About Us
Xi'an Meinan Biotechnology Co.,Ltd.
Xi'an Meinam Biotechnology Co., Ltd. (hereinafter referred to as "Maenam High-Tech"), a national high-tech enterprise and a Class A reserve listed company in Shaanxi Province, is committed to continuous innovation and development. By integrating cutting-edge global technologies, the company has achieved remarkable accomplishments in the field of new materials. It researches and develops novel green eco-composite materials, focusing on two major directions: waterproofing and water retention. These materials are applied in areas such as structural self-waterproofing and desert ecological restoration, promoting green transformation and the development of desert carbon sink cycles.
The Phase I plant of Maenam High-Tech commenced production in October 2023, with an annual output value of approximately 200 million yuan. Meanwhile, the Phase II plant expansion project was officially signed between the Xixian New Area Airport New City and Maenam High-Tech on April 3, 2025, with a total investment of 1 billion yuan. Construction officially commenced on August 17, 2025. According to the plan, upon full production, the project will have an annual capacity of 120,000 tons and an annual output value exceeding 2.5 billion yuan. It is expected to create over 100 jobs, injecting new momentum into regional industrial upgrading and employment growth. The facility is set to become one of the largest green eco-friendly new material manufacturing bases in China.

Technical principle
Microparticle waterproof new material series products
Microparticle waterproof new material series products are 10-2 ~ 10 microns of three-mesh glass ceramic material containing micrograins formed by silicon dioxide after microwave special nucleation treatment. Combined with the excited aerogel reaction, it has a hard texture, high softening point and mechanical strength, and has good chemical stability and thermal stability. It has fundamentally changed the construction technology of traditional construction industry from qualitative degeneration.
Micro-particle water retention new material series products are the reverse research and development of micro-particle waterproof technology, tungsten trioxide polyaniline graphene composite material formed by inorganic minerals and plant extracts, can absorb more than 600-1000 times its own weight water.
Key technology
Microparticle waterproof new material series products
Plant extraction technique in "A method for extracting tannin from lacquer leaves". Active chemicals can be extracted from cotton. The raw materials required for the product are very common, easy to directly obtain and the cost is low, which greatly reduces the research and development cost of GT micro-particle waterproof new material technology and the production cost of its series products.
Technological innovation point
Microparticle waterproof new material series products
(1) The use of plant extraction process, the use of plants and non-metallic minerals as raw materials, made through physical methods, raw material costs are only equivalent to 50%-60% of traditional petroleum-based materials, greatly reducing manufacturing costs;
(2) At the same time, no waste water, waste gas, waste residue discharge in the production process, in line with green and low-carbon environmental protection requirements;
(3) Strong stability, can maintain a stable waterproof effect in the temperature range of -50℃ to 250℃;
(4) Strong water retention ability, tungsten trioxide polyaniline graphene composite material formed by inorganic minerals and plant extracts can absorb more than 600-1000 times its own weight of water;
(5) Through special technical treatment, the sand is breathable and waterproof, preventing water infiltration, while storing water and improving the surface sand body.
(6) The use of high temperature pressure physical method, so that the particle powder attached to the surface of the sand, forming a membrane structure, to achieve waterproof effect, while improving the stability of the sand body, air permeability and water retention.
