Use of polypropylene in the construction Qalpaq

Development of new technology in order to reduce cost, to avoid appearing to environmental problems, in conformity with safety standards is required and it seems necessary. The automotive industry exception not now Saipa to achieve this level of technology to try. One of the steps taken in this way, using material of polypropylene (PP) and the price is suitable for chemical and physical properties. The statistics obtained in recent years, the range can be developed following the use of polypropylene rise. Especially in parts production vehicles, including domestic and foreign parts with polypropylene face of this development is that parts can Qalpaq pointed. Face indicates that the statistical Korea in 2000 and have come.

  


Advantages of Polypropylene
Today, with development of applications of polypropylene can be said that Article substitute many ENGINEERING PLASTIC is. Low prices and Zrbhpzyry final product one of the major factors in the use of this material is Bhshmar.
Currently, vehicles, materials Qalpaq Plyamydy is made that this material is produced outside the country. Considering this and the production of polypropylene in the country, can the importance of the following range economic plan.

Disadvantages of using polypropylene
Disadvantages of polypropylene for use in different Qalpaqha can Shrynkyj with poor paint adhesion and Plyamyd been pointed piece blast.

Talc
In order to learn and correct fault and it can eliminate the effect of talc use Bszayy reform and improve the mechanical properties of materials input Shrynkyj piece will.
2 / 9 percent of global production talc, as the filling material used in plastic industries. Plastyksazy because of the shape, size, thermal resistance and Ductility Talc, which is used as filling material. This article in order to increase the mechanical strength and increase quality levels (reduced graze), is added to polypropylene Khzshy and heat resistance and it takes up. Ryvlvzhy also strengthen the melting Shrynkyj and reduces the construction of this property in polypropylene and polyethylene used (Khanhsazy, plastic furniture, automobile parts). Talc in the construction of special Plastykhay as Plastykhay thermal engineering (ETP) is used.

Modified paint adhesion
Another piece of the problems with polypropylene blast there, the paint adhesion is weak. In order to solve this problem, two ways are proposed:

First proposed solution
Modified use of polypropylene. This type of reaction between the polypropylene and polypropylene Malyyk Anhydride is the result. After hydrolysis, a carboxylic acid group appears in the main chain can be said that the main factors to improve paint adhesion property of this Article. For example, the urethane-based paints, paint Ayzvsyanat group Functional group reaction with the polypropylene is placed. 

 

  

Main advantages of this method, Lavhbr improve paint adhesion property polypropylene can remove primer (Median before final color piece is stricken state of primer) pointed. As you know, because in normal mode, the process of plastic paint can form displayed below. 

  
While this method is no primer.

The second proposed solution
Use of SMA as an add-on to polypropylene. Reaction between SMA and Malyyk Anhydride Styrene result depending on the amount of Styrene is used, the difference is Qtbyt. Bhtvry that can SMA2000, SMA1000, and SMA3000 ratio Anhydride Styrene Malyyk to a one, two and three to a range name. In fact Baafzvdn SMA, polypropylene Ghyrqtby the polar adhesion and thus create the color desired in the factor group, it goes up. 
 

  

The advantages of this method, Lavhbr improve paint adhesion property can be improved mechanical properties, high dispersion 1 Viscosity Reduction pointed.

Conclusion
With the problem and considering the advantages of polypropylene can be concluded that this material one of the best Antkhabhast. Therefore the production of polypropylene, which is reforming its property Rngpzyry can access Lavhbr Mrghvbtr product, rich in its economic benefit from the application domain and range using this material with the production of the country for use in the development and Qalpaqha As a result, a technology optimized for polypropylene Rngpzyry ability to create opportunity for both the producer and consumer benefit is a happy and useful Information.

Full engine power

Carl Ladvyksn writes: «the only topic that I regret writing this article is that I want an engine with so-called Fantastic commissioned more than what I deserve is introduced. But the respected news sites, before time and space for the motor to have recent exhibition for the first time in the car Lvsanjls has been visible to everyone.

 

