The objective of this work is the preparation and the characterization of high density polyethylene /calcium carbonate (HDPE/CaCO3) composites. Polyethylene composites, containing 10-35 wt. % of CaCO3 and HDPE with MFI (Melt Flow index) (0.550 g/10mn) were prepared with co-extrusion process using extruder type Cincinati 90D. Thermal and…
Calcium carbonate (CaCO3) was used as a filler in the mixture for plastic pipes to improve the mechanical properties of the product, this research dealt with the study of the effect of increasing the proportion of calcium carbonate (CaCO3) on the properties of the produced pipe through a…
The effects of filler content, filler particle size and surface coating, as well as the natures of the wax and metal stearate lubricants on the properties of calcium carbonate-filled linear low-density polyethylene compounds were investigated. The elongation at break decreased exponentially with filler loading irrespective of whether the…
CaCo3 – Calcium Carbonate is added in the PVC blend to improve the mechanical properties such as tensile strength, elongation, and impact strength of the profile. What is uPVC ? Unplasticised Polyvinyl Chloride (uPVC) uPVC a low-maintenance building material used as a substitute for Steel, Aluminium or Wood…
The dewatering of large amount of industry sludge is one of the significant environmental problems in the pulp and paper industry. Calcium carbonate fillers are an important component in primary sludge from paper mills. In this paper, the role of precipitated calcium carbonate (PCC) on the dewaterability of…
Vietnam exports of Carbonates; calcium carbonate was $1,736.67K and quantity 5,151,360Kg. Vietnam exported Carbonates; calcium carbonate to Bangladesh ($428.64K , 1,271,450 Kg), India ($374.46K , 1,110,730 Kg), Myanmar ($154.37K , 457,902 Kg), Singapore ($123.32K , 365,791 Kg), Cambodia ($102.08K , 302,789 Kg). Carbonates; calcium carbonate imports by country…
Calcium carbonate in Vietnam are considered as chemically inert materials. Therefore, they are widely considered in the field of biosensing, drug delivery, and as filler material in plastic, paper, paint, sealant, and adhesive industries. The unusual properties of Vientma calcium carbonate-based nanomaterials, such as biocompatibility, high surface-to-volume ratio,…
Calcium carbonate in Vietnam is the predominant filler used in polyvinyl chloride compounding. Selection of fillers, as in the case with other compounding ingredients, involves consideration of available types and their effects on processing, product properties, and economics. In this article the effect of the particle size of…
Calcium carbonate powder is one of the most popular and essential mineral fillers used in the plastic industry for various purposes. As an important element in plastic compounds, CaCO3 helps decrease surface energy and provides opacity and surface gloss, which improves the surface finish of the products. Calcium…
