Q:What plastic material is used for plastic hose?: ABS pipe: good corrosion resistance, light weight, heat resistance is higher than PE, PVC, but the price is more expensive. Bonding, flange thread connection, sanitary ware sewer pipe, gas pipe, sewage pipe, underground cable pipe, high anti-corrosion industrial pipe, etc.

Q:How many kinds of plastic raw materials are there? How to distinguish them?: According to the nature of the plastic after heating, it is divided into thermoplastic and thermosetting plasticsThermoplastic molecular structures are linear structure, softening or melting when heated, plastic into certain shape, after cooling and hardening. When heated to a certain extent to soften after cooling and harden, this process can be repeated several times. Such as polyvinyl chloride, polyethylene, polystyrene and other thermoplastic. Plastic molding process is relatively simple, can continuous production, and has very high mechanical strength, so it is developing very quickly.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 become soft and will not change shape. The thermosetting plastic processing molding after heating no softening, and therefore can not be recovered then, such as phenolic, amino plastics, resin and other plastic. These are thermosetting plastic molding process is more complex, so the continuous production is difficult, but its good heat resistance, not easy to deformation, and the price is relatively low.

Q:I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!: Plastic generally does not contain benzene, ah, only polystyrene, ABS and other plastic molecular structure containing benzene ring, is a high polymer. Benzene is an organic solvent, low molecular substances, boiling point is low, very volatile.

Q:How many types of plastic materials are there?: Plastic classification, composition and characteristics, plastic is a widely used synthetic polymer materials, in our daily life, plastic products abound. We wake up from the use of toiletries, the breakfast dishes, to work with the rest of the stationery, with cushions, mattresses, and TV, washing machine, computer shell, and night gave us the light of the lamps in various shapes...... Plastics have gradually replaced many materials and utensils that have been used for decades and centuries with their excellent performance, becoming an indispensable assistant in people's life. Plastic, metal in hard wood, light transparent glass ceramics, corrosion resistance, rubber elasticity and toughness in a body, in addition to daily necessities, plastic more widely used in aerospace, medical equipment, petroleum chemical industry, machinery manufacturing, defense, construction and other industries.

Q:What is the plastic bag made of?: Method for identification of toxic plastic bags. The water detection method: put a plastic bag into the water, non-toxic can be surfaced, and poisonous won't rise; hand touch detection method: white or colorless transparent is non-toxic, the hand has a sense of lubrication, the surface like wax; color detection method: toxic haze or color yellow, red, black, feel sticky; jitter method: take a plastic bag shaking, crisp sound non-toxic; sound stuffy astringent toxic.

Q:How do plastic materials come from?: Polymer: any of the pure or polymeric materials produced by the polymerization process, whether natural or synthetic resins, are polymers, polymers, or polymers

Q:Main ingredients and formulations of PPR tubes: PPR pipe has energy saving, environmental protection, high strength, corrosion resistance, with smooth inner wall has the advantages of scale, construction and easy maintenance, long service life, widely used in building water supply and drainage, urban drainage, city gas, electric power and cable sheath, industrial fluid transportation, agricultural irrigation, industrial and municipal construction industry and the field of agriculture. The PP-R pipe is made of random copolymerized polypropylene and is extruded into tubes to be molded into tubes.

Q:Plastic PPT30S add what material will increase hardness?: In general, this material will be grafted with PP-G, POE, increase the impact, plus stone powder, glass fiber, mica powder, increase hardness.

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 plastic raw materials?: This polymer is made up of many smaller and simpler molecules made of covalent bonds. There are many kinds of polymers, one is to change the Prajna heat to classification, it can be divided into two categories.
