Ko nga whakamahinga matua me nga rereketanga o te hydroxypropyl methylcellulose HPMC me te hydroxyethyl cellulose HEC

Carboxymethyl cellulose, hydroxypropyl methyl cellulose, me te hydroxyethyl cellulose me te monosodium glutamate ahumahi e whakamahia ana i te nui rawa atu.Ko te tino uaua ki te wehewehe i enei momo cellulose e toru ko te hydroxypropyl methylcellulose me te hydroxyethyl cellulose.Kei raro nei ka wehewehea enei momo cellulose e rua ma te whakamahi me te mahi.

I te mea he surfactant kore-katote, kei a hydroxyethyl cellulose nga taonga e whai ake nei hei taapiri i nga mahi o te aukati, te matotoru, te marara, te maanu, te honohono, te hanga kiriata, te pupuri wai me te whakarato colloid tiaki:

1. Ko te HEC ake he katote-kore, ka taea te noho tahi me te tini o etahi atu polymers wairewa-wai, surfactants, me nga tai.He tino pai rawa atu ki te whakakao i te colloidal mo nga rongoā kei roto i nga electrolytes teitei.

2. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea kino rawa atu, engari ko te kaha o te colloid tiaki te kaha.

3. Ko te kaha o te pupuri i te wai e rua ake te teitei o te methyl cellulose, a he pai ake te whakahaere o te rere.

4. He wairewa te HEC i roto i te wai wera, i te wai matao ranei, karekau e pupuhi i te wera nui, te koropuputanga ranei, na te mea he maha nga ahuatanga o te wairewa me nga ahuatanga pokey, me te waiariki kore.

Te whakamahi HEC: te nuinga o te whakamahia hei whakamaroke, hei maataki tiaki, hei whakapiri, hei whakapumau me te whakarite o te whakaehunga, te tiēre, te hinu, te hinu, te maamaa o te kanohi.

Hydroxypropyl methylcellulose (HPMC) tono whakataki:

1. Ahumahi whakakikorua: Kei te whakamahia hei whakamaaratanga, hei whakamararatanga me te whakapumau i roto i te umanga whakakikorua, a he pai te hototahi ki roto i te wai, i nga whakarewa pararopi ranei.Hei tango peita.

2. Te ahumahi hanga karamiki: Kei te whakamahia nuitia hei here i roto i te hanga o nga hua uku.

3. Ētahi atu: Kei te whakamahia whānuitia tenei hua i roto i te hiako, hua pepa, hua me te tiaki huawhenua me ahumahi pueru, etc.

4. Ink tā: Kei te whakamahia te reira rite te thickener, dispersant me stabilizer i roto i te ahumahi mangumangu, a he pai hototahi i roto i te wai whakarewa organic ranei.

5. Kirihou: whakamahia rite hanga kaihoko tuku, ngohengohe, whakahinuhinu, etc.

6. Polyvinyl chloride: Kei te whakamahia hei dispersant i roto i te hanga o te polyvinyl chloride, a ko ia te kaihoko awhina matua mo te whakarite i te PVC ma te whakakore i te polymerization.te

7. Ahumahi hanga: Ka rite ki te kaihoko pupuri wai me te aukati o te slurry kirikiri sima, ka taea e ia te pupuhi i te kumete.I roto i te raima, i te gypsum, i te paura putty, i etahi atu mea hanga whare ranei hei here ki te whakapai ake i te horahanga me te whakaroa i te wa mahi.Ka taea te whakamahi hei whakapiri tile, mapere, whakapaipai kirihou, whakapiri whakakaha, ka taea hoki te whakaiti i te nui o te ciment.Ko te mahi pupuri wai o te HPMC ka aukati i te pakaru mai i te pakaru na te mea he tere rawa te whakamaroke i muri i te tono, me te whakanui ake i te kaha i muri i te whakapakeke.
