　　Guangxi Longhua nano calcium carbonate can improve the thixotropy of plastic masterbatches and improve formability. As a plastic filler, it has the effect of modification and reinforcement, improving the bending strength and bending elastic modulus, heat distortion temperature and dimensional stability of plastics, and also giving plastics hysteresis heat.

　　Guangxi Longhua nano calcium carbonate has excellent permeability, light transmittance, good gloss and excellent high drying properties in ink products.

　　Guangxi Longhua nano calcium carbonate is used as an ink filler in epoxy resin inks, with stable performance, high smoothness, and is not affected by the drying of packaging printing inks, and has strong adaptability.

　　Introduction

　　Guangxi Longhua nano calcium carbonate is a new type of ultrafine solid powder material established in the 1980s, with a particle size distribution between 0.01 and 0.1 μm. Due to the super optimization of nano calcium carbonate particles, its molecular structure and surface electronic structure have changed, forming quantum technology size effect, small size effect, surface effect and macroscopic quantum effect.

　　Production process

　　The production process of Guangxi Longhua nano calcium carbonate mainly uses the carbonization method, mainly including intermittent carbonization method, continuous sprayer carbonization method, and supergravity carbonization method.

　　The production process of Guangxi Longhua heavy calcium carbonate is usually crushing, ultrafine pulverization, grading and surface modification materials.

　　The production process of Guangxi Longhua active calcium carbonate generally uses dolomite as the main raw material, and is prepared by calcination, digestion, carbonization, separation, drying, grading, and packaging to obtain precipitated calcium carbonate products.

　　Typical application areas

　　Guangxi Longhua nano calcium carbonate has a 50-year application history overseas and is widely used in plastics, papermaking, building materials, inks, architectural coatings, sealants and adhesives.

　　Plastics

　　Key application areas: PVC profiles, pipes, cables, cable sheathing granules; PVC plastic film (calendered film) production, shoe factory manufacturing (such as PVC soles and decorative patches), etc. Suitable for engineering plastics, PP, PE, PA, PC, etc.

　　Application characteristics: Due to the lipophilic and hydrophilic properties of active nano calcium carbonate, it has good compatibility with epoxy resin, and can effectively improve or adjust the rigidity, ductility, smoothness and bending strength of products; improve processing performance, improve product rheological properties, dimensional stability, and high temperature resistance. It has the functions of filling and improving modification, and can replace some expensive fillers and auxiliaries, reduce the amount of epoxy resin used, thereby reducing product costs and enhancing competitiveness.

　　Nano calcium carbonate has a three-dimensional spatial structure and good permeability in rubber, and has a good semi-reinforcement effect.

　　Application fields: natural rubber, nitrile rubber, styrene-butadiene rubber, and compounded rubber, suitable for tires, rubber hoses, tapes, and skeleton seals, automotive parts and other rubber and plastic products.

　　Application characteristics: Nano calcium carbonate treated with surface modification materials has good compatibility with plastics, with the functions of reinforcement, filling, coloring, and improving the performance of processed products. It can make plastics easy to mix and disperse, the collagen fibers after mixing are soft, the surface of the plastics is smooth, and the ductility, tensile strength, and tensile strength of the products can be substantially improved. It can reduce the rubber content or partially replace more expensive white fillers such as polyethylene wax and white carbon black, enhancing the competitiveness of new products.

　　Sealing adhesive materials

　　Application fields: silicone copper, polyflow, polyurethane materials, epoxy resins, etc.

　　Application characteristics: When used in sealing adhesives, it has good amphiphilicity with plastic particles, can accelerate the condensation reaction of the adhesive, greatly improve the compressibility of the system, improve dimensional stability, improve the mechanical properties of the adhesive, and the dosage is large, achieving the dual effects of filling and reinforcement. At the same time, it can make the surface of the plastic particles bright and delicate.

　　Architectural coatings

　　Nano calcium carbonate can be used as a pigment filler, with the characteristics of fineness, uniformity, high fineness, and good electro-optical properties. Nano calcium carbonate has a steric hindrance effect. In chemical coatings, it can make the relatively high-density lithopone float and prevent settlement. After chemical coating, the fineness of the paint layer is improved, the gloss is high, and the adhesion of the paint is not reduced. This characteristic has been widely used and promoted in the coatings industry.

　　Application fields: water-based and oil-based coatings.

　　Application characteristics: It greatly improves the compressibility of the system, significantly improves the adhesion, washability, and stain resistance of the coating, improves the surface smoothness of the strength, and has a good anti-settlement effect. Partially replace polyethylene wax to control costs.

　　Ink

　　Application fields: suitable for offset lithographic inks, gravure inks, etc.

　　Application characteristics: The ink configured with Guangdong nano calcium carbonate has good body and viscosity, so it has good printing performance, stable performance, fast drying and no reverse effect; due to the small particle size, the printed matter is smooth, the dots are clear, and the gloss of the ink can be improved, suitable for fast printing.

　　Papermaking industry

　　The papermaking industry is an industry with great development potential for Guangdong nano calcium carbonate.

　　Application areas: cigarette paper, recording paper, book page printing paper, high-finesse coated paper, and high-end sanitary napkins, pull-up pants, etc.

　　Application characteristics: In the paper industry, adding nano calcium carbonate can improve the bulk density, surface fineness, and water absorption capacity of printing paper, enhance the strength and fast packaging printability of coated paper, and adjust the burning rate of cigarette paper.

　　Other industries

　　Guangxi Longhua nano calcium carbonate is used in the feed industry as a calcium supplement to increase the calcium content of feed.

　　In skincare products, due to its high purity, fine fineness, and small particle size distribution, it can also partially replace polyethylene wax. Adding nano calcium carbonate to toothpaste can improve its extrusion performance.

　　In recent years, with the rapid development of the plastics, papermaking, building coatings, and ink industries, and the continuous improvement of product quality and national standards, nano calcium carbonate has been widely used in various industries to replace imported raw materials.
