Pet with advantages and price
I believe everyone has seen all kinds of packing straps or straps. I don’t know if you have found that some larger items use the same straps. In fact, they are produced by uniform specifications, specially for some items to be packed, this kind of packing belt is called pet belt. Since it is used as a special packing belt, it naturally has its own characteristics and advantages, so what is it like in the end? the following editor will give you a detailed introduction to pet packing tape, let’s have a look.
PET packing tape
PET packing belt is a kind of polyester packing belt which is extruded and stretched with PET as the main raw material. at present, it is the most popular new environmental protection packaging material instead of steel strip, steel wire and heavy PP packing belt. Since 2002, the demand for PET packing belt in China has increased at an annual rate of 500%. It has been widely used in wood, paper, iron and steel, aluminum ingots, steel pipes, profiles, glass, building materials, ceramics, electrical appliances, metal products, tobacco, chemical fiber, cotton and other industries. The appearance is transparent (opaque after adding tackifier), the surface is smooth or just has a prismatic pattern.
Pet belt advantage
1) save money 50%: through the comparative analysis of the performance of PET plastic steel belt and steel strip and practical data, we can know that the use of PET plastic steel belt can completely replace the same specification of steel strip or the same tension strength steel wire packaging goods. According to the calculation, under the same specification and equal length, the weight of the plastic steel strip is only 1 / 6 of that of the steel strip, and the packaging cost can be saved by 50% by using the plastic steel strip instead of the steel strip to pack the glass.
2) Safety: PET plastic steel belt can maintain 5% tightening force for a long time, does not return loose, and has 5% cushioning elongation when it is hit by a strong external force to ensure the safety of the packaging. The PET plastic steel belt does not have the sharp edge of the steel belt and will not cause damage to the packaged object, nor will it cause any harm to the operator in the process of packing and unpacking.
3) Environmental protection: PET plastic steel belt is made of food-grade packaging materials, with moisture-proof, anti-rust, waterproof, anti-corrosion characteristics, will not cause pollution to the packaging, meet the requirements of environmental protection, and there is no restriction on export after packaging. The used PET plastic steel strip can be recycled and there is no pollution in the recovery process.

The pet belt introduced in this paper is an environmentally friendly product, durable and wear-resistant, easy to use, small in quality, and will not increase the weight of the goods, which is the reason why it is widely used.
When wire rope is used as mobile lifting equipment, how much is the safety factor when strapping the sling?
Generally speaking, the safety factor of cargo lifting is 6 and that of carrying persons is 12. The breaking force of the sling is generally 75% of the minimum breaking force of the wire rope, which is for reference only.
The types of wire ropes commonly used in equipment are as follows:
1. Phosphating coated steel wire rope (Chinese patent), after manganese or zinc-manganese phosphating treatment, the surface wear resistance and corrosion resistance of steel wire jump in an all-round way, and the compound effect of phosphating film and grease can effectively restrain the occurrence of fretting wear. the wear problem of steel wire rope is solved completely, and the fatigue life is 3 times that of smooth steel wire rope with the same structure. Fatigue life can be verified by fatigue test (fatigue test is the most reliable) It is an upgraded product of smooth steel wire rope, and it can also be used instead of galvanized wire rope with thin galvanized layer after plating (can be tested by salt spray test or compared with corrosion resistance). It has the advantages of long service life, lower unit cost and better stability.
two。 Galvanized steel wire rope, including hot-dip galvanizing and electrogalvanizing. Generally speaking, hot-dip galvanized layer is thick and electrogalvanized layer is thin.
3. Stainless steel wire rope, mainly 304 or 316 stainless steel, excellent anti-corrosion effect but expensive
4. Plastic coated steel wire rope, carbon steel wire rope, coated with polyethylene, polypropylene or nylon
5. Smooth steel wire rope, with short service life and sharp decrease in market demand, will be completely eliminated by phosphating coated wire rope.
6. Steel wire ropes for mooring in marine engineering
7. Cable wire rope
For lifting appliances used in atmospheric environment, manganese phosphating coated wire rope is preferred, hot-dip galvanized-phosphating double-coated wire rope is preferred in heavy corrosion environment, and marine steel wire rope is preferred in sea water. When purchasing, please note that the name of the wire rope must be indicated in the purchase invoice, such as phosphating coated wire rope or 316 stainless steel wire rope, in order to protect its legitimate rights and interests. in addition, patented products are generally sprayed with patent number on the outer packaging of steel wire rope. the warranty shall have main technical indicators, such as the type and weight of phosphating film, for reference only.
What’s the name of a machine that can bind people?
Bundling machine refers to the machine used to bind grass. It has the following characteristics:
First, a wide range of applications, can be used for rice straw, wheat straw, cotton stalk, corn stalk, rape stalk, peanut vine. Bean stalks and other straws and forages are picked up and bundled
Second, there are many supporting functions, you can pick up bundles directly, you can also pick up bundles after cutting, and you can crush bundles before bundling.
Third, high work efficiency, 120 million mu of bales can be picked up every day, with an output of 20 million 50 tons.

Divided into hydraulic baler and tractor towed baler, from the original point of view is divided into corn straw baler, wheat straw baler, rice straw baler and so on.
Develop
In the 18th century, the transportation and agricultural production of many countries were driven by horses, so a lot of hay was needed to raise horses in the vast urban and rural areas, and the hay should be pressed and bundled when transporting it. In 1853, Emory of the United States invented the straw baler, which made the bales strong and convenient for transportation. This kind of bundling machine is a horizontal press, which is equipped with a function such as a piston baffle at each end of the bundling. when the grass is put in the box, Malaysia pulls a set of chain and pulley mechanism. in this way, the baffles at both ends of the bundling box move opposite to each other, thus pressing the straw. This baling machine can pack 5 bundles of straw per hour, each weighing 125 kilograms, and its disadvantage is that when the machine is running. Workers are still needed for auxiliary work [2].
In 1872, American Dedrick developed a continuous production baler on the basis of Emory, which achieved great success in the United States and Britain, thus speeding up the pace of production.
Due to the need to continuously improve the production capacity, a steam pressure baler was developed in 1884. After this kind of baler presses the grass into bundles, the person bundles the hay, and then automatically pops up the bales.
In 1871, the American Walter Wood obtained the patent for the steel wire baler, which was excellent at that time and was exhibited in Britain.
In 1858, John Fay Appleby invented the rope baler, but because the rope was expensive, the technology was not developed until 20 years later. It was easy to use and smart. In 1878, the bundling machine produced by manufacturer Dilling adopted Appleby’s bundling method.
Before 1958, the bundling machine could only beat the wheat bundles into rectangles. In 1958, the Ellis Chalmers Company of the United States put the cylinder baler developed by Roto-Baller into commercial production, which could bind the wheat straw into cylinders with a diameter of 36-56 centimeters and a length of 0.91 meters. Each bundle of 18mura 45 kilograms is still in use in some places.
Control and maintenance
1. Choose according to two kinds of pick-up width, adapt to different pick-up width operation, the strength is super.
2. The compression mechanism assembly is located at the upper part of the pickup mechanism assembly, with the same pick-up frame.
What is the general way of flattening steel wire flattening machine?
Steel wire flattening generally uses rolls, which can be installed on the wire drawing machine.
Steel wire has a wide range of uses, low-carbon iron wire can be used to bind items, and high-carbon steel wire can be used to make steel strands and manganese phosphating coated wire ropes.
