Anvendelser af hydroxypropylmethylcellulose

1. Belægningsindustrien: Det bruges som fortykningsmiddel, dispergeringsmiddel og stabilisator i belægningsindustrien og har god forenelighed i vand eller organiske opløsningsmidler. Som malingsfjerner.

2. Keramisk fremstillingsindustri: Det er meget brugt som bindemiddel til fremstilling af keramiske produkter.

7. Construction industry: As a water-retaining agent and retarder of cement mortar, it can make the mortar pumpable. I gips, gips, spartelpulver eller andre byggematerialer som bindemiddel for at forbedre smørbarheden og forlænge arbejdstiden. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water retention performance of hydroxypropyl methylcellulose HPMC prevents the slurry from cracking due to drying too fast after application, and enhances the strength after hardening.

8. Farmaceutisk industri: belægningsmaterialer; membran materialer; hastighedskontrollerende polymermaterialer til præparater med langvarig frigivelse; stabilisatorer; suspensionsmidler; klæbemidler til tabletter; viscosity-increasing agents

natur:

1. Udseende: hvidt eller råhvidt pulver.

2. Partikelstørrelse; the pass rate of 100 mesh is greater than 98.5%; beståelsesraten på 80 mesh er 100%. Particle size of special specifications is 40~60 mesh.

3. Karboniseringstemperatur: 280-300 ℃

4. Tilsyneladende massefylde: 0,25-0,70 g/cm (normalt omkring 0,5 g/cm), specifik vægtfylde 1,26-1,31.

5. Misfarvningstemperatur: 190-200 ℃

6. Overfladespænding: 2% vandig opløsning er 42-56dyn/cm.

7. Solubility: Soluble in water and some solvents, such as ethanol/water, propanol/water, etc. in appropriate proportions. Aqueous solutions are surface active. High transparency, stable performance, different specifications of products have different gel temperatures, solubility changes with viscosity, the lower the viscosity, the greater the solubility, different specifications of HPMC have certain differences in performance, and the dissolution of HPMC in water is not affected ved pH.
