2. Ke hobane'ng ha putty powder e fetoha e mosesaane ka mor'a ho eketsa metsi?
Hydroxypropyl methylcellulose (HPMC) e sebelisoa e le ntho e teteaneng le e bolokang metsi ka har'a mafura.Ka lebaka la thixotropy ea hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose ka putty powder Ho eketsoa ha HPMC ho ile ha boela ha baka thixotropy ka mor'a ho eketsa metsi ho putty.thixotropy ena e bakoa ke ho senyeha ha mohaho o hlephileng o kopantsoeng oa likarolo tsa putty powder.Sebopeho sena se hlaha nakong ea phomolo 'me se senyeha tlas'a khatello ea kelello.Ka mantsoe a mang, viscosity e fokotseha tlas'a ho sisinyeha, 'me viscosity e hlaphoheloa ha e eme.
3. Ke hobane'ng ha putty e batla e le boima ka mokhoa oa ho senya?
Tabeng ena, viscosity ea hydroxypropyl methylcellulose (HPMC) e sebelisoang hangata e phahame haholo, 'me bahlahisi ba bang ba sebelisa li-yuan tse 200,000 ho etsa putty.Putty e hlahisoang ka tsela ena e na le viscosity e phahameng, kahoo e tla teba ha batch scraping.maikutlo a.Palo e khothalletsoang ea putty bakeng sa marako a ka hare ke 3-5 kg, 'me viscosity ke 80,000-100,000.
4. Ke hobane'ng ha u nahana hore viscosity ea hydroxypropyl methylcellulose (HPMC) e nang le viscosity e tšoanang e fapane mariha le lehlabula?
Ka lebaka la gelation ea mocheso oa sehlahisoa, viscosity ea putty le seretse e tla fokotseha butle-butle ka ho eketseha ha mocheso.Ha mocheso o feta mocheso oa gel oa sehlahisoa, sehlahisoa se tla kenngoa metsing ebe se lahleheloa ke viscosity ea sona.Mocheso oa kamore lehlabula hangata o ka holimo ho likhato tse 30, tse fapaneng haholo le mocheso oa mariha, kahoo viscosity e tlaase.Ho khothalletsoa ho khetha sehlahisoa se nang le viscosity e phahameng ha u sebelisa sehlahisoa lehlabula, kapa ho eketsa palo ea hydroxypropyl methylcellulose (HPMC), le ho khetha sehlahisoa se nang le mocheso o phahameng oa gel.
