Q:Can PE material be used as food grade plastic?
Plastic film PE the main consumption areas, because of its more and more used in consumption and transportation, the development of the relationship between demand and the overall economic situation is bigger, basically maintain a slightly higher than the national GDP growth, the growth momentum of stable existence of rigid demand. From the flexible packaging film production statistics, since 2006, the average increase rate of 13%, but also confirms the steady growth of plastic film. Another important consumption area of polyethylene is plastic pipe, and its output increases with the pace of urbanization in China, and the increase of municipal pipeline construction projects is increasing. In the next few years, the municipal water supply and drainage, gas pipelines, and urban underground power, communication, sheathing and pipelines will continue to be the focus of development in recent years.
Q:What is the concept of plastic raw materials for turnover containers?
Plastic turnover box, other features: 1) plastic turnover box outer dimension refers to the maximum size of the logistics box cover. 2) the plastic turnover box has no standard inner concave, and the case size is 18mm. 3) the carrying capacity of a plastic turnover box means that the load is uniformly placed within the range of the environmental temperature. 4) the effective working temperature of the plastic turnover box is -25 DEG C - 40 DEG C. 5) plastic turnover boxes can be stacked for storage, saving space.
Q:How about the price of plastic raw materials now?
The downstream continues to be on demand, with little change in demand. There is a more detailed analysis of quotations
Q:What are the POE plastic raw materials?
Poe plastic raw materials are polymers of ethylene and butene, polymers of ethylene and isobutene.
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 raw material for producing corn starch plastic film?
It is corn starch raw materials of corn plant starch is a natural polysaccharide polymer, the molecular weight of up to 3 million Dalton, is a common concern at home and abroad can be used as the ideal material for the direct application of the polymer materials. Plant starch is divided into grain starch (corn starch, sorghum starch, wheat starch, rice starch) and potato starch (tapioca starch, potato starch, konjac starch).
Q:What raw material produces the plastic to the human body not to harm, to the environment does not have the pollution?
For example, light degradable plastics manufacturing methods can be divided into light degradable plastics synthetic degradable plastics and adding degradable plastics. A, ethylene copolymer / carbon monoxide (E/CO) photodegradation to ketone backbone fracture characteristics of.E/CO light degradation speed and degree and the amount of the chain, the higher the content, the degradation rate of the soon, the greater. The United States of Texas, scientists have to E/CO for outdoor exposure experiments in sunny June, the fastest E/CO only a few days can be degraded. B, ethylene / vinyl ketone copolymer (Ecolyte) keto Ecolyte molecules on the side chain can be decomposed to.Ecolyte light the degradation performance is better than E/CO in the role of natural light, but the cost is higher. This kind of polymer drawback is once see the light starts to degrade, almost no induction period, need adding antioxidants to regulate the induction period Purpose. (2) add type light degradable plastics additive light degradable plastics with a small amount of photosensitizer in the polymer, at low concentration is the degradation of photocatalytic oxidation by solar irradiation (Zi Waiguang) and react to the polyolefin polymer fracture. In PE, PP polymers such as ketones, amines and adding photosensitizer can good photodegradability. Add light degradable plastics with low cost, simple production process, do mulching better. But the degradation characteristics of the exposure surface degradation more thoroughly, some less degradation buried in the soil. The degradation of this kind of photodegradable plastics can be controlled in the induction period of two months or more. But the degradation time control is poor.
Q:How do you increase the transparency and hardness of PP plastic suction pipes? What raw materials do you need to add?
Add transparent nucleating agents to improve transparency, such as milk tea cups
Q:What are the plastic raw materials?
Plastic raw material is a kind of polymer (polymer), also known as macromolecule or macromolecule, also is commonly known as plastic or resin. The so-called plastic raw material, in fact, it is a kind of [synthetic resin], the shape of the natural resin [pine resin] similar, but because of the chemical strength of the synthesis, and is called plastic.
Q:Chemical, plastic raw materials, plastic raw materials how sub grade?
That's because the raw material used for making plastic barrels is different. Just like the quality of the clothes, the grades of the fabrics used are different, and the products presented are definitely different.
