sealed round pail has a strong application, widely used in daily necessities, daily chemical packaging and other fields. From mold processing to machinery and equipment are extremely picky, easy to get started, difficult to do fine. Due to its light weight, good preservation, emphasis on heat, pressure and other technical trends, sealed round pail has become the mainstream of drinking packaging today. From the perspective of recycling, how to choose the label material of sealed round pail?
In the sealed round pail recovery process, the label separation goes through several steps:
1. Peel the label off the bottle with the de-labeling machine, and separate the bottle from the label with the wind;
2. Using the method of water separation, the label with a lighter weight than the bottle is separated from the bottle under the buoyancy of water;
3. After the bottle is cleaned and dehydrated, the lighter label is sucked out again by suction.
At present, the domestic sealed round pail label is mainly PVC, due to the close density of PVC and PET, there is a certain difficulty in sorting, but the mixture of PVC seriously affects the quality of the bottle. Therefore, sealed round pail's recycling process is targeted to remove PVC, and even uses professional bottle separator needles to reduce the PVC in the bottle sheet to a certain level, but it is expensive.
PET labels in foreign countries mostly use PET and OPS, and Coca-Cola, PepsiCo, Procter & Gamble, Unilever and other companies have begun to use PET labels since 2010. In Japan, consumers need to peel off the label from the bottle and classify it for recycling, which has very high requirements for the label, and the tear strength of OPS is small, which is more suitable.
Domestic garbage classification work is still in the development stage, there are no mandatory laws and regulations requiring sealed round pail and label classification recycling, but whether the label is easy to tear will greatly affect the level of domestic bottle grade PET recycling slices, with the increasing concept of environmental protection, the label is easy to tear, stripping requirements, Will be a great challenge for PET.
Domestic enterprises that have been engaged in sealed round pail recycling for many years suggest that PVC labels have always been the stubborn disease of sealed round pail recycling, and if the labels are selected with PE, PS and other materials with different PET densities, they will be easier to separate.

It was sultry, torrential rain, lightning and thunder. In such an environment, how to better maintain automatic transfer machine?
The Yangtze River is vast, with thousands of embankments. In summer, the weather gets hotter and hotter and there are more and more thunderstorms. Many parts of southern China have seen heavy rains and even floods in some areas. However, many CNC machine tools, including automatic transfer machines, tend to ignore the maintenance of equipment because the production workshop is small and stuffy, and in this weather, the equipment is more prone to failure.
In order to give full play to the performance of automatic transfer machine and extend the service life of machine tool, the following points should be paid attention to:
1. No one is strictly prohibited, no matter how good the CNC machine tools need the care of the operator, although the automatic machinery should always pay attention to the abnormal automatic transfer machine and timely processing, do not be careless.
2. Create a good environment for use
For the user, it's mostly the details. Maintain good air circulation and ventilation. Pay attention to the humidity and humidity of the air. The relative humidity should be between 40%-60%, and the indoor temperature should not be higher than 35. Although the machine is made of steel structure and cast iron, the circuit boards, circuits and electronic components of the control system are prone to damage due to humid air. And pay attention to the details of the work, such as the rainy season, pay attention not to bring an umbrella to the production site, do not change wet shoes at the processing site.
3. Strive to improve the utilization rate of machine tools
After the purchase of CNC machine tools, if its opening probability is not high, it will not only let the user invest in the role of reproduction, but also let the warranty period worry, because no matter what equipment, it has a warranty period, users must make full use of the machine tool during this period, so that the thin part is exposed as soon as possible, in order to deal with the warranty period. Usually lack of production tasks, and can not be idle. It's not a love kit. On the contrary, due to long-term non-use, deterioration or damage to electronic components may be accelerated due to moisture and other reasons. The operator of the CNC machine tool should be powered on regularly, idling for about 1 hour each time, and use the heat generated during the operation of the machine tool to reduce the humidity in the machine tool.
4. Fire extinguishers should be equipped next to the machine tool
Check the timeliness of the fire extinguisher at least once a day to ensure that the fire extinguisher pointer is in the green effective range. In this wet weather, it is difficult to ensure that the fire extinguisher has been used normally, and the wet environment may damage the function of the fire extinguisher and find that it cannot be used when it is needed.
5. Precautions for spark fluid in machine tool processing
In the machine tool processing, the temperature of the EDM fluid should not be higher than 50, and the temperature is too high, the processing should be stopped. At the same time, pay attention to the level of EDM liquid in the tank, and make up for any shortage in time. In addition, pay attention to the cleanliness of the EDM solution. If the oil is found to be black, the filter element should be replaced in time.
6. Strictly abide by safety rules
CNC machine tools must be strictly grounded, the use of three-core power plug, reduce static interference, improve machine stability, protect the operator.
And because of the excessive power consumption in summer and thunderstorm season, the voltage of the power supply line is often unstable, leading to failure and even burning parts such as drivers. If possible, stop the equipment to prevent lightning. Or buy the right type of regulator. 7. At the same time, strictly implement other maintenance items specified in the manual.

