HPMC pulverbygningsklasse

HPMC-pulverbygningsklassen produceret af Milestone er produceret med bomuldsfibre af høj kvalitet, hvilket garanterer produktets høje kvalitet fra begyndelsen af ​​råmaterialet. En unik proces bruges i den efterfølgende behandling, og prøverne opbevares til test, når hver batch af produktionen er afsluttet for at sikre, at produktkvaliteten er kvalificeret.

Nedenfor introducerer vi et par enkle og direkte metoder, så alle let kan skelne, når de køber.

v Whiteness: Although the whiteness cannot determine whether HPMC pulverbygningsklasse is easy to use, and if some factories add whitener during the production process, it will also affect its quality. However, most good products have good whiteness.

v Fineness: The fineness of HPMC is generally 80 mesh and 100 mesh, and 120 mesh is less. Most of the HPMC pulverbygningsklasse produced by Milestones is 80-100 mesh. The finer the fineness, the better the quality in general.

v Transmittance: After putting HPMC pulverbygningsklasse in water to form a transparent colloid, look at its transmittance. The greater the transmittance, the better, indicating that there are less insolubles. The permeability of the vertical reactor is generally good, and the horizontal reactor is worse, but it does not mean that the quality of the vertical reactor is better than that of the horizontal reactor. The product quality is still determined by many factors.

v Proportion: The larger the proportion of HPMC pulverbygningsklasse, the heavier the better. The high specificity is generally due to the high hydroxypropyl content in it, and the higher the hydroxypropyl content, the better the water retention.

The HPMC pulverbygningsklasse produced by Milestone is produced with high-quality cotton fiber, which guarantees the high quality of the product from the beginning of the raw material. A unique process is used in the subsequent processing, and samples will be retained for testing after each batch of production is completed to ensure that the product quality is qualified.
