HPMC, lebitso le feletseng ke Hydroxypropyl Methylcellulose, ke ether e seng ea ionic cellulose e sebelisoang haholo kahong, meriana, lijo, lik'hemik'hale tsa letsatsi le letsatsi le masimo a mang.
1. Sehlopha ka viscosity
Viscosity ea HPMC ke e 'ngoe ea thepa ea eona ea bohlokoa ea' mele, 'me HPMC e nang le li-viscosity tse fapaneng e na le phapang e kholo ea ts'ebeliso. The viscosity mefuta e fapaneng ho tloha tlaase viscosity (mashome a cps) ho viscosity phahameng (mashome a likete tse cps).
Low viscosity HPMC: Ka tloaelo e sebelisoa lits'ebetsong tse hlokang ho qhibiliha ka potlako kapa ho phalla, joalo ka ho emisoa ha meriana ea metsi, li-sprays, joalo-joalo.
Bohareng ba viscosity HPMC: ho pharaletseng sebelisoa ka letsatsi le letsatsi lik'hemik'hale, tse kang shampoo e, shaoara gel, joalo-joalo, fana ka e leka-lekaneng thickening e le hantle le thepa e ntle rheological.
HPMC e nang le viscosity e phahameng: e sebelisoang haholo linthong tsa kaho, joalo ka seretse se omeletseng, sekhomaretsi sa lithaele tsa ceramic, putty ea kahare le kantle ea lebota, joalo-joalo, e fana ka motenya o motle haholo, ho boloka metsi le thepa ea kaho.
2. Ho hlophisoa ka tekanyo ea ho fetola
Tekanyo ea ho nkela sebaka sa HPMC e bolela palo ea hydroxypropyl le methyl substituent ka molek'hule ea eona, eo hangata e hlahisoang e le MS (hydroxypropyl degree of substitution) le DS (methyl substitution).
Tekanyo e tlase ea sebaka sa HPMC: e qhibiliha kapele mme e sebelisoa haholo lits'ebetsong tse hlokang ho felisoa ka potlako, joalo ka ho roala letlapa la meriana le lino tse tahang hang-hang.
Tekanyo e phahameng ea ho fetola HPMC: E na le viscosity e phahameng le ho boloka metsi hantle, 'me e loketse lihlahisoa tse hlokang viscosity e phahameng le ho boloka metsi a mangata, joalo ka thepa ea kaho le litlolo tse nang le moisturizing tse sebetsang hantle haholo.
3. Ho aroloa ka libaka tsa kopo
Ts'ebeliso e ikhethileng ea HPMC makaleng a fapaneng e fapana haholo, mme e ka aroloa ka mekhahlelo e latelang ho latela likarolo tsa kopo:
thepa ea ho haha
Karolo e ka sehloohong ea HPMC lebaleng la kaho ke ho ntlafatsa ts'ebetso ea kaho le ho tšoarella ha thepa, ho kenyelletsa:
Seretse se omileng: HPMC e fana ka ho boloka metsi hantle, mafura le ts'ebetso, ho ntlafatsa katleho ea kaho le boleng ba sehlahisoa se felileng.
Sekhomaretsi sa lithaele: Eketsa matla a tlamahano le thepa e thibelang ho thella ho netefatsa botsitso le ho tšoarella ha lithaele tse katiloeng.
Pente le putty: Ntlafatsa rheology le ho boloka metsi a pente le putty ho thibela ho phatloha le ho lahleheloa ke phofo.
moriana
Lefapheng la meriana, HPMC e sebelisoa haholo-holo e le li-excipients tsa meriana, ho kenyelletsa:
Letlapa la ho roala: Joaloka lisebelisoa tsa ho roala letlapa, e fana ka bopaki ba mongobo, ho qhibiliha le mesebetsi e tsitsitseng ea ho lokolla ho ntlafatsa botsitso le ponahalo ea lithethefatsi.
Gel: e sebelisetsoa ho lokisa li-gel tsa meriana, ho fana ka ho khomarela hantle le ho lumellana ha lintho.
dijo
HPMC e sebelisoa haholo joalo ka motenya, emulsifier le stabilizer indastering ea lijo, ho kenyelletsa:
Lihlahisoa tsa Noodle: Eketsa ho tiea le elasticity ea hlama, ntlafatsa tatso le sebopeho.
Lihlahisoa tsa lebese: E le emulsifier le stabilizer, e thibela stratification le pula ea lihlahisoa tsa lebese le ho ntlafatsa botsitso ba sehlahisoa.
Lik'hemik'hale tsa letsatsi le letsatsi
Ka lik'hemik'hale tsa letsatsi le letsatsi, HPMC e sebelisoa haholo e le li-thickeners le stabilizers, ho kenyelletsa:
Shampoo le gel ea shaoara: Fana ka viscosity e itekanetseng le rheology ho ntlafatsa boiphihlelo ba tšebeliso ea sehlahisoa.
Lihlahisoa tsa tlhokomelo ea Letlalo: E le motenya le moisturizer, e ntlafatsa phello ea moisturizing le phihlelo ea tšebeliso ea sehlahisoa.
4. Merero e meng e khethehileng
HPMC e ka boela ea sebelisoa masimong a mang a ikhethileng, joalo ka meepo ea masimong a oli, indasteri ea ceramic, indasteri ea pampiri, jj.
Tlhahiso ea Oilfield: e sebelisetsoang ho cheka maro le maro a fracturing ho fana ka thepa e babatsehang ea ho teteka le ho fokotsa tahlehelo ea mokelikeli.
Indasteri ea Ceramic: e sebelisoang e le setlamo le se emisang ho ntlafatsa botsitso le mokelikeli oa seretse sa ceramic.
Indasteri ea ho etsa pampiri: e sebelisetsoang ho phekola holim'a pampiri ho eketsa matla a eona le ho hanyetsa metsi.
Joalo ka motsoako oa cellulose o sebetsang ka bongata, HPMC e na le thepa e ntle haholo ea 'mele le ea lik'hemik'hale le menyetla e pharaletseng ea ts'ebeliso. Mefuta e fapaneng ea HPMC e na le litšobotsi tsa bona mabapi le viscosity, tekanyo ea ho fetola le tšebeliso. Ho khetha mofuta o nepahetseng oa HPMC ho latela litlhoko tse ikhethileng tsa kopo ho ka ntlafatsa haholo ts'ebetso le boleng ba sehlahisoa. Ka tsoelopele ea mahlale le thekenoloji le katoloso ea mafapha a ts'ebeliso, ts'ebeliso ea HPMC e tla ba kholo le ho teba.
