Kei reira ngā monosodium glutamate ahumahi, te carboxymethyl cellulose, te hydroxypropyl methyl cellulose, mete hauwaitoiretiri pūtau, koinei ngā mea e whakamahia nuitia ana. I roto i ngā momo cellulose e toru, ko te mea tino uaua ki te wehewehe ko te hydroxypropyl methylcellulose me te hydroxyethyl cellulose. Me wehewehe tātou i ēnei momo cellulose e rua mā ō rātou whakamahinga me ā rātou mahi.
Hei matū horoi kore-ionic, kei te hydroxyethyl cellulose ēnei āhuatanga e whai ake nei, hei tāpiri atu ki te whakatārewatanga, te whakamātotorutanga, te whakamararatanga, te whakapūmautanga, te herea, te hanga kiriata, te pupuri wai me te whakarato i ngā colloid tiaki:
1. Ko te HEC tonu he kore-ionic, ā, ka taea te noho tahi me te whānuitanga o ngā polymer wairewa-wai, ngā surfactants, me ngā tote. He whakamātotoru colloidal pai rawa atu kei roto ngā otinga electrolyte kukū teitei.
2. Ki te whakaritea ki te methyl cellulose me te hydroxypropyl methyl cellulose kua mōhiotia, ko te kaha marara o HEC te mea kino rawa atu, engari ko te colloid tiaki te mea tino kaha.
3. E rua ngā teitei ake o te kaha pupuri wai i tō te methyl cellulose, ā, he pai ake te whakahaere i te rere.
4. Ka wairewa te HEC i te wai wera, i te wai matao rānei, ā, kāore e pupū ake i te pāmahana tiketike, i te wai kohua rānei, nō reira he whānuitia ōna āhuatanga wairewa me te matotoru, tae atu ki te whakapūkara kore-wera.
Te whakamahinga o te HEC: e whakamahia whānuitia ana hei whakamātotoru, hei tiaki, hei piripiri, hei whakaū, hei whakarite i te whakaemulsion, te tiēre, te hinu whakahinuhinu, te hinu whakamāmā kanohi.
Whakataki tono Hydroxypropyl methylcellulose (HPMC):
1. Te umanga paninga: hei whakamātotoru, hei whakamarara me hei whakaū i roto i te umanga paninga, he pai te hototahi ki te wai, ki ngā whakarewa rauropi rānei. Hei tango peita.
2. Te hanga uku: e whakamahia whānuitia ana hei here i roto i te hanga hua uku.
3. Ētahi atu: E whakamahia whānuitia ana hoki tēnei hua i roto i te hiako, te ahumahi pepa, te tiaki hua me te huawhenua me te ahumahi kakahu, me ētahi atu.
4. Tānga waituhi: hei whakamātotoru, hei whakamarara me hei whakau i roto i te umanga waituhi, he pai te hototahi ki te wai, ki ngā whakarewa waro rānei.
5. Kirihou: whakamahia hei kaiwhakawātea pokepokea ai, hei whakangawari, hei hinu whakahinuhinu, me ētahi atu.
6. Polyvinyl chloride: E whakamahia ana hei mea whakamarara i roto i te hanga o te polyvinyl chloride, ā, koia te kaihoko āwhina matua mō te whakarite i te PVC mā te whakapūhui whakatārewatanga.
7. Ahumahi hanga: Hei mea pupuri wai, hei mea whakaroa hoki i te paru sima onepu, ka taea te papu i te paru onepu. Ka whakamahia hei here i roto i te whakapiri paraki, te gypsum, te paura putty, me ētahi atu rauemi hanga hei whakapai ake i te horapa me te roa o te wā mahi. Ka whakamahia hei whakapiri mō ngā taera uku, te māpere, te whakapaipai kirihou, hei whakarei ake i te whakapiri, ā, ka taea hoki e ia te whakaiti i te nui o te sima. Mā te pupuri wai o te HPMC ka ārai i te pakaru o te paru nā te tere rawa o te maroke i muri i te paninga, ā, ka whakarei ake i te kaha i muri i te whakapakeketanga.
