Advantages of PPR pipe
1. Maximum operating temperature can up to 95℃; it can work in a long term under the condition of 70℃ and 1.0Mpa.
2. PPR pipe density is only 1/8 of metal pipe; pressure resistance strength test is up 5Mpa, with good toughness, impact resistance.
3. Inner diameter of PPR pipe is little bigger than that of pipe fittings, which can ensure not to increase the resistance to fluid flow.
4. Inner wall of PPR pipe is smooth, no rust, no scaling, small fluid resistance
5. PPR pipe has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.
6. PPR pipe energy consumption is only 20% of steel pipe; its thermal coefficient is also only 1/200 of steel pipe, reducing heat loss greatly.
7. PPR pipe is poor electrical conductor material, which can avoid galvanic corrosion phenomena.
8. With poor thermal conductivity, PPR pipe can reduce condensation.
9. PPR pipes, fittings are recyclable.

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:If my bed is over the a/c vent, is there some plastic tube thing I can use to route the a/c air?
Move the bed. It's usually easier to do that than deal with a blocked diffuser. Or, since a small window A/C is so cheap nowadays, block the vent and put a window unit in that room.........
Q:I'm looking for the 12, 16, and 20 plastic flat bottom tubes w/ lids that you see used to make Sandy Candy.?
OKorder might have them. If not, find a candy supply company.
Q:Porous plastic couplings for the weak monitoring system in what the quota items?
Calculate the engineering quantity, according to the distinction between construction methods and technology, can find the corresponding item in the quota, get the corresponding price, multiplied by the calculated quantities, finally obtains the total price. This process is called "set quota"".
Q:What is the name of the plastic tube..
You can use either of the following : 1. A syringe. Usually the dentists give you a syringe without a needle. The one that is commonly given out is the monoject syringe that has the tip built into it with a slight curve. That means it is a one piece plastic syringe with the dispensing tip and a plunger. 2. You can also use a WaterPik or Water Jet Hope this helped :)
Q:The temperature in the plastic pipe is several times as bad as that of the plastic pipe
In fact, the two diodes are connected together by head and head, using the resistance increasing principle of the PN junction as the temperature increases.
Q:Is it normal to carry around little squares or tubes of plastic?
If okorder.com/... Now, if you can, try to stop this naturally if it is causing you disruption. Or at least try to contain it. That is how I would suggest you start to get a handle on this thing. Is it just trains you are obsessed with? or is it other things. Whatever you are obsessed with I would suggest NOT watching or viewing anything that stimulates this part of you to make you want to pick these things up or create them. If they happen to pop out at you, make a conscience effort to go the other direction when you feel that part of you being agitated. This is what you should do if you don't want to continue doing this. Now, as far as whether this behavior being normal or not... if it causes disfunction, or makes it so you can't be happy or live life to where you feel fulfilled, people would say that it is not normal. But to me, normal is just a setting on the washing machine. This is what makes you, YOU... Obsessive Compulsive (OCD) or not!!! :)
Q:Neon signs -- why are they not manufactured with plastic tubing instead of glass?
Maybe the gas reacts with plastic. Glass is non resistant to acids and corrosion.
Q:There are several kinds of domestic water pipes
Aluminum plastic pipe used to be a popular pipe in the market. Due to its light weight, durability and convenient construction, it is more suitable for use in home decoration. In the renovation concept of the new Guangdong and Shanghai, aluminum pipe has gradually no market, belongs to be eliminated products.Advantages: the price is cheaper, it can bend freely, the surface is smooth and convenient for construction.Disadvantages: easy aging, many hidden dangers and short service life. It is proved by practice that leakage is easy to occur at the pipe connection.
Q:Why is the concrete wall filled with long and thin white plastic pipes?
Mass concrete produces a lot of heat when it is solidified and must be released. Otherwise, it is easy to crack, so it is ventilated and cooled, but this possibility is the least. We usually use steel pipe.
Q:My dad on an oxygen machine 24/7, his cat is biting through the plastic tubing at all hours.?
Kill the cat before it kills your dad.
