Mabapi le hydroxypropyl methylcellulose nakong ea tšebeliso ea putty powder

1. Mathata a tloaelehileng ka putty powder

[Ho omisa ka potlako] Sena se amana haholo-holo le palo ea phofo ea molora ea calcium e kenyelitsoeng (e kholo haholo, e ka fokotsa ka nepo palo ea phofo ea molora e sebelisoang ka mokhoa oa putty) le tekanyo ea ho boloka metsi ea hydroxypropyl methylcellulose (HPMC), 'me e. e boetse e amana le E amana le ho omella ha lebota.

[Letlalo le ho kobeha] Sena se amana le sekhahla sa ho boloka metsi.Hydroxypropyl methylcellulose (HPMC) e na le viscosity e tlaase 'me e tloaelehile ho boemo bona kapa palo ea ho eketsoa e nyenyane.

[Ho tlosoa ha phofo ka hare ho lebota la putty powder] Sena se amana le palo ea phofo ea molora ea calcium e kentsoeng (palo ea phofo ea molora ka har'a motsoako oa putty e nyenyane haholo kapa bohloeki ba phofo ea molora oa calcium bo tlaase haholo, 'me palo ea molora. khalsiamo phofo ka phofo ea putty phofo e lokela ho eketsoa ka mokhoa o nepahetseng) Ka nako e ts'oanang, e boetse e amana le palo le boleng ba hydroxypropyl methylcellulose (HPMC), e bonahalang ka tekanyo ea ho boloka metsi ea sehlahisoa.Sekhahla sa ho boloka metsi se tlaase, 'me calcium oxide ka har'a phofo ea molora ea khalsiamo ha e amohelehe ka ho feletseng Calcium hydroxide conversion hydration) nako ha e lekane, e bakoa.

[Blisting] Sena se amana le mongobo o omileng le ho bata ha lebota, hape se amana le kaho.

[Ho hlaha lintlha tsa phini] Sena se amana le selulose, e nang le thepa e fokolang ea ho etsa lifilimi, hape le litšila tse ho hydroxypropyl methylcellulose (HPMC) li arabela hanyane ka molora oa calcium.Haeba karabelo e le matla, phofo ea putty e tla bonahala e le tofu Slag state.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.

[Mahaha a seretse se chesang le li-pinholes li hlaha] 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.

[Putty e bonolo ho petsoha le ho fetoha mosehla ka mor'a ho omisa] Sena se amana le ho eketsoa ha phofo e ngata ea molora oa calcium.Haeba palo ea phofo ea molora ea calcium e eketsoa haholo, ho thatafala ha putty phofo ho tla eketseha ka mor'a ho omisa.Ke ho thatafala feela ntle le ho feto-fetoha ha maemo ho tla qhekella habonolo, haholo-holo Ho na le monyetla oa ho peperana ha o 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.
