1.Introduduction:
Ho iphahamisa litakatso tsa boithati ho fetolela indasteri ea kaho ka ho fana ka tharollo e sebetsang le e sebetsang ea ho bokella libaka tse sa lekanang. Motsoako o le mong oa bohlokoa o kenyang chelete ea bohlokoa ho ts'ebetso ea bona ke hydroxyproppyl methylcelllulose (HPMC). Sehloohong sena, re tla hlahloba ka thepa le mesebetsi ea HPMC mabapi le ho iphahamisa, ho totobatsa lintho tsa bohlokoa ho fihlela mekhoa ea fatše.
2. TLHOKOMELISO HO HPMC:
Hydroxypropypropiyproppy, e tsejoang e le HPMC, ke mpa ea celmc, e tsoa ho selefoui, haholo-holo cellulose. E sebelisoa haholo ka thepa ea eona ea kaho ka lebaka la thepa ea eona e ikhethang, ho kenyelletsa le ho boloka metsi, ho holisa metsi le ntlafatso ea ho ikamahanya le ho ikamahanya le ntlafatso. HPMC e fumaneha literede tse fapaneng, ka lipehelo tse ikhethileng tsa litšoantšo le maemo a sebaka, a lumella lits'ebetso tse fapaneng ka liforomo tse fapaneng.
3.Re ea HPMC ka ho ikhethela:
Ho Boloka Metsi: HPMC e sebetsa e le moemeli oa metsi a bolokang metsi, a lelefatsa lintho tse hlakileng tsa lisebelisoa tsa mafeto. Hygrata ea nako e telele ha e netefatse feela ka lebaka le nepahetseng nakong ea kopo empa e boetse e khothalletsa ntlafatso e ntle ebe e fokotsa ho thefula.
Ho ntlafalitsoe: Ka ho ntlafatsa thepa ea ho ts'oaroa le ho phalla ea mortar, HPMC e nolofalletsa ho fana ka kopo mme o etsa tlhahiso e tšoanang. Sena se fella ka sena se matlafatsang le ho felisa tlhokahalo ea ho ba le maemo a mangata a ho boloka ka bongata, ho boloka litšenyehelo le litšenyehelo tsa basebetsi.
Ho senya: Maeto a khokhothelang le a khomaretsoeng a HPMC a kenya letsoho ho koroneng ea likaroloana tsa sistimi, ho fokotsa sebopeho sa microcracks seretse se foutsoeng. Sena se ntlafatsa botšepehi ba sistimi ea fatse mme o ntlafatsa ho hanela ho bakoang ke ho omisa shrinkage kapa khatello ea kutlo.
Ho tsamaisana le litlatsetso: HPMC e bonts'a mokhoa o fetisisang ka mefuta e mengata ea litlatsetso tse sebelisoang ka mokhoa o tloaelehileng ea ho iphahamisa, joalo ka bafetehi, le ho beha li-acsole tsa moea. Phapang ena e lumella hore ho be le mokhoa oa ho kopanya ho kopanngoa ka litlhoko tse ikhethang tsa ts'ebetso le maemo a tikoloho.
Matla a ntlafalitsoeng a band: HPMC e theha filimi e tsoelang pele, e khothalletsang ho latela moea o matla pakeng tsa seretse le seretse se ka tlaase. Sena se ntlafatsa matla a bont, o fokotsa kotsi ea ho lieha kapa ho rera, 'me u etsa hore motho a tšoarelle nako e telele ea tsamaiso ea fatše.
4. Litataiso:
Ha u kenyelletsa HPMC ho ea ho ho ikhethela, ho bohlokoa ho latela tataiso ea litekanyetso tse fanoeng ke Baetsi. Ts'ebeliso e mpe ea HPMC e ka fella ka pono e feteletseng, linako tse mpe tsa ho beha nako e telele, kapa li senya thepa ea tšebetso. Tekanyetso e sa sebetseng hantle, e sa sebetseng hantle ea HPMC e ka lebisa ho ho ikoetlisa hampe, ho thibela metsi, kapa bofokoli ba metsi.
Hydroxypropypropity Methylceluselose e bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso le ho tšoarella ha ho iphumanela lintho tse bonoang. Malinyane a eona a mafili a kentse monyetla oa ho ntlafatsa menyetla, le matla a tlamahane, 'me ea tlamand'men e le hore e be le lisebelisoa tse bohlokoa ka lebaka la kaho ea bolumeli. Ka ho utloisisa karolo ea HPMC le ho latela litataiso tse nepahetseng tsa ts'ebeliso, botala bo bonolo, bo boreleli, bo boreleli, bo boreleli, bo boreleli, bo boreleli, bo boreleli bo lekanang bo khotsofatsang litlhokahalo tsa merero ea kajeno.
