HEC kuj tseem siv nyob rau hauv kev tsim cov tshuaj uas tso tawm, qhov chaw uas nws pab tswj cov kev tso tawm ntawm lub sijhawm ua kom nquag. Ntxiv mus, HEC yog ib qho tseem ceeb ntawm cov duab kos duab, xws li cream thiab tshuaj pleev, qhov uas nws muab cov tshuaj viscosity thiab ruaj khov.
5. Kev lag luam khoom noj
Txawm hais tias nws siv nyob rau hauv kev lag luam khoom noj muaj tsawg dua piv rau lwm cov haujlwm, HEC tseem pom cov ntawv thov ua haujlwm tuab thiab ruaj khov rau qee yam zaub mov. Nws tuaj yeem raug siv los txhim kho cov qauv thiab muaj cov khoom zoo sib xws, hnav khaub ncaws, thiab cov khoom qab zib. Ib qho ntxiv, HEC pab kom ruaj khov emulsions, tiv thaiv kev sib cais ntawm cov khoom xyaw thiab kom ua kom cov khoom lag luam tsis zoo. Nws cov khoom tsis muaj tshuaj lom thiab tsis muaj kev sib raug zoo ua rau nws muaj kev nyab xeeb rau kev siv hauv cov ntawv thov zaub mov, txawm tias nws siv yog tswj hwm kev nyab xeeb.
6. Textile Kev Lag Luam
Hauv kev lag luam textile, HEC tau ua haujlwm hauv cov sizing thiab xov tiav ntawm cov ntaub. Nws ua raws li kev tiv thaiv kev tiv thaiv hauv cov txheej txheem sizing, qhov chaw nws pab txhim kho lub zog thiab smoothness ntawm cov xov paj, txo cov plaub hau thaum nws. Hec tseem ua haujlwm rau cov tuab tuab hauv cov luam ntawv luam tawm, muab cov viscosity tsim nyog rau txawm tias daim ntawv thov thiab pigments. Qhov no ua rau Shaper, ntau cov qauv txhais thiab txhim kho cov xim tawm los.
7. Cov nplaum thiab cov xov xwm
HEC yog cov khoom tseem ceeb hauv ntau cov nplaum thiab kev sib sau ua ke. Nws cov khoom siv thickening txhim kho lub viscance thiab tackiness ntawm cov nplaum, ua rau lawv yooj yim rau kev thov thiab txhim kho lawv lub zog. Hauv kev muab khi, hec pab tswj qhov kev ntws thiab sag ntawm cov khoom, kom nws nyob qis qis hauv qhov chaw thov. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov xws li kev ua ke tsim kev ua ke, uas muaj kev ntseeg siab thiab ruaj khov yog qhov yuav tsum tau ua.
8. Cov roj thiab roj kev lag luam
Hauv cov roj thiab roj kev lag luam, hec yog siv rau hauv cov kua dej drilling thiab fracturing kua.
