Ingabe ukwandisa i-viscosity ye-cellulose ether kuzonyusa izinga lokugeleza?

Ukwandisa i-viscosity yama-cellulose ether ngokuvamile kunciphisa izinga lokugeleza kwesisombululo.I-Cellulose ethers iyiqembu lama-polymers ancibilika emanzini atholakala ku-cellulose avame ukusetshenziswa ezimbonini ezihlukahlukene, kuhlanganise nemithi, ukudla, kanye nokwakha.I-viscosity yesisombululo isilinganiso sokumelana kwaso nokugeleza futhi kuthintwa izici ezifana nokugxilisa ingqondo, izinga lokushisa, nesisindo samangqamuzana e-cellulose ether.

Nansi incazelo enemininingwane yokuthi ukwanda kwe-cellulose ether viscosity kulithinta kanjani izinga lokugeleza:

Ubudlelwano phakathi kwe-viscosity nezinga lokugeleza:

I-viscosity ukungqubuzana kwangaphakathi ngaphakathi koketshezi olumelana nokugeleza kwalo.Ikalwa ngamayunithi afana ne-centipoise (cP) noma imizuzwana ye-pascal (Pa·s).
Izinga lokugeleza kwesixazululo lihambisana ngokuphambene ne-viscosity yaso.I-viscosity ephakeme isho ukumelana okukhulu nokugeleza, okuholela emazingeni aphansi okugeleza.

Izici ze-Cellulose ether:

I-cellulose ethers ivame ukungezwa kwisixazululo sokuguqula izakhiwo zayo ze-rheological.Izinhlobo ezijwayelekile zifaka i-methylcellulose (MC), i-hydroxypropylcellulose (HPC), ne-carboxymethylcellulose (CMC).
I-viscosity yezixazululo ze-cellulose ether incike ezintweni ezifana nokugxila, izinga lokushisa kanye nesilinganiso se-shear.

Umthelela wokugxila:

Ukwandisa ukugcwala kwama-cellulose ethers ngokuvamile kukhulisa i-viscosity.Lokhu kungenxa yokuthi ukugxila okuphezulu kusho amaketanga e-polymer amaningi esixazululweni, okuholela ekuqineni kokugeleza okukhulu.

Umthelela wezinga lokushisa:

Izinga lokushisa lithinta i-viscosity yama-cellulose ethers.Kwezinye izimo, njengoba izinga lokushisa likhuphuka, i-viscosity iyancipha.Nokho, lobu budlelwano bungase buhluke kuye ngohlobo oluthile lwe-cellulose ether kanye nezixazululo zayo.

Ukuncika kwezinga le-Shear:

I-viscosity yezixazululo ze-cellulose ether ngokuvamile incike kuzinga lokugunda.Emazingeni aphezulu okugunda (isibonelo, ngesikhathi sokumpompa noma ukuxutshwa), i-viscosity ingase yehle ngenxa yokuziphatha kokugunda kwe-shear.

Umthelela kuthrafikhi:

Ukwenyuka kwe-viscosity ye-cellulose ether kungabangela ukuncishiswa kwamazinga okugeleza ezinqubweni ezidinga ukuthutha, ukupompa, noma ukusabalalisa izixazululo.Lokhu kuhambisana nezicelo ezinjengama-coatings, ama-adhesives kanye nokwakheka kwemithi.

Amanothi ohlelo lokusebenza:

Nakuba kungase kudingeke ama-viscosity aphezulu kwezinye izinhlelo zokusebenza ukuze kuthuthukiswe ukusebenza komkhiqizo noma ukuzinza, lokhu kufanele kulinganiswe nezici ezingokoqobo zokuphatha nokucubungula.

Ukulungiselelwa kweresiphi:

Abakhiqizi bavame ukuthuthukisa ukugxilwa kwe-cellulose ether kanye neminye imingcele yokwakheka ukuze kuzuzwe i-viscosity edingekayo yohlelo oluthile ngaphandle kokuphazamisa ukugeleza ngezinga elingamukeleki.

Ukwenyuka kwe-viscosity ye-cellulose ether ngokuvamile kubangela ukwehla kwezinga lokugeleza ngenxa yokwanda kokumelana nokugeleza.Kodwa-ke, ubudlelwano obunembile buthintwa yizici ezifana nokugxilisa ingqondo, izinga lokushisa kanye nesilinganiso sokugunda, futhi ukulungiswa kokubunjwa kungenziwa ukuze kuzuzwe ibhalansi oyifunayo phakathi kwe-viscosity nokugeleza.
