Definition Of Resins

- May 18, 2018-

The relative molecular weight is uncertain but usually high, solid, medium solid, pseudo solid, and sometimes liquid organic matter at ambient temperature. With a softening or melting temperature range, under the external force has a tendency to flow, rupture is often shell-like. In a broad sense, a polymer or prepolymer used as a plastic base material. Generally insoluble in water, soluble in organic solvents.

According to the source can be divided into natural resins and synthetic resins, according to their different characteristics of processing behavior and thermoplastic resin and thermosetting resin points. Dowex resin is an inseparable homogeneous mixed-bed resin. Low ppb levels of silicon, boron, sodium, potassium, sulfate, chloride, zinc, iron, and aluminum ions are achieved using an non-renewable bed in the ultra pure water polishing process. This type of non-renewable bed can be used for 2-3 years before replacement. The UPW grade resin has a high ion conversion rate (95% min), excellent conductivity and TOC cleaning characteristics and Ultra strong compressive strength. Because it is mixed with homogeneous 360 micron cation resin and 590 micron anion resin, it keeps the high dynamic performance and high operation Exchange capacity.
