He monosodium glutamate ahumahi, carboxymethyl cellulose, hydroxypropyl methyl cellulose, mehydroxyethyl cellulose, ko nga mea e tino whakamahia ana.I roto i nga momo cellulose e toru, ko te tino uaua ki te wehewehe ko te hydroxypropyl methylcellulose me te hydroxyethyl cellulose.Me wehewehe enei momo cellulose e rua ma o raatau whakamahinga me o raatau mahi.
I te mea he surfactant kore-katote, kei a hydroxyethyl cellulose nga ahuatanga e whai ake nei hei taapiri mo te whakatārewa, te matotoru, te marara, te rere, te honohono, te hanga kiriata, te pupuri wai me te whakarato colloids whakamarumaru:
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 e mau ana nga otinga electrolyte kukū 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 colloid tiaki te kaha 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 pāmahana teitei, te koropuputanga ranei, na reira he maha nga ahuatanga o te whakarewatanga me nga ahuatanga pokey, tae atu ki te waiariki kore.
Te whakamahi HEC: te nuinga o te whakamahia hei maataki whakakaha, hei maataki whakamarumaru, hei whakapiri, hei whakapumau me te whakarite whakaehunga, tiēre, hinu, hinu, horoi kanohi.
Hydroxypropyl methylcellulose (HPMC) tono whakataki:
1. Ahumahi whakakikorua: hei whakapouri, whakamararatanga me te whakapumau i roto i te umanga whakakikorua, he pai te hototahi ki roto i te wai, i nga whakarewa pararopi ranei.hei tango peita.
2. Te hanga uku: 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, ahumahi hua pepa, hua me te tiaki huawhenua me te ahumahi pueru, etc.
4. Ink tā: rite te thickener, dispersant me stabilizer i roto i te ahumahi mangumangu, he pai hototahi i roto i te wai whakarewa organic ranei.
5. Kirihou: whakamahia rite mold release agent, softener, lubricant, 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.
7. Ahumahi hanga: Ka rite ki te kaihoko pupuri wai me te retarder mo te slurry kirikiri sima, hanga te reira i te slurry onepu pumpable.Ka whakamahia hei here mo te whakapiri raima, te gypsum, te paura putty me etahi atu mea hanga whare hei whakapai ake i te horahanga me te whakaroa i te waa mahi.Ka whakamahia hei whakapiri mo te tile karamu, mapere, whakapaipai kirihou, hei whakanui i te whakapiri, ka taea hoki te whakaiti i te nui o te ciment.Ka taea e te pupuri wai o HPMC te aukati i te slurry mai i te pakaru na te mea he tere rawa te whakamaroke i muri i te tono, me te whakarei ake i te kaha i muri i te whakapakeke.
