Carboxymethyl Cellulose
1. Whakamahia i roto i te keri hinu me te hau māori, te keri puna me ētahi atu kaupapa
① Ka taea e te paru kei roto i te CMC te hanga i te pakitara o te puna hei keke tātari angiangi, mārō hoki, he iti te uruhanga, ka whakaiti i te ngaronga wai.
② I muri i te tāpiri i te CMC ki te paru, ka taea e te taputapu keri te whiwhi i te kaha kutikuti tīmatanga iti, kia taea ai e te paru te tuku ngāwari i te hau kua takaihia ki roto, ā, i te wa ano, ka taea te maka tere i ngā paru ki roto i te poka paru.
③ He roa te wā e mau ai te paru keri, pērā i ētahi atu whakatārewatanga me ngā marara. Mā te tāpiri i te CMC ka pumau, ka roa ake hoki te wā e mau ai.
