Q: What are the concepts, classifications and distinctions of modified plastics and plastic materials?: Concept: modified plastics, refers to the base of the general plastics and engineering plastics, after filling, blending and enhancement processing method of modification, improve the performance of flame retardant plastic products, strength, impact resistance, toughness.Classification: modified plastic products are mainly a variety of flame retardant resins, toughening resin, plastic alloy, functional masterbatch etc..

Q: Pollution in the production of plastic raw materials from petroleum production: Manufacturing process of resin is the number of small molecular materials (high molecular compound monomer, alkane, olefin, could also have liquid such as gasoline and diesel decomposed) by polymerization together into a polymer compound. The polymerization can be divided into polymerization and polycondensation according to the composition of monomer and the change of result.The reaction of monomer addition and polymerization is called polymerization. Condensation polymerization is the process of reaction, in addition to forming high polymer, but also produce water, alcohol, ammonia and other low molecular by-products. The composition of the polymer is different from that of the raw monomer. After polymerization, the polymers with large molecular weight can be obtained. Synthetic resins are polymers of high molecular weight. Resins can be divided into two categories according to their properties after heating: one is called thermoplastic resin, and the other is thermosetting resin. Thermoplastic resin after heating can soften, flow, repeatedly plasticization and molding, such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyamide; thermosetting resin is soluble and fusible before processing, but in the heating, pressurizing and curing agent under the action can become insoluble and infusible, cannot be heated again softening products to curing, phenolic resin, urea formaldehyde resin, epoxy resin, unsaturated resin belongs to this kind of resin.

Q: What is the plastic basin made of?: Machines generally use injection molding machines, raw materials using PP and PE, the raw material price of more than 10000 a meal, and some can be used to feed prices at around 5000. Equipment price depends on your size, small injection molding machine plus two or three sets of film, about one hundred thousand on it.

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 are the POE plastic raw materials?: POE classification of plastics raw materials:Plasticizing properties: Thermoplastics and thermosetting plastics.Divided by use: General Plastics and engineering plastics.

Q: What is the material of plastic dip?: DIP processing, in general domestic PE dip powder or PVC dip plastic liquid. Specific depends on product characteristics and characteristics. Under normal circumstances, outdoor products, such as large pieces of metal products, PE dip plastic powder used for dipping plastic processing. PVC dipping liquid is more used for anti-skid products.

Q: How many kinds of raw materials are there for blowing plastic bottles?: Mainly used in beverages, food, pickles, honey, dried fruits, edible oil, agriculture, veterinary drugs and other liquid or solid disposable plastic packaging containers. Plastic bottles are not easy to break, low cost, high transparency, food grade raw materials and so on.

Q: What is the essential difference between plastic raw materials and engineering plastics?: Engineering plastics generally have many properties that are not common in plastics. They are often used in construction machinery to replace certain metals.Plastic is resin and filler, so it is usually granular. Raw materials too. Only a few powdery.

Q: What is Ms plastic material?: Copolymerization of styrene and methyl methacrylateMS resin is commonly used transparent plastic raw materials, general injection molding and extrusion molding, transparency of nearly PMMA, for optical components / toys / lampshades, lighting, /OA accessories / food containers / household appliances / building materials, etc.

Q: What two ingredients fit together to solidify like plastic?: If the viscosity of the epoxy resin is reduced, a curing agent with poor adhesion (e.g., I am a fast curing agent) is adopted. By vacuum and so on, let the glue into the gap, pay attention to the hardness of the curing agent should be higher, so as to effectively measure
