Delta Tecnic是一家位于巴塞罗那的公司，专门针对塑料，电缆，油墨，油漆和化妆品的颜色浓缩物和原材料生产和分配，可促进MicromasterBatches的生产，以改善PVC和电缆行业的稀释过程。通过这种创新的解决方案，制造商可以优化其生产过程，从而在最终结果中实现更高的质量并降低成本。
The micromasterbatch is a type of masterbatch with a reduced pellet size, applicable in both PVC and polyolefins, which provides better control and optimal color homogeneity. A key bet in the sector in order to make cable manufacturing cheaper, speed up production, gain efficiency and guarantee the highest possible quality. And the fact is that the reduced size of the Delta Tecnic masterbatch ensures a faster dilution, as they melt and incorporate the compound earlier.
During the masterbatch extrusion process, the pigments, i.e. the raw material, are dispersed. Originally, the pigments have agglomerates in their structure, which are separated in this process into crystalline units and then encapsulated in a polymeric base. After encapsulation of the single units, the pellet is formed and prevented from re-agglomerating, avoiding impurities or sparks in the final product. Delta Tecnic ensures the best dispersion and optimal dilution in the extrusion process with maximum coloring strength.
The company promotes from its Delta Color division a series of micromasterbatch solutions developed for all types of applications in the cable sector and the PVC industry. As novelties, the following stand out:
Micropellet.PVC-based masterbatch for all types of applications in the PVC and cable industry, developed to improve dilution in the compound.
Small Micropellet.电缆制造和PVC行业中所有类型应用的颜色万事集，需要快速稀释和良好的同质性。粒径比标准颗粒小三倍，它可以保证颜色同质性而不会污染灰尘。
Micro Bead.PE and EVA based masterbatch for the cable industry, it allows to improve color dilution where traditional masterbatches do not achieve good color homogenization. Its reduced design improves dosing compared to traditional granules. This masterbatch formulation helps to eliminate defects or areas of uneven color in cable manufacturing.
Dilution is the process by which the masterbatch is incorporated into the compound for the transformation of the plastic. The factors that influence the quality of the dilution are diverse, including the formulation and the size of the pellet of the masterbatch. From Delta Tecnic, the objective is to provide a masterbatch that ensures the fastest possible dilution.
For a better process result, a proper dosing must also be performed. Thanks to the excellent selection of our pellet size regularity the dosing of our masterbatches is done in an optimal way, without causing problems during their entry into the extrusion process. In many cases a mixing unit in the dosing system can help to improve the homogeneous distribution of small pellets in relation to large pellets. When all this mixture is discharged into the extruder, the homogenization of the final color of the manufactured part is optimized.
越来越短，更快的挤出机的趋势会产生隔热层壁厚较小的电缆，这使得获得完美的颜色同质性变得更加困难。因此，由于新的尺寸减小了颗粒主斑，因此在颜色均匀性方面改善结果更加容易。
