7. Ntughari na nchedo
Ihe nkiri mkpuchi ahụ guzobere nke HPMC nwere ụfọdụ nguzogide na kemịkalụ, nke nwere ike ichebe mkpụrụ site na ihe na-emerụ ahụ na gburugburu ebe obibi. Dịka ọmụmaatụ, na mkpuchi nchebe maka osisi ma ọ bụ ọla, HPMC nwere ike ịkwalite ịdịte aka ma na-agbatị ndụ ọrụ ya.

8. Nchedo gburugburu na nchekwa
Dị ka ihe na-abụghị ihe na-adịghị mma na ebe obibi na gburugburu, HPMC na-ezute ihe akwụkwọ ndụ akwụkwọ ndụ chọrọ nke ụlọ ọrụ a na-akwụ ụgwọ. N'ọtụtụ mkpuchi mmiri, ọ nwere ike dochie ọnya ọdịbendị ọdịnala, belata ikuku nke ihe na-agbanwe agbanwe (Volu), ma melite gburugburu ebe a na-ewu ụlọ.

HPMC na-egwu ọrụ dị iche iche na mkpuchi. Ọ na-akpụ mkpụrụ osisi, sie ike, ngwa mgbakwunye na mmiri na-eme ka ọ bụrụ ihe dị mkpa na usoro mkpuchi.
