Ukongeza kancinci kancinci: Yongeza amanzi kancinci kancinci ngelixa uxuba ukuze uphephe ukuhlangana. Qala ukuxuba ngamanzi amancinci uze wongeze amanye xa kufuneka.
Ukujonga Ukungaguquguquki: Jonga ukuhambelana kwesamente ukuze kufezekiswe ukusebenza okufunekayo. Ubungakanani bamanzi ongezelelweyo kufuneka bulawulwe ukuze kuthintelwe ukuxutywa kakhulu, okunokwenza umxube ube buthathaka.
Ixesha lokuxuba:
Ukuxuba kokuqala: Xuba izithako imizuzu emi-3-5 de kufumaneke umxube ofanayo.
Ixesha Lokuma: Vumela umxube uhlale imizuzu embalwa. Eli xesha lokuma linceda ekusebenzeni ngokupheleleyo kwe-HPMC, liphucula ukusebenza kwayo.
Ukuxuba kokugqibela: Xuba kwakhona imizuzu eli-1-2 ngaphambi kokuba uyisebenzise.
3.3 Iingcebiso zokusebenzisa
Ubushushu kunye nokufuma: Lungisa umxholo wamanzi kunye nexesha lokuxuba ngokweemeko zomoya. Ubushushu obuphezulu okanye ukufuma okuphantsi kunokufuna amanzi ongezelelweyo okanye ixesha lokuvula elincitshisiweyo.
Ukucoceka kwezixhobo: Qinisekisa ukuba izixhobo zokuxuba kunye nezikhongozeli zicocekile ukuthintela ungcoliseko kunye neziphumo ezingahambelaniyo.
4. Izinto Eziqwalaselwayo Nezokusombulula Iingxaki
4.1 Ukuphathwa kunye nokugcinwa
Iimeko Zokugcina: Gcina umgubo we-HPMC kwindawo epholileyo neyomileyo ukuthintela ukufunxwa nokuqhekeka komswakama.
Ixesha Lokugcinwa: Sebenzisa umgubo we-HPMC ngaphakathi kwexesha lokugcinwa ukuqinisekisa ukusebenza kakuhle. Jonga izikhokelo zomenzi ukuze ufumane iingcebiso ezithile zokugcina.
