Ts'ebetso ea ho Boloka Metsi le Molao-motheo oa Lijo tsa Chololus Ether HPMC e bapala karolo ea ho boloka metsi le ho hanyetsa Lintho tse kang mocheso oa moea, mocheso oa mocheso oa moea, lebelo la khatello le moea le tla ama sekhahla sa ho fetola mafura sa metsi le lihlahisoa tse thehiloeng sa gypsum. Ka hona, ka linako tse fapaneng, ho na le phapang e itseng ka litlamong tsa ho ikoetlisa ka metsing tsa lihlahisoa tse lekanang tsa lihlahisoa tsa HPMC. Ka setsing se tobileng, ho boloka metsi ho boloka metsi ha ho tšela ho ka fetoloa ka ho eketseha kapa ho fokotsa palo ea HPMC e kenyellelitsoe.
Ho boloka metsi ka mpeng ea tšepe e tlasa maemo a mocheso o phahameng ke pontšo ea bohlokoa ho khetholla boleng ba methyl cellengse ea methyl ether. Lihlahisoa tsa HPMC tsa HPMC tsa HPMC li ka rarolla bothata ba ho boloka metsi mochesong o phahameng. Linakong tse phahameng tsa mocheso, haholo libakeng tse chesang le tse omeletseng le kaho e nang le ts'ebetso e tšesaane le kaho e tšesaane ka lehlakoreng le letsatsi, ho hlokahala hpmc e phahameng haholo ea ho ntlafatsa metsi a slurry.
Hpmc ea boleng bo holimo e na le ntho e ntle haholo.

Ho boloka metsi ka hpmc ho angoa ke lintlha tse latelang:
1. Homogneity ea Cellulose Ether hpmc
HPMC ka mokhoa o hlakileng oa HPM
2. Mocheso oa mafura oa cellulose ether hpmc
Mocheso oa mafura o futhumetseng o phahame, sekhahla sa ho boloka metsi ho phahame; Che, ho fapana le moo, Lerata la ho boloka metsi le tlaase.
3. Viscosity of cellulose Ether hpmc
Ha liketsahalo tsa HPMC li ntse li eketseha, Sepole sa ho boloka metsi le hona hoa eketseha; Ha liketsahalo li fihla boemong bo itseng, keketseho ea lebelo la ho boloka metsi ho lula ho bata.
4. TLHOKOMELISO EA CELLULODE Ether HPMC
Ka ho fetisisa palo ea cellulose ether HPMM e kenyellelitsoeng, sekhahla sa ho boloka metsi le ho boloka metsi hantle ho ikoetlisa ka metsing. Karolong ea 0,25-0.6%, Lerata la ho boloka metsi le eketseha ka keketseho ea palo ea chelete; Ha chelete e eketsehileng e eketseha, mokhoa o ntseng o eketseha oa lebelo la ho boloka metsi butle butle butle butle.
