Ts'ebetsong ea tlhahiso ea phofo ea putty, ho eketsa chelete e loketseng of Hydroxypropyl Methyl Cellulose (HPMC)e ka ntlafatsa ts'ebetso ea eona, joalo ka ho ntlafatsa rheology ea putty powder, ho eketsa nako ea kaho, le ho eketsa ho khomarela. HPMC ke setenya se tloaelehileng le se feto-fetohang, se sebelisoang haholo ho thepa ea kaho, liphahlo, likhomaretsi le masimo a mang. Bakeng sa phofo ea putty, ho eketsa HPMC ho ke ke ha ntlafatsa feela ts'ebetso ea kaho, empa hape ho ntlafatsa bokhoni ba ho tlatsa le ho thibela ho phunyeha ha putty.

 

Karolo ea hydroxypropyl methylcellulose
Ho ntlafatsa ts'ebetso ea mokelikeli le kaho: HPMC e na le phello e ntle ea ho tiisa, e ka ntlafatsang metsi a phofo ea putty, ho etsa hore phofo ea putty e be e ts'oanang le ho se khone ho phalla ha e sebelisoa le ho lokisoa, le ho ntlafatsa katleho le boleng ba mohaho.

 

Ho matlafatsa ho khomarela: Ho eketsoa ha HPMC ho ka ntlafatsa ho khomarela pakeng tsa putty powder le thepa ea motheo, ho qoba mathata a kang putty powder e oelang le ho senya.

 

Ho ntlafatsa ho boloka metsi: HPMC e ka eketsa ho boloka metsi a putty powder, ho fokotsa lebelo la mouoane oa metsi, kahoo ho thibela putty ho omella le ho senya, le ho thusa putty ho boloka ho tšoana nakong ea ho omisa.

 

E matlafalitsoe ho hanyetsa ho phatloha: Sebopeho sa polymer sa HPMC se ka ntlafatsa ho feto-fetoha ha phofo ea putty le ho fokotsa mapetsong a bakoang ke ho phunyeha, ho fetoha ha mocheso kapa ho senyeha ha motheo.

 

Palo ea Hydroxypropyl Methylcellulose E Ekelitsoe
Ka kakaretso, palo ea hydroxypropyl methylcellulose e kenyelletsoeng hangata e pakeng tsa 0.3% le 1.5% ea boima bohle ba phofo ea putty, ho itšetlehile ka mofuta oa putty powder o sebelisitsoeng, ts'ebetso e hlokahalang, le litlhoko tsa kopo.

 

Phofo e tlaase ea viscosity putty: Bakeng sa li-putty tse ling tse hlokang metsi a mangata, ho ka sebelisoa chelete e tlaase ea HPMC, hangata e ka bang 0.3% -0.5%. Sepheo sa mofuta ona oa putty powder ke ho ntlafatsa ts'ebetso ea kaho le ho eketsa nako e bulehileng. HPMC e feteletseng e ka 'na ea etsa hore phofo ea putty e be viscous haholo' me e ame kaho.

 

Phofo e phahameng ea viscosity putty: Haeba sepheo ke ho ntlafatsa ho khomarela le ho hanyetsa ho phatloha ha putty, kapa bakeng sa marako a nang le phekolo e thata ea motheo (e kang libaka tse nang le mongobo o phahameng), palo e phahameng ea HPMC e ka sebelisoa, hangata 0.8% -1.5%. Sepheo sa li-putty powders tsena ke ho ntlafatsa ho khomarela, ho hanyetsa ho phatloha le ho boloka metsi.

 

Motheo oa ho lokisa palo ea tlatsetso
Tikoloho ea tšebeliso: Haeba tikoloho ea kaho e na le mongobo o phahameng kapa mocheso o tlase, palo ea HPMC e eketsoang hangata e eketsoa ho ntlafatsa ho boloka metsi le ts'ebetso ea anti-cracking ea putty powder.
Mofuta oa putty: Mefuta e fapaneng ea phofo ea putty (joalo ka putty ea ka hare ea lebota, putty ea kantle ea lebota, putty e ntle, coarse putty, joalo-joalo) e na le litlhoko tse fapaneng tsa HPMC. Fine putty e hloka phello e matla haholoanyane, kahoo palo ea HPMC e sebelisitsoeng e tla ba holimo; athe bakeng sa putty e mahoashe, chelete e ekelitsoeng e kanna ea ba nyane.
Boemo ba motheo: Haeba setsi se le thata kapa se na le metsi a matla, ho ka 'na ha hlokahala ho eketsa palo ea HPMC e ekelitsoeng ho matlafatsa ho khomarela pakeng tsa putty le setsi.

 

Litlhokomelo tsa ho sebelisa HPMC

Qoba ho eketsa ho feteletseng: Le hoja HPMC e ka ntlafatsa ts'ebetso ea phofo ea putty, HPMC e feteletseng e tla etsa hore phofo ea putty e be thata haholo le e thata ho e haha, esita le ho ama lebelo la ho omisa le boima ba ho qetela. Ka hona, palo ea ho eketsa e hloka ho laoloa ho latela litlhoko tse khethehileng.

 

Motsoako le li-additives tse ling: HPMC e atisa ho sebelisoa hammoho le lisebelisoa tse ling tse kang phofo ea rabara, selulose, joalo-joalo Haeba e sebelisoa hammoho le li-thickeners tse ling kapa lisebelisoa tsa ho boloka metsi, tlhokomelo e lokela ho lefshoa ho phello ea synergistic pakeng tsa bona ho qoba likhohlano tsa ts'ebetso.

 

Ho tsitsa ha lintho:HPMCke ntho e qhibilihang ka metsing. Ho eketsa ho feteletseng ho ka etsa hore phofo ea putty e monye mongobo mme e senyehe nakong ea polokelo. Ka hona, nakong ea tlhahiso le polokelo, palo ea HPMC e sebelisitsoeng e lokela ho nkoa e le ho netefatsa botsitso ba putty powder tlas'a maemo a tloaelehileng a polokelo.

 

Ho eketsa HPMC ho putty powder ho ka ntlafatsa haholo ts'ebetso ea eona, haholo-holo mabapi le ts'ebetso ea kaho, ho boloka metsi le ho hanyetsa ho phatloha. Ka kakaretso, palo ea tlatsetso ea HPMC e pakeng tsa 0.3% le 1.5%, e lokisoang ho ea ka litlhoko tsa mefuta e sa tšoaneng ea putty powder. Ha u e sebelisa, hoa hlokahala ho leka-lekanya phello ea eona e teteaneng le litlhoko tsa kaho ho qoba liphello tse sa hlokahaleng tse bakoang ke tšebeliso e feteletseng.