Lawn and vegetation may have different Angle trimming requirements when pruning, such as horizontal pruning, diagonal pruning or vertical trimming, which requires the use of arc blade hedge trimmer, and blade is an indispensable part of arc blade hedge trimmer. Choosing the right arc blade hedge trimmer can greatly improve the efficiency of lawn and paper cup trimming. What parameters should be paid attention to when purchasing blades?
1, consider the material. The quality of the blade depends on the choice of material. According to the different blade material, its service life, processing efficiency, surface quality and other aspects also have significant differences. Commonly used blade materials are high-speed steel, carbide, ceramic cutting tools, etc.
Among them, the high-speed steel blade is a commonly used economic blade, which is suitable for the processing of general steel, but the processing effect of wear-resistant materials is poor. Carbide blades are the choice of high strength and high hardness, widely used in the processing of steel and cast iron, but the cost is relatively high. Ceramic tool is a new material, strength and hardness are relatively high, can cope with high hardness processing.
2, consider the processing material. Different processing materials have different requirements for arc blade hedge trimmer blades. Generally speaking, steel processing requires large cutting force, but the wear is slow, and the cutting speed is relatively fast; For the processing of wear-resistant materials, the cutting force is required to be small, but the wear resistance needs to be improved to prevent the blade from wearing too quickly, resulting in reduced processing efficiency.
3. Consider the geometry of the blade. The geometrical shape of the blade has a significant effect on its machining effect. Generally speaking, the tool milling diameter is larger, the processing surface is rough, and the tool milling diameter is smaller, the processing surface is more smooth and flat.
When selecting the blade geometry, it is necessary to take into account the shape, material height, structure and other characteristics of the material to be processed in order to achieve high efficiency, low abrasion resistance and good cutting quality.
4. Note the tool geometry parameters of the arc blade hedge trimmer blade. The geometric parameters of the tool include the edge Angle, the edge Angle and the edge intersection Angle. The tool edge Angle depends on the material to be processed, the general edge Angle to make the tool in cutting to maintain a greater strength, and the edge cutting is required to have a better feed effect, remove the film of the cutting part and wet grind a layer of basically flat surface.
The Angle of the edge intersection Angle is usually between 10° and 20°, and the small edge intersection Angle can reduce the cutting force, reduce the heat and film thickness; The large edge intersection Angle can improve the hardness of the tool, so that its life is long and the machining result is better. The choice of edge Angle should be based on the material of the object to be processed, but also consider the cutting force and thermal resistance.
Choosing the right arc blade hedge trimmer takes into account a number of factors, such as material, machining material, geometry and tool geometry parameters. Sometimes, the conventional size specifications of the blade on the market may not meet the actual use needs, which requires customization to the blade manufacturer.

White Bubble Sleeve Tops are favored by many people, because white Bubble Sleeve Tops are the best match, but white Bubble Sleeve Tops are also the hardest to wash. The collar and sleeves of Bubble Sleeve Tops are the most difficult part of Bubble Sleeve Tops to clean, and tend to turn black and dirty. In fact, as for the washing of Bubble Sleeve Tops, the custom personnel of Chengdu Bubble Sleeve Tops believe that the many collar cleaning, bow tie cleaning, spraying, wiping, brushing and coating on the market all make Bubble Sleeve Tops easy to wash. It should be noted that, Bubble Sleeve Tops must not be worn until it is seen by others as dirty before washing. One is to affect the image, and the other is difficult to wash back to the primary color. The collar lining materials of Bubble Sleeve Tops are mostly linen or resin linen. In order to keep it flat and straight without deformation, it is not appropriate to twist and kneel with force.
When washing the collar and Sleeve, spray the inner ring (the part in contact with the skin) with a good quality detergent first, lay the Bubble Sleeve Tops flat for 5-10 minutes, then immerse the collar and sleeve tops in water dissolved with detergent powder, turn them up, fold them in half toward the collar and sleeve sockets, and rub them flat back and forth with one hand on top and one hand on bottom to make the collar and sleeve self-friction. Instead of using the traditional irregular scrubbing, so that the collar and sleeve after washing do not wrinkle, do not blister, 100 wash often new.
If you have a steam iron at home, you can iron your own Bubble Sleeve Tops, don't worry. Of course, when ironing the collar and sleeve, the inner ring should be sprayed with a little water, and then ironed with steam, the effect will be better.

