Tšebeliso ea mantlha ea hydroxypropyl methylcellulose ke efe?
—— Karabo: HPMC e sebelisoa haholo linthong tsa kaho, lijalo, lirese tsa maiketsetso, lirafshoa, meriana, lijo, masela, temo, litlolo, koae le liindasteri tse ling. HPMC e ka aroloa ka sehlopha sa kaho, sehlopha sa lijo le sehlopha sa meriana ho latela sepheo. Hajoale, boholo ba lihlahisoa tsa lapeng ke tsa boemo ba kaho. Sebakeng sa kaho, phofo ea putty e sebelisoa ka bongata, hoo e ka bang 90% e sebelisetsoa putty powder, 'me e setseng e sebelisetsoa seretse sa samente le sekhomaretsi.
Mokhoa oa ho khetholla boleng ba HPMC habonolo le ka mokhoa o hlakileng?
—— Karabo: (1) Bosoeu: Le hoja bosoeu bo ke ke ba tseba hore na HPMC e bonolo ho e sebelisa, ’me haeba mahlahana a bosoeu a eketsoa nakong ea tlhahiso, e tla ama boleng ba eona. Leha ho le joalo, boholo ba lihlahisoa tse ntle li na le bosoeu bo botle. (2) Bokhabane: Bokhabane ba HPMC hangata bo na le 80 mesh le 100 mesh, le 120 mesh e tlase. Boholo ba HPMC e hlahisoang Hebei ke 80 mesh. Ha botle bo botle, ka kakaretso, bo betere. (3) Ho fetisa leseli: kenya hydroxypropyl methylcellulose (HPMC) ka metsing ho etsa colloid e bonaletsang, 'me u shebe phetiso ea eona e bobebe. Ha khanya e fetisa ka bongata, e molemo, e bontšang hore ho na le li-insoluble tse fokolang ho eona. . The permeability ea li-reactor tse otlolohileng hangata li ntle, 'me tsa li-reactor tse tšekaletseng li mpefala, empa ha ho bolele hore boleng ba li-reactor tse otlolohileng bo betere ho feta ba li-reactor tse tšekaletseng,' me boleng ba sehlahisoa bo khethoa ke lintlha tse ngata. (4) Matla a khoheli a khethehileng: Ha matla a khoheli a itseng a le maholo, boima bo ba betere. Ntho e ikhethang e kholo, ka kakaretso hobane litaba tsa sehlopha sa hydroxypropyl ho eona li phahame, 'me litaba tsa sehlopha sa hydroxypropyl li phahame, ho boloka metsi ho molemo. (5) Ho chesa: Nka karolo e nyenyane ea sampole ’me u e hotetse ka mollo, ’me masalla a masoeu ke molora. Ntho e tšoeu haholoanyane, boleng bo bobe le ho feta, 'me ho batla ho se na masala a thepa e hloekileng.
Theko ea hydroxypropyl methylcellulose ke eng?
—–Karabo; theko ea hydroxypropylmethyl e itšetlehile ka bohloeki ba eona le litaba tsa molora. Ha ho hloeka ho phahame, ho fokotseha ha molora, theko e phahameng. Ho seng joalo, ho theola bohloeki, ho ba le molora o eketsehileng, theko e tlaase. Ho fihla ho li-yuan tse 17,000 ka tone. 17,000 yuan ke sehlahisoa se hloekileng se batlang se se na litšila. Haeba theko ea yuniti e phahame ho feta 17,000 yuan, phaello ea moetsi e eketsehile. Ho bonolo ho bona hore na boleng bo botle kapa bo bobe ho latela palo ea molora ka hydroxypropyl methylcellulose.
Ke viscosity efe ea hydroxypropyl methylcellulose e loketseng putty phofo le seretse?
—–Karabo; putty powder ka kakaretso ke li-yuan tse 100,000, 'me tlhoko ea seretse e phahame,' me e hloka li-yuan tse 150,000 hore e be bonolo ho e sebelisa. Ho feta moo, mosebetsi oa bohlokoa ka ho fetisisa oa hydroxypropyl methylcellulose ke ho boloka metsi, ho lateloa ke ho teteaneng. Ka phofo ea putty, hafeela ho boloka metsi ho le molemo 'me viscosity e tlaase (70,000-80,000), hape e ka khoneha. Ha e le hantle, viscosity e ka tlase ho 100,000 e phahame, 'me ho boloka metsi ho lekanyelitsoeng ho molemo. Ha viscosity e feta 100,000, viscosity e na le phello ea ho boloka metsi Tšusumetso ha e kholo.
