Ho Hlahlobisisa Bohlokoa ba Hydroxypropyl Methyl Cellulose Ether (HPMC) ho Dry Mixed Mortar

Hydroxypropyl Methyl Cellulose Ether (HPMC)e eme e le karolo ea bohlokoa ho thehoeng ha seretse se omeletseng se tsoakiloeng, se bapala karolo e ngata ho ntlafatsa ts'ebetso le thepa ea sona.

Sebopeho sa Lik'hemik'hale le Lintho tsa HPMC:

HPMC ke non-ionic cellulose ether nkiloeng tlhaho polymer selulose ka letoto la liphetoho lik'hemik'hale. Sebopeho sa eona sa lik'hemik'hale se na le likarolo tse pheta-phetoang tsa limolek'hule tsa tsoekere tse nang le hydroxypropyl le methyl substituent tse hokelletsoeng ho lihlopha tsa hydroxyl. Tokisetso ena ea meralo e fana ka lisebelisoa tse 'maloa tse molemo ho HPMC, ho kenyelletsa ho boloka metsi, bokhoni bo matla, ntlafatso ea ho khomarela, le phetoho ea rheology.

Poloko ea Metsi le Mosebetsi:

E 'ngoe ea mesebetsi ea mantlha ea HPMC ka seretse se omeletseng se tsoakiloeng ke bokhoni ba eona ba ho boloka metsi ka har'a matrix a seretse. Thepa ena e bohlokoa bakeng sa ho boloka ts'ebetso le ho lelefatsa ts'ebetso ea hydration ea lisebelisoa tsa samente. Ka ho etsa filimi e tšesaane ho pota-potile likaroloana tsa samente, HPMC e thibela ka katleho tahlehelo ea metsi e potlakileng ka ho fetoha mouoane, kahoo e eketsa nako e teng bakeng sa ho kopanya, ho kenya kopo le ho qeta.

Ntlafatso ea Kamano le Momahano:

HPMC e sebetsa e le tlamahano ea bohlokoa mefuteng e omeletseng ea seretse se omeletseng, e ntlafatsang boleng ba ho khomarela le ho momahano. Sebopeho sa eona sa limolek'hule se thusa ho sebelisana ka matla le li-substrates tse fapa-fapaneng, ho khothalletsa ho khomarela hantle libakeng tse kang litene, konkreite le lithaele. Ho feta moo, HPMC e kenya letsoho ho momahaneng ha seretse ka ho ntlafatsa matla a maqhama pakeng tsa likaroloana, e leng se hlahisang sehlahisoa sa ho qetela se tšoarellang le se matla haholoanyane.

Thickening le Sag Resistance:

Ho kenyeletsoa ha HPMC mefuteng e omeletseng ea seretse se omeletseng ho fana ka thepa e teteaneng, ka tsela eo ho thibela ho theoha kapa ho thella nakong ea ts'ebeliso e otlolohileng. Bokhoni ba ho fetola li-viscosity ba HPMC bo nolofalletsa seretse ho boloka sebopeho sa sona le ho tsitsisa, ho netefatsa ho tšoana le botsitso nakong eohle ea kopo. Sena se bohlokoa haholo lits'ebetsong tse otlolohileng kapa tse otlolohileng moo ho hanyetsanang le sag ho leng bohlokoa ho thibela tšenyo ea thepa le ho netefatsa boits'oaro ba sebopeho.

Matla a Ntlafetseng le Matla a ho sebetsa:

Ho ba teng ha HPMC mefuteng e ommeng e tsoakiloeng ea seretse ho matlafatsa haholo ts'ebetso le ho pompa, ho nolofatsa ts'ebeliso le ho fokotsa litlhoko tsa basebetsi. Ka ho fana ka lubricity le ho fokotsa likhohlano pakeng tsa likaroloana tsa seretse, HPMC e ntlafatsa litšobotsi tsa phallo ea motsoako, e leng ho lumellang ho pompa le ho sebelisoa hamonate ntle le ho arohana kapa ho thibela. Sena se fella ka tlhahiso e eketsehileng le katleho libakeng tsa kaho, e leng se lebisang ho bolokoeng ha litšenyehelo le linako tse ntlafalitsoeng tsa merero.

Tlhophiso e Laolehileng le Pheko:

HPMC e bapala karolo ea bohlokoa ho laola maemo le ho folisa libopeho tsa seretse se omeletseng se kopaneng. Ka ho chechisa tšebetso ea hydration ea thepa ea samente, HPMC e eketsa nako ea ho sebetsa ea seretse, e fana ka nako e lekaneng ea ho beoa, ho lekanya le ho phethela. Sebaka sena se laoloang se boetse se fokotsa kotsi ea ho satalla pele ho nako kapa ho petsoha, haholo-holo maemong a leholimo a chesang kapa a omileng, ho netefatsa ts'ebetso e nepahetseng le ho tšoarella ha sebopeho sa ho qetela.

Ho lumellana le li-Additives:

Molemo o mong oa bohlokoa oaHPMCka seretse se omeletseng se tsoakiloeng ke ho lumellana ha eona le li-additives tse fapaneng le metsoako e sebelisoang ho ntlafatsa thepa e itseng. Ebang e kopantsoe le li-air-entraining agents, accelerators, kapa plasticizers, HPMC e bonts'a ts'ebelisano e ntle haholo le liphello tsa synergistic, e ntlafatsang ts'ebetso le ts'ebetso ea seretse. Mokhoa ona oa ho feto-fetoha o lumella libopeho tse lokiselitsoeng ho finyella litlhoko tse khethehileng tsa morero, ho tloha ho maemo a potlakileng ho ea ho lisebelisoa tse matla haholo.

bohlokoa ba Hydroxypropyl Methyl Cellulose Ether (HPMC) ka seretse se omeletseng se tsoakiloeng se ke ke sa feteletsoa. Mehaho ea eona e nang le mesebetsi e mengata, e kenyelletsang ho boloka metsi, ho ntlafatsa ho khomarela, matla a ho tiea, le phetoho ea rheology, e kenya letsoho haholo ts'ebetsong, ho sebetsa le ho tšoarella ha metsoako ea seretse. E le motsoako oa bohlokoa, HPMC e etsa hore ho be le lirekere tsa boleng bo holimo, tse tenyetsehang tse loketseng mefuta e mengata ea likopo tsa kaho, 'me qetellong li tsamaise katleho, botsitso le boqapi indastering ea kaho.
