01.Hydroxyethyl Cellulose
Ka rite ki te surfactant kore-katote, hydroxyethyl cellulose ehara i te mea ko nga mahi anake o te whakatarewa, te matotoru, te whakamarara, te rere, te honohono, te hanga kiriata, te pupuri wai me te whakarato colloid tiaki, engari kei a ia ano nga taonga e whai ake nei:
1. He wairewa te HEC i roto i te wai wera, i te wai matao ranei, karekau e heke i te wera nui, i te koropupuputanga ranei, na reira he whanuitanga o te wairewa me nga ahuatanga pokey, me te waiariki kore;
2. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea tino kino, 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.
Whakatupato ina whakamahi:
I te mea he paura, he totoka ranei te cellulose hydroxyethyl cellulose, he ngawari ki te hapai me te memeha i roto i te wai mena ka tuhia nga take e whai ake nei.
1. I mua, i muri i te taapiri i te hydroxyethyl cellulose, me whakaoho tonu kia tino marama, kia marama te otinga.
2. Me ata tatari ki roto i te ipu whakaranu. Kaua e whakauru tika i te hydroxyethyl cellulose kua hanga hei kapia, hei poipoi ranei ki roto i te oko whakaranu i te nui, i te tika ranei.
3. Ko te pāmahana wai me te uara pH o te wai he hononga nui ki te whakakorenga o te hydroxyethyl cellulose, no reira me aro nui ki a ia.
4. Kaua rawa e tapiri etahi matū kawakore ki te ranunga i mua i tehydroxyethyl celluloseka whakamahana te paura ki te wai. Ko te whakanui ake i te uara PH i muri i te whakamahana he awhina mo te whakakore.
Whakamahi HEC:
1. I te nuinga o te wa e whakamahia ana hei maatete whakamaarama, hei whakamarumaru, hei whakapiri, hei whakapumau me te taapiri mo te whakarite i te emulsion, te gel, te hinu, te hinu, te kaihoko horoi kanohi, te suppository me te papa, ka whakamahia ano hoki hei reera hydrophilic, nga rauemi angaahi, te whakarite i nga whakaritenga tuku-a-iwi, ka taea hoki te whakamahi hei whakapumau i te kai.
2. Kei te whakamahia hei kaihoko rahi i roto i te ahumahi kakano, te honohono, te matotoru, te emulsifying, te whakapumau me etahi atu awhina i roto i nga waahanga hiko me nga waahanga marama.
3. Ka whakamahia hei whakamatao me te whakaheke filtrate mo te wai keri wai me te wai otinga, a ka kitea te kaha o te whakakaha i roto i te wai keri wai tote. Ka taea hoki te whakamahi hei kaihoko whakahaere mate wai mo te sima puna hinu. Ka taea te hono-whakawhiti ki nga katote whakarewa polyvalent hei hanga ra.
5. Ka whakamahia tenei hua hei dispersant mo te wai-wai-wai-a-te-wai-a-raa i nga wai pakaru, te polystyrene me te polyvinyl chloride i roto i te hanga hinu pakaru. Ka taea hoki te whakamahi hei whakakao whakaehunga i roto i te ahumahi peita, te haumākū parenga tairongo i roto i te ahumahi hiko, ciment coagulation inhibitor me te makuku pupuri kaihoko i roto i te ahumahi hanga. Ko te whakakikorua me te whakapiri niho mo te ahumahi uku. Kei te whakamahia nuitia ki te ta me te tae, te kakano, te hanga pepa, te rongoa, te akuaku, te kai, te hikareti, te pesticides me te patu ahi.
02.Hydroxypropyl Methyl Cellulose
1. Ahumahi whakakikorua: Ka rite ki te thickener, dispersant me te stabilizer i roto i te ahumahi paninga, he pai te hototahi i roto i te wai whakarewa organic 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 niao 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.
7. Ahumahi hanga: Hei kaihoko pupuri wai me te aukati mo te kumete ciment, he papu te moata. 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 tira karaima, te mapere, te whakapaipai kirihou, hei whakanui i te whakapiri, ka taea hoki te whakaiti i te nui o te ciment. Ko te pupuri wai o te hydroxypropyl methylcelluloseHPMCKa taea te aukati i te slurry kia pakaru na te tere rawa o te whakamaroke i muri i te tono, me te whakarei ake i te kaha i muri i te whakapakeke.
