Material properties of PPR
PPR Physical properties: generally, the flexibility of the ratio of random PP copolymer is better than that of PP homopolymer, and the rigidity of them are in contrast. When the temperature dropped to 32 ° F, they can maintain moderate impact strength, and when the temperature dropped to -4 ° F, the usefulness will be limited. Flexural modulus (1% secant modulus of strain) of the copolymer is in the range of 483 ~ 1034MPa, and the homopolymer in the range of 1034 ~ 1379MPa. Effect of molecular weight PP copolymer material is not as rigid PP homopolymer large. Izod notched impact strength is generally in the 0.8 to 1.4 foot-pounds / inch.
PPR Chemical properties: PP random copolymer acid. Alkalis, alcohols, low-boiling hydrocarbon solvents and many organic chemicals have a strong resistance. At room temperature, PP copolymers are essentially insoluble in most organic solvents. Moreover, when exposed to soap, lye soap. Aqueous reagent and alcohols, they do not like many other polymers that would occur environmental stress cracking damage. When in contact with certain chemicals, especially liquid hydrocarbons, Chlorinated organic and strong oxidizing agents, can cause surface cracks or swelling. Non-polar compounds are generally easier than the polar compounds absorbed polypropylene. The molecule only carbon, hydrogen, no harmful toxic elements exist.
PPR Barrier properties: PP homopolymer and copolymers have a very low water vapor permeability (0.5 g / cc / 100 square inches / 24 hours). These properties can be improved by orientation. Stretch blow molded polypropylene bottles Yiba resistance to water vapor permeation performance improvement to 0.3, the oxygen permeability of 2500.
PPR Electrical properties: Generally, polypropylene has good electrical properties, including: high dielectric strength, low dielectric constant and low dissipation factor; however, power applications usually selected homopolymer.
PP-R pipe production process is extrusion process, first add PP-R raw material in the hopper by gravity into the extruder in the extruder barrel heated extrusion mixed and fully plasticized from the extruder mouth die extruded into stereotypes, stereotypes of the pipe after by tractor, measured by length, cut by the cutting machine, after passing the test tube after storage. Corresponding pp-r pipes and fittings are produced by injection molding.
Polyethylene pipe production process: PP-R raw materials → vacuum suction hopper send feed storage → extrusion → cooling stereotypes traction → cutting → inspection → warehousing pipe production process: PP-R materials → feeding conveyor → storage hopper feed heating and melting → cooling and molding injection extrusion mold → inspection → warehousing.
Pipe Extrusion parameters: (1) a screw speed of 5 ~ 38r / min (2) barrel temperature profile of 1 to Zone 2 180 ~ 190 ℃ 3 ~ 4 region 200 ~ 210 ℃ mold temperature of 200 ℃ traction speed 2 ~ 20m / min Tube injection parameters: 200 ~ 230 ℃ front barrel portion (1) cylinder barrel temperature profile 160 ~ 170 ℃ rear central cylinder 180 ~ 200 ℃ (2) of the nozzle 170 ~ 190 ℃ (3) 40 ~ 80 ℃ PP molds -R pipe production process defective products, after crushing can be used again, which improves utilization of raw materials, and reduce production costs, improve economic efficiency.
- Q:It is the small piece that stops the tube spring from coming out of the tube when the last round is pumped out.???
- its okorder /...
- Q:I have a little bit of a project. I'm trying to figure a way to cool a pair of water filled tubing lines. I was thinking to wrap it with some type of cooling device but not quite sure what to use. Can you guys give me some ideas? I want to cool the lines as cool as refrigerator temps. Thanks.
- You have not said how much heat you need to disperse - whether it needs to be a continuous process or not. You have not mentioned whether the lines are flexible or what length they are! However, without making things too complicated, if you use a longish length of plastic tubing, you could coil them and run them through a bucket full of an ice/salt/water mixture. Depending on how fast the water is moving through the tubes, if you had a strong mixture of salt and ice - with just enough water in the bucket to allow conduction - you might be able to freeze the water in the tubes - which is probably NOT what you want to do. So experiment before the performance.
- Q:How do plastic tubes compare to cardboard tubes in terms of strength?
- Plastic tubes generally tend to be stronger than cardboard tubes in terms of strength. Plastic tubes are more durable and resistant to bending or crushing compared to cardboard tubes, which can easily collapse under pressure. Additionally, plastic tubes are often able to withstand harsher environmental conditions, making them more suitable for applications that require higher strength and durability.
- Q:What are the different closure options for plastic tubes?
- Some of the different closure options for plastic tubes include screw caps, flip-top caps, snap-on caps, squeeze caps, and pump dispensers.
- Q:Pretty much anything safe a flexible that can be used. Needs to be about 3 or 3.5 inches in diameter. I need quite a bit of it. You know the play places at McDonalds for kids? Well, thats basically what I'm going to do only much smaller for my two ferrets. Can anyone point me in the right direction to find what I'm looking for? I'd like to find something other than PVC unless I can find about 20 feet of it that's flexible, clear, 3.5 inches diameter, and without an outragous price. Thanks so much.
- Why not stop by your local department stores gift wrapping department and ask them for their left-over tubes? (The tubes they have are the ones inside their roles of wrapping paper which are the perfect size for ferrets...I know, I have some myself. hehe) You will sort of look like an idiot asking the employees for them but what the heck!! Put on your best smile and ask. They are free AND they were just going to throw them out anyway. And if this makes you feel better, I used to work at a department store when I was much younger and people would ALWAYS come in and ask for empty boxes and cardboard. Its fairly common. ;)
- Q:I own a 1995 Toyota Celica. A plastic tube next to the aluminum tube eventually rubbed a hole. Can this aluminum tube be repaired, or do I have to replace the entire thing?
- I doubt it. If it's an AC line it has to be replaced. Aluminum is difficult to weld,
- Q:What is a socket connection?
- The spigot and socket connection is mainly used for cast iron pipes, concrete pipes, ceramic pipes and plastic pipes with spigot and socket joints.The socket connection interface mainly includes: green lead interface, asbestos cement interface, expansion filler interface, apron interface, etc..
- Q:Can plastic tubes be used for architectural installations?
- Yes, plastic tubes can be used for architectural installations. They are often used for temporary structures, such as exhibition displays or event installations. Plastic tubes offer flexibility in design, are lightweight, and can be easily shaped and manipulated to create unique architectural features. Additionally, they can be transparent or colored, allowing for creative lighting effects. However, it is important to consider the specific requirements of the installation and the durability of the plastic material to ensure it meets safety standards and can withstand environmental conditions.
- Q:Do plastic tubes have any limitations in terms of compatibility with other packaging materials?
- Yes, plastic tubes do have limitations in terms of compatibility with other packaging materials. Some plastics may not be compatible with certain chemicals or substances, leading to potential reactions or degradation of the packaging material. Additionally, plastic tubes may not be suitable for certain packaging methods or applications, such as those requiring high temperatures or pressure. It is important to consider the specific requirements and properties of the packaging material and its compatibility with other materials to ensure an effective and safe packaging solution.
- Q:What does "DN" and "Dn" mean in plastic pipes? And de?
- DN, Dn said the method is wrong, the correct representation should be DN, on behalf of the nominal diameter; de represents the outer diameter of the pipe (PVC pipe, PE pipe is generally PPR or other non - metal pipe).