There are various types of chains, including the straight side plate roller chain and the double speed chain. What we need to understand about the straight side plate roller chain is its fatigue failure, and for the double speed chain, What is more important is its proper use. The mastery of these knowledge is good for extending the service life of the chain.
Because the mechanical equipment often needs 24 hours not to stop running, so as an important part of the straight side plate roller chain will need to have high requirements, because if a certain fatigue value is reached, the chain will soon fail.
If the straight side plate roller chain bears excessive load during operation, resulting in uneven force, it is easy to break or be squeezed. Because the tension of the chain on the loose side and the tight side is different, the chain works in the alternating tension stress state, and after a certain number of stress cycles, the chain will be damaged due to insufficient fatigue strength.
In the face of the failure of the straight side plate roller chain, it is usually only solved by strengthening the parts, such as carburizing the surface of the parts to resist stress concentration; Widen the waist width of the chain plate to ease the stress concentration of the hole; The parts are shot peening treatment.
The double speed chain is usually only used in the double speed chain conveyor, and through its growth function, the tooling plate that supports the goods on it runs quickly and reaches the specified position. In the normal use of the equipment, due to normal or accidental wear of the speed chain may appear a variety of abnormal phenomena, at this time must immediately stop the use, timely repair, in order to avoid major accidents.
However, if non-professional maintenance personnel or without the permission of professional maintenance personnel, it is not possible to repair the double speed chain by itself; At the same time, the power supply must be turned off for maintenance, and live operation is not allowed.

Under the condition of the same paper and ink, due to the problems in the operation process, the finished luster of the album is often different after printing. Without considering the gloss treatment after printing, what are the ways to improve the gloss of custom Spiral YO book printing? Let's take a look!
1, improve the acid wetting fluid
The acidic wetting liquid used in China for decades is mainly chromic acid and phosphoric acid, although diluted, the PH value is still between 3.5 and 5.6. The stronger the acidity is, the greater the resolving power and corrosive power of ink binder and pigment, resulting in rough surface of imprinted film and reduced gloss.
2, reduce ink emulsification
The excessive emulsification of ink in offset printing is mostly caused by large amounts of water and ink in the operation, and the ink layer looks very thick, but the ink molecules have become a state of oil in water, and the luster is very poor after drying, and a series of other failures will occur. Large ink is a very taboo in offset printing, to change this situation, in addition to the quality of operation and technical improvement, it is recommended to use wetting powder, because it has better performance, even if the layout moisture is smaller, it is not easy to dirty. It is easy to operate and makes the finished product shiny.
3, the correct use of dry oil
For advanced bright fast drying ink, under the condition of normal temperature and humidity, it has enough drying capacity. In case of the following situations should be added drying oil: first, in the winter temperature, humidity is low; The second is that the ink should be added in the case of anti-stick agent, removal agent, thin ink oil, etc., should be added to the drying oil. In the process operation, the correct use of dry oil is very beneficial to the formation of gloss in the finished product. This is because the paper takes a certain amount of time to absorb the binder, and in this process, the binder condenses as soon as possible until the conjunctiva is dry, which is the key to the finished product's good luster.
4. Add the diluent
When some ink color is too deep to meet the requirements of spot color printing, it needs to be lightened, which can not only make the ink lighter, but also improve the gloss of the printing product.
5. Add glossy paste
The gloss paste is processed from raw materials with high gloss, which can increase the gloss of the ink, but the amount should not be too large, otherwise it will reduce the drying speed of the ink, and the phenomenon of sticky and dirty and drawing will affect the gloss.
6. Adjust the machine correctly
Whether the thickness of the imprinted ink layer meets the standard also has an impact on the gloss. For example, the pressure regulation is poor, the dot expansion rate is high, the ink layer thickness is not up to standard, and the finished product luster is slightly poor. Therefore, the pressure should be adjusted well, so that the expansion rate of the dot is controlled at about 15%, the ink layer of the printed product is thick, the layer is pulled open, and the luster is also there.
