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.

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.
