Nano Calcium Carbonate , Nano Precipitated Calcium Carbonate , Nano CaCO3 NCC-602 for adhesive
Application of Nano Calcium Carbonate NCC-602:
Nano calcium carbonate NCC-602 is mainly used in silicone, coverging, polyurethane, epoxy and other sealed structural adhesive.
Characters of Nano Calcium Carbonate NCC-602:
Nano calcium carbonate NCC-602 for sealant uses a unique surface treatment technology, a special surface activation treatment. It has complete cubic crystal structure, with smaller particle size and high specific surface area and good dispersibility, with nanometer particle size effect, surface effect and small can significantly improve the tensile fracture strength of the product, the elongation and the cohesive force, and has high elastic recovery rate. Good dispersion, good processing performance.
Nano calcium carbonate NCC-602 gives the adhesive good reinforcing, bonding, flow and thixotropic properties. It also make the adhesive has high tensile strength, high elongation, good adhesion good thixotropy.
Difference of Nano Calcium Carbonate and heavy calcium carbonate:
The production process of nanometer calcium carbonate mainly uses carbonization method, which is mainly composed of intermittent carbonization method, continuous spraying carbonization method and supergravity carbonization method, whose particle size is between 10-100nm.
The production process of heavy calcium carbonate is mainly crushing, ultrafine crushing, grading and surface modification.
e.he main defference bewteen them is the particle size.
Nano calcium current modifier according to its structure and properties can be divided into surface active agent, coupling agent, polymer and inorganic substances, mainly in order to give full play to the nano effect of nanometer calcium carbonate improve its dispersion in the composites, enhanced with the affinity of the organism, improve the performance of the nano calcium carbonate filler materials, must adopt effective modification technology and surface modification methods for the surface modification, and then expanding to broaden its application domain,
Nanometer calcium carbonate has been used for 50 years in foreign countries. It is widely used in rubber, plastic, paper, chemical building materials, ink, coating, sealant and adhesives.
