Ka lebaka la ho theha putlama, litlatsetso tsa Ether li-Adding tsa Ether li bapala karolo ea bohlokoa.HydroxypropypropyLese (HPMC), e le e 'ngoe ea ena e leng' nete e sebelisoang hangata e sebelisoang ka thata, e ka ntlafatsa liketsahalo, ts'ebetso ea kaho le ho tsitsipana hoa polokelo.
1. Thepa ea mantlha ea hydroxypropyl methylcell
HPMC ke polymer ea se nang moea e qholotsang metsi ka ho boloka metsi ho boloka metsi ho boloka metsi, ho hasana, ho qhekella le ho etsa lintho. Kelellong ea eona e anngoe ke boemo ba nke ke karolo, tekanyo ea polymeriation le maemo a lillo. Tharollo ea Aquanous ea Lits'oaetso BBOHPMC e bonts'a mefuta ea mokelikeli oa pseudoplassiet, e leng pono ea tharollo e fokotseha, viscoity ea ho atoloha.
2. Phello ea HPMC ho Carty Viscosity
2.1 Liphello tsa Thickening
HPMC e theha tharollo e phahameng ea liketsahalo kamora ho qhala ka metsing. Tšusumetso ea eona ea thipa e bonahala haholo linthong tse latelang:
Ho ntlafatsa thipixottacty ea Ptloa: HPMC e ka boloka molato Vising e phahameng ha e le Stastering ea ho sesa le ho ntlafatsa ts'ebetso ea kaho.
Ho ntlafatsa ts'ebetso ea litopo: palo e lekanang ea HPMC e ka ntlafatsa leseli la bohloeki, ho etsa hore ho be le litšila le ho fokotsa ho hanyetsa.
Ho ama matla a hoqetela: matla a tona ea HPMC a etsa hore ho ka hahuoa le ho ntlafatsa ts'ebetso e thata kamora ho haha.
2.2 Phello mabapi le ts'ebetso ea hydration
HPMC e na le thepa e ntle ea metsi e nang le metsi a ho boloka metsi a matla, ka ho etsa joalo e ka fihla pheletsong ea tlhaho le ho senya mokhoa oa ho hana. Leha ho le joalo, liketsahalo tse phahameng haholo tsa HPMC li tla ama lebelo le letle le ho omisa polasetiki, e hlahisoang ka mokhoa o fokotsehileng oa kaho. Ka hona, palo ea HPMC e hloka ho netefatsa hore ho na le melemo ea mathata nakong ea ho thatafatsa.
Metsoalle ea 2.3 pakeng tsa boima ba limompecular tsa hpmc le viccosity ea thepa
Ha boima ba limolek'hule tsa HPMC, pono e kholo ea tharollo ea eona e telele. Ka popelong, tšebeliso ea hpmcc (joalo ka mofuta o moholo ho feta 100,000 MTA `e ea ho boloka metsi le e thibelang mafu . Ka hona, tlasa litlhoko tse fapaneng tsa kaho, HPMC ka pono e loketseng e lokela ho khethoa ho thibela metsi, ho ikoetlisa le ts'ebetso ea ho qetela le ts'ebetso ea ho qetela.
2.4 Phello ea litekanyetso tsa HPMC mabapi le liketsahalo tse bulehileng
Palo ea li tšoenyehile®HPMC e ekelitsoeng e na le phello e ntle ho tsebiso ea popa, 'me litekanyetso hangata li pakeng tsa 0,1% le 0.5 le 0.5%. Ha litekanyetso tsa HPM li le tlase, matla a tona ea putter a haella, 'me a ka se khone ho ntlafatsa katleho le ho boloka metsi hantle ka katleho le metsi. Ha karolo e phahame haholo, ke pono ea litopo e kholo haholo, ho hanyetsa ho eketseha hoa eketseha, 'me e ka ama lebelo le omileng la molato. Ka hona, hoa hlokahala ho khetha palo e nepahetseng ea HPMC ho latela mokhoa oa litopo le tikoloho ea kaho.
HydroxypropypropinyL methylceulose e bapala karolo ea ho toba, ea metsi le ho ntlafatsa mosebetsi ka mokhoa o nepahetseng. Boima ba limolek'hule, degree ea ho nkeloa sebaka sa bolulo le palo eaHpmce tla ama pono ea popo. Palo e loketseng ea HPMC e ka ntlafatsa ts'ebetso le ho hanyetsa metsi a ho hanyetsa thepa le ho hanyetsa ka metsing, ha a tla eketsa bothata ba ho aha. Ka hona, ts'ebelisong ea 'nete ea popa, litšobotsi tsa litlhokahalo tsa li-viscosity le litlhoko tsa kaho tsa HPMC li lokela ho nahanoa ka mokhoa oa kaho le boleng ba ho qetela.
