(2) Qara daidaito da danko na turmi
Lokacin da Drincell® ne ƙara zuwa turmi a matsayin mai kauri, zai kara dacewa da daidaito da danko turmi, yin turmin da aka more ragi da rage asarar ruwa. Musamman a cikin yanayin ƙasa na bushewar ƙasa, tasirin tasirin HPMC yana taimakawa haɓaka aikin turmin da ke motsa jiki.
(3) Ingantaccen kwanciyar hankali na turmi
HPMC na iya haɓaka haɗin gwiwar turmi da haɓaka kwanciyar hankali na turmi ta hanyar huldar ta hanyar motsa jiki. Wannan kwanciyar hankali yana ba da damar danshi na turɓudin da za'a kiyaye tsakanin barbashin ciminti na dogon lokaci, don ta tabbatar da cikakken rijiyar da ruwa da ruwa da haɓaka ƙarfin turmi da ruwa da haɓaka ƙarfin turmi.
5. Sakamakon HPMC a aikace-aikace aikace-aikace
