Plastic films are more plastic materials used in daily life. The ones we usually see are mobile phone stickers, car stickers, wall stickers, plastic wrap, etc. In fact, plastic is ubiquitous in our lives, and plastic film is also one of them. Even the skin care products and cosmetics used by women are covered by a film in the form of plastic film. When it comes to pvc film, in fact, this kind of film is used in some fire fighting equipment, its main feature is that its flame retardancy is better. The use of this material is still very beneficial. In cities, during some quarters of change, the temperature difference between morning and night is large, and the dryness in some places is easy to cause fires. At this time, firefighters are needed to fight the fire. For these, many plastic materials can now be used in fire-fighting equipment and other fire-fighting equipment, playing a flame-retardant effect. Many of the flame retardants of these plastics are borrowed from pvc films. It can

Refrigerant, also known as refrigerant , is a working fluid used in refrigeration and air-conditioning systems to transfer heat energy and produce a freezing effect. When talking about refrigerant, most people think of air conditioners first. Indeed, in terms of daily life, air conditioners are installed in almost every household, and the frequency of application is quite high. However, today we are not talking about air conditioners, but air energy heat pumps that have similar principles to air conditioners. Air conditioners are mainly used for refrigeration, and air energy heat pumps are mainly used for heating. The heating principle of the heat pump is actually the inverse principle of air conditioning and refrigeration, which absorbs heat energy in the air through refrigerant. Therefore, it is not unreasonable to say that the refrigerant plays a key role in the heating of air energy. And what kinds of refrigerants are common in air? Let's take everyone to get to know them today

A stainless steel pipe is a steel product that you cannot do without whether in the house or in any commercial/industrial space. Inbuilt with all the qualities inherent in stainless steel, this pipe offer utmost reliability, which is very important wherever it is used. It is known to resist corrosion and oxidation, high temperatures, and allow for cleanliness and incurs low maintenance costs. It also helps to maintain the purity of materials which come in contact with it, while in use. Uses Some of the areas where you would find the use of the stainless steel pipe are installations for: Chemical Petrochemical Fertilizer Pulp and paper Marine Food Beverage Energy Process industries Customized Options The stainless steel pipe comes in a wide range of grades and sizes to suit the needs of different industry sectors. Apart from standard catalogue products, most of the manufacturers today also offer customized options to suit individual industry sectors. They can be customized in terms of

Stainless steel pipe is a hollow circular strip of steel, mainly used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial pipelines, as well as mechanical components. In addition, bending, torsional strength of the same, lighter, so it is widely used in manufacture of mechanical parts and engineering structures. Is also used in producing all kinds of conventional weapons, the barrel, shells and so on. Stainless steel safe, reliable, public health environmental protection and economic application of thin-walled pipes and new, reliable, simple and convenient connection method successful development, it has more advantages of the other pipe can not be replaced, engineering more and more the use will become increasingly popular, prospects are bright. With the implementation of China's reform and opening up policy, the national economy was the rapid growth of urban housing, public buildings and tourist facilities for the construction of

Toroidal transformer is a large type of electronic transformer, which has been widely used in home appliances and other electronic equipment with high technical requirements. Its main purpose is as a power transformer and isolation transformer. It is widely used in computers, medical equipment, telecommunications, instruments and lighting. In the past ten years, toroidal transformers have been produced in my country. So far, they have formed a considerable scale of production. In addition to meeting domestic demand, they are also exported in large quantities. Domestically, it is mainly used for audio equipment and automatic control equipment of home appliances, and quartz lamp lighting. Toroidal transformer is a competitive electronic transformer due to its excellent performance-to-price ratio, good output characteristics and anti-interference ability. Nanocrystalline materials also have the advantages of silicon steel, permalloy and ferrite. which is:    High magnetic induction: satu

The main purpose of  alloy steel pipe  is to be used in high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , After hot rolling (extrusion, expansion) or cold rolling (drawing). The biggest advantage of alloy steel pipe can be 100% recycled, which is in line with the national strategy of environmental protection, energy saving and resource saving. The national policy encourages the expansion of the application field of high pressure alloy pipe. At present, my country's alloy pipe consumption accounts for only half of the total steel products in developed countries. The expansion of the use of alloy pipes provides a broader space for industry development. According to the research of the expert group of the Alloy Pipe Branch of the China Special Steel Association, the demand

Polypropylene meltblown electret masterbatch  can increase the density and depth of the charge trapping energy trap in  melt blown nonwoven fabric ,effectively release negative ions and store charge to improve the comprehensive filtration efficiency and thermal attenuation resistance of meltblown nonwoven fabric. Next, Qingdao Sainuo  electret masterbatch manufacturer  will take you to know his relevant information.   Product Advantage of Polypropylene meltblown electret masterbatch: 1. No need to add new equipment, no need to significantly adjust the existing melt-blown non-woven production process( melt blown process ). 2. Does not affect the normal cleaning cycle and service life of the spinneret. 3. Under the condition of the same fiber fineness and the same weight, it can reduce the resistance of the non-woven fabric products, and at the same time improve the filtration efficiency and self-sterilization performance of non-woven fabric products. Filtration efficiency ≥95%.   Polypr

Stainless steel pipe  is a hollow long round steel material, which is widely used in industrial transportation pipelines and mechanical structural parts such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchenware. Stainless steel pipes generally use three hardness indexes of Brinell, Rockwell, and Vickers to measure their hardness. 1. Brinell hardness Among the stainless steel pipe standards, Brinell hardness is the most widely used, and the hardness of the material is often expressed by the indentation diameter, which is intuitive and convenient. However, it is not suitable for steel pipes with harder or thinner steel. 2. Rockwell hardness The Rockwell hardness test of stainless steel pipe is the same as t

What is amorphous strip ? There are usually two kinds of materials which people touch in daily life: one is crystalline substance and the other one is an amorphous material. The so-called crystalline data means that the arrangement of atoms in the information follows specific rules. Conversely, if the inner atom placement is at an irregular condition, it is an amorphous substance. For ordinary metals, the inner atom placement is orderly and belong to the crystalline substance. Scientists found that following the alloy melted, the internal atoms were in a playful state. When the metal begins to cool, the atoms will occur after the temperature drop and gradually placed in order according to the certain crystalline state, forming a crystal. When the heating process is fast and the atoms are condensed before they are relocated, an amorphous alloy is generated. It's a quick coagulation process used to prepare the amorphous metal. The high-temperature molten steel in the molten condition
