Thepa ea HPMC e sebelisitsoeng kahong
1. Ho boloka metsi
Hydroxypropyl methyl cellulose HPMC bakeng sa kaho e thibela ho monngoa ho feteletseng ha metsi ke substrate, 'me metsi a lokela ho bolokoa ka har'a plaster ka hohle kamoo ho ka khonehang nakong ea ho phethoa ha gypsum solidification. Thepa ena e tsejoa e le ho boloka metsi, 'me e lekana le viscosity ea moaho o khethehileng oa hydroxypropyl methyl cellulose HPMC tharollo ka har'a stucco, ho phahamisa viscosity ea tharollo, ho phahamisa matla a ho boloka metsi.
Hang ha metsi a ntse a eketseha, matla a ho boloka metsi a fokotseha, hobane metsi a ntseng a eketseha a ile a hlapolla kaho ea hydroxypropyl methyl cellulose HPMC tharollo, e leng se bakang ho fokotseha ha viscosity.
2. Ho hanyetsa ho sag
Stucco e hanyetsanang le ho phalla le ho fanyeha e lumella sehahi hore se sebelise seaparo se teteaneng ntle le phallo e otlolohileng, e leng se bolelang hape hore stucco ka boeona ke thixotropic, ho seng joalo e thellela fatše nakong ea kaho.
3. Fokotsa viscosity, kaho e bonolo
Ka ho kenyelletsa mefuta e fapaneng ea meaho e khethehileng ea hydroxypropyl methyl cellulose lihlahisoa tsa HPMC, viscosity e tlase le kaho e bonolo e ka fumanoa ho plaster ea gypsum, ho sebelisoa moaho o tlase oa viscosity o inehetseng hydroxypropyl methyl cellulose HPMC, viscosity e batlang e fokola le kaho e bonolo, leha ho le joalo, moaho o tlase oa viscosity o inehetseng. hydroxypropyl methyl cellulose Bokhoni ba ho boloka metsi ba HPMC bo fokola, bo hloka ho phahamisa palo e eketsehileng.
4. Sekhahla sa kholo ea bokhoni ba stucco
Bakeng sa palo e tsitsitseng ea seretse se omeletseng, ho na le chelete e ngata ho hlahisa molumo o phahameng oa seretse se metsi, se ka finyelloang ka ho eketsa metsi le li-bubble. Empa metsi a mangata le li-bubble li ka senya matla.
