Global coverage! 50Years' Silicone Sealant Durability Research Started in the USA!

  50 years durability test USA sample successfully!

This month, after guangzhou, turpan exposure test site, sealant 50 years durability test into the United States q-lab Florida and Arizona exposure test site.

Q-lab Florida and Arizona are internationally recognized benchmark outdoor exposure test sites.

Because of the harsh climate, products exposed to sunlight in these areas will undergo a faster degradation process.

Baiyun chemical will release 160 groups of silicone structure sealant samples in the two insolation sites, and set 16 sampling cycles, among which the shortest sampling cycle is half a year and the longest is 50 years.The sampling interval is short in the early aging stage and long in the late aging stage.

The Florida Testing Center

  The world's largest outdoor aging test center with high temperature and humidity.The test field located in the southernmost tip of the United States, 35 km away from Miami, was founded in 1931, now covers an area of 24 hectares, is the area and the largest in the world now proving ground, a subtropical hot and humid environment, the test field sunlight irradiation intensity big, strong ultraviolet ray, a year the amount of sunlight irradiation is elsewhere for several times, sun products is also in other parts of the aging speed of several times.

At the same time, high temperature, abundant rainfall and high humidity all year round also accelerate the aging of sun-exposed products.

It is this combination of strong uv light, high humidity and high temperature that makes the Miami tanning test site an ideal place to test materials for corrosion resistance and durability in an outdoor environment.

This sunny, wet and warm extreme climate has proved particularly effective for the following types of tests, including:

•Color change, fading, and loss of luster

•cracking, peeling, pulverizing and foaming

•mechanical strength loss and physical degradation

•humidity sensitive products such as coatings, building materials, and some plastics

•biodegradation, including mildews, molds, fungi, and algae

        •accelerated corrosion testing

 

The Arizona Testing Center

The largest desert sun exposure center in the world.

The test site was built in 1948 on the edge of the desert in the Midwest, 50km north of phoenix. Its climate is characterized by abundant sunshine, little rain and high temperature, which is very suitable for the aging test of polymer materials.

In summer, temperatures can reach 115 degrees Fahrenheit (46°C).

Black insolated samples can reach more than 160 degrees Fahrenheit (71°C).

It's this combination of strong ultraviolet light and extreme temperatures that makes Arizona an ideal place to test the aging properties of highly durable materials.

This extreme climate has proved particularly effective for the following types of tests and materials, including:

•physical degradation of plastics and mechanical loss of strength

•thermal expansion effect and thermal expansion coefficient do not match

•maximum service temperature studies

•color change, fading and fading

•cracking, deformation and thermal aging

 

An exposure field is a place where exposure tests are carried out.

Exposure should be equipped with exposure rack, meteorological measurement of the basic instruments, meters, etc.

The natural climate environment is ever-changing and durabilityed by geographical location. Therefore, it is very important to choose the natural climate exposure test site.

Natural climate experiments are influenced by regional climates.

Internationally, these climates are classified into five major categories: hot and humid, hot and dry, moderate, mild and cold.

Exposure sites should be chosen to represent the harshest climate type or approximate actual environmental conditions.

The successful sample casting at the Florida and Arizona insolation bases marks the completion of the 50-year durability test of sealant, and the comprehensive coverage of the east-west hemisphere, hot and humid and hot climate test!

Baiyun chemical natural aging exposure research work in the forefront of the industry!

 

As a modern enterprise with a history of more than 30 years in the domestic sealant industry, Baiyun chemical has been standing at the height of the industry, paying attention to the safety application of structural sealant with a strong sense of responsibility, and has carried out a series of accelerated and natural aging exposure tests of silicone structural sealant.

In 1997, Baiyun chemical co., ltd. built a physical curtain wall in the company square that was planned to be exposed to sunlight for 50 years.

In 2012, Baiyun chemical co., LTD., together with the aging research institute of guangzhou institute of synthetic materials co., LTD., started the sealant exposure experiment in two extreme climate zones in guangzhou and turpan, xinjiang simultaneously.

In September 2013, the 50-year durability test of guangzhou and turpan insolation base welcomed the expert test.

In March 2014, the "silicone structure sealant natural exposure test data accumulation and aging prevention research" project group was established, which was composed of the core technical backbone of Baiyun institute of chemical industry and aging research.

On September 25, 2014, the physical curtain wall of turpan was completed.

On June 30, 2016, the exposed curtain wall was completed in guangzhou.

From June to August, 2017, Baiyun chemical company conducted system technology return visit for the existing curtain wall over 10 years.

Covering more than 50 building curtain walls in Beijing, guangzhou, shenzhen, chongqing, Qingdao, xichang, shenyang and other places.

In September 2017, samples were successfully sent to the tanning bases in Florida and Arizona.

 

  Under different environment, atmospheric environment of natural aging test data, not only will continuously research and development for the enterprise innovation and guide the product in different climate conditions applied research to provide powerful data support, also let the white clouds chemical industry to provide customers with more secure, more permanent high quality silicone sealant structure, the standard of the industry, national and international standards to provide more reliable, scientific and reliable basis.
