Whakaahuatanga Hua:
Ko te Methyl Hydroxyethyl Cellulose (MHEC) he ether cellulose kore-ionic e whakamahia nuitia ana i roto i nga taonga hanga. Ka taea te rewa i roto i te wai wera, matao ranei hei hanga i tetahi otinga maramara me te tino pokey. He rite tonu nga ahuatanga o te methyl hydroxyethyl cellulose me te methylcellulose, engari ko te noho o te hydroxyethyl ka nui ake te wairewa MHEC cellulose ki te wai, he pai ake te hototahi o te otinga ki te tote, he teitei ake te pāmahana whakahiato.
Taupānga:
Ko te paura cellulose MHEC e whakamahia nuitia ana i roto i te ahumahi whare. Hei tauira, ka taea te whakamahi i roto i te whakapiri taera, te whakakii hono, te moata-whaiaro, te raima, te koti rei, te peita me te paninga, me etahi atu hei ether cellulose kore-ionic, he pai te whakapumautanga o te paura HMEC me te whakakaha i te peita, ka taea e te peita te whakaputa i te aukati kakahu pai. Ko te whakahinuhinu o te MHEC cellulose ka taea te whakapai ake i te mahi moata (penei i te whakapai ake i te kaha here o te kumete, te whakaiti i te whakauru wai, me te whakarei ake i te anti-sag o te moata), he mea pai ki te whakapai ake i te pai o te mahi.
Engari mo te ahumahi hanga, ka whakamahia ano te methyl hydroxyethyl cellulose i roto i te ahumahi kai, nga matū o ia ra, me etahi atu mara. I roto i te ahumahi kai, ka whakamahia te HEMC cellulose hei whakapiri, hei whakaehunga, hei hanga kiriata, hei whakapakeke, hei whakatarewa, hei whakamarara, hei pupuri i te wai, me etahi atu. I roto i nga matū o ia ra, ka whakamahia hei taapiri mo te toothpaste, te whakapaipai, me te horoi.
