Ho boloka metsi ke bokhoni ba ntho ho tšoara kapa ho boloka metsi. Tabeng ea HPMC, ke bokhoni ba ho monya le ho boloka metsi, haholo lithabeng tsa Greerous. Ho boloka metsi ka HPMC ho angoa ke lintlha tse 'maloa, ho kenyelletsa le pono ea eona, pono, mocheso le ph.
E 'ngoe ea lintlha tsa sehlooho tse amang metsi a ho boloka metsi ho HPMC ke ho tsepamisa maikutlo. HPMC e na le bokhoni bo phahameng ba metsi meahong e phahameng.

Ntho e 'ngoe e amang bolokolohi ba metsi ka HPMC ke pono. Lits'oants'o li bolela ho hanyetsa ha ho hanyetsa hpmc. Ke pono e phahameng haholo, matla a tsitsitseng a metsi. Leha ho le joalo, Vscosity e phahameng e ka hlahisa monyetla o moholo oa ho nka khato e fosahetseng, e ka amang tšebetso e mpe ea sehlahisoa.

Mocheso o boetse o ama ho bolokoa ka metsi ka hpmc. Boemong bo phahameng, HPMC e na le boholo ba metsi a tlase. Sena ke hobane mocheso o phahameng o ka baka ho theoha ha maqeba, ho baka HPMC ho lahleheloa ke matla a ho boloka metsi. Ho fapana le moo, mocheso o tlase o khothalletsa ho boloka metsi, ho etsa HPMC motsoako o loketseng bakeng sa lihlahisoa tse hlokang ho boloka metsi, tse kang lipelaelo le lits'oants'o.
