Tšusumetso ea HPMC Viscosity le Fineness ka Mortar Performance

Viscosity le fineness ea Hydroxypropyl Methylcellulose (HPMC) e ka susumetsa haholo ts'ebetso ea seretse. Mona ke kamoo paramente e 'ngoe le e' ngoe e ka amang ts'ebetso ea seretse:

1. Viscosity:
   • Poloko ea Metsi: Limaraka tse phahameng tsa viscosity HPMC li na le ho boloka metsi a mangata motsoakong oa seretse. Ts'ebetso ena e ntlafalitsoeng ea ho boloka metsi e ka ntlafatsa ts'ebetso, ea eketsa nako e bulehileng, 'me ea fokotsa kotsi ea ho omisa pele ho nako, e leng molemo ka ho khetheha maemong a chesang le a omileng.
   • Ntlafatso ea Khomarelo: HPMC e nang le viscosity e phahameng e theha filimi e teteaneng le e momahaneng holim'a likaroloana, e lebisang ntlafatsong ea ho khomarela lipakeng tsa likarolo tsa seretse, joalo ka li-aggregates le li-binders. Sena se fella ka matla a matla a tlamahano le ho fokotsa kotsi ea delamination.
   • Phokotso ea ho Sagging: Viscosity e phahameng ea HPMC e thusa ho fokotsa tšekamelo ea seretse ho thella kapa ho thella ha se sebelisoa ka holimo. Sena se bohlokoa haholo lits'ebetsong tse holimo kapa tse otlolohileng moo seretse se hlokang ho boloka sebopeho sa sona le ho khomarela substrate.
   • Matla a Ntlafetseng a ho sebetsa: HPMC e nang le viscosity e nepahetseng e fana ka thepa e lakatsehang ea rheological ho seretse, e lumellang ho kopanya habonolo, ho pompa le ho sebetsa. E ntlafatsa ho ata le ho momahana ha seretse, ho nolofaletsa ho kopanya hantle le ho qeta.
   • Tšusumetso ho Likahare tsa Moea: HPMC e nang le viscosity e phahameng haholo e ka sitisa moea o kenang motsoakong oa seretse, 'me ea ama le ho tšoarella ha eona. Ka hona, ho bohlokoa ho leka-lekanya viscosity le lisebelisoa tse ling ho netefatsa hore moea o kenella hantle.
2. Fineness:
   • Phatlalatso ea Particle: Likaroloana tse ntle tsa HPMC li atisa ho hasana ka mokhoa o ts'oanang ka har'a matrix a seretse, e leng se lebisang ho ntlafatsoe kabong le katlehong ea polymer ho pholletsa le motsoako. Sena se fella ka litšobotsi tsa ts'ebetso tse tsitsitseng, tse kang ho boloka metsi le ho khomarela.
   • Kotsi e Fokotseng ea ho Balling: Likaroloana tse Finer HPMC li na le mekhoa e metle ea ho kolobisa 'me ha li na tloaelo ea ho etsa li-agglomerate kapa "libolo" motsoakong oa seretse. Sena se fokotsa kotsi ea ho ajoa ka tsela e sa leka-lekaneng mme se netefatsa hydration e nepahetseng le ts'ebetso ea polymer.
   • Surface Smoothness: Finer HPMC particles kenya letsoho hore ho be le seretse se boreleli, ho fokotsa monyetla oa ho ba le bokooa ba holim'a metsi joalo ka liphahlo kapa mapetsong. Sena se ntlafatsa ponahalo ea botle ba sehlahisoa se felileng mme se ntlafatsa boleng ba kakaretso.
   • Ho lumellana le Li-additives tse ling: Likaroloana tsa Finer HPMC li lumellana haholoanyane le li-additives tse ling tse atisang ho sebelisoa ha ho etsoa lihlahisoa tsa seretse, joalo ka thepa ea samente, li-admixtures le li-pigments. Sena se lumella ho kenyelletsa habonolo le ho netefatsa homogeneity ea motsoako.

Ka kakaretso, viscosity le botle ba HPMC li bapala karolo ea bohlokoa ho khetholla ts'ebetso ea seretse. Khetho e nepahetseng le ntlafatso ea liparamente tsena li ka lebisa ts'ebetsong e ntlafalitsoeng, ho khomarela, ho hanyetsa sag, le boleng ba kakaretso ba seretse. Ho bohlokoa ho nahana ka litlhoko le maemo a ikhethileng ha u khetha kereiti e nepahetseng ea HPMC bakeng sa sebopeho se fanoeng sa seretse.
