There are many kinds of hardware lock materials on the market, the processing technology is diverse, and the specifications are not the same. Then how to choose the hardware lock on the door, the author has compiled some hardware manuals, which explain in detail how to choose the hardware locks. A look at the lock material market, the lock material is basically divided into stainless steel, copper, zinc alloy. High-strength stainless steel, strong corrosion resistance, no discoloration, is the best lock material; copper is more versatile, mechanical properties are superior, and the price is higher; the lock high-quality zinc alloy is strong and wear-resistant, corrosion-resistant, and easy to form. Mostly used for mid-range locks. Second, look at the surface treatment of locks. The surface treatment is roughly divided into three types: electroplating, spraying and coloring. The locks form a dense protective film on the surface of the product through surface treatment, which acts as anti-corrosion and anti-rust, making the lock more beautiful and durable. The dense protective film is also a standard for measuring the quality of locks. The locks of good quality are mostly plated, the coating is fine and smooth, even and moderate, the color is bright, and there are no signs of bubbles, rust and oxidation. Third, look at the implementation of locks. Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. We can feel the quality of the locks. Generally speaking, the heavy lock has a relatively high quality; the lock body can not be pointed, and the tip is easy to injure, especially the lock handle end, the lock tongue and the lock body are three positions; the lock spring is good. Flexible opening, high sensitivity and long service life. There are also many styles of locks, so be sure to keep in mind the style of the interior doors.
Pvc Anti-corrosion Tape, according to different uses, is also called PVC air-conditioning cable tie. PVC Anti-corrosion tape, also known as PVC outer protective tape, is mainly used for anti-corrosion protection of various pipes. The name of the product comes from the base material of the product - polyvinyl chloride diaphragm. So it has the durability and corrosion resistance of PVC. , Easy to wrap, suitable for low temperature conditions, but also suitable for elbows and irregular surfaces. Widely used in ordinary steel pipes, galvanized pipes, stainless steel pipes; anti-corrosion of air-conditioning pipelines.
