Uses and properties of silica

Silica has a wide range of uses, and different products have different uses. Used as a good reinforcing agent for synthetic rubber, its reinforcing performance is second only to carbon black, and even better than carbon black after ultra-fine and proper surface treatment. To Silica is added to the resin to improve the moisture-proof and insulating properties of the resin. Filling in plastic products can increase slip resistance and oil resistance. Filled with silicone resin, it can be made into plastic with resistance above 200℃. To Silica can be used as a filler in polyethylene, polypropylene, polybutene, epoxy resin and other plastics, which can improve the elastic strength and wear resistance of the plastic, as well as the thermal stability of hardness. Silica used in cables can also improve the electrical insulation of cables. For example, methyl vinyl silicone rubber high-voltage wires need to use fumed silica or high-quality precipitated silica. It is often difficult to separate the two layers of plastic film, and the bag opening is difficult to open when bagging, so silica is a very popular opening agent. In the production of rubber shoes, people not only require fastness to rubber shoes, rain boots, sports shoes, travel shoes, fitness shoes, ballet shoes, etc., but also require beautiful colors, comfort and lightness. Silica not only has good reinforcement, abrasion resistance, slip resistance and upper adhesion, but also a good light-colored reinforcement material. Therefore, it plays an important role in the development of rubber shoes to provide the quality and style of shoes. Important role. To Silica is used in adhesives made of natural rubber or synthetic rubber to provide thixotropy and reinforcement. At the same time, it can also improve adhesion due to its stretchability, which is high in quality and low in price. Silica can also be used in some products to improve free flow, such as grass fertilizers, fungicides, laundry bleach, phenol and urea plastic products, rubber sulphur and anti-caking mixtures.

Application of heavy calcium in ten major industries

Heavy calcium carbonate is usually used as a filler. It is also widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. The agent can increase the volume of the product and reduce the production cost. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber. ... 1. Heavy calcium powder used in the rubber industry. Heavy calcium carbonate powder for rubber: 400 mesh, whiteness: 93%, calcium carbonate: 96%) Calcium carbonate is one of the largest fillers used in the rubber industry. A large amount of calcium carbonate is filled in rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing costs. Filling calcium carbonate in rubber can obtain higher tensile strength and tearing strength than pure rubber vulcanizates. Crack strength and abrasion resistance. ... 2. Heavy calcium powder used in the plastic industry Plastic-heavy calcium carbonate powder (heavy calcium powder) 400 mesh for plastic masterbatch and color masterbatch, requiring high whiteness after heating, the ore structure is large crystalline calcite, calcium carbonate content : 99%, whiteness: 95%), calcium carbonate can play a role as a skeleton in plastic products, and has a great effect on the dimensional stability of plastic products. It can also increase the hardness of the products and improve the surface gloss of the products. And surface smoothness. Because the whiteness of calcium carbonate is above 90, it can also replace expensive white pigments. To To 3. Heavy calcium powder used in the paint industry Paint-heavy calcium carbonate (heavy calcium powder) 800 mesh or 1000 mesh for latex paint, whiteness: 95%, calcium carbonate: 96%) The amount of calcium carbonate in the paint industry is also relatively high. Large, for example, the amount used in thick paint is more than 30%. To 4. Heavy calcium powder for water-based paint industry Heavy calcium carbonate (heavy calcium powder) for water-based paint 800 mesh or 1000 mesh, whiteness: 95%, calcium carbonate: 96%, calcium carbonate is more useful in the water-based paint industry Wide, can make the coating non-sedimentation, easy to disperse, good gloss and other characteristics, and the amount of water-based coatings is 20-60%. To 5. Heavy calcium powder for paper industry Heavy calcium carbonate (heavy calcium powder) for papermaking: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98%. Calcium carbonate plays an important role in the paper industry. It can ensure the strength of paper. Harmony and whiteness, and the cost is low. 6.325 mesh, whiteness requirement: 95%, calcium carbonate content: 98%) Calcium carbonate plays an important role in the concrete in the construction industry.

How calcium carbonate improves HDPE performance

Calcium carbonate has many advantages such as easily available raw materials, low price, good stability, and non-toxicity. When used for filling HDPE, it can not only reduce material costs, but also increase toughness and reinforcement, improve material impact strength, and improve material elastic modulus. Tensile performance has become one of the most important filling materials for HDPE. 1. Coupling agent activated calcium carbonate modified HDPE: the interaction between micron calcium carbonate treated with coupling agent and polymer segments can slow down or limit the movement between segments, so that the silver streak of the composite material can reduce the impact toughness improve. Adding 2% silane coupling agent to activate nano-CaCO3 in recycled HDPE can significantly improve the tensile, bending, and impact properties of the modified resin, approaching or even reaching the level of engineering plastics. 2. Organic matter activated calcium carbonate modified HDPE: Common organic matter used to modify calcium carbonate powder includes fatty acids (salts), stearic acid, etc. Using fatty acid to treat CaCO3 for filling modified regenerated HDPE, the melting point, tensile stress and impact strength of composite materials are significantly improved compared with HDPE. Treating CaCO3 with stearic acid to modify HDPE found that the composite material can maintain higher impact toughness and elongation at break at lower temperatures. This is mainly due to the nucleation effect of CaCO3 that reduces the spherulites of the material. The formation of the size improves the Young's modulus and yield strength of the material. 3. Polymer activated calcium carbonate modified regenerated HDPE: Polymer surface treatment can be divided into reactive cellulose surface treatment and graft polymer surface treatment. Through interface modification, a ternary composite material (regenerated HDPE/POE/CaCO3) with CaCO3 as the core and maleic anhydride grafted ethylene-octene copolymer elastomer (POE) as the shell is prepared, due to the "core-shell" structure The formation of the elastomer and CaCO3 show a synergistic toughening effect. Compared with the untreated CaCO3 composite material, at the same CaCO3 content, the surface treated CaCO3 forms a stronger interfacial adhesion with the elastomer. As a result, the "brittle-to-tough" transition of the ternary composite material occurs at a lower elastomer content. The nano-calcium carbonate activated by surfactants improves the performance of the composite material due to the improvement of dispersibility and the strengthening of the entanglement with the HDPE matrix. The unactivated nano-calcium carbonate is prone to agglomeration. As a stress point in HDPE, it will reduce the performance of the composite material.
