Kodi kukhuthala kwa hydroxyethyl cellulose ndi chiyani?

Hydroxyethylcellulose (HEC) ndi nonionic, madzi sungunuka polima yochokera ku cellulose. Chifukwa cha mawonekedwe ake apadera a rheological, amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikizapo mankhwala, zodzoladzola ndi zomangamanga. Chimodzi mwazinthu zazikulu za hydroxyethyl cellulose ndi kukhuthala kwake, komwe kumagwira ntchito yofunika kwambiri pakuzindikira momwe amagwirira ntchito zosiyanasiyana.

Viscosity ndi muyeso wa kukana kwamadzimadzi kuyenda. Pankhani ya hydroxyethylcellulose, kukhuthala kwake kumakhudzidwa ndi zinthu zingapo, kuphatikizapo ndende, kutentha ndi kumeta ubweya. Kumvetsetsa zinthu izi ndikofunikira pakuwongolera kugwiritsa ntchito HEC mumitundu yosiyanasiyana.

The mamasukidwe akayendedwe wa hydroxyethylcellulose kwambiri zimadalira ake ndende mu njira. Kawirikawiri, pamene ndende ya HEC ikuwonjezeka, kukhuthala kwake kumawonjezekanso. Khalidwe ili ndilofanana ndi mayankho a polima ndipo nthawi zambiri limafotokozedwa ndi lamulo lamphamvu lomwe limakhudzana ndi kukhuthala kwa ndende.

Kutentha kumakhudzanso kukhuthala kwa hydroxyethyl cellulose solutions. Nthawi zambiri, mamasukidwe akayendedwe amachepetsa ndi kuwonjezeka kutentha. Kutentha kwa kutenthaku ndikofunika kwambiri pa ntchito zomwe zipangizo zimafunikira kusintha kwa viscosity, monga panthawi yopanga kapena kugwiritsidwa ntchito kumalo osiyanasiyana.

Kumeta ubweya ndi chinthu china chofunikira chomwe chimakhudza kukhuthala kwa hydroxyethyl cellulose. Shear rate imatanthawuza kuchuluka komwe zigawo zamadzimadzi zoyandikana zimasunthika potengerana. Kukhuthala kwa mayankho a HEC nthawi zambiri kumawonetsa kumeta ubweya wa ubweya, kutanthauza kuti kuchuluka kwa kukameta ubweya kumawonjezeka, kukhuthala kumachepa. Katunduyu ndi wopindulitsa pakugwiritsa ntchito monga zokutira ndi zomatira komwe kumafunikira kugwiritsa ntchito mosavuta.

Kulemera kwa maselo a hydroxyethyl cellulose kumatsimikiziranso kukhuthala kwake. Ma molekyulu apamwamba a HECs amakhala ndi ma viscosity apamwamba pamlingo womwe wapatsidwa. Mkhalidwewu ndi wofunikira posankha kalasi inayake ya HEC pa ntchito inayake.

Mu mankhwala formulations, hydroxyethylcellulose ambiri ntchito monga thickening wothandizira m`kamwa ndi apakhungu mlingo mitundu. Kukhuthala kwa HEC kumatsimikizira kuyimitsidwa koyenera kwa tinthu tating'onoting'ono ndipo kumapereka kusasinthika kofunikira kwa dosing kosavuta. Kuwonjezera apo, khalidwe lometa ubweya wa HEC likhoza kupititsa patsogolo kufalikira kwa mapangidwe apamutu.

M'makampani azodzikongoletsera, hydroxyethylcellulose imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza ma shampoos, mafuta odzola ndi zonona. Mawonekedwe ake osintha mawonekedwe a viscosity amathandizira kukhazikika ndi kapangidwe kazinthu izi, potero zimakulitsa luso la ogwiritsa ntchito.

M'makampani omanga, hydroxyethylcellulose nthawi zambiri amagwiritsidwa ntchito ngati thickener muzinthu zopangidwa ndi simenti. The mamasukidwe akayendedwe a HEC kumathandiza kulamulira otaya ndi processability zinthu pa ntchito. Izi ndizofunikira makamaka pazogwiritsa ntchito monga zomatira matailosi ndi ma grouts.

Kukhuthala kwa hydroxyethyl cellulose ndi gawo lofunikira lomwe limakhudza magwiridwe antchito osiyanasiyana. Kumvetsetsa zinthu zomwe zimakhudza ma viscosity, monga kukhazikika, kutentha, ndi kumeta ubweya wa ubweya, ndizofunika kwambiri kuti mugwiritse ntchito HEC m'mafakitale osiyanasiyana. Monga polima wosunthika, hydroxyethyl cellulose ikupitilizabe kuchita gawo lofunikira pakuwongolera magwiridwe antchito azinthu zosiyanasiyana m'mafakitale osiyanasiyana.
