I-Hydroxypropyl methylcelluloseiyimpahla eluhlaza esetshenziswa kakhulu. Ikakhulukazi ekusetshenzisweni kwe-putty powder. Ziningi izinto zomkhiqizo ezifana nalezi: ukumelana nosawoti, umsebenzi ongaphezulu, i-gelation eshisayo, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukunamathela, njll. Nokho, i-hydroxypropyl methylcellulose nayo ijwayele ukuba nezinkinga ezithile. Kunezizathu ezintathu zezinkinga:
1. Ukusetshenziswa kwe-hydroxypropyl methylcellulose
2, inani lezinto eziyisisekelo
3. Kuyinhlanganisela enengqondo yokugcwalisa ifomula
Isibonelo, imodeli ye-viscosity ye-hydroxypropyl methylcellulose isetshenziswa ngendlela engafanele, inani lezinto eziyisisekelo likhulu kakhulu, ukucoleka kokugcwalisa kuhle kakhulu, njll. kuze kube yilapho kuthathwa izinyathelo zokulawula ngezizathu ezithile, njengokusetshenziswa okufanele kwe-hydroxypropyl methylcellulose enemodeli ye-viscosity engu-100,000 Umkhiqizo, umthamo/idosi ye-3 kufanele ibe ngaphansi kuka-5 kg, umthamo/3. I-polyvinyl alcohol eyimpuphu akufanele ibe nkulu kakhulu, ingabi ngaphezu kuka-6%. I-filler fineness isebenzisa isigcwalisi esivamile se-325 mesh, futhi uma idlula i-600 mesh, ukusebenza kokwakha kuzothinteka kabi. Qaphela ukuthi lesi simo esingenhla kufanele sixazulule inkinga yokuklwebheka kweqoqo elibi.
