Q:What is the difference between PPA plastic raw material and PP?
Two kinds of materials are two grades, figuratively speaking, PPA is Benz, PP is alto.
Q:What type of raw material for plastic straw?
The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role. Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene. The so-called plastic, in fact, it is a kind of synthetic resin, the shape of the natural resin with pine resin similar to, through chemical means of artificial synthesis, and is called plastic.
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:Dissolve in 0.3 of the LDPE plastic raw materials what?
The molecular structure of the conventional LLDPE is characterized by its linear backbone, with only a few or no long branched chains, but contains some short branched chains. Without long branched chains, the crystallinity of polymers is higher.In general, LLDPE resins are characterized by density and melt index. The density is determined by the concentration of comonomer in the polymer chain. The comonomer concentration determines the short branch chain in the polymer. The length of the short branched chain depends on the type of comonomer. The higher the concentration of comonomer, the lower the density of the resin. In addition, the melt index is a reflection of the average molecular weight of the resin, mainly determined by the reaction temperature (solution method) and the addition of chain transfer agents (gas phase method). The average molecular weight is independent of the molecular weight distribution, and the latter is mainly influenced by the type of catalyst.
Q:What kinds of plastic properties can be divided into thermal properties?
A. thermoplastic(a) polyvinyl chloride (PVC)Is the most widely used plastic varieties. Polyvinyl chloride resin is made from poly (vinyl chloride) monomer. According to the amount of plasticizer, it is divided into hard PVC and soft PVC. The former adds 30~70 phr of plasticizer <5 in 100 heavy resins, and the latter adds plasticizers.Physical properties: the relative density of hard PVC is 1.35 to 1.60, which is 1 / 5 of carbon steel; the relative density of soft PVC is 1.2 ~ 1.4.The water absorption rate of hard PVC is very low. The water absorption rate in long-term immersion in water is <0.5%; the soaking water is 24h, and the water absorption is 0.05%. The permeability of PVC is very low.The glass state temperature of PVC is 80~85 DEG C, the viscosity is 180 DEG C, the decomposition temperature is 240~260 DEG C (including stabilizer), and the brittleness temperature is -50 ~ -60 DEG C.The recommended temperature range of hard PVC is, in principle, maintained in terms of brittleness and glass temperature. If it is used above 50 degrees, necessary measures should be taken.The pure PVC, without stabilizers, begins to decompose at 150 C, releases hydrogen chloride, and further accelerates its decomposition. It decomposes faster than 180 DEG C. The polyvinyl chloride with the stabilizer decomposes the temperature to 240~260 degrees centigrade, but breaks down hydrogen chloride if used for 220 years. The material changes from dark grey to yellow brown, or even black. Therefore, in welding, we should try to avoid this phenomenon, the linear expansion coefficient of hard polyvinyl chloride is (5~6) X10-5 / DEG, 5-6 times larger than carbon steel. Therefore, when installing polyvinyl chloride pipes, expansion joints or bracing shall be installed to prevent deformation. When polyvinyl chloride is used as lining or bonding with other materials, the peeling phenomenon may be considered when heated.
Q:Commonly used plastic products, which are made of what raw materials, which can be recycled, I hope to get a professional answer in detail
Plastics are classified into thermoplastic and thermosetting plastics according to their plasticity. Normally, thermoplastic products can be recycled, while thermosets do not. According to the optical properties of plastics to points, can be divided into transparent, translucent and opaque materials, such as PS (polystyrene), PMMA (polymethyl methacrylate, PMMA), AS (styrene acrylonitrile copolymer) and PC (polycarbonate) belong to the transparent plastic, and it is the most opaque plastic plastic. There are many ways to classify plastics. They are no longer introduced.
Q:What are plastic materials extracted from?
All kinds of plastics are gradually processed to produce various kinds of downstream products, including rubber, coating, finishing agent, artificial fiber, synthetic resin and so on.Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer.
Q:What are the main biodegradable plastic bags made of?
Biodegradable plastics(1) natural polymer modification method. Starch, cellulose, chitin, lignin, seaweed and other natural polymers as raw materials, through chemical modification and copolymerization method, these molecules were modified to synthesize biodegradable plastics.(2) chemical synthesis. The simulation of natural polymer structure, starting from simple water molecules, in the polymer chain of plastic with active groups such as amide, peptidyl, ester compounds containing these radicals, similar to natural protein structure, fragments of grease, easily biodegradable.(3) microbial fermentation, many microorganisms can take some organic substances as carbon source, through metabolism, secrete, produce polyester polymer, these molecules are easy to degrade, and can be further recycled.
Q:How do plastic raw materials trade? How big is the market?
Traditional trading model is to realize the circulation of plastic raw materials with contacts, telephones and fixed customers. The Internet trading mode of transaction is transferred from the line to line, from order flow to terminal distribution capabilities are strong, with IT technology and services to provide information, plastic raw materials trading, a full range of logistics finance.
Q:What is Ms plastic material?
Transparent polymers were synthesized from methyl methacrylate (MMA) and styrene (SM) as the main raw materials.
