Kuchengeta kwemvura kwe cellulose ether

Cellulose ether is a inoshanda zvinhu zvinoshandiswa zvakanyanya mukuvaka, mushonga, chikafu, zvizoro uye zvimwe minda. Kuchengeta kwemvura kwayo ndeimwe yehunhu hwayo hwakakosha, kunyanya mukushandiswa kwezvinhu zvekuvaka zvakadai sevhu uye simende. Kuchengetwa kwemvura kunoreva kugona kwemheremelle ether kuti uwedzere kukiya mumucheka mushure mekunyorova mvura uye kudzivirira kurasikirwa nekunyorova nekukurumidza. Hunhu uhwu husingabatsire kungoita basa rekuvaka remashoko, asi zvakare rinoita basa rakakosha musimba rayo rekupedzisira uye kusimba.

Kuchengeta kwemvura kwemvura kwe cellulose ether
Cellulose ether ine yakasimba kwazvo hydrophilikuticity, iyo inobva kune yakakura nhamba yehydroxyl (-OOOH) mapoka mune yayo molecular chimiro. Mapoka eHydroxyl anogadzira nyore maHydrogen zvisungo zvine mamorekuru, achibvumira cellulose ether kuti awane mari uye chengetedza huwandu hwakawanda hwemvura. Mumhedzisiro mhinduro, cellulose ether mamorekuru anogona kuumba matatu emhando network, inokonzera kufambisa kwemvura uye kunoderedza mwero wemvura, nokudaro uchivandudza kuchengetwa kwemvura kwechinhu.

Cellulose ether inogona kugadzirisa huwandu hwayo hwemvura pasi pe tembiricha yakasiyana uye mamiriro ekuseka. Semuenzaniso, mumamiriro ekunze akanyanya, cellulose ether anogona kugadzirisa mwero wemvura nekuchinja zvavakaita, kudzivisa kupaza uye kurasikirwa nesimba kunokonzerwa nekurasikirwa kwemvura zvakanyanya muchinyorwa chekutanga chezvinyorwa.

Zvinhu zvinokanganisa Kuchengeta mvura

1. Degree rekutsiva (DS)

Dhigirii rekutsiva cellulose ether chinhu chakakosha chinokanganisa kuchengetwa kwemvura kwayo. Dhigirii rekutsiva rinoreva iyo degree kune iyo maHydroxyl mapoka muCellulose Molecule anotsiviwa nemapoka e-ether mapoka. Yakakwira iyo degree rekutsiva, iyo yepamusoro solubility yemvura uye nekuchengetwa kwemvura kwemvura ether. Commen cellulose eter sohmaxyprupylpropyl methylcellose (HPMC) uye hydroxytl Cellence

2. Molecular uremu

Iyo molecular uremu hwe cellulose ether ine mhedzisiro yakananga pakuchengeta kwayo kwemvura. Kazhinji, yakakura kwazvo inorema, yakakwira iyo visikoka yeCellulose ether uye yakasimba iyo hydrogel network network, inobatsira kuvandudza kuchengetwa kwemvura kwechinhu. Nekudaro, zvakanyanyisa kuremerwa kwemanyorerwe kunogona kuitawo kuderera mukuita kwekuvaka kwezvinhu, sekudzikira kwehunhu uye kusununguka kwekuvaka. Naizvozvo, mune zvinoshanda zvinoshandiswa, zvinodikanwa kuti uwane chiyero pakati pekuchengetwa kwemvura nekuita zvekuvaka.

3. Tembiricha uye humidity
Tembiricha uye humidyity zvinhu zvekunze kwezvakatipoteredza zvinokanganisa kuchengetwa kwemvura kwemheremellose. Sezvo tembiricha inosimuka, mwero wekubuda kwemvura anowedzera, uye cellulose vaitherinhu zvinoda kuchengetwa kwemvura zvine simba kuti utsungirire shanduko iyi. Munzvimbo yakanangana nehuremu hwakaderera, iko kudzokorora kwemvura kwekuita cellulose ana vanawo kwakakosha zvakare kudzivirira zvinyorwa kubva pakurasikirwa nemvura nekukurumidza pakuvaka.

Basa rekuchengetwa kwemvura mune dzakasiyana mashandisirwo
1. Chikumbiro muzvivakwa zvekuvaka
Muzvivakwa zvekuvaka, kuchengetwa kwemvura kwemasero kunonyanya kushandiswa mune zvigadzirwa zvakaita sevharanda uye kongiri. Kuchengeta kwemvura kwakakwirira kunogona kuve nechokwadi chekuti zvinyorwa zvine mvura yakakwana panguva yekuomesa, nekudaro ichivandudza simba rayo uye kusimba kwayo. Kunyanya muutete-wakaomeswa kuvaka kana kukwirira kwakasimba nzvimbo, kudzokorora kwemvura kwemvura kunogona kudzivirira matambudziko emhando dzakadai sekupaza uye poda rezvishandiso nekuda kwekukurumidza kurasikirwa kwemvura.

2. Kushandisa mune yekurapa munda
Muchiripo, ma cellause etana anowanzoshandiswa pakugadzirira mishonga sekambani, mafirimu emakambani uye anodzorwa vabati vamiriri. Kuchengetwa kwemvura kwayo hakusi kungobatsira kusunungurwa kwezvinodhaka mumuviri, asi zvakare kunovandudza kuwanda kwezvinodhaka. Uye zvakare, iyo nzvimbo yekuchengetedza mvura yemasero ye cellulose inoshandiswa zvakanyanya muzvigadzirwa zveganda zvekubatsira kubatsira kuchengetedza chiyero cheganda.

3. Chishandiso muindasitiri yechikafu
Cellulose ana ana anonyanya kushandiswa senhau, emulsifiers uye stabilizer mune indasitiri yechikafu. Chivakwa charo-chinochengetedza mvura chinobatsira kuvandudza kuravira uye kuumbwa kwechikafu, zvakadai sekunyorova muchingwa uye nepfuti, uye nekuwedzera hupenyu hwesherufu yezvigadzirwa.

Iyo yekuchengetedza mvura midziyo yemasero ye cellulose etihoshe ndiyo nheyo yebasa rayo rinokosha munzvimbo dzakawanda dzekushandisa. Nekutsiva dhigirii rekutsiva, suremu hweshoko uye kusarudza yakakodzera cellulose makomputa marudzi, izvo zvinodikanwa zvekuchengetedza mvura muminda yakasiyana inogona kusangana. Mune ramangwana, nekuvandudzwa kwesainzi uye tekinoroji, kushandiswa kwemasangano, kushandisirwa kwemaseroloko kuchawedzera zvakanyanya, uye kukosha kwenzvimbo yayo yekuchengetedza mvura muminda dzakasiyana siyana ichavharirwa.
