Siyazi ukuthi i-hydroxypropyl methylcellulose iyi-powdery into etholakala ekamelweni lokushisa, futhi i-powder iyafana, kodwa uma uyibeka emanzini, amanzi azoba viscous ngalesi sikhathi, Futhi ngezinga elithile le-viscosity, singayibona kahle ngokusebenzisa izici ze-hydroxypropyl methylcellulose, futhi izindawo zokwakha ezijwayelekile ngokuvamile zizovumelana nesici esinjalo sayo, vumela yonke i-putty powder ihlangane ukuze kwandiswe ukunamathelana phakathi kwe-putty powder kanye nobuso bodonga, ngakho-ke yimiphi imininingwane okufanele inakwe lapho kungezwa i-hydroxypropyl methylcellulose ku-putty powder?
Uma noma iyiphi i-powder isizokwenziwa ibe yisisombululo, kumele kube nesidingo esithile somthamo, futhi ukusetshenziswa kwe-hydroxypropyl methylcellulose akuhlukile. Lapho wenza isisombululo esixubile nge-putty powder, umthamo waso ngokuvamile uncike ekushiseni kwangaphandle, indawo ezungezile, kanye nekhwalithi ye-calcium yomlotha yendawo ihlobene 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 liphakeme kunalelo lasehlobo. Kufanele libe lincane. Uma wenza isisombululo esixubile, ungasifingqa ngokucophelela.
Ngaphezu kwalokho, uma ikhambi lengxube lilungiswa ezindaweni ezahlukene, umthamo nawo uhlukile. Isibonelo, ukuze kulungiswe ikhambi esifundeni esithile saseBeijing, ngokuvamile kuyadingeka ukwengeza ama-5 kg e-HPMC. Kodwa leli nani liphinde libe lehlobo, futhi lingaphansi ngama-0.5 kg ebusika; kodwa ezindaweni ezifana neYunnan, lapho kwenziwa ikhambi, ngokuvamile kudingeka kufakwe ama-3 kg – 4 kg e-HPMC kuphela, umthamo ungaphansi kakhulu kuneBeijing, futhi indawo ihlukile, futhi kuzoba nomehluko enanini lemvelo.
