Tšebeliso ea Hydroxypropyl Methyl Cellulose ho Iketsetse boemo

Hydroxypropyl methylcellulose HPMC hangata e sebelisoa liindastering tse ngata. Leha batho ba bangata ba sa e utloisise hantle, e ama liindasteri tse fapaneng. Ts'ebetsong ea kaho ea indasteri ea kaho, hangata e sebelisoa haholo bakeng sa masela a marako le ho lila. , Caulking le masimo a mang a kaho ea mechine, haholo-holo kahong ea mekhabiso. Hangata e sebelisetsoa ho kenya lithaele, limmabole le mekhabiso e meng ea polasetiki. E na le tekanyo e phahameng ea ho khomarela 'me e ka boela ea fokotsa bongata ba samente e sebelisoang. E sebelisoa indastering ea ho roala. , Haholo-holo e sebelisoang e le motenya, e ka etsa hore lera le be le letle le le khanyang, le se ke la e-ba bonolo ho tlosa phofo, le ntlafatsa ts'ebetso ea ho lekanya, joalo-joalo, haholo-holo bakeng sa kopo tšimong ea ho haha ​​​​seretse sa ho ikemela.

Seretse se ikemetseng se boreleli, 'me bokhoni ba ho ikamahanya le lihlahisoa tse khethehileng tsa seretse se omeletseng, ho ikamahanya ha sona, kaha bokhoni ba ho fihlela lera le se nang moroalo le boreleli bo bohlokoa haholo, bakeng sa lihlahisoa tse ntle tsa ho ikemela, li tla ba le. tshebetso e loketseng ea ho sebetsa, 'me ba khona ho ka nako ea kaho, boloka tshebetso ya eona ka kakaretso ea, le bokhoni ba ho iphekola, kahoo, Sena se hloka seretse nakong ena ka botlalo netefatsa botsitso le ho lumellana, 'me ea bobeli, bakeng sa seretse empa hape o na le matla a itseng, ho akarelletsa le matla a ho jara le matla a tlamang a holim'a setsi, tsena ke maemo a motheo bakeng sa lisebelisoa tsa fatše li ka sebelisoa ka mokhoa o tloaelehileng, ho ipeha boemong ba ts'ebetsong ena, ts'ebetso ea hydroxypropyl methyl cellulose ether e amoheleha ho ikopanya le rona, e ka nka khato. e le thickening e matlafalitsoeng ho khomarela, E boetse e na le litšobotsi tsa ho boloka metsi a mangata le nako e telele ea ho haha.

Ha viscosity ea hydroxypropyl methyl cellulose e phahame, ho molemo hore viscosity ea thepa e entsoeng ka samente e fetoloe, empa haeba viscosity e le khōlō haholo, e tla ama ho phalla le ho sebetsa ha thepa. Ho feta moo, phello e matla ea hydroxypropyl methyl cellulose e ka boela ea eketsa tlhokahalo ea metsi ea thepa e thehiloeng ho samente, kahoo ea eketsa tlhahiso ea seretse. Seretse se ikemetseng le konkreite e iketsetsang, e hlokang metsi a mangata, e hloka viscosity e tlase ea hydroxypropyl methyl cellulose. Low viscosity cellulose ether e ka bapala phello e ntle ea ho emisoa, e ka thibela ho lula ha slurry, e boetse e na le mosebetsi oa exudation, hape e ka etsa bonnete ba hore e ke ke ea ama phello ea phallo ea seretse se ikemetseng, kaho e bonolo, empa hape e na le litšobotsi tsa Gao Baoshui, e ka etsa hore bokaholimo ba phallo ka mor'a hore phello e be betere haholo, e fokotse ho fokotseha ha seretse, e qobe ho phunya crack, joalo-joalo.

Hydroxypropyl methyl cellulose e sebelisoa haholo mefuteng eohle ea thepa ea moaho. Ha e sebelisoa ka seretse se ikemetseng, se na le litšobotsi tse latelang:

1, ts'ebetso e phahameng ea ho boloka metsi, e ka lelefatsa nako ea ts'ebetso ea seretse se ikemetseng, ea ntlafatsa ho tšoarella ha seretse, ea eketsa matla a eona a tlamahano, ts'ebetso e ntle haholo ea ho kopanya metsi, e ka fokotsa molora oa fatše.

2, ho lumellana ho matla, ho loketse mefuta eohle ea thepa ea mohaho, seretse sa ho itšehla thajana, ho fokotsa nako ea ho teba, ho fokotsa sekhahla sa ho omisa, ho qoba lerako le fatše ho phunyeha moropa le mathata a mang.

3, thibela ho tsoa mali, e ka bapala karolo e betere ea ho emisoa, ho thibela ho beoa ha slurry le ts'ebetso e ntle ea ho tsoa mali.

4, boloka thepa e ntle ea phallo, viscosity e tlase ea hydroxypropyl methyl cellulose e ke ke ea ama phallo ea slurry, kaho e bonolo, ts'ebetso e ntle ea ho boloka metsi, e ka hlahisa bokaholimo bo botle kamora ho ikemela, ho qoba ho phatloha ha moropa, cellulose ether le ts'ebetso e tsitsitseng ea bond. , ho netefatsa ka botlalo boleng bo botle, hammoho le bokhoni ba ho ikemela, Ho laola sekhahla sa ho boloka metsi ho ka etsa hore e tiee kapele le ho fokotsa ho honyela le ho petsoha.
