A processing method for granite fire board, firstly sawing natural granite into a plate, the surface of the plate is subjected to initial grinding, after initial grinding, and then placed on a fixed frame, and then the surface of the initial grinding is flame-sprayed. It is characterized in that the flame is sprayed with acetylene, oxygen and a spray gun, and the flame moves evenly on the surface of the plate. The moving speed is 120 to 250 mm per second, and the distance between the nozzle and the plate surface is 20 to 40 mm, and they are inclined to each other. The temperature of the flame is 800-1000 ° C. Before the flame is sprayed, the plate is sprayed first (to prevent the plate from burning when the flame is burned, and the water is heated to absorb heat). The processing method of granite fire board involves the processing technology of granite. First, the natural granite is sawn into a plate, and the surface of the plate is subjected to initial grinding, and then the initial grinding surface is flame-sprayed, so that the surface layer of 0.5 to 1 mm is peeled off. The granite material processed by this method exposes the true color of the stone, and has a simple, rough and natural feeling. Granite fire boards can be used on sidewalks, roads, indoor floors and walls. The liquefied gas and oxygen are burned through a high-temperature flame, and the uneven expansion due to heat is formed to have the same effect as the litchi surface, and has an anti-slip effect. First, construction deployment Project examples: sidewalk paving and platform paving. Stone specifications are: sesame ash granite fire board (49.7*29.7*6, 29.7*24.7*6), sesame black granite fire board (49.7*29.7*6), sesame gray granite blind board (29.7*29.7*6) and sesame Gray blind dot plate (29.7*29.7*6). Second, the main construction materials, machinery 1, material Cement: Generally use 32.5 grade slag Portland cement. The cement should have product certification certificate and factory inspection report. After entering the site, the strength, stability and other necessary performance indicators should be sampled and retested. The quality must conform to the current national standards. "General Portland Cement" GB175-2007 and other regulations. When there is doubt about the quality of the cement or the cement is shipped for more than three months, it must be retested before use and used as a result of the retest. Different types of cement should not be mixed. Water: Drinking water should be used. When other water sources are used, the water quality should comply with the current standard of the standard "Concrete Mixing Water Standards" JGJ63-2006. Sand: It is advisable to use medium and coarse sand with a hard texture and a sieve with a diameter of 5 mm. The mud content of the sand is not more than 3%. The variety and quality of sand should meet the requirements of the current national standard "Building sand GB14684-2001", JGJ52-2006 "Ordinary concrete sand, stone quality and inspection method standards". After entering the site, the sampling test is qualified according to the regulations. Concrete inspection and implementation GB/T 50081-2002 "Standards for test methods of mechanical properties of ordinary concrete". 2, machine tools Level ruler, ruler, box ruler, construction line, rubber hammer, small cart, iron shovel, cutting machine, mortar mixer, etc.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
