Why should we buy lift rather than rent it?

 For working machinery, safety is the user's highest priority for aerial working equipment. The usual working height is 10 to 20 meters. This height is a certain risk for the operators, so the safety of the equipment and the standardization of operation its the most important thing, and talking about the equipment itself, a brand-new lift you buy is safer and can guarantee the safety of workers and construction efficiency, while the leased lift usually has a higher number of used hours and years of equipment. There is a great potential safety hazard, which cannot be ignored, and untimely service will also seriously affect the workload of the project, resulting in a decrease in construction efficiency and a disguised increase in rental costs.

 

Many lessors cant treat customers honestly. They usually replace some of the original logos of lift with famous brands, so that the same lift can make the rent higher. At the same time, there are also changes to the lift model. The original basic information of some equipment, such as production date, origin, etc., reduces the working hours of the product, so that you feel that the use value is higher and that it is worth the money.  But if you choose to buy, then all the risks can be avoided. After all, after the machine is produced and debugged, you get a completely new machine. You have absolute power over the equipment and there is no situation of being fooled, you know best of all the situations.

 

The greater risk of leasing is that some leasing companies will perform simple repairs, repainting, and refurbishment of the lift that is accidentally or the lift that should be scrapped, replacing the old with the shoddy. There is a great safety risk!

 

Sometimes, when your leased lift fails, some leasers will deliberately exaggerate the fault, allowing you to bear greater repair costs or parts replacement costs.  After you purchase, you can directly contact our manufacturer if you have any situation, our engineers will understand the situation in time, and give you the rightmost solution, and strive to solve the mechanical failure you encounter in time with the simplest and effective method.

 

In addition, as far as leasing is concerned, no matter what your current financial situation is, whether you have sufficient funds or a temporary shortage of cash, you must pay the rent on time, or you will bear the risk of default and compensation. And when buying a brand new product, there is no worries about the future progress of the project, or the increase in rent caused by the increase in the lease time due to various reasons.

 

After we purchase lift, you can process our lift at any time according to your needs, whether it is used for mortgage or leased when it is idle, you can fully own all the value of lift. Usually the engineering work cycle is long and the lift is used frequently, so we can use it easily after purchase and we need to use it at any time.  Avoid the trouble of various leasing procedures.

 

And if you rent, you only have the right to use lift, but no ownership, so you can't modify lift according to the working environment during the operation, which has great limitations. One of the biggest advantages of buying a new lift is that you can tell us your requirements and we can customize it, including color, power, and platform size. Jinan Tuhe Heavy Industry Machinery Co., Ltd. is a company dedicated to the development and production of hydraulic lifts. We can provide you with various types of scissor lift, boom lift, mast lift, and etc. Whether it is wheeled traction or crawler self-propelled, we can provide you with it. The color can also be based on your personal preference. Including some detailed requirements for lift, we can also customize it for you. In addition, there are many times to work in different operating environments, and there are different situations in the choice of power. And our advantage is that we can customize it for you. Provide a variety of power, whether it is AC or DC, or petrol or diesel. According to your requirements, we can provide a single power source. If necessary, we can also provide you with dual power or multiple power to make your lift. The maximum degree is not affected by the operating environment to achieve the operation. scissor lift manufacturers

 

And after big data and many results show that, usually the total rental cost of a lift is often higher than the purchase cost of a lift.  Moreover, there will be a lot of troublesome troubles in the leasing process, which is difficult to solve in time, which will have a great impact on both of us and the progress of the entire project.

 

What are the raw materials of the wig?

 The raw materials of wigs can basically be divided into two categories: man-made fibers and human hair. The wigs on the market are basically processed from these two kinds of raw materials.

 

1. Man-made chemical fiber

Artificial chemical fibers are collectively referred to as chemical filaments in the wig industry. They refer to chemical fiber materials synthesized through chemical "spinning" or "blowing" processes. They are similar to human hair wigs and are a supplement to human hair raw materials. The more famous ones are Japanese kanekalon and toyokalon. In the early days, the most expensive one was PP material (also called P material, namely polypropylene chemical fiber).

 

The synthetic chemical fiber silk mainly includes: normal temperature silk, high temperature silk, protein silk and other common products; according to its origin, it can be subdivided into domestic silk, Japanese silk, Korean silk, etc.; according to its reflectivity, it can also be divided into domestic silk, Japanese silk, Korean silk, etc. It is ordinary silk and matte silk.

Normal temperature silk: Normal temperature silk is generally used as a filling material in human hair products, which can effectively reduce the cost of human hair products. But the shortcomings are also obvious: easy to deform, difficult to manage, not resistant to high temperatures, and are flammable items. However, there are also wig products made of pure room temperature silk on the market. Because of their low price, they were also popular in the early days. However, the shortcomings of products made with room temperature silk are also obvious: the degree of realism is poor and it is not conducive to maintenance; They are basically disposable products, so they have been gradually eliminated in recent years.

 

High temperature wire: Compared with normal temperature wire, high temperature wire has a great improvement in high temperature resistance. Theoretically, it does not exceed 160 and will not deform the high temperature wire. (In actual applications, according to the different production process of high temperature wire, The temperature ranges from 100°C to 160°C). Under the condition of controlling the temperature, it can be hot, easy to take care of and save, and its fidelity is also greatly improved compared with that of room temperature silk. Therefore, in recent years, many wig products on the market are made of high-temperature silk raw materials (materials), of course, the price is more expensive than normal temperature silk.

