1. Khetha mofuta o nepahetseng oa HPMC bakeng sa kopo ea hau: HPMC e fumaneha ka limaraka tse fapaneng le maemo a viscosity ho latela botenya, sekhahla sa phallo le nako e behiloeng e hlokoang ke sehlahisoa.Etsa bonnete ba hore u khetha kereiti ea HPMC e lumellanang le litlhoko tsa hau tse ikhethileng.
2.
