With the progress of life, many convenient and fast products have replaced the old objects in the past, but while we enjoy the convenience, these new products have also brought some safety hazards to our lives.
The original intention of the gas detector
Natural gas and liquefied gas are the first to bear. As a new energy source, there are also hidden safety hazards behind its quick advantage. And because the gas is flammable and explosive, if you do not close the valve or gas leak in time, wait until If the concentration is too high, the consequences can hardly be imagined.
Gas detector function
The gas detector will detect the concentration of natural gas and liquefied gas in the air. When the gas concentration exceeds a certain range, the alarm will automatically sound to remind everyone to check whether the natural gas and liquefied gas leak, so as to successfully avoid the risk of fire and other dangers. occur.
For many residential communities and restaurants, there are still many hidden dangers. The kitchen gas valve forgets to turn off or the pipeline leaks. If you do n’t pay attention, you may enter the abyss. You can install a gas detector for early warning, and configure a robot or solenoid valve. Automatically close the valve and block the gas pipeline to avoid major losses caused by gas leakage.

Precautions for gas detector installation
1. The gas detector should be installed in an area free of vibration, shock and electromagnetic interference to prevent affecting the normal operation of the detector.
Second , the installation of household gas detectors should be within 1.5 meters from the gas source, and a probe should be placed at 20 square meters lower in other gas-consuming places. The actual situation will be determined according to the place.
3. The detector probe is mainly a detection element that contacts the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a spherical shape, and its outer surface is attached with rare metals such as platinum and palladium. Therefore, be careful when installing to avoid breaking the probe.
Fourth, the installation height of the detector should generally be 1.6-1.7m, so as to facilitate maintenance personnel to carry out daily maintenance.
Advantages of K730 gas detector

2. The product comes with battery valve and manipulator output function, which can automatically shut off the gas.
3. Pass the inspection of fire protection products, and issue certificates and test reports.
4. The company was awarded the CCTV7 brand show of CCTV, and was awarded the title of "Anti-theft Alarm".
Introduction of diamond saw blade
Diamond saw blade is a kind of cutting tool, which is widely used in the processing of hard and brittle materials such as stone and ceramics. Diamond saw blade is mainly composed of two parts; the base body and the Cutter Head. It is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut is because it contains diamond, which is currently the hardest substance. , it frictionally cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.
Manufacturing Process Classification
1. Sintered diamond saw blade: It is divided into two types: cold press sintering and hot press sintering, which are formed by pressing and sintering.
2. Welding diamond saw blades: divided into two types: high-frequency welding and laser welding. High-frequency welding welds the cutter head and the substrate together through high-temperature melting media, and laser welding uses high-temperature laser beams to melt the contact edge of the cutter head and the substrate to form metallurgy combine
3. Electroplated diamond saw blade: the blade powder is attached to the substrate by electroplating.
Appearance classification:
1.Continuous edge saw blade: continuous sawtooth diamond saw blade, generally made by sintering method, commonly used bronze binder
2. Segment head type saw blade: the saw teeth are broken, the cutting speed is fast, suitable for both dry and wet cutting methods
3. Turbine-type saw blade: Combining the advantages of 1 and 2 above, the saw teeth continuously present a turbine-like uniform convexity, which improves the cutting speed and increases the service life.
