Kodi cellulose ndi chiyani?
Cellulose edders ndi ma poity osungunuka madzi kuchokera ku cellulose, olima owonjezera achilengedwe, omwe ali ndi zotsatira zowonjezera, nthawi yayitali, nthawi yotsekemera, nthawi yayitali yotseguka, etc.
Cellulose ether
Ogawidwa mu hpmc (hydroxypropylmethylcelulose), hemc (hydroxyellulose) ndi hec (hydroxyethllulose), ogawika kalasi yosinthidwa.
Chifukwa chiyani cellulose ether gawo la khoma la khoma?
Pamakoma detulty, cellulose ether ndi chowonjezera cha magwiridwe antchito, ndipo putty yowonjezera yowonjezeredwa ndi ethel ether ether ether amatha kupereka khoma losalala. Zimathandiza kusanthula kosavuta, moyo wautali, kusunga madzi abwino kwambiri, ndi zina zambiri.