 
This engine called «engine or engines capable MYT» and know something is Rafael Mvrgadv of Lady Njllbs company - Ltd. - Drkalyfrnya. Web address in the following states:
htt: / / www.angellabsllc.com/
Exclusive Mvrgadv said in an interview:
«You claim that this engine is Myshvyd flabbergasted. Claimed that 85 pieces of a common engine that is available. Said that the engine 848 cubic inch (o.o14m3) in volume 14 cubic inches (229cm3) weight of 150 pounds (68kg) have instead.
Useful power output of 850 Asbbkhar in normal mode and 3000 Asbbkhar is strongest. This engine also claim that a minimum amount of off gases and pollutants is the minimum fuel consumption and the production is simple.
We built this tool to re-equip the engine without the truth and join the concessionaire for the engine manufacturers for fast supply business is very appropriate.
Njllbs website states that:
«Hard work you designers and developers industry Mvtvrsazy was very disturbed because when you understand that the ability to build such a motor, have always, but have not understood it.
Slit with a huge share of the power plant, an industrial revolution and other figure sets Shlhhay internal combustion engine is transferred to the next millennium.
Does the lack of discovery and use of such a clear gap engineering are not ashamed? »
Mvrgadv, speed Auto racing competitions former driver says:
«Lbs Angell family is united and sincere. Experts that as a team to build my inventions, as the products meet the growth and progress, engaged to Men. Njlbs composed of inventors, scientists, engineers, business managers, Kamypvtr technicians, programmers, mechanical, engine specialists, lawyers and consultants, Business Owner of many. As Angell Lbs growth is, different teams will be able Bhfrd unique inventions and the many simultaneously, under my guidance and leadership, to expand.
Finally, our goal, and introduced many products in each chapter is a fundamental change. After this, you should search on how to achieve this miracle to be ».
Center (heart) MYT engine with a cylinder that is active for a full cycle is bent. This cycle, as is a surface coil. Pystvnhay way inside the ring circulation Drmyaynd Fshrdhand so that beds are similar to a page. This water is directed by the Central Ahrmhay. This engine, piston 8 Generally there are four of the Gangs, and categories have been categorized as the crusade format is installed.
This engine has a smart system, a mechanism is large and great detail. This mechanism allows the two groups in a quadruple helix during piston to move in during the same touch as that takes place between them and cause open space between the piston is closing.
Only around half of the spiral, each pair of piston diameter of the full four beats, which are included to draw air into and out of the Hungarian Khrvjyand gases.
MYT engine is not yet established. If this engine was down, could both its output axis 16 to produce the impact force.
This is a ghost and logical, but wrong in principle.
Size dead engine, the total difference between the maximum and minimum volume encapsulate it, the type MYT, 212 cubic inch or 5 / 3 is lit. The issue that this could be huge in size for packaging small place, much praise, but this amount is much less than the amount of claims 9 / 13 is lit.
Pendulum motion is important that communication with the motor output axis that is how, so we being to low or high volume of empty space to Nmydhym.
Axis output of a large number of motors, including a number of old engines and vehicles contesting the air for different reasons have been equipped with various devices.
Design is a Bhgvnhay MYT axis output is very slow work and the songs can be equally Svkhtrsany that solves problems, is Mshklsaz. As Msthzryd engines, however, spiral engines are not new. France «Dyvandr» One of these engines in the 1905 construction. Later in 1912 the same engine as the air industry Esselbe construction was revised.
At the time, effort, the other was a French engine Beck. Decade 1930 Design «John Padvn» cause piston used to control the snake cam was. Bhtvry late in the century that BSA motor for use in gas engines made.
Engineer «Lewis Wolff» Bzaska in Avmahay state, 30 in the decade that also produced motor winding and for vehicles used for aircraft, but he claims to create spiral aircraft engine manufacturing company, never.
After World War II to develop and improve the engines in two spiral Bhszayy efforts was conducted. One of these two cases, by military engineer with a history of profuse «Granvyl Bradshav» that this strategy was performed in the War, and how it was Astadanhay cause rotational movement of the piston to the spiral become.
Bradshav, two types of engine in 1100 and 1250 Sisian construction. The motors Bhtvr extensive publicity were 50 decades. Other efforts, design «Tragvt Shvdy» 60 decades that he Pystvnhay engine cam shaft and was taken forward. Despite the hope that productivity and profitability of these engines were basic (after Vnkl Internal combustion engines) but the Swiss engineer Failure in progress. Any of these engines has failed spiral density MYT engine power was not expected. Those Mvtvrhayy by professional engineers and technician were designed, the cooling system and had no clear strategy and to suggest «Mvrgadv» were. Engines Bbndy was a great competition MYT engine model could be successful, but no requirements for any Bbndy arms and pages, for the piston to knock the developers did not offer this industry. Although this will be very difficult.
Online Lbs Angell, were interested in contrast to the motor giant with the common and conventional power plants to show. In fact, the predicted specific power, is something very close to the engines currently «Formula One» is designed. The motors, more than 700 Asbbkhar force of volume equivalent to 4 / 2 liter 8 valve with 200 pounds of weight derive. This situation of what was said about MYT, not so far. All of the engines have a significant and high durability.
If MYT by step to build and run Mjz·hay acquire, Khnkknndh system and lack of lubrication system, the cause was Sramykhayy and hard alloys with very high temperature, is affected. This same solution was sorely frugality caused the «Internal combustion engines» such as missile launch to the next millennium. However, it can be said that the MYT engine will never build, but it can build a basic engine pump fun.
