Q:What is the difference between PP raw material and modified PP?: Sort:(1) according to the characteristics of resin when heating and cooling, classification: 1. Thermosetting plastics, two, thermoplastics(2) according to the use of plastics classification: general plastic, engineering plastics, special plastic raw materialsModified PPThe concept of modified plastic PP, 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: PP modified plastic products are mainly a variety of flame retardant resins, toughening resin, plastic alloy, functional masterbatch etc..

Q:What are the concepts, classifications and distinctions of modified plastics and plastic materials?: Modified plastics should, in principle, be made from the plastic raw materials produced by petrochemical plants. By adding plastic additives, they can enhance their hardness, fire resistance, high temperature or low temperature, weather resistance and ultraviolet resistance. Therefore, modified plastics are processed from plastic raw materials, which is the relationship between source and flow.

Q:What are the raw materials of foam plastics and how do they come out?: Chemical blowing agents are mainly azo organic compounds such as azo two formamide (ADCA or AC), 2, 2 '- azo two, DAB, AIBN, etc.. This kind of foaming agent is cheap, and the products are non-toxic, odorless and colorless. In addition to sulfonylhydrazine, such as 4, 4 '- oxo benzene sulfonyl hydrazide (OBSH) etc.. Attention should be paid to the decomposition temperature. The properties of chemical foaming agents are as follows:Azo two formamide (AC, ADCA). Orange crystalline powder. A large amount of gas (N2, CO and a small amount of CO2) is decomposed at 120 DEG C, and the gas yield is 200 ~ 300mL/g in the standard state, which is an efficient foaming agent.

Q:How many types of plastic materials are there?: There are many kinds of plastics. So far, there are about more than 300 kinds of plastic produced in the world. Many classification methods of plastic, there are two kinds of commonly used: 1, according to the nature of the heated plastic divided into thermoplastic and thermoset plastic molecular structure are linear structure, softening or melting when heated, plastic into certain shape, after cooling and harden. After heating to a certain extent, it softens again and hardens again after cooling. This process can be repeated many times. Such as PVC, polyethylene, polystyrene and so on. Thermoplastic molding process is relatively simple, can be continuous production, and has a high mechanical strength, so the development of very fast. The molecular structure of thermosetting plastics is the body structure, softening also occurs in heated, can plastic into a certain shape, but is heated to a certain extent or amount of curing agent, hardened stereotypes, re heating will not soften and change the shape of the. Thermosetting plastic processing, molding, the heat is no longer softening, and therefore can not be recycled, such as phenolic plastics, amino plastics, epoxy resin, etc. belong to this kind of plastic. Thermosetting plastic forming process is more complex, so continuous production has some difficulties, but its good heat resistance, not easy to deformation, and the price is relatively low.

Q:Characteristics of rigid polyurethane foam made of polyurethane raw material: Rigid polyurethane foam in the developed countries, building hard polyurethane hard foam accounted for the total consumption of about 70%, is a refrigerator, freezers and other hard foam dosage more than doubled; in China, application of rigid foam in construction industry is still not as common in western developed countries, so the development potential is very big.

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: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 are the raw materials of plastics made of?: The plastic is made of natural or synthetic resin as the main ingredient, adding various additives, in certain conditions such as temperature and pressure can be made into a certain shape, keep shape materials at room temperature.

Q:What's the shell of the relay? What exactly is plastic?: Relays, usually thermosetting plastics, refer to plastics that can be cured or otherwise insoluble in heat or other conditions, such as phenolics, epoxy plastics, etc.. Thermosetting plastics can be divided into two types: formaldehyde, cross-linking and other cross-linking. Formaldehyde crosslinked plastics include phenolic plastics and amino plastics (such as urea formaldehyde melamine formaldehyde etc.). Other crosslinked plastics include unsaturated polyester, epoxy resin, phthalic two, diallyl resin, etc..

Q:I do PA, PC, PP and other plastic raw materials can be used in the eye frame and lens it: In general, the lenses of PC need to be covered with scratch resistant protective films, which will be sufficient for better aging, and most lenses for children.
