In this paper, we mainly talk about nitrile gloves inspection. NBR is prepared by emulsion polymerization of butadiene and acrylonitrile, and its products have excellent oil resistance, high wear resistance and good heat resistance. Made of high-quality nitrile rubber with other additives and refined and processed; Nitrile gloves do not contain
A lighter is a manually operated ignition device that uses petrochemical derivatives as fuel and is typically used to light cigarettes, cigars and pipes in a deliberate manner, as well as to light paper, wicks, candles and lanterns. The way of ignition is divided into a grinding wheel type and a button type, both of which satisfy the user’s need for two or more independent operations to generate a flame, so as to avoid the possibility of accidental ignition or auto-ignition.
Lighters are small fire devices，which is mainly used for fire and smoking, as well as for kitchens and other fires. The main components of the lighter are the ignition mechanism and the air storage box. When the ignition mechanism is working, the spark is emitted to the gas zone to ignite the gas. The ignition mechanism is the most active part of the evolution of the lighter, and it is also a more complex part. According to the characteristics of
Stainless steel is a kind of steel, which contains less than 2 % carbon ( C )is called steel, while more than 2 % is iron. The addition of chromium ( Cr ), nickel ( Ni ), manganese ( Mn ), silicon ( Si ), titanium ( Ti ), molybdenum ( Mo ) and other alloying elements in the steel during smelting, improves the performance of the steel and gives the steel corrosion resistance,
With the increasing number of cases of infection in COVID-19, masks have now become necessary items for people, and people’s awareness of wearing masks has been greatly “improved”. However, there are all kinds of masks on the market, and the prices are also different. How to correctly understand masks and purchase masks with protective ability has become the most concerned problem for everyone. At the same time, the inspection company has also made further matching inspections process for mask
