Once the polymer has been dried into a powder, it undergoes milling and classification. Milling helps to achieve a uniform particle size distribution, which is essential for the application performance of RDP. The powder is then classified using air classifiers to separate fine particles from larger ones, ensuring that the final product meets the required specifications.
Hydroxyethylcellulose (HEC) er et ikke-ionisk, vandopløseligt polymer, der anvendes bredt inden for mange industrier, herunder fødevareproduktion, farmaceutiske produkter, byggeri, og personlige plejeprodukter
. Dets egenskaber som fortykningsmiddel, stabilisator og emulsionsmiddel gør HEC til et værdifuldt produkt. Fremstillingsprocessen for HEC indebærer flere trin, der sikrer, at det endelige produkt har de ønskede fysiske og kemiske egenskaber.RDPs also play a crucial role in enhancing the durability of construction materials. By improving the interfacial adhesion between aggregates and the polymer matrix, RDPs can reduce the risk of cracking and improve resistance to mechanical stress. This attribute is particularly beneficial in locations where composite materials are exposed to harsh environmental conditions or sustained heavy loads.
