Answer: (1) First, we must understand the cause of the fire, and adopt different methods of extinguishing for different causes and combustion of different objects. Generally speaking, if it is caused by electric fire, first open the electric knife; if it is caused by burning, first extinguish the fire source; if the substance soluble in water or the substance that does not react with water catches fire, you can use water to extinguish the fire. If the water-insoluble organic solvent is burning, only use CO: etc. to extinguish the fire. Therefore, it is crucial to judge the cause of the fire and the situation on the spot. Otherwise, not only will it not extinguish the fire, but it will increase the possibility of the fire. (2) Dissipate the fire, immediately turn off all heating equipment, and move all nearby flammable (especially organic solvents) or explosive materials to a distant place. It is worth noting that when extinguishing the flame, do not overturn nearby instruments containing organic agents or break the burning container containing flammable substances, which will often exacerbate the fire. (3) Take effective fire-fighting measures at a speed. There are three possibilities for extinguishing the flame: 1 to remove the burning substances; 2 to cool the burning substances below the burning point, generally available water, but not all occasions; 3 to insulate the combustion products from the air And extinction, this is the most common method of extinguishing fire.
Safe: the laser is enclosed in the laser protection glass to ensure the laser not polluted and protecting the operator from laser radiation.
Autofocus: the marking focus height can be automatically adjusted to the best position according to the different heights of the workpieces.
Automatic protective door:the protective door at DO+4 laser protection grade will automatically rise or fall without manual operation in the marking process.
Ezcad control software: lagal Jichengzi control software
DO+ 4 laser protective grade:it has been certified by the ECS and DIN EN 12254:2010 + AC: 2011 standard.
100000 + hour working life: the laser source enjoys a 100,000-hour working life and ensures your confidence in the life of the machine. At the same time, the whole machine costs only 0.5kw`s power to run.
