Ubwoko bwa hydroxypropyl methylcellulose

1. Amazi arimo ni menshi cyane, bivamo ibintu bike cyane, bihwanye no kugabanya ubukana bwumuti.
2. Ubukonje buri hasi, kandi ibimenyetso bimwe byerekana ububobere ntibihuye nubwiza nyabwo.
3. Kangura na nyuma yo kongeramo ibiyigize, bitabaye ibyo bizashyirwa hejuru, binanutse hejuru kandi binini munsi.
4. PH agaciro k'amazi: Niba agaciro ka PH k'amazi karenze 8, kabone niyo kongerwamo imbaraga, ntigishobora gukemura vuba vuba.(Ariko ntibizatinda nkamasaha 20).Niba pH agaciro k'amazi kari munsi ya 6.5, irashobora gukangurwa na nyuma yo kongeramo ibikoresho.Ariko birasaba kandi igihe runaka cyo gushonga.Iki gihe kiracyafitanye isano nagaciro ka pH.Hasi pH, umwanya muremure.Birasabwa kongeramo mumazi adafite aho abogamiye, hanyuma ugahindura agaciro ka pH kuri alkaline, kandi bizahita bikora ibintu bihoraho.Birumvikana, muri rusange ntabwo hakenewe guhinduka bidasanzwe mugukoresha nyabyo, nibindi bikoresho byinshi bizahita byongera agaciro ka pH.
