The dry powder fire extinguisher is suitable for the initial fire of flammable, flammable liquids, gases and charged equipment. The ammonium phosphate dry powder fire extinguisher can be used for the initial fire of solid materials in addition to the above types of fires. But none can save metal fires.
Instructions
When the fire is extinguished, the fire extinguisher can be hand-carried or shoulder-fired and the fire extinguisher can quickly go to the fire. The fire extinguisher is put down about 5 meters from the burning place. If you are outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher used is of the plug-in type, the operator should tighten the spray gun with one hand, and open the lifting ring on the gas bottle. If the opening of the gas cylinder is hand-wheel type, unscrew it counterclockwise and rotate it to the highest position, then lift the fire extinguisher. When the dry powder sprayed out, quickly aim at the root of the flame. If the dry powder fire extinguisher used is a built-in gas cylinder or a pressure storage type, the operator should first unplug the safety pin on the opening handle, then live the nozzle part at the front end of the spray hose, and the other hand will open the pressure of the pressure handle. Next, turn on the fire extinguisher and extinguish it. When using a fire extinguisher or pressurized fire extinguisher with a spray hose, the pressure handle should always be pressed down by one hand and cannot be released, otherwise the injection will be interrupted.
Use caution
When using ammonium phosphate dry powder fire extinguishers to fight solid flammable materials, fire should be directed at the place where the combustion is most intense, and fire should be performed up and down and left and right. If conditions permit, the user can use the fire extinguisher to spray along the four sides of the combustion, so that the dry powder fire extinguishing agent evenly sprayed on the surface of the combustion until the flame is completely extinguished.
The use of a cart type dry powder fire extinguisher is the same as the use of a portable dry powder fire extinguisher.
Metallized ceramics
We manufacture a variety of refractory metallized ceramics, mainly including Metallized Ceramic Insulator, Metallized Ceramic Tube, Metallized Ceramic Ring, Metallized Ceramic Substrate, Ceramic metallized cylinders.These metallized ceramics is fit for high vacuum, high voltage and high pressure applications due to their exceptional insulation strength, superb bonding strength and excellent metal to ceramic joining hermeticity.
We offer a selection of metallization types to meet special needs via screen printing, pad printing, brushing, the regular types as below:
â—Ceramic body base + Molybdenum (Mo/Mn) metallization.................â—Ceramic body base + Silver(Ag) plating
â—Ceramic body base + Tin (Sn) plating.................................................â—Ceramic body base + Molybdenum (Mo/Mn) + Nickle plating
â—Ceramic body base + Tungsten (W) + Gold plating........................... â— Ceramic Substrate + Copper(Cu) plating.
Based on in-house comprehensive manufacturing equipment from shaping to electroplating process, we have prototyping to high volume production capability. It helps us to make the dimensions consistency very well, also, helps us to offer a more competitive cost to our customers. Whatever, a very small trial order for R&D program, or extremely high volume need for cost down, we will find a optimal solution there to meet your needs.
These metallized ceramics are widely used in ceramic to metal, ceramic to ceramic joining technology in electrical, electronics, high vacuum technology, medical technology, sensor technology, the typical application like the ceramic insulator/body in vacuum interrupters, vacuum capacitors/thyristor, gas discharge tube, electron tubes, current feedthrough, X-ray tubes, power switches and so on.
