Sena se amana haholo le palo ea phofo ea molora ea calcium e kenyelitsoeng (e kholo haholo, palo ea phofo ea molora ea calcium e sebelisoang ka mokhoa oa putty e ka fokotsoa ka mokhoa o nepahetseng) le tekanyo ea ho boloka metsi ea hydroxypropyl methylcellulose (HPMC), hape e amana le ho omella hoa lebota ho amanang.
Ho ebola le ho thetheha
Sena se amana le tekanyo ea ho boloka metsi, e leng bonolo ho etsahala ha viscosity ea hydroxypropyl methylcellulose (HPMC) e le tlaase kapa chelete e kenyelletsoeng e nyenyane.
De-powdering ea ka hare lerako putty phofo
Sena se amana le palo ea phofo ea molora oa calcium (tekanyo ea phofo ea molora ka har'a foromo ea putty e nyane haholo kapa bohloeki ba phofo ea molora ea khalsiamo e tlase haholo, 'me palo ea phofo ea molora ka har'a foromo ea putty powder e lokela ho ba joalo. e eketsehile ka tsela e nepahetseng), hape e amana le palo ea hydroxypropyl methyl Palo ea baselulose (HPMC) e amana le boleng, bo bonts'ang sekhahla sa ho boloka metsi sa sehlahisoa. Sekhahla sa ho boloka metsi se tlaase, 'me nako ea phofo ea molora ea calcium (calcium oxide ka molora oa calcium powder ha e fetohe ka ho feletseng ho calcium hydroxide) ha ea lekana. ,e bakileng.

Sena se amana le mongobo o omileng le ho bata ha lebota, hape se amana le kaho.
ntlha ea pin
Sena se amana le cellulose, e nang le thepa e mpe ea ho etsa lifilimi. Ka nako e ts'oanang, litšila tse ka har'a hydroxypropyl methylcellulose (HPMC) li arabela hanyane ka molora oa calcium. Haeba karabelo e le matla, phofo ea putty e tla ba boemong ba masala a linaoa. E ke ke ea behoa leboteng, 'me ha e na matla a momahaneng ka nako e le' ngoe. Ntle le moo, lihlahisoa tse kang hydroxypropyl methylcellulose (HPMC) e kopantsoeng le sehlopha sa carboxymethyl le tsona li hlaha boemong bona.
Ho hlaha seretse se chesang le likoti
Ho hlakile hore sena se amana le tsitsipano ea metsi holim'a metsi a hydroxypropyl methylcellulose (HPMC) tharollo ea metsi. Khatello ea metsi ea hydroxyethyl aqueous solution ha e bonahale. Ho ka ba molemo ho etsa phekolo ea ho qetela.
Ka mor'a hore putty e ome, ho bonolo ho petsoha le ho fetoha mosehla
Sena se amana le ho eketsoa ha phofo e ngata ea molora-calcium. Haeba palo ea phofo ea molora-calcium e eketsoa haholo, ho thatafala ha putty phofo ho tla eketseha ka mor'a ho omisa. Haeba phofo ea putty e se na phetoho, e tla phunyeha habonolo, haholo-holo ha e tlas'a matla a ka ntle. E boetse e amana le boemo bo phahameng ba calcium oxide ka phofo ea molora oa calcium.
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 senngoa 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.
