Thutong ea semelo le mechanism ea hydrophobel e fetotsoeng hydrophobied hydroullese ea hydrophobied hydroullese

Hydrophobic Celluloseseyl Hydrophobic ke mofuta oa li-hydrovavar tse tsoang ho lihlopha tse telele tsa hydrophobic, li-candroythyl celdlosese (hec). Mofuta ona oa boitsebiso o kopanya thepa ea hydrophilic ea hydroxethyl e nang le thepa ea hydrophoml ea lihlopha tsa hydrophom

1. Synthes mokhoa oa hydrophophobity e fetotsoeng hydropibethyl clloulose
Synthes of Hydrophobied hydrophobied hydrophonel conmloulose hangata e etsoa ke mekhoa e latelang:

Karabelo ea Essization
Mokhoa ona ke ho sebetsana le condroyebethyl - acid ea lik'hemik'hale ea hydrophob, jj Karabelo ea Esterance e ke ke ea hlahisa lihlopha tsa hydrophobic feela, empa hape e lokise hydrophobicity le matla a maholo a polymer. Maemo a karabelo a ts'ebetso ea Synthesis, joalo ka mocheso, nako, solvent le calyst e tla ama ts'ebetso ea sehlahisoa sa ho qetela.

1.2 Rection
Mokhoang ona, sehlopha sa hydroxyl sa clldroxethyl conluulose e nkeloa sebaka ke sehlopha sa hydrophobic (joalo ka Alkyl, Phenyl, ETC.). Monyetla oa mokhoa ona ke hore maemo ana ke a bonolo, litšobotsi tsa sebopeho sa hydroythyl li bolokiloe hantle, 'me hangata ho na le sehlahisoa se fetotsoeng le se atlehileng.

1.3 Boitšoaro ba bo-copolymerization
Ka ho ngolisoa ka mohono ka li-monomer tse ling (tse kang acrylic, e joalo, suymer e nang le hydrophobicity e ka lokisoa. Mokhoa ona o ka fihlela taolo e nepahetseng ea ts'ebetso ea thibelo ea cellulo ea cellulo ka ho fetola sekhahla sa bathusi ba fapaneng.

1.4 Rececation Rection
Litsomi tsa Hydrophobic li kene ka lik'hemik'hale sebopeho sa hydroxethyl celdrothyl cellulosese ho theha li-brydrophobic kapa likarolo. Mokhoa ona o ka ntlafatsa ts'ebetso e futhumetseng ea hydrophobeth e fetotsoeng celdrophonithyl e fetotsoeng condrophone e fetotsoeng, e loketseng litlhoko tse itseng tse sebetsang.

2. Mechanism ea thipa ea hydrophophobity e fetotsoeng hydroxethyl celdroullese
Mokhoa oa ho thetsa oa hydrophobied hydrophoned ka mydrophobied haholo-holo e nang le lintlha tse latelang:

2.1 eketsa litšebelisano tsa botona le botšehali
Kenyelletso ea lihlopha tsa hydrophobic li ntlafatsa litšebelisano tsa limolek'hule tsa limolek'hule tsa cellulose, haholo-holo tikolohong e senyehileng, moo lihlopha tsa hydrophobic li nang le li-calgregate tse kholo tsa molek'hule. Tšobotsi ena ea mahlahahlahla le etella pele ho eketseha ha tharollo, ka hona e bonts'a thepa e matla ea ho tšosa.

2,2 hydrophilic-hydrophobic Tšebeliso
Lihlopha tsa hydrophilic (tse kang hydroxethyl) le lihlopha tsa hydrophobic (tse kang Alkyphobicky Tšoseng ea Maiketsetso, karolo ea hydrophilic e sebelisana ka matla a metsi, ha hydrophostic e hohela tekanyo ea hydrophobic, ka hona e eketsa maikutlo.

2.3 Ho theha sebopeho sa marang-rang sa tharollo
Kamora ho fetoloa ha hydrophobic, sebopeho sa ketane ea molek'hule se ka fetoha, se etsa sebopeho se nang le mokhoa oa marang-rang tse fapaneng tse tharo. Sebopeho sena sa marang-rang se ka ntlafatsa haholo bokhoni ba li-incoselatlity le bokhoni bo matla ba tharollo ea sefapano sa mmele - limolek'hule.

2.4 Ho bonolo ho theha sebopeho se kang sa gel
Ka lebaka la kenyelletso ea lihlopha tsa hydrophobic, hydrophobied hydrophonethyl celdroullese e fetohileng Tlas'a maemo a loketseng, joalo ka liphetoho tsa mocheso, ph kapa khatello, ho ka baka sebopeho sa meaho ea sona ka tharollo.

3. Kopo ea hydrophobied hydrophoned ea hydrophobied hydroullese
Hydrophobic Cellrophobic CemfoubL e fetotsoe haholo masimong a mangata a indasteri, haholo-holo maemong ao ho a thusa, ho hlokahala ntlafatso ea ho ba le matla.

3.1 likhetla le lipente
Ka indasteri ea boloi ea bohloeki, hydrophoned celdrousebethyl celdroullelese ea Hydrophonel e ka ntlafatsa thepa ea Rheology

3.2 hloekisa le litšitiso
Ho eketsa celdrophobity e fetotsoeng hydrophoberyl e fetotsoeng ka kotloloho e ka ntlafatsa pono ea sesepa le se etsang ebile e bonolo ho e laola.

3.3 LITLHAKISO TSA BOPHELO
Tšimong ea litsotsi, hydrophone e fetotsoeng ea hydrophone e sebelisoa e le motho ea lihlong le ea ho emisa, haholo-holo ka litlolo, tse ka ntlafatsang sengoloa mme li ikutloe ka sehlahisoa.

3.4 Mojari oa lithethefatsi
Ka lebaka la ho holisa le ho feta celdrompberity, hydrophobied celdroulosethyl celdrouleseyl sistimi ea ho lokolloa, e ka laolang sekhahla sa litlhare tse laoloang ke lithethefatsi.

Ka ho hlahisa lihlopha tsa hydrophobic, hydrophobied hydrophonethyl celdroulese ea hydrokybethy Mechine ea eona ea ho thekesela e ipapisitse le tšebelisano lipakeng tsa lihlopha tsa hydrophobic, litlamorao tsa lisele tsa khale-kholo ka sebopeho sa tharollo. Ka ho tebisa lipatlisiso, mokhoa oa Synthesis le tšimo ea kopo ea hydrophobet e fetotsoeng cemdrophonebethyl e fetotsoeng, e tla tsoela pele ho holisa, ka tebello ea mrankrase e pharaletseng.