 

Protein silk: With the development of the wig industry, customers have higher and higher requirements for products, and low-end products can no longer meet the needs of customers, so there is a higher-quality raw material such as protein silk. Compared with normal temperature silk and high temperature silk, protein silk has achieved a further level of fidelity. So far, it is a kind of raw material that has the closest feel and fidelity to human hair. It is often used in making high-end wigs. So the price will be more expensive compared to the first two.

 

In the course of continuous development of synthetic chemical fiber, an upgraded product that is different from ordinary silk has been derived: flame-retardant silk. The difference between flame-retardant silk and ordinary chemical fiber is that ordinary chemical fiber is easy to burn and becomes lumpy after being ignited. , And flame-retardant silk is not easy to burn. After being ignited, it is the same as human hair and becomes a powder, which reduces the risk of use. However, because of its high cost, it has not been widely used.

 

2. Human hair

 

According to different regions, human hair can be divided into: China hair, India hair, Brazil hair, Myanmar hair, Vietnam hair, Mongolia hair and so on. Because of its material, it can be ironed and dyed, and is easy to store. However, the output of human hair is limited, and the price of human hair products is slightly more expensive.

 

The main difference between human hair in different regions lies in the hair quality and curvature. Chinese hair, Mongolian hair, Burmese hair, and Vietnamese hair are all Asian hair, and the hair quality is relatively straight. Among them, Chinese hair is the best, and Chinese hair feels smooth. Slippery, the most expensive. Brazilian hair and Indian hair are softer in hair quality and have a slightly larger curvature. They are suitable for European and American hairstyles and are mostly used for hair extensions. Among them, Brazilian hair is the best.

 

I believe that through this article, everyone has a general understanding of the raw materials of wigs; if you have other questions about wig products, you can contact us (DOLLZ HAIR) at any time, and we will answer every readers question. And we will regularly release articles related to wig products for everyone. hand tied weft vendors

The difference between fluorescent brightener OB 184 and OB-1 393 Pakistan

 The difference between fluorescent brightener OB 1,flouwhite OB and OB-1,Optical brightener OB & OB-1,Pakistand Brightener OB & OB-1

 

Although they are two different chemical substances, from the naming, it can be guessed that there are many similarities between the two. For example, the fluorescent brighteners OB and OB-1 have a wide range of applications. Most of the plastics OB and OB-1 can be used universally, and the whitening and brightening effect is obvious.

 

The difference between Fluorescent brighteners OB  and OB-1

Fluorescent brighteners OB and OB-1, these two products look the same as brothers, thought they are products of the same series, in fact, they are two completely different substances.

 

The differences of the physical parameters of the Fluorescent brighteners OB and OB-1 :

Fluorescent brighteners OB physical parameters:

Chemical name: 2,5-bis(5-tert-butyl-2-benzoxazolyl)thiophene

Molecular formula: C26H26N2O2S

Fluorescent brighteners OB-1 Physical parameters:

Chemical name: 4,4-bis(2-benzoxazolyl) stilbene

Molecular formula: C28H18N2O2

Molecular weight: 414.45

Content: 99.5%

Ash content: 0.5%

Appearance: yellow or yellow-green crystalline powder

Melting point: 355360°C

Compatibility: soluble in organic solvents

 

The difference of molecular formula of Fluorescent brighteners OB &OB-1

The molecular formula of Fluorescent brighteners OB is C26H26N2O2S, and the molecular formula of OB-1 is C28H18N2O2. From the above picture, we can clearly see that the two are completely different chemical substances.

The difference between the uses of Fluorescent brighteners OB and OB-1.

Although they are two different chemical substances, from the naming, it can be guessed that there are many similarities between the two. For example, the fluorescent brighteners  OB and OB-1 have a wide range of applications. Most of the plastics OB and OB-1 can be used universally, and the whitening and brightening effect is obvious. So, where is the difference?

 

1. The difference in melting point: OB-1>OB

 

Because the melting point of the optical brightener ob is 200 degrees, and the melting point of ob-1 is as high as 360 degrees, this determines that the optical brightener ob cannot be used for high-temperature plastic products, such as air conditioner casings and some kitchen utensils. Therefore, if your product requires high temperature processing, optical brightener ob-1 is your first choice.

 

2. The difference between dispersion and stability: OB>OB-1

 

Here, I must first explain that good dispersibility means that the product is easier to dissolve and evenly. For example, paint and ink have high requirements for the dispersibility of the fluorescent whitening agent; good stability means that the product is not easy to migrate and yellow in the later stage. For example, some inferior shoe soles were white and white when they were first bought, but they turned yellow and discolored after a short time. This shows that the stability of the fluorescent whitening agent is poor.

 

Of course, I am not saying that the dispersion and stability of the optical brightener ob-1 is not good, but it is slightly worse than ob. Because of this difference, we generally do not recommend the use of optical brightener ob-1 in ink coatings and soft plastics. Ob is relatively better in dispersibility and weather resistance, and yellowing migration is less likely to occur.

 

3. The price is the biggest difference between OB and OB-1

 

In fact, the biggest difference between the optical brightener OB and OB-1 is the price. When the fluorescent whitening agent first entered the market, their prices were similar, but due to the continuous increase in the production capacity of OB-1, the price also slowly dropped. Therefore, customers who can use the optical brightener OB-1 should choose OB-1 as much as possible. Those who have special requirements, such as high-end ink coatings and soft plastics, are recommended to use OB.
