Dongguan Guyuan Chemical Co., Ltd. was established in 2017 and has established long-term and stable cooperative relationships with more than 100 domestic manufacturing enterprises. The company promotes high-purity nano silica powder and nano silica solution to the emerging field of nano silica application material manufacturing and processing, providing customers with high-quality products, stable sources of goods, and professional services.
The company has been established for more than nine years. Gu Yuan Company, in response to feedback from nano silicon application material enterprises on the application of nano silicon dioxide powder and nano silicon solution, has collaborated with the American Edenda Chemical Group to continuously conduct in-depth research and product optimization on nano silicon dioxide powder and nano silicon solution, and has set up factories in China for deep processing, manufacturing, and processing. The products processed by the company have excellent pe···
Dongguan Guyuan Chemical Co., Ltd. has been researching and producing nano silicon fireproof liquid since 2019. The fireproof liquid needs to meet the requirements of excellent fire resistance, radiation resistance, anti sagging, and frost resistance of the processed nano silicon fireproof glass. At the same time, the fireproof liquid needs to have a shelf life of not less than 6 months, during which the fireproof liquid will not solidify, deteriorate, or mold. The fireproof liquid has good fluidity after being prepared in the reaction kettle, and the processed glass does not have bubbles or turn white.
Due to the numerous "tunnel" shaped micropores and high melting point inside the gas phase silica, the fireproof glass adhesive layer begins to foam and expand when heated (with a foam expansion ratio of up to 10 times), absorbing the high heat brought by flame combustion and forming an opaque fireproof adhesive board. It has strong hardness and can effectively isolate the spread of flames, smoke, and toxic gases, as well as absorb the heat brought by flame combustion, thus playing a role in insulation.
Composite heat-insulating fire-resistant glass is a special type of heat-insulating glass composed of three or more pieces of float white glass with a multi glass and multi cavity structure. Nano silicon fire-resistant liquid adhesive is injected into the glass cavity, and the gas-phase silicon dioxide in the fire-resistant liquid couples with inorganic additives to form an inorganic transparent adhesive layer during high-temperature baking, thus meeting the corresponding fire resistance level requirements.

The silicon hydroxyl groups (Si OH) on the surface of gas-phase white carbon black can form physical or chemical bonds with the molecular chains of silicone rubber, forming an adsorption layer of "silica particles rubber molecules".
The primary particle size of fumed silica (fumed white carbon black) is between 7-80 nm, with a specific surface area of 50-380 m ²/g, and the surface is rich in silicon hydroxyl groups.

Gaseous silica is a type of primary nano silica particle with high sphericity, high purity, and narrow particle size distribution, which is formed by a precise ratio of hydrogen and oxygen gas and chlorosilane. It undergoes gas-phase oxidation and hydrolysis reaction in a high-temperature hydrogen oxygen flame at 1100-1800 ℃. The ultrafine amorphous silica produced is known as "industrial monosodium glutamate" due to its wide range of applications.
