159. What are the characteristics of polyvinyl chloride (PVC)?

Answer: PVC, abbreviation PVC, is a white, non-toxic, odorless, amorphous powder with a density of 1.35 to 1.46 and no significant melting point. Non-flammable, insoluble in water, alcohol, gasoline, etc., soluble in tetrahydrofuran, methyl ethyl ketone and acetone and carbon disulfide mixture solvent. It swells in aromatics, chlorinated hydrocarbons, and some solvents such as ethers and ketones, and is stable to acids, bases, and salts at room temperature. However, the thermal stability is poor. The hard product starts to soften at 60-80°C, has plasticity at 120-150°C, and releases HCI gas when heated for a long time. The polyvinyl chloride resin can not be crystallized and assumes an amorphous form, and has a wide range of flow temperatures, that is, a wide temperature range from the thermoelastic to the thermoplastic state is 160 to 180°C. Various PVC products are easy to screen printing.

160. What are the weaknesses of PVC?

Answer: PVC's weaknesses generally include two aspects. On the one hand, it means that polyvinyl chloride resin has certain toxicity, because vinyl chloride resin remains in the polyvinyl chloride resin and it is a harmful substance. For PVC used in food packaging, the general international regulations stipulate that the residual amount of vinyl chloride monomer is less than 1ppm for safe non-toxic products; and the additives used for food packaging PVC should also be non-toxic; on the other hand, it is thermally stable. Poor quality, easy to cause heat decomposition to varying degrees of decomposition; soft products also make plasticizers out of the lack of deformation can not be fully restored, and will become hard at low temperatures.

161. What are the main characteristics of perchloroethylene (CPVC)?

A: The chemical name of chlorinated vinyl chloride is chlorinated polyvinyl chloride, an alias for vinyl chloride resin, abbreviated as CPVC. It is a white or slightly light-colored powder or loose fine particles, odorless, odorless, non-toxic, non-flammable, thermoplastic. , The maximum continuous use temperature is up to 105°C, good solubility, can dissolve spinning (chlorin fiber), has good adhesive properties, can be used as a coating and adhesive, can be dissolved in chlorobenzene, acetone at room temperature Various solvents such as tetrachloroethane. The chlorine content of CPVC is 56.8%. As the chlorine content increases, the density increases, the tensile strength increases, the softening point increases, and the melt viscosity increases. When the chlorine content is 65%, the density is 1.52, and the chlorine content is 60%, the softening point is 80 to 90°C, and 68% is 130°C. CPVC is characterized by excellent heat resistance, aging resistance, and chemical resistance.

169. What is a polyamide resin?

A: Polyamide resin is a general term for linear thermoplastic resins with many repeating amide groups. It is mainly made up of dibasic acid and diamine or polycondensation of amino acid hydrocarbons. It is usually called nylon. When it is used for fiber, it is called nylon.

170. How to name a polyamide resin?

A: The nomenclature of the polyamide resin is determined by the number of carbon atoms in the diamine and dibasic acid. The polycondensate obtained from the reaction of hexamethylene diamine and sebacic acid is called nylon 610, and the former number 6 refers to the binary element. The number of carbon atoms in the amine, and the latter number 10 is the number of carbon atoms in the dibasic acid; if made from the self-assembly of amino acids, it is determined by the number of carbon atoms in the amino acid, such as 6 carbon atoms in caprolactam Therefore, the self-polymer is called nylon 6 or polycaproamide.

171. What are the characteristics and uses of polyamide resin?

A: Compared with other thermoplastics, polyamide has a narrow range of heat softening temperature and has a relatively distinct melting point. At the same time good alkali resistance, can withstand the corrosion of aromatic hydrocarbons. It also has the characteristics of wear resistance, heat resistance, cold resistance, drug resistance, solvent resistance, oil resistance, light weight, easy molding, excellent mechanical properties, non-toxicity, easy dyeing, and easy screen printing. The disadvantages are poor acid resistance, light resistance, and stain resistance, and its thermal expansion and absorption are large, which easily affects the dimensional accuracy.

Polyamide resins are mainly used in the fields of machinery, instrumentation and film packaging.

172. What is polyurethane (PU)? What are the main uses of polyurethane?

A: Polyesters containing multiple (-NH-CO2-) repeat groups in the main chain of the polymer are commonly referred to as polyurethanes, or polyurethanes for short, which are commonly referred to as PUs.

Polyurethanes are mainly used for the manufacture of foam plastics. They can also be used to make polyurethane elastomers, which are divided into soft and hard parts.
