Qonda Izindlela Ezintathu Zokuqedwa Kwe-HPMC

I-Hydroxypropyl Methyl Cellulose (HPMC)kuyintoi-cellulose ether eguquguqukayoisetshenziswa kakhulu ekwakhiweni, emithini yemithi, ezimonyweni, nasezimbonini zokudla. Ukusebenza kwayo kahle ekwakhiweni kuncike kakhulu ku-ukuthi incibilikiswa kanjani, njengoba ukuqedwa kuthinta:

  • Ukuvumelana kwe-viscosity
  • I-Rheology
  • Ukwakheka kwamafilimu
