Kuomesa mechanic of cellulose ether mune dzakasiyana-siyana application

Cellulose ether iboka remvura-soluble polymer zvinhu zvinowanikwa nemakemikari kugadziridzwa kwemasikirwo emusikirwo cellulose. Cellulose Cellulose ethyl inosanganisira methyl cellel Iyo huru michina seyenzi inosanganisira iyo yemuviri uye yemakemikari zvivakwa zvekudyidzana pakati pemolecular chimiro uye mhinduro.

1. Molecular chimiro che cellulose ether
Cellulose ether inoumbwa nekuunza dzakasiyana siki (senge methyl, ethyl, hydroxypruppropyl, nezvimwewo) kune iyo yekare cellulose keteni. Maitiro aya anochengetedza mutsara weiyo cellulose asi inoshandura iyo solubility uye mhinduro maitiro. Iko kusuma kwevatsidzike kunoita kuti minwe inoita kuti minwelean they

2. Molecular maitiro ekugadzirisa
Iko kukonzeresa mhedzisiro ye cellulose ether mumvura inonyanya kuuya kubva kune yakakwira viscosity network network chimiro chakaumbwa nemamorekuru ayo mumhinduro. Iyo chaiyo nzira inosanganisira:

2.1 kuzvimba uye kutambanudza kwemaketani anonyora
Kana cellulose ether yakanyungudutswa mumvura, macromolecular ngetani dzinopika nekuda kwehydration. Aya maComs ane molecular maketani anotambanudza uye agoronga vhoriyamu yakakura, kuwedzera zvakanyanya zvisizvo zvemhinduro. Uku kutambanudza uye kuzvimba kunoenderana nerudzi uye degree rekutsiva kwemheremelle ether vanoongorora, pamwe nekushisa uye pro kukosha kwemhinduro.

2.2 Intermolecular Hydrogen zvisungo uye hydrophobic kudyidzana
Cellulose ether molecular maketani ane nhamba yakakura yehydroxyl mapoka uye mamwe mapoka ehydropilic, ayo anogona kuumba masangano akasimba nemamolekyudhi emvura kuburikidza neHydrogen zvisungo zveHydrogen. Uye zvakare, ivo vanodzika cellulose ether kazhinji vane imwe mwero we hydrophos; Mhedzisiro yakasanganiswa yeHydrogen zvisungo uye hydrophobic kudyidzana inobvumira iyo cellulose ether mhinduro yekugadzira yakagadzikana yakakwira-viscosity state.

2.3 Intanglement uye kuyambuka mumuviri pakati pemanyorerwo
Cellulose ether mauralecococo orchemakeyitani yekunyora mumhinduro nekuda kweiyo polution nekuda kwekutora kwemitambo uye intermolecular mauto, uye aya majista anowedzera iyo visikopa yemhinduro. Uye zvakare, pakakwirira, cellulose ether mamorekuru anogona kuumba chimiro chakafanana nekubatanidza muviri, izvo zvinowedzera zvinosimbisa visikopa yemhinduro.

3. Kuomesa mashini mune chaiyo application

3.1 zvigadzirwa zvekuvaka
Muzvivakwa zvekuvaka, cellaulose etana kazhinji zvinowanzoshandiswa sehana mumarobhoti nemakonzo. Vanogona kuwedzera basa rekuvaka uye kuchengetwa kwemvura kwemauto, nekudaro vachivandudza kurerukirwa kwekuvaka uye kunaka kwekupedzisira kwezvivakwa. Mhedzisiro inoshamisa ye cellulose aungana mune izvi zvekushandisa inonyanya kubudikidza nekuumbwa kwemhinduro dzakakwirira-viscosity, kuwedzera kudenha uye anti-sagging zvivakwa.

3.2 Chikafu Chikafu
Muindasitiri yechikafu, cellulose ethers dzakadai soH HydroxyprusleselSellulose (HPMC) uye hydroxytHyl Cellense (HEC) inoshandiswa seiri thihkizers, stabilizer uye emlsifiger. Iyo yakakwira-viscosity mhinduro dzavanogadzira mune chikafu dzinogona kuwedzera kuravira uye kuumbwa kwechikafu, uku kusimudzira hurongwa hwakadzikira pakudya kudzivirira kuoma uye kupusa.

3.3 mushonga uye cosmetics
Mumunda wekurapa uye cosmetics, cellaulose ethers anoshandiswa kunge magweta uye mitezo yegadziriro yezvigadzirwa senge gomba, lotions nemakiromita. Shini yayo inosemesa inoenderana nemaitiro ayo ekunyungudika mumvura uye iyo yakakwira-vcosity network chimiro chakaumbwa, kupa iyo viscosity uye kugadzikana kunodiwa nechigadzirwa.

4. Iyo pesvedzero yezvinhu zvakatipoteredza pane zvakakora mhedzisiro
Iko kukonzeresa mhedzisiro ye cellulose ether inokanganiswa nezvinhu zvakasiyana-siyana zvezvakatipoteredza, kusanganisira tembiricha, ph kukosha uye ionic simba remhinduro. Izvi zvinhu zvinogona kuchinja dhigirii yekuzvimba uye kufambidzana kwekudyidzana kweiyo cellulose ether molecular cheni, nekudaro ichikanganisa zvevisiko zvemhinduro. Semuenzaniso, tembiricha yakakwira inowanzo dzora zvevasikirwo e cellulose mhinduro, nepo shanduko muP kukosha inogona kuchinja ionization yemazwi emamonzo, nekudaro achikanganisa viscosity.

Iyo yakasindimara yekushandisa cellulose ether seyakakonzerwa neyakagadzirirwa iyo yakasarudzika moleky chimiro uye yakakwira-viscosity network chimiro chakagadzirwa mumvura. Nokunzwisisa michina yayo inoshamisa mumanyorero akasiyana, maitiro ayo ekunyorera muminda dzakasiyana-siyana maindasitiri anogona kuve nani akagadziridzwa. Mune ramangwana, nekudzika kwakadzama kwehukama pakati pe cellulose ether chimiro uye kuita, zvinotarisirwa kuti cellulose ether zvigadzirwa zvine chekuita nekugadziriswa kwekuita zvinodiwa neminda dzakasiyana.
