First look at the implementation of the standard for foreign hardware locks have very strict standards, so the quality of imported products is relatively high. We can feel the good or bad of our locks. In general, the feeling of heavy locks, the quality is relatively high; the lock body can not be exposed, the exposed point is easy to hurt, in particular, should pay attention to the lock handle end of the lock, the lock tongue and the lock body four positions; lock spring good locks Flexible opening, high sensitivity and long service life. Locks also have a variety of styles, and must be consistent with the style of the interior doors.
Secondly, the lock material on the lock material market is basically divided into stainless steel, copper and zinc alloys. Stainless steel has high strength, strong corrosion resistance and no discoloration. It is the best material for making locks; copper is more general, mechanical properties are superior, and the price is higher; locks are high-quality zinc alloys strong wear-resistant, strong corrosion resistance, and easy molding. Mostly used for mid-range locks.
Look again at the lock surface treatment surface treatment is roughly divided into three kinds of plating, spraying and coloring, the lock through the surface treatment to form a layer of dense protective film on the surface of the product, play a role in anti-corrosion and rust, make the lock more beautiful and durable. The dense protective film is also a measure of the quality of locks. Good quality locks are mostly plated. The coating is delicate, smooth, even and moderate, bright in color, free of bubbles, signs of rust and oxidation.
Dimming glass can be printed on the surface, using UV printing glass. The printed pattern can be selected at will. The printing effect is frosted effect, and the printed color can be mixed color. The size of smart glass can be cut at will, according to the effect you want. Ultra clear and transparent electronic control film: it is a new product based on ordinary PDLC dimming principle, replanning the production formula so as to overturn the traditional automotive film products, and expand the revolutionary field of automotive film products in the overall performance.
The transparency and atomization of PDLC dimming glass are determined by its internal liquid crystal molecules. After the alternating current, the liquid crystal molecules are arranged in order, and the incident light can pass through directly, and the glass is transparent. When there is no electricity, the liquid crystal molecules are disordered, the incident light scatters through, and the glass is atomized and opaque.
