Respirators are used more and more widely. Respirators are widely used in industrial and medical applications. They are mainly used in fire-fighting, chemical, shipbuilding, petroleum, smelting, factories, mines, etc. Respirators are often used under occupational safety guidelines. Workers are Before using the respirator, professional training is also required. In some workplaces, such as asbestos, or other harmful toxins or harmful chemicals are often required to wear a mask. And individuals are protected from chemical or biological hazards. After other use respirators include medical conditions such as severe asthma or chronic obstructive pulmonary disease (COPD).
In addition, there are also widely used underwater diving equipment, fire fighting fire extinguishers. Widely used in hotels, escape breathing apparatus in public places, emergency escape breathing apparatus.
A medical ventilator is an instrument for breathing a patient. The use of such a device also requires training or instruction before it can be properly used and maintained. When the patient suffers difficulty in breathing, the user wears a simple medical respirator with the help of medical staff. This kind of operation requires the relevant documents for the operation of simple respirator for medical use. Before the use, it must also carry out some tests on the patient, including respiratory and pulmonary function tests, and other physical conditions, as well as regular maintenance, maintenance, and inspection of the respirator. Working condition to ensure that the instrument is working properly
PVC RESIN SG5
In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.
