Q: What are the raw materials of foam plastics and how do they come out?: The foaming agents for epoxy resins are two types: physical foaming agents and chemical foaming agents. Physical foaming agents are mainly low boiling liquid, such as three chloro methane (F11), three chlorine, three fluorine ethane (F112), two chlorine, two fluorine methane (F12) and so on. By using the curing heat of the epoxy resin, the liquid with low boiling point is evaporated, and the gas is released, and the products are small in density and low in thermal conductivity. But fluorine hydrocarbons have a damaging effect on the atmosphere and are often used to spray foaming processes. According to the experts of China epoxy resin industry association, toluene and so on can be used as auxiliary foaming agent. In addition to foaming, it also acts as a curing reaction, a heat absorber and a diluent.

Q: What are the concepts, classifications and distinctions of modified plastics and plastic materials?: Plastic raw material:Concept: the word "plastic" in the word "plastic material" is intended as a material or plastic material that can be arbitrarily shaped into various shapes. In the dictionary is defined as "synthetic or natural polymers as the main component, under certain conditions can plasticization and molding can keep shape, the end product of materials.Classification: (1) according to the characteristics of resin when heating and cooling, classification: 1. Thermosetting plastics, two, thermoplastics(2) according to the classification of plastic use: general plastics, engineering plastics, plastic raw materials

Q: What is the plastic basin made of?: The raw material is PP and PE, the raw material price is more than 10000, and some can be recycled at around 5000.

Q: Plastic raw materials, electroplating grade round face, electroplating grade, what is the concept?: The so-called plastic raw material electroplating grade means that the particle of the plastic material is high in purity and high in polarity, and is easy to be evenly adhered to the metal particles before the plating.

Q: What kind of material is the plastic bag commonly used in supermarkets now?: Another is PP or OPP, which contains bread and crackers. The material is smooth and very transparent, but the tightness is not very good and there is no tension.

Q: What material is plastic bag made of?: Polyethylene (Polyethylene, PE), referred to as PE. It is a high molecular organic compound which is made up of ethylene. Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flowers" laudatory title. It is the most important and most important material in plastic packaging and printing.

Q: What is the ash content of PP plastic raw materials?: If the PP plastics added talc, glass fiber, mineral fiber and other inorganic additives, there will be ash, the specific ingredients and quantity depends on what is added to it

Q: How to make plastic raw materials?: Cracking is in the process of petrochemical production, which is higher than the cracking temperature (700 DEG to 800 DEG C, sometimes even more than 1000 degrees Celsius), making oil fractionation products (including petroleum gas) long chain hydrocarbon in the fracture process into short chain hydrocarbons such as ethylene and propylene.Cracking is a much deeper cracking. The chemical process of oil cracking is more complex, generated by pyrolysis gas is a mixture of complex components, in addition to the main products of ethylene, and propylene, isobutene and methane, ethane, butane, acetylene, hydrogen sulfide and carbon oxides. After the pyrolysis gas is purified and separated, the basic organic chemical materials such as ethylene and propylene can be obtained with the required purity. At present, petroleum cracking has become the main method of producing ethylene.

Q: What are the raw materials for vest plastic bags?: Polyvinyl chloride, referred to as PVC, and the formula is (CH2 - CH2) n, is the most important kind of vinyl polymer, is the world's second largest plastic varieties after polyethylene. In China, the yield is the first in plastics. In the printing industry, packaging production of books, folders, tickets and other frequently used PVC calendered film cover color and transparent glazing film.

Q: What are the plastic raw materials for this purpose?: Plastic classification, composition and characteristics, plastic is a widely used synthetic polymer materials, in our daily life, plastic products abound.
