E kore e taea e te hydroxypropyl methylcellulose te kaha-nui te whakaputa i te cellulose tino teitei anake ma te whakakoi me te whakakapi hauota i roto i te hanga. I te nuinga o te waa, kaore e taea te whakahaere i te hanga o te cellulose kikorangi-nui i Haina. Heoi, ki te taea te whakauru i tetahi taputapu ine hāora ki roto i te ketere, ka taea te whakahaere i te hanga o tona pokey. I tua atu, i te whakaaro ki te tere whakakapi o te hauota, he ngawari ki te whakaputa i nga hua-nui-nui ahakoa te ahua o te hau o te punaha. Ae ra, he mea nui ano te tohu polymerization o te miro parakore. Ki te kore e mahi, katahi ka mahi me te hononga hydrophobic. He kaihoko hononga kei tenei rohe i Haina. He aha te ahua o te kaihoko hononga hei whiriwhiri ka whai mana nui ki te mahi o te hua whakamutunga.
Ko te whakawhiti marama o te hydroxypropyl methylcellulose te nuinga o nga paanga e whai ake nei:
1. Te kounga o nga rauemi mata.
2. Ko te painga o te whakamaaramatanga.
3. Tukatuka ōwehenga.
4. Te ōwehenga o ngā whakarewa.
5. Te awenga whakaheke.
Ko te toenga o te hāora kei roto i te kōhua ka paheke te cellulose me te whakaiti i te taumaha ngota, engari he iti te toenga o te hāora, mena ka hono noa nga ngota ngota kua pakaru, ka ngawari te pokey teitei. Heoi ano, he hononga kaha te taumata o te wai kukū ki te taumata o te hydroxyproline. Ko etahi o nga wheketere e hiahia ana ki te whakaheke i te utu me te utu, kaore e hiahia ki te whakanui ake i nga ihirangi o te hydroxyproline kia kore ai te kounga e eke ki te taumata o nga hua ka puta ki waho. Ko te taumata tiaki o te hua e pa ana ki te phenol wai, engari i te nuinga o te waa, ka whakatauhia e te tukanga tauhohenga tona tohu tiaki, te ōwehenga o te alkali, te methyl chloride me te propylene oxide, te kukū o te alkali me te ōwehenga o te wai me te miro e whakatau ana i tana mahi. .
