SOME EXPLANATIONS OF OUR COMPANY ON POWER RATIONING IN CHINA
To our dear customers:

I believe you have heard about it. Recently, a round of large-scale power cuts has spread among factories in China, but what I want to talk about may be different from what you saw in the news. Although the “stop production and curtailment” sounds a bit “sensational”, in fact, our company’s power outage only lasts for 2 days (Figure 1 and Figure 2). According to the information I have learned, the surrounding companies also only have a few days, mainly some Energy-intensive enterprises. Companies that consume more energy and use electricity for a long time have power outages. Our company is listed as a high-tech enterprise in the zone and enjoys protection. Power outages have limited impact on our company.

Based on relevant domestic and foreign media reports, the Chinese government has made adjustments to related policies and increased imports of coal and electricity to minimize the impact on production and business activities.

In summary, please rest assured that your order will be completed within the specified delivery period with quality and quantity guaranteed(Figure 3).

UNDERSTAND WHAT IS HYDROGEL IN 1 MINUTE? WHAT IS IT USED FOR?
[Science Definition]

Hydrogels are networks of hydrophilic polymer chains, called colloidal gels, in which water is the dispersion medium. Three-dimensional software is due to the hydrophilic polymer chains held together by cross-linking. Due to the cross-linking, the structural integrity of the hydrogel network will not be dissolved by high concentrations of water (doi:10.1021/acs.jchemed.6b00389). Hydrogels are also highly absorbent (they can contain more than 90% water) natural or synthetic polymer networks. The term “hydrogel” first appeared in the literature in 1894 (doi:10.1007/BF01830147). Initially, research on hydrogels focused on this relatively simple chemically cross-linked polymer network to study its basic characteristics, such as swelling/swelling kinetics and equilibrium, solute diffusion, volume phase transition and sliding friction, and Research such applications. Such as ophthalmology and drug delivery. With the continuous development of hydrogel research, its focus has shifted from simple networks to “response” networks. At this stage, various hydrogels that can respond to changes in environmental conditions such as pH, temperature, and electric and magnetic fields have been developed. A hydrogel actuator that responds to electric and magnetic fields is proposed. However, the hydrogels at that time were usually too soft or too brittle mechanically, which greatly limited their potential applications. With the advent of the new millennium, hydrogels have also entered a new era, with breakthrough improvements in their mechanical properties. This success has led to many interdisciplinary studies of hydrogels. Nowadays, a variety of chemical methods with energy-consuming structures can be used to make hydrogels that are stronger than muscle and cartilage. In addition, it also achieves other functions, such as self-healing, multiple stimulus responses, adhesion, super wettability, etc. The innovative development of strong hydrogel has greatly expanded the potential applications of this material in various fields, including soft robots, artificial organs, regenerative medicine, etc. (doi:/10.1021/acs.macromol.0c00238).

What liquid band-aids is:

Liquid band-aid is a medical dressing with tissue adhesion ability, and can also be used as a medical tissue adhesive.

Liquid band-aid is made by dissolving film-forming materials in a solvent, and tightly adhere to the wounded part of the skin by smearing or spraying, forming a translucent protective film. It has the characteristics of bacteria isolation, breathability, waterproof, easy to use, easy to observe wound conditions and promote wound recovery.

Liquid band-aids include two types

One is an over-the-counter skin protectant that can protect surface abrasions and chronic bedsores; the second is a tissue adhesive used for surgical sutures to treat severe skin tears. Liquid band-aids are derived from band-aids and belong to the category of medical devices. Because they have a hemostatic effect, they belong to class II or class III medical device products. However, liquid band-aids that contain drugs or have pharmacological effects cannot be registered and managed as medical devices. They must be handled in accordance with drugs. manage. At present, more and more attention is paid to liquid band-aids in China.

Application of of liquid band-aids:

Liquid band-aids have a wide range of clinical applications, and can be used in surgery, burns, obstetrics and gynecology, emergency departments, dermatology, clinical care (pressure sores, intravenous care, etc.), daily injuries, etc.

Problems and prospects of liquid band-aids:

At present, the main problems of liquid band-aids include the following: few types of film-forming materials; poor film-forming properties of existing film-forming materials; pungent smell and tingling sensation. The main constraint on the development of liquid band-aids is that there are fewer film-forming materials. Foreign film-forming materials are mainly explored from industrial film-forming materials and discover polymer hybrid materials that can be used to prepare liquid band-aids;

Liquid band-aids are easy to use, have a wide range of applications, and have great development value. Moreover, the liquid band-aid can be used as a coating agent after adding drugs, and can learn from each other and develop together with the coating agent. In addition, liquid band-aids can also be combined with other technical means for real-time monitoring, which has broad application prospects in the medical field.

The company's current liquid band-aids have strict quality requirements, and the quality is the same as that of 3M liquid band-aid. If necessary, you can contact for testing.

For the superficial (tumor) target area, whether it is the traditional electron beam irradiation technology or the conformal intensity-modulated X-ray irradiation technology, when the radiation passes through the superficial tissue, the superficial target area is caused by the existence of the dose build-up. The radiation dose is extremely uneven, which affects the effect of radiotherapy.
At this time, selecting a tissue compensator(bolus) of appropriate thickness and density to completely and seamlessly cover the surface of the superficial tissue can effectively improve the uniformity of the dose distribution in the superficial target area and improve the effectiveness of radiotherapy. The above is more professional. Simply put, the superficial tissue will receive more radiation dose after the surface is covered with tissue compensation，Improve curative effect.
The current mainstream material of tissue compensation(bolus) is composed of oil glue, and the patents are mainly in the hands of American companies.
Then, through communication between our company and the radiotherapy doctors of the Second Affiliated Hospital of Soochow University, we learned that the clinical requirement for compensation is that the density is equal to 1g/cm³, which is the same as the density of water.
As our company has many years of research experience on hydrogels and related products, based on experience and experimental data, we know that the density of most hydrogels is equal to or close to 1g/cm³.
As a result, our company organized public relations, Use existing hydrogel formulations。Developed a tissue compensation（bolus） product, and conducted relevant dosimetry tests, and obtained satisfactory results.
In terms of physical properties, hydrogels are similar to oil gels. However, the biggest advantage of hydrogels is the price. If you are interested in this product, please contact us.
