Section 7 Knowledge of Paint Materials
Home improvement can not be separated from the paint as a decorative material, use paint to choose environmentally friendly products. Currently, over a thousand kinds of paints have been sold on the building materials market, but there are commonly used oils, mixed oils, thick paints, tempered paints, varnish, and so on.
Qingyou, also known as cooked oil and paint oil, is one of the basic paints used to decorate doors and windows, wall skirts, heating covers, and matching furniture in home renovations.
Thick paint, also known as lead oil. It is widely used as a base coat, and it can also be used as a finish. Suitable for low-demand building and wood primer, filling materials for water pipe joints.
Blend oil is also called blend paint. Suitable for indoor and outdoor metal, wood, silicon wall surface.
The commonly known as lacquer varnish is a clear paint that does not contain pigments. Mainly applied to wood, furniture and so on. Objects that are susceptible to moisture and heat should not be used.
The enamel is based on clear varnish and is made by adding pigments. The coating is dry with a magneto-optic color. It is suitable for metal screen meshes.
Anti-rust paint has zinc yellow, iron red epoxy resin primer, tough and durable paint film, good adhesion, if used in conjunction with ethylene phosphating primer, can improve heat resistance, salt spray resistance, applicable to coastal areas and temperature Tropical metal material primer.
Organic solvents such as turpentine, turpentine, gasoline, acetone, ether, etc. used in alcoholic and alkyd paints are unpleasant. Use special care when choosing quality products. After the room is painted, it must be properly ventilated. After ventilation, it can stay.
Polyester paint:
It is a thick paint made of polyester resin as the main film forming material. The paint film of polyester paint is full and the layer is hard. Polyester paints also have varnish varieties called polyester varnish.
Polyester paints need to be cured during the construction process. The amount of these curing agents accounts for one-third of the total paint content. These hardeners are also called hardeners and their main component is TDI (toluene diisocyanate). These TDIs that are in a free state will turn yellow, which will not only make changes to the furniture, but will also cause yellowing of adjacent walls. This is a major drawback of polyester paints. A yellowing-resistant polyester paint has appeared on the market at present, but it can only achieve "yellowing resistance." It cannot yet be completely prevented. In addition, free TDI beyond the standard can also cause harm to humans.
Polyurethane paint:
Polyurethane paint is polyurethane paint. Its film is tough, full gloss, strong adhesion, water resistance, wear resistance, corrosion resistance, is widely used in advanced wood furniture, but also for the metal surface. The main disadvantages are the blistering of the tide and the chalkiness of the paint film; as with the polyester paint, there is also a problem of yellowing. The varnish type of polyurethane paint is called polyurethane varnish.

Sub-controller of LED applying system. The DMX-S8 receives the pixel data frame sent by the RTP-S1500 Main Controller. According to the address set by itself, the corresponding data in the pixel frame is taken out. After the format is adjusted, the data is sent out from the controlling port at a specific timing sequence to control the LED light to change color. Set up 2 RJ45 network interfaces; When using unshielded Twisted Pair, the distance of transmission from the main controller to the sub-controller and sub-controller to sub-controller is more than 100 meters; Connect to the switch for network to extend the distance of transmission; Single controller can connect up to 16 computer; Automatically identify its position in the system; Set up 8 DMX512 controlling ports with auto-addressing function. The number of single-port controlling pixels is 170 full-color pixels, 512 monochrome pixels, and the type of connector is the pluggable terminal; Each port conduct optical isolation protecting to ensure the stability of the entire controlling system;
