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 arola ka tekanyo ea ho kenya sebaka
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:
Ho roala Letlapa: 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 libaka tsa ts'ebeliso, ts'ebeliso ea HPMC e tla ba kholo le ho teba.
