Thermosensitive material is a kind of material with poor thermal stability. It is sensitive to temperature and easy to decompose, degrade and discolor at high temperature. When decomposed, it releases corrosive or toxic gases. It is necessary to strictly control the processing temperature (e.g. polyvinyl chloride, polyformaldehyde, EVA and copolymer of vinyl chloride, etc.).
Because of its good insulation and stable chemical properties, this kind of material is widely used in the fields of electronics, electrical appliances, automobiles, transportation, aerospace manufacturing, national defense and military industry. In the production process of twin screw, high speed shear and high pressure will lead to the increase of local temperature of materials, which directly affects the processing of heat sensitive materials.

Before performing the anastomosis, the ends should be aligned to prevent one or both sides from twisting; release the sides while ensuring good blood supply to the anastomosis and ensuring that the anastomosis is tension-free.
Place your left hand around the anastomosis to protect it from foreign body entrapment. It is important not to be too loose, nor too tight. As too loose can prevent the two walls from fitting closely, which may result in the poor anastomosis, postoperative bleeding, and anastomotic fistula; too tight may result in extrusion injury to the gastrointestinal tract, causing postoperative scarring, resulting in narrowing of the anastomosis or difficulty in withdrawing the anastomosis, and in severe cases may result in tearing of the anastomosis.
The anastomosis should be performed quickly and accurately, in one single movement, to ensure that the surgical stapler does not swing left, right, up and down, so as not to aggravate the tissue damage around the anastomosis or increase the possibility of anastomotic fistula or stenosis.
The cause of the unsuccessful anastomosis should be identified immediately and an instrumental or manual anastomosis should be performed again.

We sometimes stack accessories in order to show fashion, this method is only suitable for similar accessories, if too many non-similar accessories are piled up, it will also seem to have no focus.
Do we usually wear earrings to see whether they look good or not, and ignore the important role of earrings? That's the function of earrings to modify the face shape. Different face shapes with corresponding style earrings will make you look more beautiful.
The decorative effect of the large earrings is obvious. Through the transfer of the visual center, the effect of modifying the face shape is achieved. But also note that if the earring style you choose does not match your face, it will be counterproductive.
Long earrings are very dangling, which are more suitable for girls with square faces and round faces. The button earrings have a more harmonizing effect for the girls with a long face.
If it is a standard goose egg face, then you can wear various styles of earrings.

The basic working principle of eddy current testing instrument is as follows:
When the test coil with alternating current is close to the conductor workpiece, the alternating magnetic field generated by the coil will cause the conductor to generate current (eddy current). The size, phase and flow pattern of eddy current are affected by workpiece properties (conductivity, permeability, shape, size) and defects. The voltage and impedance of coil are changed by the reaction of magnetic field.
Therefore, the change of voltage or impedance of the test coil can be measured by the instrument, and the nature, state and defect of the workpiece can be judged.
Characteristics of Eddy Current Testing Instrument
(a) Process inspection and final product inspection: quality control during manufacturing process or rejection of non-conforming products in finished products.
(a) No contact with the workpiece and no coupling agent are needed in the detection, which can be carried out at high temperature. At the same time, the probe can be extended to remote detection, which can effectively detect the narrow area and deep hole wall of the workpiece.
BKN is one of the professional ndt equipment manufacturers,we master the eddy current testing principle,we also produce ndt testing machine,we will be your best partner.

Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors), or synchronous DC motors, are sensored brushless motor powered by DC electricity via an inverter or switching power supply which produces an AC electric current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor.
Powerful brushless motor exhibit reduced energy use, long life, low noise, compact size and light weight characteristics.
Choosing a good high power brushless motor can be easy and difficult at the same time. There's a few things to take in consideration when choosing one high speed brushless motor for your plane:
1- Prop size; Do you want the plane to be fast or slow? How much clearance do you have?
2- Amps; How many amps does the motor pull? More means more power
3- Voltage; 2s or 3s lipo? 2s would be better for smaller, lightweight planes.
4- kv; kv determines how fast the motor spins. Generally the higher the kv, the smaller the prop
Keep all of those in mind and you will be able to find the PERFECT motor for your plane.
5- Thrust; How heavy will the plane be? Heavier = need for more thrust to stay airborne
Your entire plane is built around your powerful rc motor and this is what you must choose first. When considering RC brushless motors there are several pieces of information you must take into account. The first is your drone parts motor KV. The KV of your motor is the number of revolutions per minute it will spin per volt. The lower the KV, the stronger the motor and as a result, you will want a larger propeller for maximum thrust. Often slower motors will also result in slower flying planes, a big plus for your first hobby grade RC drone. If you select a rc drone motor with a higher KV and a smaller propeller the speed of the thrust will be higher, and as a result your drone will fly faster.
Shenzhen TitanFlying Technology Co., Ltd is one of the best drone motor manufacturers,we produce high speed motor for drone,welcome to order.

The neck-to-shoulder line is one of the most charming parts of a woman. The addition of a necklace is undoubtedly the icing effect on the "neck", embellishing the slender neck of the woman.
There are two statements about the origin of the necklace. One is the custom of "robbery of marriage" originating in the primitive society. During the patriarchal clan period, the status of men was much higher than that of women. They often snatched women from other tribes as their wives. To avoid their escaping, the winners used metal wires or ropes to wrap the women's necks. Later, due to social and cultural changes, a marriage token was formed.
There is also a saying from some "totem nations", who think that the neck is closely related to life, so they will choose the totem of faith to hang on their chests, and pray for the "magic" of the totem to protect their lives, and at the same time, the royal nobles also use it to show their identity and status. And if you want to buy them, for cheap, you can buy from china taobao agent.
Neckline determines the necklace length
People with long necks and strong lines often give people an elegant and distinctive feeling. They can visually elongate their height and make them stand out from the crowd. But this inherent advantage is not available to every girl. In this case, we can make up for the shortfall with necklaces.
Girls with short necks tend to give people a feeling of not being slender enough, and they may even look a little strong. Such a neck is best to avoid necklaces that are too small, such as the collar that is popular nowadays. This kind of collar will show the neckline is thick and short, and it will appear abrupt itself. Wearing a necklace with a sense of line, depending on the V-shape formed by the pendant of the necklace, has the effect of lengthening the neckline.
A slender neck will be a good match for necklaces but avoid necklaces that are too long, otherwise, the neck will look too long and cause inconsistent body proportions.
A little secret in the necklace
Do you know? The length of the necklace is not arbitrary, but it has a standard length and name.
The necklace that is usually worn every day is about 40 cm and does not require specific clothes and styles to match. 36 cm and below are collectively referred to as short necklaces; 40 cm are graduation necklaces; 42 cm is princess necklaces; 54 cm is morning necklaces; 71 cm are dress necklaces; 107 and 142 cm necklaces are called long necklaces and extra-long necklace.
In addition, the buttons of the necklace are also divided into several types, the most common buttons are the lobster button and the organ button. It is most commonly seen on the clavicle chains and relatively small and thin necklaces in summer. The lobster clasp is named because it looks very similar to the lobster. Compared with the thin and light organ clasp, the lobster clasp is thicker and heavier. The pearl buckle necklace has a stronger three-dimensional sense, and the use of pearl-like ball buckles is more integrated with the necklace. Most of the M buckles are used on gold necklaces, which are connected by hand breaks. This kind of buckle is not prone to instability and breakage at the interface.
As the china agent for taobao, we are the cheap taobao shops. Welcome to consult. In fact, no matter what kind of material or style, it will not affect the beauty that the necklace gives you. It allows you to have a super-slender neck, which makes people have to love.
At present, pvc membrane welding machine has been widely promoted in a number of plastic welding industry. Various welding defects are inevitable in the process of use. In this article, it mainly analyzes how to solve the problems in debugging or welding.
1.Crush and bruise
Pressing injury and abrasion are common problems in the process of pvc membrane welding machine. Sometimes it's not so serious, and it just gets white or marks. When you encounter such problems, the first thing to do is to ensure that the location of the tooling is not out of alignment. First let off the air of the cylinder, press down the welding head, and carefully observe whether the welding head position of the scratch is correct. If the welding head is in the correct position, or if the abrasion or compression occurs on the support (or lower cover), then it is necessary to observe whether there is any interference between the tooling and the product. If it is old tooling, it is suggested to clean the tooling with alcohol at this time. If it is a new fixture, lightly rub the scratch (especially at the bottom of the step) with sandpaper to prevent burrs. In addition, observe whether the air pressure of the cylinder is too large during welding, whether the film of the pad has not been changed for a long time during welding, or whether there are foreign bodies stuck on the film.
If the above work is done, the pressing injury still exists, it can be basically judged as the interference of tooling. At this time, the mold shall be modified according to the size and location of the pressing injury:
(1)slight pressing injury. File the sharp Angle of the tool at the corresponding place of the tool, blunt the sharp Angle of the tool, and then use sandpaper polishing;
(2)the pressing injury is serious, but there is no welding rib at the corresponding place. Rub off the interference part of the fixture with an air abrasive rod (be careful not to touch other parts, especially the root part of the air abrasive rod, which may be rubbed off other places without being noticed). After grinding, make it smooth with whetstone and buff with sandpaper;
(3)severe crush injury. If there is welding rib in the corresponding place, or if there is serious pressing injury and the interference part is very large, please consult with the designer. Have the processing center dealing with the modified drawing and contact the relevant personnel to confirm whether there is a problem with the injection molding, or whether to improve the product structure.
2.Material overflow
If there is any overflow in the welding process of pvc membrane welding machine, do not debug or modify the welding parameters right away. First measure the size after welding, and compare it with the normal value. Adjust according to the difference.
3.Insufficient welding strength
If it is old tooling, first stick the product on the welding head, observe whether the gap between the product and the welding head is too large in the weak welding place, to determine whether the welding head is worn; if it is a new tool, please scan it with the welding head, observe its frequency, power and curve, and make sure there is no problem with the welding head.
We are one of the professional rf welding supplies, we produce pvc membrane machine, warmly waiting for your order!

