Dzidza pane synthesis uye akakora mashini e hydrophobically yakagadziridzwa hydroxyll cellose

Hydrophobic yakagadziridzwa hydroxyl cellethyl cellerethyl (Hec) rudzi rwekutsanangurwa nekuburitsa mapoka eHykutoro (senge mapoka alkyl, etc.) ku hydroxytl cellulose (Hec). Rudzi urwu rwezvinyorwa zvinosanganisira hydrophilic remafuma yeHydroxethyl CellerTHE neHydrophobic Zvivakwa zveHydrophobic mapoka uye inoshandiswa zvakanyanya mumatombo, marara, cosmetics uye cosmetics uye zvinodhaka uye zvinodhaka.

1. Synthesis nzira yehydrophobically yakagadziridzwa hydroxyl cellelose
Iyo synthesis yehydrophobically yakagadziridzwa hydroxyl cellows inowanzoitwa nenzira inotevera nzira:

1.1 Enderuti Reaction
Iyi nzira ndeyekuita hydroxythyl cellermakemakemikomani recids (yakadai sekureba-keteni yemagetsi, etc. Essification yekuita haigone kuunza zvinyatsounza hydrophobic mapoka, asi zvakare gadziridza hydrophobicity uye inokonzeresa polymers. Mamiriro ekuita eSynthesis maitiro, akadai sekupisa, nguva, kuita solvent uye kuchinjisa, kuchakanganisa kuita kwechigadzirwa chekupedzisira.

1.2 Substition Reaction
Nenzira iyi, iyo hydroxyl boka re hydroxylthyl cellulose inotsiviwa neiyo hydrophobic boka (senge Alkyl, phenyl, etc.). Kubatsira kwenzira iyi ndekwekuti mamiriro eSynthesis ane hukama hunyoro, hunhu hwe hydroxeksetl cellery anogona kunyatsochengetedzwa, uye chigadzirwa chakashandurwa chinowanzove neyakagwinya.

1.3 Copolymerization Reaction
NaCopolymerizing nevamwe vanosemesa (senge acrylic acid, acrylate, nezvimwewo), polymer nyowani ne hydrophos inogona kugadzirira. Iyi nzira inogona kuzadzisa kudzora chaiko kwekuita kwekuita cellulose nekugadzirisa huwandu hwevanhu vakasiyana vanogunun'una vakasiyana.

1.4 kuwirirana kuita
Hydrophobic makomputa emakemikari akanyorwa muchimiro chehydroxytHyl cellulose kuumba hydrophobic zvidhinha kana zvikamu. Iyi nzira inogona kusimudzira kugadzikana kweiyo yekunyora uye nzvimbo yemukati yehydrophobically yakagadziridzwa hydroxyl cellyl cellows, iyo yakakodzera kune chaiyo-maitiro ekuita.

2.
Iyo inoshamisa michina ye hydrophobically yakagadziridzwa hydroxyl cellever inonyanya kuve nezvinhu zvinotevera:

2.1 Wedzera intermolecular kutaurirana
Sumo yemapoka eHydrophic inokwidziridzwa kufambidzana pakati pema cellulose Molecules, kunyanya mumativi emvura, uko mapoka eHydrobhic anowanzowedzera pamwe chete kuti vaumbe mahorari akaungana. Uku kushamwaridzana kushamisika kunotungamira mukuwedzera kweiyo viscosity yemhinduro, nekudaro ichiratidza nzvimbo yakasimba yakashata.

2.2 hydrophilic-hydrophobic kudyidzana
Mapoka eHydrophic (akadai seHydroxyTH) uye hydrophobic mapoka (akadai sealkyl, phenyl, phenyl, phenyl, phenyl, phenyl, phenyl, phenyl, phenyl, phenyl. Muchikamu chemvura, iyo hydrophilic chikamu chakasimba nemamolekyudhi emvura, nepo hydrophobic chikamu chinokwezva mumwe nemumwe kuburikidza nehydrophobic mhedzisiro, ichiwedzera kuwedzera kurongeka pakati pemamolekyudhi uye nekudaro kuwedzeredza viscosity.

2.3 Kugadzira iyo network network yemhinduro
Mushure mekugadziriswa kwehydrophobic, chimiro cheiyo molecular cheni chinogona kuchinja, kugadzira yakasimba matatu-dimensional network network network. Iyi network network inogona kugadzirisa zvakanyanya iyo viscoelasticity uye kugona kugona kwemhinduro kuburikidza nekubatanidza mumuviri-pakati pemamorekuru.

2.4 Zviri nyore kuumba gel-kunge chimiro
Nekuda kwekutanga kweiyo hydrophobic mapoka, hydrophobically yakagadziriswa hydroxyll cellulose ine yakanaka magariro. Pasi pemamiriro ezvinhu akakodzera, sekuchinja kwekushisa, ph kana pfungwa, hydrophobic mapoka akagadziridzwa anogona kukonzera kuumbwa kweiyo glasures mune mhinduro, iyo zvakare kuratidzwa kwezvinhu zvaro zvakashata.

3. Kushandiswa kwehydrophobically yakagadziridzwa hydroxyll cellelose
Hydrophobic yakagadziridzwa hydroxyll celler inoshandiswa zvakanyanya muminda yakawanda yeindasitiri, kunyanya mumamiriro ezvinhu emagetsi ekugadzirisa,

3.1 majasi uye pendi
Mujasidhi yejasi, hydrophobically yakagadziridzwa hydroxethyl cellerethyl cellows inokwanisa kuvandudza zvivakwa, kuita kwekuvandudza kwemvura, uku uchizovandudza mari kupokana nekukanda mari yekubatira.

3.2 Clecheners uye inodzivirira
Kuwedzera hydrophobically yakagadziridzwa hydroxyl cellethyl cellentheseth cellenting inogona kunatsiridza zvinobudirira zvevisikopo zveiyo detergent, ichiita kuti ive yakagadzikana uye iri nyore kudzora panguva yekushandisa.

3.3 cosmetics
MuCosmetics munda, hydrophobically yakagadziridzwa hydroxethyl cellereth inowanzo shandiswa seyakavharwa uye nekumirisa mumiririri, kunyanya mune zvimwe zvigadzirwa, izvo zvinogona kuvandudza chimiro uye chinzwa chechigadzirwa.

3.4 Mutakuri wezvinodhaka
Nekuda kwekunyepedzera kwayo kwakanaka uye kusarudzika, hydrophobically yakagadziridzwa hydroxethyl cellulose

Nekusuma mapoka eHydrophic, hydrophobically yakagadziridzwa hydroxethyl cellethyl hydroxaketHyl mherkomberyth maitiro, asi zvakare zvinoita kuti zvinoratidza kuita kwakanakisa mune dzakasiyana siyana dzekushandisa. Scomplism yayo inonyanya kuenderana nekudyidzana pakati pehydrophobic mapoka uye hydrophic mapoka, mamorekuru eggreging mhedzisiro uye shanduko mune yekugadzirisa chimiro. Nekunonoka kwekutsvagisa, iyo nzira yeSynthesis uye yeSynthesis Nzira yeiyo hydrophobically yakagadziridzwa hydroxyl hydroxeksl cellows ichave yakawedzera kuwedzerwa, ine triph tarisiro yemusika.
