He aha te Hydroxyethyl cellulose?

Ko te Hydroxyethyl cellulose (HEC) he ma, he kowhai marama ranei, he hongi, he kikokore, he paura totoka, he mea hanga ma te tauhohenga whakaeera o te cellulose kawakore me te ethylene oxide (te chlorohydrin ranei).
1. Tohutohu
1.1 taapiri tika i te wa whakaputa

1. Taapirihia he wai ma ki roto i te peere nui e mau ana ki te whakaranu kutikuti teitei.

2. Me timata ki te whakaoho i te tere iti, ka ata tatari i te hydroxyethyl cellulose ki roto i te otinga.

3. Whakakorikori tonu kia ruku nga matūriki katoa.

4. Kātahi ka tāpirihia he māngai antifungal, tāpiritanga kawakore pēnei i te poaka, he awhina whakamarara, he wai haukini.

5. Oho kia rewa katoa te hydroxyethyl cellulose (ka tino piki te pokey o te otinga) i mua i te taapiri i etahi atu waahanga ki roto i te tauira, ka huri kia oti ra ano te hua.

1.2 Kua whakaritea me te waipiro whaea

Ko tenei tikanga ko te whakarite i te waipiro whaea me te kukū teitei i te tuatahi, katahi ka taapiri atu ki te peita taherapa. Ko te painga o tenei tikanga he nui ake te ngawari, ka taea te taapiri tika ki te peita kua oti, engari me penapena pai. He rite nga hikoi ki nga Hipanga 1-4 i roto i te Tikanga 1, ko te rereketanga ko te kore he take ki te whakaoho kia rewa katoa ki roto i te wairewa viscous.

2.Porridge mo te phenology
I te mea ko nga whakarewa waro he whakarewa rawakore mohydroxyethyl cellulose, ka taea te whakamahi i enei whakarewa pararopi ki te whakarite i te pareti. Ko nga wairewa pararopi e whakamahia nuitia ana ko te wai pararopi penei i te ethylene glycol, propylene glycol me nga mea hanga kiriata (pērā i te ethylene glycol, diethylene glycol butyl acetate ranei) i roto i te hanga peita. He ngoikore hoki te wai tio, no reira ka whakamahia tahi te wai tio me nga wai pararopi hei taka pareti. Ko te hydroxyethyl cellulose o te pāreti ka taea te taapiri tika ki te peita, kua wehea te hydroxyethyl cellulose me te pupuhi i roto i te pareti. Ina tapirihia ki te peita, ka memeha tonu, ka mahi ano hei whakakaha. Whai muri i te taapiri, me whakaoho tonu kia rewa te hydroxyethyl cellulose me te rite. Ko te tikanga, ka mahia te pareti ma te whakaranu i nga wahanga e ono o te whakarewa pararopi, te wai hukapapa ranei me tetahi waahanga o te hydroxyethyl cellulose. I muri tata ki te 6-30 meneti, ka whakamarohia te hydroxyethyl cellulose ka tino pupuhi. I te raumati, he nui rawa te pāmahana o te wai, no reira kaore e pai ki te whakamahi i te pāreti.
3.Apure tono

Hydroxyethyl cellulose Ka whakamahia hei whakapiringa, surfactant, hei whakamarumaru colloidal, dispersant, etc.
He maha nga momo tono mo te peita, te peita, te muka, te tae, te hanga pepa, te whakapaipai, te pesticides, te tukatuka kohuke, te hinu whakaora hinu, me te rongoa.

1. Hydroxyethyl cellulose te nuinga whakamahia rite te thickener, māngai tiaki, whakapiringa, stabilizer me te tāpiritanga mo te faaineineraa o te whakaehunga, tiēre, hinu, hinu, horoi kanohi, suppository me te papa, a ka whakamahia ano hoki rite wai hydrophilic rā me te kōhiwi Materials, whakarite o momo matrix-momo-tuuturu-tuku takahanga, a ka taea hoki te whakamahi hei whakapumau i te kai.

2. Hydroxyethyl cellulose Ka whakamahia hei kaihoko rahi i roto i te ahumahi kakano, me te awhina mo te honohono, te matotoru, te whakaemulsifying, me te whakapumautanga i roto i te waahanga hiko me te ahumahi marama.

3. Ka whakamahia hei whakamaroke me te whakaheke wai mo te wai keri wai me te wai oti, a ka kitea te hua o te matotoru i roto i te wai keri tote. Ka taea hoki te whakamahi hei whakaheke wai mo te puna hinu sima. Ka taea te hono-whakawhiti ki nga katote whakarewa polyvalent hei hanga i te reera.

4. Ka whakamahia te hua Hydroxyethyl cellulose hei dispersant mo te polymerization o te wai-a-wai-a-wai-a-te-wai-a-te-wai-a-waa, te polystyrene me te polyvinyl chloride, me etahi atu ma te pakaru. Ka taea hoki te whakamahi hei kaitao whakaehunga i roto i te ahumahi peita, he hygrostat i roto i te ahumahi hiko, he anticoagulant ciment me te makuku pupuri i roto i te ahumahi hanga. Ko te whakakoi i te ahumahi karaima me te whakapiringa toothpaste. Kei te whakamahia nuitia ki te ta me te waikano, nga kakano, te hanga pepa, te rongoa, te akuaku, te kai, te hikareti, te pesticides me te patu ahi.

5. Ka rite ki te surfactant, colloidal māngai tiaki, emulsification stabilizer mo vinyl pūhaumāota, vinyl acetate me ētahi atu whakaehunga, me te tāherapa tackifier, dispersant, dispersion stabilizer, me ētahi atu whakamahia whānuitia i roto i coatings, muka, tae, pepa, Paku, rongoā, patu patukīrea. , me etahi atu He maha ano nga whakamahinga mo te torotoro hinu me te ahumahi miihini.

6. Ko te Hydroxyethyl cellulose he kaha te mata, he whakapakeke, he whakatarewa, he here, he whakaemulsifying, he hanga kiriata, he marara, he pupuri wai me nga mahi tiaki i roto i nga mahi rongoa totoka me te wai.

7. Ka whakamahia hei dispersant polymeric mo te whakamahi petroleum wai-based gel fracturing wai, polyvinyl chloride me te polystyrene. Ka taea hoki te whakamahi hei whakakao whakaehunga i roto i te ahumahi peita, he anticoagulant ciment me te makuku pupuri i roto i te umanga hangahanga, he kaikoi me te toothpaste adhesive i roto i te ahumahi uku. Kei te whakamahia nuitia i roto i nga mara ahumahi penei i te ta me te tae, te kakano, te hanga pepa, te rongoa, te akuaku, te kai, te hikareti me te pesticides.
