Kugwiritsa Ntchito Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose (HEC)ndi ether ya cellulose yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera mu etherification yambiri. Ndi ufa woyera kapena granule wopanda fungo, wopanda kukoma, wopanda poizoni, womwe ungasungunuke m'madzi ozizira kuti upange yankho lowonekera bwino la viscous, ndipo kusungunuka sikukhudzidwa ndi pH. Ili ndi makulidwe, kumangirira, kufalitsa, kusakaniza, kupanga filimu, kuyimitsa, kuyamwa, kugwira ntchito pamwamba, kusunga chinyezi komanso kukana mchere. Imagwiritsidwa ntchito kwambiri mu utoto, zomangamanga, nsalu, mankhwala a tsiku ndi tsiku, mapepala, kuboola mafuta ndi mafakitale ena.

Madera akuluakulu ogwiritsira ntchito:

1. Utoto: Utoto wopangidwa ndi madzi ndi madzi okhuthala opangidwa ndi zosungunulira zachilengedwe kapena madzi opangidwa ndi utomoni, kapena mafuta, kapena emulsion, pamodzi ndi zowonjezera zofanana. Zophimba zopangidwa ndi madzi zomwe zili ndi magwiridwe antchito abwino ziyeneranso kukhala ndi magwiridwe antchito abwino, mphamvu yabwino yobisala, kumatira mwamphamvu, komanso magwiridwe antchito abwino osungira madzi; cellulose ether ndiye chinthu choyenera kwambiri chopangira zinthu izi.

2. Kapangidwe: Mu ntchito yomanga, HEC imagwiritsidwa ntchito ngati chowonjezera pa zinthu monga zipangizo za pakhoma, konkire (kuphatikizapo phula), matailosi omatidwa ndi zipangizo zomangira, zomwe zingawonjezere kukhuthala ndi makulidwe a zipangizo zomangira, kukonza kumatira, kukhuthala, ndi kusunga madzi. Kuonjezera mphamvu yopindika ya zigawo kapena zigawo, kukonza kuchepa, ndikupewa ming'alu ya m'mphepete.

3. Nsalu: Thonje, ulusi wopangidwa kapena zosakaniza zopangidwa ndi HEC zimawonjezera mphamvu zawo monga kukana kukanda, utoto, kukana moto ndi kukana madontho, komanso zimawonjezera kukhazikika kwa thupi lawo (kuchepa) ndi kulimba, makamaka ulusi wopangidwa, zomwe zimapangitsa kuti zikhale zosavuta kupuma komanso kuchepetsa mphamvu yamagetsi yosasunthika.

4. Mankhwala a tsiku ndi tsiku: Cellulose ether ndi chinthu chofunikira kwambiri mu mankhwala a tsiku ndi tsiku. Sichimangowonjezera kukhuthala kwa zodzoladzola zamadzimadzi kapena emulsion, komanso chimathandizira kufalikira ndi kukhazikika kwa thovu.

5.Pepala: Pakupanga mapepala, HEC ingagwiritsidwe ntchito ngati chothandizira kukula, chothandizira kulimbitsa ndi chosinthira mapepala.

6. Kuboola mafuta: HEC imagwiritsidwa ntchito makamaka ngati chinthu cholimbitsa ndi kukhazikika mu njira yochizira mafuta. Ndi mankhwala abwino kwambiri oboola mafuta. Inkagwiritsidwa ntchito kwambiri poboola, kumaliza zitsime, kuyika simenti ndi ntchito zina zopangira mafuta m'maiko akunja m'zaka za m'ma 1960.

Minda ina yogwiritsira ntchito:

HECingathandize kuphatika poizoni ku masamba popopera; HEC ingagwiritsidwe ntchito ngati chokhuthala cha ma emulsions opopera kuti achepetse kuyenda kwa mankhwala, motero kuwonjezera mphamvu yogwiritsira ntchito kupopera masamba. HEC ingagwiritsidwenso ntchito ngati chopangira filimu mu zophimba mbewu; ngati chomangira pobwezeretsanso masamba a fodya. Hydroxyethyl cellulose ingagwiritsidwe ntchito ngati chowonjezera kuti chiwonjezere magwiridwe antchito ophimba zinthu zosapsa ndi moto, ndipo yagwiritsidwa ntchito kwambiri pokonzekera "zothina" zosapsa ndi moto. Hydroxyethyl cellulose ingathandize mphamvu yonyowa komanso kufooka kwa mchenga wa simenti ndi sodium silicate sand systems. Hydroxyethyl cellulose ingagwiritsidwe ntchito popanga mafilimu komanso ngati chothina popanga ma microscopic slides. Chothina m'madzi okhala ndi mchere wambiri womwe umagwiritsidwa ntchito pokonza filimu. Imagwiritsidwa ntchito ngati chomangira komanso chothina chokhazikika cha zophimba za fluorescent mu zophimba za chubu cha fluorescent. Imatha kuteteza colloid ku mphamvu ya electrolyte; hydroxyethyl cellulose ingathandize kuyika mofanana mu cadmium plating solution. Ingagwiritsidwe ntchito kupanga zomangira zamphamvu kwambiri za ceramics. Zoletsa madzi zimaletsa chinyezi kulowa mu zingwe zowonongeka.
