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,
On the evening of April 29, according to the documents issued by the China General Administration of Market Supervision, the Chinese government will focus on the supervision of masks and other materials, and will carry out special rectification of meltblown fabric industry in China.
Meltblown cloth is the core raw material for masks. Recently, the meltblown cloth industry has seen serious chaos, with prices soaring and plummeting, from RMB18,000 to RMB700,000, up nearly 40 times. In the recent part meltblown cloth
