Cov teebmeem ntawm Hydroxy Ethyl Cellulose ntawm Dej-Raws Txheej Txheej

Hydroxyethyl cellulose (HEC) yog ib qho tshuaj ntxiv rau hauv cov txheej txheem dej vim nws muaj peev xwm txhim kho cov khoom ntawm txheej. Nov yog qee qhov cuam tshuam ntawm HEC ntawm cov txheej txheem dej:

1. Thickening: HEC yog cov dej-soluble polymer uas tuaj yeem ua kom cov viscosity ntawm cov dej-raws li txheej txheej, ua rau lawv yooj yim rau kev thov thiab txhim kho lawv cov dej ntws. Cov nyhuv thickening ntawm HEC kuj tuaj yeem pab tiv thaiv sagging thiab poob.
2. Stabilization: HEC tuaj yeem txhim kho cov txheej txheem dej los ntawm kev tiv thaiv kev sib cais ntawm cov khoom xyaw thiab ua kom ntseeg tau tias lawv nyob twj ywm tsis tu ncua. Qhov no yuav pab txhim kho tag nrho qhov zoo thiab sib xws ntawm txheej.
3. Kev tsim cov yeeb yaj kiab: HEC tuaj yeem tsim cov yeeb yaj kiab muaj zog thiab hloov tau yooj yim thaum nws suav nrog cov txheej txheem dej. Cov yeeb yaj kiab no tuaj yeem txhim kho cov txheej txheem durability, adhesion, thiab tiv thaiv dej.
4. Kev hloov kho Rheology: HEC tuaj yeem hloov kho rheology ntawm cov txheej txheem dej los ntawm kev txhim kho lawv tus cwj pwm shear thinning. Qhov no txhais tau hais tias cov txheej yuav dhau los ua thinner thaum nws siv, ua kom yooj yim rau kev sib kis, tab sis nws yuav ua tuab dua thaum nws tsis tau thov, uas yuav pab nws ua raws li qhov chaw.
5. Kev tuav dej: HEC tuaj yeem pab khaws cov dej hauv cov txheej txheem dej, uas tuaj yeem tiv thaiv lawv kom qhuav sai heev. Qhov no tuaj yeem pab tau tshwj xeeb hauv qhov chaw kub lossis qhuav, qhov twg cov coatings tuaj yeem qhuav sai heev thiab ua nkig.

Zuag qhia tag nrho, HEC tuaj yeem txhim kho kev ua haujlwm ntawm cov txheej txheem dej los ntawm kev txhim kho lawv cov thickening, stabilization, tsim zaj duab xis, rheology, thiab dej tuav cov khoom. Nws yog ntau yam additives uas yuav siv tau nyob rau hauv ntau yam ntawm coatings, nrog rau cov xim, primers, thiab varnishes.
