Chemical Structure of PPR

PP random copolymer of ethylene molecules generally contain 1 7% (by weight) and 99-93% (by weight) of propylene molecules. On the polymer chain, ethylene molecules randomly inserted in the middle of the propylene molecules. In such a random or statistical copolymers, the majority (typically 75%) are single molecules of ethylene incorporated into the insert, called the X3 group (three consecutive ethylene [CH2] are sequentially arranged in the main {TodayHot} chain), which can also be seen as an ethylene molecule is inserted in the middle of two propylene molecules.

Another 25% of the ethylene molecule is inserted more incorporated into the main chain, also known as X5 groups, since there are five consecutive methylene groups (two ethylene molecules together two propylene molecules inserted in the middle). It is difficult to distinguish between X5 and higher groups such as X7, X9 and so on. In view of this, the XS and higher ethylene content groups together counted as> X3%.

Randomness ratio X3 / X5 can be measured. When the above percentage X3 group is large, it will significantly reduce the crystallinity of the copolymer, the final properties of this random copolymer influence. Ethylene copolymer has very high levels of crystallinity of the polymer, similar to the effect when high random polypropylene content.

Unlike random copolymer PP homopolymer as the polymer backbone randomly inserted into the ethylene molecules hindered crystalline arrangement of polymer molecules. Copolymers of a decreased change in crystallinity caused by physical properties: PP homopolymer and random copolymer is reduced in rigidity as compared to improve impact resistance, better transparency. Ethylene copolymers also lower melting temperature, which has become in some ways the advantages of their use.
Random copolymer may contain more leather extract and random PP, as well as a much higher ethylene content of the polymer chain. This higher leather extract content may, depending on the polymerization process, to varying degrees in all the goods copolymer materials and meet the Federal Food Administration (FDA) on food contact {HotTag} specified on the cause difficult.

Manufacturing method of PPR pipes:

Ethylene / propylene random copolymer and ethylene molecules is carried out by polymerization of propylene molecules simultaneously obtained, the use of the reactor and the production of PP homopolymer same. Ethylene propylene molecular ratio of small molecules is faster than the reaction (reactive approximately ten times) propylene. This stereospecificity of the catalyst activity is increased and decreased, resulting in increased generation amount of atactic polypropylene. In order to reduce the generation of such random thereof, the reaction temperature needs to be reduced, thereby reducing the activity of the catalyst, and to reduce the content of the final product ppr sizes random isomer, to obtain a product having a more balanced performance.

Ethylene content (> 3%) random copolymer in the production process more difficult to deal with, it is difficult to carry out polymerization in hexane diluent, since the two by-products of the reaction (the amount of atactic polypropylene and ethylene-containing high copolymer) can be dissolved in hexane. This bulk liquid propylene polymerization reaction is the same, in spite of low solubility. Diluted with hexane to produce a large number of process by-product, it must be separated out in hexane in the recycle phase, which will increase the total cost of production, but was able to get close sparingly soluble polymer component of the cleaner. In the bulk polymerization process, these impurities will remain in the polymer, and trouble in handling sheet-like material. Moreover, the final copolymer products contain more soluble impurities. Second washing with an organic solvent, most of the impurities can be removed, but will increase the overall cost of production of the copolymer. In general, a high content of by-products, the flake random copolymer will become more viscous, when the ethylene content higher than 3.5% (by weight), the problem is more prominent.

Q:How is 20 silver dollars inserted into plastic tube?
Home All Categories Computers Internet Internet YouTube ??
Q:How do I connect the cast iron sewer line with the PVC pipe?
With expansion joint, or quick joint, the expansion joint is cheaper and faster. In any plumbing shop there is a retractable knot. Will need to replace the cast iron pipes sawed off, the new PVC tube into the cast iron pipe of about 100mm, with the PVC pipe fixing clamp. Then in the gap between the PVC pipe and the cast iron pipe, the cement mortar can be used for grinding. When connecting, the outer wall of the cast iron pipe can be polished with gauze to prevent leakage.
Q:About plastic drain pipe expansion joint
The setting of the expansion joint of the plastic drain pipe is generally determined according to the requirements of the design document or the type of pipe, the mode of joint and the position of the environment.
Q:has anyone had the die test done to check your tube? if so please share you story?
Yes, and I don't want to scare you, but for me, it really really hurt. First they use a larger than normal speculum to hold your vagina open so they can see what they're doing. Then they use a swab with iodine to sterilize the cervix. Then they insert a long handled hemostat to pinch the edge of your uterus to hold it still so they can put the little tube in there. Then comes the super ouchy part, where they thread a little plastic tube into the cervix. I have heard some women say it was no big deal, and some say it didn't even hurt, but for me, it was horrible. Like a bad PMS cramp times a million. Like someone stabbed me in the uterus with a butcher knife. Then the little x-ray guy runs in, and pushes the dye through the tube, and looks at it in a monitor, which was pretty neat, bc I could see it on the monitor, and that kind of stuff fascinates me. Then the x-ray guy runs out, and my gyne pulled the whole fandangle out. He was going slowly, trying to be gentle, and I was like, I don't care! Just get this junk out of me!! But, on the bright side, the painful part lasted about 30 seconds. So don't stress too much. Even if you're one of the women for whom it will be painful, it is over very quickly. Good luck!
Q:When you drill a hole, and put a circulatar piece of plastic with a little tube that fits into it...?
wall anchor -- they also have metal ones for mason or brick walls ..... If you are hanging things from the walls, look into those new wall hooks from 3M that paste to the wall and you can peel it off so that you do not damage the wall.
Q:What's the meaning of the laying of brick and concrete structures with concealed pipes?
Line pipe laying:The wires are laid in bricks or concrete. There are two ways:Insert the wire tube and the bottom box before pouring;After the end of the masonry, slotted into the wire pipe and the bottom box, and then fill the groove.
Q:What about plastic pipe leaking?
The solution Water Leakage sewer pipe: 1, if it is PVC water, will be able to buy a PVC pipe to take, put the tube cut broken, the first set of interface end into the pipe, the other end of the cut position coincides with a hole in the interface Qi Ping, just to make it straight, and then directly to the end of delivery, the two ends have a certain distance (length) and then cross the water removed, with lateral water pipes and the two in the PVC at both ends of the inner side direct glue. 2, you can buy waterproof tape to repair the water pipe, it is entangled with the line, and then mortar, waterproof agent and cement on it. 3, looking for a professional company is a little better, if you can not handle it.
Q:What sensors can be used to measure changes in the water level in a transparent plastic pipe?
A magnet can be considered to be wrapped with foam plastic to float on the surface of the water. It is placed inside the transparent plastic tube, and a magnetic reed switch is used outside the plastic tube to induce the magnetic field switch.
Q:how do i safely clean the inside of used fluorescent tubes in order to use them for a different purpose.?
Don't do this. The glass is fragile and easily shattered. It contains mercury - not nice stuff to deal with. Get glass tubing or plastic tubing instead.
Q:Can I use a plastic tube instead of a gas pipe?
HDPE high density polyethylene plastic, English name is "High Density Polyethylene", referred to as "HDPE"". HDPE is a thermoplastic resin of high crystallinity and non polarity. The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals. Certain kinds of chemicals produce chemical corrosion, such as caustic oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer does not absorb moisture and has a good water vapor resistance and can be used for packaging purposes. HDPE has good electrical properties, especially insulation, dielectric strength, so that it is suitable for wire and cable. Medium to high molecular weight, with excellent impact resistance, at room temperature, even at -40F low temperatures.
