Siyazi ukuthi i-hydroxypropyl methylcellulose iyimpushana ekamelweni lokushisa, futhi impushana ifana ngokufanayo, kodwa uma uyibeka emanzini, amanzi azoba ne-viscous ngalesi sikhathi, Futhi ngezinga elithile le-viscosity, singayibona kahle. ngokusebenzisa izici ze-hydroxypropyl methylcellulose, kanye nezindawo zokwakha ezijwayelekile zizojwayelana nesici sayo, vumela yonke i-putty powder ihlangane ukuze kwandiswe Ukunamathela phakathi i-putty powder kanye nodonga olungaphezulu, ngakho-ke yimiphi imininingwane okufanele inakwe lapho wengeza i-hydroxypropyl methylcellulose ku-putty powder?
Uma noma iyiphi impushana isizokwenziwa isixazululo, kufanele kube nemfuneko ethile yomthamo, futhi ukusetshenziswa kwe-hydroxypropyl methylcellulose nakho. Uma wenza isisombululo esixubene ne-putty powder, isilinganiso saso ngokuvamile sincike ekushiseni kwangaphandle, imvelo, Izinga le-calcium yomlotha wendawo lihlobene eduze nalezi zici. Ngokuvamile, ezinye izixazululo ze-putty powder zidinga ukulungiswa. Ngokuvamile, abantu bazosebenzisa i-hydroxypropyl methylcellulose phakathi kuka-4 kg no-5 kg, kodwa ngokuvamile inani elisetshenziswa ebusika lingaphezulu kwalelo lasehlobo. Kufanele libe lincane. Uma wenza isixazululo esixubile, ungasifingqa ngokucophelela.
Ngaphezu kwalokho, lapho isisombululo sengxube silungiswa ezifundeni ezahlukene, umthamo nawo uhlukile. Isibonelo, ukulungisa isisombululo endaweni ethile yaseBeijing, ngokuvamile kuyadingeka ukwengeza ama-5 kg we-HPMC. Kodwa lesi samba senzelwe ihlobo, kanti ebusika sibe ngaphansi ngo-0.5 kg; kodwa ezindaweni ezifana ne-Yunnan, lapho wenza ikhambi, ngokuvamile kudingeka kuphela ukubeka i-3 kg - 4 kg ye-HPMC, umthamo Ingaphansi kakhulu kune-Beijing, futhi imvelo ihlukile, futhi kuzoba nokuhluka kwenani lemvelo.
