of cast iron gates:


The metal parts of cast iron gates and steel structure gates should be treated with rust and corrosion protection on schedule. The commonly used anti-corrosion methods for steel gates are paint maintenance and metal spraying maintenance. Before protective treatment, it is necessary to carefully remove rust on the outside. Common methods include manual shoveling, wire brushing, and sandblasting to remove rust. It is required to remove old paint and rust, rust spots, oil, dust, acid and alkali, and salt residues, and then scrub with pine nasal spray or turpentine to make it all show off the gray-white metal nature, and insist on being dry and inevitably rough The final coating must have a certain thinner to make it reach a suitable consistency to facilitate the construction operation. Ordinary supporting thinner all year round. The anti-rust paint thinner should not be added too much, generally it is better not to exceed 2% to 3% of the weight of the paint. Zinc spraying is a useful way to maintain steel structure. It has a long life span, generally up to 20 years, but it is expensive and requires special equipment.
