HIPS resin absorbs water slowly, so there is no need for drying in general. Sometimes excessive moisture on the surface of the material will be absorbed, which affects the appearance quality of the final product. Under the temperature of 160 F dry 23h can remove excess moisture. The extrusion of thin films, sheets and profiles is the most useful processing method for HIPS. Anti impact polystyrene has a wide range of processing, so it becomes one of the most easily thermoforming resins. Generally, the melting temperature of the resin is 400 - 500 F, and the melt index range of the resin is 1.5 - 4 g/10min. Rotating, series and shuttle type pressure and vacuum thermoforming equipment are often used. HIPS has excellent thermal stability and shear stability. It can be used for a lot of recycled materials without reducing the performance of products, and the amount of recycled material in hot forming can be as high as 60%. Injection molding is the most used processing method next to the extrusion. The injection molding of the resin is usually carried out on a reciprocating screw injection molding machine with a length to diameter ratio of 16:1 to 24:1 and a compression ratio of 2.5/1 - 3.0/1. The processing temperature is 350 - 500 degree F, but for the flame retardant HIPS, the processing temperature must be less than 470 F to prevent the additive from producing degradation reaction. The melt index of the resin processed by injection molding is generally 5 to 15 g/min. The forming method of structural foam plastics is a common process, using chemical and physical foaming agents. Although a variety of HIPS resin are compatible with each other, but before the operation to clean processing equipment, to ensure good product quality, the impact of acrylonitrile with a PS Th ene styrene copolymer (ABS), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), acrylic resin and most other plastics are not compatible, incompatible plastic mixture separation will produce delamination phenomenon in processing equipment, caused great decline of physical properties. application Impact resistance PS is easily machinability, good performance and low price, so it is used to manufacture products and industrial products of many uses. The main applications are packaging and disposable supplies, instruments, household appliances, toys and entertainment supplies, and construction industries. The largest use of HIPS is to be used as a packaging and disposable material, especially for food packaging and eating tableware. The main applications include the daily packaging container. A cup, a variety of covers, plates, bowls, etc. are used and distributed for the vending machine. Disposable products such as disc, bottle cap, safety razor, pen and so on are also a part of the use of HIPS. PVC carcinogen, which will undoubtedly affect the development of PVC to some extent. However, the residual VCM has been successfully reduced by vehicle and other ways, so that the content of VCM in PVC resin will be less than 10ppm, which will meet the requirement of hygienic grade resin and expand the application scope of PVC. Even the content of VCM in the resin is less than 5ppm, and the residual VCM is very few after processing. It is basically harmless to the human body and can be used as food and medicine packaging and children's toys. Main classification According to the different application range, PVC can be divided into general PVC resin, high degree of polymerization PVC resin and crosslinked PVC resin. The general PVC resin by polymerization of vinyl chloride monomer is formed under the action of initiator; high degree of polymerization of PVC resin is resin in the polymerization of vinyl chloride monomer added to the system, the chain growth polymerization crosslinking agent; PVC resin is added to the resin crosslinking agent containing dienes and polyenes in vinyl chloride monomer polymerization polymerization system. According to the method to distinguish the vinyl chloride monomer, can be divided into electric stone, and imported ethylene (EDC, VCM) monomer method (on the habits of the ethylene monomer and import system called ethylene method). According to polymerization method, PVC can be divided into four main categories: suspension polyvinyl chloride, emulsion polymerization, polyvinyl chloride, bulk polymerization, polyvinyl chloride and solution polyvinyl chloride. Suspension polyvinyl chloride (PVC) is one of the most productive varieties, accounting for about 80% of the total output of PVC. Polyvinyl chloride suspension method is divided into six models according to absolute viscosity: XS-1, XS-2... XS-6; XJ-1, XJ-2... XJ-6. The meaning of each letter in the model: X- suspension; S- loose type; J- compact. method polyvinyl chloride PVC can be made by substitution reaction of ethylene, chlorine and catalyst. Because of its fire prevention heat effect of PVC is widely used in all walks of life every kind of products: wire skin, skin fiber, shoes, handbags, bags, accessories, signs and billboards, building decoration supplies, furniture, ornaments, rollers, pipes, toys (such as the famous Italy "Rody" jumping horse), curtain, door, auxiliary medical supplies, gloves, some food preservation paper, some fashion etc.. Polymerization method PVC was prepared by free radical addition polymerization. The polymerization methods were mainly divided into suspension polymerization, emulsion polymerization and bulk polymerization, mainly by suspension polymerization, which accounted for about 80% of the total output of PVC. The pure water, liquefied VCM monomer and dispersant were added to the reactor, then initiator and other auxiliaries were added. After heating to a certain temperature, the VCM monomer was polymerized by free radical to form PVC particles. Continuous stirring makes the particle size uniform and makes the generated particles suspended in the water. In addition, the PVC paste resin was produced by micro suspension, and the properties and paste properties of the products were all good. The monomer droplets are dispersed in the aqueous phase suspension polymerization method, using oil soluble initiator were dissolved in monomer, polymerization reaction in the droplet, the polymerization heat absorbed by the water in time, in order to ensure that these droplets in water were bead dispersed, need to join the suspension the stabilizer, such as gelatin and polyvinyl alcohol, methyl cellulose, hydroxyethyl cellulose, etc.. Most of the initiators are organic peroxide and azo compounds, such as peroxide two, two isopropyl carbonate, peroxide two, bicarbonate, peroxide two, two ethylhexyl ester, azo two isoheptane, azo two isobutadiene and so on. The polymerization is carried out in a polymerizer with a agitator. After polymerization, the monomer material flows into the recovery tank?or?stripper recycle monomer. Then into the mixing kettle, water washing then centrifuge dehydration, drying and resin finished products. The vinyl chloride monomer should be removed from the resin as much as possible. As the PVC for food packaging, the content of free monomer should be controlled below 1ppm. During polymerization, the temperature and pressure of the polymerization process must be controlled to ensure that the specified molecular weight and molecular weight distribution range are obtained and the detonation is prevented. The particle size and particle size distribution of the resin is controlled by the stirring speed and the selection and dosage of the suspension stabilizer. The quality of resin is characterized by particle size and particle size distribution, molecular weight and molecular weight distribution, apparent density, porosity, fisheye, thermostability, color, impurity content and free mobility of powder.
