In the past, whether it was domestic humidity control materials for cultural relics or museum humidity control materials industries, both domestic and foreign, used overseas brands of humidity control materials. Hengyuan's research achievements in humidity control materials highlight the competitiveness of domestic products.

For example, museum humidity control materials in the past, products from Artsorb in Japan and Prosorb in Germany were granular silica gel products that needed to be packaged in a bag or box. Placing them in display cabinets would also look out of place with the exhibits. Hengyuan museum humidity control sheets are in the form of paper sheets, do not take up extra space, and can be concealed in the display cabinet compartments.

Secondly, there is the cost-effectiveness. Although cultural relics are invaluable, the large-scale use of foreign products will result in huge cost inputs. Domestic substitution for imports allows museums to save a significant amount of budget.

In terms of environmental protection, Hengyuan's products are based on plant fibers and are environmentally friendly and biodegradable, causing no pollution to the environment. Foreign products are mainly silica gel materials; after use, silicon dioxide cannot be degraded and will also burden the environment.

In the application scenario of cultural relic storerooms, Hengyuan has even made humidity control products in the form of tiles, which are affixed to the walls or ceilings.

In the past, humidity control in storerooms was mainly done by Japanese brands. As an industry veteran with 40 years of research, Japan was the first to use humidity control building materials to reduce energy consumption in storerooms and keep the humidity fluctuation range small.

However, it is undeniable that, according to the storeroom standards of Japanese museums, not only are the construction requirements for museum humidity control panels strict, but the airtightness of the storeroom itself is also very high. However, old storerooms in Chinese museums usually do not have such good airtightness. In this case, the moisture capacity of Japanese museum humidity control panels is relatively low and does not achieve the ideal effect. The advantages of Hengyuan products are highlighted here: not only is the moisture capacity large, but the simple construction requirements are more suitable for the current conditions of Chinese museum storerooms.

Shen Yuehua said that, as a humidity control material, the most important performance is moisture capacity. Japanese products are composed of natural inorganic substances, so their moisture absorption and release capacity is very limited. Hengyuan's products add functional composite materials to a natural porous structure, resulting in a moisture capacity nearly four times that of natural materials. Of course, Shen Yuehua also said that, for porous structural substrates of the same material, the moisture capacity should be controlled within a certain range, not the higher the better, mainly depending on the water-locking capacity of the porous structure. Therefore, the combination of functional composite materials and substrates is also Shen Yuehua's core patented technology.

At the same time, in terms of performance, Hengyuan humidity control materials, due to the addition of functional composite materials, have a fast moisture absorption and release speed. Whether it is the initial "pre-adjustment" or the "dynamic equilibrium" process, Hengyuan products respond to humidity much faster than Japanese products and can quickly adjust the humidity in the storeroom to the target value.

“Japanese natural mineral materials require air conditioning for pre-adjustment. For example, if the storeroom needs to reach 50% humidity, air conditioning must first be installed and run for 7 days. After that, the air conditioning can be intermittently paused to maintain the humidity within a certain range. This balance is only broken if the door is opened or there is air exchange. However, Hengyuan products themselves can provide precise humidity, and coupled with the fast moisture absorption and release speed, under the premise that the temperature and humidity in the storeroom meet the standards, the air conditioning operating time is greatly shortened, saving museums a lot of electricity costs.”

Finally, in terms of construction and installation, Hengyuan materials are "tailored to local conditions." Shen Yuehua said that Hengyuan customizes different products for different scenarios. "We are a relatively vertically segmented industry, so the professional requirements are relatively high, and the products for different application scenarios are also different, and the benchmark products are also different."

In cultural relic display cabinets, Hengyuan provides paper-like humidity control products that can be placed in display cabinet drawers, while in storerooms, humidity control products can be affixed like tiles.

As Hengyuan's humidity control products become increasingly known in the market, in 2015, overseas merchants found Shen Yuehua online and requested customized precise humidity control formulas for the preservation of cigars and cannabis, thus opening up the overseas market for Hengyuan.

However, humidity control materials in the cultural relic industry and the tobacco industry are still quite different, and new markets mean new challenges. Cultural relics require that humidity control materials should not have volatile ions, so non-ionic composite formulas must be used; while tobacco, although it has the same humidity requirements, requires high moisture capacity and fast humidity response, so ionic composite formulas are preferred. Therefore, the selection of composite formulas based on market applications is also one of Shen Yuehua's core patented technologies.

Shen Yuehua said that after Hengyuan thoroughly researched the humidity control mechanism, every time it is applied to a new industry, it will choose the most suitable formula according to customer needs. "Our technological achievements lie in the research of the humidity control mechanisms of various substances, and then, after combining different humidity control mechanisms, we can meet different needs, that is, using functional composite materials to formulate various humidity formulas to achieve precise humidity. The composite materials include inorganic and polymeric materials."

From being unrecognized to having over 300 corporate users, humidity control will become a future rigid demand.

Hengyuan has developed for more than 20 years, and Shen Yuehua has been on the road of research and development. In the first ten years, Shen Yuehua focused on fiber desiccants. However, for the desiccant industry using silica gel, calcium chloride, and mineral soil as materials, paper-like desiccants were difficult to be accepted. "At the beginning, many people didn't accept it, saying: How can paper be a desiccant?" Shen Yuehua laughed, "At that time, there happened to be a niche area, blood glucose test strips in biological reagents, which had very small packaging. However, traditional granular desiccants would make the packaging very large, and Hengyuan's paper-like desiccants could be cut to any size. It was this slight difference in form that made the biological reagent niche market one of Hengyuan's main markets."

Shen Yuehua frankly admitted that he did less in market development and proactive sales. Currently, humidity control products are the second ten years of entrepreneurship. This time, humidity management has become a rigid demand in many industries.

With the improvement of quality standards in product packaging in various industries, enterprises have gradually realized that packaging is not enough to be only moisture-proof; it is also necessary to control the humidity range, which cannot be too dry or too humid. Therefore, the increase in market demand is the main reason why Hengyuan has the opportunity to grow rapidly.

Hengyuan has never stopped in research and development, and the market has gradually begun to release demand. "20 years ago, if you said biodegradable, the market might not understand, but today, biodegradable humidity control materials have become a rigid demand in many industries."

Shen Yuehua said that the value innovation of Hengyuan products has brought direct and indirect cost reduction and efficiency improvement to customers, which is the main reason for customers' continued cooperation over the years.

We served an art warehouse whose services to clients included storing collections on their behalf. Previously, maintaining optimal temperature and humidity 24/7 in the warehouse required running air conditioning around the clock. However, using Hengyuan's warehouse building materials, energy savings can be achieved through a cyclical model of running the air conditioning for only 4 hours a day, while still meeting temperature and humidity standards.

Hengyuan's products are easy to install, slightly cheaper than imported products, and offer excellent service, making them a preferred alternative for many museums and art galleries in the industry. "Japanese warehouse building materials are expensive, and museums don't use them much; instead, they rely heavily on air conditioning. Using our products allows museums to reduce the frequency of air conditioning use, thus achieving energy savings and cost reduction."
