Hydroxypropyl methylcelluloseke thepa e tala e sebelisoang haholo. Haholo-holo tšebelisong ea phofo ea putty. Ho na le litšobotsi tse ngata tsa sehlahisoa tse kang: ho hanyetsa letsoai, ts'ebetso ea bokaholimo, gelation ea mocheso, botsitso ba PH, ho boloka metsi, ho khomarela, jj. Leha ho le joalo, hydroxypropyl methylcellulose le eona e na le mathata a mang. Ho na le mabaka a mararo a mathata:
1. Tšebeliso ea hydroxypropyl methylcellulose
2, ke bongata ba thepa ea motheo
3. Ke motsoako o utloahalang oa li-fillers ka mokhoa o loketseng
Mohlala, mohlala wa viscosity wa hydroxypropyl methylcellulose o sebediswa ka tsela e sa lokelang, bongata ba thepa ya motheo bo bongata haholo, botenya ba filler bo botenya haholo, jj. ho fihlela mehato ya taolo e nkuwa ka mabaka a itseng, jwalo ka tshebediso e nepahetseng ya hydroxypropyl methylcellulose ka mohlala wa viscosity wa Sehlahiswa sa 100,000, tekanyo ha ea lokela ho ba ka tlase ho 3.5 kg/ton, mme tekanyo ya phofo ya polyvinyl alcohol ha ea lokela ho ba kgolo haholo, e seng ho feta 6%. Botenya ba filler hangata bo sebedisa filler e tlwaelehileng ya mesh ya 325, mme ha e feta mesh ya 600, tshebetso ya kaho e tla ameha hampe. Hlokomela hore boemo bo ka hodimo bo lokela ho rarolla bothata ba ho qhaqha ha batch hampe.
