Mesebetsi ea HPMC/HEC ho Thepa ea Mohaho

Hydroxypropyl methylcellulose (HPMC) le Hydroxyethyl cellulose (HEC) ka bobeli ke li-cellulose ethers tse sebelisoang hangata indastering ea kaho ka lebaka la thepa ea tsona e fapaneng ea ts'ebetso. Mona ke e meng ea mesebetsi ea HPMC/HEC thepa ea moaho:

1. Ho boloka metsi: HPMC / HEC e ka boloka metsi ka thepa ea mohaho, ho ntlafatsa ts'ebetso ea bona le ho fokotsa kotsi ea ho phunyeha le ho fokotseha. Li etsa filimi e tšesaane ho pota-potile likaroloana tsa samente, tse fokotsang ho tsoa ha metsi mouoane nakong ea ho folisa.
2. Ho teteana: HPMC/HEC e ka tenya lisebelisoa tsa moaho, ea ntlafatsa thepa ea bona ea rheological le ho ntlafatsa ho khomarela. Li eketsa viscosity ea motsoako, ho fokotsa kotsi ea ho theoha le ho rotha.
3. Tlamo: HPMC/HEC e ka sebetsa e le setlamo sa thepa ea moaho, ea ntlafatsa matla a eona a mochini le botsitso. Ba theha maqhama a matla le likaroloana tsa samente, ho matlafatsa momahano oa motsoako.
4. Tšireletso ea bokaholimo: HPMC/HEC e ka sireletsa bokaholimo ba thepa ea moaho ho tsoa linthong tsa tikoloho joalo ka mongobo, mahlaseli a kotsi a UV, le ho pepesehela lik'hemik'hale. Ba etsa filimi e tšesaane holim'a lintho tse bonahalang, ho fokotsa kotsi ea ho senyeha le ho ntlafatsa ho tšoarella ha thepa.
5. Lubrication: HPMC/HEC e ka sebetsa joalo ka setlolo linthong tsa moaho, ea ntlafatsa thepa ea bona ea phallo le ho fokotsa kotsi ea ho putlama le ho arohana. Ba fokotsa khohlano pakeng tsa likaroloana tsa samente, ho matlafatsa ts'ebetso ea motsoako.

Ka kakaretso, thepa e sebetsang ea HPMC/HEC e ba etsa metsoako ea bohlokoa ea thepa ea kaho, ho ntlafatsa ts'ebetso ea bona, le ho ntlafatsa ts'ebetso ea bona. Hangata li sebelisoa lits'ebetsong tse fapaneng, joalo ka seretse sa samente, sekhomaretsi sa lithaele, lisebelisoa tse thehiloeng ho gypsum le lirafshoa.
