I-Hydroxypropyl methylcelluloseiyimpahla eluhlaza esetshenziswa kakhulu.Ikakhulukazi ekusetshenzisweni kwe-putty powder.Ziningi izici zomkhiqizo ezifana: 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 imodeli ye-viscosity yoMkhiqizo we-100,000, umthamo akufanele ube ngaphansi kuka-3.5 kg/ton, futhi umthamo we-polyvinyl alcohol oyimpuphu akufanele ube mkhulu kakhulu, ungabi 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 kweqoqwana okubi.