Pulsed eddy current inspection technology is a new non-destructive testing technology for subsurface defect detection. It is a new application field of eddy current testing. It determines the location of defect by the time when the maximum magnetic field appears, so as to realize non-destructive detection and quantitative description of defect.
As early as the 1970s, Libby of the United States put forward the theory and application of pulsed eddy current inspection technology. However, in recent years, this technology has made some substantial progress and success in the University of Iowa in the United States, DERA in the United Kingdom and Cegely Laboratory in France, and has attracted much attention in the research and development of modern non-destructive testing technology. Compared with the traditional single-frequency sinusoidal eddy current, the pulsed eddy current has many advantages.
Traditional eddy current uses sinusoidal current of a single frequency as excitation, while square wave with a certain duty cycle is used as excitation in pulsed eddy current inspection. The traditional pulsed eddy current inspection is used to analyze the steady state of the induced magnetic field, that is, to determine the position of the defect by measuring the amplitude and phase angle of the induced voltage, while the pulse eddy current is used to analyze the transient state of the induced magnetic field in time domain to detect the defect by the time when the maximum value of the induced magnetic field appears directly. In theory, pulsed eddy current can provide more information than single-frequency sinusoidal eddy current, because pulsed eddy current can provide a range of continuous multi-frequency excitation.
In addition, the pulsed eddy current inspection signal responds faster than the multi-frequency eddy current signal because it runs a different current frequency at the same time.
Nanjing BKN Automation System Co., Ltd. is one of the perfect mfl suppliers,we provide ndt testing,pulsed eddy current equipment and pulsed eddy current testing equipment,RFQ today!
